2150粗轧机主传动设计毕业论文.doc

2150粗轧机主传动设计 摘 要 此次毕业设计的设计对象是2150粗轧机主传动系统。轧机是将钢锭及连续铸坯轧制成材的生产环节。用轧制的方法生产钢材，具有生产率高、品种多、生产过程连续性强、易于实现自动化等优点。因此轧机得到广泛的应用,约有90﹪的钢都是经过轧制成材的。轧机设备的好坏对轧钢厂的效益有很大的影响，而且轧钢产业在整个国民经济中占据着异常重要的地位。这些同时说明了本次设计的必要性和重要性，并且设计本身也是对我们的所学起到检验作用。设计内容包括传动方案的选择，轧制力计算及主电机容量的选择，验算轧辊稳定性，工作辊和支撑辊的设计及强度校核，轧辊轴承的选择，万向连接轴的选择计算，润滑方法的选择，环保性及经济分析。设计结论得出此次设计的轧机主传动系统有较好的调速性能、较宽的调速范围、响应速度快、轧制质量高、传动平稳、润滑条件好、噪音低、使用寿命长等优点，各零部件也满足条件，完全达到了设计要求。 关键词：主传动；粗轧机；可逆轧制；工作辊；支承辊 2150 Roughing Mill Main Drive Design Abstract The graduation project is a 2150 design objects roughing mill main drive system. Mill is rolling ingot and continuous slab lumber production processes. Produced by rolling steel, high productivity, variety, continuity of the production process, easy to realize the advantages of automation. So the mill is widely used, about 90% of the steel is rolled through veteran. The quality of mill equipment has a great impact on the effectiveness of the rolling mill and rolling mill industry occupies an extremely important position in the national economy. These also describes the necessity and importance of this design, and the design itself is also learned to play our role in testing. Design includes selection, rolling force calculation and the main motor capacity transmission scheme selection, checking roll stability, design work roll and backup roll and strength check, roller bearing selection, choose the connection shaft universal calculation, lubrication selection methods, environmental protection and economic analysis. Design The design of the conclusions mill main drive system has better speed performance, wide speed range, fast response, high-rolling quality, smooth transmission, good lubrication conditions, low noise, and long life advantages, but also to meet the conditions of the parts, fully meet the design requirements. Keyword:The main drive; Roughing mill; Reversible rolling; Work roll; Supporting rollers 目 录 1 绪论 1 1.1选题背景及目的 1 1.2轧钢机械国内外发展概况 1 1.3设计的主要内容和方法 3 2 总体方案设计 4 2.1概述 4 2.2方案比较 4 2.3方案
