Research on Manufacturing Method of Surface Integrity of Large-size Bearing Raceway with Excellent Service Performance

Abstract

The quality of the bearing ring raceway surface layer directly affects its service performance. Surface defects such as micro-cracks, high tensile stress state and tissue damage caused by improper processing methods seriously damage the surface integrity of the work-piece and reduce bearing fatigue strength or fatigue life. In this paper, through the theoretical analysis and surface integrity manufacturing technology of abrasive flow polishing for high service performance bearings, the basic theoretical method for improving the surface quality of large bearings is established. This achieves the performance-driven manufacturing requirements required for high service performance bearing parts and innovative manufacturing methods for improving the quality of the bearing ring raceway surface.
