Involute gears were used for the reduction rears of hot-strip-rolling mills. The operating conditions are serious, and gear damage was frequently reported, presumably because of insufficient durabirity. Pinion stand gears of the rougher rolling mills in the Chiba 2nd hot-strip-rolling plant at this site also suffered from serious tooth damage, and a renewal project was undertaken. In the plan, a comparative study was made for conventional involute gear and W-N (Wildhaver-Novikov) gear which features high durability. As a result, W-N gears were introduced in 1985 for the first time as the plane-bearing-type reduction gears for hot-strip-rolling mills in Japan, and have been operating satisfactorily for 4 and a half years. In this report, the circumstances concerning the application of W-N gears, strength evaluation on the basis of root stress in actual rolling operation, and the operating condition are discussed.
