    • Successive roll stands in a rolling mill are driven at selectively different drive speed ratios by a transmission system having a pair of drive shafts and a least one idler shaft journalled for rotation about parallel axes. First and second gear trains each include intermeshed drive gears freely rotatable on the drive shafts, and a pair of idler gears on the idler shaft; each being in meshed engagement with at least one of the drive gears of each drive train. Clutches operated to selectively couple the drive gears of the first and second drive trains with their respective drive shafts.
    • 通过具有一对驱动轴的传动系统和围绕平行轴旋转的至少一个惰轮轴,以选择性地不同的驱动速度比驱动轧机中的连轧机架。 第一和第二齿轮系各自包括可在驱动轴上自由旋转的相互啮合的驱动齿轮和惰轮轴上的一对空转齿轮; 每个与每个传动系的至​​少一个驱动齿轮啮合。 离合器操作以选择性地将第一和第二驱动系的驱动齿轮与它们各自的驱动轴联接。
