The utility model discloses a sliding universal shaft of a silk rolling mill, which comprises a linkage ball at both ends, and a ball ball roller and an inner spline coat in the middle of the intermodal ball. The first linkage ball consists of the first linkage ball and the second linkage sphere; the first connection sleeve is installed in the spherical groove of the first linkage sphere, the spline shaft is installed in the other spherical groove of the first linkage sphere, the ball is installed in the ball of the ball ball, and the ball ball roller is installed in the inner hole of the spline shaft with the ball ball at the same time. The other end of the bead roller is installed in the spherical groove of the second linkage ball, and the second connecting shaft sleeve is installed in another spherical groove of the second linkage ball. The beneficial effect is that the spherical cross slider at both ends and the ball ball roller can slide at the same time in the spline sleeve, and the spherical sliding effect reduces the friction. Therefore, it can automatically eliminate the angular and axial deviation from the connecting shaft, eliminate the running hard knot and reduce the rotary gap, thus the stable operation of the rolling mill can be realized.

技术介绍
高品质游丝是高端手表机芯的弹性元件,其质量好坏对手表的定时精度有着很重要的影响,游丝与摆轮配合形成一个具有定值的和稳定的震动周期,而这个震动周期又是手表计时基准,因此走时的准确性与稳定性都与这个震动周期有着直接关系,而影响震动周期变化的很重要因素其中之一就是游丝的几何尺寸,游丝的高精度轧制是手表游丝生产中很重要的工艺过程,其游丝压轧机的运转稳定性在很大程度上决定着游丝的质量,随着产品档次的不断升级,对轧制设备各部件精度提高有着更高的要求,游丝在轧制过程中,影响产品精度的因素很多。图1是现有万向连轴器的平面示意图;万向连轴器设置在驱动齿轮箱与轧辊支撑轴中部,将二者连接。目前使用的是万向连轴器是十字销轴与方形夹块式结构,该结构涉及到轴结的灵活度、角向扭矩及夹块摩擦等,要想达到灵活度避免硬节现象需要放大各部间隙,但也会出现回转间隙偏大的弊病,另外,由于轴位差(驱动齿轮箱输出轴与轧辊支撑轴的中心距),带来的角向和轴向偏差容易产生的转动硬结现象,上述因素均会产生轧辊在转动中的径向 ...
