Abstract

See full text

A counterbalancing system for continuously variable torque transmissions of the type in which one of two working bodies, between which torque is transmitted by rolling friction, undergoes a nutational movement to generate an inertial couple which is variable with an output speed varying component of the transmission. The system includes a pair of variably positioned counterweights connected for movement directly with the speed varying mechanism of the transmission in a manner such that at least the variable component of the inertial couple is substantially counterbalanced for all speed ratios of the transmission.
