Failure Progression Monitoring of Grease Lubricated Tapered Roller Bearings by Wear Debris Analysis.

摘要

This report documents a study of the wear debris characteristics of grease-lubricated tapered roller bearings. Bearings were operated to failure in a grease-lubricated environment. Samples of grease were periodically taken and Ferrographically analyzed. The analysis was correlated to actual bearing condition through periodic inspection. Particle morphologies were indicative of bearing distress while quantitative data exhibited no characteristics patterns. (Author)
