Power Loss of Gearbox Ball Bearing Under Axial and Radial

Mar 25, 2008· A new ball bearing behavior model which predicts and loes power losses in a high-speed gearbox angular contact ball bearing, operating under axial and radial loads, is presented. Its new features come from the consideration of both cage action and effect of lubricant film thickness in the computation of bearing kinematics at equilibrium.

Grease Lubriion Mechanisms in Rolling Bearing Systems

drag due to ball spin will probably have a greater effect (Ref. 5). Both ball spin and the narrower contact sizes make replenishment easier for ball bearings than for roller bearings. This is one of the reasons why roller bearings require grease with more bleeding than ball bearings (Ref. 11). At higher tempera-tures, oxidation and evaporation will
