Slotted bearings with wear-resistant treatments for gearbox mounting in a geared turbofan engine
Abstract:
A load slot bearing system for a mounting system for a gearbox on a geared turbofan engine includes a load slot bearing assembly having a cobalt alloy inner member and a precipitation-hardenable alloy outer member. The inner member defines an outer engagement surface and the outer member defines an inner engagement surface slidably and rotatably engaged with the inner engagement surface. One of the outer engagement surface or the inner engagement surface has boron diffused therein. The load slot bearing system includes first and second slots extending inward from a face defined by the outer member, the second slot being positioned generally diametrically opposite the first slot. A first element is located in the bore of the inner member of the load slot bearing assembly and is connected to the inner member. A second element is connected to the outer member of the load slot bearing assembly.
