Description
この発明の転がり軸受装置は、工作機械、風車、鉄道に使用することができる。
図1から図3に示す実施形態の転がり軸受装置10は、転がり軸受11、その軸方向の一端部に突き当てられた間座12及び間座12に組み込まれた給油ユニット13により構成され、回転軸14とハウジング15の間に組み込んで使用に供される。転がり軸受11の他端部にも他の間座16が突き当てられ、両方の間座12、16により転がり軸受11の軸方向の位置決めが行われる。この実施形態の回転軸14は水平に設置されている。
振動波は、図10のように、振動波伝達媒体74を挟み、振動波発生装置70と対向する位置に設けられた振動波検出器77により検出される。
