Abstract

Strömungsmaschine mit Rotor und Stator in zumindest abschnittsweise axialer Bauart, mit Laufschaufeln am Rotor und gehäusefesten Leitschaufeln, wobei letztere als mindestens ein Leitschaufelkranz mit einem inneren und einem äußeren Deckband angeordnet sind.
Der mindestens eine Leitschaufelkranz ist als selbsttragendes Bauteil mit einer geschlossenen, das Bauteil gegen stülpende Axialverformung versteifenden Verstärkung am inneren Deckband ausgeführt, weist ein segmentiertes äußeres Deckband auf und ist über mindestens drei Deckbandsegmente mittels jeweils radiale Relativbewegungen zulassender Lagereinheiten im Gehäuse positioniert.
Zwischen dem Gehäuse und dem äußeren Deckband des mindestens einen Leitschaufelkranzes ist eine Luftleitschale angeordnet, welche einen Kühlluftstrom längs der Gehäuseinnenseite führt und mit Öffnungen für die gehäusefesten Lagerelemente des mindestens einen Leitschaufelkranzes versehen ist.
