HYDRODYNAMIC THEORY OF THE LUBRICATION OF POROUS BEARINGS,

Abstract

A method is proposed for the analysis of porous metal-ceramic bearings of finite length using an approximate boundary condition to relate the velocity and pressure differential on the lubricant layer-bearing interface in the form of Darcy's law. Determination of the pressure distribution function in the lubricant layer is resolved to the joint solution of a Reynolds equation containing a term to take into account the porosity of the bearing and a Laplace equation describing the pressure distribution within the body of the bearing itself. Numerical values for the nondimensional bearing capacity are assigned.
