摘要： A drive disengaging device for a seal-type dampening system in an offset lithographic printing press. The disengaging mechanism includes a clutch gear rotationally mounted on a drive shaft and having a clutch bearing securely mounted thereto. The drive shaft incorporates a specified diameter, on which the clutch bearing functions as designed, and a stepped diameter, on which the clutch bearing does not function as designed. Alternate axial positioning of the clutch bearing between the specified diameter and the stepped diameter causes the clutch bearing to function or not function, respectively, as designed. Gear mesh between the clutch gear and the press drive train is maintained when the clutch gear is in either position. Axial positioning of the gear clutch assembly is controlled by the press operator through an actuator assembly. The actuator assembly can be either an axial-type or rotation-type, depending on the press configuration and space restrictions.

摘要： A dampener activation apparatus is disclosed for engaging and disengaging a dampener with a plate cylinder of a printing press and for engaging and disengaging a drive gear with a roller in the dampener. The drive gear is driven to rotate about a shaft supporting the roller by a press drive train. The drive gear is also axially moveable on the shaft to engage and disengage the form roller. A first actuator is mounted to a dampener side frame and configured to translate the drive gear on the shaft to engage and disengage the form roller. A second actuator is attached to the printing press and configured to engage and disengage the dampener with the plate cylinder. A compressed air supply is in fluid communication with and configured to control the first and second actuators.
