Claims (1)
置によって、前記回転を支持した軸受内面側の真円形状
ラント部の内部に、周方向に指向されかつ前記回転軸の
回転方向に向って次第に浅く形成された湾曲底面を有す
る複数の窪み部を周方向に配列させて設けるとともに、
前記各窪み部を連通路によって軸受周囲に連通させたこ
とを特徴とする軸受装置。The bearing device of the rotating shaft, which is lubricated by high-pressure fluid around the bearing, causes a circular runt portion on the inner surface of the bearing that supports the rotation to be directed in the circumferential direction and gradually toward the rotational direction of the rotating shaft. A plurality of depressions each having a shallowly formed curved bottom are arranged in the circumferential direction, and
A bearing device characterized in that each of the recessed portions is communicated with a surrounding area of the bearing through a communication path.
