Description
また、ころ径をDw、ころ本数をZ、円周方向すきまをSとしたとき、0.001×Dw×Z≦S≦0.01×Dw×Zの関係が成立するような構成を採用することにより、軸受の運転中の間座やころの熱膨張に伴う円周方向すきまの消滅を回避しつつ、間座の挙動を安定させることができ、振動を抑えることができる。
あり、図5に実施例の構成を、図6に比較例の構成を示す。なお、両者は間座のころ転動面と向き合う面の形状が異なるだけで、その他は同一のものである。

Claims (1)
- 外輪と、内輪と、複数のころと、隣り合うころ間に介在させた間座とを有し、間座のころ転動面と向き合う面がころのピッチ円を跨いで延在する凹形状であり、かつ、間座がいずれかの軌道輪と向き合う拡張部を有し、ころ径をDw、ころ本数をZ、円周方向すきまをSとしたとき、0.001×Dw×Z≦S≦0.01×Dw×Zの関係が成立し、前記軌道輪のつば外径面またはつば内径面の直径をd1、前記拡張部と前記軌道輪のつば外径面またはつば内径面との間のすきまをSrとしたとき、0.005×Dw<Sr<0.1×d1 0.4 の関係に設定することにより、隣り合うころで間座を挟み込んだとき、間座の前記拡張部と前記軌道輪との間にすきまがあり、間座をころ案内としたころ軸受。
