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.

A method for the manufacture of a gear component includes, in a soft machining process, introducing a preliminary toothing 3 with a machining allowance 7 that is fixed relative to a final toothing 4 into a blank such that a semi-finished part 2 is produced. The method also includes, in a fine machining process, removing the machining allowance 7 and producing the final toothing 4 of the toothed component. The machining allowance 7 is removed in a single-stage hobbing method by a grinding tool 1, wherein the grinding tool 1 removes the machining allowance completely in a single stroke movement H.

The invention concerns a process for the assembly of an epicyclic or planetary gear train of a planet gear carrier comprising one or more bores, each of the bores being intended to receive a pivot (18), the process comprising the following steps: a) manufacturing of at least one pivot (18) comprising a real axis (46) distinct from a theoretical axis; b) measuring the position of a real axis of each of said one or more bores of the carrier; c) for each bore of the carrier, mounting a pivot (18) in said bore and orienting it angularly so that the eccentricity of the pivot (18) at least partially makes up for the eccentricity of said bore.

Provided is a sprocket having a body formed by a powder metallurgy process with a predetermined density and vibration energy absorbing properties, and teeth with a greater density than the density of the body, and a method of making the same. The sprocket minimizes mechanical vibration during a chain-to-sprocket tooth contact. The teeth of the sprocket have a higher density than the body of the sprocket.

A method that includes: providing a blank; heating the blank; forging the heated blank to form a forged gear having a plurality of spiral bevel gear teeth; machining the forged gear to a predetermined thickness while locating off of the plurality of gear teeth to form a green machined forged gear; rotationally and axially engaging a die to the gear teeth of the green machined forged gear to induce plastic flow in the gear teeth to form an intermediate gear in which the plurality of gear teeth conform to a predetermined tooth form; heat-treating the intermediate gear to form a hardened intermediate gear; and lapping the plurality of gear teeth of the hardened intermediate gear with a spiral bevel pinion gear; wherein the plurality of gear teeth are not machined in a chip-producing machining operation before the plurality of gear teeth are lapped.
