Characteristics of a Slipper Bearing for Swash Plate Type Axial Piston Pumps and Motors : 1st Report, Theoretical Analysis

Abstract

A slipper bearing is one of the factors which affect significantly the performance of swash plate type axial piston machines. In this paper, considering all the oil-film parameters, that is, tilting angle, maximum tilting angle azimuth and mean clearance, a theoretical analysis on the characteristics of the slipper bearing is made from the standpoint of fluid film lubrication. As numerical examples, changes in the oil-film parameters due to a rectangular change of a supply pressure are shown. And also, the limit of fluid film lubrication is given in relation to the supply pressure and the rotational speed.
