Problems solved by technology

[0003] Although some existing planetary harmonic reducers increase the reduction ratio, they have a large length in the axial direction. In practical applications such as robot joints, a reducer with a smaller axial length is needed.

Abstract

The invention discloses a planetary harmonic composite speed reducer. The speed reducer comprises a flange cover body, and a first steel wheel is arranged on the outer surface of one side of the flange cover body. According to the planetary harmonic composite speed reducer, a first-stage speed reduction system is composed of a first sun gear, a planet gear, a planet carrier, a second sun gear and a flexible gear, the first sun gear serves as an input shaft, and the second sun gear is an inner gear. The planet gear is meshed with inner teeth of the first sun gear and the second sun gear simultaneously. The planet carrier is used for mounting the planet gear. The first sun gear, the planet gear, the planet carrier and the second sun gear serve as a wave generator. The second sun gear is embedded into the flexible gear, and a bulge is arranged at the engaged part of the planet gear and the second sun gear, so that the second sun gear and the flexible gear expand and deform outwards and are engaged with a first steel gear. The wave generator, the flexible gear, the first steel gear and a second steel gear form a second-stage speed reduction system, the speed reduction ratio of an existing harmonic speed reducer is increased, and the axial length of the speed reducer is obviously reduced through a double-steel-gear structure.

Description

technical field [0001] The invention belongs to the field of reducers, and in particular relates to a planetary harmonic compound reducer. Background technique [0002] Compared with the traditional reducer, the harmonic reducer has the advantages of high precision, large torque, large reduction ratio and simple structure. With the development of technology, there is an urgent need for a reducer with little change in volume but a significant increase or decrease in the reduction ratio. In this context, a planetary harmonic compound reducer is also a hot topic at present. [0003] Although some existing planetary harmonic reducers increase the reduction ratio, they have a large length in the axial direction. In practical applications such as robot joints, a reducer with a smaller axial length is needed. Contents of the invention [0004] Therefore, the present invention provides a planetary harmonic compound speed reducer to solve the problems in the prior art. [0005] I...
