上海工程技术大学毕业设计(论文)ESU7160型乘用车变速器总体设计各专业完整优秀毕业论文设计图纸摘要本设计通过对对现有的各类型的变速器进行研究与分析，设计了一款横置两轴式五档手动变速器。首先制定了变速器的总体方案，计算选择中心距的大小，齿轮的模数等，确定倒档的布置形式，确定齿轮的压力角，螺旋角，齿宽，齿形系数等，然后计算变速器的各档传动比，各齿轮的参数，通过变位系数图查找计算变位系数，然后对各档齿轮进行变位，并对齿轮进行校核。计算了轴各段的长度和轴颈大小，并对轴和轴承进行校核计算，再对壳体进行计算，确保设计出来的产品能够达到国家标准和行业标准。对于本次设计的变速器来说，其特点是：扭矩变化范围大可以满足不同的工况要求，从而达到其经济性和动力性的要求。采用了两轴式结构，工作可靠，结构简单，而且采用同步器挂档，可以使变速器挂档平稳，噪声降低。所有传动齿轮为斜齿轮，使用寿命长，工作时噪声低，没有直齿轮的啮合冲击现象，运行比较平稳。本次设计达到任务书的规定。关键字：两轴式；五档；手动变速器；机械齿轮变速器；同步器换挡ESU7160OverallDesignofTransmission-typePassengerCarsABSTRACTThedesignofasystemforthepassenger-depthstudyoftransmission.Throughvarioustypesofexistingtransmissionandanalysisoflearningandtheknowledgeacquiredwiththeirown,designedatwo-axistransversefive-speedmanualtransmission.First,theresearchliteraturethroughthetransmissionoftheoverallprogramdevelopedtocalculatethesizeofthecenterdistancechosen,themodulusandothergeartodeterminethereverseofthelayout,determinethegearpressureangle,helixangle,toothwidth,toothcoefficient,thencalculatethetransmissionofthefiletransmissionratio,theparametersofthegear,lookthroughthemodificationcoefficientdiagrammodificationcoefficientcalculated,thenthedeflectionoftheGear,andthegearswerechecked.Calculatethelengthoftheaxisofeachsegmentandthejournalsize,andtheshaftandbearingcheckingcalculations,andthenchecktheshelliscalculatedtoensurethattheproductsdesignedtomeetnationalstandardsandindustrystandards.Thetransmissionofthisdesign,itsfeaturesare:largetorquerangetomeetdifferentworkingconditions,asimplestructure,easyproduction,useandmaintenance,lowcost,andtheuseofhangingfilesynchronizercanbelinkedtotransmissionfileasmooth,noisereduction,teetheasilydamaged.Inthedesignofa5+1speedmanualtransmission,thetransmissiongearratiobyalargerrangetomeetthevehiclerequirementsindifferentconditions,soastoachieveitseconomicanddynamicrequirements.Afternearlysixmonthsofstudyandwork,thisdesigncanbemoresatisfactorycompletionofthefinal,requiredtoachievethemissionstatementofthelearningcontent,success
