长距离矿用皮带输送机总体设计

I摘要本设计是长距离矿用皮带输送机总体设计。长距离皮带输送机可实现在长距离运输巷道内连续的、大运量的运输，减少能源损耗，节约成本，同时提高生产效率。在设计中首先根据运输巷道的布置图提出并确定设计方案。其次根据原始参数进行皮带输送机总体的设计：确定带宽；计算输送机总圆周驱动力；计算输送机各点的张力并确定圆周驱动力的分配；电动机装机功率的计算及确定电动机布置方案；输送机的拉紧力及拉紧行程的计算。最后对主要传动部件进行设计：减速器的设计计算及托辊的校核。本设计主要应用于运输巷道，主要的特点为长距离、大运量。解决了在长距离的情况下输送机多点驱动的问题，以及长距离皮带拉紧的问题。关键词：长距离输送机；张力计算；减速器设计IIAbstractThisdesignisthelong-distancebeltconveyorforminedesign.Throughtheconveyorbelttoachievetheoveralldesignofroadwayinthelong-distancetransportcontinuous,largecapacityoftransport,reducingenergyconsumption,savingcostswhileincreasingproductivity.Firstofall,inthedesignlayoutoftheroadwayundertheproposedtransportanddeterminethedesign.Second,accordingtotheoriginalparametersoftheoveralldesignofbeltconveyor:identificationbandwidth;calculatedthetotalcircumferenceofconveyordrive;calculatethepointsoftensionconveyoranddeterminethecircumferenceofthedrivingforcedistribution;motorinstalledpowerofcalculationanddeterminetheelectricallayoutoftheprogram;deliveryMachinetensionforceandtensioncalculationtrip.Finally,thedesignofthemaintransmissioncomponents:speedreducerdesigncalculationsandcheckidlers.Thisdesignismainlyusedinthetransporttunnel,themainfeaturesofthelong-distance,largecapacity.Solvedinthecaseoflongdistancemulti-pointdriveconveyor,aswellaslong-distancebelttensionerproblem.Keywords:Longdistanceconveyor;tensioncalculation;reducerdesignIII目录摘要.....................................................................................................................IAbstract................................................................................................................II第1章绪论........................................................................................................11.1国内外带式输送机的发展现状...........................................................11.2带式输送机的分类...............................................................................21.3选题的目的、意义和本文主要的研究内容........................................31.4设计目标及原始参数...........................................................................4第2章输送机总体结构设计计算....................................................................52.1输送机总体方案确定..........................................................................52.2输送带张力计算...................................................................................62.2.1输送带允许最大的下垂度计算最小张力.................................62.2.2输送带不打滑条件....................................................................72.2.3各种驱动力分配情况下各点张力计算.....................................92.3输送机的基本功能参数.....................................................................132.3.1输送带的宽度及校核..............................................................132.3.2输送带层数的计算..................................................................162.3.3输送带强度的校核..................................................................172.3.4输送带最大的物料横截面积..................................................192.3.5总圆周驱动力计算..................................................................202.4电动机功率计算及布置方案.............................................................252.5液压拉紧装置的原件选择和计算.....................................................262.5.1拉紧力和拉紧行程的计算......................................................262.5.2拉紧行程的确定......................................................................26第3章主要传动部件设计..............................................................................283.1减速器设计.........................................................................................283.1.1传动比的分配和传动效率的选择..........................................283.1.2传动装置的运动和动力参数计算..........................................293.1.3齿轮传动设计..........................................................................31IV3.1.4轴的设计..................................................................................413.1.5键的选择和校核......................................................................513.1.6滚动轴承的选择与校核..........................................................513.2托辊的校核.........................................................................................533.2.1校核辊子载荷..........................................................................543.2.2托辊的额定负荷和最大转速..................................................553.3其它设备的选型.................................................................................563.3.1滚筒的选择..............................................................................563.3.2导料槽及清扫器选型..............................................................573.3.3制动及逆止装置......................................................................573.3.4保护设备与其他辅助设备选型..............................................58第4章经济与技术分析..................................................................................58结论..................................................................................................................59致谢..................................................................................................................60参考文献............................................................................
