Embodiment Construction
[0022] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0023] Taking the double-arc tooth shape design of harmonic gear transmission as an example, refer to figure 1 , a bidirectional conjugate tooth profile design method for harmonic gear transmission, comprising the following steps:
[0024] 1) First complete the design of the structural parameters according to the load and other requirements, and then determine the meshing parameters of the tooth shape to be designed; figure 2 As shown, first establish each coordinate system, establish the coordinate system {OXY} of the wave generator, the origin is located at the rotation center of the wave generator, the Y axis coincides with the long axis of the wave generator, and the X axis coincides with the short axis of the wave generator; establish the flexspline Gear tooth coordinate system {o 1 x 1 the y 1}, its y 1 The axis coincides with the center l...
