ABSTRACT:
A mechanism for damping vibration in the gear drive of a rotary printing press is disclosed. The various gear driven elements such as transfer cylinders, forme cylinders and blanket cylinders carry belt pulleys with the pulleys being connected by suitable belts. The sizes of the pulleys are selected and sized to attempt to drive the various cylinders at a speed less than the speed provided by the gear drive. In this way the gear drive is not allowed to chatter or vibrate. The orientation of the drive belts is selected to conform with the number of gears in a particular gear drive assembly.
