Sound and Vibration Research of Rolling Bearings in Japan

Abstract

This article deals with the progress of the sound and vibration research of rolling bearings in Japan. The literature mainly cited is written in Japanese. The focus in sound research is the early research, characteristics and generating mechanism of ball bearings, cage sound, squeak in cylindrical roller bearings, sound of defective bearings, contamination noise and sound life. In the vibration research, the early research, rolling element (ball or roller) passage vibration, natural vibration of the outer ring, natural vibration of the cage, vibration caused by geometrical imperfections, nonlinear vibration, abnormal vibration of grease lubricated ball bearings, vibration of defective bearings, damping and squeeze film damper are explored.
