Abstract:
Provided in the present invention are a design method for an inner tooth profile of a complex-wave oscillating-tooth speed reducer, and a two-stage speed reducer. For a time-varying pitch curve meshing form of the contour of an elliptical cam, inner tooth profiles of two stages of transmission are respectively obtained by using a B-matrix kinematic method. A meshing matrix has a uniqueness which does not change along with a change in the form of a conjugate surface, and therefore the calculation of a B matrix is unrelated to a geometric parameter of the conjugate surface, and regardless of an expression of the conjugate surface, the same B matrix can be used for calculation and analysis. Compared with a traditional oscillating-tooth profile design method based on an envelope theory, the calculation process is simplified, the design efficiency and the design precision are improved, and the complexity of subsequent machining is reduced, thereby reducing the machining cost.
