A screwdriver arrangement has: a screwdriver housing; a drivetrain, arranged in the screwdriver housing and which comprises a drive housing, a motor in the drive housing, in particular an electric motor, and an output shaft protruding from the drive housing at the axial front face. The axial front end of the output shaft comprises a bit holder for fixing a screw bit or is connectable to such a bit holder for conjoint rotation. A torque-measuring device is connected at one connection point to the screwdriver housing via a torsionally elastic connection element, which comprises the torque-measuring device, and is rotatable in the screwdriver housing. The torque-measuring device detects the output torque of the output shaft as a reaction torque at the connection element. The invention further relates to a method for operating a screwdriver arrangement.
Torque screwdriver arrangement (1) with a screwdriver housing (4), a drive train (5) arranged in the screwdriver housing (4), which drive train (5) has a drive housing (7), a motor (8), in particular an electric motor, arranged in the drive housing (7) and an output shaft (10), which projects out of the drive housing (7) at its axially front end face and whose axially front end comprises a bit holder (11) for fixing a screw bit or can be connected in a rotatably fixed manner to such a bit holder, the torque screwdriver arrangement (1) further having a torque measuring device (16), wherein a support arrangement (13) is provided at exactly one support location (14), via which the reaction torque exerted on the drive housing (7) during operation of the torque screwdriver arrangement (1) is supported on the screwdriver housing (4), and the drive housing (7) is otherwise provided or mounted rotatably in the screwdriver housing (4), and wherein the torque measuring device (16), which is provided in particular on the support arrangement (13), is designed and/or set up to detect the output torque of the output shaft (10) in the form of the supported reaction torque on the support arrangement (13).
