江西理工大学2011届专科生毕业设计江西理工大学南昌校区毕业设计题目：基于Solidworks的减速器的虚拟设计系：机电工程系专业：机电一体化技术班级：08机电一体化（2）班摘要在现代制造业中，研究开发以产品设计为目标，全过程综合应用CAD及相关一体化集成技术已成为必然趋势，这种趋势有利于提高产品的设计水平，并且缩短科研和新产品开发周期，大幅度提高劳动生产率。而减速器作为一种重要的动力传递装置，CAD技术被更广泛的应用到减速器设计中去。本文完成了减速器的机械设计后，利用Solidworks软件的有关命令完成一个一级圆柱齿轮减速器的三维模型及齿轮、轴、箱体等各个零件的三维建模，通过各个零件之间的配合关系加以约束，将各个零件模型装配起来，标准零件由Toolbox导入，装配到减速器实体中去，完成装配体，并利用该软件生成二维工程图，用干涉对零件各个部分进行检查，通过修改配合约束或者尺寸大小，消除零件之间的干涉情况，通过Solidworks软件插件Cosmosmotion的仿真运动功能，检查、优化设计方案，观察齿轮的啮合情况，并在最后输出齿轮啮合的动画。实现了减速器的运动仿真，完成了减速器在计算机上的虚拟设计。关键词：SolidWorks；减速器；三维建模；仿真ABSTRACTInmodernmanufacturingindustry,productdesignistheobjectiveofresearchanddevelopment,thecomprehensiveapplicationofthewholeprocessofintegrationofCADandrelatedintegratedtechnologyhavebecomeaninevitabletrend,whichisconducivetoraisingthelevelofproductdesign,andtoreduceconsumption,andnewproductsdevelopmentcycle,substantialincreaseinlaborproductivity.Thereducerisanimportantdrivingforcetransmissiondevice,therefore,CADtechnologyhasbeenappliedtoawiderrangeofgearboxdesign.Thepapercompletedthemechanicaldesignofthegearbox,usedSolidWorkssoftwaretocompletethethree-dimensionalmodelofgearboxandgear,shaft,tankandotherpartsofthethreedimensionalmodeling,relatedthevariouspartsandcomponentstotheassemblymodelbyconstraint,importedthestandardcomponentsfromtheToolbox,assembledthereducerentitiestocompletetheassemblyandusedthesoftwaretogeneratetwo-dimensionalengineeringdrawings,partsusedtointerfereinvariouspartsoftheinspection,bymodifyingthesizeconstraintsoreliminatinginterferencebetweenthepartsthroughSolidWorksSimulationsoftwareplug-inmotorfunctionCosmosmotiontocheckandoptimizethedesign,observedthematinggearandthemeshinggearsinthefinaloutputoftheanimation.Therealizationofthemotionsimulationofthegearboxwascompletedbasedonthecomputervirtualdesign.Keywords:SolidWorks；gearbox；three-dimensionalmodeling；Simulation目录第一章引言.........................................11.1减速器的概述.....................................1
