Claims (4)
- 圧縮機側部位(1)とタービン側部位を備え、その両部位にそれぞれ複数の個々のロータ部分(6)が設けられ、これらのロータ部分(6)が、ロータ部分(6)の中心部を自由に貫通して導かれた共通の連結棒(4)によって集合結合され、タービン側部位にもっとも近く配置された圧縮機側ロータ部分(6)と圧縮機側部位にもっとも近く配置されたタービン側ロータ部分(6)との間に、連結棒(4)を空間を隔てて取り囲む中空軸(11)が設けられているガスタービンのロータ(2)であって、
この連結棒(4)が、中空軸(11)の軸方向部分域において少なくとも1つの円周方向に巡る横断面星型ばね(10)を介して固定され、この横断面星型ばね(10)がそのすぐ外側のロータ部分に当接支持されていることを特徴とするガスタービンのロータ(2)。 - 中空軸(11)の内部に連結棒(4)に対して同軸的に、1つあるいは複数の冷却空気分離管(12、14)が外側ロータ部分として配置され、連結棒(4)とそのすぐ外側の冷却空気分離管(12)との間に横断面星型ばね(10)が配置されていることを特徴とする請求項1に記載のロータ(2)。
- 各冷却空気分離管(12、14)が、これを円周方向に巡る複数の横断面星型ばね(10)を介して所々で固定されていることを特徴とする請求項2に記載のロータ(2)。
- 請求項1ないし3のいずれか1つに記載のロータ(2)を備えていることを特徴とするガスタービン。
