销轴联接开口机架多用于型钢轧机,机架有二辊式和三辊式的,机架结构如图一所示,机架的主要联接件为销轴,机架受到轧制力作用时,销轴受剪,变形较小,因此机架联接部份刚性比较大。其次是机架的联接件少,结构简单,换辊方便、迅速,其使用效果良好,但是这种机 Pivot coupling open rack and more for the steel rolling mill, the rack has two-roll and three-roll, the rack structure shown in Figure 1, the rack for the main link for the pin, when the role of the rolling force of the rack , Pin shear, deformation is small, so the rigidity of the rack connection is relatively large. Followed by the rack coupling less, simple structure, easy roll change, rapid, the use of good results, but this machine
