Abstract

Es wird ein Schloß zum Schließen einer Einfahrstelle einer beidseitig hinterschnittenen Umfangsnut für die Aufnahme von Schaufelfüßen (12) von Laufschaufeln eines Turbinenläufers (1) vorgeschlagen, wobei sich ein Füllstück (5) mit den Schaufelfüßen angepaßter Kontur über ein Paßstück (6) gegen eine Tragflanke (3) im Turbinenläufer abstützt. Ein im Bodenbereich des Schlosses (2) vorgesehener Absatz (4) dient zur axialen Abstützung des Füllstückes (5).
Zweckmäßig ist das Paßstück (6) mit einem Schlitz (7) versehen, in den ein Keil (10) zur Aufspreizung des Paßstückes einpreßbar ist.
