General reducer with eccentric engagement pairs

Abstract

The invention discloses a general reducer with eccentric engagement pairs, comprising a shell, a power input shaft and a power output shaft, wherein an eccentric sleeve is fixedly arranged in the circumferential direction of the power input shaft, is engaged with engaging coggings on the shell by one-to-one correspondence through engaged teeth and is engaged with external gears on the power output shaft in small teeth difference through internal gears. The power input mechanism of the invention adopts the engagement pairs without teeth difference, which is similar to spline engagement, therefore, the relative autorotation speed of the engaging coggings and the engaged teeth is zero and autorotation of a driving fluted disc is eliminated, thus eliminating the high-frequency waves generated in the driving process of the reducers with small teeth different in the prior art, avoiding unnecessary additional motion, improving the driving efficiency and ensuring the motion to be output without hindrance. The general reducer has fewer components than the cycloidal pinwheel reducers in the prior art and has simple and compact structure, small volume and low cost.

Description

technical field [0001] The invention relates to a deceleration device, in particular to a universal decelerator with an eccentric meshing pair. Background technique [0002] The reducer is a device that reduces the high speed of the power machine to the speed suitable for the working machine, and is widely used in the equipment industry. With the development of the equipment industry, higher requirements are put forward for the reducer. The multi-stage gear reducer is widely used in the prior art. The multi-stage gear reducer uses multiple sets of gear meshing pairs to fit the transmission ratio. When the reduction ratio is required to be slightly larger, its structure is complicated and the volume is also large; The gear reducer can obtain a large reduction ratio, but it needs to arrange multiple sets of gears and gear shafts in the radial direction, the structure is relatively complicated, and the structural arrangement is difficult and the volume is large. In order to s...

AI Technical Summary

Problems solved by technology

Due to the cycloidal wheel in the prior art has two kinds of motions, revolution and rotation, part of the motion cannot be used for transmission, resulting in useless high-frequency waves, motion interference or other additional motions, resulting in the transmission of the small tooth difference reducer. The efficiency is low or the power cannot be output
