一、前言太钢第四轧钢厂ф760×1200毫米叠轧薄板轧机,主传动轴联轴器原设计为M3П-20半齿轮联轴器。实践证明,这种联轴器长期在重载与冲击频繁的条件下运转,并不能适应轧钢机工作的。多年来它暴露出不少弱点,其中感到最为棘手的是接手法兰盘连接螺栓经常松动、切断,螺栓孔磨成椭圆形。日久,使螺栓紧固更加困难。昼夜三班连续生产,班班都因紧固或更换螺栓而停车,由此可见接手对生产和产品质量的影响,仅处
I. Foreword TISCO fourth rolling mill ф760 × 1200 mm rolled sheet metal rolling mill, the main drive shaft coupling was originally designed for the M3П-20 semi-gear coupling. Practice has proved that this long-term coupling in the heavy load and impact of frequent operation, and can not adapt to the work of rolling mill. Over the years it exposed a lot of weaknesses, which felt the most intractable is to take over the flange bolts often loose, cut off, the bolt hole into an oval. As time goes by, making bolt fastening more difficult. Continuous production day and night three classes, classes are due to bolt fastening or replacement parking, we can see the impact on production and product quality, only at
