Abstract

This study presents a thermobydrodynamic solution for a finite width journal /wring operating with non-Newtonian lubricants, obeying the power law model. The steady-state characteristics are obtained by solving simultaneously the generalized Reynolds equation, the energy equation and the heat conduction equations m the bush and the shaft, satisfying the boundary conditions. Heat transfer is assumed to be three-dimensional in the fluid and the bush and two-dimensional in the shaft. The generalized Reynolds equation and the heat conduction equations are solved by the finite difference technique with a successive over-relaxation scheme, while the energy equation is solved by an implicit Richtmyer technique. The load carrying capacity of the bearing is compared with an isothermal analysis assuming die bush and the shaft to be perfect conductors.
