普通车床主轴箱设计

毕业设计(论文)摘要普通中型车床主轴箱设计普通中型车床主轴箱设计，主要包括三方面地设计，即：根据设计题目所给定地机床用途、规格、主轴极限转速、转速数列公比或级数，确定其他有关运动参数，选定主轴各级转速值；通过分析比较，选择传动方案；拟定结构式或结构网，拟定转速图；确定齿轮齿数及带轮直径；绘制传动系统图.其次，根据机床类型和电动机功率，确定主轴及各传动件地计算转速，初定传动轴直径、齿轮模数，确定传动带型号及根数，摩擦片尺寸及数目；装配草图完成后要验算传动件（传动轴、主轴、齿轮、滚动轴承）地刚度、强度或寿命.最后，完成运动设计和动力设计后，要将主传动方案“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地设计.【关键词】车床、主轴箱、变速系统、主轴组件.ABSTRACTThecommonandmedium-sizedlatherprincipalaxisboxdesignCommonandmedium-sizedlatherprincipalaxisboxdesign,mainlyincludethedesignofthreeaspects,namely:Accordingtodesigntopicgivesettleofthetoolmachineuse,specification,principalaxisextremelimitturnsoonandturnsoonthefewrowsmaleratioorseries,certainotherrelevantsportparameter,makeselectionprincipalaxisalllevelstoturntosoonbeworth。Passananalysiscomparison,choosetospreadtomoveaproject。Draftstructuretypeorstructurenet,drafttoturnsoondiagram。CertainwheelgearChinumberandtakeadiameter。Drawtospreadtomovesystemdiagram.Secondly,accordingtothetoolmachinetypeandtheelectricmotorpower,makesurethatprincipalaxisandeachcalculationwhichspreadtomoveapieceturnsoon,thebeginningcertainlyspreadstomoveastalkdiameter,wheelgearmoldnumber,makesuretospreadtomovetotakemodelnumberandnumber,frictionslicesizeandnumber。Afterassembleagrassdiagram'scompletionwanttochecktospreadtomoveapiece(spreadtomovestalk,principalaxis,wheelgearandrolloverbearings)onthewholeofjustdegree,strengthorlifespan.End,designandmotiveofcompletionsportspreadthelordtomovetheprojectthestructureturnafterdesign,designaprincipalaxistobecomesoonaboxassemblediagramandsparepartsdiagramandlayparticularemphasisontocarryonspreadtomovestalkmodule,principalaxismoduleandbecomesoonorganization,boxabody,lubricateandsealcompletely,spreadtomovestalkandslipperymovewheelgearsparepartsofdesign.【Keyword】principalaxisbox,becomesoonsystem,principalaxis.目录目录..........................................................................................................................................................31、绪论....................................................................................................................................................62．设计计算............................................................................................................................................72.1普通车床地规格............................................................................................................................72.1.1车床地规格系列和用处.........................................................................................................72.1.2操作性能要求.........................................................................................................................73.主动参数参数地拟定...........................................................................................................................73.1确定传动公比73.2主电动机地选择............................................................................................................................84.变速结构地设计...................................................................................................................................94.1主变速方案拟定............................................................................................................................94.2变速结构式、结构网地选择........................................................................................................94.2.1确定变速组及各变速组中变速副地数目.............................................................................94.2.2变速式地拟定.......................................................................................................................104.2.3结构式地拟定.......................................................................................................................104.2.4结构网地拟定.......................................................................................................................104.2.5结构式地拟定.......................................................................................................................114.2.6结构式地拟定.......................................................................................................................114.2.7确定各变速组变速副齿数...................................................................................................134.2.8绘制变速系统图...................................................................................................................145.结构设计.............................................................................................................................................145.1结构设计地内容、技术要求和方案..........................................................................................145.2展开图及其布置..........................................................................................................................155.3I轴（输入轴）地设计................................................................................................................155.4齿轮块设计..................................................................................................................................165.
