Abstract: A bearing system for a rotating vertical shaft includes a first ball bearing, having a first pitch diameter and a first axial stiffness and a second ball bearing having a second pitch diameter and a second axial stiffness. The first ball bearing is a deep groove Conrad bearing. The second ball bearing is an angular contact bearing. The first and second ball bearings are coaxial, secured to one another and rotatable together. The first pitch diameter is at least 1.5 times greater than the second pitch diameter. The bearing system has an axial stiffness ratio defined by the first axial stiffness divided by the second axial stiffness. The axial stiffness ratio is based on an axial preload force applied to the second outer ring such that an operating torque of the bearing system is within a predetermined range at temperatures from minus 40 to positive 85 degrees Celsius.

Abstract: A composite material having an alloy matrix including titanium, aluminum, niobium, manganese, boron, and carbon is disclosed. The composite material includes, by atomic percentage, 40.0% to 50.0% Al, 1.0% to 8.0% Nb, 0.5% to 2.0% Mn, 0.1% to 2.0% B, and 0.01% to 0.2% C. The composite material is doped with a solid lubricant such as MoS2, ZnO, CuO, hexagonal boron nitride (hBN), WS2, AgTaO3, CuTaO3, CuTa2O6, or combinations thereof. Components composed of the composite material exhibit increased ductility at room temperature and reduced fracture tendency, resulting in improved durability.

Abstract: A spheroidal joint for a tuned mass damper system includes a base having a concave seat and a lubricious liner secured thereto. The base defines a first mounting portion under the concave seat and a circumferential rim opposite the first mounting portion. The concave seat tapers radially outward to define a chamfer which terminates at a radially inner edge of the rim. The spheroidal joint includes an inner member that has a convex seat. The inner member has a second mounting portion extending from the convex seat and an indentation circumferentially extending around the inner member between the convex seat and the second mounting portion. The indentation cooperates with the chamfer for misalignment of the inner member relative to the base. The convex seat slidingly engages the lubricious liner.

Abstract: A cage for an hourglass roller bearing includes an annular ring having a first axial face and a second axial face. A plurality of first rails extend from the first axial face and a plurality of second rails extend from the second axial face. The cage includes a plurality of pockets. Each of the plurality of pockets is defined by opposing circumferentially facing walls of at least one of adjacent pairs of the first rails and adjacent pairs of the second rails. The circumferentially facing walls are arcuately formed so that each of the plurality of pockets is cylindrical.

Abstract: A bearing for a hinge in a hinged raked aircraft wing tip includes an outer member that has a concave inner surface and an inner member that has first and second inner segments. Each of the first and second inner segments has a base that has a bearing section extending therefrom. The bearing sections together form a convex outer surface that is complementary in shape to the concave inner surface. A preload feature is positioned between and engages a portion of the bearing sections. A lubricous liner is positioned between the concave inner surface and the convex outer surface. The bearing sections are positioned in the outer member to compress the preload feature to limit axial movement between the outer and inner members to a predetermined magnitude. The preload feature flexes outward as a result of wear to the liner to maintain the axial movement to the predetermined magnitude.

Abstract: An edge flap arrangement for an aircraft wing includes a main flap element and an actuator for moving the main flap element relative to the aircraft wing. A linkage arrangement supports the main flap element and includes a drop hinge link arrangement having a fixed strut secured to the aircraft wing and a drop link secured to the main flap element. The fixed strut and the drop link are connected by a hinge point having an hourglass bearing assembly having hourglass shaped rollers with a circular cross section symmetrical about a longitudinal axis, first and second axial ends, and an exterior surface. The exterior surface defines a concave engagement surface having a first radius of curvature R1 and a second radius of curvature which is greater than the first radius of curvature R1. The first radius of curvature is between 50 and 95 percent of the second radius of curvature.
