摘　　要：基于ADAMS建立了角接触球轴承参数化模型,借助于ADAMS中的碰撞函数,在综合分析碰撞参数物理意义的基础上,对角接触球轴承进行动力学分析,研究保持架兜孔间隙、引导间隙及轴向载荷对其运行稳定性的影响。通过分形理论中的计盒维数,对保持架质心轨迹进行量化评定,以确定最佳的保持架结构参数。The parameterized model for angular contact ball bearings is developed based on ADAMS. With the help of impact function in ADAMS and based on the integrated analysis of the physical interpretation of impact parameters, the dynamics of angular contact ball bearings is analyzed, and the effects of the axial load, pocket clearance and guide clearance of the cages on the cage stability are investigated. The cage mass center motions are quantitative evaluated by the box - counting dimension of fractal theory and finally the best structural parameter of the cages is obtained.
