Abstract
A fluid bearing system for journalling a shaft against radial and/or axial loads. The described bearing consists of a housing having at least one fluid compression chamber. The housing surrounds the shaft and is provided with at least one portion which is stationarily fixed with respect to the shaft. Inlet means are provided through the stationary portion for the introduction of air or liquid. A ring securely fixed to the shaft for rotation therewith extends in opposition to the stationary portion. The ring forms with a surface of the stationary portion a throttling gap between the inlet and the compression chamber by which the restriction of fluid flow is accomplished.
Claims12
A fluid bearing for a rotary shaft comprising a housing surrounding said shaft and forming at least one annular compression chamber on the interior surface thereof, at least one portion of said housing being annular and fixed stationary with respect to said shaft and having conduit means for the inlet of fluid under pressure to said chamber, a ring secured to said shaft for rotation therewith and extending within said compression chamber in spaced opposition to said stationary portion, having a peripheral surface coacting with said annular portion to divide said compression chamber into laterally spaced sections, said ring forming with the surface of said stationary portion a circumferential compression space and lateral throttling gaps between the inlet conduit and said lateral sections of the compression chamber for restriction of fluid flow under both radial and axial loads.
