Abstract
【解決手段】ピニオン軸支持用軸受装置3の内部空間における反ピニオンギヤ2b側の端部をシール13で閉塞する一方で、ピニオンギヤ2b側の端部を開放し、前記内部空間に一方向から潤滑油を流すようにしている。これにより、各玉9列へ潤滑油が不足なく供給される。
【選択図】 図1
Description
ピニオン軸のピニオンギヤをケースの内部に位置させた状態でピニオン軸の胴部を当該軸受装置を介してケースの貫通孔に回転自在に支持させ、ケースの貫通孔の円周方向複数箇所に軸方向に沿う溝を設けるとともに、当該溝によって外輪とケースの貫通孔との嵌め合い面に油通路を形成し、この油通路に当該油孔を連通連結することができる。
