Abstract:

In this paper,the relative position between the slipper retainer and the ball guide in axial piston pumps is analyzed,and the force loading on them is clarified by analyzing the return force of spring.Moreover,a mathematical expression of the friction power loss casued by the moving of the slipper retainer around the ball guide is derived.The results show that the spring force,the radius of ball guide,the rotational speed of the pump,the swashplate angle and the friction coefficient between the slipper retainer and the ball guide are all important parameters that affect the friction power loss.In addition,based on the friction experiments on different matched pair materials applied to the slipper retainer and the ball guide,the wearing condition between the slipper retainer and the ball guide is comprehensively analyzed and compared,which provides a reference for the material selection in actual working conditions.

Key words: axial piston pump, slipper retainer, ball guide, relative position, friction power loss
