文档介绍：本科生毕业设计I黄河少帅自卸车双级主减速器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。关键词:载货汽车;双级主减速器;齿轮;校核;设计本科生毕业设计IIABSTRACTThisdesignisdesignsastructuretothetrucktobereasonable,workrelatedreliabletwo--pareswiththesinglestagemaingearbox,whentheguaranteegroundclearanceisthesamemayobtaintheverygreatvelocityratio,pact,thenoiseissmall,-putationandtheselectionprocess,:Maingearboxstructurechoice,host,drivenbevelgear'sdesign,bearing',increasedthetorque,,:Truck;Two-stageMainReductionGear;Gear;Check本科生毕业设计目录摘要.....................................................................................................................................IAbstract............................................................................................................................II第1章绪论............................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................
