【摘要】 分析了高速滚子轴承中保持架的复杂受力,建立了保持架的碰撞动力学模型和保持架的动力学运动方程。在轴承整体稳定的拟动力学解的基础上,利用四阶Runge-Kutta积分方法计算了保持架质心随时间的变化规律。同时举例分析了轴承结构参数对保持架运动稳定性的影响。更多还原

【Abstract】 The complex forces on cage of the high - speed cylindrical roller bearing has been analyzed, and the collision dynamics model and dynamics motion equation of the cage have been set up. On the base of quasi - dynamics solution of stable state of the bearing, the instantaneous locations of cage mass center has been found by 4 rank Runge - Kutta integral method. The effect of the bearing structure parameters on cage motion stability has been analyzed.更多还原
