我厂冷管车间二辊冷轧管机回转送进机构摇拐轴部分(图1)经常发生摇拐轴5在A处断裂和轴承6失效。 原结构壳体1绕OO轴线运动时,实现摆杆2的前后摆动。这是通过螺杆来调节摇拐轴5与壳体1的相对位置,从而达到改变摆杆的摆动幅度,调定轧机的送进量。 壳体1的作用力主要由摇拐轴5圆柱部分Ⅱ来传 Cold rolling plant in our factory two-roll cold-rolled tube rolling machine shaft into the body part (Figure 1) Rake shaft 5 is often broken at A and bearing 6 failure. When the original structure shell 1 moves around the OO axis, the swinging rod 2 can swing back and forth. This is through the screw rod to adjust the relative position of the rocker shaft 5 and the housing 1, so as to change the swing amplitude of the swing rod, set the mill’s feed. The force of the housing 1 is mainly transmitted from the cylindrical portion II of the rocking shaft 5
