Abstract

Die Erfindung bezieht sich auf eine Turbinendeckbandsegmentbefestigung mit einem Gehäuse 1 und mehreren in dem Gehäuse 1 angeordneten Deckbandsegmenten 2, dadurch gekennzeichnet, dass die einzelnen Deckbandsegmente 2 mit einem Spiel 3 in Umfangsrichtung zwischen den einzelnen Deckbandsegmenten 2 in dem Gehäuse 1 gelagert sind, dass das Spiel 3 bei einer vorgegebenen Temperaturdifferenz zwischen dem Gehäuse 1 und den Deckbandsegmenten 2 auf Null reduziert ist und dass die Deckbandsegmente 2 mittels einer elastisch verformbaren Lagerung an dem Gehäuse 1 gelagert sind.
