V-shaped sliding bearings using micropolar lubricants caused by a melt accounting for the dependence of lubricant viscosity and porous lauer permeability on pressure

Abstract

The paper presents a method for formation of an exact self-similar solution of the hydrodynamic calculation of a wedge-shaped slip bearing (slide, guide) using a micropolar liquid lubricant caused by a melt of the guide taking into account the dependence of lubricant viscosity and porous lauer permeability on pressure. Based on the system of motion of a viscous incompressible fluid of a micropolar lubricant for the “thin layer” taking into account the dependence of viscosity characteristics of the micropolar lubricant and permeability of the porous layer on pressure, continuity equations and equations for the dissipation rate of mechanical energy, an analytical dependence for the molten surface profile was obtained. In addition, performance characteristics of the friction pair were determined. The influence of parameters caused by the melt of the guide, structural-viscous parameters of the micropolar liquid lubricant and permeability of the porous layer on the bearing capacity and friction force was estimated.
