齿轮减速器设计与三维建模摘要本文在对二级斜齿圆柱齿轮减速器参数优化的基础上，利用Pro/E软件建立了减速器的三维实体模型并进行虚拟装配，其重点是关键部件斜齿圆柱齿轮的参数化建模过程。最后对该模型进行运动学仿真分析，给输入轴一定转速，由仿真分析得出中间轴和输出轴转速，并将仿真结果与理论计算进行对比，从而验证该结构的有效性和可行性。本文主要从以下几个方面来进行齿轮减速器的设计：第一，合理的传动装置总体的设计，了解机械传动装置的原理及参数搭配，为设计各级传动件和装配草图提供依据。第二，传动零件的设计计算及齿轮、轴、滚动轴承、联轴器的设计选择与校正，为进行装配草图的设计做好准备。第三，减速器结构及其附件的设计以便提高效率、降低成本，使维修简单。第四，减速器装配图和零件工作图的设计以便进行机器装配、调试及维护。关键词：齿轮减速器；箱体；机械传动装置；原理及参数；设计；运动分析；Pro/EGearreducerdesignwiththreedimensionalmodelingAbstractThispaperisbasedonthedesignofmechanicaldesigncourseteachingpracticeintwo-stagehelicalgearreduceronthebasisoffurtheroptimization,usingPro/Esoftwaretoestablishathree-dimensionalmodelreducerandthevirtualassembly,focusingonkeycomponentsoftheprocessofparametricmodelinggear.Finally,kinematicsimulationofthemodel,somegiveninputshaftspeed,obtainedbythesimulationspeedintermediateshaftandoutputshaft,thesimulationresultswillbecomparedwiththetheoreticalcalculation,toverifytheeffectivenessandfeasibilityofthestructure.Thisarticleismainlyfromthefollowingaspectstoacylindricalgearreducerdesign:First,reasonablegeardesign,understandingthemechanicaltransmissionprincipleandparametermatchingdesignlevels,transmissionpartsandAssemblySketchesprovideabasis.InSecond,designandcalculationoftransmissionparts,gear,shaft,bearing,couplingdesignchoicesandcorrection,toprepareforthedesignoftheassemblydrawing.Third,thedesignofgearreducerstructureanditsaccessoriesinordertoimproveefficiency,reducecost,makethemaintenanceeasy.Fourth,thedesignofthereducerassemblydrawingandpartsworkingdrawingformachineassembly,commissioningandmaintenance.Keywords:Gearreducer；Casing；Amechanicaltransmissiondevice；PrincipleandParameter；Design；KinematicsAnalysis；Pro/E目录1绪论......................................................................................................................11.1选题背景..................................................................................................11.2选题意义..................................................................................................11.3减速器的国内外现状及发展趋势..........................................................21.4减速器的分类及载荷分类......................................................................31.5设计的主要工作......................................................................................41.6设计的总结及展望未来..........................................................................42传动装置的总体设计..............................................................................................62.1传动装置简图..........................................................................................62.2设计任务..................................................................................................62.3传动装置总体设计方案..........................................................................62.4电机的选择..............................................................................................62.4.1选择电机的类型...............................................................................72.4.2确定电动机功率...............................................................................72.4.3确定电机转速...................................................................................72.5传动比的分配及转动校核......................................................................82.6传动装置的运动和动力参数的计算......................................................82.7V带的传动设计......................................................................................92.8齿轮传动的设计....................................................................................112.8.1高速级齿轮传动的设计.................................................................112.8.2低速齿轮机构设计.........................................................................162.9传动轴的设计........................................................................................202.9.1高速轴的设计.................................................................................202.9.2中间轴的设计.................................................................................232.9.3低速轴的设计.................................................................................302.10滚动轴承的校核计算..........................................................................332.11平键联接的选用和计算......................................................................342.12联轴器的选择计算..............................................................................352.13箱体及其附件的设计选择..................................................................352.14润滑密封设计......................................................................................363三维建模................................................................................................................373.1轴的设计................................................................................................373.2键的设计................................................................................................383.3齿轮的设计............................................................................................383.4装配图的设计.............................................................................
