[0002] A reduction motor refers to an integration of a reducer and a motor. This integration is also commonly called a gear motor or gear motor. The reduction motor is usually integrated and assembled by a professional reducer manufacturer and supplied as a complete set with the motor. It is widely used in the reduction transmission mechanism of various general mechanical equipment such as metallurgy, mining, lifting, transportation, cement, chemical industry, textile, and pharmaceuticals.

[0003] The existing Chinese patent with announcement number CN212518594U discloses a reduction motor, which includes a reduction motor housing and a fixed frame. One end of the reduction motor housing is equipped with a transmission shaft, and a speed regulator is installed on the surface of the reduction motor housing. The fixed frame includes a bottom frame and a top frame. One end of the reduction motor housing is mounted on the upper surface of the bottom frame, and the top frame is covered and assembled on the upper surface of the reduction motor housing; the bottom frame includes a first frame plate, a second frame plate and a connecting plate for connecting the two sets of frame plates.

[0004] Although the above scheme can ensure the stability of the reduction motor housing after being connected and assembled with the fixing frame, the reduction motor has only one output shaft and cannot meet the requirements of multiple working directions or tasks at the same time, resulting in insufficient practicality. At the same time, heat will accumulate when the reduction motor is working, and there is a lack of effective heat dissipation, which affects normal use. Therefore, it does not meet the existing needs. In this regard, we propose a multi-output shaft reduction motor. Utility Model Content

[0037] Working principle: When in use, start the reduction motor 1, and the main shaft 7 can be rotated under the transmission of the coupling.
