Cycloid planetary gear speed reducing mechanism

Abstract

The invention relates to the technical field of speed reducers, and discloses a cycloid planetary gear speed reducing mechanism comprising a shell, a coupler and an output shaft. The coupler and the output shaft are both rotationally connected with the shell, a first-stage speed reducing assembly and a second-stage speed reducing assembly are arranged in the shell, and the coupler penetrates into the shell and then is connected with the first-stage speed reducing assembly. The output shaft penetrates into the shell and then is connected with the second-stage speed reducing assembly, and the first-stage speed reducing assembly is connected with the second-stage speed reducing assembly. A prime motor works to drive the coupler to rotate, the coupler drives the first-stage speed reducing assembly to work, and first-stage speed reduction is achieved; the first-stage speed reducing assembly and the second-stage speed reducing assembly cooperate to drive the second-stage speed reducing assembly to work, and second-stage speed reduction is achieved; and the transmission ratio of the speed reducing mechanism is effectively increased through cooperation of two-stage speed reduction effects, and the cycloid planetary gear speed reducing mechanism is simple in structure and has the advantages of being large in speed reduction ratio, small in axial size, large in output torque and low in noise.

Description

technical field [0001] The invention relates to the technical field of reducers, in particular to a cycloidal planetary gear reduction mechanism. Background technique [0002] The reducer is generally used for transmission equipment with low speed and high torque. The motor, internal combustion engine or other high-speed running power achieves the purpose of deceleration through the gear with a small number of teeth on the input shaft of the reducer meshing with the large gear on the output shaft. The working machine or actuator plays the role of matching speed and transmitting torque, and is widely used in modern machinery. [0003] At present, the Chinese invention patent with the publication number CN111536208B discloses a planetary gear reducer, including a housing, a planetary carrier, an input shaft and an output shaft, and a circular gear and three planetary gears are arranged for rotation in the housing, and the circular gear is located in the housing. center and co...

Problems solved by technology

[0004] However, the above solution only uses the circular gear to rotate the planetary gear combined on the planetary carrier, so that the planetary gear system automatically rotates along the ring gear to achieve deceleration, which is difficult to meet the user's requirements for a large transmission ratio. The effect is poor, and there are defects of small reduction ratio and small output torque
