Abstract

This paper represents a numerical iterative scheme for calculation of finite 360° journal bearings with longitudinal and transversal rough surfaces. A modified Christensen's Reynolds type equation is solved numerically under isothermal boundary condition. The Reynold's boundary condition assuming that the pressure and its derivative vanish near the point of location of the minimum film thickness is used in an iterative scheme to find out this location. Results of the analysis show the great influence of surface roughness on the bearing behaviour, especially when the bearing operates at its hydrodynamic limit.
