Study on the Wear Characteristics of Angular Contact Ball Bearings

Abstract

For the wear of rolling bearings, this paper establishes a wear model of angular contact ball bearings based on the proposed static mechanics of rolling bearings, kinematics of rolling bearings and Archard's wear theory, studies the wear of bearings, and analyses the effects of rotational speed, load and structural parameters on the wear of bearings. The results show that: the inner ring of the bearing is uniformly worn and the depth of wear is larger than the outer ring; the depth of wear of the inner ring of the bearing increases with the increase of rotational speed, the load has a certain effect on the depth of wear, the depth of wear increases with the increase of axial load; the structural parameters of the bearings have a certain effect on the wear, the depth of wear of the inner ring decreases with the increase of the radius of curvature of the internal grooves, the radius of curvature of the internal grooves has a small effect on the outer ring wear, and the selection of appropriate structural parameters can effectively reduce the wear of the bearings, the wear of the bearings can be reduced. Selection of appropriate structural parameters can effectively attenuate the wear.
