ACTUATION SYSTEM FOR A LIFT ASSISTING DEVICE AND ROLLER BEARINGS USED THEREIN

摘要

An aircraft wing (12) includes a wing structure (12a), a slat panel (16) mounted on a track (18), and an actuator mechanism (26) on the wing structure coupled to the track for moving the slat panel between a deployed position and a retracted position. Track roller bearings (38) on the wing structure rotatably contact the track, and side roller bearings on the wing structure rotatably contact at least one side of the track. In another configuration, the actuator mechanism includes a shaft rotatably mounted on the wing structure, an actuator arm coupled to the track by a bearing linkage, and an actuator lever coupled to the shaft by a bearing linkage and to the actuator arm by a bearing linkage. At least one bearing linkage includes a spherical plain bearing.
