Abstract (en)
[origin: WO2006100032A1] In order to test screwing devices (20) with a rotating unit (21) and with a first torque sensor (23), a testing unit (2) with a counter-torque generating device (3) and with a second torque sensor (5) is provided, this test unit being able to be brought into contact with the rotating unit (21) of a screwing device (20) in an starting rotation position of the rotating unit (21). A control unit (22) controls a rotation of the rotating unit (21) brought into contact with the testing unit until the first torque sensor (23) reaches a predetermined set torque. The second torque sensor (5) measures an actual torque caused by the rotation of the rotating unit (21), and a comparison unit (6) compares the predetermined set torque of the screwing device (20) with the actual torque measured by the second torque sensor (5). The control unit (22) is designed for rotating the rotating unit (21) back beyond the starting rotating position about a predetermined angle into another starting rotation position. The functional components located inside the screwing device are brought together in a defined position different from the position in which they stood together during the testing of the first operating point of the screwing device. This enables an effective and reliable testing of the screwing device.
