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.

Hybrid bearing assembly with rolling elements and plain bearing

A track roller assembly includes a split inner ring, a split outer ring, a one piece inner ring and/or a one piece outer ring and a liner or plurality of rolling elements engaging therewith, the track roller assembly being disposed in a structure of an Airbus A-350 aircraft, an Airbus A-320 aircraft, an Airbus A320Neo aircraft, an Airbus A330 aircraft, an Airbus A330Neo aircraft, an Airbus A321 aircraft, an Airbus A340 aircraft, and an Airbus A380 aircraft.

Track roller bearings with rolling elements or liners

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.

Actuation system for a lift assisting device and lined track rollers used therein

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.

Corrosion resistant bearing material

An actuation system for deploying and retracting a lift assisting device of a wing of an aircraft, is presented. The actuation system includes a track pivotally coupled to the lift assisting device, a shaft rotating in response to flight control signals to deploy or retract the lift assisting device, means for actuating the lift assisting device between a retracted position and a deployed position along an arcuate path, a plurality of track roller bearings and a plurality of side roller bearings. The roller bearings rotatably contact the track to guide the track along the arcuate path. The track roller bearings are comprised of an outer ring, a split inner ring and liners disposed between bearing surfaces of the outer and the inner rings. The split inner ring is configured for accommodating deflection and bending of a mounting pin coupling the track roller bearing in proximity to the track.

Actuation system for a lift assisting device and roller bearings used therein

A bearing includes an inner race member having an end surface. An outer race member is disposed about the inner race member. The outer race member has an internal shoulder for engaging the end surface of the inner race member. The inner and outer race members are configured to define a raceway between them and to define a snap ring seat between them. There are cylindrical rollers in the raceway and a snap ring in the snap ring seat. The bearing may be provided as a follower head on a cam follower or may be eccentrically mounted on a drive shaft to serve as a cam. A bearing can be assembled by inserting the inner race member into the outer race member, disposing cylindrical rollers in the raceway and disposing a snap ring in the snap ring seat.
