Embodiment Construction
[0032] Below in conjunction with accompanying drawing, the present invention will be further described by embodiment, and the principle of this method is very clear to those skilled in the art.
[0033] center distance a 1 =125.2, transmission ratio i 01 =33, inclination angle of parent plane b=10°, radius of worm pitch circle r 1 =27.5, base circle radius r b =37.5, number of surrounding teeth is 3.5, indexing circle pressure angle a=22.33°, working half angle j w =16.64°, tooth pitch angle t=10.91°, worm addendum arc radius R a1 =94.51, worm tooth root arc radius R f1 =104.08 right-handed plane enveloping toroidal worm as an example. According to the principle of gear meshing and the homogeneous coordinate transformation matrix, the tooth surface equation of the worm is shown in the following equations:
