螺旋输送机的设计解析

毕业论文（设计）螺旋输送机的设计院系：专业：年级（班级）：姓名：学号:指导教师：职称：完成日期：II摘要螺旋输送机是利用电动机带动螺旋轴转动,使螺旋推移物料从而实现输送目的的机械,它能水平、倾斜或垂直输送,适合短距离输送，具有结构结构简单、体积紧凑、占地面积小、易于密闭、操作和管理方便等优点。本次任务是设计一台水平输送小麦、水稻等种类粮食螺旋输送机，输送量为30t/h，输送距离为8米，室内外均能适应。重点研究在与驱动装置的合理选择，驱动装置的合理给螺旋输送机的效率、稳定、安全性的提高都有比较大的作用。尽可能发挥其本有的运输特点，尽可能的减小物料输送的阻力，尽可能不要让物料与螺旋叶片黏结而使输送机失去其输送的能力。本设计阐明了螺旋输送机的工作原理。根据输送量和传输距离确定的螺杆直径，求出所需要的最低螺旋功率，从而根据螺旋功率选择电机、减速器、联轴器。关键词：螺旋输送机；螺旋轴；连续运输IIIAbstractScrewconveyoristheuseofmotordrivenscrewaxisrotation,thespiralpassagematerialssoastorealizethepurposeofmechanicaltransmission,itcanbehorizontal,inclinedorverticaltransmission,suitableforshortdistancetransportation,hastheadvantagesofsimplestructure,compactstructure,coveranareaofanareasmall,easytosealed,convenientoperationandmanagement.Themissionistodesignahorizontalconveyingofwheat,riceandotherkindsoffoodscrewconveyor,thethroughputof30t/h,conveyingdistanceis8meters,insideandoutsideareabletoadaptto.Keyresearchinwiththereasonablechoiceofdrive,drivethereasonableforscrewconveyorintheefficiency,stabilityandsecurityofallhasabiggerrole.Asfaraspossiblethetransportofitscharacteristics,asfaraspossiblethereductionoftheresistanceofthematerialconveying,asfaraspossible,don'tletthematerialandthespiralvanebondandmaketheconveyortoloseitsabilitytodeliver.Thisdesignillustratestheworkingprincipleofscrewconveyor.Accordingtothroughputandtransmissiondistanceofthescrewdiameter,andtheminimumneededtospiralpower,soastochooseaccordingtothespiralpowermotor,reducer,coupling.Keywords:screwconveyor；screwaxis；continuoustransportationIV目录1引言.................................................................................................................11.1课题背景..........................................................................................................11.2课题的构思和思路..........................................................................................11.3螺旋输送机的设备组成..................................................................................11.4螺旋输送机的发展概述..................................................................................21.4.1螺旋输送机的应用范围........................................................................21.4.2螺旋输送机的发展历史........................................................................21.4.3螺旋输送机的研究现状........................................................................21.4.4螺旋输送机的发展趋势........................................................................32螺旋输送机的设计.................................................................................................42.1输送物料的运动分析......................................................................................42.1.1螺旋输送机工作原理............................................................................42.1.2输送物料的运动分析............................................................................42.2螺旋输送机的整体布置..................................................................................62.3螺旋轴及其轴承的设计..................................................................................72.3.1螺旋轴的设计........................................................................................72.3.2叶片的设计..........................................................................................112.3.3螺旋轴的强度校核..............................................................................132.4进出料口的选择............................................................................................152.4.1进料口..................................................................................................152.4.2出料口..................................................................................................153驱动装置的计算选型...........................................................................................173.1电动机的选型................................................................................................173.2减速器的选择................................................................................................184螺旋轴轴承的选择...............................................................................................204.1头部和尾部轴承的选择................................................................................204.2中间吊轴承....................................................................................................214.3轴承的强度校核............................................................................................224.4键的校核........................................................................................................23V5螺旋壳体的设计...................................................................................................245.1螺旋壳体的设计............................................................................................245.2支撑架的设计................................................................................................246结论...............................................................................................................26谢辞....................................................................................................................
