Problems solved by technology

Due to the requirements of the current harmonic reducer's own structural strength, the hollow hole of the harmonic reducer is often small. The ratio of the hole diameter of the current harmonic reducer to the length of the reducer is roughly one-half. When the ratio of the aperture to the length of the hollow hole is greater than one-half, for example, when a large number of wires need to be passed through the hollow hole, the existing harmonic reducer cannot meet the assembly requirements under the premise of ensuring the structural strength

Abstract

The invention discloses a harmonic reducer. The harmonic reducer comprises a connecting shell body, an input shaft, a crossed bearing, a flexible bearing, a flexible gear and a rigid gear, a hollow hole is formed in the axis of the input shaft, the flexible bearing is provided with protrusions, the flexible gear is provided with a connecting end and a working end, the working end is arranged on the flexible bearing in a sleeving mode, the connecting end is connected to the crossed bearing, the rigid wheel is arranged between the connecting shell body and the working end in a sleeved mode, theouter ring of the rigid wheel is connected to the connecting shell body, the flexible bearing is arranged between the input shaft and the flexible gear, the outer ring of the flexible bearing is connected with the flexible gear, the inner ring of the flexible bearing is connected with the input shaft, and the protrusions can eject the flexible gear towards the rigid gear so that the rigid gear canmesh with the flexible gear. Due to the fact that the connecting end is connected to the crossed bearing, the working end is arranged on the flexible bearing in a sleeving mode, the flexible bearingis arranged between the input end and the flexible gear, the outer ring of the flexible gear can mesh with the rigid gear, the rigid gear is connected to the connecting shell body, and therefore the length ratio of the hollow hole to the harmonic reducer is increased on the premise that the structural strength of the harmonic reducer is guaranteed.

Description

technical field [0001] The invention relates to the technical field of harmonic reducers, in particular to a harmonic reducer. Background technique [0002] The harmonic reducer is a transmission device for motion and power transmission through the deformation of the flexible spline and the cooperation between the flexible spline and the rigid spline. Due to the requirements of the current harmonic reducer's own structural strength, the hollow hole of the harmonic reducer is often small. The ratio of the hole diameter of the current harmonic reducer to the length of the reducer is roughly one-half. When the ratio of the aperture to length of the hollow hole is greater than 1 / 2, for example, when a large number of wires need to be passed through the hollow hole, the existing harmonic reducer cannot meet the assembly requirements under the premise of ensuring the structural strength. Contents of the invention [0003] The present invention aims to solve at least one of the ...
