φ300轧钢机论文大学毕业设计.doc

摘 要 设计的轧钢机为Ф300型钢轧钢机，轧辊的直径为300mm。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。而主联轴器采用的的梅花接轴联轴器。 关键词：　轧钢机；齿轮机座；轧辊 Abstract Rolling mill designed for Ф300 payments rolling mill, roller diameter of 300 mm. Rolling mill for rolling mainly to small wire rod, a three roller-working machine Block. Rolling mill equipment is a major component of the mainframe out. Rolling mill is the former mainframe is motivated transmission devices and the three basic components of the implementing agencies. Allocation method used for electric motors -- slowdown plane -- plus seat -- rolling mill.The roller to the irreversible and rotational speed, the original motivation for the introduction of a more rapid exchange of the costs of Electrical. Taking into account the rolling load is uneven, to balance electrical loads and reduce the electrical capacity slowdown in the increase between a flywheel and electric motors. Flywheel design and installation of electric motors in decelerator between its role in the adoption roller and roller idling, a mobile storage device in a balanced transmission loads; gear seat : its purpose is to transmit torque to the work revolve, the equivalent diameter cylindrical design used three words plus people lined up in the vertical plane, packed in sealed .Shaft coupling : in the Block reducer and gear is used between security company axle vehicles.
