Description

Hydraulic motor convenient to dismantle

Technical Field

The utility model relates to the technical field of hydraulic motors, in particular to a hydraulic motor convenient to detach.

Background

According to the working principle of the radial plunger type hydraulic motor, when pressure oil enters the bottom of a plunger in a cylinder body through a window of a fixed oil distribution shaft, the plunger stretches out to tightly prop against the inner wall of the stator, and an eccentric distance exists between the stator and the cylinder body. At the contact of the plunger and the stator, the reaction force of the stator to the plunger is as follows. The force may be split into two components. When the oil pressure acting on the bottom of the plunger is p, the diameter of the plunger is d, and the included angle between the force and the force is X, the force generates a torque on the cylinder body, so that the cylinder body rotates. The cylinder body outputs torque and rotation speed outwards through a transmission shaft connected with the end face. In the case where one plunger analyzed above generates torque, since several plungers act on the pressure oil area, the generated torque on these plungers rotates the cylinder and outputs the torque. Radial plunger hydraulic motors are commonly used in low speed, high torque situations.

The radial plunger type hydraulic motor adopts screw connection on the installation, when the motor breaks down or regularly overhauls, need dismantle the inspection to the motor, but current radial plunger type hydraulic motor dismantles the in-process and need use specialized tool, dismantles comparatively waste time and energy, is unfavorable for periodic maintenance.
