Abstract
The variable speed gear ratio transmission apparatus of the present invention provides input differential means for dividing an input rotational force into two rotational components, output differential means for combining the divided component rotational forces, input and output shafts geared to the respective differentials, and a variable load inhibitor mechanism coupled to one of the divided rotational components for varying its rotational speed, thereby reciprocally varying the magnitude of the other divided rotational component, with the result of providing an infinite selection of speeds between the operative speed limits of the apparatus. The variable load inhibitor mechanism preferably includes planetary gears connected by brackets, each separately engaging a stationary ring gear, one of which planetary gears is geared to the input divider differential and the other of which is geared to means for determining the load to be placed on the variable load inhibitor mechanism.
