Abstract: A seal for a bearing includes a first annular retaining ring defining a first radially outermost portion and a second annular retaining ring defining a second radially outermost portion. The seal includes a resilient ring defining a third radially outermost portion. The resilient ring is disposed between the first annular retaining ring and the second annular retaining ring. The first radially outermost portion, the second radially outermost portion and the third radially outermost portion are aligned with one another. The resilient ring projects radially inward from the first annular retaining ring and the second annular retaining ring. The resilient ring is more compressible and flexible than the first annular retaining ring and the second annular retaining ring.

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.

Abstract: An anti-wear composite structure includes an anti-wear layer that has a wear surface opposite an adhesive receiving surface and a thermosetting resin applied to the adhesive receiving surface. The thermosetting resin includes a reactive adhesive configured to bond the anti-wear composite structure to a substrate at an ambient temperature band via pressure-sensitive adhesion. The thermosetting resin has an onset to cure in the ambient temperature band and has a peak cure temperature greater than the ambient temperature band to mechanically and chemically bond the anti-wear composite structure to a substrate.

Abstract: A loader slot bearing includes a housing and a truncated ball. The housing has an interior area that is defined by an inner bearing surface which has a concave contour defining a circumference. A single slot extends axially partway into the inner bearing surface and has a slot arc section area extending axially inward. The slot arc section area has a first circumferential slot-end, a second circumferential slot-end, and a slot arc length measured between the first circumferential slot-end and the second circumferential slot-end. A ratio of the slot arc length to the circumference of the interior area is about 0.20 to 0.35. The truncated ball has a convex exterior surface. The truncated ball is positioned in the slot and rotated so that the truncated ball is rotatably retained by the inner bearing surface. The truncated ball is angularly misalignable relative to the annular housing.

Abstract: A piston assembly for a lead-lag damper for a blade mounted on a rotor of a helicopter includes a piston-rod that has an inside surface and a piston-head that extends radially outward therefrom. The piston-rod has two ports extending therethrough on opposing sides of the piston-head. A sleeve is positioned in the piston-rod and has two annular passages that communicate with the respective ports. A valve spool is disposed in and slidingly engages the sleeve. The valve spool has a channel which is in variable fluid communication with two passages. The piston assembly includes a biasing member that biases the valve spool axially away from it. The channel has an axial width configured to variably regulate fluid flow between the two ports to control dampening of the piston-rod in response to centrifugal forces applied to the valve spool.
