Abstract
(DE)
Beschrieben wird ein Wärmestausegment zum lokalen Abtrennen eines Strömungskanals (K) innerhalb einer Ström ungsrotationsmasch ine, insbesondere Gasturbinenanlage, gegenüber eines den Strömungskanal (K) radial umgebenden Statorgehäuses (2), mit zwei axial gegenüberliegenden Fügekonturen (17, 18), die jeweils in Eingriff mit zwei längs des Strömungskanals (K) axial benachbarten Komponenten (4, 4') bringbar sind. Die Erfindung zeichnet sich dadurch aus, dass eine erste (17) der zwei Fügekonturen eine radial orientierte Ausnehmung (27) mit einer konisch geformten Konturfläche (28) aufweist, an die radialwärts ein Befestigungszapfen (31) mit einer konischen Aussenkontur (34) von Seiten einer an die erste Fügekontur (17) benachbart angrenzenden Komponente (4) kraftbeaufschlagt fügbar ist, und dass die erste Fügekontur (17) einen Kragenabschnitt (23) mit einer radial oberen (24) und unteren (25) Kragenoberflächefläche aufweist, der in eine gegenkonturrierte Aufnahmekontur (26) innerhalb der axial benachbarten Komponente (4) durch eine zwischen dem Befestigungszapfen (31) und der konisch geformten Konturfläche (28) wirkenden Fügekraft fügbar ist.
(EN)
The invention relates to a heat accumulation segment for the local separation of a flow channel (K) inside a turbine engine, especially a gas turbine installation, from a stator housing (2) which radially surrounds the flow channel (K). Said heat accumulation segment comprises two axially opposing joining contours (17, 18) that can be respectively brought into contact with two axially adjacent components (4, 4') along the flow channel (K). The invention is characterised in that a first (17) of the two joining contours has a radially oriented recess (27) having a conically formed contour surface (28) to which a fixing journal (31) having a conical outer contour (34) is radially joined in such a way that it is subjected to force from the sides of a component (4) adjacent to the first joining contour (17), and the first joining contour (17) has a collar section (23) with a radially upper (24) and lower (25) collar surface, that can be inserted into a corresponding receiving contour (26) inside the axially adjacent component (4) by a joining force acting between the fixing journal (31) and the conically formed contour surface (28).
(FR)
L'invention concerne un segment d'accumulation de chaleur servant à séparer localement un canal d'écoulement (K) à l'intérieur d'une turbomachine, en particulier d'un système à turbine à gaz, par rapport à un carter de stator (2) entourant radialement le canal d'écoulement (K), lequel segment comporte deux contours d'assemblage (17, 18) axialement opposés et pouvant être amenés en prise avec deux composants respectifs (4, 4') axialement adjacents le long du canal d'écoulement (K). L'invention se caractérise en ce qu'un (17) des deux contours d'assemblage présente un évidement (27), orienté radialement, avec une surface de contour conique (28), contre laquelle un tourillon de fixation (31), présentant un contour extérieur conique (34), peut venir s'appliquer radialement sous l'action d'une force à partir de côtés d'un composant (4) adjacent au premier contour d'assemblage (17), et ce premier contour d'assemblage (17) comporte une section à rebord (23) présentant une surface de rebord radialement supérieure (24) et inférieure (25), laquelle section peut être insérée dans un contour de réception correspondant (26) à l'intérieur du composant (4) axialement adjacent par application d'une force d'assemblage agissant entre le tourillon de fixation (31) et la surface de contour conique (28).
