Abstract

An apparatus for transmitting a torque from a drive shaft for a component of a printing machine to a hollow body surrounding the drive shaft, includes a coupling configuration. The coupling configuration is formed through the use of driver elements, engages in a longitudinally displaceable manner on the drive shaft and couples the latter to the hollow body. In order to use such an apparatus for torques which are not constant, according to a first variant, the coupling configuration includes a coupling ring surrounding the drive shaft, a first subgroup of driver elements coupling the drive shaft to the coupling ring, and a second subgroup of driver elements coupling the coupling ring to the hollow body. According to a second variant, the driver elements couple the drive shaft directly to the hollow body and are resilient in an at least substantially radial direction and in the circumferential direction of the drive shaft, relative to an axis of rotation of the drive shaft. A sheet-processing printing machine is also provided.
