Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic motors, in particular to a radial piston hydraulic motor. Background Art

[0002] The hydraulic motor is an actuator of the hydraulic system. It converts the liquid pressure energy provided by the hydraulic pump into the mechanical energy (torque and speed) of its output shaft. Hydraulic motors can be divided into gear type, vane type, plunger type and other types according to their structural type. The plunger hydraulic motor inputs high-pressure oil, which drives the plunger to rotate around the main shaft and make a linear motion from the high point to the low point of the swash plate. The plunger on the other side pushes the oil out on the swash plate with a certain angle, forming a rotational motion, and this reciprocating motion causes the motor to output a rotating speed.

[0003] When the radial piston hydraulic motor is working, it needs to be fixed at the installation location. However, since the housing of the radial piston hydraulic motor is cast through a mold of a unique shape, the shape of the radial piston hydraulic motor housing is not easy to change after molding. In addition, since the installation locations of the radial piston hydraulic motor are not all the same, there are certain limitations in the installation process of the hydraulic motor. Therefore, a radial piston hydraulic motor is proposed to solve the above problems. Utility Model Content
