ABSTRACT:
A type of internal cycloidal gearing based on the principal that different size generating circles rolling inside a directing circle which has a diameter equal to the sum of the diameters of the generating circles generate identical hypocycloids, and, similarly, a generating circle that surrounds a directing circle and gyrates around it like a "hula-hoop" generates the same epicycloid as a small circle having a diameter equal to the difference in the diameters of the surrounding "hula-hoop" circle and the directing circle.
