摘 要 摘要：设计的轧钢机为300×3型钢轧钢机，轧辊的直径为300 mm。轧钢机主要用来轧制小型线材，采用三辊式工作机座。轧钢机的主要设备由原动机，传动装置和执行机构三个基本部分组成。采用的配置方式为电动机→减速器→齿轮机座→轧机。 原动机采用造价较底的高速交流主电机。减速器选取二级标准减速器。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，装在密闭的箱体内而主联轴器采用梅花接轴联轴器。 关键词Abstract The Designation Of There Rolling Wire Rod Mill Rolling mill designed for 300 x 3 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. Keywords: Rolling mill; gear seat; flywheel. 目 录 摘 要 I Abstract I 1 绪论 1 1.1研究背景与意义 1 1.2本课题在国内外的研究现状 1 1.2.1 国外相应机器的研究状况 2 1.2.2国内相应机器的研究状 2 1.3线材轧钢机的用途及工作原理 2 1.3.1线材轧钢机的用途 3 1.3.2线材轧钢机的工作原理 3 2 轧制力和轧制力矩的计算 5 2.1轧制平均单位压力的确定 5 2.2轧制总压力的确定 7 2.3轧制力矩的确定 8 2.4电机的选择 8 3飞轮的设计 9 3.1飞轮力矩的确定 9 3.2飞轮强度的校核 11 4 减速器的选择 12 4.1 传动比的计算 12 4.2标准二级圆柱齿轮减速器的选择 12 5 齿轮机座的设计 13 5.1 齿轮机座的类型和结
