1、 I 2150F2精轧机主传动系统设计 摘 要 本次毕业设计的设计对象是 2150F2精轧机主传动系统。 轧钢机主传动系统主要由电 动机、减速器、齿轮座、连接轴以及联轴节等组成。对于 2150 精轧机来说，其轧制要 求有较高的精度，板型要有较高的平整度，就要对轧机的各个部件进行精准的设计。该 论文主要以轧机的主传动为主题展开，对轧机主传动的设计就要求对于涉及到传动件的 各个部件如电动机、减速器、齿轮座、连接轴、联轴器等进行设计计算，需要对轧机的 轧制力、传动力矩和传动功率进行计算，对主电机容量进行选择，对设计好的主减速机 的齿轮、轴以及联接轴进行强度校核，直到满足要求。本文通过几次反复的计算已
2、满足 要求。设计好轧机的尺寸结构以后需要对润滑方式的进行选择，并对轧机的经济性、环 保性进行评估。当各个方面都满足时才是一个合格的设计。 关键词：主传动；设计；校核；减速机;润滑；环保 II The Design Of The Main Driver Of 2150F2 Finishing mill ABSTRACT The design of this graduation project is the main drive structure of 2150F2 finishing mill.
