Abstract

The invention relates to an oblique-shaft type axial plunger pump/motor with a novel-structured plunger. The oblique-shaft type axial plunger pump/motor with the novel-structured plunger comprises a housing, a bearing cover, a spindle, the plunger, a cylinder body, a valve plate and a rear cover. The plunger is inserted inside the cylinder body hole of the cylinder body and hinged to a ball socket in the spindle through a ball joint at one end; the ball joint of the plunger is provided with a cylindrical step structure. By means of the improvement of the ball joint structure of the plunger, the oblique-shaft type axial plunger pump/motor with the novel-structured plunger can reduce the vibration during operation, accordingly, reduce the noise, improve the efficiency and further prolong the service life.

Description

technical field [0001] The present invention relates to the technical field of hydraulic and mechanical control, in particular to an inclined-axis axial piston pump / motor, in particular to an inclined-axis axial piston pump with a new type of plunger with cylindrical steps / motor. Background technique [0002] The inclined shaft axial piston pump or motor is a kind of axial piston pump or motor, the axis of the main shaft and the rotation axis of the cylinder are not on the same straight line, but form an included angle. Functionally, it can be used as a pump as well as a motor. Inclined axial piston pumps are widely used in hydraulic systems because of their small size, low friction loss, strong self-priming ability, and high starting efficiency. [0003] Such as figure 1 Shown is a schematic structural diagram of an existing inclined-axis axial piston pump / motor. The existing oblique-shaft axial piston pump / motor is mainly composed of a bearing cover 100, a main shaft ...
