Description
Die Erfindung behandelt eine Sonderaufgabe, die im Zusammenhang mit der Verwendung eines elastischen Zwischenringes geringer Wandstärke zur wärmebeweglichen Abstützung eines Turbinenteiles entsteht. Infolge seiner geringen Wandstärke ist ein solcher Zwischenring nicht in der Lage, größere Kräfte aufzunehmen. Insbesondere ist er empfindlich gegen Beanspruchungen, die dadurch entstehen, daß an einem Schenkel Zugkräfte ausgeübt werden. Die hierbei auftretenden Beänspruchungen sind wesentlich größer als etwa diejenigen, die durch einen auf seine gewölbte Seite ausgeübten überdruck entstehen. Die Maßnahme gemäß der Erfindung besteht darin, daß der elastische Zwischenring an seinem einen Ende einen kräftigen Flansch besitzt, der radial beweglich, aber axial im wesentlichen unbeweglich, etwa durch an sich bekannte Radialbolzen, mit dem abzustützenden Turbinenteil verbunden ist, während das andere Ende des Zwischenringes am abzustützenden Turbinenteil in an sich bekannter Weise dampfdicht befestigt ist.The invention deals with a special task related to the use of an elastic intermediate ring of small wall thickness for heat-flexible Support of a turbine part is created. As a result of its low wall thickness Such an intermediate ring is not able to absorb larger forces. In particular he is sensitive to stresses that arise from being on one leg Tensile forces are exerted. The stresses that arise here are essential larger than roughly those exercised by one on its arched side overpressure arise. The measure according to the invention is that the elastic Intermediate ring has a strong flange at one end, which is radially movable, but axially essentially immovable, for example by radial bolts known per se, is connected to the turbine part to be supported, while the other end of the intermediate ring is attached to the turbine part to be supported in a manner known per se in a vapor-tight manner.
Die der Erfindung zugrunde liegende Aufgabe tritt insbesondere auf, wenn es sich darum handelt, die Leitscheibe einer Turbine wärmebeweglich, aber dichtend gegenüber dem Turbinengehäuse oder einem Einbau des Turbinengehäuses aufzuhängen. Ein Ausführungsbeispiel hierfür ist in der Figur dargestellt, und zwar im Zusammenhang mit einer radial beaufschlagten Turbine; die gleiche Anordntmg kann naturgemäß auch bei der Leitscheibe einer axial beaufschlagten Turbine angewendet werden. Es handelt sich um die Aufgabe, die Leitscheibe i wärmebeweglich, dabei aber dichtend gegenüber dem Turbinengehäuse 2 abzustützen. Zur Abstützung dient in bekannter Weise ein elastischer Zwischenring 3, :der bei q. in die Scheibe i eingesteckt ist. Nach den bisherigen Baugrundsätzen würde der Zwischenring 3 unmittelbar in das Turbinengehäuse 2 eingesetzt worden sein. Ist es jetzt für eine Reparatur erforderlich, die Scheibe i vom Gehäuse .abzuziehen, so müßte der elastische Zwischenring 3 aus seiner Verbindungsstelle mit dem Gehäuse 2 herausgezogen werden. Es würde also ein in Richtung seiner Schenkel wirkender Zug ausgeübt werden müssen, wodurch er sehr hoch beansprucht würde. Eine derartige Beanspruchung zu vermeiden, ist die Aufgabe der Erfindung. Sie wird auf folgendem Wege gelöst: Anstatt den Zwischenring 3 unmittelbar in das Gehäuse 2 einzusetzen, wird er an einen verhältnismäßig kräftigen Flansch 5 angesetzt oder besteht mit ihm, wie es das Beispiel zeigt, aus einem Stück. Der Ring 5 ist gegenüber dem Gehäuse 2 durch einen Dichtungsring 6 abgedichtet und außerdem gegenüber der Scheibe i durch Bolzen 7 abgestützt. Wenn jetzt auf die Scheibe i ein nach rechts gerichteter Zug ausgeübt wird, etwa deshalb, weil die Scheibe vom Gehäuse abgezogen werden soll, so wird jetzt diese Beanspruchung von dem elastischen Zwischenring 3 ferngehalten, denn die nach rechts wirkende Kraft wird jetzt von der Scheibe i auf die Bolzen 7 und von diesen auf den Flansch 5 übertragen. Der elastische Zwischenring 3 unterliegt dabei keinerlei Beanspruchung.The object on which the invention is based occurs in particular when it comes to the idler disk of a turbine, heat-movable, but sealing to hang opposite the turbine housing or an installation of the turbine housing. An exemplary embodiment for this is shown in the figure, specifically in context with a radially acted turbine; the same arrangement can naturally also can be used in the idler pulley of an axially loaded turbine. It deals around the task of making the guide disk i heat-movable, but sealing against it to support the turbine housing 2. An elastic one is used for support in a known manner Intermediate ring 3,: the one at q. is inserted into the disk i. According to the previous According to basic principles, the intermediate ring 3 would be inserted directly into the turbine housing 2 have been. Is it now necessary for a repair to remove the washer i from the housing .to withdraw, the elastic intermediate ring 3 would have to be removed from its connection point can be pulled out with the housing 2. So there would be one in the direction of his thighs effective train must be exerted, which would put it under very high stress. One The object of the invention is to avoid such stress. She will be on solved in the following way: Instead of inserting the intermediate ring 3 directly into the housing 2, it is attached to a relatively strong flange 5 or consists with him, as the example shows, from one piece. The ring 5 is opposite the housing 2 sealed by a sealing ring 6 and also against the disk i through Bolt 7 supported. If now on the disk i a pull directed to the right is exercised, for example because the disc is to be removed from the housing, so this stress is now kept away from the elastic intermediate ring 3, because the force acting to the right is now from the washer i on the bolts 7 and transferred from these to the flange 5. The elastic intermediate ring 3 is subject no stress whatsoever.
