Abstract

Disclosed is a tooth profile design method for a three-dimensional high-rigidity harmonic speed reducer. The harmonic speed reducer comprises a wave generator (4), a rigid gear (2) and a flexible gear (3). The rigid gear (2) is engaged with the flexible gear (3). The wave generator (4) is in contact with an inner wall of the flexible gear (3). Both the rigid gear (2) and the flexible gear (3) are involute gears. The tooth number of the rigid gear (2) is Z1, and the tooth number of the flexible gear (3) is Z2, where Z1 - Z2 = 2. The modification coefficient of the rigid gear (2) is x1, the modification coefficient of the flexible gear (3) is x2, where x1 < x2, and the modification difference is Δx = x1 - x2. Material removing and profile modification are performed on two sides or the top of the addendum circle of the rigid gear (2) and / or the flexible gear (3). The implementation of the tooth profile design method is convenient, the machining cost is lower, the purpose of large-area engagement is achieved, the torsional deformation resistance and bearing capacity of the harmonic speed reducer are improved, and the service life of the harmonic speed reducer is prolonged.

Description

technical field [0001] The present application generally relates to the technical field of harmonic reducers, and in particular to a tooth profile design method of a three-dimensional high-rigidity harmonic reducer. Background technique [0002] Rigidity is an important index to evaluate the performance of the harmonic gear reducer. Good rigidity means that the harmonic gear reducer has good resistance to torsional deformation, large carrying capacity and long service life. [0003] At present, there are mainly the following methods for improving the rigidity of the harmonic gear reducer: [0004] (1) Improve the gear strength by changing the gear material. Chinese patent document CN201180014539.7 discloses a technical solution for improving the strength of the gear by heat-treating the flexspline of the harmonic gear reduction device to change the metal crystal phase structure. Chinese patent document CN201410372571.8 discloses that by changing the composition and ratio o...
