Abstract

The invention discloses a small-area contact chuck ball hinge friction pair structure, which comprises a chuck and a ball hinge, wherein a mounting hole is formed in the chuck; an annular contact zone arranged along the inner wall of the mounting hole is arranged on the inner wall of the mounting hole; the width of the annular contact zone is smaller than that of the inner wall of the mounting hole; the annular contact zone is raised from the inner wall of the mounting hole, and contacts with the surface of the ball hinge. According to the small-area contact chuck ball hinge friction pair structure, a contact friction part is changed into an annular zone shape on the basis of an original ball hinge chuck friction pair design, so that friction energy loss is reduced, reliability and stability are improved, machining difficulty is reduced, and the efficiency of a grinding procedure is improved.

Description

technical field [0001] The invention relates to the technical field of hydraulic equipment components, in particular to a small-area contact friction pair structure of a chuck ball hinge. Background technique [0002] Axial piston motors and piston pumps are widely used in the fields of industrial hydraulics and travel hydraulics. As an important component in the hydraulic system, the energy transfer and energy loss of the axial piston motor and piston pump are the focus of research. Chuck spherical hinge friction pair is one of the important friction pairs in axial motors and plunger pumps. How to reduce its frictional energy loss while ensuring its reliability and stability makes its research significant. [0003] At present, domestic manufacturers of axial piston motors and plunger pumps mostly use full-contact or large-area contact friction pairs in the research of chuck ball-joint friction pairs. This method has been greatly guaranteed in terms of reliability, but due...
