TOOTH PROFILE DESIGN METHOD FOR THREE-DIMENSIONAL HIGH-RIGIDITY HARMONIC SPEED REDUCER

WIPO Patent Application WO/2017/215621

A1

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.
