Description

TECHNISCHES GEBIETTECHNICAL AREA

Die vorliegende Erfindung bezieht sich auf das Gebiet der Turbomaschinen. Sie betrifft eine Abstützung für eine Turbine gemäss dem Oberbegriff des Anspruchs 1.The present invention relates to the field of turbomachinery. It relates to a support for a turbine according to the preamble of claim 1.

STAND DER TECHNIKSTATE OF THE ART

Bei mit thermischen Prozessen arbeitenden Turbomaschinen, wie z.B. Gasturbinen, treten beim Hochfahren am Gehäuse thermische Dehnungen auf, die durch spezielle Abstützungen des Aussengehäuses abgefangen werden (siehe z.B. die DE-U1-78 14 269 oder die EP-A1-0 785 389 oder die US-A-5,542,642 ).In turbomachinery working with thermal processes, such as gas turbines, occur during startup on the housing thermal expansions, which are intercepted by special supports of the outer housing (see, eg, the DE-U1-78 14 269 or the EP-A1-0 785 389 or the US-A-5,542,642 ).

Eine mögliche Konfiguration einer derartig abgestützten Turbomaschine bzw. Turbine ist in Fig. 1 wiedergegeben. Die in Fig. 1 gezeigte Turbine 10 weist ein Aussengehäuse 18 auf, dass entlang einer durch die Maschinenachse 17 gehenden horizontalen Trennebene in ein Oberteil 11 und ein Unterteil 12 unterteilt ist. Oberteil 11 und Unterteil 12 sind in der Trennebene über einen Horizontalflansch 13 miteinander dichtend verbunden bzw. verschraubt. Am Aussengehäuse 18 entlang sind verteilt mehrere vertikale Stützen 14, 15 und 16 angeordnet, die mit dem oberen Ende am Aussengehäuse 18 angreifen und sich mit dem unteren Ende an einen (nicht dargestellten) Boden oder Fundament abstützen.One possible configuration of such a supported turbomachine or turbine is in Fig. 1 played. In the Fig. 1 shown turbine 10 has an outer housing 18 that is divided along a going through the machine axis 17 horizontal parting plane into an upper part 11 and a lower part 12. Upper part 11 and lower part 12 are sealingly connected or screwed together in the parting plane via a horizontal flange 13. On the outer housing 18 along a plurality of vertical supports 14, 15 and 16 are arranged, which engage with the upper end of the outer housing 18 and are supported by the lower end of a (not shown) floor or foundation.

Die Stützen 14, 15 und 16 können dabei entweder ganz oder teilweise an einem separaten Anguss am Aussengehäuse 18 angreifen, was zur Folge hat, dass die auf das Gehäuse einwirkenden Kräfte und Momente durch den grösseren Hebelarm verstärkt werden. Darüber hinaus kann ein separater Anguss unter Umständen zu unerwünschten grösseren Transportabmessungen führen.The supports 14, 15 and 16 can either completely or partially attack on a separate sprue on the outer housing 18, with the result that the forces acting on the housing and moments are amplified by the larger lever arm. In addition, a separate sprue can possibly lead to undesirable larger transport dimensions.

Um dies zu vermeiden, können die Stützen 14, 15, 16 möglichst nahe an die neutrale Faser des Gehäuses herangezogen werden, wo sich die Flanschverschraubung befindet. Dies führt jedoch dazu, dass aus Platzgründen an der Stelle, wo die jeweilige Stütze ansetzt, eine Schraube der Flanschverschraubung weggelassen werden muss. Dies kann zu Problemen bei der Dichtheit der Aussengehäuse führen.To avoid this, the supports 14, 15, 16 can be used as close as possible to the neutral fiber of the housing, where the Flanschverschraubung is located. However, this leads to the fact that for reasons of space at the point where the respective support attaches, a screw of Flanschverschraubung must be omitted. This can lead to problems with the tightness of the outer housing.

Zwei Varianten einer solchen vorbekannten Abstützung sind in den Fig. 2 und 3 dargestellt: Bei der Variante gemäss Fig. 2 ist das mit einem Aussengewinde 23 versehene obere Ende einer Stütze 19 durch ein Durchgangsloch 24 im unteren Flansch 13b des Horizontalflansches 13 hindurchgesteckt und mit dem Unteren Flansch 13b verschraubt. Dazu dienen eine auf die Stütze 19 aufgeschraubte untere Befestigungsmutter 21 und obere Befestigungsmutter 20. Damit die obere Befestigungsmutter 20 auf die Stütze 19 aufgeschraubt werden kann, ist im oberen Flansch 13a eine entsprechende Öffnung vorgesehen. Eine Verschraubung der beiden Flansche 13a und 13b ist an dieser Stelle nicht möglich. Dies gilt auch bei der Variante gemäss Fig. 3, bei welcher die Stütze 19 mit ihrem Aussengewinde 23 in eine entsprechende Gewindebohrung 25 im unteren Flansch 13b eingeschraubt und mit einer Kontermutter 22 gekontert ist.Two variants of such prior art support are in the FIGS. 2 and 3 shown: In the variant according to Fig. 2 is provided with an external thread 23 upper end of a support 19 inserted through a through hole 24 in the lower flange 13b of the horizontal flange 13 and screwed to the lower flange 13b. Serve with a screwed onto the support 19 lower mounting nut 21 and upper mounting nut 20. Thus, the upper mounting nut 20 can be screwed onto the support 19, a corresponding opening is provided in the upper flange 13a. A Screwing the two flanges 13a and 13b is not possible at this point. This also applies to the variant according to Fig. 3 in which the support 19 is screwed with its external thread 23 into a corresponding threaded bore 25 in the lower flange 13b and countered with a lock nut 22.

