1、有全套图纸QQ1074765680800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
2、。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800largerollingmilldesign有全套图纸QQ1074765680有全套图纸QQ1074765680Abstract
