Example Embodiment

[0029] Example 1:

[0030] Such as image 3 , Figure 4 Shown, a double cycloid hydraulic motor. The motor is mainly composed of the output shaft 1, the distribution shaft 10, the front end cover 2, the base 3, the spline coupling 4, the housing 5, the outer rotor 6, the pin teeth 7, the inner rotor 8, the rear end cover 9, etc. Component composition. The inner rotor 8 is a short-width outer cycloid or a disc; the needle teeth 7 are eccentric needle teeth, which are positioned by holes and rotate eccentrically. The positioning hole centers of the needle teeth 7 are distributed on a cylinder with the rotation center of the outer rotor 6 as the central axis. The outer rotor 6 is a short-amplitude hypocycloid ring gear, and the inner rotor 8 is eccentrically arranged relative to the outer rotor 6. When the inner rotor is a disc, the eccentricity of the needle teeth is equal to the eccentricity of the inner rotor; when the inner rotor is a short-width epicycloid gear, the eccentricity ...

[0031] Example 2:

[0032] Such as Figure 5 , Figure 6 As shown, a double cycloid hydraulic motor is mainly composed of an output shaft 1, a front end cover 2, a valve 10, a front frame 3, a spline coupling 4, a casing 5, and a hypocycloid outer rotor 6. , Needle teeth 7, outer cycloid inner rotor 8, rear base 12, rear end cover 9 and other parts. The outer rotor 6 is a short-width inner cycloid, the inner rotor 8 is a short-width outer cycloid or a disc, and the needle teeth 7 are eccentric needle teeth. The output shaft 1 is fixedly connected with the hypocycloid outer rotor 6; the pin teeth are positioned by holes and rotate eccentrically. The positioning hole centers of the pin teeth 7 are distributed on the circumference with the rotation center of the outer rotor as the center of the circle; the inner rotor 8 is relative to the outer rotor 6 Eccentric setting. When the inner rotor is a disc, the eccentricity of the pin teeth is equal to the eccentricity of the inner rotor; ...

Abstract

A double-cycloid hydraulic motor comprises a output shaft, front and back end caps, a distributing valve, a motor base, internal and external rotors and several pin teeth. The output shaft is connected with the internal rotor each other. The pin teeth disposed between the external and internal rotors are engaged with the external and internal rotors at the same time. Between the internal and external rotors and the pin teeth are formed several independent enclosed tooth cavities, which are in communication with the distributing valve separately and then in communication with the fuel inlet and outlet through the distributing valve.

Description

technical field [0001] The invention relates to a hydraulic transmission device, in particular to a hydraulic motor. technical background [0002] figure 1 Shown is an existing planetary rotor type cycloidal motor, which is mainly composed of an output shaft, a flow distribution shaft, a housing, a spline coupling, a cycloidal rotor, a stator, a front end cover and a rear end cover. The distribution shaft is the output shaft, the tooth shape of the cycloidal rotor is a short epicycloid, and the tooth shape of the stator is an arc. with Z 1 The cycloidal rotor with three teeth is the external tooth pinion, and has Z 2 The stator with four teeth, that is, the inner ring gear, meshes to form a Z 2 a closed volume. These closed volumes are connected to the inlet and outlet ports through the distribution shaft, and the distribution shaft acts as a switching valve, controlling the connection or disconnection between the inlet and outlet ports and each closed volume, which mak...
