Abstract

Die Erfindung betrifft ein axiales Federelement (6) mit zwei zueinander in axialer Richtung beabstandeten umlaufenden Ringelementen (61, 62), die federelastisch miteinander verbunden sind, wobei mindestens einer der Ringelemente (61) ein oder mehrere Haltelemente (64) aufweist, um das Federelement mit einem Rotor (5) zu verspannen und das Federelement dadurch an dem Rotor (5) zu halten.
