Speed reducer having air cooling and vibration reducing gear and gap eliminating structure

Abstract

The invention discloses a speed reducer having an air cooling and vibration reducing gear and a gap eliminating structure. The speed reducer comprises a speed reducer shell, a gear transmission mechanism and an air cooling device, wherein the air cooling device comprises a fan, an air filter and an oil-air separator. The speed reducer further comprises a first butterfly spring for applying axial thrust to a first bevel gear, and a second butterfly spring for applying axial thrust to a fourth bevel gear; and the second bevel gear and the fourth bevel gear of the speed reducer both comprise inner ring bodies, outer ring bodies and vibration reducing blocks. The speed reducer cools a gear and lubricating oil through the air cooling device, and can prevent the problems of temperature rise and performance reduction of the lubricating oil caused by long-time work of the speed reducer; when the gear is worn, the butterfly springs can automatically push the first bevel gear and the fourth bevel gear to axially move so as to eliminate the gear fit gap caused by friction and wear; and as the vibration reducing blocks are arranged between the inner ring bodies and the outer ring bodies, the gear vibration reduction is realized, the noise can be lowered, and the harm of impact to wheel teeth is prevented.

Description

technical field [0001] The invention relates to a speed reduction device, in particular to a speed reducer. Background technique [0002] The reducer is a transmission device used to convert the high-speed low-torque power output by the electric motor or internal combustion engine into low-speed high-torque output. [0003] The reducer is generally composed of the reducer casing and the gear transmission mechanism arranged in the reducer casing. When the reducer is working, the friction between the meshing gears will generate a lot of heat. In the prior art, the reducer generally passes through the reducer casing. Set lubricating oil to lubricate and cool the meshing gears, but the heat dissipation performance of the existing reducer is poor. The reduction will accelerate the wear of the gears, which in turn will shorten the life of the reducer. [0004] Moreover, during the transmission process of the gear of the reducer, its tooth surface is prone to friction and wear, w...

Problems solved by technology

[0006] In view of this, the object of the present invention is to provide a speed reducer with air cooling, shock absorbing gear and anti-backlash structure to solve the problem of poor heat dissipation of the speed reducer in the prior art, and the temperature of the lubricating oil will rise when the speed reducer works for a long time. The technical problem of high performance decline; and solve the technical problem that the gear gap of the reducer gear in the prior art will increase during long-term use; There is an impact collision between the gears, which makes the noise when the gears mesh and the teeth are prone to breakage
