Four-stage driving combined type speed reducer and speed reduction method thereof

Abstract

The invention relates to a four-stage driving combined type speed reducer and a speed reduction method thereof. The four-stage driving combined type speed reducer with small teeth difference is a bevel gear-planetary-parallel shaft-four-stage drive with small teeth difference and structurally comprises an input gear pair, a middle planetary gear pair, a parallel shaft gear pair, an output gear pair with small teeth difference, a box body and an end cover. The principle of the speed reduction method of the four-stage driving combined type speed reducer with small teeth difference is that the speed reduction of the speed reducer is realized through a first-stage driving bevel gear drive, a second-stage planetary gear drive, a third-stage driving parallel shaft drive and a fourth-stage driving drive with small teeth difference. The invention has the advantages that the transmission speed ratio and the output torque of the vertical speed reducer are greatly improved, and the bearing capacity and the overload capacity are strong; and the vibration noise is low, the heat dissipation is rapid, the gear machining precision is improved, the machining precision can be ensured easily, the volume and the weight of the entire speed reducer are reduced, the manufacturing cost of the large-power vertical speed reducer is greatly reduced and the production cycle is shortened.

Description

technical field [0001] The invention relates to a speed reducer and a speed reduction method thereof, in particular to a four-stage transmission compound speed reducer and a speed reduction method thereof. Background technique [0002] The multi-stage transmission reducer has the advantages of compact structure, large transmission ratio, multi-tooth meshing, and good overload performance.

Problems solved by technology

Through theoretical analysis and experiments, it is proved that the current ring reducer has the disadvantages of vibration, noise, temperature rise and early damage of the bearing in the actual use process, the output mechanism is increased, the efficiency is reduced, the manufacturing cost is increased, and the bearing capacity is not strong. In particular, the problem of the reducer is more prominent under the conditions of continuous operation, heavy load, high speed and large transmission ratio, which greatly affects its popularization and application.
