Embodiment Construction
[0026] Further describe the present invention below in conjunction with embodiment and accompanying drawing thereof:
[0027] The present invention has a cup-shaped harmonic gear with three arc tooth profiles (see attached figure 1 , 2 ), consisting of rigid wheel 1, flexible wheel 2, wave generator 3 and flexible bearing 4. The wave generator 3 is equipped with a flexible bearing 4; after the wave generator 3 is installed in the flexspline 2, the cross section of the flexspline becomes elliptical, and the teeth of the flexspline 2 and rigid spline 1 are completely meshed in the long axis area. Complete detachment of the minor axis region; figure 2 Projection from the end shows fully engaged - fully disengaged meshing state.
[0028] The present invention has the tooth profile design method (tooth profile design method for short) of three-arc tooth profile harmonic gear, the three-arc tooth profile (refer to image 3 ), which consists of the upper arc segment AB on the to...
