摘 要 PAGE   PAGE \* MERGEFORMAT I 摘 要 现代板生产工艺在四辊可逆轧机中成为主要的机型，其工作原理是使工件通过2个相对旋转的轧辊产生加工压力，产生塑性变形。针对现有济钢和首钢3500中厚板轧机，通过辊系的微尺度等效杆系分析，消除普通四辊轧机暴露出的一些弊端，设计较高性能的四辊可逆式3500轧机；选择计算轧机的力能参数，设计轧机结构，计算主要结构参数。 本次设计对四辊可逆轧机主传动系统进行设计分析，研究，计算，阐述了板轧机的历史发展以及国内外轧机的发展，确定坯料、轧制特点、主传动机构的组成、机架形式、轧制速度、轧辊的结构特点、轴承形式、润滑形式及经济性和环保性。首先对主传动系统力能参数进行了计算，包括轧制力、轧制力矩和主电机功率的计算及校核，其次是主要零件强度的计算，如轧辊、轴、轴承、机架。然后对系统的润滑进行分析和讨论并对本次设计中的经济性和环保性进行了详细的分析和论述。最后进行了数据的整合。 关键词 中厚板；闭式机架；轧辊；轧制力 Abstract Abstract  PAGE \* MERGEFORMAT II Abstract Modern plate production technology in four roller reversible rolling mill become the main models, the working principle is to make the workpiece through the 2 relative rotation of the roller to produce processing pressure, produce plastic deformation. In view of the existing Jinan Iron and steel and Shougang 3500 plate mill, through and micro scale equivalent linkage analysis, eliminate the common four rollers mill exposed some drawbacks, design high performance of four roller reversible of 3500 mill; selection and calculation of rolling force and energy parameters, design the structure of the rolling mill, main structure parameters. The design of four high reversible rolling mill main drive system design and analysis, study, calculation, expounds the plate mill of historical development and rolling mill at home and abroad development, determine the structural characteristics of blank, rolling characteristics, the main transmission mechanism composition, mount, rolling speed, roll, bearing, lubrication form and the economy and environmental protection. First, the main drive system parameters were calculated, including rolling force, rolling torque and the main motor power calculation and check, followed by the main parts of the calculation of strength, such as roll, shaft, bearing, rack. Then the lubrication of the system is analyzed and discussed, and the economic and environmental protection in this design are analyzed and discussed in detail. Finally, the integration
