Description

[0002] A reducer is an independent component consisting of a gear transmission, a worm transmission, or a gear-worm transmission enclosed in a rigid housing, and is often used as a reduction transmission device between a prime mover and a working machine. At present, reducers include gear reducers, which usually use the lubricating oil of the housing to lubricate the gears and conduct heat.

[0003] The lubrication mechanism of the existing gear reducer still has the following problems when in use: most of them are oil circulation systems and are arranged in the housing of the reducer. When lubricating and conducting heat for the gears, the lubricating oil relies on the reducer housing for passive heat dissipation. After the reducer has worked for a long time, the oil temperature of the lubricating oil is too high to be easily dissipated passively, and thus the lubrication mechanism cannot quickly conduct and dissipate the heat of the gears in the reducer.
