[0002] When the reduction motor is working, it will generate a lot of heat. In order to ensure the normal operation of the motor and extend the service life of the motor, the motor needs to be cooled.

The mounting mechanisms comprise a limit block, two fixing plates, two elastic cords, two fixing rings, two fixing brackets, and two connecting plates, the limit block being positioned on the mounting frame, and the elastic cord being fixedly connected between the connecting plates and the fixing rings. The utility model utilizes the coordination of the mounting frame, the heat dissipation fan, the limit block, the fixing block, the fixing plates, the elastic cord, the fixing ring, the fixing bracket, the threaded column, and the threaded barrel, so that the limit block limits the position of the fixing block, thereby facilitating installation and removal of the heat dissipation fan, facilitating maintenance of the heat dissipation fan, reducing work time, and improving work efficiency.

[0004] The above-mentioned reduction motor with good heat dissipation effect uses a cooling fan to blow air to the motor body to dissipate heat. However, the cooling fan needs to be connected to an external power supply for power supply when blowing air, thereby increasing energy loss. At the same time, it cannot dissipate heat over a large area of ​​the motor body, and there are still deficiencies in heat dissipation.

[0005] In view of this, this application is filed. Utility Model Content

[0006] In order to solve the problem that the cooling fan of the reduction motor with good heat dissipation effect needs to be connected to an external power supply for power supply when blowing air and is still insufficient in heat dissipation, a reduction motor is proposed.

[0008] By adopting the above technical solution, the motor shaft on the motor drives the fan blades to rotate during operation, thereby blowing air to dissipate heat from the motor. There is no need to connect an external power supply, which effectively utilizes the power of the motor during operation, thereby greatly saving energy loss. At the same time, the multiple evenly arranged air outlets opened on the left end face of the casing can evenly disperse the cold air blown out by the fan blades to various parts of the outer surface of the motor, thereby achieving large-area heat dissipation of the motor and having a good heat dissipation effect.

[0009] A raised boss is fixed on the right end of the motor, and a plurality of compression screws arranged evenly in a circumference are threadedly installed on the right end edge of the boss, and the compression screws are pressed against the edge of the sleeve.

[0022] 1. The motor shaft on the motor drives the fan blades to rotate during operation to blow air and dissipate heat from the motor. There is no need to connect an external power supply. This effectively utilizes the power of the motor at work, thereby greatly saving energy loss.

[0023] 2.
