Pore-pin type cycloid rotor motor

Abstract

The invention relates to a hydraulic pressure cycloid rotor type motor structure. A hole pin type cycloid rotor motor, and comprises a front end cover (6), a machine seat (9), a rear end cover (12) and a flow distribution axle (10) positioned at the axle center of the machine seat (9), the invention is characterized in that the flow distribution axle (10) is extended into the casing body (7), and an inner rotator (2) is connected coaxially and fixedly; a short amplitude outer cycloid gear is arranged in the inner rotator (2); a plurality of sleeves (3) are embedded on the inner wall of the central cavity along the parallel operating plate (5); column pins (4) with the same number of the sleeves (3) are respectively penetrated into the sleeves (3), the diameter of the column pin (4) is smaller than the sleeve (3), the column pins (4) are vertically fixed on the machine seat (9) or the end covers (6) and (7), the distribution position on the plane of each column pin is the same as the sleeve (3), and the distance between the parallel operating plate (5) and the casing body (7) is larger than or equals to the diameter difference of the sleeve (3) and the column pin (4). The invention increases the displacement of the hydraulic motor; the torque and the speed are enhanced. The structure is simplified, the manufacturing process is improved, the cost is reduced, and the mechanical efficiency and the service life of the motor are enhanced.

Description

(1) Technical field [0001] The invention relates to a hydraulic transmission motor, in particular to a structure of a cycloid rotor type motor. (2) Background technology [0002] As is known, as shown in Fig. 1 is a planetary cycloid rotor motor of the prior art, which is mainly composed of a distribution shaft, an output shaft, a housing, a spline coupling, a cycloid rotor, a stator, a front and a rear end cover. The tooth profile of the cycloid rotor is a short outer cycloid, and the stator tooth profile is an arc. Has Z 1 The cycloidal rotor with three teeth, that is, the pinion with external teeth, and has Z 2 The stator with two teeth, namely the inner ring gear meshes, forming Z 2 A closed volume. These closed volumes are connected to the inlet and outlet ports through the valve shaft. The valve shaft acts as a switching valve to control the connection or disconnection between the oil inlet and outlet ports and each closed volume. 2 Nearly half of the enclosed volume is in ...

AI Technical Summary

Problems solved by technology

The disadvantage is that because the cycloid rotor is connected with the output shaft and the distribution shaft by spline coupling, the cycloid rotor eccentricity is small, the displacement is small, the output torque is small, the speed of the cycloid rotor cannot be high, the speed range is small, and it belongs to the medium and low speed , small and medium torque range

The processing and manufacturing of the spline connection is complicated, and the stator tooth shape is an arc, and its processing and manufacturing are also complicated
