Verfahren und Vorrichtung zum Erkennen einer fehlerhaften kraft- oder formschluessigen Verbindung

DE 102006047683 B3 UPAB: 20080421 NOVELTY - The method involves moving a screw (3) and a clamping section (1), and/or a counter piece (2) relative to each other and provided in force or form-fitting contact such that a screw connection is force-balanced and/or a form-fit is partially released. A torque or force characterizing the connection is measured as a parameter during a relative movement between the screw and the section, and/or the piece and is compared with a reference parameter. A friction force path or a friction moment path is determined between the screw and the clamping section, and/or the counter piece. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a device for recognizing a defective force or form-fitting connection i.e. screw connection. USE - Method for recognizing a defective force or form-fitting connection i.e. screw connection, by an on-screwing device. ADVANTAGE - The torque or force characterizing the screw connection is measured as the parameter during relative movement between the screw and the clamping section, and/or the counter piece and is compared with the reference parameter, thus automatically recognizing the defective force or form-fitting screw connection in a reliable manner during disassembling of the connection
