【Abstract】 It is main cause of the bearing failure that the cage motion is unsteady and damaged in high speed roller bearing. This paper systematically analyzes the forced model of the cage in the bearing. The dynamics motion equation of the cage is established. On the base of quasi-dynamics solution of the bearing in steady, the instantaneous location of mass center of the cage is found by Runge-Kutta integral method, and the effect of structure parameters of the bearing on cage motion is studied.更多还原
