Abstract
Abstract
Aiming at the fatigue life of bearing in oscillatory applications, through the analysis of the equivalent load of each part of bearing in oscillatory applications, the equivalent load of each part is calculated. Taking the 7005 angular contact ball bearing as the research object, the stress changes of each component are obtained through the transient dynamic analysis of the model, the fatigue of the bearing is analyzed based on the stress damage theory, and the damage and fatigue life of the bearing is obtained. The results show that the rolling element of the 7005 bearings is the weak part of failure under the given working condition, and it is more reasonable to design the service life of the shafting structure with an equivalent load of the rolling element, which provides reference measures for improving the service life of the oscillated bearing.
