Abstract:
A guide mechanism, configured for use with a guided attack rocket, includes an inner housing partially disposed in an outer housing. The inner and outer housings each define a forward end and an aft end. A first angular contact bearing is positioned between the outer housing forward end and the inner housing forward end. A second angular contact bearing is positioned between the outer housing aft end and the inner housing aft end. A retaining nut is received over the inner housing forward end. The retaining nut preloads the first and second angular contact bearings. Each of the angular contact bearings includes an inner member disposed within an outer member. The outer member defines an outer raceway and the inner member defines an inner raceway. A plurality of rolling elements is disposed between the outer raceway and the inner raceway.
Abstract:
A swaged bearing assembly includes a flange mounted thereon. A bearing inner member has an outer surface at least a portion of which defines an outer engagement surface. A bearing outer member is swaged around the inner member and the inner member is misalignable and rotatable in relation to the outer member. The outer member has an outer surface and an inner surface at least a portion of which defines an inner engagement surface. An area of engagement is defined by an interface of the inner engagement surface of the outer member and the outer engagement surface of the inner member. A flange is mounted on the outer surface of the outer member.
Abstract:
A sealed spherical bearing includes a ball disposed in a race, an annular seal extending between the race and the ball, and a retainer secured to the seal. A retainer first leg axially outward facing surface is secured to a seal first leg axially inward facing surface, and a retainer second leg radially inward facing surface is secured to a seal first leg radially outward facing surface. The retainer and the seal are separately formed elements. The retainer and the seal secured thereto is press-fit into a first annular groove of the race such that a first groove radially inward facing surface engages a retainer second leg radially outward facing surface, a first groove axially outward facing surface engages a retainer first leg axially inward facing surface, and the retainer is fixed relative to the race.
Abstract:
An edge flap arrangement is provided for an aircraft wing and includes a main flap element and an actuator for moving the main flap element relative to the wing. A linkage arrangement supports the main flap element from the aircraft wing for movement relative to the wing, and includes including 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 drop link are pivotally connected by a hinge point having a bearing installed therein. The bearing includes an outer race, an inner race and an annular seal assembly snap-fit into the outer race. The annular seal assembly includes first and second annular retaining rings and a resilient ring disposed between the first and second annular retaining rings.
Abstract:
A bearing assembly has an outer race, which has an arcuate inner surface and an inner member that is partially disposed in the outer member and which has an arcuate outer surface. The inner member has one or more hubs that extend axially from the inner member. The one or more hubs each have one or more circumferentially extending surface depression that is positioned proximate the arcuate outer surface. The one or more hubs each have one or more circumferentially extending surface protrusion that is positioned axially outward beyond the at least one circumferentially extending surface depression.
Abstract:
A bearing assembly includes an outer race having an inner surface defining a concave contour and an inner race positioned in the outer race. The inner race has an inner surface defining a bore therethrough and an outer surface defining at least one groove circumscribing the outer surface. A plurality of rolling elements is rollably located in the groove and is in rolling contact with the inner surface of the outer race. A lubricious liner has an inner liner-surface and an exterior liner-surface, the exterior liner-surface being disposed on the inner surface defining the bore. The lubricious liner has a modulus of compression of a magnitude sufficient to allow misalignment of the inner liner-surface relative to the exterior liner-surface in response to a force applied thereto.
Abstract:
In one aspect, the present invention resides in an edge flap arrangement for an aircraft wing that has a main flap element and an actuator for moving the main flap element relative to the wing, a linkage arrangement that supports the main flap element from the aircraft wing for movement relative to the wing, the linkage arrangement including a drop link and a hinge point. The fixed strut and the drop link are pivotally connected by the hinge point. The hinge point includes a bearing. The bearing is an hourglass bearing assembly that has an inner raceway outer raceway. The outer raceway is positioned around the inner raceway. A plurality of rollers is disposed between the inner raceway and the outer raceway. The plurality of rollers, the outer raceway and/or the inner raceway are manufactured from CREN and/or CRES.
Abstract:
A cage for a roller bearing includes a first annular portion and a second annular portion opposite the first annular portion and a plurality of pillars interconnecting the first annular portion and the second annular portion. Adjacent pairs of the pillars each define a pocket for holding rollers. Each of the pockets is configured to receive at least one roller. One or more radially outward facing concave roller support surface is formed in one or more of the pillars at a position proximate a radially outer edge of the pillar. The concave roller support surface is configured to radially outwardly support a portion of one of the rollers.

The annular seal assembly includes first and second annular retaining rings and a resilient ring disposed between the first and second annular retaining rings.
Abstract:
A seal for a bearing includes a first annular retaining ring defining a first radially outermost portion and a second annular retaining ring defining a second radially outermost portion. The seal includes a resilient ring defining a third radially outermost portion. The resilient ring is disposed between the first annular retaining ring and the second annular retaining ring. The first radially outermost portion, the second radially outermost portion and the third radially outermost portion are aligned with one another. The resilient ring projects radially inward from the first annular retaining ring and the second annular retaining ring. The resilient ring is more compressible and flexible than the first annular retaining ring and the second annular retaining ring.
