毕业设计（论文）题目Ф1.8×14型转筒干燥机传动系统与支撑装置设计系别航空与机械工程系专业名称机械设计制造及其自动化班级学号学生姓名指导教师二O一四年五月Ф1.8×14型转筒干燥机的传动系统与支撑装置的设计摘要：本课题的目的就是设计一转筒干燥机的传动系统与支撑装置。转筒干燥器主要有以下主要部分组成。筒体是一主要部分其外廓尺寸决定于反应或操作所需要的空间。筒上装有滚圈，筒体及筒中所装物料的重量，通过滚圈而传给支座的托轮，支座装有防止筒体作轴向窜动的装置。靠近托轮一挡轮座的筒体上，装有齿圈，以带动筒体回转。装在减速箱轴上的齿轮与此齿圈相连，减速器和电动机构成一传动装置。在转筒的物料端，装有一个小室，为卸出物料及传入或引入引出气体而用。筒的出料端用密封装置（迷宫或端面式的密封）加以密封。在筒的一端设有卸料装置，用以加卸出被处理的固体物料。被处理的物料与气流在转筒内即可以并流，也可以逆流。通过任务书中的条件参数，确定传动系统方案与支撑装置方案。画出系统传动简图；确定电动机型号及齿轮配置；传动功率的设计，传动参数与减速器的选择，传动件设计；熟练应用CAD绘制传动装置减速器的三维装配图。画出托轮简图；支撑装置受力的分析；研究设计轴承与托轮；设计挡轮与轴承。阅读文献，编写技术文件，编写设计说明书关键词：转筒干燥机传动装置减速器支撑装置PAGE\*MERGEFORMAT1Ф1.8×14typerotarydrumdryerandthesupportdeviceisdesignedtodriveAbstract:Thepurposeofthissubjectistodesignthetransmissionsystemofarotarydryerandthesupportdevice.Rotarydrumdryermainlyhasthefollowingmainparts.Thebarrelbodyisneededinthereactionoroperatingspacedeterminesamajorpartofthecontoursize.Cylinderisprovidedwithrollingring,materialbarrelbodyandbarrelweight,throughtherollertorollerbearings,bearingsarrangedforpreventingcylinderdeviceforaxialmovement.Nearthewheelcylinderwheelgearseat,agearring,todrivetherotatingcylinder.Installedinthegearboxshaftgearandthegearringisconnectedwiththemotor,reducerandatransmissiondevice.Intheendofrotarydrummaterials,providedwithachamber,usedfordischargingmaterialsandincomingorintroducederivativegas.Barrelendsealingdevice(labyrinthsealorfacetype)tobesealed.Adischargingdeviceatoneendofthebarrel,toaddasolidmaterialisprocessed.Thematerialandtheairisprocessedinthedrumcanflow,canalsobecountercurrent.Throughthetaskbookconditionparameters,determiningthetransmissionsystemandthesupportingdevicescheme.Drawthesystemtransmissiondiagram;determinethetypeofmotorandgearconfiguration;designoftransmissionpower,transmissionparameterselectionandreducer,transmissionpartsdesign;3DassemblydrawingskilledapplicationofCADdrawinggearreducer.Drawrollerdiagramanalysissupportingdevice;stress;researchanddesignofbearingandroller;designofgearwheelandbeari
