摘　　要：基于球笼式等速万向节钢球的受力模型,推导了一个钢球在星形套内沟道和钟形壳外沟道内运动时,沟道对钢球的周向力、沟道对钢球的法向接触力、保持架窗口对钢球的法向接触力的表达式。在此基础上,基于Herzt接触理论,对上述受力进行了Adams动力学验证。结果表明:仿真结果和理论计算基本吻合,七沟道球笼式等速万向节的周向力、法向接触力、钢球与星形套的摩擦力、与保持架的摩擦力均小于六沟道,并且随着摆角的变化而变化。Based on the force model of the ball in the cage type constant velocity universal joint,the expressions of the circumferential force of the groove on the steel ball,the normal contact force of the channel to the steel ball and the normal contact force of the cage window to the steel ball are deduced when the steel ball moves in the inner groove and the bell shaped outer channel of the star sleeve.On this basis,based on the Herzt contact theory,the above force is verified by Adams dynamics.The results show that the simulation results are basically consistent with the theoretical calculation.The circumferential force,the normal contact force,the friction force of the steel ball and the star sleeve and the friction force of the seven channel cage type constant velocity universal joint are less than that of the six channel,and they change with the change of the swinging angle.
