一种粗轧机轧辊轴向固定装置及粗轧机
摘要：
本实用新型公开了一种粗轧机轧辊轴向固定装置及粗轧机，包括设置在轧辊的凹槽的螺纹半环，通过板销与所述螺纹半环连接的圆螺母，板销通过紧定部件固定在圆螺母，板销的用于设置紧定部件的一端的宽度小于用于固定螺纹半环的一端的宽度。如此设置，可以减小板销的旋转重心与轧辊的轴心的距离，以减小板销的离心甩出趋势，进而减小板销的变形，提高板销的使用寿命。
摘要（英）：

The utility model discloses a roughing mill roller axial fixing device and a roughing mill. The roughing mill roller axial fixing device comprises a threaded half ring and a round nut, wherein the threaded half ring is arranged in a concave groove of a roller, and the round nut is connected with the threaded half ring through a plate pin, the plate pin is fixed on the round nut through a fastening part, and the width of one end, used for being provided with the fastening part, of the plate pin is smaller than the width of the other end used for fixing the threaded half ring. Through the arrangement, the distance between the rotation gravity center of the plate pin and the axis of the roller can be reduced, the centrifugation throwing-out trend of the plate pin is reduced, the deformation of the plate pin is further reduced, and the service life of the plate pin is prolonged.
