本科毕业设计（论文）通过答辩I摘要螺旋输送机是一种不具有挠性牵引构件的旋转类型的物料输送机械，是现代化生产和物流运输不可缺少的重要机械设备之一。它的广泛应用对于提高劳动生产率，实现物料输送过程的机械化和自动化，都具有重要的现实意义。对于螺旋输送机，在工程设计及使用中还存在一些的缺陷，如参数选择不合理等。目前，螺旋输送机的设计仍是依靠经验公式计算，在经验公式中许多参数的选择是在一定范围内凭经验选取的，这使得螺旋输送机的设计较落后，无法提高其设计水平和提高产品的性能。文中对螺旋输送机进行了较全面论述，了解了螺旋输送机的类型、发展现状。阐明了螺旋输送机的工作原理。并根据螺旋输送机的工作原理、工作条件、输送要求等设计一螺旋输送机。该螺旋输送机用于水泥的水平输送，根据输送量以及输送路程设计出螺旋直径，计算了螺旋功率以及根据功率选择了电动机、减速器和联轴器能较好地解决实际问题。最后对螺旋输送机的安装及平时保养做出了总结。整个设计对今后的设计工作将有实际指导意义和价值。关键词:螺旋输送机;连续运输机械;螺旋直径本科毕业设计（论文）通过答辩IIAbstractThescrewconveyoristhenecessarydeviceofmodernmanufacturingandmaterialfluidtransportation.Inordertoreducepeople'sheavyphysicalwork,toraiseworkingproductivity,toachievematerial-conveyingautomationandmechanization,itpossessesveryimportantpracticalsignificance.Ithasalreadywidelyusedinmanycountrydepartments.Screwconveyorsareusedextensivelyinindustryforconveyingandelevatingbulkmaterialsoverrelativelyshortdistances.Theyareveryeffectiveconveyingdevicesforrelativelyfreeflowingbulksolids.Thispapercomesfromaninvestigationpracticalproblem,whichisputforwardduringtheinstituteofconstructionmachineryresearchmakessomesurveys.Infact,forscrewconveyors,therearemanyproblemsindesign,use,engineering,suchasconfigurationdesign,non-reasonableinparameterschoiceandnotconvenienceofactingmachines.Thusthereisoftendefectwhenmaterialsareconveyed,forexample,materialsjam,noise,powerwastage.Theseproblemsneedurgentsettlements.Thetextofthescrewconveyorinamorecomprehensivediscussionaboutthetypeofscrewconveyor,thedevelopmentofthestatusquo.Toclarifytheworkingprincipleofthescrewconveyor.Screwconveyorinaccordancewiththeworkingprinciple,workingconditions,transportationrequirementstodesignascrewconveyor.Thescrewconveyorforconveyingthelevelofcement,accordingtothroughputandtransmissiondistancediameterspiraldesign,computingpower,aswellasaspiralinaccordancewiththepowertochooseamotor,reducerandcouplingtosolvepracticalproblems.Atlast,someresearchworkismadeabouttheinfluencesofparametersduringscrewconveyorsconveyingbulks.Thiscandirectlaterresearchworkaboutscrewconveyorsdesignwork,andhaspracticalsignificance.KeyWords:screwconveyor;continuoustransportationmachine;screwdiameter本科毕业设计（论文）通过答辩III目录摘要..................................................................................................................................................IABSTRACT....................................................................................................................................II前言.................................................................................................................................................1第1章毕业设计的目的和任务...................................................................................................21.1毕业设计的目的..................................................................................................................21.2毕业设计的任务..................................................................................................................21.2.1设计条件.......................................................................................................................31.2.2设计内容.......................................................................................................................31.2.3设计关键.......................................................................................................................31.2.4设计要求.......................................................................................................................3第2章螺旋输送机的基本现状...................................................................................................52.1螺旋输送机的工作原理及特点...........................................................................................52.2螺旋输送机的发展历史及趋势...........................................................................................62.2.1螺旋输送机的发展历史...............................................................................................62.2.2螺旋输送机的发展趋势..............................................................................................102.2.3螺旋输送机的应用范围.............................................................................................102.3螺旋输送机的研究现状..................................................................................................11第3章螺旋输送机的设计与参数选用.....................................................................................143.1螺旋输送机的设计方法.....................................................................................................143.1.1螺旋输送机现代设计方法..........................................................................................153.1.2螺旋输送机的常规设计..............................................................................................173.2螺旋输送机的具体设计.....................................................................................................173.2.1螺旋输送机的选型.....................................................................................................173.2.2螺旋输送机的设计计算............................................................................
