Abstract

　保持器に内輪の鍔に軸方向を係止される突出部を設けた円錐ころ軸受において、円錐ころを案内する内輪の鍔に応力集中が生じないように、軸受を小型化して負荷容量を増大させることである。 　内輪２の軌道面２ａの大径側のみに円錐ころ４を案内する鍔６を設け、保持器５の大径側に、内径側へ突出して内輪２の鍔６に軸方向を係止される突出部７を設けて、内輪２の鍔６に、その外径面と外側端面を滑らかな凹曲面で結び、円周方向に連なる切欠き溝６ａを設け、保持器５の突出部７の先端部内側をこの切欠き溝６ａに係止することにより、円錐ころ４を案内する内輪２の鍔６に応力集中が生じないように、円錐ころ軸受１を小型化して負荷容量を増大させることができるようにした。
