Claims (1)
材の互いの対向面のうち少なくとも一方の面に円
周方向等間隔を複数本のヘリングボーン形の動圧
発生溝を形成した動圧流体軸受において、前記動
圧発生溝の少なくとも一本が、溝頂部側の軸方向
に対向する溝端部を結ぶ直線が溝内のみを通るよ
うに、他の動圧発生溝より円周方向幅を大きく形
成してなる動圧流体軸受。 A dynamic pressure generating device comprising a shaft and an outer member that moves together with the shaft, and a plurality of herringbone-shaped dynamic pressure generating grooves are formed at equal intervals in the circumferential direction on at least one of the opposing surfaces of the two members. In a hydrodynamic bearing, at least one of the dynamic pressure generating grooves has a circumferential width smaller than other dynamic pressure generating grooves so that a straight line connecting axially opposing groove ends on the groove top side passes only within the groove. A large hydrodynamic bearing.
