Abstract
【解決手段】本発明は回転軸(3)の軸受位置(5)の給油装置に関するものである。本装置は、軸受位置(5)を包囲するリング状オイル・タンク(14)と、2つの逆方向に伸長するスピンドル(10、11)を備えたオイル・ポンプ(8)と、オイル供給配管(20)と、および軸受位置(5)の両側に配置されているオイル戻り配管(24、25、26、27)とから構成されている。
【選択図】 図1
Description
本発明による装置は、軸およびその軸受の姿勢および組込方向とは無関係に、軸受位置の連続給油を可能にする。オイル流れのモニタリングはそれ自身既知の手段により可能である。軸の姿勢とは無関係にオイル流れが途切れることのない給油は、例えばターボ分子ポンプまたは超遠心分離器のような高速回転軸において特に重要である。オイルを充填したまま運搬が可能なので、常に所定の姿勢が維持される必要はない。
