- 圧縮羽根が取り付けられた軸を駆動することで、圧縮羽根を所定回転数で回転させて冷媒を圧縮するターボ圧縮機に用いられた転がり軸受であって、
ターボ圧縮機の軸を支持しつつ相対回転可能に対向配置された軌道輪と、これら軌道輪の対向面にそれぞれ形成された軌道溝間に転動自在に組み込まれた複数の転動体と、各転動体を1つずつ回転可能に保持する複数のポケットを有する保持器とを具備し、
一方の軌道輪には、その軌道溝の片側に保持器案内面が構成されていると共に、保持器には、一方の軌道輪の保持器案内面に対向する部位に軌道輪案内面が構成されており、
保持器案内面及び軌道輪案内面のいずれか一方又は双方には、軸受内部に供給された潤滑剤を排出する排出部が設けられていることを特徴とする転がり軸受。 - 排出部は、いずれか一方又は双方の保持器案内面及び軌道輪案内面を一部窪ませて形成した凹状溝として構成されており、当該凹状溝は、保持器案内面及び軌道輪案内面を横断する方向に貫通して形成されていることを特徴とする請求項1に記載の転がり軸受。
- 保持器は、合成樹脂材料で形成されていることを特徴とする請求項1又は2に記載の転がり軸受。
