Title
(DE) Radscheibenanordnung eines Rotors und Verfahren zur Montage einer Radscheibenanordnung eines Rotors
(EN) Rotor disc assembly and method for mounting a rotor disc assembly
(FR) Agencement de disque de rotor et procédé de montage d'un agencement de disque de rotor
Abstract
(DE)
Die Erfindung betrifft eine Radscheibenanordnung (1) mit einer Radscheibe (2), mehreren Schaufeleinrichtungen (3), die entlang des Außenumfangs der Radscheibe (2) befestigt sind, und mehreren Dichtblechen (5), die in zwei radial voneinander beabstandeten Ringnuten (6, 7) gehalten sind, wobei die erste Ringnut (6) in der Radscheibe (2) vorgesehen ist und axial auswärts durch einen durchgehenden Ringvorsprung (8) begrenzt wird, und wobei die zweite Ringnut (7) durch eine Vielzahl von benachbart angeordneten Ringnutsegmenten definiert ist, die jeweils in den einzelnen Schaufeleinrichtungen (3) vorgesehen sind, dadurch gekennzeichnet, dass die erste Ringnut (6) zumindest eine einen Dichtblechmontagebereich definierende Vertiefung (13; 20) aufweist, deren Länge in Umfangsrichtung größer ist als die Breite der Dichtbleche (5) am Innendurchmesser.
