The Influence of Race failure on Ball Motion in a Radial Ball Bearing Under Radial Loading : Vibration, Control Engineering, Engineering for Industry

Abstract

Many investigations into the problems of ball motion in ball bearings have been reported. However, studies of the influence of race failure on ball motion are few. Recently, utilizing the Hall effect, a new method for measuring three-dimensional ball motion was developed so that it is now possible to analyze the angular velocity components of ball motion from experimental data. The authors carried out a series of experiments on ball motion using damaged bearings. In this paper, the experimental results obtained under a shaft speed of N_i=12 rpm, 1000 rpm and a radial load of Pr=490 N are reported. The effect of shaft speed and the influence of a damaged race on ball motion are discussed, based on the analysis of the experimental data.