DARSTELLUNG DER ERFINDUNGPRESENTATION OF THE INVENTION

Es ist eine Aufgabe der Erfindung, eine Abstützung für eine Turbine mit geteiltem Aussengehäuse anzugeben, welche die Nachteile der bisherigen Abstützungen vermeidet und sich insbesondere durch eine optimale Platzierung der Abstützung ohne Einbussen an der Dichtigkeit der Flanschverbindung auszeichnet.It is an object of the invention to provide a support for a turbine with split outer housing, which avoids the disadvantages of the previous supports and is characterized in particular by an optimal placement of the support without sacrificing the tightness of the flange connection.

Die Aufgabe wird durch die Gesamtheit der Merkmale des Anspruchs 1 gelöst. Wesentlich für die erfindungsgemässe Lösung ist, dass eine oder mehrere der Stützen mit dem oberen Ende am Horizontalflansch angreifen und Teil der Horizontalflanschverschraubung sind. Hierdurch kann die Abstützung in eine mechanisch optimale Position verschoben werden, ohne dass an der dortigen Position auf eine dichtende Verschraubung verzichtet werden muss.The object is solved by the entirety of the features of claim 1. Essential for the solution according to the invention is that one or more of the supports engage the upper end on the horizontal flange and are part of the Horizontalflanschverschraubung. In this way, the support can be moved to a mechanically optimal position, without having to do without a sealing screwing at the local position.

Eine Ausgestaltung der Erfindung ist dadurch gekennzeichnet, dass der Horizontalflansch einen oberen Flansch und einen unteren Flansch umfasst, die miteinander verschraubt sind, dass die als Teil der Horizontalverschraubung eingesetzten Stützen jeweils mit ihrem oberen Ende im unteren Flansch derart fixiert sind, dass sie von der Oberseite des unteren Flansches her zugänglich sind, und dass zur Verschraubung der Flansche jeweils eine Flanschschraube durch ein Durchgangsloch im oberen Flansch in die im unteren Flansch fixierte Stütze einschraubbar ist.An embodiment of the invention is characterized in that the horizontal flange comprises an upper flange and a lower flange which are screwed together that the supports used as part of the horizontal screw are each fixed with its upper end in the lower flange such that they from the top the lower flange forth are accessible, and that for screwing the flanges each have a flange through a through hole in the upper flange in the fixed in the lower flange support is screwed.

Insbesondere sind die als Teil der Horizontalverschraubung eingesetzten Stützen zur Fixierung im unteren Flansch jeweils in den unteren Flansch einschraubbar. Vorzugsweise sind die Stützen dabei zur Fixierung im unteren Flansch derart bis zu einem Anschlag in den unteren Flansch einschraubbar, dass zwischen der oberen Stirnfläche der Stütze und der Unterseite des oberen Flansches ein ausreichender Zwischenraum frei bleibt.In particular, the supports used as part of the horizontal screw can be screwed into the lower flange for fixing in the lower flange. Preferably, the supports are for fixing in the lower flange so until screwed to a stop in the lower flange, that between the upper end face of the support and the underside of the upper flange, a sufficient gap remains free.

Eine andere Ausgestaltung der Erfindung zeichnet sich dadurch aus, dass die als Teil der Horizontalverschraubung eingesetzten Stützen als zylindrische Stäbe ausgebildet sind und zur Aufnahme der Flanschschrauben am oberen Ende jeweils ein von der Stirnseite her eingebrachtes, konzentrisches Gewindeloch aufweisen.Another embodiment of the invention is characterized in that the supports used as part of the Horizontalverschraubung are formed as cylindrical rods and for receiving the flange screws at the upper end each have a introduced from the front side, concentric threaded hole.

Dabei ist es mechanisch von Vorteil, wenn die als Teil der Horizontalverschraubung eingesetzten Stützen mit ihren Stirnflächen im wesentlichen bündig an die Oberseite des unteren Flansches anschliessen.It is mechanically advantageous if the supports used as part of the horizontal screw connect with their end faces substantially flush with the top of the lower flange.

