I摘要搅拌可以使两种或多种不同的物质在彼此之中互相扩散,从而达到均匀混合;也可以加速传质和传热过程。在工业生产中,搅拌操作是从工业开始的,围绕食品、纤维、造纸、石油、水处理、建筑等,作为工艺过程的一部分而被广泛应用。本文就以建筑为中心设计一款小型混凝土搅拌机。本设计的小型混凝土搅拌机是强制式搅拌机中的一种,搅拌非常均匀,质量好,生产效率高,成本低。其主要组成结构包括:电动机、带传动、减速器、链传动、搅拌结构及机架等。主要设计计算内容是小型混凝土搅拌机搅拌装置的设计及其校核,搅拌轴的连接及强度校核,各部分在机架中的安装位置设计已达到小巧方便的设计要求。本设计完成了总体结构的拟定,通过设计计算和校核,确定了各组成部分的结构尺寸和形状,实现了混凝土搅拌的功能。关键词:搅拌机;立轴;混凝土;搅拌装置;传动系统IIABSTRACTMixingcanmaketwoormoredifferentmaterialsinthespreadofeachother,soastoachievethesmooth;mixAlsocanaccelerateandmassandheattransferprocess.Inindustrialproduction,stirring,fromthestartoftheindustrialoperation,aroundfood,fibre,papermaking,oil,watertreatment,constructionandsoon,aspartoftheprocessandhasbeenwidelyused.Thisessay,takingconstructionasthecenterdesignasmallconcretemixerforreference.Thedesignofsmallconcretemixerisacompulsorymixer,themixingisveryuniform,goodquality,highefficiencyandlowcost.Itscompositioninclude:motor,beltdrive,gearreducer,chaindrive,mixingstructureandrack.Calculatethecontentofthemaindesignisthedesignandcheckingofthesmallconcretemixer,agitator,stirringshaftconnectionandstrengthcheckallpartsoftheinstallationlocationintherackhasbeendesignedtoachievecompactandconvenientdesignrequirementsThedesigniscompletedtheoverallstructureoftheformulation,designcalculationandverificationtodeterminethestructuresizeandshapeofthevariouscomponentsoftheconcretemixing.Keywords:Mixer;Verticalshaft;Concrete;Mixingunit;TransmissionsystemIII目录摘要..............................................................................................IABSTRACT........................................................................................II第1章绪论..................................................................................11.1研究的目的意义................................................................11.1.1混凝土的组成..........................................................21.1.2搅拌的任务.............................................................21.1.3搅拌机设计的意义...................................................31.2国内外混凝土搅拌机的发展状况......................................31.3设计内容..........................................................................41.4设计任务书.......................................................................51.4.1设计的依据及要求...................................................51.4.2产品的用途及使用范围...........................................5第2章总体设计方案...................................................................62.1总体方案设计...................................................................62.1.1混凝土搅拌机种类和功能比较.................................62.1.2混凝土搅拌机的结构型式选择.................................72.2总体结构及工作原理........................................................72.2.1结构组成及工作原理...............................................72.2.2主要技术参数..........................................................8第3章主要结构设计与计算.........................................................93.1主要工作部件的设计........................................................93.1.1搅拌装置的设计......................................................93.1.2机架的设计.............................................................93.2传动系统的设计..............................................................103.2.1传动比分配及电动机选型......................................103.2.2V带传动的设计....................................................113.2.3减速器选型...........................................................183.2.4链传动的设计........................................................193.3主轴设计与计算..............................................................213.3.1轴的计算过程........................................................21IV3.3.2键与轴承的选择....................................................223.3.3轴的强度校核........................................................233.3.4轴承组合的设计....................................................27第4章结论................................................................................28致谢...........................................................................................29参考文献.......................................................................................30VCONTENTSABSTRACT....................................................................................IIThefirstchapterintroduction.........................................................11.1Thepurposeoftheresearchsignificance.............................11.1.1Thecompositionoftheconcrete................................21.1.2Mixingtask..............................................................21.1.3Thesignificanceofthemixingmachinedesign..........31.2Thedevelopmentsituationofconcretemixerathomeandabroad.......................................................................................31.3Designcontent...................................................................41.4Thedesignplandescriptionsofthe....................................51.4.1Thedesignbasisofandrequirements........................51.4.2Theuseoftheproductsandusescope.......................5Chapter2Theoveralldesignscheme...........................................62.1Thegeneralschemedesign.............
