摘要: A dynamic pressure bearing apparatus includes a bearing portion; a shaft; a substantially annular bushing; a radial dynamic pressure bearing portion; and a seal gap. A minute horizontal gap extending radially is defined between an upper surface of the bearing portion and a lower surface of the bushing. The seal gap is arranged to be in communication with an exterior space through the horizontal gap.

摘要: A fan includes a motor and an impeller. The motor includes a stationary portion and a rotating portion. The stationary portion includes a stator and a bearing portion. The bearing portion includes a sleeve and a bearing housing. The rotating portion includes a rotor magnet, a shaft, and a thrust plate. A radial gap includes a radial dynamic pressure bearing portion arranged to generate a fluid dynamic pressure acting axially downward on a lubricating oil, while a thrust gap includes a thrust dynamic pressure bearing portion arranged to generate a fluid dynamic pressure acting radially inward on the lubricating oil. A circulation hole extending in an axial direction is defined between the bearing housing and the sleeve. The radial gap is arranged to have a radial width in a range of about 5 μm to about 20 μm.
