摘要： Die Erfindung betrifft einen Rotor (1) einer Turbomaschine. Der Rotor besteht zumindest aus einer Welle (2) und einem Laufrad (4, 5). Der Rotor (1) wird durch Axiallager (6, 6') geführt. Aufgabe der Erfindung ist es, bei einer Überlastung der Axiallager (6, 6') ein Anstreifen der Beschaufelung (13) eines Laufrads (4) an der Gehäusewand (14) der Turbomaschine zu verhindern. Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass der Rotor (1) als zusätzliches axiales Führungselement mindestens einen Druckkamm (10, 10') aufweist. Dabei ist das Spiel (S K , S K ') zwischen den Druckkammflächen (17, 17') und den Anlaufflächen (11,11') größer, als das Spiel (S L , S L ') der Axiallager (6, 6'). Dadurch wird bewirkt, dass im Normalbetrieb die axiale Führung durch die Axiallager (6, 6') bewerkstelligt wird. Erst bei einer Überlastung der Axiallager (6, 6') übernimmt der Druckkamm (10, 10') die axiale Führung.
