【 摘 要 】

The method for the formation of an exact self-similar solution of the hydrodynamic calculation of wedge-shaped support (sliding bearing, guide bearing) with a porous coating of a slide, which operates in the presence of a lubricant and the melt of a guide coated with a free-melting metal cover. The analytical dependence for the molten guide surface is obtained on the basis of the equation of motion of a viscous incompressible fluid for a "thin layer," the equation of continuity and the equation for the dissipation rate of mechanical power. In addition, the main performance characteristics of the investigated friction pair are determined. The assessment of the effect of the parameter caused by the guide melt and the parameter characterizing a porous layer on the slide surface on the bearing capacity and friction power is made.
