摘  要

设计的轧钢机为400×2型轧钢机，轧辊的直径为400 mm，辊面长650mm.轧制力为100T。轧钢机主要用来为轧制小型线材，采用两辊式工作机座。轧机是实现金属轧制过程的设备。泛指完成轧材生产全过程的装备﹐包括有主要设备﹑辅助设备﹑起重运输设备和附属设备等。但一般所说的轧机往往仅指主要设备。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——分齿箱——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。分齿箱：其用途是传递转矩给工作辊，装在密闭的箱体内。联轴器：轴与轴之间的链接用联轴器。

Design of rolling mill is 400 ×2 type rolling mill, roll diameter is 400 mm, long 650mm. rolling force roll surface for100T. Rolling mill for rolling mainly to small wire, uses two rollers type working machine. Rolling mill is the realization of metal rolling equipment. A complete rolling production process equipment, including the main equipment, auxiliary equipment, lifting the transport equipment and ancillary equipment. But the general said mill often refers only to the main equipment. Rolling mill equipment is a major component of the mainframe out. Rolling machine mainframe is composed of a prime mover, transmission device and an actuating mechanism of three basic components. Allocation method used for electric motors -- -- -- mill reducer gear box. The roller to the irreversible and rotational speed, the original motivation for the introduction of the cost of a more rapid exchange of main motor. Taking into account the rolling load is uneven, in order to balance the load of the motor, reduce the electrical capacity, slowdown in the increase between a flywheel and electric motors. Gear box: its purpose is to transmit torque to the work roll, packed in a sealed box body. Coupling: the link between the shaft and the shaft coupling.
Key words：Rolling mill，gear seat，flywheel
