Description

Das Patent 724 321 bezieht sich auf einen als Drehkörper gestalteten und in mindestens einer ,",chsebene unterteilten Leitschaufel- oder Dichtungsträger, der mehrere Schaufelkränze oder Dichtungsstufen enthält und mittels gleichfalls als Drehkörper ausgebildeter Haltekörper zusammmengehalten ist. Das Kennzeichen des Hauptpatents besteht darin, daß die im Dampfraum angeordneten Leitschaufelträger und Haltekörper unter Vermittlung von Gehäuseteilen, die im Betrieb dem gleichen Temperaturfluß unterworfen sind wie der Leitschaufelträger, mit dem Gehäusemantel zentrisch wärmebeweglich zusammengebaut sind, so daß der geteilte Leitschaufelträger unter Aufrechterhaltung seiner Drehkörperform seine Abmessungen den Temperaturänderungen zwanglos anpassen kann.The 724,321 patent relates to a rotating body and in at least one ", axial plane subdivided guide vane or seal carrier, which contains several blade rings or sealing stages and by means of likewise is held together as a rotating body formed holding body. The license plate of the main patent consists in the fact that the guide vane carriers arranged in the vapor space and holding body with the intermediary of housing parts which are the same in operation Are subjected to temperature flow like the guide vane carrier with the housing jacket are assembled centrally so that they can move heat, so that the divided guide vane while maintaining its rotating body shape its dimensions with the temperature changes can adjust freely.

Bei den im Hauptpatent angegebenen Bauformen dienen die Haltekörper nicht nur dazu, den geteilten Leitschaufelträger, d. h. seine beiden Schalen, zusammenzuhalten, sondern vermitteln auch den zentrisch wärmebeweglichen Einbau des Leitschaufel-bzw. Dichtungsträgers in den Gehäusemantel der Turbine.In the designs specified in the main patent, the holding bodies are not only used to hold the divided guide vane carrier, d. H. to hold its two shells together, but also convey the centrically heat-flexible installation of the guide vane or. Seal carrier in the casing of the turbine.

Gemäß der vorliegenden Erfindung werden diese beiden Aufgaben, nämlich Einbau und Verspannung der Leitschaufelträgerteile, getrennt, indem der Leitschaufelträger unabhängig von den Haltekörpern unmittelbar wärmebeweglich im Gehäuse gelagert wird und die Haltekörper ihrerseits lediglich die Teile des Leitschaufelträgers zusammenhalten. Dadurch wird ermöglicht, die als Spannringe ausgebildeten Haltekörper zur Lagensicherung der beiden Schalen des Leitschaufelträgers zu verwenden und mit einer Schließstelle auszubilden.According to the present invention, these two objects, viz Installation and bracing of the guide vane support parts, separated by the guide vane support is stored in the housing so that it can be moved directly from the heat irrespective of the holding bodies and the holding bodies in turn only hold the parts of the guide vane carrier together. This makes it possible to use the holding bodies, which are designed as clamping rings, for securing the position of the two shells of the guide vane carrier and with a locking point to train.

In der Zeichnung ist ein Ausführungsbeispiel des Gegenstandes der Erfindung durch Abb. i im Längsschnitt und Abb. 2 im Querschnitt dargestellt.In the drawing is an embodiment of the subject matter of Invention shown by Fig. I in longitudinal section and Fig. 2 in cross section.

Der Leitschaufelträger, der als Drehkörper hergestellt, aber in einer Achsebene unterteilt ist, ist mit a bezeichnet. Der Zusammenhalt der beiden Schalen erfolgt durch. Ringe b, die zum Unterschied von den entsprechenden Haltekörpern des Patents 724 321 mit dem Einbau des Schaufelträgers in den Gehäusemantel nichts zu tun haben. Dieser Einbau erfolgt unmittelbar unter Verrnittlung einer Schulter c und radialer Bolzen d. The guide vane carrier, which is manufactured as a rotating body but is subdivided in an axial plane, is denoted by a. The two shells are held together by. Rings b, which, in contrast to the corresponding holding bodies of patent 724 321, have nothing to do with the installation of the blade carrier in the casing shell. This installation takes place directly with a shoulder c and radial bolt d.

Die Ringe b können dabei als einteilige Drehkörper ausgeführt und warm aufgezogen werden. Sie können aber auch, wie in Abb. 2 ersichtlich, als Spannbänder mit Trennstelle und Spannschrauben ausgebildet werden.The rings b can be designed as a one-piece rotating body and drawn on warm. However, as can be seen in Fig. 2, they can also be designed as tensioning straps with a separation point and tensioning screws.

Diese Halteringe übernehmen außer der Aufgabe des unbeweglichen Zusammenhaltens der beiden Schalen a auch diejenige der Passung der beiden Schalen in axialer Richtung.These retaining rings also take on the task of immovable holding together of the two shells a also that of the fit of the two shells in the axial direction.

Wie beim Patent 724 321 können die einteiligen Ringe oder die Spannbänder in gleicher Weise für Leitschaufel- und Dichtungsträger verwendet werden.As the one-piece rings, or the clamping bands can be used in the same way for vane and seal carrier to the Patent 724,321.
