Abstract
This paper presents a study of lubrication of Kimberly type thrust bearing with non-Newtonian lubricant under isothermal time independent with non-Newtonian lubricant based on Carreau viscosity model. Numerical scheme based on the finite difference method and multi-grid multilevel technique with Newton-Raphson method were implemented to obtain the film pressure profile, film thickness profile, friction coefficient and angle-pitch of thrust bearing with various applied loads, the amplitude of surface roughness and shaft speeds. The simulation results show the minimum film thickness decreases but film pressure, friction coefficient and angle-pitch of thrust bearing increase when the amplitude of surface roughness increases. With the increasing of applied loads, the film pressure increases but the minimum film thickness, friction coefficient and angle-pitch of thrust bearing decrease. The minimum film thickness, friction coefficient and angle-pitch of thrust bearing increase but the film pressure decreases when shaft speed increases.
