Problems solved by technology

However, another type of internal mechanical loss in the rotation variable volume movement has become a prominent problem. In some cases, the volume loss may also be too large
[0005] In addition to the above efficiency bottlenecks, another problem with existing fluid machinery is the singleness of goals and products
Unity is not universal, a product can only be used for one purpose, and can only be used under one set condition

Embodiment Construction

[0032] A preferred embodiment of the present invention is shown in FIGS. 1 to 13 . It can be seen from the figure that the main components of the hydraulic motor 200 include a main shell 201, an end cover 202, a main shaft 203, a kneading wheel 204, an output shaft 205, a protective shell 206, and an isolation limiter 209. Wherein, the main housing 201 and the left and right end caps 202 form a rotating body, and the output shaft 205 is connected to the right end cap and can rotate synchronously with the rotating body.

[0033] As can be seen from Fig. 1 and Fig. 3, two kneading chambers 221 for installing kneading wheels are symmetrically arranged in the rotating body. As shown in Figure 2, the diameter of the kneading chamber is slightly larger than that of the kneading wheel, so that when the kneading wheel is installed in the kneading chamber, there is an appropriate clearance for movement. It can be seen from Fig. 1 and Fig. 3 that on both sides of the kneading chamber 2...

Abstract

It relates to a hydraulic motor that comprises the main shell, end cap formed rotation part, output shaft, main shaft, connected with the rotation part, rub wheel, protective shell, isolating stop part. When the high pressure liquid flows from the liquid inlet hole, it can go through the liquid hole, liquid ejection to flow to the slot on the rub wheel, through through hole of the rub wheel to flow to the gap between the rub wheel ring surface and rub cavity inner wall at the first side of the isolating stop part, with the high pressure liquid shocking the inner wall of the rub cavity to drive the synchronic movement of the rotation part, rub wheel and the output shaft, with the main shaft kept fixed, liquid after released pressure going into liquid return cavity through the liquid guide slot on the rub wheel of the second side of the isolator stop slot, and through the liquid return hole on the main shaft to flow from the liquid output hole. It can change energy efficiency, being able to output higher rotation speed under relatively low pressure.

Description

technical field [0001] The present invention relates to a hydraulic motor, and more particularly, to a hydraulic motor with high efficiency and outputting a relatively high rotational speed driven by a relatively low-pressure liquid. Background technique [0002] In order to achieve energy transmission, it is usually necessary to use high-pressure liquid to drive the object to rotate, which results in a hydraulic motor. The medium hydraulic motors in the prior art mainly include vane motors and plunger motors. Although they have a rotating structure, the movement mode of the variable capacity mechanism is still a linear translation, or it should be called a linear translation superimposed on the rotation. The principle of variable capacity of the two is different. The vane motor uses the radially stretchable vanes in the rotor to divide the relatively eccentric cavity to cause periodic changes in the volume of the fan-shaped area between the vanes. The plunger motor uses ...
