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.
