Abstract
Description
ころ60のクラウニング部72の無次元ドロップ量Daは、次の条件を満たす値である。図3を参照する。ころ60のころ軸方向の中央60bから端面60aまでの距離をLhとする。ころ60の中央60bからころ軸方向にLh×80%の位置を評価位置Peという。このとき、無次元ドロップ量Daは、この評価位置Peにおけるころ60のクラウニング部72のドロップ量をLh×80%で割った値となる。ここでの評価位置Peにおけるドロップ量とは、中間部70の半径と評価位置Peでの半径との差で表される。このようにドロップ量を無次元化したのは、ころ60のころ軸方向の長さによらず、そのクラウニング部72のドロップ量を評価するためである。評価位置をLh×80%の位置としたのは、通常、そこにクラウニング部72が設けられ、そこでのドロップ量が偏心体軸受18のピーリングに影響していると考えられるためである。
