Abstract

Die Erfindung bezieht sich auf eine Antriebsvorrichtung (19) für einen Federspeicher (17) eines elektrischen Schalters, die einen Motor (21), eine durch den Motor (21) in einer Spann-Richtung (33) drehbare Antriebswelle (22), eine an die Antriebswelle (22) gekoppelte Kurvenscheibe (24), an deren Kontur während einer Spannphase des Federspeichers (17) ein an den Federspeicher gekoppeltes Spannelement (35) antreibbar ist, und zumindest eine an die Antriebswelle (22) gekoppelte Steuerscheibe (26) zur Steuerung des Motors (21) umfasst.The invention relates to a drive device (19) for a spring accumulator (17) of an electrical switch, the one motor (21), one by the motor (21) in one Clamping direction (33) rotatable drive shaft (22), one to the Drive shaft (22) coupled cam (24), on the Contour during a tensioning phase of the spring accumulator (17) Clamping element (35) coupled to the spring accumulator and at least one coupled to the drive shaft (22) Control disc (26) for controlling the motor (21) comprises.

Um die motorische Antriebskraft für mehrere Spannzyklen des Federspeichers - insbesondere durch Vermeiden von Motorschäden - sicher zur Verfügung zu stellen, sind die Kopplungen von Kurvenscheibe (24) und Steuerscheibe (26) mit der Antriebswelle (22) derart gestaltet, dass nach Durchlaufen der Spannphase die Kurvenscheibe (24) in der Spannrichtung (33) der Steuerscheibe (26) wenigstens ein Stück weit voreilen kann.

Figure 00000001
In order to make the motor drive force available for several clamping cycles of the spring accumulator - in particular by avoiding motor damage - the couplings of the cam disc (24) and control disc (26) with the drive shaft (22) are designed in such a way that after passing through the clamping phase the Cam (24) in the clamping direction (33) of the control disc (26) can advance at least a little.
