NGW行星轮减速器设计

洛阳理工学院毕业设计（论文）INGW行星减速器的设计摘要本文完成了对一级行星齿轮减速器的结构设计。该减速器具有较小的传动比，而且，它具有结构紧凑、传动效率高、外廓尺寸小和重量轻、承载能力大、运动平稳、抗冲击和震动的能力较强、噪声低的特点，适用于化工、轻工业以及机器人等领域。这些功用对于现代机械传动的发展有着较重要的意义。首先简要介绍了课题的背景以及齿轮减速器的研究现状和发展趋势，然后比较了各种传动结构，从而确定了传动的基本类型。论文主体部分是对传动机构主要构件包括太阳轮、行星轮、内齿圈及行星架的设计计算，通过所给的输入功率、传动比、输入转速以及工况系数确定齿轮减速器的大致结构之后，对其进行了整体结构的设计计算和主要零部件的强度校核计算。其中该减速器的设计与其他减速器的结构设计相比有三大特点：其一，为了使三个行星轮的载荷均匀分配，采用了齿式浮动机构，即太阳轮与高速轴通过齿式联轴器将二者连接在一起，从而实现了太阳轮的浮动；其二，该减速器的箱体采用的是法兰式箱体，上下箱体分别铸造而成；其三，内齿圈与箱体采用分离式，通过螺栓和圆锥销将其与上下箱体固定在一起。最后对整个设计过程进行了总结，基本上完成了对该减速器的整体结构设计。关键词：行星齿轮，传动机构，结构设计，校核计算洛阳理工学院毕业设计（论文）IIThedesignofNGWplanetarygearreducerABSTRACTThiscompletedasingle-stageplanetarygearreducerdesign.Thegearhasasmallertransmissionratio,andithasacompact,hightransmissionefficiency,outline,smallsizeandlightweight,carryingcapacity,smoothmotion,shockandvibrationresistantandlownoisecharacteristics,Usedinchemical,lightindustryandroboticsfields.Thefunctionofthedevelopmentofmodernmechanicaltransmissionhasamoreimportantsignificance.Firstpaperintroducesthebackgroundandthesubjectofgearreducersituationanddevelopmenttrend,andthencomparedvarioustransmissionstructures,whichdeterminethebasictypeoftransmission.Thesisisthemainpartofthemaincomponentsofdrivemechanismincludingthesunwheel,planetgear,ringgearandplanetcarrierinthedesigncalculation,givenbytheinputpower,gearratio,inputspeedandtheconditionfactortodeterminetheapproximatestructureafterthegearreducerAndtocarryoutthedesignandcalculationoftheoverallstructureandmaincomponentsofthestrengthcheckcalculation.Oneoftheothergearreducerdesignandcomparedthestructuraldesignofthethreemajorcharacteristics:First,thethreeplanetarygeartomaketheloadevenly,usingagear-typefloatingbody,thesungearandhigh-speedshaftthroughthegeartogetherCouplingthetwotogethertoachieveafloatingsungear;Second,theboxusesareducerflangebox,upperandlowerboxwerecast;Third,theringgearandBoxwithseparate,throughboltsandtaperedpinswillbefixedtogetherwiththeupperandlowerbox.Finally,asummaryoftheentiredesignprocessisbasicallycompletetheoveralldesignofthereducer.KEYWORDS:planetarygear，drivingmachanism，structuraldesign，checkingcalculation洛阳理工学院毕业设计（论文）III目录前言................................................................................................1第1章传动方案的确定...................................................................61.1设计任务...............................................................................61.1.1齿轮传动的特点.........................................................61.1.2齿轮传动的两大类型.................................................71.2行星机构的类型选择............................................................71.2.1行星机构的类型及特点..............................................71.2.2确定行星齿轮传动类型............................................10第2章齿轮的设计计算.................................................................122.1配齿计算.............................................................................122.1.1确定各齿轮的齿数...................................................122.1.2初算中心距和模数...................................................132.2几何尺寸计算.....................................................................142.3装配条件验算.....................................................................172.3.1邻接条件...................................................................172.3.2同心条件...................................................................172.3.2安装条件...................................................................182.4齿轮强度校核.....................................................................192.4.1a-c传动强度校核......................................................192.4.1c-b传动强度校核......................................................24第3章轴的设计计算.....................................................................293.1行星轴设计.........................................................................293.2转轴的设计.........................................................................313.2.1输入轴设计...............................................................313.2.2输出轴设计...............................................................32第4章行星架和箱体的设计.........................................................354.1行星架的设计.....................................................................354.1.1行星架结构方案.......................................................35洛阳理工学院毕业设计（论文）IV4.1.2行星架制造精度.......................................................374.2箱体的设计.........................................................................39结论..............................................................................................42谢辞................................................................................................43参考文献..........................................................................................44附录..............................................................................................45外文资料翻译..................................................................................48洛阳理工学院毕业设计（论文）V主要代号代号意义单位代号意义单位a'a0abC*Cd0dadbdfd'deFnFrFtFFfpbfptfHHBHRCah*ahfh中心距、标准中心距角度变位齿轮的中心距切齿中心距齿宽顶隙顶隙系数直径
