Abstract

Abstract

This paper combines the thermal elastic hydrodynamic lubrication(TEHL) analysis with the loaded tooth contact analysis(LTCA) to predict the slide friction efficiency of the spur gear. LTCA is used to calculate the normal load and kinematics of the discrete contact points for the TEHL. The multi-level method, multi-level multi-integration (MIMI) approach and the sequential column sweeping for solving the pressure, elastic deformation and the temperature of the lubricated regions are used alternatively. The results show that when the change of tooth load is small, the effect of the load to the friction coefficient can be ignored; but the larger increase of the load will lead to reduced friction coefficient.
