Description
Claims (5)
- 軸のための少なくとも1つの磁気ベアリングを備えた蒸気タービンであって、磁気ベアリングの領域に薄板積層体を被せ嵌めてある形式のものにおいて、磁気ベアリング(6)の領域に、軸の軸線方向に延びる冷却空気用の冷却空気通路(9,25,26)を設けてあり、該冷却空気通路は、磁気ベアリングの、翼に向けられた側で、半径方向に延びる冷却空気供給部を含む冷却空気供給装置(8)と接続されていて、支承ケーシング内の軸端部の自由な端部に通じていることを特徴とする蒸気タービン。
- 軸は、薄板積層体(7)を被せ嵌めてある領域に、軸線方向に延びる溝(9)を有しており、該溝は、軸に接触する前記薄板積層体と一緒に冷却通路を画成している請求項1に記載の蒸気タービン。
- 磁気ベアリングの領域で軸にブッシュ(22)を被せ嵌めてあり、該ブッシュは薄板積層体(23)を支持しており、前記ブッシュは該ブッシュの内周面に溝(25)を有しており、該溝は軸の表面と一緒に冷却通路を画成している請求項1に記載の蒸気タービン。
- 磁気ベアリングの領域で軸にブッシュ(22)を被せ嵌めてあり、該ブッシュは薄板積層体(23)を支持しており、前記ブッシュ内に孔(26)を設けてあり、該孔は空気通路を形成している請求項1に記載の蒸気タービン。
- 前記蒸気タービンの軸は、翼を支持する中間部分と該中間部分にねじ結合された2つの軸端部から三部構造で形成されており、冷却空気供給装置から複数の冷却通路を分岐させてあり、該冷却通路は、前記ねじ結合された軸端部の外周部の領域に設けられた半径方向の孔及び軸方向の孔を介して、前記ねじ結合された軸端部の、前記軸の前記中間部分に隣接する端部に通じており、前記中間部分の軸の端部と前記ねじ結合された軸端部との間に室を画成してあり、該室は、前記ねじ結合された軸端部の中央に設けられた軸線方向の孔を介して、該軸端部の自由な端部に通じている、請求項1から4までのいずれか1項に記載の蒸気タービン。
