A method for forming an exact self-similar solution to the problem of hydrodynamic calculation of a radial plain bearing that operates in a steady-state friction mode in the presence of a lubricant has been constructed. Based on the equation of motion for a viscous incompressible electrically conducting liquid in the case of a “thin layer,” the continuity equation, and expressions for the dissipation rate of mechanical energy, an analytical relationship for the molten surface profile of fusible coating on a bearing bush taking into account the viscosity and electrical conductivity of a liquid lubricant depending on pressure is obtained. The effect of the parameters characterizing the dependence of viscosity and electrical conductivity on pressure and the effect of a parameter caused by melting the fusible coating surface of the bearing bush exerted on the bearing capacity and friction force are demonstrated.
