Description

Technical Field

[0002] A speed reducer is an independent component composed of gear transmission, worm transmission, and gear-worm transmission enclosed in a rigid housing, and is commonly used as a speed reduction transmission device between a prime mover and a working machine. It plays a role in matching the rotational speed and transmitting torque between the prime mover and the working machine or actuator, and is widely used in modern machinery.

[0003] At present, some speed reducers on the market do not have a cooling fan, so the temperature rises during operation and effective heat dissipation cannot be achieved; although some motors are equipped with a cooling fan, the fan is facing one side of the housing of the motor in the speed reducer. Therefore, when the fan rotates, the generated air flow can only pass through one side of the housing of the motor in the speed reducer. Therefore, only one side of the housing of the motor in the speed reducer is cooled, rather than the entire housing of the motor in the speed reducer, resulting in poor heat dissipation effect.
