[0002] The worm gear reducer is a power transmission mechanism that uses the worm gear speed converter to reduce the number of revolutions of the motor to the desired number of revolutions and obtain a larger torque. In the mechanism used to transmit power and motion, the reducer has a wide range of applications. At this time, the worm gear and the worm need to contact each other, and high-speed rotation will generate heat, causing damage to the device;

[0003] According to the Chinese patent announcement number: CN220396427U, a worm gear reducer with heat dissipation function is disclosed, wherein the shaft end of the worm can quickly circulate the air around it through the action of the fan, so that the shaft end of the worm can be effectively cooled. Since the fan is clamped by the first spring and the arc block, the fan can be quickly disassembled and installed, which can save the time of installing the fan.

[0004] However, in this technical solution, the fin heat dissipation mechanism and the fan can only dissipate heat and cool one side of the worm gear reducer, which makes it difficult to quickly cool the worm gear reducer, thereby affecting the normal use of the worm gear reducer.
