Abstract

Um die Komponenten eines Leitapparates für eine axial durchströmte Turbine sowohl leichtgängig betätigbar zu machen als auch nur geringe Spaltströmungen zuzulassen wird eine Axialströmungsmaschine vorgeschlagen mit einem eine Reihe von verstellbaren Leitschaufeln (30) umfassenden Leitapparat im Strömungskanal (20), der zum einen durch eine innere kugelförmig ausgebildete Nabe (21) und zum anderen durch einen äußeren kugelförmig ausgebildeten Leitschaufelträger (7) begrenzt ist, wobei die Leitschaufeln (30) einerseits in radialen Lagerbohrungen des ringförmigen Leitschaufelträgers (7) drehbar gelagert sind und andererseits das kugelförmig ausgebildete Kopf- und Fußprofil (32, 31) der Leitschaufeln (30) gegen den Leitschaufelträger (7) und die Nabe (21) dichten, bei der die Nabe (21) zumindest im Dichtbereich (23) der inneren Spitzen (31) der Leitschaufeln (30) mit einer nachgiebigen Nabenkontur (9) ausgeführt ist und die Lagerung der Leitschaufeln (31) in Richtung der Leitschaufelachsen (A) ebenfalls nachgiebig ausgestaltet ist.

Figure 00000001
In order to make the components of a diffuser for an axially flowed turbine both easy to operate and to allow only small gap flows, an axial flow machine is proposed with a diffuser in the flow channel (20) comprising a series of adjustable guide vanes (30), which on the one hand has an inner spherical shape formed hub (21) and on the other hand is limited by an outer spherical guide vane carrier (7), the guide vanes (30) on the one hand being rotatably mounted in radial bearing bores of the annular guide vane carrier (7) and on the other hand the spherical head and foot profile (32 , 31) of the guide vanes (30) seal against the guide vane carrier (7) and the hub (21), in which the hub (21) at least in the sealing area (23) of the inner tips (31) of the guide vanes (30) with a flexible hub contour (9) is executed and the storage of the guide vanes (31) in the direction of Guide vane axles (A) is also flexible.
