Embodiment Construction

[0030] Such as figure 1 As shown, an aircraft suitable for use in connection with the present disclosure is indicated generally at 100 . Aircraft 100 includes wings 102 secured to a fuselage 101 . Wing 102 also includes articulated aircraft wingtips 103, 103' (hereinafter "wingtips 103, 103'"). Wing tips 103 , 103 ′ are pivotally mounted on wing 102 by hinges 104 . in, figure 1 The element numbers 103 and 103' in are used to denote the minimum and maximum extended and flexed states of the wingtips 103, 103', respectively. As used herein, the term "wing tip" generally refers to an attachment configured to vary lift, and / or what is generally considered a wing tip by those skilled in the relevant art.

[0031] Hinge 104 comprises bearing 10, and it is for example with figure 2 The thrust bearing shown is similar to thrust bearing 10 . Such as Figure 2 to Figure 7 As shown, the bearing 10 includes an outer member 12 , an inner member 14 , a lubricating bushing 30 (eg, a...

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.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of U.S. Provisional Patent Application No. 62 / 260,794, filed November 30, 2015, and U.S. Provisional Patent Application No. 62 / 287,190, filed January 26, 2016, the contents of which are incorporated by reference in their entirety into this article. technical field [0003] The present invention relates to a thrust bearing for an articulated airfoil, and more particularly to a thrust bearing having a lubricated inner bushing and a preload member for axial movement within the bearing on the bushing. Sleeve wear remains within preset limits before and after. Background technique [0004] In the aerospace industry, airframe manufacturers seek methods and apparatus for maximizing fuel efficiency and minimizing cost (ie, improving economics) for various types of aircraft. In aerospace design, one aspect that manufacturers typically seek to optimize is the design of the airfoil. For fix...
