Abstract

A quasi-dynamic method is proposed to evaluate the characteristics of ball bearings including pressure distribution over the contact area between the ball and the raceway; sliding velocity distribution and lubrication parameters. Based on the Archard wear equation, the permissible wear extent is confirmed, and a mathematical model for wear-life analysis is then presented for 6000 deep groove ball bearings with the axial loads. The effects of axial loads, rotating speed and structural parameters on wear characteristics of bearings are analyzed, and some conclusions are drawn. Based on the proposed mathematical model, wear-life of a bearing decreases with the increase of the axial load. As the rotational speed of the inner ring increases, the wear-life of the bearing decreases accordingly. The wear-life of the bearing exhibits nearly-linear increment as the groove curvature of the inner ring increases.
