Abstract (en)

The transfer system in a press line has at least one transfer unit (12,14) with a number of independent drives powered in the direction of at least one axis. On a failure of one of the drives, the coupling (37) between them prevents a direct stalling at the failed unit. The coupling gives a zone of reduced torque transmission, and only comes into play when one of the drives no longer delivers a sufficient power output.

Abstract (de)

Eine Transfereinrichtung 1 weist wenigstens ein Transfermittel 12, 14 auf, das mit mehreren voneinander unabhängigen Antrieben 17, 18 in Richtung wenigstens einer Achse C, O angetrieben wird. Um bei Ausfall eines Antriebs 17, 18 ein unmittelbares Stehenbleiben von Teilen des Transfermittels zu verhindern, sind die Antriebe 17, 18 über eine Kupplungseinrichtung 37 miteinander gekuppelt. Diese weist einen Arbeitsbereich geringer Drehmomentübertragung auf, der normalerweise eingenommen und nur dann verlassen wird, wenn einer der Antriebe 17, 18 keine ausreichende Antriebsleistung mehr liefert. <IMAGE>
