I摘要振動篩的研究不斷地向著標準化、系列化、通用化發展，并引入現代化設計手段，采用新材料、新技術、新工藝，其目的在于不斷擴大篩機應用領域，滿足國民經濟建設發展的需要，并擔當對外出口的任務。本文所設計的振動篩的篩分物料為球磨機產品。該產品的大小不是很平均，為了做出更符合要求的物料就需要用振動篩來將球磨機產品進一步細分，將不符合要求的物料重新用球磨機磨小。經過這樣的反復處理最終將物料全部做成符合要求的產品。本課題的振動篩為自同步雙振動電機驅動的，其特點是結構簡單、安裝方便、成本低、容易操作及維護等。其篩箱為板梁鉚焊組合結構，由主副側板、管梁、入料擋板、出料板、篩板等組成，側板選用低合金壓力容器鋼板，強度高、可焊性好，周邊折彎，并在振動方向及沿縱向連接多根角鋼，使側板剛度大大增強，有利于強度的提高和噪音的降低。管梁由法蘭盤、無縫鋼管、加強槽鋼等組成，重量輕、強度大，便于制造安裝，具有互換性。加強槽鋼上有T形孔，使用T形螺栓，便于篩板的安裝維護，消除U形螺栓對管梁的磨損。工作原理：兩臺振動電機的型號相同，可以產生一種組合的直線振動。這種振動可以使輸送槽體中的物料運動，并與篩面發生碰撞，使小于篩孔的物料透過，從而實現物料的幾何分級，實現篩分。總體方案為：采用普通篩分法，振動形式為共振，運動軌跡為直線運動，激振方式為慣性式，隔振方式為一級隔振，隔振彈簧為金屬螺旋式隔振彈簧。關鍵詞：振動篩；篩箱；振動電機IIAbstractTheshakerresearchunceasinglytothestandardization,theseriation,theuniversalizeddevelopment,andtheintroductionmodernizationdesignmethod,usesthenewmaterial,thenewtechnology,thenewcraft,itsgoalliesinunceasinglyexpandsthesievemachineapplicationdomain,satisfiesnationaleconomyconstructiontheneedtodevelop,andtakesontheforeignexportationtheduty.Finallycompletelymakesaftersuchrepeatedlyprocessingthematerialltalliestherequestproduct.Thistopicshakerforself-synchronizingpairvibrationmotor-driven,Itscharacteristicisthestructuresimple,theinstallsconvenient,thecostlow,iseasytooperateandthemaintenanceandsoon.Itsievestheboxisboardcrossbeamrivetinghitchweldsbuilt-upsection,Byhostvice-sidebar,Hollowbeam,Entersthematerialbackplate,Leavesmaterialboard,Sievesboardandsooncomposition,Thesidebarselectsthelow-alloypressurevesselsteelplate,Theintensityishigh,Theweldabilityisgood,Peripheralkneebend,Andinthevibrationdirectionandalonglongitudinalconnectsthemulti-rootsanglesteel,Causesthesidebarrigiditybigenhancement,Isadvantageoustotheintensityenhancementandnoisereducing.Hollowbeambyflangeplate,Seamlesssteelpipe,Strengthenscompositionandsoonchannelsteel,Theweightlight,theintensityisbig,isadvantageousforthemanufactureinstallment,Hastheinterchangeability.StrengthensinthechannelsteeltohavetheTshapehole,UsestheTshapebolt,Isadvantageousforscreenboardinstallsthemaintenance,EliminatestheUshapebolttothehollowbeamattrition.Principleofwork:Twovibratetheelectricalmachinerythemodeltobesame,Mayhaveonekindofcombinationstraight-lineoscillation.Thiskindofvibrationmaycauseinthetransportationtroughbodythematerialmovement,Andhasthecollisionwiththescreeningsurface,Andhasthecollisionwiththescreeningsurface,Thusrealizationmaterialgeometrygraduation,Realizationscreening.Theoverallplanis:Usestheordinaryscreeninglaw,Thevibrationformforresonates,Thepathisthetranslation,Stirsupthestrengthvibrationthewayistheinertiatype,Thevibrationisolationwayislevelofvibrationisolations,Thevibrationisolationspringisthemetalscrewtypevibrationisolationspring。Keywords:thevibrationscreen；theboxscreen；thevibrationelectricmachineryIII目錄摘要.IAbstract.II第1章概述.11.1國內外現狀.11.2振動機械的用途和分類.11.2.1振動機械的組成.21.2.2振動機械的特點.21.2.4振動機械的分類.3第2章主要問題及解決方案.52.1振動篩降噪措施.52.2常見故障及處理措施.52.2.1篩分時篩子不下料或下料不暢.52.2.2篩框斷裂根.52.2.3軸承過熱.52.2.4篩分的分級(根據篩分的目的).6第3章直線振動細篩的結構、工作原理及總體方案的比較確定.73.1結構及工作原理.73.2直線型振動細篩的特點.73.3各類篩分方法的比較確定.83.3.1普通篩分方法.83.3.2概率篩分方法.93.3.3等厚篩分法.93.3.4概率等厚篩分法.103.3.5篩分方法的確定.103.4振動形式的確定.103.4.1非共振篩.103.4.2共振篩.103.5運動軌跡的確定.103.5.1圓運動軌跡.103.5.2直線運動軌跡.113.6激振方式的比較.113.6.1彈性連桿式.113.6.2電磁式.11IV3.6.3慣性式.123.6.4激振方式的確定.12第4章其它零部件的選擇.134.1隔振系統的選擇.134.2篩箱及篩面.134.2.1篩箱.134.2.2篩面的比較選擇.144.2.3篩面的壓緊裝置.154.3支撐裝置的選擇.15第5章各部分設計計算.175.1運動學參數
