滚筒输送机设计说明书

摘要滚筒输送机是现代最主要的散状物料输送设备之一。滚筒是滚筒输送机的主要传部件，它的作用有两个：一是传递动力，二是改变输送带运行方向。滚筒输送机滚筒的设计质量，关系到整个输送机系统的性能、安全性和可靠性。目前，国内滚筒的设计一般采用近似公式，对于中小型滚筒已经能够满足工程需求，但对于大型滚筒这种设计方法其结果与工程实际有一定的差距，它的安全性和可靠性难以保障。由于缺乏精确的计算方法，如果盲目的增大安全系数，会使结构尺寸变大，重量增加，强度得不到显著的提高同时又增加了成本。本设计简要介绍了辊子输送机的作用，在对辊子输送机特点和形式了解之后，对辊子输送机总体方案进行设计。总体方案确定后是各个零部件的设计，重点对辊子输送机的主要参数、链传动牵引力理论计算、辊子间距、辊子直径、支撑架、脚、轴承等零件进行设计，选择合适的动力源和合适的传动系统及速度控制系统，为合理地设计辊子输送机提供了依据。在总体方案和个零件的参数确定后，应用Pro/E软件对个零件建模和运动仿真。关键字：作用；主要参数；设计；建模；仿真AbstractRollerconveyoristhemainequipmentofbulkmaterialconveying.Thedrumisthemaintransmissionpartinrollerconveyor,ithastwofunctions:oneistotransferpower,thetwoistochangetherunningdirectionoftheconveyingbelt.Thedesignqualityofrollerconveyorroller,relatedtotheperformance,securityandreliabilityofthewholeconveyorsystem.Atpresent,thedomesticrollerdesigngeneraluseoftheapproximateformula,forsmallandmedium-sizedrollerhasbeenabletomeettheengineeringrequirements,butforlargedrumthedesignmethodandtheresultsandengineeringpracticehaveacertaingap,itssecurityandreliabilityaredifficulttoguarantee.Duetothelackofaccuratecalculationmethod,ifblindlyincreasesafetycoefficient,makethestructuresize,weight,strengthcannotbeimprovedsignificantlyandincreasethecostof.Thisdesignintroducetherollerconveyorbriefly.Afterknowaboutcharacteristicsandformofrollerconveyor,designtheoverallschemeofrollerconveyor.Itisthedesignofvariouscomponentsaftertheoverallschemeisgiven.Focusingonthedesigningofthemainparameter,chaindrivetractiontheoreticalcalculations,rollerspacing,rollerdiameter,cage,feet,bearingsandotherpartsofrollerconveyor,selecttheappropriatepowersourceandasuitabletransmissionandspeedcontrolsystems,inoldertoprovidethebasisfortherationaldesignofrollerconveyor.Aftertheoverallprogramandparameteraredetermined,then,inapplicationthesofterofPro/Etobuildtheconstructionofthree-dimensionalmodelandmotionsimulation.Keyword:effect;mainparameters;design;modeling;simulation目录摘要............................................................................................................................................1Abstract........................................................................................................................................2目录..............................................................................................................................................3第一章绪论.............................................................................................................................61.1现代辊子输送机的运行特性.......................................................................................61.2现代辊子输送机的技术水平.......................................................................................61.3电动辊子研制成功.......................................................................................................71.4辊子机架的新发展.......................................................................................................71.5选题的背景：...............................................................................................................81.6选题意义：...................................................................................................................8第二章总体方案的设计............................................................................................................92.1辊子输送机特点及应用范围.......................................................................................92.2结构形式.......................................................................................................................92.3传动方式的选择.........................................................................................................102.3.1链传动...............................................................................................................102.3.2带传动...............................................................................................................102.3.3齿轮传动...........................................................................................................102.4输出方式的选择..........................................................................................................102.4.1动力式辊子输送机..........................................................................................102.4.2限力式辊子输送机..........................................................................................112.4.3触点控制式辊子输送机..................................................................................112.5辊子形式的选择.........................................................................................................112.5.1圆柱形辊子输送机..........................................................................................112.5.2圆锥形辊子输送机..........................................................................................112.5.3轮形辊子输送机..............................................................................................112.6辊子支撑方式的选择..................................................................................................122.6.1定轴式辊子输送机........................................
