Abstract

Es wird ein Aktuator zum Spannen und Entspannen eines flexiblen Kraftübertragungselements (3) mit einem Zylinder (2) mit konkaver Grundfläche vorgeschlagen, wobei eine Mantelfläche des Zylinders (2) zum Aufwickeln des flexiblen Kraftübertragungselements (3) ausgestaltet ist und ein Ende des flexiblen Kraftübertragungselements (3) an der Mantelfläche befestigbar ist und wobei der Zylinder (2) um eine Drehachse (6) drehbar ist. Weiterhin sind Mittel (5) zur Erzeugung eines Drehmoments und Mittel (1, 4) zur Übertragung des Drehmoments auf den Zylinder vorgesehen. Der Aktuator zeichnet sich dadurch aus, dass ein minimaler Krümmungsradius einer Grundfläche des Zylinders größer ist als ein minimaler Abstand der Mantelfläche des Zylinders (2) zu der Drehachse (6). Hierdurch wird die Übertragung einer großen Kraft bei gleichzeitig relativ geringer Biegebelastung des flexiblen Kraftübertragungselements (3) erreicht.
