1、毕业设计(论文): 摘 要设计的轧钢机为3003型钢轧钢机，轧辊的直径为300 mm。轧钢机主要用来为轧制小型线材，采用三辊式工作机座。轧钢机的主要设备是由一个主机列组成的。轧钢机的主机列是由原动机，传动装置和执行机构三个基本部分组成的。采用的配置方式为电动机减速机齿轮机座轧机。由于轧辊的转向和转速不可逆转，原动机采用造价较底的高速交流主电机。考虑到轧制负荷很不均匀，为了均衡电机负荷，减少电机的容量，在减速机和电动机之间加有飞轮。齿轮机座：其用途是传递转矩给工作辊，设计采用三个直径相等的圆柱形人字齿轮在垂直面排成一排，装在密闭的箱体内。联轴器：在减速器与齿轮机座之间采用的是安全连轴器。而主联轴
