矿用U型钢成型修复机整体设计

本科毕业设计（论文）题目矿用U型钢成型修复机整体设计院（系部）万方科技学院专业名称机械设计制造及其自动化年级班级07级机制2班学生姓名冯柳清指导教师明平美2011年6月10日摘要本设计是关于矿用U型钢支架滚压成型修复机的设计，通过对比各种滚弯成型原理，最终确定利用侧辊摆动式四辊滚弯成型原理，主要对主副辊及减速器部分进行了较为详细的设计计算。首先对各种滚弯成型原理进行了分析比较，选定类型，然后对各辊（主要是主副辊）进行分析设计。侧辊摆动式四辊滚弯成型原理是由主副辊对滚，为滚弯U型钢提供动力，能够连续滚弯，经济高效。设计中的减速器是三级展开式圆柱齿轮减速器。齿轮材料为40Cr（调质），校核齿轮、轴、键、轴承确保实际可行。关键词：U型钢四辊修复机减速器齿轮ABSTRACTThisdesignisaboutthemachinethatstentsrollformingrepairUshapedsteel.Aftercomparingvariousprinciples,Ifinallydeterminationusingthesiderollerswingfourrollbendingformingprinciple.Inthedesign，Ididadetailedcalculationfortherollergears.Firstofall，Icomparedvariousprinciplesofrollbendingandselectedthetypes,thenIdesignthemainlyanalyzesmainandviceroller.Siderollerswingfourrollsbendingformingprinciplebylordtoroll.VicerollertorollbendingUsectionsprovidemotivationforcontinuousrolling,curved,economicefficiency.Thelastpartofthepaperisaboutdeceleratorwhichischoosingtripleexpandingcolumngearconstruction.Thematerialofgearis40Cr（hardening）.Thegears，axes，bearingsarechecked，sotoconfirmthisdesignthisdesignispractical.Keywords：UshapedsteelFourrollsRepairmachineDeceleratorGear目录绪论....................................................................................................-1-1.1概述.................................................................................................-1-1.2卷板机的原理.................................................................................-2-1.2.1卷板机的运动形式..................................................................-2-1.2.2弯曲成形的加工方式..............................................................-3-1.3卷板机的发展趋势.........................................................................-4-第二章方案的论证及确定..................................................................-6-2.1方案的论证.....................................................................................-6-2.1.1方案1双辊卷板机.................................................................-6-2.1.2方案2三辊卷板机.................................................................-7-2.1.3方案3四棍卷板机.................................................................-8-2.2方案的确定.....................................................................................-9-2.3本章小结.........................................................................................-9-第三章侧辊摆动方案的确定............................................................-10-3.1u型钢滚弯加工的步骤和过程.....................................................-10-3.2主传动方案的机构设计...............................................................-11-3.2.1主传动达到的技术指标........................................................-11-3.2.2主传动设计方案....................................................................-11-3.3控制系统方案选择..............................................错误!未定义书签。3.4液压系统的传动原理..........................................错误!未定义书签。3.5本章小结..............................................................错误!未定义书签。第四章传动设计.......................................................错误!未定义书签。4.1传动方案分析......................................................错误!未定义书签。4.1.1齿轮传动.......................................................错误!未定义书签。4.1.2皮带传动.......................................................错误!未定义书签。4.2传动系统的确定..................................................错误!未定义书签。4.3本章小结..............................................................错误!未定义书签。第五章动力设计.......................................................错误!未定义书签。5.1主传动系统液压马达的选择..............................错误!未定义书签。5.1.1主副辊参数的选择计算...............................错误!未定义书签。5.1.2液压马达的功率确定..................................错误!未定义书签。第六章减速器设计...................................................错误!未定义书签。6.1传动方案拟定......................................................错误!未定义书签。6.2减速器总传动比及其分配..................................错误!未定义书签。6.2.1总传动比.......................................................错误!未定义书签。6.2.2传动比的分配...............................................错误!未定义书签。6.3各轴参数计算......................................................错误!未定义书签。6.3.1各轴转速计算...............................................错误!未定义书签。6.3.2各轴扭矩计算...............................................错误!未定义书签。6.3.3各轴功率计算...............................................错误!未定义书签。6.4齿轮传动设计......................................................错误!未定义书签。6.4.1一级变速齿轮设计.......................................错误!未定义书签。6.4.2二级变速齿轮设计................................................................-13-6.4.3三级变速齿轮设计................................................................-16-6.4.4齿轮设计结果汇总................................................................-20-6.5轴的设计校核...............................................................................-21-6.5.1轴的结构设计........................................................................-21-6.6轴承的选型...................................................................................-23-6.7键的选型及校核...........................................................................-23-6.8减速器的结构设计和齿轮、轴承的润滑...................................-25-6.8.1箱体参数.................................................