WEGE ZUR AUSFÜHRUNG DER ERFINDUNGWAYS FOR CARRYING OUT THE INVENTION

In Fig. 4 ist in einem vergrösserten Ausschnitt und in einer zu Fig. 2 und 3 vergleichbaren Darstellung ein Ausführungsbeispiel einer Abstützung gemäss der Erfindung mit kombinierter Abstützung und Flanschverschraubung wiedergegeben. Die sich am Boden bzw. einem Fundament abstützende Stütze 31 ist mit einem am oberen Ende angebrachten Gewindeabschnitt 28 von unten soweit in den unteren Flansch 13b eingeschraubt, dass die Stirnfläche der Stütze 31 mit der Oberseite des unteren Flansches 13b annähernd bündig abschliesst. Dazu ist im unteren Flansch 13b ein Durchgangsloch 30 vorgesehen, dass in der oberen Hälfte ein entsprechendes Innengewinde aufweist.In Fig. 4 is in an enlarged section and in one too FIGS. 2 and 3 comparable representation of an embodiment of a support according to the invention with combined support and Flanschverschraubung reproduced. The at the bottom or a foundation supporting support 31 is screwed with a threaded portion attached to the upper end 28 from below so far into the lower flange 13b that the end face of the support 31 with the top of the lower flange 13b approximately flush concludes. For this purpose, a through hole 30 is provided in the lower flange 13b that has a corresponding internal thread in the upper half.

Konzentrisch zu dem Durchgangsloch 30 im unteren Flansch 13b ist im oberen Flansch 13a ein Durchgangsloch 27 angeordnet, durch das eine Flanschschraube 26 hindurchgesteckt werden kann. Die Länge der Flanschschraube 26 ist so gewählt, dass sie nach unten aus dem oberen Flansch 13a beträchtlich herausragt, jedoch innerhalb des unteren Flansches 13b endet. Die Flanschschraube 26 stützt sich mit ihrem Schraubenkopf an der Oberseite des oberen Flansches 13a ab und ist mit dem aus dem oberen Flansch 13a nach unten herausragenden Teil in ein dafür vorgesehenes (konzentrisches) Gewindeloch in der Stütze 31 eingeschraubt. Da die Stütze 31 ihrerseits in den unteren Flansch 13b eingeschraubt ist, können durch Anziehen der Flanschschraube 26 die beiden Flansche 13a und 13b unmittelbar im Bereich der Stütze 31 dichtend gegeneinander gedrückt werden.Concentric with the through hole 30 in the lower flange 13b, a through hole 27 is disposed in the upper flange 13a, through which a flange screw 26 can be inserted. The length of the flange screw 26 is selected so that it protrudes downwardly from the upper flange 13a considerably, but ends within the lower flange 13b. The flange screw 26 is supported with its screw head at the top of the upper flange 13 a and is screwed with the projecting from the upper flange 13 a downwardly projecting part in a designated (concentric) threaded hole in the support 31. Since the support 31 in turn is screwed into the lower flange 13b, by tightening the flange screw 26, the two flanges 13a and 13b can be pressed sealingly against each other directly in the region of the support 31.

Auf diese Weise lassen sich die Angriffspunkte der Stützen am Horizontalflansch 13 des Aussengehäuses optimal platzieren, ohne dass auf eine Flanschverschraubung an diesen Punkten verzichtet werden muss. Desgleichen werden keine zusätzlichen Angüsse benötigt.In this way, the points of application of the supports can be optimally placed on the horizontal flange 13 of the outer housing, without causing a Flange screw connection must be omitted at these points. Likewise, no additional sprues are needed.

Grundsätzlich ist es aber auch denkbar, den Gewindeabschnitt 28 an der Stütze 31 wegzulassen und stattdessen an der Stütze 31 und am Durchgangsloch 30 korrespondierende Abstufungen im Aussen- bzw. Innendurchmesser vorzusehen, so dass sich die in das Durchgangsloch 30 gesteckte Stütze 31 am unteren Flansch 13b abstützen kann.In principle, however, it is also conceivable to omit the threaded portion 28 on the support 31 and instead to provide corresponding gradations in the outer or inner diameter on the support 31 and the through-hole 30 so that the support 31 inserted into the through-hole 30 on the lower flange 13b can support.

Besonders günstig ist es, die Stütze 31 mit dem Gewindeabschnitt 28 derart bis zu einem Anschlag 32 in den unteren Flansch 13b einzuschrauben, dass zwischen der oberen Stirnfläche der Stütze 31 und der Unterseite des oberen Flansches 13a ein ausreichender Zwischenraum frei bleibt, so dass die Stütze 31 keine direkten Kräfte vom oberen Flansch 13a aufnehmen muss.It is particularly advantageous to screw the support 31 with the threaded portion 28 as far as a stop 32 in the lower flange 13b, that between the upper end face of the support 31 and the underside of the upper flange 13a a sufficient gap remains free, so that the support 31 does not have to absorb direct forces from the upper flange 13a.
