Abstract

Die Erfindung betrifft einen hohlzylinderförmigen Ultraschallaktor 1 mit einer zentralen Achse ZA, einer der zentralen Achse zugewandten inneren Umfangsfläche 2 und einer der zentralen Achse abgewandten und von der inneren Umfangsfläche beabstandeten äußeren Umfangsfläche 3, wobei in einem zur zentralen Achse senkrechten Querschnitt die innere Umfangsfläche eine geschlossene, innere Umrisskurve 4 und die äußere Umfangsfläche eine geschlossene, äußere Umrisskurve 5 definiert, und an der inneren Umfangsfläche und der äußeren Umfangsfläche jeweils wenigstens eine Elektrode 6,7 angeordnet ist, und sich zwischen gegenüberliegenden Elektroden ein elektromechanisches Material befindet, und durch elektrische Ansteuerung der Elektroden der Ultraschallaktor zu Schwingungsdeformationen anregbar ist, die zum Antrieb eines mit dem Ultraschallaktor in Friktionskontakt 9 stehenden Elements nutzbar sind. Die Erfindung zeichnet sich dadurch aus, dass in einem nicht-angeregten Zustand des Ultraschallaktors die Krümmung der inneren Umrisskurve und/oder der äußeren Umrisskurve wenigstens drei voneinander beabstandete lokale Maximalstellen aufweisen/aufweist. Zudem betrifft die Erfindung die Anordnung eines solchen hohlzylinderformigen Ultraschallaktors an einer Halterungsvorrichtung. Außerdem betrifft die Erfindung die Verwendung eines solchen hohlzylinderformigen Ultraschallaktors in einem Antrieb.
