摘要: 滚道剥落是滚动轴承的一种重要失效形式。本文以N205EM圆柱滚子轴承为对象，建立其有限元动力学分析模型，研究单处及多处滚道剥落对轴承动态特性的影响规律。研究结果表明：滚道剥落的存在会降低轴承的振动稳定性和传动精度；滚道剥落位置的增加，将使轴承产生卡死现象的机率上升；滚道剥落位置越多，轴承的振动稳定性和传动精度越差；在剥落位置达到3处以前，应对轴承进行及时更换。研究结论可以为滚动轴承的选取和设计提供参考。
Abstract: Raceway spalling is an important failure form for rolling bearings. In this paper, the N205EM cy-lindrical roller bearing is used as the object to establish the finite element dynamics analysis model, and the influence of single and multiple raceway spalling on the dynamic characteristics of bearing is studied. The results show that the existence of raceway spalling will reduce the vibration stability and transmission accuracy of bearing; an increase in raceway spalling number will increase the probability of bearing jamming; the more the number of raceway spalling, the worse the vibration stability and transmission accuracy; bearing should be replaced in time before spalling number reaches three. The research conclusion can provide reference for rolling bearing selection and design.
