ANALYSIS OF THE LOADING AND FRICTION CONDITIONS OF THE PLUNGER-BUSHING TRIBO-CONJUGATION IN A HYDRAULIC MOTOR (HYDRAULIC PUMP)

Abstract

Processes in elements of axial-piston hydraulic machines that are widely used in hydraulic systems of aviation and space technology are considered. The analysis of the main force factors that affect the plunger during operation as part of the hydraulic motor is carried out. The effect of the hydrodynamic forces acting between the surfaces of the plunger and the sleeve is analyzed, which significantly changes the pattern of the load distribution between the contact zones. The size of the actual zones of direct contact of the plunger in the sleeve is estimated, which characterizes the presence of both semi-liquid friction regime and zones of fluid (hydrodynamic) friction.
