Abstract :
A load distribution model in consideration of ball off size for deep groove ball bearing is put forward. For single off-sized ball, effects of magnitude of off size and external load are analyzed. For multiple off-sized balls, both effects of number and arrangement of off-sized balls on bearing load distribution are studied. For single off-sized ball, the results indicate that ball contact load fluctuation is linearly dependent on the value of off size, and has a non-linear relationship with external load. In addition, the variation of ball contact load is a function of its circumferential position. For multiple off-sized balls, both relative off size value and relative position of off-sized balls have significant effects on load distribution.
