一、2010年3月3日上午海关面试真题
有的时候制定决策会发现实施起来慢慢会与计划产生偏差,甚至最后的结果完全背离计划,管理学上叫做离心 力现象。结合经历谈。(2010年3月3日上午海关面试真题)
解题思路:
运用两分法分析离心力现象。
适当举例。
结合自身实际,谈论
参考要点:
离心力现象反映了计划与执行之间的辩证关系。在日常生活中也是常见的,对于这个问题我们要具体问题具体 分析,采取不同的解决措施以不断的促进决策与执行的相统一。
产生离心力现象可能有如下原因。首先,要考虑决策是否正确,如果是由于决策制定失误而导致无法实施,则 要分析造成决策失误的原因,在以后的决策过程中汲取经验,加强组织、调研,全面细致分析总结,从而制定正确 的决策。其次,如果决策相对合理,在实施的过程中,出现了突发的情况或者其他状况,则要分析实施过程中的问 题,不断的调整,提高执行力,以期更好地执行决策。
对于我自身而言,这个问题也曾经出现过。在我的毕业论文调研过程中,我在调研之前写了调研计划,相当于 题目中的决策,但是在后来的实际调研中,我发现我的调研活动与我的计划有很大出入。经过仔细分析,发现问题 在于在写计划时,没有结合调查点的时间情况制定相应的计划,而是想当然按照自己的想法去订计划,这直接导致 严重脱离实际,理论与实践相背离。通过调研过程的不断修正,最终保证了论文的顺利完成。
这个事情给了我很大的启发,今后走上公务员工作岗位,会不断地以此鞭策自己,加强自身修养,严谨制定决 策,同时,对已经确定的决策,要积极贯彻执行,并在实际工作中不断寻找更优的解决方式。
1、 我国如何在保证经济发展的同时发展低碳经济。
解题思路:
1.发展低碳经济提出的社会背景。
2.发展低碳经济的重要性。
3.发展低碳经济的有效措施。
4.展望。
参考要点:
发展低碳经济作为协调社会经济发展、保障能源安全与应对气候变化的基本途径,正逐渐被越来越多的国家认 同,成为全球性的共识与探索。在相当长的时间里,我国的经济发展主要依靠大量消耗能源资源来推动。这一过程 的代价是巨大的, shape up shoes,教训是深刻的,有必要探索一条实现经济发展与资源环境保护双赢的发展模式。作为经济社会发展模式的新探索 ,发展低碳经济是一项涉及经济、政治、文化、社会各个方面的系统工程,需要统一认识、健全法规,完善规划、 夯实基础,落实各项保障措施,全面推进我国应对气候变化事业发展与改革各项工作。
我国要发展低碳经济,可以采取如下措施, shape up skechers。1、继续制定全国及地区节能降耗约束性指标,大力推广节能省地绿色型建筑,加快城市快速公交和轨道交通建 设,大力宣传低碳消费理念和低碳行为好的做法,引导城乡居民转变消费观念。2、转变经济发展方式,推进产业 结构的战略性调整,大力发展高新技术产业和现代服务业,大力发展服务贸易,着力构建低碳发展产业。进一步强 化抑制高耗能和高排放产品的出口政策,努力开发和生产高附加值、低能耗产品,实现整个产业结构的低碳化。3 、大力发展清洁能源,着力提升太阳能等可再生能源的比重,引导和鼓励农村居民发展使用沼气,利用生产生活物 质原料,促进新能源的加快发展。4、加大科技投入,促进低碳技术创新。把可再生能源、先进核能、碳捕集和封 存等先进低碳技术作为提升国家技术竞争力的核心内容,列入国家和地区科技发展规划。
我国发展低碳经济是走可持续性发展的并由之路,在全民低碳理念的支持之下,结合我国政府经济推进低碳经 济的有效措施,能够更好更快的推进我国的经济发展。
二、2010年3月3日边检、铁路公安、国税、统计局调查队面试真题
真题:农民工子弟的学校,因为土地原因,教学楼楼顶建了塑胶跑道,谈谈你的看法。
试题类别:社会热点社会事件分析
能力考核:综合分析能力+语言表达能力+社会
答题主线:事件本身分析+事件引申提观点+结合社会方针给出建议对策
参考答案:
【是什么】(1)随着我国城市化进程的推进,越来越多的农民工来到城市打工挣钱,由此产生了跟随来到城 市的农民工子女的教育问题。由于我国现实国情,很多农民工子弟学校存在着教学资源少,教学不规范,学生安全 存在隐患等问题。如本题中,跑道建在楼顶,学生在娱乐过程中存在着很大的安全隐患。
【为什么】(2)造成这个现象的主要原因是教育资源分配不均问题。社会上的弱势群体不能够享有同等的教 育机会,一些地方政府对农民工子弟的教育投入也严重不足。农民工子弟在受教育过程中一直处于无法享受公平对 待,各地民工子弟学校几乎都面过办学资金不足、办学条件简陋、师资力量薄弱、办学地点“动荡漂泊”。尽管这 些年政府高度关注,出台了不少相关政策保障农民工子女就学,也取得不错成绩。但现阶段的基本国情和人口发展 趋势决定了农民工子女教育是我国教育事业发展面临的一项长期任务。
【怎么办】(3)教育公平是社会公平之根本。特别是对于农民工子弟这一特殊的弱势群体,我们应给予更多 的关心和爱护。首先,各地政府必须首先在思想上认识到农民工子弟能公平享受教育资源对社会稳定的重要性。农 民工子女与城市孩子同样是祖国的未来,同样有接受义务教育的权利;其次,各级政府要加大对弱势群体教育的投 入,将较多承担农民工子女就学学校的建设列入城市基础设施建设规划。各地财政部门要安排必要经费,对接收农 民工子女就学较多的学校给予补助,如通过设立助学金、减免费用、免费提供教科书等方式,帮助家庭经济困难的 农民工子女就学;最后,加快发展农村经济,消除城乡差距,同时加快户籍制度改革,通过建立完善的保障农民工 子女接受义务教育的制度和机制,才能从根本上解决此类问题。

1、校车安全演习,车上的小孩子以为真的出了安全事故,不停的哭喊,还用逃生锤弄碎了玻璃,围观的群众 也以为发生了安全事故,纷纷议论,你是这次演习的负责人,该如何处理?
