Friction and Wear Analysis of Grease-Lubricated Ball Bearing Based on EHL Numerical Calculation

摘要：

Through the numerical calculation on elastohydrodynamic lubrication of grease lubricated ball bearing its obtained that: for the outer ring fixed, inner ring rotating with the shaft ball bearing type, as a result of the relative speed of steel ball-inner ring friction pairs is faster than the steel ballouter ring, the film pressure peak and average film pressure on steel ball-inner ring friction pairs is greater than those of steel ball-outer ring, therefore, inner ring surface compared with outer ring is more likely to appearance wear and fatigue failure; In the process of steel ball rotation, theres a rotation torque which caused by the asymmetry distribution of film pressure generated, and this rotation torque accelerates the rotation speed of steel ball.
