为了减少轧制带材纵向的厚度偏差,希望将轧机工作机座的弹性变形值(即弹跳)保持最小。机座的弹性变形值为一系列另件的弹性变形量之和,其中大致有以下的比例关系:机架——12～17%;支承辊和工作辊——50～55%;支承辊轴承——13～15%;压下机构——15—16%; 轴承座和垫板——3～4%。这些比例关系决定了在现代薄板轧
In order to reduce the longitudinal thickness of the rolled strip, it is desirable to minimize the amount of elastic deformation (ie bouncing) of the working stand of the rolling mill. The elastic deformation of the base is the sum of the elastic deformations of a series of other components, which are roughly the following ratio: rack - 12-17%; backup roll and work roll - 50-55%; backup roll bearing - 13 ~ 15%; Pressing mechanism - 15-16%; bearing seat and pad - 3 ~ 4%. These proportions determine the rolling of modern sheet metal
