ITYQ4190型汽车轮边减速器设计摘要本文根据TYQ4190型半挂牵引车的设计要求,完成了轮边减速器的设计。由于车速要求较高,且其载重量大,对其结构的强度要求较高。对比已有车型并考虑各种传动的优缺点选取轮边减速器的类型为NGW行星齿轮减速器,根据分配的传动比,初步确定齿数,然后按照扭矩特性和轮齿的弯曲强度公式计算出齿轮副的模数。计算出基础参数以后根据该参数设计齿轮副的其它尺寸和轮边减速器的结构参数。对该齿轮副进行效率检验和强度校核。同时对轴承和连接花键的选择和设计,并进行了强度校和。在轮边减速器校验合格后,运用UG对轮边减速器进行三维建模,创建的轮边减速器三维实体模型可以直观的看到各零件之间的匹配是否合理,有无干涉,是对设计尺寸的初步检验,而且也是对零件仿真分析和加工的一个基础。在三维图合理无干涉的情况下用CAD软件绘制图纸完成设计任务。关键词半挂牵引车,轮边减速器,UG,行星齿轮IIDesigningthewheelsideplanetaryreduceroftheTYQ4190AbstractInthisarticle,itintroducesthedesigningofthewheelsideplanetaryreducerofTYQ4190semitrailertowingvehicle.Accordingtothehighspeedandthelargeloads,weneedahigherstrengthofitsstructure.Referencetoexistingmodelsandconsidertheadvantagesanddisadvantagesofvarioustransmission,selectiontheNGWplanetarygearreducer.Accordingtothegivenparameters,choosethebestgearnumbersandthem.Principleisthatmakesurethesizeofthestructureisassmallaspossible.Calculatedallpartsofthestructuressize,andthencheckitsstrength.Designthestructureformsofthebearingsandthespline.Afterthecompletionofmechanicaldesign,wehavetoestablishthemainpartsofthethreedimensionalmodelwithUGsoftware.Whileestablishingthethreedimensionalofthegears,wecancheckthereasonablenessofaplanetarygear.Anditisthebaseofsimulationanalysisandprocessing.Keywordssemitrailertowingvehicle,wheelsideplanetaryreducer,UG,planetarygearII目录摘要....................................................................................................................................IAbstract..............................................................................................................................II引言............................................................................................................................11绪论..............................................................................................................................21.1轮边减速器文献综述...........................................................................................21.1.1轮边减速器分类及工作原理.....................................................................21.1.2国内外发展现状和发展前景.....................................................................41.2课题背景及开展研究的意义................................................................................51.2.1课题背景....................................................................................................51.2.2研究的意义................................................................................................51.3主要研究内容.......................................................................................................62齿轮传动的参数设计计算..............................................................................................72.1已知条件...............................................................................................................72.2设计计算...............................................................................................................72.2.1分配传动比................................................................................................72.2.2选取行星齿轮传动的传动类型和传动简图..............................................82.2.3配齿计算..................................................................................................112.2.4初步计算齿轮的主要参数.......................................................................123验算和效率的计算........................................................................................................163.1.装配条件的验算.................................................................................................163.2传动效率的计算.................................................................................................174行星齿轮的强度校核....................................................................................................194.1行星齿轮传动的受力分析..................................................................................194.2太阳轮行星轮齿轮副强度的校核....................................................................204.2.1齿面接触强度的校核计算.......................................................................204.3行星轮内齿圈齿轮副的校核.............................................................................294.3.1齿面接触强度的校核计算.......................................................................29II4.3.2齿根弯曲强度的校核计算.......................................................................315轴承载荷和寿命的校核................................................................................................325.1承载轴承的选用.................................................................................................325.2行星轮轴轴承的校核.........................................................................................336花键的选择和计算........................................................................................................346.1主动轴花键的选择及强度计算..........................................................................346.1.1花键副齿数与模数的确定.......................................................................346.1.2花键副的强度计算...................................................................................356.2其他花键的选择..........
