1700立辊轧机主传动系统设计
摘要
立辊轧机曾经一度被人们所忽视，然而随着近年来轧钢技术的不断进步，各种新方法的应用，立辊轧机相对于以往有了很大的改进，它在轧钢生产中使用越来越广泛，尤其是在热轧薄板带钢生产中的破鳞、控制板坯宽度等方面更是必不可少的轧钢设备。本次设计的主要目的是对立辊轧机的主传动系统进行了解和研究，并对主要部件进行设计和校核计算，最终设计绘制出立辊轧机主传动系统的总装配图。在查阅文献和相关资料的同时，通过到鞍山钢铁集团公司热轧带钢厂1700及1780生产线进行参观实习，使我对立辊轧机有了深入的了解和认识。本次设计主要包括阐述立辊轧机的发展、结构、作用和主传动方案等，并重点对立辊轧机主传动系统中涉及的各个零部件进行了设计计算。主要包括轧机结构参数计算、力能参数计算、主电机选择、减速箱中齿轮传动设计、轧辊设计与校核、轧辊轴承寿命计算等相关内容。

The Design of Edger Mill Main’s Driving System
Abstract
The Edger mill were once ignored by many people，however，they have a very great improvement which compared to the past as the technique of rolling steel progressing incessantly and the application of kinds of new methods in recent years. They have been used more and more extensively in production of rolling steel. They are more essential rolling steel equipment especially in such aspects as breaking scale, controlling the width of the panel in hot-rolled sheet metal and belted steel production. The main purpose of the design is to have a further understanding to the Edger mill’s main driving system and to have a check and calculation to the main parts，and eventually to design the assembly drawing of the Edger mill’s main driving system. While consulting a large number of documents and referring to relevant knowledge, and through visiting the 1700 and 1780 rolling steel production lines in Hot Rolling mill of An Shan’s Iron and Steel Company，I have a great improvement in rising to perceptual knowledge from rational knowledge.The design mainly includes the development, the structure and functions of the Edger mill and the scheme of the Edger mill’s main driving system. At the same time I have checked and calculated all parts related to the main driving system which insists of mill structural parameters, force and energy parameters, the main motor choice, speed gear box design, Design and Verification roller, roller bearings and other related content.
