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°.

摘要： A high-cycle, short range-of-motion linkage apparatus is provided for actuation of a positioning device. The linkage apparatus includes a pivot member having a stem extending therefrom, a positioning member including a receiving portion into which the stem is removably secured, and at least one spherical plain bearing secured to the pivot member. The spherical plain bearing has an inner member having an outer engagement surface and a bore extending at least partway therethrough, an outer member positioned at least partially around the inner member, the outer member having an inner engagement surface contoured to a shape complementary to the outer engagement surface of the inner member, and a liner disposed between the inner engagement surface of the outer member and the outer engagement surface of the inner member, the liner comprising polytetrafluoroethylene and a phenolic resin reinforced with aramid fibers.
