Abstract

The invention provides a planetary harmonic gear reducer. The planetary harmonic gear reducer comprises a planetary harmonic inner gear ring, a gear frame, a flexible gear ring and an output shaft, wherein rigid inner teeth are arranged on the planetary harmonic inner gear ring; a harmonic coupling part is arranged on one side of the gear frame; the flexible gear ring is arranged in the harmonic inner gear ring; the harmonic coupling part is arranged on the position, corresponding to flexible outer teeth, on the flexible gear ring; the output shaft is provided with an outer gear ring; after being deformed by flexible side teeth or flexile inner teeth, the outer gear ring and the flexible gear ring are meshed with each other; the matching tooth number between the outer gear of the output shaft and the flexible side teeth or flexible inner teeth of the flexible gear ring is equal; the gear frame directly drives the harmonic coupling part to drive the flexible gear ring, so that after being deformed, the flexible gear ring is enabled to be subjected to harmonic meshing with the flexible inner teeth of the planetary harmonic inner gear ring, and meanwhile, after being deformed, the flexible gear ring is meshed with the outer gear ring of the output shaft, so that the output shaft is driven to finish reduction transmission. The working speed of the flexible gear ring is reduced, and the service life of the flexible gear ring is further prolonged.

Description

technical field [0001] The invention relates to the field of reducers, in particular to a planetary harmonic gear reducer. Background technique [0002] The key component of the harmonic gear reducer is the flexible ring gear, which requires high machining accuracy and materials, and the process is also very complicated. The rapid deformation of the flexible ring gear during high-speed operation is prone to fatigue damage, which will reduce the service life. The cost of harmonic gear reducer is very high, and it cannot be widely used in many practical fields. Contents of the invention [0003] The invention provides a planetary harmonic gear reducer with simple structure, low cost, small volume and long service life. [0004] In order to solve the above problems, as an aspect of the present invention, a planetary harmonic gear reducer is provided, including: a planetary harmonic inner ring gear with rigid internal teeth; a transmission frame with a harmonic coupling part...
