Abstract (en)

The fixture device is for an auxiliary protective shield (220) in a turbo machine. It fixes the shield in a radial and axial installation position and comprises several accommodation components (221,222,223). The accommodation components are arranged in at least three different axial installation positions on the shield and engage in grooves of a shaft or a housing (2) of the turbo machine. The furthest axially outer-lying accommodation components (221,223) in the installation state are arranged in a radial direction (R) free of clearance in the fixture grooves and the accommodation components (222) arranged axially between them have a radial clearance (s) in the fixture groove.

Abstract (de)

Eine Befestigungsvorrichtung für einen Hitzeschutzschild (220) einer Gasturbine wird mit einem mittleren Aufnahmeelement (222) versehen, das in radialer Richtung ein definiertes Einbauspiel (s) mit einer Aufnahmenut aufweist. Im normalen Betreibszustand hat dieses Aufnahmeelement keine Funktion, derart, dass thermische Differenzdehnungen in radialer Richtung zwischen dem Hitzeschutzschild (220) und seinem Gegenstück (2) im Rahmen dieses definierten Spiels unbehindert möglich sind. Erst, wenn die radiale Differenzdehnung das Mass s überschreitet, beginnt das Aufnahmeelement 222 zu tragen. Damit wird die Verformung des Hitzeschutzschildes zu einem relativbewegten Bauteil (LA2) hin begrenzt, und ein exzessives Anstreifen der Bauteile aneinander vermieden. <IMAGE>
