2YAH1548型圆振动筛设计说明书

I2YAH1548型圆振动筛设计摘要：目前我国各种选煤厂使用的设备中,振动筛是问题较多、维修量较大的设备之一。这些问题突出表现在筛箱断梁、裂帮,稀油润滑的箱式振动器漏油、齿轮打齿、轴承温升过高、噪声大等问题,同时伴有传动带跳带断带等故障。这类问题直接影响了振动筛的使用寿命,严重影响了生产。2YAH1548型圆振动筛可以很好的解决此类问题，因此本次设计的振动筛为2YAH1548型圆振动筛，该系列振动筛主要用于煤炭行业中物料分级、脱水、脱泥、脱介等作业。其工作可靠，筛分效率高，但设备自身较重。设计分析论述了设计方案，包括振动筛的分类与特点和设计方案的确定；对物料的运动分析，对振动筛的动力学分析及动力学参数的计算，合理设计振动筛的结构尺寸；进行了激振器的偏心块等设计与计算，包括原始的设计参数，电动机的设计与校核；进行了主要零部件的设计与计算，皮带的设计计算与校核，弹簧的设计计算，轴的强度计算，轴承的选择与计算，然后进行了设备维修、安装、润滑及密封的设计，最后进行了振动筛的环保以及经济分析。关键词：振动筛；激振器；圆振动筛II2YAH1548-roundgoodshakerdesignAbstract:Atpresent,China'scoalpreparationplantalltheequipmentusedintheshakerismoreproblems,maintenanceofoneofthelargerequipment.Theseissuesinsieveoutstandingperformancemeoffbeam,crackhelp,lubricationoildilutethebox-typevibratoroilspills,fightingtoothgear,bearingtemperaturerisetoohigh,majorissuessuchasnoise,accompaniedbydancingwithbrokenbelts,suchasfaultzone.Suchissuesdirectlyaffectingthelifeoftheshaker,whichhasseriouslyaffectedtheproduction.2YAH1548-roundgoodshakercansolvesuchproblems,sothisshakerdesignedforround2YAH1548-shaker,theseriesofmajorshakerinthematerialsusedinthecoalindustryclassification,dehydration,desliming,suchasreferralsfromOperations.Itsreliable,efficientscreening,buttheirheavyequipment.Designanalysisonthedesignoptions,includingtheclassificationandshakerfeaturesanddesignprogrammestobeconfirmed;materialsonthemovementoftheshakerandthedynamicsoftheparameters,todesignthestructureofvibratingscreensize;conductTheeccentricblockoftheexciter,suchasdesignandcalculation,includingtheoriginaldesignparameters,motordesignandverification;werethemaincomponentsofthedesignandcalculation,beltsandcheckthedesignandcalculation,thedesignofspring,theaxisofStrength,thechoiceofbearingsandcalculationandthenproceedtothemaintenanceofequipment,installation,lubricationandsealthedesign,ashakerfinalenvironmentalandeconomicanalysis.Keywords:shaker;Vibrator;roundshaker目录摘要.............................................................................错误!未定义书签。Abstract.......................................................................错误!未定义书签。1绪论.........................................................................................................11.1前言..................................................................................................11.2背景..................................................................................................11.2.1振动筛的发展概况....................................................................11.2.2我国振动筛的发展概况.............................................................21.3振动筛的分类....................................................................................31.4筛分机械发展方向.............................................................................42振动筛筛面物料运动理论.....................................................................52.1筛上物料的运动分析..........................................................................52.2正向滑动...........................................................................................62.3反向滑动...........................................................................................72.4跳动条件的确定................................................................................72.5物料颗粒跳动平均运动速度...............................................................83.振动筛的工作原理及结构组成...........................................................103.1圆振动筛的工作原理........................................................................103.2振动筛基本结构..............................................................................103.2.1筛箱.......................................................................................103.2.2激振器...................................................................................103.2.3支承装置和隔振装置..............................................................103.2.4传动装置...............................................................................104.振动筛动力学基本理论.......................................................................115.振动筛参数计算...................................................................................155.1运动学参数的确定...........................................................................155.2振动筛工艺参数的确定....................................................................165.3动力学参数.....................................................................................175.4电动机的选择..................................................................................175.4.1电动机功率计算.....................................................................175.4.2选择电机................................................................................185.4.3电机的启动条件的校核...........................................................186主要零件的设计与计算.......................................................................206.1轴承的选择与计算...........................................................................206.1.1轴承的选择............................................................................206.1.2轴承的寿命计算.....................................................................206.2皮带的设计...........
