Title:
VARIABLE SPEED POWER TRANSMISSION
Document Type and Number:
WIPO Patent Application WO2001044682
Kind Code:
A9
Abstract:
A continuously variable speed power transmission includes a rotatable input member (11), a rotatable output member (17) including rearwardly directed output face cams. A reaction control rotor (14a) mounted for selective rotation about the input axis includes forwardly directed reaction face cams (28) in opposition to the output face cams. A pericyclic motion converter (19) rotatably mounted for nutational motion about the input axis includes load transmitting follower members simultaneously engageable with the output face cams and with the reaction face cams. A control mechanism selectively adjusts the rate of rotation of the reaction control rotor relative to the input member such that the relative rotation results in both rotation and nutation of the pericyclic 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.
