摘要： An actuation system for deploying and retracting a lift assisting device (20) of a wing (10) of an aircraft (8), is presented. The actuation system includes a track (50) pivotally coupled to the lift assisting device (20), a shaft (90) rotating in response to flight control signals to deploy or retract the lift assisting device (20), means (70, 80, 120, 130) for actuating the lift assisting device (20) between a retracted position (20') and a deployed position (20") along an arcuate path (A), a plurality of track roller bearings (100) and a plurality of side roller bearings (300). The roller bearings (100, 300) rotatably contact the track (50) to guide the track (50) along the arcuate path (A). The track roller bearings are comprised of an outer ring (210), a split inner ring (220) and liners (250) disposed between bearing surfaces (212, 214, 222, 224, 226, 228) of the outer (210) and the inner (220) rings. The split inner ring (220) is configured for accommodating deflection and bending of a mounting pin (150) coupling the track roller bearing (100) in proximity to the track (50).
