Abstract： In this paper， the problem of linear contact elastohydrodynamic lubrication of gears is solved based on multigrid method， and the influence of different parameters on the calculation results is discussed. It is found that oil film pressure and oil film thickness are sensitive to the change of load elastic modulus. On the basis of solving the problem of isothermal elastohydrodynamic lubrication of gears， the effects of thermal effect， time-varying effect and wall roughness on lubrication are considered.

Keywords： elastohydrodynamic lubrication; spur gear; thermal effect; roughness; time-varying effect
