ABSTRACT:
A gear train transmits power to a higher angular speed. A drive pinion has a spur gear design for meshing with a spur toothed portion of an intermediate gear. The intermediate gear also has a helical toothed portion following a path which axially moves toward and away from the circular path of the spur gear portion engaging the pinion gear. A third gear having the same diameter as the pinion gear is adapted to mesh with the helical gear portion of the intermediate gear.