【考查能力】:应急应变能力、解决问题的能力
【参考答案〕:作为一个负责人,对学生进行安全演习发生惊慌失措砸玻璃的情况,我是有不可推卸的责任的 。但是现在更重要的是眼前的问题,如何安抚学生的情绪、如何保证学生的安全、如何控制这样的场面才是最为重 要的。所以,我会第一时间启动本次演习的应急预案。
首先,依照应急预案,确保演习现场的秩序,并组织人员隔离演习现场。同时,组织老师制止学生砸玻璃的行 为,并安抚学生的情绪,告诉他们这只是一次演习,让他们不要惊慌。如果有学生受伤的话,则由专人负责联系在 场的医护人员。如果没有学生受伤,则在尽快的时间内,稳定所有学生的情绪,并清点学生的人数,防止在混乱之 中,有学生丢失。

五、2010年3月4日上午海关面试真题
1、有人说,拥有一副好牌,不如有好的打法,请谈谈你的看法。
【考察能力】:综合分析能力、逻辑思维能力、语言表达能力
【参考答案】:有人说,“拥有一副好牌,不如有好的打法”,这句话是在告诉我们“好牌”和“好的打法” 之间的关系,认为好的打法更重要,其实二者不是谁比谁更重要的关系,而是当我们遇到不同状况时候,我们应该 怎么办的问题。对于这句话我是这样理解的:
我们在打牌的时候,都希望能拥有一副好牌,再加上有好的打法,那么势必会在这场博弈中赢得胜利;当我们 拥有一副好牌,而没有好好去经营,没有好的打法的时候又会怎么样呢?而且,运气不会永远站在我们这边,多数 时候我们不会拿到好牌,相反也许会很糟糕,那么这个时候我们应该怎么办呢?是缴械投降,还是用好的打法转败 为胜?
打牌如此,我们的人生又何尝不是如此呢?当我们拥有良好的家庭背景的时候,当我们拥有过人的天资的时候 ,当我们拥有难得的机遇的时候,我们不自以为是、不洋洋得意、不目空一切,我们善于利用、积极进取、顽强拼 搏,我相信成功一定不会离我们太遥远, skechers shape up shoes。
相反,有些人或是因为家世的显赫,或是因为天资的聪颖,或是因为机遇的再三惠顾,便自以为了不起,从而 不思进取起来,洋洋自得起来,最后反而“沦为众人尔”。而还有些人,虽然没有很好的先天的条件,却始终坚持 自己的理想,不抛弃、不放弃,一步一个脚印,稳扎稳打,最终也找到了属于自己的一片天地,实现了自己的人身 价值和社会价值。一代京剧大师梅兰芳,我相信大家都不会陌生,梅老师的眼睛本来没有那么的流转有神,但为了 使自己的眼波如水,为了能在舞台上呈现给观众更好的表演,他每天仰望天空飞燕、低俯水中金鱼,坚持不懈,最 终得到了观众的认可,成为了一代大师。这样的例子数不胜数。
我们羡慕那些取得成功的人,总是看到别人拥有的鲜花、掌声和光环,看到别人背后的先天条件,但是我们更 应该看到的难道不应该是他们后天的努力和拼搏吗?我想这才是成功的关键所在。
所以,当我们走在人生的道路上,无论是抓了一副好牌还是坏牌,我们都要认真对待,找到正确的打法,这样 才是正确的态度,才有成功的可能。如果我们拥有了一副好牌,我们要善打、会打,否则再好的牌也不会是成功的 保证;而当我们不幸抓取了一副不好的牌,我们也不要怨天尤人、顾影自怜,通过自己的努力和拼搏,一定也能取 得成功。

【考查能力】沟通协调能力、分析解决问题能力、语言表达能力
【参考答案】
单位计划召开一个全国性的会议,那么预算的通过对于会议的筹备、开展都至关重要,所有我一定会努力做好 预算,争取财务部门的批准。但是如果我负责做的预算没有被财务部门批准,遇到这种情况,我也不能因为是自己 做的方案,就认为是财务部门的有意刁难,更不应该倚仗有领导的指示就肆意妄为,相反我应该保持一个平静的心 态,客观地去处理这件事情。

如果再三审视之后,确实没有找到相关的问题,我会和财务部门相关人员进行沟通,了解财务部门方面没有通 过的原因,认真听取他们的意见和建议,并把财务部门的意见和建议汇报给领导。我相信如果财务部门的意见合情 合理,领导一定会指示我按照财务部门的意见进行修改,方案也一定会通过。

Without bearing the consequences of the motor is not work at all. Because the axis of movement in any direction possible, while the electrical work required only for the rotation axis. Theoretically, the role of transmission can not be achieved, not only that, the bearings will also affect the transmission, in order to reduce the impact of high-speed shaft bearing lubrication must achieve good, and some lubricating bearing itself has called the pre-lubricated bearings, and Most of the bearings must be oil, the load at high speed, due to the friction will not only increase energy consumption, even more frightening is very easy to damage the bearings. The sliding friction into rolling friction is one-sided argument, as a kind of something called the sliding bearing. Rolling into size categories: (1) miniature bearings ---- nominal diameter size range of 26mm below the bearing; (2) small bearings ---- nominal diameter size range of 28-55mm bearings; (3 ) ---- small and medium sized bearing nominal diameter size range of 60-115mm bearings; (4) ---- large bearing nominal diameter size range of bearings for the 120-190mm (5) large bearing ---- nominal diameter size range of 200-430mm bearings; (6) ---- large bearing nominal diameter size range of 440-2000mm bearings. (7) significant bearing ---- nominal diameter size range of 2000mm above the bearings. The classification can bear the load direction can be divided into: ① radial bearings, also known as radial bearings, radial load. ② thrust bearing, also known as the thrust bearing, axial load. ③ radial thrust bearing, also known as radial thrust bearing to support radial load and axial load. Bearing friction by the different nature of the work can be divided into sliding friction bearings (the bearings) and the rolling friction bearings (the bearings) two broad categories. Angular contact ball bearings and rings contact angle is greater than the nominal 0 °, but less than 90 ° of the bearing. Can support radial load and axial load. Able to work at a high speed. The greater the contact angle, the higher the axial load capacity. High precision and high-speed bearings usually take the contact angle of 15 degrees. Axial force, the contact angle will increase. Single row angular contact ball bearings can withstand axial load in one direction, the radial load, will cause additional axial force. Shaft or housing, and can only limit the axial displacement in one direction. If pairs of double-installed, so a pair of bearing outer ring relative, that the wide end facing wide face, narrow side facing the narrow end. This can avoid additional axial force, but also in both directions so that the shaft or housing to limit axial clearance range. Spherical bearings are spherical and wide inner ring with locking pieces bearing to the heart. Used mainly for the simple case. Two roller bearing linear motion rolling direction in a relatively linear motion bearings. Ball bearings rolling body is a ball bearing. Deep groove ball bearings are a cross-section of each ring is about one-third of the circumference of the ball-type roller continuous groove ball bearings to the heart, for precision instruments, low noise motors, automobiles, motorcycles and general machinery , are the most widely used in machinery industry of a class of bearings. Simple structure, easy maintenance. Mainly used to bear radial load, but also can withstand a certain degree of axial load, when the radial bearing clearance increased with the performance of angular contact ball bearings can bear large axial load. This kind of bearing friction, high limiting speed, size range and diverse. Solid durability, versatility and low noise operation, can operate at high speed and easy to install. Sealed single row deep groove ball bearings and another design, you can not re-lubrication and no maintenance. Single row ball with gaps and double-row ball bearings, suitable for heavy working conditions. Thrust ball bearings Thrust ball rolling is rolling. Roller bearing is rolling bearing roller. Cylindrical roller bearings rolling body is cylindrical roller bearings to the heart, is a separation of bearings, installation and removal is very convenient. Divided into single row cylindrical roller bearings, double row and four columns. Installed in accordance with the rolling bearing different number of columns, cylindrical roller bearings can be divided into single row, double row and multi-row cylindrical roller bearings. One application is more cage row cylindrical roller bearings. In addition, single or double row full complement cylindrical roller and other structures of the cylindrical roller bearings. Single row cylindrical roller bearings under the ring ribs divided into N-type, NU type, NJ-type, NF-and NUP type. Cylindrical roller bearings under radial load capacity, according to the structure of ring wall can withstand a certain one-way or two-way axial load. NNU NN-and double row cylindrical roller bearings, compact structure, rigidity, load capacity, after the deformation under load, mostly for machine tool spindle bearing. FC, FCD, FCDP-type four-row cylindrical roller bearings can withstand greater radial load, and more for rolling mills and other heavy machinery. Cylindrical roller bearings are used in motors, machine tools, oil, mill machinery and all kinds of industrial material handling machinery. Tapered roller bearings rolling body is tapered roller bearings to the heart. Needle roller bearing is rolling bearing to the heart. Spherical roller bearings rolling body is convex or concave spherical roller bearings tone heart to heart. A convex spherical roller bearings, the outer ring raceway of a spherical shape; a concave roller bearings have a spherical shape of its inner ring raceway. Thrust roller bearings rolling body is thrust roller bearings. Thrust cylindrical roller bearings rolling body is thrust cylindrical roller bearings.
