800大型轧机设计 摘要 随着近年钢铁工业的飞速发展，型钢市场的需求量也越来越大，对质量的要求也是越来越高。因此，我们对型钢轧机进行相应的设计与改进，以提高产量和质量来满足生产及客户的要求。 本次设计对800型钢轧机进行了相应的改进与校核。 首先论述了型钢轧机的背景与发展状况，型钢轧机的类型、特点、用途及生产工艺流程。然后，对型钢轧机进行了总体的方案评述，800大型轧钢机为轨梁式三辊型钢轧机。采用横列式布置，三重式轧钢机采用集中驱动，上中下三个轧辊旋转方向不变，为单向不可逆式传动。因为换辊的次数比较多，通常采用开口式机架。电动机采用直流可调电动机，无减速器，通过齿轮座带动轧辊转动。齿轮座采用人字齿轮，电动机与齿轮座之间采用齿形联轴器联接。各机座间采用梅花联接轴联接，而与齿轮轴端采用滑块式万向接轴。还对安全接手进行了改进，将原来的安全销改为安全环。在随后的几章中进行了主电动机容量的选择、主要零件的计算、润滑方式的选择。 关键词：型钢轧机，横列式，安全环 800 large rolling mill design Abstract With the rapid development of the steel industry in recent year, That the deficit is growing market demand for quality is increasing. therefore ,we corresponding to payments rolling mill design and improved in order to increase productivity and quality to meet production and customer requirements. The current design of the 800 payments rolling mill with a corresponding improvement in accuracy. First discussed the background and development payments of rolling mill, rolling mill of deficit types, characteristics, uses and production processes. Then, on the overall deficit rolling mill programmes comments 800 large rolling mill in orbit Liang-3 roller payments rolling mill. Used across a layout, triple-rolling mill driven by focused, on the direction of the next three roller-unchanged for one-way transmission is not reversible style. Because the number of more-roller, normally used openings style racks. Electric motors using direct current powers electric motors, no reducer through Block-roller wheels turning. Block, who used the word gear wheel, electric motors and gears used chixing shaft coupling between Block connectivity. Block of the plane connectivity between a plum link axle, and gear type universal huakuai used to axle. Also took over the security improvements will be part of the original security sales to security. In the ensuing chapters, the main electric motors capacity choices, the main components of computing, provide lubrication options. Keyword : finances rolling mill, row type,
