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.

Figure 00000001
In the case of a non-positive and positive connection of rotating components (1, 2) which have different expansion behavior in the area of the connection during rotation, the positive connection takes place via a stepped centering seat (3). The frictional connection between the two components takes place by means of axially prestressed elements. At least one of the components has a cavity (6) inside, in which an insert ring (7) is arranged, which exerts a radial force on the centering seat (3) during operation. The pretensioned insert ring (7) lies only with a part of its axial extent on the component (1) interacting with it.
