Description
に軌道溝を有する。なお、図5に示すように、内輪1だけにカウンタボア5を設けてもよい。
イットリア(Y203)およびアルミナ(Al203)、その他、適宜、窒化アルミ(AIN)、酸化チタン(TiO2)を混合したものや、アルミナ(Al203)や炭化けい素(SiC)、ジルコニア(ZrO2)、窒化アルミ(AIN)などを用いたものが挙げられる。
、タービン軸21に対してタービン軸21の段部26および間座27を介して軸方向に位置決めされた状態で中間嵌めにて外嵌されており、外輪2,2は、スリーブ25の内周面段部に対してすきま嵌めにて嵌合されているとともに、軸方向に間座を介在させている。そして、両側の外輪2,2においてカウンタボア9,9の存在する側の肩部が、それぞれタービン羽根車22、コンプレッサ羽根車23の側に配置される。つまり、転がり軸受Aが図4に示す状態で図12のコンプレッサ羽根車23の側に配置され、タービン羽根車22の側では転がり軸受Aが図4に示す状態を左右反対にした状態で配置される。これらの外輪2,2は、コイルバネ28によって間座を介して軸方向で互いに引き離される向きに弾発付勢されている。
