US 12,311,512 B2 · Screwing device, driving torque generating means, screwing system and torque control method

Abstract

A screwing device for applying and/or transmitting a torque to a screw partner and for interacting with a drive torque generating means, including flat output means (6) which have an output that, can be detachably connected to the screw partner and a drive, to which a drive torque can be manually or mechanically applied, an output gearwheel (8) that can be driven by the fiat output means (6), a mechanical interface (46) for selective direct or indirect connection to the drive torque generating means for initiating the torque, a compensation unit (30) which is designed to store and process compensation data and which comprises an output gearwheel-specific torque curve and/or an output gearwheel-specific efficiency curve for calculating it with a value of an actual output torque in order to generate a value of a compensated output torque, and a data interface (36) which is designed to transmit compensation data to a drive torque generating means.
