Abstract
Cam-oscillating drive which operates to compensate for the cyclically occurring variations in the course of the drive moment by means of at least one cam disc mounted on the drive shaft and a rolling cam follower in engagement with the cam disc, wherein the cam follower has an oscillating part with an oscillating mass driven by the cam follower, and wherein the oscillating part has a curved section that cooperates with a curve roller and a potential energy storage such that the kinetic energy of the oscillating part is stored in the potential energy storage during the deceleration phase, while during the acceleration phase the energy is again drawn from the potential energy storage.
