机械毕业设计（论文）-1500六辊冷连轧机主传动系统设计全套图纸】1500六辊冷连轧机主传动系统设计摘要随着工业生产的迅猛发展，我国对板带材的需求日益增加，特别是高精度冷轧薄板的生产更是供不应求，本次设计的是1500六辊冷连轧机组主传动系统，设计的该轧机能轧的最小板坯厚度达到了0.3mm，本次设计的主要思路是根据轧件原始尺寸和成品尺寸，确定轧制压下规程，从而计算轧制力和轧制力拒，选择电机，进而确定工作辊、中间辊、支承辊尺寸，并分别进行扭转、接触应力、弯曲强度校核，并对机架、联轴器进行了结构和强度计算，采用了初选结构、校核强度、校核通过则采用，不通过则再选，再校核，直到校核通过为止的基本机械设计方法。这不仅是对所学的理论知识的综合运用，也是考验思维的严谨缜密。此外，还对设备的安装、试车、经济性分析以及冷轧机的选题背景、发展历史做了简单的介绍，在设计中根据生产实际的要求，选择了不同的设计方案实现主传动，经过比较，确定了最佳方案，对方案中的各重要部件进行结构和性能的校核，力求达到最合理的设计，满足生产的设计要求。由于该题目是一个全新的课题，所以在设计中遇到了很多的问难，即使尽了最大的努力，得到老师、师傅的很大帮助，也难免有很多错误和考虑不全面的地方，希望大家批评指正。关键词：1500六辊冷连轧机组，轧制力，轧制力矩，联轴器，机架全套图纸，加1538937061500sixrollercoldmillmaindrivesystemofthedesignunitAbstractWiththerapiddevelopmentofindustrialproduction,China'splatestripincreasingdemand,especiallyintheproductionofhighprecisioncold-rolledsheetisinshortsupply,thisdesignis1,500unitsofsixrollercoldmillmaindrivesystem,designoftherollingmilltoachievetheminimumslabthicknessof0.3mm,themainideaofthedesignisbasedonrollsizeandfinishedpiecesoforiginalsize,determinetherollingdownoforderinordertoestimatetherollingforceandrollingforceresist,selectmotor,todeterminetheworkroll,intermediateroller,rollerbearingsize,andwerereversed,contactstress,bendingstrengthchecking,andrack,couplingtothestructureandstrengthcalculation,usingtheprimarystructure,checkingthestrength,Checkingthroughtheuseof,doesnotpassthere-election,re-checkuntilthecheckthroughthedateofthebasicmechanicaldesign.Thisisnotonlyatheoryfortheintegrateduseofknowledge,butalsothetestofcoherentthinkingInaddition,theequipmentinstallation,testing,analysisofeconomictopics,aswellasthebackgroundofthecoldrollingmill,abriefhistoryofthedevelopmentoftheintroduction,inthedesigninaccordancewiththerequirementsoftheactualproduction,selectadifferentdesignoptionstoachievethemaindrive,aftercomparisontodeterminethebestprograminthemajorstructuralcomponentsofthecalibrationandperformance,andstrivetoachievethemostreasonabledesign,productiontomeetthedesignrequirements.Sincethetopicisanewsubject,encounteredinthedesignofalotofdifficultquestions,eventhebesteffortstobeateacher,masterofgreathelp,itisinevitablethatmanyerrorsanddoesnotconsiderthelocalcomprehensive,Ihopeallcriticism.Keywords:1500sixrollercoldrollingunit;Rollingforce;Rollingmoment;Coupling;Rack目录1、绪论.............................................................................11.1选题背景及目的.......................................................11.2冷轧机发展............................................................11.3板型控制...............................................................21.4研究内容和研究方法.................................................32、传动方案评述与选择.........................................................42.1方案选择...............................................................42.2方案评述...............................................................42.3电机选择...............................................................52.4.联接轴选择............................................................53、力能参数的计算...............................................................63.1轧制力的计算..........................................................63.1.1轧制规程........................................................63.1.2初选轧辊材料...................................................73.1.3轧辊主要参数的确定............................................73.1.4轧制力的计算.................................................93.2轧制力矩的计算.....................................................123.2.1轧制力矩的计算...........................................123.2.2反力矩的计算...............................................133.2.3摩擦力矩的计算.............................................144、主电机容量的选择..........................................................154.1初选电机功率........................................................154.2轧机主电动机力矩..................................................154.3各轧制阶段时间计算...............................................174.3电机的校核..........................................................195、轧辊强度校核................................................................205.1工作辊强度校核.....................................................205.2支承辊强度校核.....................................................215.3工作辊与中间辊间的接触应力校核..............................236、机架的设计校核.............................................................266.1机架结构参数选择..................................................266.2机架的强度计算.....................................................277、联接轴计算..................................................................337.1万向接轴的结构尺寸...............................................337.2接轴叉头应力计算..................................................337.3接轴扁头应力计算..................................................347.4接轴轴体的应力计算...............................................348、安装、试车规程制定.......................................................358.1设备的安装..........................................................358.2设备的试车规程.....................................................368.2.1试运转前的准备..............................................368.2.2试车步骤......................................................368
