摘要：
It is necessary to reduce fretting wear of railway axle journal bearings caused by very slight relative slips between the contact surfaces of the inner ring and the backing ring. This paper proposes a backing ring with grooves in the circumferential direction on its oil seal sliding surface to obtain even contact pressure distributions in the radial direction between them. Results of a rotation test on a full‐scale railway axle bearing using the proposed backing ring showed that this proposal is effective in suppressing fretting wear. © 2023 Ken-yusha Inc..
