第 IV 页鞍山科技大学本科生毕业设计（论文）圆盘剪切机设计摘 要现在各国工业迅猛发展，钢铁企业是国民经济的主要支柱，它的发展状况很大程度上可以反映出国家的实力。现代钢铁冶金业发展的一个着眼点就是在对钢材的处理速度。圆盘剪切机就是其中的一台重要设备。圆盘剪切机通常设置在精整作业线上，用来将运动着的钢板的纵向边缘切齐或切成窄带钢。根据其用途可分为两种类型：剪切板边的圆盘剪和剪切带钢的圆盘剪。本文中对圆盘剪切机的设计计算是在对鞍山钢铁集团公司冷轧厂1700横切机组大量调研的背景下进行的。通过对圆盘剪切机及相关设备结构进行了深入了解，并从材料力学、动力学和经济学的角度出发，对圆盘剪切机的主传动系统，压下系统、侧间隙调整机构进行了设计。重点包括电动机的计算选取、轴和齿轮的设计，以及其他传动装置和执行机构的设计等，同时对部分主要零部件进行了强度校核。本次设计的改进点：首先，在径向间隙调整机构连杆机构，其二，侧向间隙调整增加自锁装置。其三，宽度调整采用行星齿轮减速机。最后增加了测速机构。本圆盘剪切机可普遍用于横切机组、酸洗机组等。关键词：圆盘剪切机，带钢，压下装置，强度校核The disc alligator shears design AbstractThe industry of various countries develops rapidly now, the steel, as the main pillar of industry, its development can reflect the national strength to a great extent. Modern steel metallurgy industry one starting point that develop in to processing speeds. Disc shears is an important equipment among them.Disc shear machine set up in finishing production line. It usually uses to cutting neat the movement steel plate longitudinal edge and cut the strip into narrow one. It can be divided into two kinds according to its use: disc shears of cut stencil plates side and disc shears of cut strip.The disc shears design calculation is taken in makes the massive investigation to the ANSHAN steel group Cold-rolling mill 1700 transverse cutting aircrew as the background. We have thorough understanding to the disc shears and the correlation equipment. We had very designed to the main transmission system, depress the system and gap adjustment organization, we are carry on these designs from the materials mechanics angle, dynamics and economic. The main content including electrical machinery selection, Axis and gear design, Implementing agency design and so on, and the same time, we make the optimized improvement and the intensity examination to the major parts. This design improvement spot: First, in radial clearance adjusting mechanism link motion gear, second, backlash adjustment increase self-locking installment. Third, the width control uses the planet gear speed reducer. Finally increased has measured the fast organization. This disc shears may use in the transverse cutting unit, the acid pickling unit generally and so on.Key words: Disc shear, strip, depress the system, the intensity examination目 录1.绪论11.1选题的背景和目的11.2 圆盘式剪切机国内外的发展现状11.3 圆盘剪切机研究的内容和方法31.3.1圆盘剪切机在机组的布置和作用31.3.2 圆盘剪切机的类型和特点51.3.3 圆盘剪切机设计内容和方法52. 设计方案的选择和方案评述63. 电机容量的计算83.1 定性选电机83.2 选择电动机的容量83.3 确定转速113.4 电动机的校核124. 主要零件强度计算校核144.1 齿轮的计算与校核144.1.1齿轮的计算144.1.2 按接触疲劳强度校核144.1.3 按弯曲疲劳强度校核184.2 传动轴的强度校核计算204.2.1轴的材料及其机械性能204.2.2 轴的模型及传递功率的确定204.2.3 按弯扭合成进行轴的强度校核214.2.4 按疲劳强度进行精确校核244.3 轴承的选取及校核284.3.1 根据工作条件选取轴承类型284.3.2根据轴承结构确定轴承的型号284.3.3轴承的寿命校核284.3.4 验算轴承的极限转速314.4.2 键的尺寸的选择314.4.3键的强度校核315. 联轴器的选择335.1联轴器的分类335.2联轴器的选择335.3联轴器的强度计算336. 系统的润滑356.1润滑剂的种类356.2润滑方式的选择356.3润滑方式的
