I提供全套毕业设计摘要本设计是对载货汽车设计一个结构合理、工作性可靠的双级主减速器。此双级主减速器是由两级齿轮减速组成。与单级主减速器相比,在保证离地间隙相同时可得到很大的传动比,并且还拥有结构紧凑,噪声小,使用寿命长等优点。本文论述了双级主减速器各个零件参数的设计和校核过程。设计主要包括:主减速器结构的选择、主、从动锥齿轮的设计、轴承的校核。主减速器是汽车传动系中减小转速、增大扭矩的主要部件,它是依靠齿数少的锥齿轮带动齿数多的锥齿轮。对发动机纵置的汽车,其主减速器还利用锥齿轮传动以改变动力方向。全套图纸,加153893706关键词:载货汽车;双级主减速器;齿轮;校核;设计IIABSTRACTThisdesignisdesignsastructuretothetrucktobereasonable,workrelatedreliabletwo--pareswiththesinglestagemaingearbox,whentheguaranteegroundclearanceisthesamemayobtaintheverygreatvelocityratio,pact,thenoiseissmall,-putationandtheselectionprocess,:Maingearboxstructurechoice,host,drivenbevelgear'sdesign,bearing',increasedthetorque,,:Truck;Two-stageMainReductionGear;Gear;Check目录摘要.....................................................................................................................................IAbstract............................................................................................................................II第1章绪论.........................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................
