Abstract

Die Erfindung betrifft ein Radscheibenanordnung (1; 14; 26) mit einer Radscheibe (2; 15; 27), mehreren Schaufeleinrichtungen (3; 16; 28), die entlang des Außenumfangs der Radscheibe (2; 15; 27) befestigt sind, und mehreren Dichtblechen (4; 17; 29), die in zwei radial voneinander beabstandeten Ringnuten (5, 6; 18, 19; 30, 31) gehalten sind, wobei die erste Ringnut (5; 18; 30) in der Radscheibe (2; 15; 27) vorgesehen ist und axial auswärts durch einen Ringvorsprung (7; 20; 32) begrenzt wird, und wobei die zweite Ringnut (6; 19; 31) durch eine Vielzahl von benachbart angeordneten Ringnutsegmenten definiert ist, die jeweils in den einzelnen Schaufeleinrichtungen (3; 16; 28) vorgesehen sind, dadurch gekennzeichnet, dass zumindest eine sich axial durch den Ringvorsprung (7; 20; 32) hindurch erstreckende Ausnehmung (8; 21; 33) vorgesehen ist, deren minimale Breite in Umfangsrichtung größer als die Breite der Dichtbleche (4; 17; 29) am Innendurchmesser ist, so dass ein Dichtblech (4; 17; 29) axial durch die Ausnehmung (8; 21; 33) zwischen den Ringnuten (5, 6; 19, 19; 30, 31) eingesetzt und in Umfangsrichtung von diesen geführt bewegt werden kann. Ferner betrifft die Erfindung ein Verfahren zur Montage einer solchen Radscheibenanordnung.
