Vibration of Separators in High-Speed Ball Bearings
-
摘要: 在考虑弹性流体动力润滑的基础上,提出了一个高速球轴承保持架振动响应模型,建立了保持架动力学方程.应用这个模型对某型航空发动机的主轴承保持架进行了仿真计算.计算结果的分析表明,保持架疲劳断裂的重要原因是高阶共振和过渡过程的冲击作用.Abstract: Dynamics equations are established respectively for separators and balls of a high-speed ball bearing on the base of elector-hydro-dynamic lubrication. A model is proposed to describe the response of the separator, which was proved reasonable and reached a desirable results. On the above basis, it is suggested that high-scale vibration and impact during transition may be the main factors responsible for the fatigue fracture of the separator.
