[0002] A reduction motor is an integrated unit consisting of a speed reducer and a motor. This unit is also commonly referred to as a gear motor or gear motor. A speed reducer is a self-contained component consisting of a gear transmission, worm drive, or gear-worm drive enclosed in a rigid housing. It is commonly used as a reduction transmission device between the prime mover and the working machine. It matches speed and transmits torque between the prime mover and the working machine or actuator, and is widely used in modern machinery.

[0003] When the reduction motor is in use, there are many components inside the reduction motor. When the various components work together, a large amount of heat is generated, and the internal heat of the reduction motor needs to be dissipated. At the same time, when the reduction motor is assembled, the sealing cover of the reduction motor is usually installed with the shell body by bolts. However, this installation method is more cumbersome during later maintenance and disassembly, which will correspondingly increase working time, thereby reducing work efficiency and making it inconvenient to install and disassemble the sealing cover of the reduction motor.

Furthermore, a cooling fan is provided at one end of the first rotating shaft and the second rotating shaft. When in use, the fan is driven to rotate by a right-angle converter to cool the cylinder and the internal motor body, thereby better dissipating heat while saving energy. Moreover, a clamping assembly is provided on both the first sealing cover and the second sealing cover. By pulling the pull rod, the first slider is driven to slide, and the first slider is moved away from the cylinder, so that the first sealing cover and the second sealing cover can be removed from or installed on the cylinder.
