A dynamic contact wear model of ball bearings consisting of wear degree and position distribution is proposed by integrating the developed contact wear model, multi-body dynamics and raceway waviness or ball diameter differences. Subsequently, the dynamic wear characteristics, not only for the ideal bearing under different axial and radial loads, but also for the bearing with above defects are analysed. The influences of load, typical waviness orders and amplitude on the wear of each ball against both raceways are evaluated and qualitatively validated. Finally, the dynamic characteristics of ball bearings with one ball larger are discussed, and then vibration frequency and wear rates distinction are verified by the experiment with working-surface roughness measurement as a way for wear rate assessment.

无分布缺陷或有分布缺陷的球轴承动态接触磨损模型

综合所建立的接触磨损模型、多体动力学和滚道波纹度或球径差异，提出了一种由磨损程度和位置分布组成的球轴承动态接触磨损模型。随后，不仅对理想轴承在不同轴向和径向载荷下的动态磨损特性进行了分析，而且对具有上述缺陷的轴承进行了动态磨损特性分析。评估和定性验证负载、典型波纹阶数和振幅对每个滚珠在两个滚道上的磨损的影响。最后，讨论了较大一球的球轴承的动态特性，然后通过将工作表面粗糙度测量作为磨损率评估方法的实验，验证了振动频率和磨损率的区别。
