Abstract

This paper presents the performance characteristics of time independent isothermal hydrodynamic lubrication for Taper-Land type thrust bearing with non-Newtonian lubricant base on Carreau viscosity model. The numerical simulations employed a finite difference method Newton-Raphson method and multigrid method to solve the modified Reynolds equation under steady state conditions. The results are implemented to investigate the film thickness and film pressure profiles between bearing surface and friction coefficient with various applied loads, shaft speeds, and slot of taper region of thrust bearing. The simulation results show the minimum film thickness and friction coefficient decrease but maximum film pressure increase when applied load increases. The minimum film thickness and friction coefficient increase but maximum film pressure decreases when shaft speed increases. For increasing of slot of taper region of thrust bearing, maximum film pressure increases but friction coefficient decreases.
