A two-stage integrated planar movable gear reducer based on guide frame coupling

Abstract

The invention discloses a two-stage integrated plane oscillating tooth speed reducer based on guiding frame coupling. A guiding frame is designed through integration of first-stage power output and second-stage power input, in first-stage transmission, a wave generator and an input shaft are designed into a wave exciter of an integrated concentric structure, a first-stage oscillating tooth carrieris fixed, the wave exciter is arranged at the input end of the first-stage oscillating tooth carrier, and the guiding frame is arranged at the output end of the first-stage oscillating tooth carrier,in second-stage transmission, a shaft-type output structure and a disc-type output structure can be designed according to the actual engineering requirements, as for the shaft-type output structure,a second-stage center wheel A is fixed, a second-stage oscillating tooth carrier A drives an output shaft to output power; and as for the disc-type output structure, a second-stage oscillating tooth carrier B is fixed, and a second-stage center wheel B outputs power. The two-stage integrated plane oscillating tooth speed reducer is stable in transmission, flexible and reliable, and has the advantages of good self-balancing performance, compact structure and the like.

Description

technical field [0001] The invention relates to a movable tooth transmission device, in particular to a dual-stage integrated planar movable tooth reducer based on guide frame coupling. Background technique [0002] With the continuous development of movable tooth transmission, many new movable tooth reducers have come out one after another. The patent application number is CN201510629776.4, which is a movable tooth cam mechanism output through the swing plate. By changing the tooth profile curve of the closed groove of the swing plate, it can realize The constant speed input is converted into various forms of swing cam output motion. Through multi-stage series connection, although a large reduction ratio transmission can be realized, the size of the mechanism is significantly increased, and it is not suitable for applications in fields such as drilling platforms and robot joints that are limited by space size. In China, especially with the rapid development of science and t...

[0002] With the continuous development of movable tooth transmission, many new movable tooth reducers have come out one after another. The patent application number is CN201510629776.4, which is a movable tooth cam mechanism output through the swing plate. By changing the tooth profile curve of the closed groove of the swing plate, it can realize The constant speed input is converted into various forms of swing cam output motion. Through multi-stage series connection, although a large reduction ratio transmission can be realized, the size of the mechanism is significantly increased, and it is not suitable for applications in fields limited by space size such as drilling platforms and robot joints. In China, especially with the rapid development of science and technology, there is an urgent need for a new type of transmission device with small size, light weight and large transmission ratio. The planar movable tooth reducer is a representative transmission type in the movable tooth transmission. The raceway on the end face of the gear and the center wheel is processed in the plane, and the manufacturing process is good, but the transmission of the single-stage planar movable tooth reducer is relatively small. If multiple single-stage planar movable tooth reducers are connected in series, although large transmission can be achieved ratio, but the axial dimension is large and the application is limited. Therefore, a two-stage integrated planar movable tooth reducer with the advantages of a planar movable tooth reducer and a small axial dimension can be developed while achieving a large transmission ratio. The reducer can be applied to the development needs of more new technologies and new equipment
