Description
ベントは一種の逆止弁の作用をし、一方向への通気を許容し、その反対方向への通気を阻止する。
図1に複列円すいころ軸受を用いた鉄道車両車軸用軸受の縦断面を示す。複列円すいころ軸受は、間座を介して軸方向に隣接した一対の内輪42、複列の軌道をもった複列外輪44、内輪42の軌道と外輪44の軌道との間に転動自在に介在する複列の転動体(ここでは円すいころ)46、各列の転動体46を円周方向で所定間隔に保持する一対の保持器48を主要な構成要素とし、外輪44の両端部にオイルシールを含む密封装置50A,50Bが装着してあり、軸受内部に封入したグリースの洩れや、外部から異物が侵入するのを防止している。
