Abstract

Swiveling shaft friction pair is one of the swiveling cylinder-type high water-based hydraulic motor’s main friction pairs. In the actual condition of high pressure, low speed, and high torque requirements, the swiveling shaft will be affected by the large radial force. Under the action of this force, complete lubricating water film cannot be formed in the swiveling shaft friction pair’s annular gap, which aggravates the wear and tear of swiveling shaft friction pair. In this paper, the load-carrying characteristics of the swiveling shaft friction pair’s lubrication water film are studied by CFD simulation. Based on the theory of hydrostatic bearing, the structure of the swiveling shaft friction pair is optimized, by which the swiveling shaft friction pair can be self-balanced and guarantee the existence of lubrication water film under most working conditions, which can reduce the friction and wear of the swiveling shaft friction pair.
