Abstract
A bearing is mounted for rotation on a shaft, the bearing having a projected area in both the axial and radial directions. A fixed bearing support housing is mounted adjacent to and spaced from the bearing and forms an annular space for a fluid flow path extending both radially and axially around the bearing to provide a hydrostatic film barrier which centers the shaft during steady state operation. A plurality of reversing fluid jets in the bearing support housing communicate with such annular space. A pair of non-rotating split rings are located forward and aft of the bearing, the split rings each having a taper angle on its inner circumferential surface. A garter spring is mounted in a recess in the outer circumference of each ring and forces the outer edge of the tapered surface into contact with a hardened surface area on the shaft or on a sleeve mounted on the shaft, to support and center the shaft in the transient state and during start-up and shut-down operations. Annular passsages communicate with the annular space around the bearing and with the space formed by the taper angle of the split rings so that when high pressure fluid flows into contact with the taper angle on t…
