普通车床主轴箱设计第页共NUMPAGES68页毕业设计(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，主要包括三方面的设计，即：根据设计题目所给定的机床用途、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的计算转速，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）的刚度、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的设计。【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,designandmotiveofcompletionsportspreadthelordtomovetheproject"thestructureturn"afterdesign,designaprincipalaxistobecomesoonaboxassemblediagramandsparepartsdiagramandlayparticularemphasisontocarryonspreadtomovestalkmodule,principalaxismoduleandbecomesoonorganization,boxabody,lubricateandsealcompletely,spreadtomovestalkandslipperymovewheelgearsparepartsofdesign.【Keyword】principalaxisbox,becomesoonsystem,principalaxis.目录TOC\o"1-3"\h\z\uHYPERLINK\l"_Toc231889031"目录PAGEREF_Toc231889031\h4HYPERLINK\l"_Toc231889032"1、绪论PAGEREF_Toc231
