摘要： Driving apparatus for a rolling mill includes upper and lower work rolls for rolling a workpiece having a longitudinal axis lying in a horizontal plane, upper and lower driving shafts for driving the upper and lower work rolls, respectively, an upper universal joint operatively coupling the upper work roll to the upper driving shaft, and a lower universal joint operatively coupling the lower work roll to the lower driving shaft. The upper and lower work rolls have axes lying in planes parallel to the horizontal plane of the workpiece longitudinal axis and are slanted in opposite directions with respect to the longitudinal axis of the workpiece. The upper and lower driving shafts are disposed symmetrically with respect to the horizontal plane of the workpiece longitudinal axis and a vertical plane passing through the workpiece longitudinal axis. The upper and lower universal joints have yokes at angles which are 90 degrees out of phase with each other, whereby the phase angles of the corresponding upper and lower universal joints are 90 degrees out of phase and the rotation speeds of the upper and lower work rolls are equalized.

摘要： A support assembly for coupling of a large-sized universal joint of the cardan type as incorporated in a drive assembly for rolling mills. The assembly supports the coupling on a drive spindle portion to prevent the coupling from hanging. A locking rod fixed to the center of the coupling extends through a hole of large diameter formed in the center of the spider of the universal joint, with a sufficient radial clearance provided between the rod and the inner periphery of the spider. The piston rod of a hydraulic cylinder disposed within an inner bore of the drive spindle portion operates to slidingly move a rod receiving member within the bore, thereby bringing a recess portion of the rod receiving member into engagement with or disengagement from the free end of the locking rod. The coupling is securely supported on the drive spindle portion by the engagement of the rod receiving member with the locking rod.
摘要翻译：一种用于联接万向节万向接头的支撑组件，其结合在用于轧机的驱动组件中。组件支撑在驱动主轴部分上的联接，以防止联接悬挂。固定在联轴节中心的锁定杆通过形成在万向接头的蜘蛛的中心的大直径的孔延伸，并且在杆和内周之间设有足够的径向游隙。设置在驱动主轴部分的内孔内的液压缸的活塞杆操作以将杆接收构件滑动地移动到孔内，从而使杆接收构件的凹部与第二杆的自由端接合或脱离锁杆。通过杆接收构件与锁定杆的接合，联接件牢固地支撑在驱动主轴部分上。
