Abstract:
A continuously variable speed power transmission comprising:an input member rotatable about an input axis; an output member rotatable about an output axis including a plurality of rearwardly directed output rotor external face gear teeth thereon; a conjugate reaction control rotor with integrated motor/generator components mounted for selective rotation about the input axis including a plurality of forwardly directed reaction external face gear teeth thereon in opposition to the output external face gear teeth on the output member; a conjugate motion converter with internal face gear teeth having pitch angles greater than 90 degrees embodied on both sides thereon and rotatably mounted for nutational and rotational motion about the input axis that are simultaneously engageable with the output rotor external face gear teeth and with the reaction rotor external face gear teeth; and control means for selectively adjusting the rate of rotation of the reaction control rotor relative to the input member; whereby relative rotation between the reaction control rotor and the input member results in both rotation and nutation of the conjugate motion converter about the input axis and thereby results in a continuously variable change of ratio of the rotational speed of the output member relative to the input member.
