Wear Research and Improvement Design of Slipper Pair in Axial Piston Hydraulic Motor Lubricated with High Water Based Fluid

摘要

The flow field of lubrication film under the bottom of the slipper is analyzed particularly. The velocity in different points of the lubrication film on the bottom of the slipper is solved based on the premise that the rotation and self-rotation of the slipper has been taken into account of. This paper puts forward that regular concaves converging along the radial direction be set up in the cyclic zone of slipper's bottom surface to enhance the lubrication effect and improve the overwear situation in the peripheral parts of the slipper.
