    摘要： A spherical plain bearing includes an outer ring and an inner ring that are each coaxial with a longitudinal axis of the bearing. The outer ring has a first axial outer ring end, a second axial outer ring end, and an interior spherical concave bearing surface extending therebetween. The inner ring has a first axial inner ring end, a second axial inner ring end, and an interior cylindrical bearing surface defining a bore and an exterior spherical convex bearing surface extending therebetween. The exterior spherical convex bearing surface is in interfacial sliding engagement with the interior spherical concave bearing surface. A plurality of circumferential lubrication grooves and one or more curved lubrication channels are in the exterior spherical convex bearing surface. The curved lubrication channels are positioned to intersect each of the circumferential lubrication grooves. A plurality of profiled annular lubrication grooves circumferentially extend into the interior cylindrical bearing surface.

    摘要： A system for driving and guiding a trailing edge control surface arranged on a wing of an aircraft includes a first guide device attachable to the wing and coupled with an inboard section of the control surface for guiding the inboard section along a trajectory relative to the trailing edge region of the wing between a retracted position and an extended position, a second guide device attachable to the wing and holding a connecting means of an outboard section of the control surface, and a drive device attachable to the wing and the control surface for moving the control surface. The trajectory is a spatial path at least along one dimension, wherein a distance between the inboard section of the control surface and a fixed part of the wing changes during a motion of the inboard section on the trajectory.

    摘要： A conveyor belt transport system involves a driving shaft, a driven shaft, a pair of rollers, and a conveyor belt. The rollers each include a shaft hole running from one end to the other end and each end of the shaft hole is fitted with radial spherical plain bearings. The respective radial spherical bearings ride on the drive shaft and the driven shaft. The conveyor belt wraps around the rollers that, respectively, surround the driving shaft and the driven shaft. The two ends of both the driving shaft and the driven shaft each include belt wheels and the outer end of the belt wheels each include a guard board. The conveyor belt comprises a timing belt on an inner surface of each outside edge of the conveyor belt, and the inner surface of the timing belt includes concave teeth that matingly engage the belt wheels.

    摘要： A high-cycle, short range-of-motion linkage apparatus for actuation of a turbofan engine component includes a pivot member having a head portion and a stem, and an actuator moveable between a first and second position. An actuator first end defines a receiving portion into which the stem is removably secured. An actuator second end defines a coupling member pivotally connected to a turbofan engine structural member and moveable between a first and second position corresponding to the actuator first and second positions. A spherical plain bearing pivotally connects the pivot member head to the turbofan engine component and includes an inner member, an outer member swaged around the inner member and disposed between the inner member and the head of the pivot member, and a liner disposed between the inner and outer members. The outer member defines a range of motion in relation to the inner member up to 90°.
