Description

Für Dampf- oder Gasturbinen mit zylindrischem, in das Gehäuse eingesetztem Leits.chaufelträger ist vorgeschlagen worden, den in Achsebene geteilten, Leitschaufelträger durch einteilig ausgeführte Ringe mit Schließkraft, die warm aufgezogen werden, zusammenzuhalten. Wennsolche Schrumpfringe vorn Leitschaufelträger mehrmals gelöst werden sollen, wird die Paßfläche leicht beschädigt.For steam or gas turbines with a cylindrical housing inserted into the housing Leits.chaufelträger has been proposed, the guide vane split in the axial plane one-piece rings with closing force that are pulled on warm, to stick together. If such shrink rings are loosened several times at the front of the guide vane carrier are to be, the mating surface is easily damaged.

Dieser Nachteil wird erfindungsgemäß dadurch. vermieden, daß zwischen jedem Schrumpfring und dem Leitschaufelträger eine ungeteilte konische Buchse vorgesehen ist.According to the invention, this disadvantage is thereby eliminated. avoided that between an undivided conical bushing is provided for each shrink ring and the guide vane carrier is.

Die Buchse hat einen solchen Innendurchmesser, daß sie sich leicht auf den Leitschaufelträger schieben läßt. Sie hat solche Wandstärke, daß sie sich elastisch vom Schrumpfring auf den. LeitscbaufelträgeT pressen läßt; wenn. der Schrumpfring von ihr abgezogen worden ist, so dehnt sie sich wieder aus, und kommt so vom Leitschaufelträger frei, und da sie konisch ist, läßt sich der Schrumpfring bei geringer Erwärmung leicht von ihr und dem Leitschaufelträger abziehen; und schließlich hat sie, da sie ungeteilt ist, von den bekannten, geschlitzten Kegelbuchsen, wie sie z. B. bei Turbinenwellen verwendet werden, den Vorzug, dampfdicht zu sein.The bushing has an inner diameter such that it can be easily moved can be pushed onto the guide vane carrier. It has such a wall thickness that it is elastic from the shrink ring to the. LeitscbaufelordersT can be pressed; if. the shrink ring has been withdrawn from it, it expands again and comes off the guide vane carrier free, and since it is conical, the shrink ring can be removed with little heating easily pull it off of it and the guide vane carrier; and finally she has, there it is undivided by the well-known, slotted tapered sockets, as z. B. at Turbine shafts are used, the privilege of being vapor-tight.

Der Gegenstand der Erfindung ist in den Fig: i und 2 der Zeichnung in zwei Ausführungsbeispielen veranschaulicht.The object of the invention is shown in FIGS. 1 and 2 of the drawing illustrated in two exemplary embodiments.

Hierin bezeichnet i ein Turbinengehäuse und 2 den in dasselbe eingesetzten zylindrischen, längs geteilten Leits.chaufelträger. Die Leitschaufelträgerh.älften werden durch Schrumpfringe 3, 4, 5 zusammengehalten, von, denen der dem Dampfeintritt am nächsten liegende Schrumpfring 3 gleichzeitig zur axialen und radialen Fixierung des Leitschaufelträgers.2 dient.Herein i denotes a turbine housing and 2 denotes the one inserted in the same cylindrical, longitudinally divided guide vane carrier. Halve the guide vane carrier are held together by shrink rings 3, 4, 5, of which the steam inlet the closest shrink ring 3 at the same time for axial and radial fixation of the guide vane carrier.2 is used.

Die Schrumpfringe 3, 4, 5 sind wegen der sich damit ergebenden Vorteile ähnlich wie bei den Turbinenlaufrädern auf ungeteilte konische Buchsen 6 gesetzt.The shrink rings 3, 4, 5 are because of the resulting advantages Set on undivided conical bushings 6, similar to the turbine runners.

Bei großem Gesamtdruckgefälle der Turbine sollen nasch Fig. i die Schrumpfringe 4 und 5 oder deren. mehrere mit Dichtungsringen 7 versehen werden, um den Raum zwischen Leitischaufelträgeründ Gehäuse in mehrere Ringräume zu unterteilen.In the case of a large total pressure gradient in the turbine, FIG Shrink rings 4 and 5 or their. several are provided with sealing rings 7, in order to subdivide the space between the guide vane carrier and the housing into several annular spaces.

Um die Druck- und Temperaturunterschiede zwischen der Außen- und Innenseite des Leitschaufelträgers, herabzusetzen, sind die Ringräume durch Bohrungen 8 mit dem inneren Dampfraum des Trägers.: verbunden;.About the pressure and temperature differences between the outside and the inside of the guide vane carrier, the annular spaces are through holes 8 with the inner vapor space of the wearer .: connected ;.

Der dem Dampfeintritt anliegende Schrumpfring 3 dient gleichzeitig zur axialen und radialen Fixierung des Leitschaufelträgers 2. Dieser Schrumpfring 3 ist mit einer Ausdehnung g versehen, in die eine Ringwulst fo des Gehäuses eingreift. Zu beiden Seiten der Ringwulst fo sind Dichtungsscheiben i i vorgesehen. Der auf den Leitschaufelträger wirkende Differenzdruck gewährleistet eine gute Abdichtung des Schrumpfringes 3 und durch Einwirkung auf dessen zugehörige konische Buchse 6 die Beibehaltung einer festen Verbindung zwischen Leitschaufelträger 2 und diesem Schrumpfring. Der Differenzdruck zwischen den einzelnen Ringkammern ist bestrebt, auch die Schrumpfringe 4 und 5, welche nur zum Zusammenhalten der beiden Hälften des Leitschaufelträgers 2 dienen, durch die entsprechende Neigung der konischen Buchse 6 auf diese zu treiben, so, daß sie weder durch die Dampfdruckdifferem;z noch durch Erschütterungen gelöst werden können. -Bei kleinem Gesamtdruckgefälle kann nach Fig. 2 der den Leitschaufelträger umgebende Raum mit dem Abdampf- bzw. Gegendruckraum verbunden werden.The shrink ring 3 resting against the steam inlet serves at the same time for the axial and radial fixation of the guide vane carrier 2. This shrink ring 3 is provided with an extension g into which an annular bead fo of the housing engages. Sealing washers i i are provided on both sides of the annular bead fo. The on The differential pressure acting on the guide vane carrier ensures a good seal of the shrink ring 3 and by acting on its associated conical socket 6 the retention of a fixed connection between the guide vane carrier 2 and the latter Shrink ring. The differential pressure between the individual annular chambers strives to also the shrink rings 4 and 5, which are only used to hold the two halves together of the guide vane carrier 2 are used by the corresponding inclination of the conical Bush 6 to drive them so that they are neither through the vapor pressure differential; can still be resolved by shocks. -With a small total pressure drop According to Fig. 2, the space surrounding the guide vane carrier with the exhaust steam or Back pressure chamber are connected.
