摘　　要：对发动机主轴承保持架的动力与冲击载荷进行分析研究 ,根据保持架的运动特点 ,并针对保持架的碰撞问题作详细讨论 ,建立了它的冲击振动模型。分析了此碰撞与其它因素的关系及影响。In this paper, dynamic load, together with impact load, of the cage in the main roller bearing of an engine is considered. Based on dynamic characteristics and colliding mechanism, colliding vibration model is established. Then colliding vibration problem is solved to show the interaction between the cage and the other parts of the bearing.
