Abstract
A self-lubricating bearing assembly for a hinge of a turbine engine nozzle is described. The hinge includes a bolt and a bell crank housing. The bearing assembly includes a sleeve, a pair of bushings, liners, a thrust washer and a nut. The sleeve includes a tubular and a shoulder portion. Each bushing has an inner and an outer diameter. The liners include first liners, each bonded to the inner diameter of a respective one of the bushings, a second liner disposed between the shoulder portion and a bushing, and a third liner disposed between the thrust washer and a bushing. When assembled, the tubular portion is disposed over an outer diameter of the bolt, the outer diameters of the bushings are disposed within an inner diameter of the bell crank housing, and the nut is affixed between the thrust washer and the bolt to secure the hinge assembly.
