Embodiment Construction

[0018] Such as figure 1 The rolling harmonic reducer shown includes an input end assembly 1, and its special feature is that the periphery of the input end assembly 1 used in the present invention is provided with a bearing assembly. Specifically, in order to have a better meshing effect, an accommodation space is distributed in the middle section of the bearing assembly, and a transmission assembly is sheathed on the periphery of the accommodation space. Correspondingly, an external gear assembly 3 is arranged on the periphery of the transmission assembly. At the same time, an output end assembly 4 is sheathed around the working end of the bearing assembly. Furthermore, considering the stable operation of the present invention, the output end assembly 4 is connected to the external gear assembly 3 through connecting screws 5 .

[0019] As far as a preferred embodiment of the present invention is concerned, in order to realize the output of high torque, the transmission asse...

Abstract

The invention relates to a rolling harmonic speed reducer which comprises an input end assembly. The speed reducer is characterized in that the periphery of the input end assembly is provided with a bearing assembly, the middle part of the bearing assembly is provided with a containing space, and a drive assembly is sleeved on the periphery of the containing space; the periphery of the drive assembly is provided with an external gear assembly, an output end assembly is sleeved on the operating end periphery of the bearing assembly, and the output end assembly is connected with the external gear assembly by virtue of a connecting screw; and an inner gear is doubly meshed with a corresponding external gear, thereby obtaining double torsion outputs, the couple of an integral structure is more balanced, the output is more stable, and the operation of the speed reducer is more stable. Therefore, double cylinders in an internal tooth cavity and a central shaft are manufactured into an integral crank shaft and are easy to control, thereby guaranteeing the working accuracy.

Description

technical field [0001] The invention relates to a reducer, in particular to a rolling harmonic reducer. Background technique [0002] A rolling harmonic reducer (Rolling Harmonious Reducer) referred to as RH reducer. After repeated trials and tests, the circular movement of the small cylinder in the inner wheel cavity can realize the differential tooth meshing of the inner and outer gears, and make them move, so as to carry out tooth-to-teeth mutual meshing with the outer wheel. Because every time the small cylinder turns a full circle, the corresponding point reaches an extreme value, that is, one tooth moves, so as to achieve the effect of deceleration. [0003] However, the existing rolling harmonic reducer has a low matching degree and unstable output, which leads to unstable working conditions as a whole. Furthermore, the rigidity of the overall parts is small, which affects the service life of the bearings in the reducer. Contents of the invention [0004] The obj...
