Some Aspects of Bearing Noise Generation

Abstract

Problem of ball bearing and roller bearing noise generation is important in present technology level, and its solution stands in front for a new machine designer. New materials of bearings create new problems of bearing noise generation, so research of noise and vibration generation mechanism in necessary. Problem of lubrication gives significant influence to vibration and noise generation in bearings, so in common task of bearing work vibration is quite complex and requires experimental verification of theoretical ideas. This paper is intended to cover noise generation mechanism of ceramic bearings in comparison to steel ones and evaluate influence of bearing lubricant with different properties. There are presented design of experimental workbenches, experimental research procedure and results from research. Experimental results material is presented graphically and numerically. Finally, conclusion on problem and results of experimental research are made.
