红河学院本科毕业设计(设计)摘要球磨机用于粉磨各种矿石及其它物料，被广泛用于选矿厂、建材、化工、冶金、材料及电力部门等若干基础行业的物料粉碎中得到广泛的应用，而且在今后相当长的时间内仍将是物料粉碎的主要设备。所以，生产低成本、轻便、简单、自动、节能、高效、稳定、可靠、操作方便的球磨机，仍是目前人们研究的课题，特别是传动部分的研究，对改进整台机器的工作性能至关重要。本文主要针对小型球磨机传动部分进行设计和研究，主要做了两方面的工作。第一计算，对已知条件结合实际进行分析，先分配传动比，再根据传动比，进行齿轮的设计、计算和校核等，把齿轮尺寸确定后，在进行轴的设计、计算和校核，同时选取轴承及联轴器等标准间，确定好轴的几何尺寸，然后再进行箱体尺寸计算及选取螺栓、螺母等标准件和齿轮结构的设计；其次绘图，做完以上工作之后，主要利用AutoCAD软件绘制二维齿轮、轴、箱体、端盖、套筒、传动部齿轮座等图纸及装配图，还绘制了部分零件的三维图。关键词：球磨机；齿轮；轴；减速器；AutoCAD绘图红河学院本科毕业设计(设计)ABSTRACTGrindingmachinecanbeusedinallkindsoforesandothermaterials,andiswidelyusedinconcentrator,buildingmaterials,chemicalindustry,metallurgy,materialsandsomebasicindustriessuchaselectricitydepartmentmaterialcrushingwidelyappliedinthefuture,andquitealongtimewillstillbethemainmaterialcrushingequipment.So,producinglow-cost,light,simple,automatic,energysaving,highefficiency,stableandreliable,convenientoperationofballmill,stilliscurrentthepeopleofresearch,especiallythetransmissionpart,toimprovetheperformanceofthewholemachineisveryimportant.Thisarticlemainlyaimsatthesmallballmilltransmissionpartdesignandresearch,mainlydonetwoaspects.Firstcalculationandtheknownconditionanalysis,practical,andthenbasedonfirstdistributionratioofgeartransmission,design,calculationandcheckthegear,determined,insizethedesignandcalculationofaxis,andatthesametimeandcheckselectionbearingsandcouplingstandardrooms,suchastodeterminethegeometrysize,goodshaftagainnextcabinetsizecalculationandselectingbolt,nutandotherfastenerandgearstructuredesign;Secondgraphics,finishaboveafterwork,themainuseAutoCADsoftwarerendering2dgear,shaft,body,cover,sleeve,transmissionpartssuchasassemblydrawingsandgearseat,alsopaintedparts3dmap.Keyword:ballmill;gear;shaft;reducer;AutoCADdrawing红河学院本科毕业设计(设计)目录第一章前言...................................................................................................................................11.1球磨机的概述....................................................................................................................11.2AutoCAD的概述...............................................................................................................11.3UGNX的概述...................................................................................................................11.4球磨机设计的目的和意义................................................................................................2第二章球磨机组成和工作原理...................................................................................................32.1球磨机的组成和工作原理................................................................................................32.1.1球磨机的组成.................................................................................................................32.1.2球磨机工作原理.............................................................................................................52.2球磨机传动........................................................................................................................5第三章小型球磨机传动部件设计和计算...................................................................................63.1传动方案的设计................................................................................................................63.1.1齿轮传动、带传动和涡轮蜗杆传动的特点.................................................................63.1.2传动方案的确定及传动比的分配.................................................................................63.2齿轮的设计........................................................................................................................73.2.1减速器中高速级齿轮的设计.........................................................................................73.2.2减速器中低速级齿轮的设计.......................................................................................113.2.3传动部齿轮的设计.......................................................................................................113.3轴的设计..........................................................................................................................113.3.1减速器中高速轴的设计...............................................................................................113.3.2减速器中间轴的设计...................................................................................................153.3.3减速器低速轴的设计...................................................................................................163.3.4小齿轮传动轴的设计...................................................................................................163.4减速器箱体及齿轮结构设计..........................................................................................173.4.1减速器箱体设计............................................................................................................173.3.2腹板式结构的齿轮设计................................................................................................18第四章小型球磨机传动部件主要零部件三维建模.................................................................204.1主要零件三维实体建模..................................................................................................204.2三维总装图和部分零件图..................................
