摘　　要：针对摆动球轴承工作过程中保持架早期失效问题,基于滚动轴承动力学理论,建立摆动工况下球轴承的动力学分析模型。采用Gear stiff变步长积分算法求解该模型,分析轴承工况参数、润滑剂拖动系数和保持架兜孔间隙对钢球与保持架瞬时碰撞行为的影响。结果表明:摆动工况下钢球与保持架的碰撞力远大于恒速下钢球与保持架的碰撞力;承载区钢球与保持架的碰撞力最大,不断进出承载区钢球与保持架的碰撞力次之,非承载区钢球与保持架的碰撞力最小;较大的保持架兜孔间隙将增加钢球与保持架的碰撞力;减小轴承稳定速度、径向载荷、增加轴承变速时间以及使用低黏度的润滑剂均有利于减小钢球与保持架的碰撞。For the failure of cage in ball bearing under the oscillating condition,a dynamic analysis model of oscillating ball bearing is established based on the dynamics theory of rolling bearing,and solved by the Gear stiff(GSTIFF) integer algorithm with variable steps.The effects of bearing operating parameters,lubricant traction coefficient and cage pocket clearance on the collision behavior between cage and ball are investigated.The results show that the collision force between ball and cage under the oscillating condition is obviously larger than that at constant speed.The collision force between ball and cage in the loading area is the largest,their collision force in the non-loading area is larger,and the collision force in and out of the loading area is the smallest.The collision force between cage and ball increases with increase in cage pocket clearance.The reduction in stability speed and radial load of bearing,the increase in shifting time and the use of low viscosity lubricant are beneficial to reduce the collision force between ball and cage.
