- 過度の不均衡に起因するデカップリングの場合に、ステータ構造(3)の軸Xに対してロータシャフトを再センタリングするためのロータシャフト(1)のための再センタリング装置であり、前記シャフトが、通常の運転状態においては軸X上に位置し、且つ前記ステータ構造(3)における軸Xのボア内に配置される軸受け支持体(5)によって径方向に支持されており、前記軸受け支持体(5)が、デカップリングの場合に、前記軸受け支持体が軸Xのまわりで軌道周回するのを可能とするために、前記ボアよりも小さい外径を有しており、前記軸受け支持体(5)が、径方向のフューズエレメント(6)によってステータ構造(3)に結合され、前記再センタリング装置は、デカップリング後に軸受け支持体を再センタリングするための手段を備えている、再センタリング装置であって、
軸受け支持体(5)の再センタリング手段が、デカップリング後に移動されるその軌道の方向と反対の方向に、前記軸受け支持体(5)による歳差運動Pでの運動を生じさせるための手段(10)と、軸Xに対する前記軸受け支持体(5)の許容されたクリアランスを低減するための複数の装置(20)とを備え、クリアランスを低減させるための前記装置が、ステータ構造(3)と軸受け支持体(5)からなる2部品の軸(X、11)の周りに一様に配置されており、各部品が、前記2部品のうちの一方に設けられている第1の傾斜面(21)と、前記2部品のうちの他方に設けられている突出部(22)を含み、前記突出部(22)が、通常の運転状態において、前記第1の傾斜面(21)から径方向に空間が空けられており、且つ前記軸受け支持体(5)の歳差運動Pでの運動の間に前記第1の傾斜面に接触し得るということを特徴とする、再センタリング装置。 - 全ての突出部(22)が、第1の傾斜面(21)に同時に接触することが可能であることを特徴とする、請求項1に記載の装置。
- 第1の傾斜面(21)が、円に対する伸開線状の輪郭を有し、2つの隣接する第1の傾斜面が、径方向の肩部(23)によって結合されていることを特徴とする、請求項1または2に記載の装置。
- 第1の傾斜面(21)が、アルキメデスのらせんの輪郭を有することを特徴とする、請求項3に記載の装置。
- 突出部(22)が、ブロックの形態に作られていることを特徴とする、請求項1から4のいずれか一項に記載の装置。
- 突出部(22)が、第2の傾斜面(21)の端部によって形成されており、前記第2の傾斜面が、第1の傾斜面の輪郭と同様の輪郭を有していることを特徴とする、請求項1から4のいずれか一項に記載の装置。
- 第1の傾斜面(21)および突出部(22)が、金属から作られていることを特徴とする、請求項1から6のいずれか一項に記載の装置。
- 突出部(22)が、通常の運転状態で、関連する第1の傾斜面(21)から、デカップリングの間の軸受け支持体(5)の予期される径方向変位(JB)よりも大きな距離だけ、径方向に間隔をあけた位置に配置されることを特徴とする、請求項7に記載の装置。
- 第1の傾斜面(21)が、エラストマから作られており、第2の傾斜面(24)が、金属から作られ、且つ歳差運動Pにおける運動を発生させるために、デカップリング後に、滑動なしに第1の傾斜面を転動し得ることを特徴とする、請求項6に記載の装置。
- 歳差運動(P)における運動を発生するための手段が、ステータ構造(3)に固定されたエラストマリング(10)を備え、前記リング(10)が、軸受け支持体(5)を囲み、且つ軸受け支持体(5)がデカップリング後に前記リング(10)のボア内で滑動することなく転動し得るように、軸受け支持体(5)と永続的な接触状態となることを特徴とする、請求項1から8のいずれか一項に記載の装置。
- エラストマ製の前記リング(10)が、ステータ構造(3)のボア内に配置されることを特徴とする、請求項10に記載の装置。
- 前記リング(10)が、剛性で、可撓性金属支持体(30)によってステータ構造に結合されることを特徴とする、請求項10に記載の装置。
- 3個の第1の傾斜面(21)と3個の突出部(22)を備えることを特徴とする、請求項1から12のいずれか一項に記載の装置。
