Description

DEUTSCHESGERMAN

Die Erfindung betrifft eine Einrichtung zur zentrisch wärmebeweglichen Abstützung des Innengehäuses einer Turbine gegenüber dem Außengehäuse bei großem Zwischenraum zwischen Innen- und Außengehäuse.The invention relates to a device for the centrically heat-flexible support of the inner housing a turbine compared to the outer casing with a large gap between the inner and outer casing Outer casing.

Es ist bekannt, diesen Zwischenraum durch radiale Vorsprünge zu überbrücken, die sternstrahlenförmig an das Außengehäuse oder das Innengehäuse angegossen und an denen die Zentrierbolzen oder Zentrierkeile angebracht sind. Diese angegossenen Vorsprünge sind nachteilig, weil sie schwierig zu bearbeiten sind und örtliche Werkstoffanhäufungen bilden, die bei schnellen Temperaturänderungen das Gehäuse leicht unrund werden lassen.It is known that this gap can be bridged by radial projections in the shape of a star Cast onto the outer housing or the inner housing and on which the centering bolts or centering wedges are appropriate. These molded projections are disadvantageous because they are difficult to machine and form local accumulations of material that easily damage the housing in the event of rapid temperature changes get out of round.

Diesen Nachteil vermeidet die Erfindung. Sie besteht darin, daß ein in das Außengehäuse fest eingesetzter Ring mittels Keilführungen das Innengehäuse wärmebeweglich zentriert.The invention avoids this disadvantage. It consists in the fact that a firmly inserted into the outer housing Ring by means of wedge guides centers the inner housing so that it is thermally movable.

Freilich ist eine Turbine bekannt, deren Innengehäuse im Außengehäuse mittels eines Ringes zentriert ist, der ins Außengehäuse eingesetzt ist und mittels Keilen das Innengehäuse trägt. Doch ist dort der Zwischenraum zwischen Außen- und Innengehäuse, den der Ring überbrückt, nur gering. Jene Turbine gibt also nicht die Lehre, angegossene Vorsprünge als Zentriermittel zu vermeiden; sie weist vielmehr solche Vorsprünge an anderer Stelle, nämlich dort, wo das jüngere Ende des konischen Innengehäuses zentriert ist, selbst auf.Of course, a turbine is known whose inner housing is in the outer housing by means of a ring is centered, which is inserted into the outer housing and carries the inner housing by means of wedges. But is there the gap between the outer and inner housing, which the ring bridges, is only small. That turbine So does not give the teaching to avoid cast projections as centering means; rather, it has such Projections elsewhere, namely where the younger end of the conical inner housing centers is, even on.

Die Erfindung sei an Hand eines Ausführungsbeispiels erläutert, das in den Fig. 1 und 2 in einem Querschnitt und einem Längsschnitt dargestellt ist. 1 ist ein ungeteiltes Topfgehäuse, 2 der in der Achsebene unterteilte Leitschaufelträger, dessen Hälften durch Schrauben 3 zusammengehalten sind. Der Unterschied zwischen dem Außendurchmesser des Leitschaufelträgers und dem Innendurchmesser des Gehäuses ist verhältnismäßig groß. Gemäß der Erfindung ist nun in das Gehäuse 1 ein Ring 4 eingesetzt, der durch Bolzen 5 gegen Verdrehung gesichert ist. An den Ring 4 sind in gleichmäßiger Verteilung Erhebungen 6 mit Nuten 7 angearbeitet, während der Wärmebewegliche AbstützungThe invention will be explained using an exemplary embodiment which is shown in FIGS. 1 and 2 in one Cross-section and a longitudinal section is shown. 1 is an undivided cup housing, 2 is the one in the axial plane subdivided guide vane carriers, the halves of which are held together by screws 3. Of the Difference between the outside diameter of the guide vane and the inside diameter of the Housing is relatively large. According to the invention, a ring 4 is now inserted into the housing 1, which is secured against rotation by bolts 5. On the ring 4 elevations are evenly distributed 6 machined with grooves 7, during the heat-movable support

Leitschaufelträger 2 mit entsprechenden Keilflächen 8 versehen ist. Die Nuten 7 sind in axialer Richtung offen. Zum genauen Einpassen der Keilflächen 8 in die Nuten 7 dienen Beilagen 9. Der Ring 4 liegt gegen eine Schulter 10 des Außengehäuses 1 an, während er auf der anderen Seite durch den Gehäusedeckel 11 gehalten ist.Guide vane carrier 2 is provided with corresponding wedge surfaces 8. The grooves 7 are in the axial direction open minded. Inserts 9 are used to precisely fit the wedge surfaces 8 into the grooves 7. The ring 4 is opposite a shoulder 10 of the outer housing 1, while it is held on the other side by the housing cover 11 is.
