Linear Rolling Guides EHL analysis


Run off of transmission in which the Xi state, the friction characteristics of transmission parts for the estimated life as well as the rolling , if properly lubricated measures, the processing method is correct, it is possible that in the whole film EHL condition, which is maintaining rail deputy high motion accuracy and long service life extension is beneficial. (3) the impact on the thickness of the speed factor is obvious, under certain conditions, the higher the speed, the thicker the film, while the structural parameters, the greater the value of the thinner film, but,MBTシューズ 販売店, in common case it changed little, the impact of changes in its thickness is generally less than 5%. (4) According to the film thickness and the relationship between stiffness and load, high load in the expense of small thickness may be cut very high degree, which requires a high degree of cut when the system is a better choice.

In addition to the active role of torque on the Ll pieces, the rest had no external force on each component. Based active components (crank) 1 to = 200r/mln constant speed rotation, the radius of solving two different components of the output gap (the pendulum) and the pivot in the angular velocity of the reaction. Numerical solution using Runge-Kutta method (13), resulting in the angular velocity of the pendulum shown in Figure 3, which Figure A is a small gap (o.02cm) case, Figure b is a large gap (o.08cm) when situation can be seen from the figure, when the deputy campaign in the gap when the pendulum angular velocity along the ideal curve obtained under the angular velocity fluctuations. Xin small gap, the higher frequency fluctuations, and fluctuations in the amplitude decreases, the gap gradually approaches zero, the infinite frequency of the pendulum angular velocity increased volatility, volatility tends to zero, that tends to the theoretical curve. Figure 4 shows the pivot point in contact with the reaction force at the crank angle curve. Figure a, b, respectively, reflecting the gap is too small gap and the situation can be seen from the figure, the gap frequency of large fluctuations in hours of reaction, surface in the large gap, the general reaction wave frequency small amplitude large. Also from the figure can be drawn: In some locations, the reaction is negative. Taking into account the pivot axis and can not bear the tension between, so the reaction is negative, that the axis pin and sleeve will be separated. Can be negative as the reaction force elements to determine whether there is motion pair separation and the impact of the criteria from the study results, we may see the two separated for a short time, so continuous contact model has a good effect also,Beats By Dre Studio, with the gap size changes, the number and location of the separation also change accordingly.
