PC轧机换辊小车设计论文[带图纸].doc

辽宁科技大学本科生毕业设计(论文)第I页PC轧机换辊小车设计摘要本文叙述了鞍钢2150热轧板带钢生产线精轧机换辊小车的设计情况,辊系小车的驱动方式原为链条拖动和液压缸驱动的棘轮机构共同作用,步骤烦琐,换辊时间长,改为动力小车直接驱动后,缩短了换辊时间,提高生产效率。本文概述了换辊小车的国内外发展情况及其发展方向。主要进行PC轧机换辊小车的设计。利用电机提供动力,使减速器输出轴上的链轮在固定链条上滚动,从而使小车在轨道上运动。利用液压缸使拉出钩绕销轴转动,进行挂钩或推钩,从而使工作辊拉出或推进。最终实现换辊工作。在设计过程中进行了换辊小车的传动方案、工作原理、润滑及环保与经济性分析,重点进行换辊小车的结构设计、工作参数的选择、电动机的选择及计算,设计中主要零部件的计算及校核。在参阅相关资料并借鉴前人经验的基础上,通过对换辊小车的设计及分析,各项技术均满足要求,本设计具有一定的实际应用价值。关键词换辊辊系小车链条棘轮机构动力小车辽宁科技大学本科生毕业设计(论文)第II页PCrollermillforcardesignABSTRACTInthispaper,therollingcardesignoffinishingmillonAnshansteel2150hotrolledstripsteelplateproductionlinewaspresented.Accordingoriginaldesigned,rollchangingcarwasmovedbyachainsystemandaratchetsystem.Theprocesswastoocomplicatedanditspendsalotoftimeonrollerchanging.Afteritwasredesigned,rollerchangingtimewasshortenedandefficiencywashighlyimproved.Thispaperoutlinesthedevelopmentofdomesticandinternationalsituationoftherollingcaranditsdevelopmentdirection.ImainlydesignedrollingcarforPCmainrollermill.Itusedmotortoprovideelectricalpowersothatsprocketontheoutputshaftofreducercanrollonthesprocketfixedchain.Sorollingcarcouldmovealongtheorbit.Ituseshydrauliccylinderstopullhookaroundthepinrotation,orpushorpullhook,sothatpulledoutorpushintheworkroll.Rollerschangedworkcouldbeeventuallyrealized.Intheprocessofdesigningacar,thedrivenschemedesign,workingprinciplestatement,lubricationandenvironmentalprotectionandeconomicanalysishavebeendone.Thepapermainlyfocusesonthestructuraldesignofcar,thechoiceofmotorandworkingparameters,thecalculationandverificationofthemaincomponents.Onthebasisofconsultingtherelevantmaterialsandusingforefathersexperienceforreference,throughthedesignandanalysisofrollingcar,everyindicatorsreachesthedemands,thisdesignhasacertainvalueinactualusing.KEYWORDSRollchangingCarofrollsetChainRatchetsystemDrivingcar辽宁科技大学本科生毕业设计(论文)第III页目录摘要.............................................................................................................IABSTRACT...............................................................................................II1绪论.......................................................................................................11.1换辊小车的概述................................................................................................11.1.1换辊小车的用途............................................11.1.2换辊小车的类型............................................11.1.3换辊小车的动力结构........................................21.2国内外对换辊小车的研究................................................................................21.3课题的背景及意义............................................................................................51.4本文主要研究工作............................................................................................52总体方案设计与选择............................................................................72.1换辊小车的驱动方案设计与选择.....................................................................72.1.1传动方案设计..............................................72.1.2电机的选择................................................72.2链轮与液压缸的选择.........................................................................................82.2.1链轮的选择................................................82.2.2液压缸的选择..............................................83传动系统的设计计算............................................................................93.1原始数据.............................................................................................................93.2换辊小车所需驱动力计算.................................................................................93.3电机的选择.........................................................................................................93.3.1选择电机的结构形式........................................93.3.2选择电机的容量...........................................103.3.3电机的校核...............................................11辽宁科技大学本科生毕业设计(论文)第IV页3.4确定传动装置的总传动比和分配传动比.......................................................113.4.1传动装置总传动比.........................................113.4.2分配减速器的各级传动比...................................123.4.3各轴的运动和动力参数.....................................124主要零部件的选择、设计和校核.......................................................144.1蜗轮蜗杆的设计与校核..................................................................................144.1.1选择蜗杆传动类型.........................................144.1.2选择材料.................................................144.1.3按齿面接触疲劳强度进行设计...............................144.1.4蜗杆与蜗轮主要几何尺寸计算...............................164.2齿轮的设计与校核一...................................................................................184.2.1选定齿轮类型、精度等级、材料及齿数.......................184.2.2按齿面接触强度设计.......................................184.2.3按齿根弯曲强度设计.......................................214.2.4.几何尺寸计算............................................224.3齿轮的设计与校核二...................................................................................234.3.1选定齿轮类型、精度等级、材料及齿数.......................234.3.2按齿面接触强度设计.......................................244.3.3按齿根弯曲强度设计..........