spherical roller bearings
thrust tapered roller bearings: rolling body is a tapered roller thrust bearing. Thrust needle roller bearings rolling body is thrust bearing. Spherical roller thrust bearings rolling body is convex or concave spherical roller thrust bearing aligning. A convex spherical roller bearing spherical roller ring-shaped, skechers outlet, with concave spherical roller bearing raceway ring axis spherical shape. Bearings Radial bearings with a seat combined with a component, in line with the axis parallel to the support bearing on the surface of the base plate mounting screws. Joint bearing surface of the spherical sliding contact, mainly used in swinging movement, tilting movement and rotation of the spherical plain bearings. Bearings of a bearing while the bearing structure of the two or more combination of rolling bearings. Such as needle roller and thrust cylindrical roller bearings, needle roller and thrust ball bearings, needle roller and angular contact ball bearings and so on.
plane bearing
Other Bearings: In addition to the above other than the structure of the bearing. Bearings: Plain bearings, regardless of inner and outer rings are not rolling, generally from wear-resistant materials. Commonly used in low-speed, heavy load and filling oil and difficult to maintain mechanical moving parts. Rolling mill bearing mill bearing is generally used to bear radial load, and the same size deep groove ball bearing, has a large radial load capacity, speed close to the deep groove ball bearings, but with the axis of such bearings Shell Hole higher, and allow the inner ring and outer ring axis inclination of the axis is very small (2 ° -4 °), two-axis tilt, such as beyond the limits of roller and ring raceway contact situation will be worse, serious of the load bearing capacity, reduce bearing life. Therefore, these bearings such as axial load needs to be installed in the role of host components, only the simultaneous use of other types of bearings to carry axial load of the premise, before use.
thrust roller bearings
General said bearings are rolling bearings (ball and roller bearing). Rolling is the operation of the shaft and the sliding friction between the axle seat to rolling friction, thus reducing the friction loss of a precision mechanical components. Generally bearing outer ring, inner ring, rolling body and cage components. Rolling easy maintenance, reliable, good starting performance, carrying capacity in the medium high speed. Compared with the sliding bearing, radial bearing large size, the less vibration, high speed, low life sounds great. Rolling bearings in to the heart (mainly radial force) are generally the inner ring, outer ring, rolling and rolling body cage 4 parts. In the journal on the inner sleeve along with the axis of rotation, the outer ring installed in the bearing hole. In the inner and outer peripheral were made within weeks on a rolling road. When the relative rotation of inner and outer rings, rolling the scroll, including the outer ring raceway, they are separated by a cage, to avoid rubbing against each other. Tight ring and thrust bearing live ring divided in two parts. Tight tight circle with the sleeve, live in the bearing seat bearing ring. Rings and rolling bodies are usually high strength, good wear resistance bearing steel, the surface hardness after quenching should reach HRC60 ~ 65. Cage is made more pressing with the soft steel, copper alloys can also be used bakelite cloth or plastic and other manufacturing. Bearing performance characteristics of the structure and thrust angular contact ball bearings Axial angular contact ball bearing contact angle of 60 ° is generally used in the thrust angular contact ball bearings are generally two-way thrust angular contact ball bearings, mainly used for precision machine tool spindles, usually with double row cylindrical roller bearings used in conjunction with, can withstand two-way axial load, with high accuracy and good rigidity, low temperature, high speed and easy assembly and disassembly. Deep groove ball bearings deep groove ball bearings in the structure of each ring with a cross-section of both the ball around the equatorial circumference is one-third of the continuous groove type raceway. Deep groove ball bearings are mainly used to bear radial load, but also can withstand a certain axial load. When the bearing radial clearance increases, with the nature of angular contact ball bearings, can withstand both directions alternating axial load. With the same size compared to other types of bearings, such bearings friction, high limiting speed, high precision, when a user selection of the preferred bearing type. Deep groove ball bearing structure is simple and easy to use, is the largest production volume, most widely used of a class of imported bearings. Thrust tapered roller bearings
thrust tapered roller bearings as the rolling body is tapered roller, rolling in the structure of the bus and washers are Raceway bus lines intersect at a point bearing axis , which can form the surface of pure rolling rolling, speed limit higher than the thrust cylindrical roller bearings. Features: Thrust tapered roller bearings can withstand axial load in one direction. Thrust tapered roller bearing type codes for the 90000 type. 4 bearings in the double row tapered roller bearing structure, performance characteristics
double row tapered roller bearings range, the maximum amount of 35,000 type, there is a double and two within the outer ring raceway circle, one between the two separated inner circle, changing the thickness of the spacer adjustable clearance. Such bearing radial load at the same time can withstand two-way axial load may be axial clearance in the bearing shaft and housing within the limits of the axial displacement. Tapered roller bearing structural characteristics. Tapered roller bearing type code is 30000, tapered roller bearings for the separation of bearings. Tapered roller bearings are mainly used to bear radial load mainly consisting of radial and axial load. Compared with the angular contact ball bearings, bearing capacity, low speed limit. Tapered roller bearings can withstand axial load in one direction, to limit the shaft or housing axial displacement in one direction. The early invention of the form of linear motion bearings, skid plate is a row in a row of wood placed. This technique may be traced back to when the construction of the Great Pyramid of Giza, though no clear evidence. Modern linear motion bearings are used in a working principle, but sometimes the ball instead of rollers. The first sliding and rolling bearings are made of wood. Ceramics, sapphire, or glass are also used, steel, copper, other metals, plastics (such as nylon, bakelite, teflon, and UHMWPE) have been widely used. From the heavy axle and spindle to precision watch parts, many occasions need to rotate the bearings. The simplest rotary bearing is the sleeve bearing, it is just a folder in the bush between the wheel and axle. This design was subsequently replaced rolling bearing is a cylindrical roller with a lot of the original bushing replacement, each rolling body is like a single wheel. First put into practical bearing cage with a clockmaker John Harry is worse than 1760 total time for the production of H3 invented. Nano Lake in Italy found a Roman vessel, found examples of early ball bearings. The wooden ball bearings are used to support the rotating desktop. The ship was built in BC 40 years. Leonardo da Vinci in around 1500 is said to have been of a description of ball bearings. The various factors bearing immature, there are a very important point is that collisions will occur between the ball, causing additional friction. But you can put the ball into a small cage to prevent this phenomenon. The 17th century, Galileo on the But in the following for a long time, install the bearings on the machine has not been realized. The first patent is on the ball channel Philip Vaughan Carmarthen acquired in 1794. In 1883, Friedrich Fischer proposed the use of suitable production machines grinding the same size and roundness of the ball and accurate claims. This laid the creation of an independent bearing industry base. In 1962, FAG has been modified and the trademark still in use today, and in 1979 became an integral part of the company. In 1895, Henry Timken designed the first tapered roller bearings, three years later obtained a patent and set up Timken Company. In 1907, SKF bearing factory Sven Lindqvist designed the first temperature and the modern self-aligning ball bearings. Note the use of mechanical parts, compared with the general, high precision roller bearing, so use accordingly should be careful. 