摘要： 本文中根据Archard磨损理论,对球笼式等速万向节内部进行了磨损分析。通过求出球笼式等速万向节钢球在沟道内的瞬时角速度和沟道与钢球接触点的瞬时角速度,分析钢球在沟道内的瞬时滑滚情况,以此判断钢球在沟道内的滑滚移动状态,从而求出钢球与星形套、钟形壳之间的摩擦力随输入端转角、轴间摆角的变化规律。几何推导及仿真的结果同时得出了球笼式等速万向节的磨损类型为疲劳磨损以及七沟道的万向节内磨损情况明显好于六沟道的结论。文中同时还推导出了体积磨损率与输入轴转速、转角和轴间摆角等的具体关系式,为后续研究奠定了重要的理论基础。

Abstract: According to Archard’s wear theory, the internal wear analysis of the Rzeppa constant velocity universal joint is carried out. By calculating the instantaneous angular velocity of the ball in the groove and the contact point between the groove and the ball, the instantaneous sliding and rolling of the ball in the groove are analyzed. The sliding and rolling state of the ball in the groove is judged, and the law of the change of friction force between the ball and the star sleeve and the bell shell with the input end rotation angle and axe swing angle is obtained. The results of geometric derivation and computer simulation also show that the wear type of ball cage constant velocity universal joint is fatigue wear and the wear condition in seven-channel universal joint is better than that in six-channel joint. At the same time, the specific relationship between volume wear rate and input shaft speed, rotation angle and swing angle is deduced, which lays an important theoretical foundation for the follow-up study
