摘要：
In this paper, Thermal elastohydrodynamic lubrication (TEHL) model of a helical gear pair is proposed to study contact performance during the whole meshing period. Effects of working conditions and design parameters on lubrication performance, i.e. film thickness, pressure, temperature, friction coefficient, etc. are investigated. Influence of thermal effect and non-Newtonian effect are evaluated through a detailed study on three characteristic meshing positions. Results show that, the thermal effects and non-Newtonian fluid both have significant effects on the lubrication performance of the helical gear pair, especially in high speed, heavy load cases. The effects of normal pressure angle, helix angle and module on lubrication performance along the line of action are discussed.
