Problems solved by technology

[0003] In the prior art, if the reduction ratio of the harmonic reducer is designed to be large, the volume of the harmonic reducer will be relatively large, which is not conducive to the installation of the harmonic reducer and limits the harmonic deceleration device usage scenarios
If the volume of the harmonic reducer is designed to be small, then the harmonic reducer often has a small reduction ratio, which also limits the applicable scenarios of the harmonic reducer

Abstract

The invention belongs to the technical field of speed reducers, and particularly relates to two-stage harmonic speed reduction equipment. The two-stage harmonic speed reduction equipment comprises a first-stage harmonic speed reducer and a second-stage harmonic speed reducer, wherein the first-stage harmonic speed reducer comprises a first-stage wave generator, a first-stage flex spline and a first-stage circular spline connected to the first-stage flex spline in a sleeving manner; the first-stage flex spline is connected to the first-stage wave generator in a sleeving manner; the second-stage harmonic speed reducer comprises a second-stage wave generator, a second-stage flex spline and a second-stage circular spline connected to the second-stage flex spline in a sleeving manner; the second-stage flex spline is connected to the second-stage wave generator in a sleeving manner; the first-stage circular spline is connected to the second-stage flex spline; and the first-stage circular spline is connected to the second-stage wave generator. The two-stage harmonic speed reduction equipment has the advantages of being relatively large in speed reduction ratio, small in axial size, light in weight and the like, and the practicability and applicability of the two-stage harmonic speed reduction equipment are improved.

Description

technical field [0001] The invention belongs to the technical field of reducers, in particular to a second-order harmonic reduction device. Background technique [0002] The harmonic reducer is mainly composed of a rigid wheel with an inner ring gear, a flexible wheel with an outer ring gear, and a wave generator; among them, the rigid wheel is equivalent to the sun gear in the planetary gear system, and the flexible wheel is equivalent to the planetary gear The planetary gear in the system, the harmonic generator is equivalent to the planetary carrier in the planetary gear system. The harmonic reducer has a simple structure and a small volume, and is widely used in robots. [0003] In the prior art, if the reduction ratio of the harmonic reducer is designed to be large, the volume of the harmonic reducer will be relatively large, which is not conducive to the installation of the harmonic reducer and limits the harmonic deceleration device usage scenarios. If the volume o...
