毕业设计（论文）-1400㎜连退机组卷取机传动系统设计计算.doc

武汉科技大学本科毕业论文摘要钢铁工业是和综合国力的重要标志, 钢铁发展直接影响着与其相关的国防工业及建筑、机械、造船、汽车、家电等行业。轧钢机械的设计是钢铁生产中的一个最重要的环节,近年来,热轧和冷轧技术日趋完善, 特别是冷轧技术,代表着钢铁行业的前沿技术,在世界各地迅速发展,我相比差距还很大。推进我国钢铁行业的发展,是当代大学生特别是我们机械专业的大学生义不容辞的责任。传动机构的设计主要包括传动方案分析选择,电动机的设计选择,二级斜齿传动齿轮的计算和校核,轴的设计校核,轴承的选择和校核,轴上键的选择校核,以及减速箱箱体的结构设计等,在设计过程中要综合运用以前所学的机械设计、机械原理、材料力学等专业知识,进行经验估算和数据处理,把所学的专业理论知识和实践结合起来。传动系统设计要首先考虑开卷机的综合性能,传动的合理性是开卷机正常工作的前提,也是轧钢产品的质量保障。毕业设计是对所学知识的综合应用,可以达到具备对各种常用的通用机械零部件的设计和选用的能力,进而达到独立设计简单机械的能力。关键词:齿轮; 轴; 轴承; 键武汉科技大学本科毕业论文 Abstract Iron and steel industry is an important foundation for national industries , is the level of the national economy and an important indicator of overall national strength , iron and steel development associated with a direct impact on the defense industry and construction, machinery, shipbuilding, automobiles, home appliances, etc 。 The design of rolling mill machinery isone of the most important aspect of steel production 。 In recent years , hot-rolled and cold-rolling technology are maturing , cold-rolling technology in particular, represents the cutting-edge technology of iron and steel industry , The rapid development around the world , although China's achievements must be made , however, compared with the gap between the world's advanced level is still very great 。 Promote the development of China's steel industry is the contemporary college students, especially college students, we machinery duty-bound to professional responsibility. The design of transmission include transmission analysis of choice , motor selection, helical Gear II calculation and check, check-axis design, bearing selection and verification, the choice of key axis calibration, as well as the slowdown in the structural design of boxes, etc 。 The design process to study the integrated use of the previous mechanical design, mechanical principles of mechanics of materials, such as expertise,empirical estimation and data processing,to study the theoretical knowledge
