Abstract: A roller assembly includes two outer rings rotatably mounted on a shaft by a respective set of rollers positioned between the shaft and each of the respective one of the outer rings. The shaft has a head flange on one end thereof and a groove formed therein at a distance from the head flange. A retainer ring is positioned in the groove and another retainer ring is secured to the shaft at a distance from the groove. The retaining ring is configured to space the two outer rings apart from one another so that the two outer rings are operable and rotatable independent from one another.

Abstract: A seal assembly for a bearing includes an inner seal member that has an annular ring with a first lobe extending therefrom and a seal receiving surface on a leg extending axially from the annular ring. The seal receiving surface has two seating areas. The seal assembly includes an outer seal member positioned radially inward from the leg and axially outward from the annular ring. The outer seal member has a pivot member which has a second lobe extending outwardly therefrom. The seal assembly includes a retaining ring that has a circumferential groove formed therein. The pivot member is pivotally seated in the groove so that the second lobe is moveable between the two first seating areas.

Abstract: An actuation system for deploying and retracting a lift assisting device of a leading edge of a wing of an aircraft including a track pivotally coupled to the lift assisting device. The track has first and second outer surfaces and side surfaces. The actuation system includes a shaft rotationally coupled within the wing of the aircraft and operable, in response to flight control signals, to deploy or retract the lift assisting device. The actuation system includes an actuator for actuating the lift assisting device, coupled to the shaft, between a retracted position to a deployed position along an arcuate path. The actuation system includes a plurality of track roller bearings rotatably contacting the first and second outer surfaces of the track to guide the track along the arcuate path. The plurality of track roller bearings includes one or more lined track roller assembly.

Abstract: A seal for a bearing includes an annular retaining ring defining a first radially innermost portion and a first radially outer end; and a resilient ring defining a second radially innermost portion and a second radially outer end. The first radially innermost portion and the second radially innermost portion are aligned with one another and together define a securing root of the seal. The root is adapted to seat in a groove of an inner ring of the bearing. The resilient ring projects radially outward from the annular retaining ring. The resilient ring is more flexible than the annular retaining ring. The second radially outer end defines a sealing surface adapted to slidingly engage an inner bearing surface of an outer ring of the bearing. The first radially outer end of the retaining ring terminates between the first radially innermost portion and the second radially outer end of the resilient ring.

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.
