SCREWING APPARATUS

Abstract: the invention relates to a screwing apparatus for setting a screw. the screwing apparatus comprises a rotary drive for rotationally driving the screw, a feed drive for generating an axial feed force on the screw, and a shaft-hub unit comprising a drive shaft, which has a non-circular cross-section, and a hub rotationally fixedly connected to the drive shaft. the drive shaft and the hub serve to transmit a torque provided by the rotary drive. in this respect, the drive shaft and the hub are axially displaceable relative to one another within a first torque load range to allow an axial feed movement of the screw relative to the rotary drive. to reduce wear at the shaft-hub unit, a compensating coupling is provided that allows a joint axial movement of the shaft and the hub relative to the rotary drive when a torque load exceeds the first torque load range.
