METHOD FOR REMANUFACTURING INTERNAL SPLINE COMPONENTS AND SPLINED CONNECTION

Abstract:

A remanufactured internal spline component includes an inner surface defining a cylindrical bore and a remanufactured internal geometry on the inner surface. The internal geometry has a maximum diameter and a minimum diameter. The remanufactured internal geometry is created by removing a worn internal geometry to a pre-cladding diameter, cladding the inner surface in a plurality of layers by laser cladding to produce a cladded surface, and machining the cladded surface to produce the remanufactured internal geometry.
