WIPING CYLINDER DRIVE OF AN INTAGLIO PRINTING MACHINE

摘要

The wiping cylinder drive has a drive shaft (4) which is independent of the wiping cylinder shaft (2) and which, at its end facing away from the wiping cylinder, is connected to the drive member (15) with the aid of a claw coupling (10). Inserted between the adjacent claws of the constantly engaged claw coupling (10) is a gearwheel (20) which is made of elastically deformable material and the teeth (21) of which are in each case inserted positively between the flanks of adjacent claws of the two coupling parts and, in the case of sudden changes in the load torque of the wiping cylinder, function as damping elements. The drive member (15) has a gearwheel (17) which is constantly in engagement kinematically with the gear leading to the main motor of the printing machine.
