Abstract

Die Erfindung betrifft eine Turbomaschine, insbesondere eine Gasturbine, mit einem Stator und einem Rotor, wobei der Rotor Laufschaufeln und der Stator ein Gehäuse und Leitschaufeln aufweist, wobei die rotorseitigen Laufschaufeln mindestens einen Laufschaufelkranz bilden, der an einem radial außenliegenden Ende desselben an eine als Mantelring (10) ausgebildete, radial innenliegende Gehäusewand des Gehäuses angrenzt, von derselben umgeben ist und mit derselben einen Spalt begrenzt, und wobei der Spalt zwischen dem Mantelring (10) des Gehäuses und dem radial außenliegenden Ende des oder jedes Laufschaufelkranzes durch Verformung des Mantelrings (10) einstellbar ist. Erfindungsgemäß ist der Mantelring (10) von einer als Überwurfring ausgebildeten Stelleinrichtung (11) konzentrisch umgeben, wobei sich gegenüberliegende Flächen (12, 13) des Mantelrings (10) und der Stelleinrichtung (11) kegelstumpfförmig konturiert sind, und wobei zwischen dem Mantelring (10) und der Stelleinrichtung (11) in Radialrichtung und in Umfangsrichtung gegenüber der Axialrichtung schräg angestellte Wälzkörper (14) positioniert sind, sodass die Stelleinrichtung (11) gegenüber dem Mantelring (10) unter gleichzeitiger Einstellung des Spalts verdrehbar ist.
