Analytical and fem simulation studies on friction resistances in angular ball bearing

The paper presents analytical and FEM results of friction resistances in angular ball bearing. Theoretical considerations concerning the motion in angular-ball bearing were presented in the article. It has been hypothesized that since the phenomenon of the bearing ball spinning, sliding and rolling can be observed in the angular-ball bearing, the resulting motion resistance can significantly affect the overall motion resistance due to the friction between the balls and bearing raceways. A simple mathematical relationship has been developed for the calculation of motion resistance due to the spinning, sliding and rolling phenomenon. Experimental studies of motion resistance in the ball bearing were conducted in order to verify the analytical model and obtained results confirmed adequacy of the developed models.
