Abstract
A numerical dynamic analysis of ball bearing is presented. The normal contact forces between balls and races are calculated, respectively, based on Hertz contact theory and elastohydrodynamic lubrication theory, and the results are compared to study the effect of elastohydrodynamic lubrication on the simulation. The dynamic model of ball bearing is developed with the assumptions that outer race is fixed in space and other elements have six degrees of freedoms. The lubricant film between balls and races is equivalent as the spring–damper system when elastohydrodynamic lubrication effect is considered. The equations of motion are solved by the fourth-order Runge-Kutta integration method with variable steps. The results indicate that the effect of elastohydrodynamic lubrication has great influence on the dynamic analysis result when the load is slight. As the load increases, the effect of elastohydrodynamic lubrication becomes small.
