Abstract

　円すいころの大端面を受ける鍔部の強度を確保でき、しかも、ころ軸方向長さの延長が可能となって、定格荷重のアップを図ることができる円すいころ軸受を提供する。 　内輪５１と、外輪５２と、内輪５１と外輪５２との間に転動自在に配された複数の円すいころ５３と、円すいころ５３を円周所定間隔に保持する保持器５４とを備え、内輪５１の外径面の大径側にのみ円すいころ５３を案内する鍔部５６を設けた円すいころ軸受である。保持器５４は、大径側環状部５４ａと、小径側環状部５４ｂと、大径側環状部５４ａと小径側環状部５４ｂとを連結する柱部５４ｃとを備える。大径側環状部５４ａに、内径側へ突出して内輪５１の鍔部５６に運転中においては非接触もしくは、引っ掛け部の内径面と鍔部切欠部の外径面のみ接触し、非運転中においては引っ掛かる引っ掛け部６５を設ける。内輪５１の鍔部５６の最大高さ寸法を、円すいころ５３の大端面の直径の３０％以上とした。
