Optimal design of a frictional pair of a hub–plunger

Resumo

Based on the model of a rough friction surface, the theoretical analysis of the displacement function for the external contour points of the hub of a frictional pair, providing the absence of the initial wear and tear, which takes place towards the end of the bedding period, is carried out. The obtained displacement function for the external contour points of the hub provides increased wear resistance of the frictional pair.
