- Abstract
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.
