Abstract:
A numerical simulation of finite line contact elastohydrodynamic lubrication(EHL)for spur gear is introduced to deal with the lubrication problem of spur gear of offset press ink vibrator that includes both rotational and axial velocities. First, with the help of the EHL theory, the governing equations containing the rotational and axial velocities are proposed after the geometric analysis, which include the Reynolds equation, the geometric equation of oil film, the viscosity equation, the density function, and the equilibrium equation of load. Secondly, the governing equations are nondimensionalized to improve the numerical efficiency and calculation convergence. Finally, the finite difference method is used to discretize the strong nonlinear equations and the multigrid method is applied to solve the discrete equations. The numerical results show that the model can accurately predict the oil film pressure and thickness under different conditions of spur gear and obtain the corresponding friction factor. It is an effective tool for studying the two-dimensional spur gear friction.
