毕 业 设 计 二级齿轮减速器设计说明书 摘要 本次毕业设计主要利用三维虚拟设计软件Pro/Engineer对400T冷剪机的减速器部分进行三维参数化设计，所做主要工作主要包括：参与完成400T冷剪机总体方案的论证及主要零部件的选型设计；完成二级减速器的选型及总体设计；完成电机、齿轮及轴的校核及计算；完成相关零部件（齿轮、轴）的有限元分析及三维参数化造型和装配。 对400T冷剪机的减速器进行了设计，在设计中：首先,阐述了冷剪机在轧钢生产线中的重要作用，在此基础上提出了400T冷剪机中减速器部分的三维参数化设计课题；其次，分析冷剪机的工作原理，进一步对其中的传动装置进行初步设计及校核，并且利用 ANSYS软件Abstract The main advantage of graduate design three-dimensional virtual design software Pro / Engineer on the 400T part reducer of cold shear three-dimensional parametric design, done by the main work includes: participation in the completion of the overall program 400T cold shearing machine argument and the main components Type Design; completed two reducer selection and design; complete motor, gears and shafts checking and calculation; complete the relevant parts (gears, shafts) and three-dimensional finite element analysis of parametric modeling and assembly. 400T cold cutting machine on the reducer has been designed, in the design: First, set the cold shear rolling production line in an important role in this proposed based on the 400T cold scissors reducer part of three-dimensional parametric design subject; Second, analysis of the working principle of the cold shear, which drives further preliminary design and verification, and the use of ANSYS software and the gear reducer shaft in a simple finite element analysis; Finally, PRO / E Engineering software, set up important parts reducer 3D model as a basis for the completion of the relevant parts of the virtual assembly. Key words: cold shear, reducer, 3D parametric design, finite element analysis 目 录 摘要 Ⅰ Abstract Ⅱ 第1章 绪论 1 1.1 冷剪机在冶金工业生产中的主要作用和应用 1 1.2 我国机械制造技术的发展状况和先进技术的特点 1 1.2.1 我国制造业的发展与差距 1 1.2.2　先进制造技术的特点 2 1.3 课题的提出、任务及关键技术 2 1.3.1 课题的提出 2 1.3.2任务要求 3 1.3.3关键技术 3 1.4设计成果 3 第2章 总体方案的拟定 4 2.1 冷剪机的主要结构及工作原理 4 2.2 冷剪机主要部件的选型设计 4 2.2.1 皮带张紧装置 4 2.2.2安全保护装置 5 2.2.3棒材压紧装置 5 2.2.4快速换刀装置 5 2.2.5 减速器系统 5 2.3工作机器特征的分析 5 2.4 剪切机设计考虑的问题 5 第3
