Abstract
【解決手段】鉄道車両の車軸40を回転自在に支持するための鉄道車両車軸用軸受は、軸方向に隣接した一対の内輪22、複列の軌道を持った外輪24,内輪22と外輪24間で転動自在な複列の円すいころ26、保持器28からなる複列円すいころ軸受で構成され、外輪24の両端部にオイルシール30を有し、後蓋32と油切り34により密封している。車軸40の端部に呼び径とピッチが、第一のおねじ部42>第二のおねじ部44となるように形成し、軸方向の締結を第一のおねじ部42に前蓋36を締め付け、第二のおねじ部44に小蓋38を締め付けることにより行って緩み止めをする。車輪旋削時には、ゴムキャップ50を外すだけで、容易に車輪旋削センタを、センタ穴46に挿入することができ、即座に車輪旋削が可能となる。
