Claims (6)
- 流体式すべり軸受けの形の軸受(39)に取り付けられたローター(14)を有する回転機械を運転する方法であって、
運転中に該ローター(14)は、実質的に軸方向のみに働くスラスト力にさらされ、前記スラスト力は、液圧媒体および軸受面を介して前記軸受(39)の第1ステップ軸受(43)によって吸収かつ消散され、
前記軸受(39)は、第2ステップ軸受(45)を有する、方法において、
前記スラスト力が働くと、前記第2ステップ軸受(45)が、主スラスト方向に前記第1ステップ軸受(43)に作用する力を少なくとも一時的に同時に生成するステップによって特徴付けられる方法。 - 前記ローター(14)の軸方向振動が発生した後、または発生した際にのみ、前記主スラスト方向に作用する前記力が作動される、請求項1に記載の方法。
- 前記方法が、ターボ機械の形の回転機械の過渡的運転状態の間および/または部分負荷運転の間に実行される、請求項1または2に記載の方法。
- 前記方法が、静的ガスタービン(10)の形のターボ機械において実行される、請求項1〜3のいずれか一項に記載の方法。
- 前記方法が、前記ローター(14)の軸方向変位の前および/またはその最中に実行される、請求項1〜4のいずれか一項に記載の方法。
- 前記第1および第2ステップ軸受が液圧アキシアル軸受の形である請求項1〜5のいずれか一項に記載の方法。
