Publication number: 20200141275Abstract: A bearing compartment for a gas turbine engine includes an engine static structure. A rotating structure is configured to rotate about an axis relative to the engine static structure. A bearing supports the rotating structure. A centering spring has first and second rings interconnected by axially extending circumferentially spaced beams. An aperture is provided between an adjacent pair of the beams. The first ring is mounted to the engine static structure. The bearing is mounted to the second ring. The first ring includes multiple circumferentially spaced lugs. Each of the lugs axially extend into a corresponding one of the apertures. The lugs include a support surface that engages the engine static structure.Type: ApplicationFiled: November 7, 2018Publication date: May 7, 2020Inventors: Christopher T. Anglin, Kaleb Von Berg

Patent number: 10570776Abstract: 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.Type: GrantFiled: June 7, 2016Date of Patent: February 25, 2020Assignee: United Technologies CorporationInventors: Kaleb Von Berg, Christopher T.

Patent number: 10458277Abstract: 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.Type: GrantFiled: July 20, 2018Date of Patent: October 29, 2019Assignee: United Technologies CorporationInventor: Kaleb Von Berg

Patent number: 9869206Abstract: 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.Type: GrantFiled: June 21, 2016Date of Patent: January 16, 2018Assignee: United Technologies CorporationInventor: Kaleb Von Berg

Patent number: 9702404Abstract: An assembly includes a centering spring having an annular flange, an annular body, and a plurality of resilient beams extending from the flange to the body. The annular flange defines a passage that extends at least radially inward with respect to a centerline circumscribed by the flange from a radially outer surface of the flange to a radially inner surface of the flange. The annular body is spaced from the flange along the centerline, a radially outer surface of the body forming a first annular cavity relative to an adjacent surface configured to be a first fluid damper. A deflection of the body relative to the flange is restrained by a restoring force produced by the plurality of resilient beams and the first fluid damper. A method includes providing the aforementioned assembly and passing a damping fluid through the passage of the flange.Type: GrantFiled: October 28, 2015Date of Patent: July 11, 2017Assignee: United Technologies CorporationInventors: Adam G.
