Abstract

Bei einer kraft- und formschlüssige Verbindung von rotierenden Bauteilen (1,2), welche im Bereich der Verbindung während der Rotation unterschiedliches Dehnungsverhalten aufweisen, erfolgt der Formschluss über einen gestuften Zentriersitz (3). Der Kraftschluss zwischen den beiden Bauteilen erfolgt mittels axial vorgespannter Elemente. Zumindest eines der Bauteile weist einen Hohlraum (6) im Innern auf, in dem ein Einlagering (7) angeordnet ist, welcher während des Betriebes eine radiale Kaft auf den Zentriersitz (3) ausübt. Der vorgespannte Einlagering (7) liegt nur mit einem Teil seiner axialen Erstreckung an dem mit ihm zusammenwirkenden Bauteil (1) an.
