Abstract

The paper is devoted to the study of a new mathematical method for simulating the movement of a truly viscous lubricant in the working clearance of a modified design of a radial sliding bearing.

To assess the wear resistance of the specified structure, the developed new mathematical method takes into account a polymer coating with an axial groove, a non-standard support profile and the compressibility of the lubricant.

The new mathematical models obtained allow us to estimate the duration of the hydrodynamic lubrication regime, to make a calculated assessment of the effect of a polymer coating with an axial groove, taking into account the compressibility of the lubricant and a non-standard support profile on the main performance characteristics of sliding bearings: hydrodynamic pressure, load capacity and friction force.