1) Keep the bearing and its surroundings clean 2) when used carefully if the reckless use of a strong shock to the bearings will make in bearing injuries, indentation, fracture and other injuries. 3) Use the right tools 4) Note that to avoid rust bearings used in wet places, but also not to sweat stained, should wear gloves. 5) Users should be familiar with the bearing 6) used to develop job specifications bearing a, bearing the custody of b, and the surrounding bearing cleaning c, install the parts of the size and processing quality of the test d, installation e, f post-installation inspection , Demolition g, maintenance (regular inspection) h, shape ups skechers, additional bearing lubricant bearing the merits of how to identify strengths and weaknesses to identify the quality of equipment bearing quality, we usually from the following aspects: packaging under normal circumstances is clear , regular manufacturers have their own special brand of external packaging designers to design, production conditions and arrangements for clearance of the factory production of production, therefore, in terms of product packaging lines to the color should be very clear and unambiguous. Every word is clear stamp bearing products will be printed on the products bearing its brand body of words, labels and so on. Although the font is very small, but the formal product manufacturers have adopted the symbol printing technology, but without the heat pressure treatment is carried out before the word, so the fonts may be small, but a deep concave, very clear. And usually, the font of counterfeit products not only vague, because the rough printing technology, fonts, floating on the surface, some of them can be easily wiped off by hand or hand signs seriously. Whether there is complex set of bearing the body holding the left hand ring, right hand rotation to toggle coat, listening to whether the process of bearing operation miscellaneous ring. As most of the conditions behind the production of counterfeit products is entirely hand-workshop-type operations, bearing the body in the production process will inevitably be distracted by dust, sand, impurities in a class, so in time there will be rotating bearing ring or run complex phenomenon that is not smooth . This is to determine whether a product comes from strict production standards, and regular use of machine operation the key to brand manufacturers. Are there traces of oil the surface of the muddy muddy surface traces of oil if it necessary for us to buy imported bearings should be special attention. Because of the current anti-rust technology and advanced manufacturing countries there is a gap, so the rust on the bearing body can easily deal with traces of oil left behind a thick, sticky feeling when you touch the thick, viscous, and foreign bearings imported almost do not see any traces of rust preventive oil. According to insiders, in particular, careful people can import a particular bearing on the taste of smell, which is anti-rust oil flavor. The so-called bearing chamfer chamfer is uniform, that is, horizontal surface and vertical side of the junction, counterfeit products bearing the restrictions in production technology, in which the rougher edges of the site was unsatisfactory treatment, which we can easily identification. Were kept at the factory bearings coated with an appropriate amount of anti-rust oil and use rust-proof paper packaging, as long as the packaging is not damaged, the bearing quality will be guaranteed. But the long-term storage, to be below 65% humidity, the temperature is around 20 ℃ condition, stored in a shelf 30cm above the ground is appropriate. In addition, the storage place should avoid direct sunlight or touch the wall with the cold. Bearing Installation Precautions 1) The preparation of the bearing after bearing anti-rust treatment and be packaged, so do not open the package before installing Pro. In addition, anti-rust oil coating on the bearings with good lubrication performance, and for general purpose bearing grease bearings or filling can be used directly without cleaning. But for the instrument bearing or bearings for high-speed rotation, the application of clean oil clean oil will wash away the rust, then bearing easily rust, can not long be placed. 2) washing the test shaft and bearing housing and the housing, make sure to leave no scars or machining burr. Enclosure is absolutely prohibited abrasive (SiC, Al2O3, etc.) sand, chips and so on. Second, check the shaft and the shell size, shape and processing quality is consistent with the drawings. Bearings before installation in the shaft and housing inspection with the surface coating of various mechanical oil. Replace bearings bearings is a result of bearing types and vary with conditions. Because most multi-axis rotation, so the inner and outer ring can be used separately with the interference fit and clearance, while the outer ring rotates, the outer ring with the interference fit. (1) pressure to install the mounting pressure into the general use of press, but also can make use of bolts and nuts, when forced into the use of hand-loaded hammer. (2) sets of installation of hot bearings in oil heated to expand it and then install the shaft bearing thermal sets of methods can avoid being affected by unnecessary force, in a short time to complete the installation. Heating Note 1) general heating should not exceed 100 ℃. 2) does not allow contact with tank bottom bearing. Another hot set of installation can also use the induction heating device to heat expansion of the bearing and then installed in the shaft. Bearing periodic inspection or replacement of parts removal, you need to remove bearings. Shaft and bearing housing are usually almost always continue to use, the bearings tend to continue to use. Therefore, the structural design should take into account the removal of bearings, not to damage bearing, shaft, bearing housing and other parts, while also preparing the appropriate removal tools. Static with the ring removal, only to increase tension in the ring, and may not pull through the rolling ring. Maintenance of bearings is the bearing to maintain its full and proper performance of the long-term, regular maintenance must be a really good job (regular inspection). Through appropriate periodic inspection, so that early detection of failure, to prevent accidents in the first place, to increase productivity and economy is very important. 