Coupling device for coupling and decoupling plate cylinder of processing machine i.e. sheet fed rotary printing machine, with/from electric motor, has coupling half that is supported at toothed wheel in axially movable manner
Coupling device for coupling and decoupling plate cylinder of processing machine i.e. sheet fed rotary printing machine, with/from electric motor, has coupling half that is supported at toothed wheel in axially movable manner
The device has a coupling half and a toothed wheel with another coupling half that is arranged on a cylinder pivot of a cylinder (11). The toothed wheel is arranged in a freely rotatable manner, where the other coupling half is supported at the toothed wheel in an axially movable manner and in a torque-proof manner. The other coupling half is arranged in a housing of the toothed wheel, where the housing is designed as a working cylinder. A circular working piston is arranged in the working cylinder, where the piston carries the other coupling half.
