摘　　要：发动机主轴轴承失效的主要形式之一就是保持架的损坏,而保持架损坏的原因主要是保持架的磨损及滚动体对保持架的冲击。根据高速滚子轴承中保持架的受力分析,对保持架的结构进行了改进,从而改善了轴承润滑及保持架运动的稳定性,提高了保持架的安全性和可靠性。One of the main reasons of the failure on main shaft bearing of aviation engine is the damage of cage. The abrasion of the cage and the impact that the rolling elements to the cage cause the cage damage. According to stressed analysis of cage and some problems of high speed roller bearing, the structure of cage is improved, then the lubrication of bearing and the stability of cage are improved, safety and reliability of cage are increased.