1, cleaning the bearings removed for inspection, first with photography and other methods to do the appearance record. In addition, to confirm the remaining amount of lubricant and lubricant samples, and then cleaning bearings. a, bearing wash to clean coarse and fine points for washing, and placed in the bottom of the container used in the metal grid. b, rough wash, brush used in oil grease or sticky materials such as clear. At this point if the rotating bearings in oil, pay attention to damage due to foreign bodies such as rolling surface. c, sperm washing, slowly rotating bearings in oil should be carefully carried out. Cleaning agents commonly used for the neutral non-water diesel or kerosene, is sometimes necessary to use warm lye. Regardless of what kind of cleaning agent used, must be kept clean filters regularly. Cleaned immediately after the anti-rust coating on the bearing oil or rust and grease. 2, check with the judge to determine whether the re-use the bearings removed, we should focus on checking the accuracy of its size, rotation accuracy, internal clearance, and with the surface, raceway, cage and ring. On the inspection results may be proficient with a bearing or bearings are used to judge. Criteria to determine the mechanical properties and importance under the inspection cycles, and vary. If the following injury, shape up skechers, the bearings may not re-use, must be replaced. 1) bearing parts of the faults and defects. 2) rolling raceway surface of the strip material. Bearing fault identification method is not by removing the check, you can identify or predict whether the failure of bearings in operation, to improve productivity and economy is very important. Identification of the main methods are as follows: identification by voice recognition using sound need to have a wealth of experience. Must be adequately trained to be able to identify voice and non-bearing bearing sound. Therefore, we should try to carry out this work by hand. Listening, or listening with a stick attached to the shell can be clearly heard the voice bearing. Temperature through the work of identification of the methods are of relatively recognition method is limited not by changes in the functioning of state occasions. To this end, the temperature must be continuously recorded. Failure, not only temperature, but also irregular changes. Recognition by the state of lubricant sampling and analysis of lubricants, whether through its pollution level, or metal powders mixed with foreign matter to judge. This method can not be observed near the bearings or large bearings are particularly effective. Bearing bearing packaging packaging packaging and packaging since the beginning. Bearing in the manufacture of finished and after passing inspection, the cleaning and anti-rust treatment, then put the package in order to achieve the water, moisture, dust, shock, maintaining the quality and precision bearings, and ease of use and sales. Bearing on three types of packaging by rust: ① short rust on the packaging: rust of 3 to 6 months for high-volume shipments to the same subscribers in the short term will be put into use in the bearings. By mutual agreement, to facilitate the use of the principle, the use of simple packaging. ② general corrosion of the packaging: anti-rust period of one year for general purpose bearings. ③ long rust on the packaging: anti-rust period of two years for special and precision bearings. Packaging materials bearing a polyethylene plastic tube (box), kraft paper, polyethylene and wrinkles plain paper, cartons, polyethylene or polyethylene plastic film, nylon fastening tape or plastic woven fastening tape, waterproof plastic with high strength , sacks, and so on. These materials are required to ensure the corrosion resistance of the material passing the test. ① miniature bearings inside the packing: 10 ~ 15 sets of bearings into a plastic tube, 5 to 10 per plastic tube put into a box (or bag, paper bag). ②, small bearings: bearing sets of polyethylene film, kraft paper or polyethylene for external use of paper for paper bag; several sets of bearings into a plastic tube (box); a single set of bearings with polyethylene film bag, collapse or Seal the bag and then into a box. ③ Large Bearing: polyethylene film or polyethylene single set of packaging paper, and then into a box; with polyethylene film bag, a single set packaging folding pocket, and then into a box; single package into a special plastic boxes; a single set of three bind up our wounds Packing: inner with polyethylene film or a composite tape, the middle fastening band, infiltration of plastic tape with a waterproof outer layer. ④ large bearings: a single set of three bind up our wounds packaging (ibid.); one by four bind up our wounds Packaging: packaged in the above three bind up our wounds, the outermost layer of linen with the then bind up our wounds. Diameter ≥ 150mm of the separable tapered roller bearings, in the packaging, the external component should be preceded by polyethylene film liner, or inner and outer components packaged separately. Diameter ≥ 150mm of interchangeable cylindrical roller bearings, complete packaging easy to knock because of injury, general internal and external components can be packaged separately. ① Double corrugated packaging boxes, each box of the total weight (gross weight) does not exceed 25kg, external tank strap tied; ② nail plate box (wooden box), skechers shoes online, each containing a total weight not exceeding 30kg, blue steel box tied topical; ③ Gaisu corrugated boxes, each containing a total weight not exceeding 25kg, packaged with a box tied with a plastic love. Will be packaged with the products bearing the load box, the box should be in plastic bags or plastic film liner; box if the gap required corrugated blocks, paper and other dry material to fill.

And data from the archaeological perspective, China's most ancient structure with a prototype of the modern rolling bearings, appeared in 221 ~ 207 BC (Qin Dynasty) in Yongji County, Shanxi Province, Xue this cliff village. After the founding of New China, particularly since the seventies of this century, a strong push in the reform and opening up, the bearing industry has entered a new period of rapid development of high quality. In the seventeenth century, the British design and manufacture of ball bearings C. Vallotton, and installed in the postal car, and the United Kingdom P. Worth trial made ball bearings of the patent. HR Hertz eighteenth century Germany made ball bearing contact stress on the paper. Build on the achievements in Hertz, shape up shoes, R. 施特里贝克 Germany, Sweden, Glenn A. Pam, who were a large number of experiments bearing on the development of design theory and contributed to the fatigue life calculation. Subsequently, the Russian NP Petrov apply Newton's law calculation of viscous friction bearings. Leo O. Renault UK discovery of a mathematical analysis of Reynolds equation is derived, from laying the hydrodynamic lubrication theory. Fifty years in the founding of the Chinese bearing industry has made remarkable achievements. Role
