离心式选粉机立轴结构设计(毕业论文)

IФ5m离心式选粉机立轴结构设计摘要近10年来，水泥工业的蓬勃发展，带来了水泥工艺、装备的更新换代。水泥圈流生产在全国8000多家水泥厂中已经占有相当大的比重，保守估计已过5成。其中又有近半数厂家使用着离心式选粉机，由于离心式选粉机结构、工艺简单，不必使用风机及收尘系统，一次性投资较小，与开流系统相比，效益显著。本课题主要是立轴的结构设计，特别是大小风叶和撒料盘的的结构设计。对于大小风叶主要改进了风叶座的尺寸和形状，是它更加符合人们的需求。对于撒料盘主要是将平盘型撒料盘改为径向带凸棱式撒料盘，又增加了撞击导料板。这种改进既保留了原有选粉机的设备较轻，结构简单，占用空间较小的优点，又改变了原选粉机效率低的缺点。本次设计本着结合理论知识，尊重实践，即做到理论联系实际，去弊存优，增强功能而设计的新型产品。关键词：立轴，撒料盘，新型，改进IIDesignthestructuralofverticalshaftontheФ5mconversionofcentrifugalseparatorABSTRACTThistitlecomesfromthetabled.Thecementindustry’salfaromeobringaboutthecementtechnologyandequipment’upgrading.Theflowofproductioninthecountryaround8000familiesinthecementfactoryhasbeenquitealargeshareofthepastfive.Andnearlyhalfoftheuseofthestructure,plain,withouttheuseoftheblowerandthedustofthesystem.Disposablecapitalofthesmallerandopentheworkflowsystem.Remarkableresults.Myjobisdesignthestructureoftheverticalshaft,inparticularthebigandsmallfanbladesandscattersmaterialplate.Iimprovedtheseatoffanblades’sizeandcontour.Theyarefitofpeople’shabit.Mainlyflatdishesoftypeletgomaterialincreaseandassistwindleafonebyone.Theimprovementkeepformertohavepersonwhoselectspowerisequipmentrelativelylightstructuresimple,takespacepositionlessandchargeformerpowerselectingweakshortcoming,peallyitistheoddswiththecommunityortheleadershiptypethatselectsonceofthepowermachinetobeimprovegreatly.Inaword,thisimprovementin-linewithcombiningthebooks,respectpractice.Accomplishtheoryintegrateswithpractice,itgoesfrauddepositexcellentitstrengthensthefunction.Becausetimeurgesdarkgreenly,theknowledgelevelislimited,themistakesandslippingunavoidably.Hopecriticism.KEYWORDS：Verticalshaft，Scattersmaterialplate,Novel,ImproveIII目录前言.......................................................................................................1第1章离心式选粉机的基本知识............................................................4§1.1离心式选粉机的构造与工作原理..................................................4§1.2选粉细度调节............................................................................10第2章离心式选粉机工艺参数.............................................................12§2.1基本工艺参数............................................................................12§2.1.1主要工艺尺寸......................................................................12§2.1.2生产能力.............................................................................12§2.1.3主轴转速.............................................................................13§2.1.4功率....................................................................................13第3章离心式选粉机立轴结构设计......................................................14§3.1立轴的设计................................................................................14§3.1.1确定轴的最小直径...............................................................14§3.1.2确定轴上各标准件的规格....................................................15§3.1.3轴的校核.............................................................................15§3.1.4检验键的强度......................................................................20§3.1.5检验轴承的寿命..................................................................20第4章离心式选粉机零部件结构设计...................................................22§4.1减速箱箱体结构设计..................................................................22§4.2风叶座底座设计.........................................................................23§4.3风叶座结构设计.........................................................................24§4.4撒料盘结构设计.........................................................................24第5章离心式选粉机的相关调整..........................................................26§5.1小风叶的调整............................................................................26-IV-§5.2大风叶的调整............................................................................26§5.3隔风板的调整............................................................................26§5.4风口的调整................................................................................27§5.5主轴的调整................................................................................27第6章选粉机的维护修理.....................................................................28§6.1安装要求：................................................................................28§6.2锥齿轮安装及其运转中的技术要求：.........................................28§6.3壳体和回转部分的安装要求：...................................................29§6.4检修调整...................................................................................29§6.4.1选粉机内部主要磨损件的修理：.........................................30§6.4.2滚动轴承的拆卸修理...........................................................30§6.4.3大小锥齿轮装配间隙的调整................................................30§6.5操作维护...................................................................................31§6.5.1选粉机允许运转调价和运转过程中的严重缺陷程度：.........31§6.5.2启动前和运转中的检查工作：.............................................31§6.5.3润滑工作.............................................................................32§6.5.4故障原因及处理办法：.......................................................32第7章结论.................
