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

[0003] During operation, lubricating oil is added to the inside of the reducer gearbox to lubricate the gears and reduce the wear between the gears. However, the gears and the bearings inside the gearbox will also wear when rotating for a long time. The impurities produced by the wear will be mixed in the inside of the lubricating oil, which will reduce the lubricating effect of the lubricating oil, thereby accelerating the wear of the gears and bearings and reducing the service life of the gears and bearings. When the gears and bearings are severely worn, the friction will increase, thereby aggravating the heat and heating of the friction of the gears and bearings, causing the entire gearbox to heat up.
