Description
図1は、本発明の実施の形態に係る円すいころ軸受1の断面図である。図1は、円すいころ軸受1の中心軸線L1を通る断面図である。なお、本明細書において、単に「軸方向」というときは、中心軸線L1の延びる方向を意味することとする。
図3に示すように、円すいころ軸受1の下部において、外輪10と潤滑油保持部材50との間に形成される空間には、潤滑油Jが貯留される。つまり、潤滑油Jは、円すいころ軸受1の下部にとどまることとなる。潤滑油Jの液面の高さは、弾性体リップ70の径方向内側の端部のうち、円すいころ軸受1の最下部に位置する部分と略同じ高さとなっている。言い換えると、潤滑油Jの液面の高さは、弾性体リップ70のうち、円すいころ軸受1の最下部に位置する部分の上端と略同じ高さである。
円すいころ軸受1は、例えば、自動車の差動装置などに組み付けられ、図示しないハウジングの内部に配置される。
図5は、変形例1に係る円すいころ軸受1Aの一部を拡大した断面図である。図5に示すように、円すいころ軸受1Aは、円すいころ軸受1の内輪20に代えて内輪20Aを備える点を除き、円すいころ軸受1と同じ構成である。
図6は、変形例2に係る円すいころ軸受1Bの一部を拡大した断面図である。図6に示すように、円すいころ軸受1Bは、円すいころ軸受1の内輪20に代えて内輪20Bを備える点を除き、円すいころ軸受1と同じ構成である。
図7は、変形例3に係る円すいころ軸受1Cの一部を拡大した断面図である。図7に示すように、円すいころ軸受1Cは、円すいころ軸受1の内輪20に代えて内輪20Cを備える点を除き、円すいころ軸受1と同じ構成である。
円すいころ軸受1において、傾斜面232の軸方向他方側の端部232bが、径方向から見て、保持器40と重ならない位置に配置されている例を説明したが、これに限られない。円すいころ軸受1において、傾斜面232の軸方向他方側の端部232bが、径方向から見て、保持器40と重なる位置に配置されていてもよい。この場合であっても、内輪20の正面20aに付着した潤滑油Jを効率的に回収することができる。
図8は、変形例5に係るリング60Aの斜視図である。潤滑油保持部材50は、図4に示すリング60に代えて、図8に示すリング60Aを備えてもよい。
また、円すいころ軸受1において、リング本体61の内周面に凹凸が形成されていなくてもよい。この場合であっても、内輪20の正面20aに付着した潤滑油Jを、円すいころ軸受1の下部における外輪10と潤滑油保持部材50との間の空間に効率よく回収することができる。
