Abstract

Beschrieben wird eine Fixiervorrichtung für eine Beschaufelung einer Strömungsmaschine, bei der längs einer Befestigungsnut (1) eine Anzahl von Schaufeln (31, 32) eingebracht ist und zwischen wenigstens zwei innerhalb der Befestigungsnut (1) benachbart eingebrachter Schaufeln (31, 329 ein Montagezwischenspalt vorgesehen ist, mit zwei als Schlusshälften (41, 42) ausgebildeten Einsatzelementen, die in den Montagezwischenspalt einsetzbar sind und jeweils eine an die Breite des Montagezwischenspaltes angepaßte Breite aufweisen sowie zwischen sich einen Spaltraum (5) einschließen, in den ein Keilelement (43) einsetzbar ist, das derart verkeilbar ist, dass beide Schlusshälften (41, 42) formschlüssig durch das Keilelement (43) innerhalb der Befestigungsnut (1) fixiert sind.
Die Erfindung zeichnet sich dadurch aus, dass das Keilelement (43) zumindest ein Verbindungselement (45) zur Seite einer Schaufel (31, 32) und zumindest eine der beiden an das Keilelement (43) angrenzenden Schaufeln (31, 32) eine zu dem Verbindungselement (45) korrespondierende Gegenkontur (46) vorsieht, sodass das Keilelement (43) und die Schaufel (31, 32) eine Formschlußverbindung miteinander eingehen.
