Evaluation of the fatigue fife of the deep groove ball bearing under radial and moment loads

摘要

Misalignment induces radial and moment loads on the bearing,and the relationship between misalignment and moment was obtained.And it was found that radial load was not sensitive to the relationship between both.The analysis of the laod distributions between balls and reaceways,and the prediction of fatigue life of deep groove ball bearing under radial and moment loads were carried out.When the moment load is dominant,these affect more severe on the fatigue life.
