[0002] Gear reducers are generally used for low-speed and high-torque transmission equipment. Ordinary reducers for electric motors will also have several pairs of gears with the same principle to achieve the ideal deceleration effect. The ratio of the number of teeth of large and small gears is the transmission ratio. With the continuous development of the reducer industry, more and more companies have used reducers. Gear reducers use various levels of gear transmission to achieve the purpose of speed reduction. The reducer is composed of various levels of gear pairs. For example, using a small gear to drive a large gear can achieve a certain deceleration purpose. By adopting a multi-stage structure, the speed can be greatly reduced. During use, when the gear reducer runs at high speed for a long time, a large amount of heat is often generated due to internal gear friction, resulting in excessive temperature of the reducer, thereby affecting its working efficiency and service life.
