Water Lubricated Bearing Lubrication Model Based on Multilayer Gridding

Abstract:

The principle of the multilayer gridding algorithm, as well as its applications to the numerical calculation of water lubricated plastic alloy bearing elastohydrodynamic lubrication (EHL), was described. The computation of water lubricated plastic alloy bearing EHL was carried out by the numerical model based on the linear contact theory. A cuneiform water film on the frictional surface between bearing and spindle is formed because the plastic alloy has a high elasticity and low elastic modulus, which lead the water lubricated bearing easy to be distorted.
