[0021] A heat dissipation port 3 is provided on one side of the lower housing 1, and an input shaft hole 4 and an output shaft hole 5 are provided at the corresponding two ends of the lower housing 1. The input shaft hole 4 and the output shaft hole 5 are holes on the reducer housing for installing the input shaft and the output shaft. The input shaft hole 4 and the output shaft hole 5 are cylindrically designed and match the diameters of the input shaft and the output shaft. An oil drain hole 6 is provided at the bottom of the other side of the lower housing 1. The oil drain hole 6 is a hole for discharging lubricating oil and is equipped with an oil drain valve;

A plurality of plugging interfaces are provided at the bottom of the second mounting seat 9, and the positions of the plurality of plugging interfaces match the positions of the plurality of clamping blocks 7. The second mounting seat 9 is plugged into the first mounting seat 2 through the clamping block 7. The tight fit between the plugging interface and the clamping block 7 can effectively prevent the mounting seat from loosening or shaking during operation, thereby ensuring stability.

[0023] An upper shell 8 is installed on the top of the second mounting seat 9, and a fin 10 is installed on one side of the bottom of the upper shell 8. The heat dissipation port 3 is located below the first mounting seat 2. A slide groove matching the size of the heat dissipation port 3 is opened on the first mounting seat 2. The fin 10 is vertically arranged at the bottom of the upper shell 8. The fin 10 passes through the slide groove and is slidably connected to the heat dissipation port 3. The fin 10 is made of metal, which can increase the heat transfer area, speed up the heat transfer speed, and help the reducer to dissipate heat inside.
