Abstract

In this paper, for double row angular contact ball bearing, a five-degrees-of-freedom bearing analysis model based on quasi-statics is proposed. This model is used to study the influence of structural parameters and service conditions on the tilt angle and limit tilt angle of the bearing. The results show that the radial clearance will increase the ultimate tilt angle. The coincidence degree between the roller and the inner raceway will reduce the ultimate tilt angle, but the coincidence degree between the roller and the outer raceway has the opposite effect. The increase in the external load of the bearing will increase the tilt angle. The moment load has the greatest effect on the tilt angle. The rotation speed of the bearing has no effect on the tilt angle. The coincidence degree between the roller and the raceway will reduce the tilt angle; furthermore, the influence of the coincidence degree between roller and different ring on the tilt angle is also different when different rings are fixed. The tilt angle will decrease with the increase of the initial contact angle, and this effect is more and more obvious. The fixation of different ring has no effect on this influence.

结构参数和使用条件对双列角接触球轴承倾斜角的影响

针对双列角接触球轴承，提出了基于准静力学的五自由度轴承分析模型。该模型用于研究结构参数和使用条件对轴承倾斜角和极限倾斜角的影响。结果表明，径向间隙增大了极限倾角。滚轮与内滚道的重合程度会减小滚轮的极限倾斜角，而滚轮与外滚道的重合程度则相反。轴承外载荷的增加将增加倾斜角。弯矩载荷对倾角的影响最大。轴承的转速对倾斜角度没有影响。滚轮与滚道的重合程度会减小滚轮的倾斜角;此外，在固定不同环的情况下，滚子与不同环的配合程度对倾斜角的影响也不同。随着初始接触角的增大，倾斜角会减小，且这种影响越来越明显。不同环的固定对这种影响没有影响。