study in terms of its role should be to support the literal interpretation of the bearing axis is used, but only as part of its role, supporting its essence is the ability to bear radial load. Also be understood as it is for a fixed axis. Is fixed so that it can only achieve rotation axis, and control the axial and radial movement. Without bearing the consequences of the motor is not work at all. Because the axis of movement in any direction possible, while the electrical work required only for the rotation axis. Theoretically, the role of transmission can not be achieved, not only that, the bearings will also affect the transmission, in order to reduce the impact of high-speed shaft bearing lubrication must achieve good, and some lubricating bearing itself has called the pre-lubricated bearings, and Most of the bearings must be oil, the load at high speed, due to the friction will not only increase energy consumption, even more frightening is very easy to damage the bearings. The sliding friction into rolling friction is one-sided argument, as a kind of something called the sliding bearing. Rolling into size categories: (1) miniature bearings ---- nominal diameter size range of 26mm below the bearing; (2) small bearings ---- nominal diameter size range of 28-55mm bearings; (3 ) ---- small and medium sized bearing nominal diameter size range of 60-115mm bearings; (4) ---- large bearing nominal diameter size range of bearings for the 120-190mm (5) large bearing ---- nominal diameter size range of 200-430mm bearings; (6) ---- large bearing nominal diameter size range of 440-2000mm bearings. (7) significant bearing ---- nominal diameter size range of 2000mm above the bearings. The classification can bear the load direction can be divided into: ① radial bearings, also known as radial bearings, radial load. ② thrust bearing, also known as the thrust bearing, axial load. ③ radial thrust bearing, also known as radial thrust bearing to support radial load and axial load. Bearing friction by the different nature of the work can be divided into sliding friction bearings (the bearings) and the rolling friction bearings (the bearings) two broad categories. Angular contact ball bearings and rings contact angle is greater than the nominal 0 °, but less than 90 ° of the bearing. Can support radial load and axial load. Able to work at a high speed. The greater the contact angle, the higher the axial load capacity. High precision and high-speed bearings usually take the contact angle of 15 degrees. Axial force, the contact angle will increase. Single row angular contact ball bearings can withstand axial load in one direction, the radial load, will cause additional axial force. Shaft or housing, and can only limit the axial displacement in one direction. If pairs of double-installed, so a pair of bearing outer ring relative, that the wide end facing wide face, narrow side facing the narrow end. This can avoid additional axial force, but also in both directions so that the shaft or housing to limit axial clearance range. Spherical bearings are spherical and wide inner ring with locking pieces bearing to the heart. Used mainly for the simple case. Two roller bearing linear motion rolling direction in a relatively linear motion bearings. Ball bearings rolling body is a ball bearing. Deep groove ball bearings are a cross-section of each ring is about one-third of the circumference of the ball-type roller continuous groove ball bearings to the heart, for precision instruments, low noise motors, automobiles, motorcycles and general machinery , are the most widely used in machinery industry of a class of bearings. Simple structure, easy maintenance. Mainly used to bear radial load, but also can withstand a certain degree of axial load, when the radial bearing clearance increased with the performance of angular contact ball bearings can bear large axial load. This kind of bearing friction, high limiting speed, size range and diverse. Solid durability, versatility and low noise operation, can operate at high speed and easy to install. Sealed single row deep groove ball bearings and another design, you can not re-lubrication and no maintenance. Single row ball with gaps and double-row ball bearings, suitable for heavy working conditions. Thrust ball bearings Thrust ball rolling is rolling. Roller bearing is rolling bearing roller. Cylindrical roller bearings rolling body is cylindrical roller bearings to the heart, is a separation of bearings, installation and removal is very convenient. Divided into single row cylindrical roller bearings, double row and four columns. Installed in accordance with the rolling bearing different number of columns, cylindrical roller bearings can be divided into single row, double row and multi-row cylindrical roller bearings. One application is more cage row cylindrical roller bearings. In addition, single or double row full complement cylindrical roller and other structures of the cylindrical roller bearings. Single row cylindrical roller bearings under the ring ribs divided into N-type, NU type, NJ-type, NF-and NUP type. Cylindrical roller bearings under radial load capacity, according to the structure of ring wall can withstand a certain one-way or two-way axial load. NNU NN-and double row cylindrical roller bearings, compact structure, rigidity, load capacity, after the deformation under load, mostly for machine tool spindle bearing. FC, FCD, FCDP-type four-row cylindrical roller bearings can withstand greater radial load, and more for rolling mills and other heavy machinery. Cylindrical roller bearings are used in motors, machine tools, oil, mill machinery and all kinds of industrial material handling machinery. Tapered roller bearings rolling body is tapered roller bearings to the heart. Needle roller bearing is rolling bearing to the heart. Spherical roller bearings rolling body is convex or concave spherical roller bearings tone heart to heart. A convex spherical roller bearings, the outer ring raceway of a spherical shape; a concave roller bearings have a spherical shape of its inner ring raceway. Thrust roller bearings rolling body is thrust roller bearings. Thrust cylindrical roller bearings rolling body is thrust cylindrical roller bearings.
spherical roller bearings
thrust tapered roller bearings: rolling body is a tapered roller thrust bearing. Thrust needle roller bearings rolling body is thrust bearing. Spherical roller thrust bearings rolling body is convex or concave spherical roller thrust bearing aligning. A convex spherical roller bearing spherical roller ring-shaped, skechers outlet, with concave spherical roller bearing raceway ring axis spherical shape. Bearings Radial bearings with a seat combined with a component, in line with the axis parallel to the support bearing on the surface of the base plate mounting screws. Joint bearing surface of the spherical sliding contact, mainly used in swinging movement, tilting movement and rotation of the spherical plain bearings. Bearings of a bearing while the bearing structure of the two or more combination of rolling bearings. Such as needle roller and thrust cylindrical roller bearings, needle roller and thrust ball bearings, needle roller and angular contact ball bearings and so on.
plane bearing
Other Bearings: In addition to the above other than the structure of the bearing. Bearings: Plain bearings, regardless of inner and outer rings are not rolling, generally from wear-resistant materials. Commonly used in low-speed, heavy load and filling oil and difficult to maintain mechanical moving parts. Rolling mill bearing mill bearing is generally used to bear radial load, and the same size deep groove ball bearing, has a large radial load capacity, speed close to the deep groove ball bearings, but with the axis of such bearings Shell Hole higher, and allow the inner ring and outer ring axis inclination of the axis is very small (2 ° -4 °), two-axis tilt, such as beyond the limits of roller and ring raceway contact situation will be worse, serious of the load bearing capacity, reduce bearing life. Therefore, these bearings such as axial load needs to be installed in the role of host components, only the simultaneous use of other types of bearings to carry axial load of the premise, before use.
