FLUID BEARING

摘要

A fluid bearing for rotatably supporting a rotaty shaft. A plurality of pressure generating zones are defined on a bearing surface of a bearing member in a circumferential direction. Each of the pressure generating zones comprises a pair of axially spaced fluid pockets, at least one raised land formed in at least one of the pair of fluid pockets, passage means for fluidically communicating the pair of fluid pockets with each other, throttle means connected to the fluid pockets for admitting pressurized fluid therein and an exhaust port formed on the raised land for discharging pressurized fluid. Exhaust means is formed on the bearing surface outside the pressure generating zones for discharging pressurized fluid.
