兰州交通大学毕业设计(论文)I摘要液压泵是随着液压传动技术的产生而产生的,随着我国工业和科学技术的不断发展,机、电、液一体化在整个机械行业所占的比重越来越大,液压传动技术在诸多领域得到了越来越广泛的应用,因此,液压泵作为动力元件成为液压传动元件中不可缺少的一部分,起到非常重要的作用,同时越来越受人们的关注。单作用叶片泵作为液压泵的一种,在液压传动系统中有较为广泛的应用。基于单作用叶片泵的应用范围和优缺点,本文主要对单作用叶片泵做了从结构设计到部分结构性能分析的工作。其主要过程是通过现有工况确定单作用叶片泵主要的零件尺寸,然后通过SolidWorks软件对单作用叶片泵进行三维实体建模和虚拟装配。再对装配体中叶片的运动进行运动学分析和装配体进行动力学分析,最后对转子的静态应力进行有限元分析。整篇论文对于单作用叶片泵的设计具有参考和实用意义,同时也对单作用叶片泵的优化具有一定的指导作用。关键字:单作用叶片泵,有限元,优化设计兰州交通大学毕业设计(论文)IIAbstractHydraulicpumpisproducedwithhydraulictransmissiontechnology,Withthecontinuousdevelopmentofindustryandscienceandtechnologyinourcountry,machine,andelectric,iquidintegrationinthroughoutmachineryindustrybyaccountedforofshareincreasinglybig.Hydraulicdrivetechnologygethasincreasinglywidelyofapplicationinmanyarea.Sohydraulicpumpaspowercomponentsbecamehydraulicdrivecomponentsinthenotmissingofpart,uptoveryimportantofrole,whileincreasinglybypeopleofconcern.Single-actingvanepumpasahydraulicpump.Thereareusedinhydraulictransmissionsystemmoreandmore.Basedonthescopeofapplicationofthesingle-actingvanepumpandtheadvantagesanddisadvantages.Thisarticlefocusesonsingle-actingvanepumppartmadefromstructuraldesigntostructuralanalysis.Itsmainprocessesaredeterminedbyexistingconditionsofsingle-actingvanepumppartsdimensio.ThroughSolidWorkssoftwareforsingle-actingvanepumpforthree-dimensionsolidmodeling,andvirtualAssembly.AssemblyblademotioninkinematicsanalysisandAssemblydynamicsanalysis,staticfiniteelementanalysisofthestressofthelastrotor.Papersforthedesignofsingle-actingvanepumpwithreferencesandpracticalsignificance,aswellasoptimizationofsingle-actingvanepumpcapableofguiding.Keywords:single-actingvanepump;finite;optimaldesign兰州交通大学毕业设计(论文)III目录摘要.............................................................................................................................................IAbstract......................................................................................................................................II目录..........................................................................................................................................III1绪论......................................................................................................................................11.1课题研究背景..............................................................................................................11.1.1CAD技术的发展................................................................................................11.1.2SolidWorks软件简介.........................................................................................11.1.3单作用叶片泵简介............................................................................................31.2课题研究的目的与意义..............................................................................................41.3课题研究的内容..........................................................................................................52单作用叶片泵结构的设计及尺寸参数的初定..................................................................62.1单作用叶片泵结构的设计..........................................................................................62.1.1单作用叶片泵的计算中用到的主要技术参数................................................62.1.2确定单作用叶片泵的工况................................................................................62.1.3被设计的单作用叶片泵的结构分析................................................................72.1.4确定单作用叶片泵的结构................................................................................72.1.5确定单作用叶片泵的参数................................................................................72.2单作用叶片泵的零件尺寸的初定..............................................................................82.2.1配油装置尺寸的确定........................................................................................82.2.2轴尺寸的初步确定............................................................................................92.2.3轴承的选取......................................................................................................102.2.4轴的受力分析及校核......................................................................................102.2.5轴承寿命的校核...............................................................................................122.2.6压力调节端零件尺寸的确定...........................................................................133单作用叶片泵零件的三维实体建模................................................................................153.1箱体类零件建模.........................................................................................................153.2调流量端零件的建模................................................................................................173.3定子环定位端零件的建模........................................................................................183.4配油零件的建模........................................................................................................204单作用叶片泵的虚拟装配................................................................................................224.1配油装置的装配..........................................................
