摘要对双轴直线振动筛进行分析，从整体布局到个别零件的选用都进行了设计，包括筛箱，筛面的设计和固定，激振器的形状，支撑方案等等，还包括轴、偏心块等零件的设计。采用双电机带动使得两个轴上的偏心块同步，另一方面采用了座式结构，淘汰了以往悬挂式的方式，使得结构更加安全，占地面积更小。本产品为生产能力为85.5t/h的中型振动筛，对于筛框的材料有比较高的要求，现采用高强度和高冲击韧性的钢材，不仅仅提高了筛框的耐用度，还减轻了整个结构的重量，对弹簧的选则等许多方面也带来了很多的方便。设计中还包括对连接和固定件的选用，采用十字轴联轴器和轮胎联轴器。并用螺栓连接代替焊接，减小了焊接时应力对它的影响。关键词：振动筛；激振器；偏心块；横梁AbstractThisarticleiscarriedoutmainlyaccordingtothedesignofthetwoaxlevibratingseparatorsofstraightline,fromoveralllayoutgotoindividualelementchoosetogoonimproving,includesiftingthedesignofcaseandcompassscreensurfaceandtheregularshapeofvibrator,supportthedesignofschemeandsoon,stillincludethedesignoftheelementssuchasaxleandpartialpiece.Drivewithdoublegenerator,positivedrivemakestwopartialpiecessynchronous,hasadoptedontheotherhandtousetypestructure,havesupersededthewayofformeroverheadsuspension,makestructuremoresafe,itislesstocoveranareaofarea.Thisdesignproducthashigherrequirement,forthematerialofscreenframeforproductivityisthelargescalevibratingseparatorof80t/h,hasnownotonlyraisedthedurabilityofscreenframewiththehigh-strengthandhighsteelmaterialofimpacttenacity,havestillalleviatedtheweightofentirestructure,forspringchoosetohavealsobroughtmanyconveniences.Indesignstillincludeforconnectionandregularchoosing,withthedurableshaftcouplingofcrossaxle,replaceweldingwithboltconnection,itislittletoreduceweldingstressforit'sinfluence.Keyword:Vibratingseparator;vibrator;partialpiece;beam目录TOC\o"1-5"\h\z\t"标题,6"HYPERLINK\l"_Toc264098407"摘要PAGEREF_Toc264098407\hIHYPERLINK\l"_Toc264098408"AbstractPAGEREF_Toc264098408\hIIHYPERLINK\l"_Toc264098410"第1章绪论PAGEREF_Toc264098410\h1HYPERLINK\l"_Toc264098411"1.1课题研究背景及意义PAGEREF_Toc264098411\h1HYPERLINK\l"_Toc264098412"1.3振动筛在国内外的发展现状PAGEREF_Toc264098412\h3HYPERLINK\l"_Toc264098413"1.4振动筛的工作原理、分类及特点PAGEREF_Toc264098413\h5HYPERLINK\l"_Toc264098414"1.4.1振动筛的工作原理PAGEREF_Toc264098414\h5HYPERLINK\l"_Toc264098414"1.4.2直线振动筛的工作原理6HYPERLINK\l"_To
