Abstract: An assembly is provided for a piece of rotational equipment with an axis. This assembly includes a static structure, a bearing within a bore of the static structure, and a centering spring mounting the bearing to the static structure. The static structure is configured with the bore, a slot, a first slot surface and a second slot surface. The slot extends radially into the static structure from the bore. The slot extends axially within the static structure between the first slot surface and the second slot surface. The centering spring includes an annular hub and a mounting tab. The annular hub is within the bore. The mounting tab projects radially from the annular hub into the slot.

Abstract: A system is provided that includes a support structure and a nozzle. The support structure includes a cavity surface and an aperture. The cavity surface at least partially forms a boundary of a cavity. The aperture extends partially into the support structure from the cavity surface. The nozzle includes a mount, a neck and a head. The mount is seated within the aperture. The neck is connected to the mount and extends axially along a centerline away from the surface to the head. The head is configured to inject fluid out of the nozzle and into the cavity.

Abstract: A bearing assembly comprises a housing that includes a first housing surface and a second housing surface. The first and second housing surfaces are substantially axially parallel with respect to a rotor centerline. The bearing assembly also comprises a damped outer race that includes a first outer race surface radially adjacent to and opposing the first housing surface which is located radially interior to the first outer race surface. A second outer race surface is radially adjacent to and opposing the second housing surface which is located radially exterior to the second outer race surface. The housing comprises an oil passage that is configured to provide oil from an outlet to a first space between the first outer race surface and the first housing surface, and configured to provide oil to a second space radially between the second outer race surface and the second housing surface.
