车床320床头箱设计【320mm-3kw-40-2000-1.26-18级】大学论文.doc

宁XX学院课程设计(论文)车床320床头箱设计所在学院专业班级姓名学号指导老师年月日摘要主传动系统设计是机床设计中非常重要的组成部分，本次设计主要由机床的级数入手，于结构式、结构网拟定，再到齿轮和轴的设计，再选择各种主传动配合件，对轴和齿轮及配合件进行校核，将主传动方案“结构化”，设计主轴变速箱装配图及零件图，侧重进行传动轴组件、主轴组件、变速机构、箱体、润滑与密封、传动轴及滑移齿轮零件的设计，完成设计任务。本次突出了结构设计的要求，在保证机床的基本要求下，根据机床设计的原则，拟定机构式和结构网，对机床的机构进行精简，力求降低生产成本；主轴和齿轮设计在满足强度需要的同时，材料的选择也是采用折中的原则，没有选择过高强度的材料从而造成浪费。【关键词】车床、主传动系统、结构式、电动机。AbstractMaindrivesystemdesignisVeryimportantpartoftheMachineDesign,Thedesignoftheseriestostartprimarilybymachine,Inthestructure,thestructurenetworkdeveloped,tothedesignofgearsandshafts,Chooseavarietyofmaindrivewiththepiecesoftheshaftandgear,andcheckedwiththeparts，designandmotiveofcompletionsportspreadthelordtomovetheproject"thestructureturn",Designaprincipalaxistobecomesoonaboxassemblediagramandsparepartsdiagramandlayparticularemphasisontocarryonspreadtomovestalkmodule,principalaxismoduleandbecomesoonorganization,boxabody,lubricateandsealcompletely,spreadtomovestalkandslipperymovewheelgearsparepartsofdesigntocompletedesigntasks.Thishighlightsthestructuraldesignrequirements,underthebasicrequirementsforensuringthemachine,Accordingtotheprinciplesofmachinetooldesign,Developmentofinstitutionalandstructuralnet,Streamliningofthemachinetoolsector,Strivetoreduceproductioncosts,Nochoiceofmaterialsresultinginhighstrengthwaste.【Keywords】lather,Maindrivesystem,Structure,Electricmotor.全套图纸加扣扣401339828目录TOC\o"1-3"\h\uHYPERLINK\l"_Toc382510691"摘要PAGEREF_Toc382510691\h2HYPERLINK\l"_Toc382510692"绪论PAGEREF_Toc382510692\h5HYPERLINK\l"_Toc382510693"1.主轴极限转速的确定PAGEREF_Toc382510693\h5HYPERLINK\l"_Toc382510694"2.主动参数的拟定PAGEREF_Toc382510694\h7HYPERLINK\l"_Toc382510695"2.1确定传动公比PAGEREF_Toc382510695\h7HYPERLINK\l"_Toc382510696"2.2主电动机的选择PAGEREF_Toc382510696\h7HYPERLINK\l"_Toc382510697"3.普通车床的规格PAGEREF_Toc382510697\h9HYPERLINK\l"_Toc382510698"4.转速图的拟定PAGEREF_Toc382510698\h9HYPERLINK\l"_Toc382510699"4.1确定变速组及各变速组中变速副的数目PAGEREF_Toc382510699\h9HYPERLINK\l"_Toc382510700"4.2结构式基本组和扩大组的拟定PAGEREF
