Abstract
Gasturbine mit einem Rotor, der einen Turbinenrotor (1), eine Welle (11) und einen Verdi chterrotor umfasst, wobei der Turbinenrotor mindestens eine Lauf scheibe (3,4,5) und einen von der oder einer Lauf Scheibe zur Welle führenden Rotorkonus (9) aufweist, wobei das stromabwärtige Ende der Welle in einem Lager (13) mit Lagerkammer (15) drehbar abgestützt ist, wobei der Innenraum (25) der Welle als Strömungskanal • für Lagerkammersperrluft ausgeführt ist, und wobei der den Rotorkonus stromaufwärts umgebende Raum als Strömungsraum für Kühlluft (21) ausgeführt ist. Die Welle weist im Bereich der Rotoranbindung (33) eine Aufweitung (27) auf, an deren stromaufwärtigem Ende Öffnungen (28) für den Eintritt von Kühlluft, und an deren stromabwärtigem Ende Öffnungen für den Austritt von Kühlluft in den Raum (24) zwischen Lagerkammer und Rotorkonus vorhanden sind, wobei eine Wand (31) die Ströme der Kühlluft und der Sperrluft (19) im Welleninneren voneinander trennt.
