摘要： A surface processing method and power transmission component includes transforming a surface region of a metal alloy into a hardened surface region at a temperature that is less than a heat treating temperature of the metal alloy. The metal alloy includes about 11.1 wt % Ni, about 13.4 wt % Co, about 3.0 wt % Cr, about 0.2 wt % C, and about 1.2 wt % Mo which reacts with the C to form a metal carbide precipitate of the form M2C. The surface processing temperature, vacuum pressure, precursor gas flow and ratio, and time of processing are controlled to provide a desirable hardened surface region having a gradual transition in nitrogen concentration.

摘要： A surface processing method and power transmission component includes transforming by high current density ion implantation (high intensity plasma ion processing) a surface region of a metal alloy into a hardened surface region at a temperature that is less than a heat treating temperature of the metal alloy. The metal alloy includes between 1.5 wt % and 15 wt % Ni, between 5 wt % and 30 wt % Co, up to 1.0 wt % carbon, and up to 15 wt % of a carbide-forming element, such as molybdenum, chromium, tungsten, vanadium or combinations thereof, that can react with carbon to form metal carbide precipitates of the form M2C. The surface processing temperature, vacuum pressure, precursor gas flow and ratio, and time of processing are controlled to provide a desirable hardened surface region having a gradual transition in nitrogen concentration. A vapor deposition process deposits an amorphous hydrogenated carbon coating on the hardened surface region of the metal alloy. An intermediate coating between the coating and the hardened surface region promotes adhesion between the coating and hardened surface region.

摘要： There is a gear set. The gear set has a) a first gear having a first surface and b) an intermeshing second gear having a second surface. The first and second surfaces each, independently, have an isotropic arithmetic mean roughness, Ra, of about 3 microinches or less and are lubricated. There is also a method for increasing the contact surface-fatigue life of a gear set.

摘要： A split torque gearbox having multiple input shafts. Each input shaft is connected to two face gears. Each face gear is connected to two quill shafts, one is coaxially mounted and the second is not coaxially mounted. Of the two quill shafts, one is positioned on a first side of an output stage and a second quill shaft is located on a second side of the output stage and the quill shafts are connected thereto. The output stage is connected to a main shaft.
