济南大学泉城学院毕业设计题目板式输送机的设计专业机械设计制造及其自动化班级学生学号指导教师二〇一二年五月二十八日济南大学泉城学院毕业设计I摘要本次设计的主要内容是鳞板式输送机的结构、传动等内容。鳞板式输送机是链板式输送机的一种，在采矿业、采煤业、货物运输等行业有着广泛的运用。本次设计主要是是在鳞板式输送机的结构构成、输送方式上进行改进和创新。在探索创新思路的可行性时，采用了验证假设的方法。首先假定一个传动（或其他方面）方案，然后根据已知工况和相关的材料，校核各个零部件的强度、刚度等内容是否在允许的范围内，由此进一步把各零件的尺寸合理化。经过探索和对其他资料的研究，对于鳞板式输送机，在其传动方案、张紧方式、润滑方式、零部件尺寸的选择等各个方面有了一个明确、清晰的方案。传动方案：本设计采用滚子链传动，滚子链的形式为单排双边链条。通过计算和检验，得出使用的传动滚子链为非标准，节距P=320mm的滚子链。其他链条的相关尺寸在接下来的设计计算中具体呈现。张紧方案：张紧装置根据链传动的特点，选择螺旋丝杠张紧方式。通过合理布局，张紧装置安放在尾节装置机架两端。零部件的尺寸计算将在接下来的设计计算环节会一一详细的阐述。此设计在传动的稳定性、张紧的有效性、材料的利用上有明显的改进。关键词：鳞板式输送机；传动；张紧装置；滚子链济南大学泉城学院毕业设计IIAbstractThedesignofthemainscalesslatconveyorstructure,transmission,etc.Thescalesslatconveyormachinechainslatconveyorofa,widelyusedinmining,coalmining,cargotransportationandotherindustries.Thedesignofscalesplateconveyorstructure,transportationmethodsforimprovementandinnovation.Explorethefeasibilityofinnovativeideas,verifyassumptions.First,assumethatadrive(orother)programs,Thenaccordingtotheknownconditionsandrelatedmaterials，Checkwithinthevariouscomponentsofstrength,stiffnessinthepermittedrange,Whichfurtherrationalizationofthesizeofthevariousparts.Afterexplorationandotherinformation,ConveyorscalesPlate,Initstransmissionscheme,thewayoftension,lubrication,partssizeselectionwithaclear,clearsolution.Transmissionscheme:Thisdesignusesarollerchaindrive.Therollerchainintheformofasinglerowofbilateralchain.Bycalculatingandtesting,Obtainedusingthetransmissionrollerchainfornon-standard,PitchP=320mmrollerchain.Otherchainsizeinthedesignandcalculationofthenextspecificrendering.Tensionprogram:Thetensioningdeviceaccordingtothecharacteristicsofthechaindrive,Helicalscrewtensionmanner.Adoptionoftherationaldistribution,Tensioningdeviceplacedinbothendsofthetailsectionofthedevicerack.Partsofthesizeofthecalculationwillbedescribedindetailinthenextdesigncalculationslink.Thisdesigninthestabilityofthedrive,tensioningtheeffectivenessoftheuseofmaterialsmarkedimprovement.Keywords：Scalesplateconveyor;Transmission;Tensioningdevice;RollerChain济南大学泉城学院毕业设计1目录摘要........................................................................................................................IABSTRACT..................................................................................................................II1前言............................................................................................................................11.1输送机的概况.....................................................................................................11.1.1输送机的发展历程........................................................................................11.1.2对未来输送机的展望....................................................................................11.2鳞板式输送机......................................................................................................21.3设计时采用的方法及辅助工具..........................................................................31.3.1设计方法........................................................................................................31.3.2设计采用的辅助工具....................................................................................32鳞板式输送机的工作原理和特点............................................................................42.1鳞板式输送机的适用范围和特点......................................................................42.1.1鳞板式输送机的适用范围及组成................................................................42.1.2鳞板式输送机的特点....................................................................................42.2主要结构..............................................................................................................42.2.1鳞板式输送机的结构及示意图....................................................................42.2.2设计的鳞板式输送机的技术与安装要求....................................................53鳞板式送机的设计....................................................................................................63.1引言......................................................................................................................63.2电动机、减速器的选择......................................................................................73.2.1电动机的选择................................................................................................73.2.2减速器的选择................................................................................................83.3链条的计算..........................................................................................................93.3.1链的失效形式................................................................................................93.3.2链传动的承载能力......................................................................................113.3.3确定计算功率..............................................................................................123.3.4选择链条......................................................................................................143.3.5鳞板宽度计算..............................................................................................143.3.6计算链轮转速....................
