The purpose of this study is to investigate the dynamic behavior of the ball bearing with cage broken.,By analyzing the complicated relationship and interactions among the ball bearing elements, the dynamic modelling of the ball bearing with broken cage was established, and the dynamic simulations were conducted by solving the ball bearing dynamic equations using varying-step Runge–Kutta integration.,The computational results show that there is considerable distinguishment in the dynamic characteristics between the normal cage and the broken cage of the bears. The broken cage makes the trajectory of the cage erratic, and the vibration amplitude is much bigger than that of the normal cage, which makes the motion of the cage unstable. When one of the cage lintels breaks up, the two adjacent balls will collide with each other; what is worse, this may make the balls crush because of the high amplitude of the collision force. The broken cage makes the cage-race interaction force much larger than that of the normal cage, which could promote the guiding ring and quicken the cage wear-failure.,This study can provide important ideas for the fault identification of the ball bearing with cage broken.,The peer review history for this article is available at: https://publons.com/publon/10.1108/ILT-01-2020-0042/

保持架破壁球轴承的动态特性研究

本研究的目的是研究保持架断裂球轴承的动力学行为。通过分析球轴承元件之间复杂的关系和相互作用，建立了保持架断裂球轴承的动力学建模，并进行了动力学仿真。通过使用变步长 Runge-Kutta 积分求解球轴承动力学方程进行了计算。计算结果表明，熊的正常保持架和断裂保持架之间的动态特性有相当大的区别。破碎的笼子使笼子的运动轨迹不稳定，振动幅度比普通笼子大很多，使笼子运动不稳定。当其中一个笼门楣断裂时，相邻的两个球会相互碰撞；更糟糕的是，由于碰撞力的高振幅，这可能会使球破碎。断裂的保持架使保持架-滚道相互作用力远大于普通保持架，可促进导向环，加速保持架磨损失效。,该研究可为带保持架球轴承的故障识别提供重要思路坏了，这篇文章的同行评审历史可以在：https://publons.com/publon/10.1108/ILT-01-2020-0042/
