Open the CIPO recordAbstract From the Canadian patent
The drive ratio of a planetary gear transmission is controlled by the centrifugal force associated with a rotor assembly having an imbalance that varies as a function of the speed of oppositely rotating eccentric rotor elements relative to a carrier frame mounting planetary gears drivingly connected to a spider on which the rotor assembly is mounted. Reaction gears fixed to the carrier frame control the rotational and phase relationships of the rotor elements on the rotor assembly.
