In the 1980’s, Advanced Technology Gear (ATG) steel rollingmillgear drives consisting of carburized pinions in mesh with verylarge, weld fabricated, high through hardened gears were introducedto improve capacity. Recently, even the improvements obtained fromthese ATG gear sets were not sufficient to meet higher productionrates and rolling loads. For greater load capacity ATG sets havebeen developed consisting of carburized, hardened pinions in meshwith very large, weld fabricated, carburized and hard finishedgears. Single and double helical gears of this type, ranging insize from 80 to 136 inches pitch diameter have been implemented inseveral steel rolling applications. This paper describes theconditions that require the use of these gears and the technologyrequired to design, manufacture, and, especially, heat treat, thesevery special, very large gear sets.
