Problems solved by technology

[0005] During this process, since the distribution support plate is coaxial with the output shaft, it only rotates around the fixed axis. When the rotor revolves one revolution, the distribution plate rotates one revolution to complete a cycle of flow distribution. As a result, the hydraulic pulsation is relatively obvious, and the output shaft It is difficult for motion output to meet the requirements of high-precision transmission stability and high volumetric efficiency

Embodiment 1

[0020] The present invention will be described in detail below in conjunction with the above-mentioned embodiments of the accompanying drawings.

[0021] The high-speed distribution cycloidal hydraulic motor of this embodiment includes a housing 1 with a liquid inlet and a return port, and one end of the housing is fixed with a back cover 10 through a partition plate 8. A cycloidal needle composed of a stator 5 and a rotor 6 is installed. The wheel set and the distribution mechanism composed of a group of distribution support plates (see 20-24 in Figure 2) and distribution plate 9 constitute the distribution mechanism, the other end of which is against the plane of the spacer ring 14 through the needle bearing 12 and one side The thrust bearing 15 is supported by the output shaft 2 protruding from the housing, the rotor 6 of the cycloidal pin wheel pair meshes with the external gear at one end of the linkage shaft 3 through the internal spline, and the external gear at the othe...

Abstract

The present invention relates to a high-speed flow distribution cycloidal hydraulic motor, belonging to the field of hydraulic transmission technology. It is characterized by that one end of said hydraulic motor shell body is equipped with a cycloidal pin gear pair formed from stator and rotor and a flow distribution mechanism composed of flow distribution support plate and port plate, and another end of said hydraulic motor shell body is equipped with an output shaft extended from the shell body interior. Besides, said invention also provides the concrete working principle of said high-speed flow distribution cycloidal hydraulic motor and its concrete operation method.

Description

technical field [0001] The invention relates to a cycloidal hydraulic motor for converting hydraulic energy to mechanical energy, in particular to a structural improvement of a hydraulic motor plane distribution hydraulic channel, which belongs to the technical field of hydraulic transmission. Background technique [0002] The cycloidal hydraulic motor is a common hydraulic actuator to realize hydraulic-mechanical energy conversion. Because the cycloid hydraulic motor has the advantages of small size, high unit power density, high efficiency, and wide speed range, it has been widely used. The basic structure of this type of device is that the shell or the back cover is made with a liquid inlet and a return port, one end is equipped with a cycloidal pinwheel pair and a flow distribution mechanism, and the other end is equipped with an output shaft, and the rotor of the cycloidal pinwheel pair passes through the inner flower The key meshes with the external gear at one end of...
