矿用带式输送机结构设计及仿真论文含外文翻译

哈尔滨理工大学学士学位论文-I矿用带式输送机结构设计及仿真摘要带式输送机是一种连续运输机械，也是一种通用机械。带式输送机被广泛应用在港口、电厂、钢铁企业、水泥、粮食以及轻工业的生产线。即可以运送散状物料，也可以运送成件物品。本次设计的矿用带式输送机主要用来承担煤矿井下巷道短距离的煤炭转运任务。设计过程严格遵循带式输送机的一般设计原则。首先对带式输送机作了简单的概述，接着分析了带式输送机的选型原则和计算方法，然后根据输送物料的特性和给定的工作条件确定了带式输送机的整机结构，并对驱动装置和工作部分的主要零部件进行选型计算和强度校核，确定了传动滚筒所需圆周驱动力及皮带的张紧方式、张紧力大小等。普通型带式输送机由六个主要部件组成：驱动装置、工作部分、改向装置、机架、拉紧装置以及输送带。由于井下工作环境恶劣，设备运行工况复杂，所以在设计过程中需要考虑各种可能出现的因素，并计算最危险工况下运输机的各项参数，采取相应措施，为带式输送机正常可靠的运行提供有效保证。关键词带式输送机；井下；主要部件；选型设计哈尔滨理工大学学士学位论文-IIThedesignoftherubberbeltconveyorusedincoalmineAbstractRubberbeltconveyornamedbeltconveyoralsonamedbeltmachine，isacontinuoustransportationmachinery,andisalsoakindofgeneralmachinery.Rubberbeltconveyorarewidelyusedinport,powerplant,steelenterprise,cement,foodandlightindustrialproductionline.Namelycantransportdisper-sestheshapematerial,alsocancarryasarticles.Thebeltconveyordesignedthistimeismainlyusedfortransportingthecoalatashortdistanceinthecoalmineroadwayunderground.Thedesignprocessstrictlyfollowthegeneraldes-ignprinciplesofthebeltconveyor.Atfirst,itisasimpleintroductionaboutthebeltconveyor.Next,itisananalysisofthebeltconveyorselectionprinciplesan-dcalculationmethods.Afterthat,accordingtothematerialfeaturesandworkingconditionsgiven,thewholestructureofthebeltconveyorwasdetermined.Thenitisthecalculationandstrengthcheckingaboutselectingdrivingdeviceandthemaincomponentsintheconveyor.Thecircumferencedrivingforceofthedriveroller、thetensioningtypeandtheamountoftensioningforcewerealsodeter-mined.Theordinarybeltconveyorconsistsofsixmainparts:DriveUnitWork-ingpart、DeliveryEnd、IntermediateStructure、LoopTake-UpandBelt.Asaresultofundergroundworkingenvironmentandthecomplexityofequipmentoperatingconditions,itisnecessarytoconsidereverykindofpossibleworkingconditionsduringitsdesignandcalculatetheparametersinthemostdangerouscondition,takecorrespondingmeasurestoprovideaneffectiveguaranteeforthenormalandreliabletransportofthebeltconveyor.KeywordsRubberbeltconveyorbelt；underground；maincomponents；哈尔滨理工大学学士学位论文-IIIlectotypedesign哈尔滨理工大学学士学位论文-IV目录摘要......................................................................................................................IAbstract...............................................................................................................II第1章绪论........................................................................................................61.1课题背景...................................................................................................61.1.1国外带式输送机技术的发展............................................................61.1.2国内带式输送机技术的发展............................................................71.2设计的目的及意义...................................................................................81.3带式输送机的结构、组成、工作原理和主要特点...............................81.3.1带式输送机的结构和组成................................................................81.3.2带式输送机的工作原理....................................................................81.3.3带式输送机的主要特点....................................................................81.4主要内容...................................................................................................9第2章带式输送机方案设计..........................................................................102.1带式输送机的总体设计.........................................................................102.1.1总体设计方案的确定......................................................................102.1.2设计中的关键问题及解决方法......................................................112.2已知原始数据及工作条件.....................................................................112.3输送带运行速度及其宽度的设计.........................................................122.3.1输送带运行速度的设计..................................................................122.3.2输送带宽度的设计..........................................................................132.4传动滚轮所需圆周驱动力的计算.........................................................142.4.1计算公式..........................................................................................142.4.2主要阻力计算..................................................................................142.4.3附加阻力的计算..............................................................................152.4.4主要特征阻力的计算......................................................................162.4.5附加特征阻力的计算......................................................................162.4.6倾斜阻力的计算..............................................................................172.4.7传动滚筒最大扭矩的计算..............................................................172.5传动功率的计算.....................................................................................172.5.1传动滚筒轴功率的计算..................................................................172.5.2传动滚筒轴的设计与计算..............................................................182.5.3电动机功率的计算..........................................................................192.6输送带张力的计算及拉紧装置拉紧力的计算.....................................202.6.1输送带不打滑条件的校核...........................................................
