Abstract

Die Erfindung bezieht sich auf ein Verfahren zur Fixierung für eine Beschaufelung einer Strömungsmaschine. In dem Verfahren werden zuerst die Turbinenschaufeln (31, 32) in die Befestigungsnut (1) eines Rotors (2) oder Stators eingesetzt bis nur noch der Montagezwischenspalt übrigbleibt, in den danach zwei als Schlusshälften (41, 42) ausgebildete Einsatzelemente eingesetzt werden. Darauf wird ein Keil (6) in den Spalt zwischen die Schlusshälften (41, 42) eingesetzt und die Schlusshälften (41, 42) werden mit dem Keil (6) mit einer Verbindungsschweissung (10) verscheisst. Mit dem erfindungsgemässen Verfahren und der erfindungsgemässen Anordnung werden vorteilhaft axiale Kräfte, die den Rotor (2) verbiegen können und so erhöhte Rotorvibrationen hervorrufen, vermieden. Die Erfindung bezieht sich auch auf eine erfindungsgemässe Fixiervorrichtung.
