Abstract

Der Rotor einer Dampf- oder Gasturbine ist mit Laufschaufeln bestückt, die in mehreren radialen Reihen in dem Rotor (6) gehalten sind und die jeweils aus einem in den Rotor (6) eingebauten Schaufelfuß 1, einem Schaufelblatt (2) und einer Deckplatte (3) bestehen. In den einander gegenüber stehenden Neigungsflächen der Deckplatten (3) einer Reihe von Laufschaufeln ist eine offene Tasche (5) eingebracht. Die Taschen (5) zweier benachbarter Deckplatten (3) bilden zusammen einen im wesentlichen geschlossenen Hohlraum, der sich in radialer Richtung des Rotors (6) erweitert. In jeden Hohlraum ist ein Stift (4) frei beweglich eingelegt, dessen größter Querschnitt kleiner als der größte Querschnitt des Hohlraumes aber größer ist als der kleinste Querschnitt des Hohlraumes.
