Description
前記保持器をプラスチック製とし、前記ポケットの狭幅側の柱部と小環状部の中央部に、前記保持器と前記内輪との間に流入した潤滑油を前記外輪側へ逃がすための切欠きを設けるとともに、前記保持器の外径面に、前記外輪の内径面に向かって凸状をなし外輪の内径面との間に微小隙間を形成する突起部を円周所定間隔で複数形成し、前記保持器外径面を前記外輪内径面に近接させて、ころ本数を減らさず、あるいは増加させつつ、ころピッチ径を小さくしたことを特徴とするものである。
パラメータRyniは、基準長毎最大高さの平均値、すなわち、粗さ曲線からその平均線の方向に基準長さだけ抜き取り、この抜き取り部分の山頂線と谷底線との間隔を粗さ曲線の縦倍率の方向に測定した値である(ISO 4287:1997)。また、Sk値は粗さ曲線のひずみ度、すなわち、粗さの凹凸分布の非対称性を表す値であり(ISO 4287:1997)、ガウス分布のように対称な分布ではSk値は0に近くなり、凹凸の凸部を削除した場合は負の値、逆に凹部を削除した場合は正の値となる。Sk値のコントロールは、バレル研磨機の回転速度、加工時間、ワーク投入量、研磨チップの種類と大きさ等を選ぶことにより行うことができ、Sk値を−1.6以下とすることにより、無数の微小凹形形状のくぼみに満遍なく潤滑油を保持することができる。
アキシアル荷重:300kgf
回転速度:300〜2000rpm(100rpmピッチ)
潤滑条件:油浴潤滑(潤滑油:75W−90)

- 内輪と、外輪と、内輪と外輪との間に転動自在に配された複数の円錐ころと、円錐ころを円周所定間隔にポケット内で保持する保持器とを備え、保持器が、円錐ころの小端面側で連なる小環状部と、円錐ころの大端面側で連なる大環状部と、これら大小環状部を連結する複数の柱部とからなり、前記隣接する柱部間で、前記ポケットが、円錐ころの小径側を収納する部分が狭幅側、大径側を収納する部分が広幅側となる台形状に形成された円錐ころ軸受において、
前記保持器をプラスチック製とし、前記ポケットの狭幅側の柱部と小環状部の中央部に、前記保持器と前記内輪との間に流入した潤滑油を前記外輪側へ逃がすための切欠きを設けるとともに、前記保持器の外径面に、前記外輪の内径面に向かって凸状をなし外輪の内径面との間に微小隙間を形成する突起部を円周所定間隔で複数形成し、前記保持器外径面を前記外輪内径面に近接させて、ころ本数を減らさず、あるいは増加させつつ、ころピッチ径を小さくした円錐ころ軸受。
