Claims (3)
- 冷却油供給装置から供給される冷却油を転がり軸受(1)の軸方向一端側から回転輪の内輪(2)の前記一端側に吐出してこの吐出された冷却油でもって内輪(2)の冷却を行い、この冷却油が吐出される内輪(2)の一端側の外径面と隙間を持って対向して前記吐出された冷却油の軸受内部への流入を規制するシール部(13)を設けて、前記内輪(2)の一端側に吐出される冷却油の一部を、このシール部(13)の前記隙間から転動体(4)が保持器(5)で保持された軸受内部へ潤滑油として流入させるようにした転がり軸受(1)の潤滑装置において、前記シール部(13)の前記隙間を形成する軸方向内側端を前記保持器(5)の軸方向外側端よりも外側に位置させたことを特徴とする転がり軸受の潤滑装置。
- 前記冷却油が吐出される軸方向一端側の内輪(2)の外径面を、その軌道面側へ拡径するテーパ面(2b)とした請求項1に記載の転がり軸受の潤滑装置。
- 前記冷却油が吐出される軸方向一端側の内輪(2)の端面に周方向へ延びる円周溝(6)を設け、前記冷却油をこの円周溝(6)に向けて吐出するようにした請求項1または2に記載の転がり軸受の潤滑装置。
