Description
Claims (4)
- 互いに径が相違する複列の軌道面を有する外輪と、外輪の各軌道面と対応する複列の軌道面を有する内輪と、両輪の各列の軌道面間に異なるピッチ円径をもって配置される複数の小径側玉および複数の大径側玉とを備えているディファレンシャルギヤ装置の回転軸を回転自在に支持する複列玉軸受において、
内輪外周面に、内輪を取り外す際の工具の引っ掛かり部となる凹所が形成されており、該凹所が弾性変形可能な閉鎖部材によって塞がれた状態でディファレンシャルギヤ装置の潤滑油により複列玉軸受の潤滑がなされ、内輪を取り外す際、閉鎖部材は、弾性変形することで前記工具が嵌め込まれることを特徴とする複列玉軸受。 - 閉鎖部材は、凹所に嵌め入れられて加硫されたゴム部材とされていることを特徴とする請求項1の複列玉軸受。
- 凹所が環状溝とされており、閉鎖部材は、2つ割りの合成樹脂製リング部材とされていることを特徴とする請求項1の複列玉軸受。
- 凹所が環状溝とされており、閉鎖部材は、取外し可能なゴム製リング部材とされていることを特徴とする請求項1の複列玉軸受。
