编号无锡太湖学院毕业设计(论文)题目箱式电炉进出料机设计信机系机械工程及自动化专业学号学生姓名指导教师(职称副教授)2013年5月25日无锡太湖学院本科毕业设计(论文)诚信承诺书本人郑重声明所呈交的毕业设计(论文)箱式电炉进出料机设计是本人在导师的指导下独立进行研究所取得的成果,其内容除了在毕业设计(论文)中特别加以标注引用,表示致谢的内容外,本毕业设计(论文)不包含任何其他个人、集体已发表或撰写的成果作品。班级机械96学号0923257作者姓名2013年5月25日III摘要75kW和95kW箱式电炉是热处理专业厂及一般中型机械厂目前最常使用的热处理加热设备。过去传统的装出炉方法都是操作,采用手工将工件送入炉膛热处理后再由炉内取出。由于箱式电炉炉膛深,且工件只能在水平方向进出炉门,小工件随手甩进,大工件抬至路口用撬棒等推入炉门,劳动强度很大。为此,我们在毕业设计前提出了有关该课题的设计,该机使用于批量生产的机械零件热处理加热时的进出料,特别适用于RJX759和RJX959型等炉膛较深的箱式电炉加热大件时的进出料,也可用于炉膛尺寸与上述箱式电炉相近的燃料炉。经系列化后也可用于其他型号的箱式炉。箱式电炉进出料机的整机外形为一密封型小车,由电器控制系统、行走动力系统、推拉传动系统、推拉机构、机架、电磁止退系统等部分组成,此外还配有配套件地面导轨、炉内导轨及燃料等。其中电器控制部件全部装在小车体内,仅有控制按钮盒在体外作远距离控制之用。关键词箱式电炉进出料机推拉机构IVABSTRACT75and95dyadickwboxelectricfurnacesarethattheheattreatmentthattheheattreatmentspecialfieldfactoryandingeneralmediumsizedmachineryworksuseatpresentmostoftenprocessesequipment.Thattraditiondressgoingoverputsupstovemethodallistoadoptmanualoperation,theinnertakesoutagainfromthestoveaftersendingworkpieceinfurnacechamberheattreatment.Theelectricfurnacefurnacechamberisdeepsincetheboxisdyadic,workpiececanonlypassinandoutofafurnacegateinleveldirectionand,minorworkpieceisflunghandilymovingforward,bigworkpieceraisetillthecrossingusescrowbartowaittopushenteringafurnacegate,laborintensityisverybig.Forthispurpose,wehavebroughtforwarddesignaboutthatproblemingraduationpracticeprelude,theturnoverthatmachineuseswhenheattreatmentheatsinthemachinerypartsmassproducinghasexpectedthat,theturnoverapplyingtoelectricfurnacesoffurnacechambermoredyadicthandeepboxsuchasRJX759andRJX959typespeciallywhenheatingdurablehouseholdapplianceshasexpectedthat,alsomaybeusedforclosetoabovementioneddyadicboxelectricfurnacefurnacechamberdimensionfuelstove.InthedayaftertomorrowthetypeboxisalsoYongYuotherdyadicasaresultofbeingseriatedstove.Dyadicboxelectricfurnaceturnoverexpectsthatthemachinecompletemachineexternalformsealsoffthetypehandcartforone,drivingforcesystem,pushandpulldrivesystem,pushandpullorganization,chassis,electromagnetismcontrollingsystem,goingonfootfromelectricalequipmentstopreturningsystemwaitingforpartmadeupof,besidesbequalifiedforhavepartsandauxiliaryequipmentfloorslideway,stoveinnerslidewayandfueletc.Alldressofelectricalequipmentfunctionunitsamongthemexperiencesandobservesaninnerinthehandcart,hastheunderthecontrolofbuttonboxtocontrolthatinextracorporealdistantworkdistanceusingonly.KeywordsDyadicelectricfurnaceofboxMachinepassinginandoutofmaterialPushandpullorganizationV目录摘要.............................................................................................................................................IIIABSTRACT..................................................................................................................................IV目录.................................................................................................................................................V1绪论.............................................................................................................................................12设计方案的确定.........................................................................................................................32.1主要结构【1】......................................................................................................................32.2工作过程...........................................................................................................................32.3主要性能指标...................................................................................................................33传动机构的设计与计算.............................................................................................................53.1锥齿轮的设计1234579.........................................................................................53.2锥齿轮轴的设计...............................................................................................................93.2.1轴上零件的固定123812.................................................................................93.2.2花键的设计12312...........................................................................................103.2.3轴承的选择123481012..............................................................................103.2.4轴的强度计算23...............................................................................................123.2.5轴的刚度计算23................................................................................................143.3传动轴的设计.................................................................................................................143.3.1轴上零件的固定1114.........................................................................................143.3.2花键的校核4........................................................................................................143.3.3轴承的校核4........................................................................................................143.3.4轴的强度计算23................................................................................................163.3.5轴的刚度计算23................
