SCREWING DEVICE

The invention relates to a screwing device for setting a screw. The screwing device comprises a rotary drive for rotating the screw, an advancing drive for generating an axial advancing force on the screw, and a shaft/hub unit comprising a driveshaft, which has a non-round cross-section, and a hub,...

Beschreibung
Zusammenfassung:	The invention relates to a screwing device for setting a screw. The screwing device comprises a rotary drive for rotating the screw, an advancing drive for generating an axial advancing force on the screw, and a shaft/hub unit comprising a driveshaft, which has a non-round cross-section, and a hub, which is rotationally fixed to the driveshaft. The driveshaft and the hub are used to contribute to a torque provided by the rotary drive. In the process, the driveshaft and the hub are movable relative to each other within a first torque loading range in order to allow an axial advancing movement of the screw relative to the rotary drive. In order to reduce the wear in the shaft/hub unit, a compensation coupling is provided which allows a common axial movement of the shaft and the hub relative to the rotary drive in the event of a torque load which is increasing over the torque loading range.
