Abstract (en)
[origin: EP2436487A1] The present invention is directed to a method and apparatus for processing a metallic gear (20) comprising providing a gear (20), directing a first peening media at the metallic gear (20) thereby exposing a plurality of surfaces on the metallic gear (20) to the first peening media whereby the strength and wear properties of the teeth roots of the gear (20) are enhanced, directing a second peening media at the metallic gear (20) thereby exposing a plurality of surfaces on the metallic gear (20) to the second peening media whereby the surface compressive stress of the gear (20) is enhanced, providing a container (200), placing a fine finishing medium (212) in the container (200), placing the gear (201) with the fine finishing medium (212) in the container (200), coupling vibrations to the container (200) to vibrate the fine finishing medium (212) with the wetted gear (20), removing the gear (20) from the container (200), washing the gear (201) and rinsing the gear (20) with rust inhibitor.
