Abstract

Water-lubricated bearings are expected to be widely used because of convenience, green,safe and energy saving. The purpose of this study is to provide references for designinghydrodynamic water-lubricated step thrust bearings. The numerical analysis is undertakenunder the condition of different pad dimensions, step heights, step positions, water filmthicknesses and rotational speeds of thrust rings based on computational fluid dynamics(CFD). The results including pressure distribution, load carrying capacity, frictiontorque and friction coefficient are gained and compared for optimizing geometryparameters. A reference to determine water-lubricated step thrust bearing dimensions and aformula to check the minimum water film thickness are proposed.
