摘要： 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.

摘要： A bearing monitoring system is provided including one or more bearings (308,310,312,314) within a flow passage (306) and a working fluid passing over at least one surface of the bearings. A first thermocouple (316) is located in the flow passage upstream relative to the one or more bearings (308,310,312,314) and configured to measure a first temperature of the working fluid and a second thermocouple (318) is located in the flow passage downstream relative to the one or more bearings (308,310,312,314) and configured to measure a second temperature of the working fluid. The system further includes a control device (328) in communication with the first thermocouple (316) and the second thermocouple (318), and configured to compute a temperature gradient across the one or more bearings (308,310,312,314) from the first temperature and the second temperature, compare the temperature gradient against a known value, and if the temperature gradient exceeds the known value, the control device is configured to provide an alert.

摘要： This invention relates to gas-lubricated sliding bearings used in rotor supports of high speed turbomachines. The bearing assembly comprises a radial foil bearing and an axial foil bearing, a control bearing preload device for controlling stiffness of the bearing under normal operating conditions, an electromagnetic unloading device for decreasing amplitude of rotor oscillations and an unloading means for increasing the ultimate bearing load without damaging bump foils. The radial foil bearing comprises a bushing 6 providing accommodating bearing misalignment with respect to the journal, an elastic member in the form of an elastic damping unit for increasing damping, which consists of a bump foil 20 and two smooth foils 16 and 22. The bump foils in the bearing have different heights and alternate in the axial direction to decrease wear under start/stop. A top foil 4 of the bearing is weldlessly retained within slots of mounting bars 70 and 80. The axial bearing has the bump foil with ridges circumferentially extended in order for the bearing to work in sealing mode. The top foils of the bearing are provided with circumferential slits in order to decrease thermal stress.

摘要： A foil thrust bearing forms the primary rotating interface for a film riding face seal. This face seal (10) includes a spring system (14, 20) that will allow the entire assembly to translate axially relative to a static attachment. The complete assembly will form a hybrid foil/film riding face seal that shows much promise at being sufficiently flexible to enable operation in a gas turbine engine. The seal includes a flexible top plate (22) having a non-flat surface under its working conditions, and a spring support system (14, 20) to allow the top plate to accommodate axial excursions and out-of-flat distortions.

摘要： A compliant foil fluid film thrust bearing including a thrust disk (24) rotor, fluid foils (40), spring foils (42), a thrust plate (28), and a housing (22) thrust surface. The non-rotating but compliant fluid foils (42), mounted on the thrust plate (28) and/or housing (22) thrust surface and positioned adjacent to the thrust disk (24), have open faced channels that induce regenerative vortex flow patterns in the process fluid. The multiple spring foils together provide a tilting pad support for the fluid folds but allow them to follow the axial and overturning motion of the thrust disk. The interaction of the tilting pad underspring supports and the circumferential fluid pressure gradients in the process fluid between the fluid foils and the thrust disk rotor assure that the fluid foils will assume hydrodynamically efficient convex shapes on the surfaces adjacent to the rotor regardless of the load applied to the thrust bearing.
