Abstract:
In this paper, the gearing principle of the spherical hob is
introduced. A new definition of lead has been given. It explains the
method of the formation and evolution of the spherical helicoidal
surface. The helical surface equations of the spherical hob are set up
in spherical coordinates. The formulas of the side clearance angle and
the calculation are given.
