冷轧带钢平整机主传动系统设计

摘要

带钢经退火工序后，内部残余应力得到释放，板形变坏；同时，由于在退火炉中存放时间过长，带钢的表面质量会变坏。为改善上述缺陷，需进行带钢平整工艺。在这样的背景下，平整机应运而生。平整机用来在常温状态下，将经过冷轧并退火后钢卷，通过平整以提高带钢机械性能、改善带钢板形、提高带钢表面光洁度，获得符合要求的钢卷。本文先介绍了冷轧带钢生产工艺流程、冷连轧机组的发展及平整工序，接着引出平整机，阐述了平整机的作用、组成、工作原理等。接着对比选取了适当的电机、联轴器、减速器、齿轮座、连接轴。接着计算出了平整机的轧制力、轧制力矩及电机功率。在此基础上设计并校核了齿轮座中一对人字齿的参数，校核了轴上的危险截面，同时校核了轧辊强度，计算了轴承寿命。文末，大致介绍了平整机中常用的润滑、密封方式，介绍了平整机的经济性、环保性。
