Publication number: 20150104124Abstract: A hermetically sealed damper assembly includes a sealed damper housing, a plunger, and a load transferring member coupled to the plunger. The sealed damper housing includes a body having a cavity and a resistive flow path defined therein. The cavity and resistive flow path are filled with a viscous fluid. The body includes a plurality of springs integrally formed therein. The plunger is disposed within the cavity, and separates the cavity into a first control volume and a second control volume. The resistive flow path provides fluid communication between the first and second control volumes. The plunger is coupled to the damper housing by the plurality of springs such that the springs provide a restorative force to the plunger. The load transferring member is configured to transmit mechanical loads to the plunger.Type: ApplicationFiled: October 11, 2013Publication date: April 16, 2015Applicant: General Electric CompanyInventors: Adolfo Delgado Marquez, Bugra Han Ertas, Darren Lee Hallman, Walter John Smith

Publication number: 20140376844Abstract: A wing foil bearing may include one or more wing or tab foil layers. A tab foil layer may comprise a thin material with a two-dimensional array of tab shapes. A tab shape may be defined by a boundary of material separated from the thin material and having an integral edge and a free edge. Tab shapes may include one or more free-state bends relative to the thin material, forming a two-dimensional array of cantilever wings or tabs. Tab arrays may be one or more of various types or two-dimensional arrays, and a tab foil layer may include additional tab arrays and tabs. One or more tab foil layers may be engaged with a mounting surface layer and a counter-surface layer to form a wing foil bearing. Tab foil layers may be stacked and or nested, including partial nesting and complete nesting.Type: ApplicationFiled: September 10, 2014Publication date: December 25, 2014Inventors: Erik E. Swanson, Patrick Shawn O'Meara

Publication number: 20140334753Abstract: A cylinder assembly includes a housing defining first and second outer cylindrical surfaces having a longitudinal axis and a shim having a retaining ring fitted over the first outer cylindrical surface. The shim includes a plurality of connector spokes extending from the retaining ring, and a corresponding plurality of shim elements configured at the ends of the plurality of connector spokes. The connector spokes extend radially from the retaining ring relative to the longitudinal axis when the shim is in a pre-installation configuration. The connector spokes are bendable such that the shim elements extend longitudinally and are positioned next to the second outer cylindrical surface when the shim is in an installation configuration. Shims, methods of assembly, bicycles and other components are also provided.Type: ApplicationFiled: March 14, 2014Publication date: November 13, 2014Applicant: KING CYCLE GROUP, INC.Inventors: CHRISTOPHER DALE KING, BRIAN KEITH SCHULTZ, ERIK STEVEN DREWS

Patent number: 8845195Abstract: A bearing element for a sliding bearing is configured to support a drive shaft of a hydraulic machine. The bearing element is connected to the drive shaft so as to prevent relative rotation and has an outer annular surface configured to provide sliding support. A supporting web is formed between a location at which the bearing element is fixed to the drive shaft and the outer annular surface. The supporting web is elastically deformable to compensate for deflection of the drive shaft and/or an alignment error of sliding bearings of the drive shaft. A sliding bearing has a bearing element of this kind, and a hydraulic machine has at least one sliding bearing of this kind.Type: GrantFiled: September 13, 2012Date of Patent: September 30, 2014Assignee: Robert Bosch GmbHInventor: Gerd Gaisser
