Speed reduction drive device with damping, lubricating, cooling and air pressure balancing functions

Abstract

The invention discloses a speed reduction drive device with damping, lubricating, cooling and air pressure balancing functions. The speed reduction drive device comprises a speed reducer shell, a cylindrical gear drive mechanism, an oil gathering device, a lubricating oil circulating cooling device and an automatic exhaust valve. A gear of the cylindrical gear drive mechanism comprises an inner ring body, an outer ring body and a damping block. The oil gathering device comprises an annular pipe body and a partition plate. The lubricating oil circulating cooling device comprises an oil pump and a radiator. The damping block elastically deforms to achieve gear damping, noise generated in the gear engaging process can be lowered, and the gear breakage problem can be solved. Lubricating oil is brought to a gear engaging region to lubricate the gear through the oil gathering device, and the lubricating and cooling effect of the gear can be improved. The lubricating oil is pumped out to be cooled through the lubricating oil circulating cooling device, so that the problem that the temperature of the lubricating oil rises can be solved. The inner air pressure and the outer air pressure of the speed reducer shell are balanced through the automatic exhaust valve, and the problem of lubricating oil leakage caused by increase of the inner air pressure of the speed reducer shell can be solved.

Description

technical field [0001] The invention relates to a speed reduction device, in particular to a speed reducer. Background technique [0002] The reducer generally uses lubricating oil to lubricate and cool the gears. Too much lubricating oil in the reducer housing will easily lead to lubricating oil leakage, and too little will easily lead to poor lubrication effect. Therefore, the adding position of lubricating oil in the reducer is generally in the gear One-third to one-half of the lower half, and the gear meshing part is the teeth near the middle of the gear, and the lubricating oil level in the reducer housing is lower than the meshing teeth, so the gear lubrication is the The lubricating oil that is thrown to a high place when the gear rotates, that is, the gear lubrication of the existing reducer adopts the mode of splash lubrication, and the gear lubrication effect is relatively poor. [0003] Moreover, the gears of the reducer in the prior art do not have a shock-absor...

Problems solved by technology

[0006] In view of this, the object of the present invention is to provide a reduction transmission device with the functions of shock absorption, lubrication, cooling and air pressure balance, so as to solve the problem that the gears in the reducer in the prior art use splash lubrication and the gear lubrication and cooling effects are relatively poor. Poor technical problems; and solve the problem that the gears of the reducer in the prior art do not have a shock absorbing structure, and there is an impact collision between the gears when the gears mesh, making the noise larger and the teeth prone to fracture when the gears mesh; and solving the problems of the prior art The heat dissipation performance of the medium reducer is poor, and the temperature of the lubricating oil in the reducer rises greatly, which easily leads to the technical problem of damage to the transmission mechanism of the reducer; and solves the technical problem of the leakage of the lubricating oil due to the increase in the internal air pressure of the reducer
