Abstract

Es wird ein fluidbetätigter Drehantrieb vorgeschlagen, der ein Antriebsgehäuse (1) aufweist, an dem eine zu einer Drehbewegung antreibbare Abtriebswelle drehgelagert ist, an der ihrerseits eine aus dem Antriebsgehäuse (1) herausragende mitdrehende Steuerpartie (14) vorgesehen ist. Die Steuerpartie (14) arbeitet mit einer Positionserfassungseinrichtung (23) zusammen, die eine Positionierung der Abtriebswelle (3) in bestimmten Drehwinkelpositionen ermöglicht und die einen fest mit dem Antriebsgehäuse (1) verbundenen Grundkörper und einen an dem Grundkörper (32) drehbar gelagerten Drehkörper (35) aufweist. An dem Drehkörper (35) ist eine unkreisförmig profilierte erste Kupplungspartie (52) und an der Steuerpartie (14) eine zu der ersten Kupplungspartie (52) koaxiale, unkreisförmig profilierte zweite Kupplungspartie (53) vorgesehen, die über ein Kupplungsteil (51) miteinander verbunden sind, das zum Ausgleich von Fluchtungsfehlern zwischen den Längsachsen der Kupplungspartien (52, 53) zumindest teilweise als Elastikkörper ausgebildet ist.
