本科毕业设计（论文）I分类号单位代码密级公开学号学生毕业设计（论文）题目基于Pro/E的蜗轮蜗杆减速器的建模与仿真作者黄胜军院(系)能源工程学院专业机械设计制造及其自动化指导教师答辩日期2014年5月24日本科毕业设计（论文）II摘要减速器是一种用于低转速大转矩的传动设备，把电动机或内燃机的动力通过减速器上的输入轴上齿数少的齿轮与齿数大的齿轮啮合达到减速的目的。蜗轮蜗杆减速器主要用来传递空间相交两轴之间的动力，它具有传动比大、结构紧凑、不需要其他机构就能实现反行程自锁等优点，因此在生活中得到了广泛的应用。但是蜗轮蜗杆减速器普遍存在着机械效率过低、传动发热量大、精度不高等缺点。这也是当前国内外致力于研究的前沿课题。Pro/ENGINEER是一种集零件设计、曲面设计、产品装配于一体的3D建模仿真软件，广泛应用于汽车、造船、航天、电子模具等行业。本文主要研究的是蜗轮蜗杆减速器的传动特性，首先是蜗轮蜗杆减速器的设计、校核、以及结构设计；其次是基于Pro/E的零件图的建模以及蜗轮蜗杆减速器装配图、爆炸图的生成；最后利用Pro/E进行仿真，输出蜗轮蜗杆减速器中个构件的运行图像、技术参数等。关键词：蜗轮蜗杆；减速器；Pro/E；模型；仿真本科毕业设计（论文）IIIBasedonPro/EmodelingandsimulationofwormgearreducerABSTRACTReducerisakindofequipmentthatbeusedofdrivinginlowspeedandhightorque.Themotorpowerorinternalcombustionenginebymeansofinputshaftgearlittlewheelengageswithlargenumberofachievethegoalofreduction.wormgearandwormgearreducerismainlyusedtotransferbetweenaxisoftheintersectionofspacepower.Ithasalargetransmissionratioandcompactstructure.Intheotherhand,wormgearandwormgearreducerhastheadvantagesofthestrokeself-lockingthatneedn’totheragencies.Therefore,ithaswidelyusedinthelife.Buttherearewidespreadquestionswhichlowmechanicalefficiencywormgearandwormreducer,transmissioncalorificvalueandthehigheraccuracy.Thisisalsocommittedtotheforefrontofresearchtopicathomeandabroadatpresent.Pro/ENGINEERisacollectionofpartsdesign,surfacedesign,productassemblyintheintegrationof3Dmodelingandsimulationsoftware,widelyusedinautomobile,Shipbuildingaerospace,electronicmoldandotherindustries.Thispapermainlystudiestransmissioncharacteristicsofwormgearandwormreducer.Inthefirst,Idesignedthewormgearandwormreducerandcheckedthestrongeranddesignthestructure.ThesecondfirstisthepartdrawingbasedonPro/Emodelingandtheproductionofwormgearandwormreducerassemblydrawing,explosion.Intheend,IwillproductrunningimageandtechnicalparameteraboutwormgearandwormreducerbasedonPro/Esimulation.Keywords:wormgearandwormreducer;Pro/E;model;simulation本科毕业设计（论文）IV目录摘要.................................................................................................................................................IIABSTRACT....................................................................................................................................III1.绪论...............................................................................................................................................11.1课题研究的背景................................................................................................................11.2减速器的国内外研究现状................................................................................................11.3课题研究的目的和意义....................................................................................................21.4研究内容............................................................................................................................22.减速器传动装置的总体设计........................................................................................................52.1已知参数............................................................................................................................52.2传动装置总体设计............................................................................................................52.3传动零件的设计计算........................................................................................................62.3.1蜗轮蜗杆的传动设计.............................................................................................62.3.2蜗轮蜗杆的尺寸设计.............................................................................................73.蜗杆、蜗轮轴的基本尺寸设计..................................................................................................153.1蜗杆轴基本尺寸设计......................................................................................................153.2蜗轮轴的基本尺寸设计..................................................................................................163.3按照弯扭合成应力校核轴的强度..................................................................................193.4蜗轮轴的轴承选择与校核..............................................................................................223.5蜗杆轴的轴承选择与校核..............................................................................................263.6键的选择与校核..............................................................................................................293.6.1蜗轮与轴配合采用平键连接...............................................................................293.6.2蜗轮轴与联轴器之间用键连接...........................................................................303.6.3蜗杆轴与联轴器之间用键连接...........................................................................304.蜗轮蜗杆减速器箱体及其他辅助零件设计、装配..................................................................314.1密封圈的选择..................................................................................................................314.2弹簧垫圈的选择..............................................................................................................324.3箱体尺寸设计................................................
