ABSTRACT:
A transmission unit is provided for converting torque to angular velocity and angular velocity to torque using angular momentum. The conversion is automatically accomplished in a stepless fashion using inertial masses which, preferably, move along spherical paths. The transmission unit apparatus is coupled to a source of power. When the transmission unit is driven by the source of power about a primary axis, the radii-of-gyration of the inertial masses cyclically change to supply torque impulses of angular momentum change to an output shaft load. The torque impulses of angular momentum change, in conjunction with the concomitant, inherent, time-rate-of-change of rotational kinetic energy, automatically convert to torque/angular velocity ratios. The magnitude of the output torque and the magnitude of the output angular velocity depend upon the power source characteristics but, more particularly, upon the output load conditions.
