摘　　要：轴承打滑易造成轴承的早期失效,传统的轴承打滑分析方法认为轴承参数是确定的,而在实际工况中轴承参数具有随机性,从而造成较大的分析误差.针对此问题,考虑随机因素的影响,提出一个角接触球轴承打滑行为的可靠性分析模型.基于轴承拟静力学分析和试验打滑判据得到轴承的打滑临界平面,以轴承是否打滑为判别条件,建立轴承打滑的极限状态方程,采用Kriging方法进行了可靠性灵敏度分析,评价轴承各参数对打滑现象的影响程度.研究结果表明:轴承滚动体直径的变化对轴承打滑现象影响最大,轴承内、外圈沟道直径和曲率半径的变化对其影响次之,接触角的变化对其影响较小.该研究为防止轴承打滑引起早期失效提供理论依据.Bearing skidding is likely to cause early failure of the bearings.Traditional methods of bearing skidding analysis claim that the bearing parameters are determined,but they are random in actual working conditions,which may cause larger analysis errors.In order to solve this problem,a reliability analysis model of angular contact ball bearing skidding which takes into account the influence of random factors is proposed.According to the quasi-static analysis of rolling bearings and the criterion of Hirano for bearing skidding,the critical surface of skidding is given,and the limit-state equation of bearing skidding is established based on whether the bearing is skidding or not.The reliability sensitivity analysis is carried out by using Kriging method to evaluate the influence of bearing parameters on bearing skidding.The research results show that the change of ball diameters has the most impact on the bearing skidding,then the raceway diameter and groove curvature radius of the inner and outer raceway take the second place,and the contact angle is the least.The research results may provide the theoretical basis for reducing or avoiding ball bearing skidding.
