Abstract

The present invention belongs to the field of speed reducers, especially a harmonic transmission deceleration mechanism. Aiming at the existing problems, the following scheme is proposed, which includes rigid gears, flexible gears and anti-displacement covers, and the rigid gears are respectively provided with two grooves, and the inner walls of the two grooves close to each other are provided with arc-shaped grooves, the inside of the anti-displacement cover is provided with cavities, and the inner walls on both sides of the cavity are provided with L-shaped holes, so An L-shaped rod is rotated on the inner wall of the top side of the L-shaped hole, and the bottom end of the L-shaped rod extends into the arc-shaped groove. There are long grooves on the inner wall of the flexible gear. The invention solves the shortcomings of the prior art, so that the flexible gear and the rigid gear will not be misaligned when they rotate. At the same time, the worn outer ring gear on the flexible gear is also convenient for replacement. Meet people's needs.

Description

technical field [0001] The invention relates to the technical field of reducers, in particular to a harmonic drive reduction mechanism. Background technique [0002] At present, with the advancement of science and technology, reducers are increasingly widely used in various fields. Among them, the harmonic reducer is a new type of reducer developed by using the principle of planetary gear transmission, and adopts the principle of harmonic gear transmission. [0003] The patent with the application number CN201910440382.2 discloses a harmonic transmission reduction mechanism, including a wave generator, a flexible gear, a connecting pin, a rigid gear and an output plate; The accommodation space of the flexible gear; the wave generator includes a cam and a cam bearing sleeved on the outside of the cam. The flexible gear is sleeved on the outside of the cam bearing. The outer ring gear of the flexible gear meshes with the inner ring gear of the rigid gear. A set of waist-shape...
