ABSTRACT:
A variable torque transmission includes at least one disc-shaped gear 30 having a circular toothed surface 36 with flat beveled teeth 32 that mate along radius 38 with the cone-shaped teeth of pinion gear 10 to produce an infinitely variable lever arm and thus infinitely variable torque while allowing a constant rotation ratio between the drive shafts of the flat beveled gear 30 and pinion gear 10. The result is that the drive shaft energy input may be constant and thus energy efficiency may be maximized while torque may be selectively varied.
