چکیده انگلیسی
Non-Newtonian thermal elastohydrodynamic lubrication (EHL) theory in point contact which deals with the lubrication for a crowned herringbone gear drive is developed, combined with the verified numerical procedure. Effects of the major geometry and working parameters on the lubrication performance (the pressure, film thickness, temperature rise and shear stress), are investigated. The results show that the enlargement of normal module, normal pressure angle, helix angel, and transmission ratio is beneficial for pitting resistance, and that the excessive crowned can debase the contact fatigue strength. It is indicated that severe thermal deformation and scuffing are prone to generation under large load and speed.
