七辊中板预矫正机主传动系统的设计 摘要 在钢铁产品的实际生产上，中厚板得到了飞速度发展，随着社会市场的需求不断增大，中厚板矫直机的技术水平也成为了衡量一个国家钢铁工业装备水平的一个重要标志之一。同时随着我国钢铁工业的发展，对中厚板的数量和矫直技术也提出来更高的要求中厚板（它的厚度一般不小于4.0mm）在建筑业，机械制造业，造船业等等得到了广泛应用。本篇论文中，首先论述了矫正机的背景与发展状况，以及未来的发展趋势，并根据当前实际情况，考虑经济性和效率性等相关因素，对相关设备做了合理选用；然后对本次设计的中厚板矫正机进行了方案的选择与论述；其次确定了矫正机相关参数，并通过对矫正力、矫正力矩和主电机功率的计算及工作特点选择矫正机的电机类型和型号；最后，对矫正机的主要零部件（第三个工作辊、工作辊轴承）进行了校核计算。说明书的最后还对润滑的选择和设备的环保、可靠性和经济可行性做了论述。 关键词：中板矫正机；主传动系统；矫正辊 The Predistortion Seven Roller Plate Design Of Main Drive System Abstract The actual production of steel products, plate has been flying speed development, with the growing needs of the community market, technology plate leveler has become an important indicator to measure a countrys iron and steel industry equipment level one. Meanwhile, with the development of Chinas steel industry, the plate number and straightening technology also raised higher demands plate (which typically have a thickness greater than 4.0mm) in the construction industry, machinery manufacturing, shipbuilding, etc. It has been widely used. In this thesis. Background, development status and trend of straightening machine were firstly discussed and according to the present situation, considering economy and efficiency-related factors, I select some related equipment reasonably and then this design plate correction machine selection and discussed solutions. Second, determine the correct machine parameters, And through the force of correction, the correction torque and motor power of computing and work characteristics select straightening machine motor types and models. Finally, the main parts of straightening machine (the third work rolls, work roll bearings) were checking calculation. The specification for environmental protection and lubrication equipment selection, reliability and economic feasibility of doing discussed Key words: Plate straightening machine；Main drive system；Straightening roller 目录 摘要 I Abstract II 1 绪论 1 1.1 课题研究的目的及意义 1 1.2 国内外发展的现状和趋势 1 1.3 矫直机的工作原理 2 1
