Elastohydrostatic Lubrication of Circular Plate Thrust Bearing With Power Law Lubricants

Abstract

The problem of elastohydrostatic lubrication of circular plate thrust bearings is analyzed with non-Newtonian power law lubricants. It is seen that the elastic layer on the surface improves the bearing performance for all values of the flow behavior index n. The load is found to increase for all values of n and the rate of increase of load capacity at a given elastic parameter is higher for higher values of n. The film profile departs from its unloaded shape for an elastic layered surface and the departure is higher for small values of n.
