Abstract
Description
−下流の延在は、軸内の歪エネルギーの分布及びこの結果としてもたらされる吸収エネルギーの調節を可能にする剛性調節レバーを形成する可撓性リンクによって実現されており、この結果、可撓性リンクにより、下流衝撃吸収装置の剛性を制御することが可能であり、且つ、従って、良好に軸内の歪エネルギーを分散させることによって臨界速度の影響を限定することが可能であり、
−追加の衝撃吸収装置の下流におけるオフセットは、半径方向の圧縮によって最大限の衝撃吸収を提供するために、この衝撃吸収装置を軸の変形部内に配置するように、反復的に算出され、従って、噛合部の両側には、最適なトルク伝達を提供する2つの剛性軸受が位置している。
−2つの下流軸受は、共通ケーシング上に取り付けられた可撓性フレームによって連結されており、
−圧縮可能な衝撃吸収装置は、スクイーズ膜から、特に、可撓性フレームによって軸上においてセンタリングされたスクイーズ膜から構成されており、
−追加の下流軸受の転動要素システムは、ボール軸受又はローラー軸受であってよい。
