Abstract

The invention relates to the technical field of speed reducers, and particularly provides a wave generator, a harmonic reducer and a drive system. The wave generator comprises a cam and a flexible neutral layer, wherein an outer edge outline molded line of the cam comprises a first molded line located in a meshing area and a second molded line located in a non-meshing area; the second molded line is a cosine cam molded line; the first molded line has radial increment compared with the second molded line, so that the polar radius, located in the meshing area, of the cam is increased; and the first molded line and the second molded line are continuously and guidably connected in a transition way. According to the wave generator, the harmonic reducer and the drive system provided by the invention, through increasing the polar radius of the meshing area, the radial deformation amount, in a meshing area, of a flexible wheel is increased, flexible wheel teeth and rigid wheel teeth located at a semi-meshing state are sufficiently meshed, and the meshing tooth number of the meshing area is correspondingly increased, so that the meshing stress of the flexible wheel teeth is reduced, and a bearing capacity of the speed reducer is improved.

Description

technical field [0001] The invention relates to the technical field of reducers, in particular to a wave generator, a harmonic reducer and a transmission system. Background technique [0002] The harmonic reducer is mainly composed of a wave generator, a flexible spline and a rigid spline. The wave generator makes the flexible spline generate controllable elastic deformation waves, and through the interaction with the rigid spline, the transmission of motion and power is realized. The deformation process of the flexspline is symmetrical and harmonic. Different deformed shapes of the flexspline have different working capabilities. The deformed shape of the flexspline depends on the shape of the outer edge of the wave generator. According to different structures, wave generators can be divided into different types of wave generators such as cam type, roller type, and disc type. High efficiency and high efficiency, so the current harmonic reducer mainly uses a cam wave generat...
