摘要： Embodiments disclosed herein relate to bearing assemblies and methods of manufacturing. In an embodiment, a bearing assembly includes a support ring and bearing elements. The bearing elements are mounted to and distributed circumferentially about an axis of the support ring. At least one of the bearing elements includes a polycrystalline diamond table, a substrate bonded to the polycrystalline diamond table, bonding region defined by the substrate and the polycrystalline diamond table, and a corrosion resistant region. The corrosion resistant region includes a corrosion resistant material that covers at least a portion of at least one lateral surface of the bonding region. The corrosion resistant region prevents corrosion of at least some material in the bonding region covered by the corrosion resistant region ( e.g., during use). Other embodiments employ one or more sacrificial anodes as an alternative to or in combination with the corrosion resistant region.

摘要： Exemplary embodiments disclosed herein include bearings with three races: an inner race, a shared race, and an outer race that exhibit increased life under oscillatory loads. The exemplary embodiments may include one or more directional biasing mechanisms configured such that when a bearing shaft rotates in one direction, the shared race rotates with it, and when the shaft oscillates in the other direction, the shared race is impeded from moving in the other direction. Under continued oscillation, the shared race will "walk" in circles around the shaft, effectively distributing the load and wear over the entire circumference of a bearing surface.
摘要翻译：本文公开的示例性实施例包括具有三个种族的轴承：内圈，共享座圈和外圈，其在振荡载荷下表现出增加的寿命。示例性实施例可以包括一个或多个定向偏置机构，其构造成使得当轴承轴在一个方向上旋转时，共享的座圈与其一起旋转，并且当轴在另一个方向上摆动时，共享的座圈被阻止在另一个方向上移动方向。在持续振荡的情况下，共享的比赛将围绕轴围绕“行走”，有效地分布负载和磨损在轴承表面的整个圆周上。

摘要： A compliant support for an axial thrust air bearing between a shaft and a housing with an annular thrust runner extending radially from the shaft having a runner bearing surface. The housing has a housing bearing surface and an air inlet in communication with a source of pressurized air. An annular foil support sleeve is disposed on the housing bearing surface, having an air foil surface with an array of foils. The foils serve to conduct air from the air inlet forming a pressurized air curtain between the runner bearing surface and foils on the the sleeve and is then disposed of through an air outlet. The sleeve has a compliant surface with at least one compliant annular ring. The compliant surface includes at least one compliant annular ring such as a fluorocarbon O-ring for low temperature service under 300 F; (149 C); a fluorosilicon O-ring for mid-range temperature service 300-600 F (149-298 C); or a metallic mesh ring for high temperature service over 600 F (298 C).

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： The top foil (12) of a hydrodynamic fluid film thrust bearing (10) is formed from a single flat annular disk with radial depressions (30) extending from the outer diameter to the inner diameter of the disk that protrude toward the foil plate (16) and define between adjacent depressions a working surface (39) that is configured to complement the foil bumpers (14) attached to the foil plate. The bump foils of the upper foil plate and the bump foils of the lower foil plates can be either in axial alignment or can be displaced relative to each other. When the two sets of bump foils are displaced, the leading edge (31) of the upper bump foils is disposed upstream (relative to the direction of the air stream entering the bump foils) of the leading edge (33) of the lower bump foils.
