CONCLUSION
In this paper, a mathematical model of the ZK-type worm gear set has been developed, in which
the worm gear is cut by an oversize worm-type hob cutter. If an oversize hob cutter is reground
to a smaller pitch diameter, the contact contour of the generated worm gear set will be spread over
a thinner and longer contact area, which looks like the path of contact line as shown in Figs 6
and 7. This result matches the fact that when the pitch diameter of the oversize hob cutter is
decreased to equal that of the worm, line contact will occur. In this case, the worm gear set becomes
a conjugate kinematic pair rather than a pseudo-conjugate gear pair. If a larger center distance is
given, the contact path will be shifted upward and move toward the entry side of worm gear
surfaces, as shown in Fig. 8. Conversely, if a smaller center distance is given, the contact path will
be shifted downward and move toward the exit side