thrust roller bearings
General said bearings are rolling bearings (ball and roller bearing). Rolling is the operation of the shaft and the sliding friction between the axle seat to rolling friction, thus reducing the friction loss of a precision mechanical components. Generally bearing outer ring, inner ring, rolling body and cage components. Rolling easy maintenance, reliable, good starting performance, carrying capacity in the medium high speed. Compared with the sliding bearing, radial bearing large size, the less vibration, high speed, low life sounds great. Rolling bearings in to the heart (mainly radial force) are generally the inner ring, outer ring, rolling and rolling body cage 4 parts. In the journal on the inner sleeve along with the axis of rotation, the outer ring installed in the bearing hole. In the inner and outer peripheral were made within weeks on a rolling road. When the relative rotation of inner and outer rings, rolling the scroll, including the outer ring raceway, they are separated by a cage, to avoid rubbing against each other. Tight ring and thrust bearing live ring divided in two parts. Tight tight circle with the sleeve, live in the bearing seat bearing ring. Rings and rolling bodies are usually high strength, good wear resistance bearing steel, the surface hardness after quenching should reach HRC60 ~ 65. Cage is made more pressing with the soft steel, copper alloys can also be used bakelite cloth or plastic and other manufacturing. Bearing performance characteristics of the structure and thrust angular contact ball bearings Axial angular contact ball bearing contact angle of 60 ° is generally used in the thrust angular contact ball bearings are generally two-way thrust angular contact ball bearings, mainly used for precision machine tool spindles, usually with double row cylindrical roller bearings used in conjunction with, can withstand two-way axial load, with high accuracy and good rigidity, low temperature, high speed and easy assembly and disassembly. Deep groove ball bearings deep groove ball bearings in the structure of each ring with a cross-section of both the ball around the equatorial circumference is one-third of the continuous groove type raceway. Deep groove ball bearings are mainly used to bear radial load, but also can withstand a certain axial load. When the bearing radial clearance increases, with the nature of angular contact ball bearings, can withstand both directions alternating axial load. With the same size compared to other types of bearings, such bearings friction, high limiting speed, high precision, when a user selection of the preferred bearing type. Deep groove ball bearing structure is simple and easy to use, is the largest production volume, most widely used of a class of imported bearings. Thrust tapered roller bearings
thrust tapered roller bearings as the rolling body is tapered roller, rolling in the structure of the bus and washers are Raceway bus lines intersect at a point bearing axis , which can form the surface of pure rolling rolling, speed limit higher than the thrust cylindrical roller bearings. Features: Thrust tapered roller bearings can withstand axial load in one direction. Thrust tapered roller bearing type codes for the 90000 type. 4 bearings in the double row tapered roller bearing structure, performance characteristics
double row tapered roller bearings range, the maximum amount of 35,000 type, there is a double and two within the outer ring raceway circle, one between the two separated inner circle, changing the thickness of the spacer adjustable clearance. Such bearing radial load at the same time can withstand two-way axial load may be axial clearance in the bearing shaft and housing within the limits of the axial displacement. Tapered roller bearing structural characteristics. Tapered roller bearing type code is 30000, tapered roller bearings for the separation of bearings. Tapered roller bearings are mainly used to bear radial load mainly consisting of radial and axial load. Compared with the angular contact ball bearings, bearing capacity, low speed limit. Tapered roller bearings can withstand axial load in one direction, to limit the shaft or housing axial displacement in one direction. The early invention of the form of linear motion bearings, skid plate is a row in a row of wood placed. This technique may be traced back to when the construction of the Great Pyramid of Giza, though no clear evidence. Modern linear motion bearings are used in a working principle, but sometimes the ball instead of rollers. The first sliding and rolling bearings are made of wood. Ceramics, sapphire, or glass are also used, steel, copper, other metals, plastics (such as nylon, bakelite, teflon, and UHMWPE) have been widely used. From the heavy axle and spindle to precision watch parts, many occasions need to rotate the bearings. The simplest rotary bearing is the sleeve bearing, it is just a folder in the bush between the wheel and axle. This design was subsequently replaced rolling bearing is a cylindrical roller with a lot of the original bushing replacement, each rolling body is like a single wheel. First put into practical bearing cage with a clockmaker John Harry is worse than 1760 total time for the production of H3 invented. Nano Lake in Italy found a Roman vessel, found examples of early ball bearings. The wooden ball bearings are used to support the rotating desktop. The ship was built in BC 40 years. Leonardo da Vinci in around 1500 is said to have been of a description of ball bearings. The various factors bearing immature, there are a very important point is that collisions will occur between the ball, causing additional friction. But you can put the ball into a small cage to prevent this phenomenon. The 17th century, Galileo on the But in the following for a long time, install the bearings on the machine has not been realized. The first patent is on the ball channel Philip Vaughan Carmarthen acquired in 1794. In 1883, Friedrich Fischer proposed the use of suitable production machines grinding the same size and roundness of the ball and accurate claims. This laid the creation of an independent bearing industry base. In 1962, FAG has been modified and the trademark still in use today, and in 1979 became an integral part of the company. In 1895, Henry Timken designed the first tapered roller bearings, three years later obtained a patent and set up Timken Company. In 1907, SKF bearing factory Sven Lindqvist designed the first temperature and the modern self-aligning ball bearings. Note the use of mechanical parts, compared with the general, high precision roller bearing, so use accordingly should be careful. 1) Keep the bearing and its surroundings clean 2) when used carefully if the reckless use of a strong shock to the bearings will make in bearing injuries, indentation, fracture and other injuries. 3) Use the right tools 4) Note that to avoid rust bearings used in wet places, but also not to sweat stained, should wear gloves. 5) Users should be familiar with the bearing 6) used to develop job specifications bearing a, bearing the custody of b, and the surrounding bearing cleaning c, install the parts of the size and processing quality of the test d, installation e, f post-installation inspection , Demolition g, maintenance (regular inspection) h, shape ups skechers, additional bearing lubricant bearing the merits of how to identify strengths and weaknesses to identify the quality of equipment bearing quality, we usually from the following aspects: packaging under normal circumstances is clear , regular manufacturers have their own special brand of external packaging designers to design, production conditions and arrangements for clearance of the factory production of production, therefore, in terms of product packaging lines to the color should be very clear and unambiguous. Every word is clear stamp bearing products will be printed on the products bearing its brand body of words, labels and so on. Although the font is very small, but the formal product manufacturers have adopted the symbol printing technology, but without the heat pressure treatment is carried out before the word, so the fonts may be small, but a deep concave, very clear. And usually, the font of counterfeit products not only vague, because the rough printing technology, fonts, floating on the surface, some of them can be easily wiped off by hand or hand signs seriously. Whether there is complex set of bearing the body holding the left hand ring, right hand rotation to toggle coat, listening to whether the process of bearing operation miscellaneous ring. As most of the conditions behind the production of counterfeit products is entirely hand-workshop-type operations, bearing the body in the production process will inevitably be distracted by dust, sand, impurities in a class, so in time there will be rotating bearing ring or run complex phenomenon that is not smooth . This is to determine whether a product comes from strict production standards, and regular use of machine operation the key to brand manufacturers. Are there traces of oil the surface of the muddy muddy surface traces of oil if it necessary for us to buy imported bearings should be special attention. Because of the current anti-rust technology and advanced manufacturing countries there is a gap, so the rust on the bearing body can easily deal with traces of oil left behind a thick, sticky feeling when you touch the thick, viscous, and foreign bearings imported almost do not see any traces of rust preventive oil. According to insiders, in particular, careful people can import a particular bearing on the taste of smell, which is anti-rust oil flavor. The so-called bearing chamfer chamfer is uniform, that is, horizontal surface and vertical side of the junction, counterfeit products bearing the restrictions in production technology, in which the rougher edges of the site was unsatisfactory treatment, which we can easily identification. Were kept at the factory bearings coated with an appropriate amount of anti-rust oil and use rust-proof paper packaging, as long as the packaging is not damaged, the bearing quality will be guaranteed. But the long-term storage, to be below 65% humidity, the temperature is around 20 ℃ condition, stored in a shelf 30cm above the ground is appropriate. In addition, the storage place should avoid direct sunlight or touch the wall with the cold. Bearing Installation Precautions 1) The preparation of the bearing after bearing anti-rust treatment and be packaged, so do not open the package before installing Pro. In addition, anti-rust oil coating on the bearings with good lubrication performance, and for general purpose bearing grease bearings or filling can be used directly without cleaning. But for the instrument bearing or bearings for high-speed rotation, the application of clean oil clean oil will wash away the rust, then bearing easily rust, can not long be placed. 2) washing the test shaft and bearing housing and the housing, make sure to leave no scars or machining burr. Enclosure is absolutely prohibited abrasive (SiC, Al2O3, etc.) sand, chips and so on. Second, check the shaft and the shell size, shape and processing quality is consistent with the drawings. Bearings before installation in the shaft and housing inspection with the surface coating of various mechanical oil. Replace bearings bearings is a result of bearing types and vary with conditions. Because most multi-axis rotation, so the inner and outer ring can be used separately with the interference fit and clearance, while the outer ring rotates, the outer ring with the interference fit. (1) pressure to install the mounting pressure into the general use of press, but also can make use of bolts and nuts, when forced into the use of hand-loaded hammer. (2) sets of installation of hot bearings in oil heated to expand it and then install the shaft bearing thermal sets of methods can avoid being affected by unnecessary force, in a short time to complete the installation. Heating Note 1) general heating should not exceed 100 ℃. 2) does not allow contact with tank bottom bearing. Another hot set of installation can also use the induction heating device to heat expansion of the bearing and then installed in the shaft. Bearing periodic inspection or replacement of parts removal, you need to remove bearings. Shaft and bearing housing are usually almost always continue to use, the bearings tend to continue to use. Therefore, the structural design should take into account the removal of bearings, not to damage bearing, shaft, bearing housing and other parts, while also preparing the appropriate removal tools. Static with the ring removal, only to increase tension in the ring, and may not pull through the rolling ring. Maintenance of bearings is the bearing to maintain its full and proper performance of the long-term, regular maintenance must be a really good job (regular inspection). Through appropriate periodic inspection, so that early detection of failure, to prevent accidents in the first place, to increase productivity and economy is very important. 1, cleaning the bearings removed for inspection, first with photography and other methods to do the appearance record. In addition, to confirm the remaining amount of lubricant and lubricant samples, and then cleaning bearings. a, bearing wash to clean coarse and fine points for washing, and placed in the bottom of the container used in the metal grid. b, rough wash, brush used in oil grease or sticky materials such as clear. At this point if the rotating bearings in oil, pay attention to damage due to foreign bodies such as rolling surface. c, sperm washing, slowly rotating bearings in oil should be carefully carried out. Cleaning agents commonly used for the neutral non-water diesel or kerosene, is sometimes necessary to use warm lye. Regardless of what kind of cleaning agent used, must be kept clean filters regularly. Cleaned immediately after the anti-rust coating on the bearing oil or rust and grease. 2, check with the judge to determine whether the re-use the bearings removed, we should focus on checking the accuracy of its size, rotation accuracy, internal clearance, and with the surface, raceway, cage and ring. On the inspection results may be proficient with a bearing or bearings are used to judge. Criteria to determine the mechanical properties and importance under the inspection cycles, and vary. If the following injury, shape up skechers, the bearings may not re-use, must be replaced. 1) bearing parts of the faults and defects. 2) rolling raceway surface of the strip material. Bearing fault identification method is not by removing the check, you can identify or predict whether the failure of bearings in operation, to improve productivity and economy is very important. Identification of the main methods are as follows: identification by voice recognition using sound need to have a wealth of experience. Must be adequately trained to be able to identify voice and non-bearing bearing sound. Therefore, we should try to carry out this work by hand. Listening, or listening with a stick attached to the shell can be clearly heard the voice bearing. Temperature through the work of identification of the methods are of relatively recognition method is limited not by changes in the functioning of state occasions. To this end, the temperature must be continuously recorded. Failure, not only temperature, but also irregular changes. Recognition by the state of lubricant sampling and analysis of lubricants, whether through its pollution level, or metal powders mixed with foreign matter to judge. This method can not be observed near the bearings or large bearings are particularly effective. Bearing bearing packaging packaging packaging and packaging since the beginning. Bearing in the manufacture of finished and after passing inspection, the cleaning and anti-rust treatment, then put the package in order to achieve the water, moisture, dust, shock, maintaining the quality and precision bearings, and ease of use and sales. Bearing on three types of packaging by rust: ① short rust on the packaging: rust of 3 to 6 months for high-volume shipments to the same subscribers in the short term will be put into use in the bearings. By mutual agreement, to facilitate the use of the principle, the use of simple packaging. ② general corrosion of the packaging: anti-rust period of one year for general purpose bearings. ③ long rust on the packaging: anti-rust period of two years for special and precision bearings. Packaging materials bearing a polyethylene plastic tube (box), kraft paper, polyethylene and wrinkles plain paper, cartons, polyethylene or polyethylene plastic film, nylon fastening tape or plastic woven fastening tape, waterproof plastic with high strength , sacks, and so on. These materials are required to ensure the corrosion resistance of the material passing the test. ① miniature bearings inside the packing: 10 ~ 15 sets of bearings into a plastic tube, 5 to 10 per plastic tube put into a box (or bag, paper bag). ②, small bearings: bearing sets of polyethylene film, kraft paper or polyethylene for external use of paper for paper bag; several sets of bearings into a plastic tube (box); a single set of bearings with polyethylene film bag, collapse or Seal the bag and then into a box. ③ Large Bearing: polyethylene film or polyethylene single set of packaging paper, and then into a box; with polyethylene film bag, a single set packaging folding pocket, and then into a box; single package into a special plastic boxes; a single set of three bind up our wounds Packing: inner with polyethylene film or a composite tape, the middle fastening band, infiltration of plastic tape with a waterproof outer layer. ④ large bearings: a single set of three bind up our wounds packaging (ibid.); one by four bind up our wounds Packaging: packaged in the above three bind up our wounds, the outermost layer of linen with the then bind up our wounds. Diameter ≥ 150mm of the separable tapered roller bearings, in the packaging, the external component should be preceded by polyethylene film liner, or inner and outer components packaged separately. Diameter ≥ 150mm of interchangeable cylindrical roller bearings, complete packaging easy to knock because of injury, general internal and external components can be packaged separately. ① Double corrugated packaging boxes, each box of the total weight (gross weight) does not exceed 25kg, external tank strap tied; ② nail plate box (wooden box), skechers shoes online, each containing a total weight not exceeding 30kg, blue steel box tied topical; ③ Gaisu corrugated boxes, each containing a total weight not exceeding 25kg, packaged with a box tied with a plastic love. Will be packaged with the products bearing the load box, the box should be in plastic bags or plastic film liner; box if the gap required corrugated blocks, paper and other dry material to fill.
