Turbomachine rotor, rotor blade for such a turbomachine rotor, supporting strip for such a rotor blade in the turbomachine rotor and corresponding assembling method
The rotor (1) has a rotor blade (2) provided with a blade base (4). A rotor disk (16) has a groove (17) in which the blade base is engaged such that the blade is held in the groove in a radial direction in a form-fit manner. Pre-tensioning devices (7-14, 19-28) are supported at the rotor disk and at...

| description | The rotor (1) has a rotor blade (2) provided with a blade base (4). A rotor disk (16) has a groove (17) in which the blade base is engaged such that the blade is held in the groove in a radial direction in a form-fit manner. Pre-tensioning devices (7-14, 19-28) are supported at the rotor disk and at the blade base, and exert a pre-tensioning force on the blade base in the radial direction. The pre-tensioning devices are designed such that the pre-tensioning force is adjusted when the rotor is in the assembled state. An independent claim is also included for a method for assembling a turbo machine rotor.
Ein erfindungsgemäßer Turbinenmaschinenrotor weist eine Laufschaufel (2) mit einem Schaufelfuß (4), eine Radscheibe (16) mit einer Nut (17), in die der Schaufelfuß (4) eingreift, so dass die Laufschaufel (2) in der Nut formschlüssig in Radialrichtung gehalten ist, und eine Vorspanneinrichtung (7-14,19-28) auf, die sowohl an der Radscheibe (16) als auch an dem Schaufelfuß (4) abgestützt ist und auf den Schaufelfuß (4) eine Vorspannkraft in Radialrichtung ausübt, wobei die Vorspanneinrichtung (7-14,19-28) derart eingerichtet ist, dass die Vorspannkraft im Zusammenbauzustand des Turbomaschinenrotors einstellbar ist. |
