Abstract
Description
第2パッドの円周方向端間は、好ましくは第1パッドの円周方向端よりも広い。
ポンプ・チャンバを横切って(ポンプ・チャンバの前後で)差圧が形成され、カムリングは圧力変動に応答して高圧パッドと低圧パッドとの間で移動可能である。ランドとカムリングとの間の間隙は、ベアリングを通過する流体の流れを選択的に変えて圧力を維持する。これにより、撓みの問題を懸念せずに比較的剛性の高いベアリング装架手段を与えることができる。
本発明のさらに別の利点は、下記の詳細な記載を読みかつ理解したとき当業者にとっては明らかになるであろう。
高圧パッドの幾何学的形状は、流体圧によって発生された力が内部ポンピング要素によって発生された力よりわずかに大きくなるように、決定される。第1高圧パッド102の円周方向範囲、すなわち4時から8時までの範囲は、カムリング70の半径方向厚みによって画定される。第1高圧パッド102の縁102a、102bは、カムリング70の内面72の径寸法を示す水平線の長さ部分よりも外側に外れた位置に配置されることが望ましい(図5参照)。シールおよび高圧溝の側面は、カムスリーブ(ヨーク)の面50a、50bに沿っていて、且つ、ポンピング要素を挟み込むポート板90、92(図3)によって作られる。高圧流体(ジェット燃料)が図6に示すパッド貫通孔120に供給され、カムスリーブ(ヨーク)50とカムリング70との間のインターフェース(接合部分)への流れが貫通オリフィス122(図6においては1つだけが示されている)に制限される。図からわかるように、高圧のオリフィス122は、ベアリング組立体のこの領域における各開口または孔120と連通する。
