Description
図1は、ターボチャージャー用転がり軸受が備え付けられる一般的な自動車用ターボチャージャーの概観を示す図である。図1において、矢印1は、外部からターボチャージャーに流入する空気の流れを表す。回転軸7には、矢印2で示されるエンンジンのシリンダー5から排出された排気ガスにより高速回転するタービン8が図1における右側端部に設けられている。図1における回転軸7の左側端部にはコンプレッサー3が設けられている。矢印2は、シリンダー5から燃焼後に排出される排気ガスの流れを表す。また、ターボチャージャー用転がり軸受70は、回転軸7を回転自在な状態で支持する複列転がり軸受である。図1において、転がり軸受70を支持するハウジングは図示を省略している。
