Minimization of abrasive wear for the internal surface of the hub of a friction pair

Abstract

Based on the minimax criterion and model of the friction rough surface, a theoretical definition has been developed for the displacement function of hub external contour that provides the minimization of abrasive wear in the hub–plunger friction pair. A closed system of algebraic equations has been developed that allows one to minimize the abrasive wear in the friction pair that depends on the geometric and mechanical characteristics of its elements.
