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 motor. (2) Background technology [0002] public knowledge, such as figure 1 Shown is the prior art planetary cycloid rotor motor, which is mainly composed of a flow distribution shaft, an output shaft, a housing, a spline coupling, a cycloid rotor, a stator, front and rear end covers. The tooth shape of the cycloidal rotor is a short epicycloid, and the tooth shape of the stator is an arc. with Z 1 A cycloidal rotor with three teeth, that is, a pinion with external teeth, and a Z 2 teeth of the stator, ie the inner ring gear, are meshed 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 makes the above Z...

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
