I轴向柱塞泵设计摘要液压泵是向液压系统提供一定流量和压力的油液的动力元件，它是每个液压系统中不可缺少的核心元件，合理的选择液压泵对于降低液压系统的能耗、提高系统的效率、降低噪声、改善工作性能和保证系统的可靠工作都十分重要。本次设计对轴向柱塞泵进行了分析，主要分析了轴向柱塞泵的分类，对其中的结构，如柱塞的结构型式、滑靴结构型式、配油盘结构型式等也进行了分析和设计，还包括它们的受力分析与计算。同时缸体的材料选用以及校核也很关键，本文对变量机构分类型式也进行了分析，最后利用Solidworks制图软件绘制零件图与组装成装配图,并进行干涉检验，无误后出图。本文对柱塞泵今后的发展也进行了展望。关键词：轴向，柱塞泵，设计计算，SolidworksIIDESIGNOFAXIALPISTONPUMPABSTRACTHydraulicpumpisthepowercomponentswhichcanProvideacertaindischargeandpressureoftheoilforHydraulicsystem.Itisindispensablecorecomponentsforeachhydraulicsystem.Itisveryimportanttoselectareasonablehydraulicpump,becauseitcaneffectivelyReducetheenergyconsumptionofthehydraulicsystem,improvesystemefficiency,reducenoise,improveperformanceandensurereliableoperationofthesystem.Thisdesignanalysisaxialpistonpump.Itmainlyanalyzedtheclassificationofaxialpistonpump,onwhichthestructure,suchasthestructuretypeoftheplunger,thestructuretypeofslipperandoilpanstructuretypecarriedoutanalyzedanddesigned,includingstressanalysisandcalculationoftheirtoo.Atthesametime,theselectionofmaterialsandcheckingthecylinderisalsocritical,thetypeofvariableinstitutionalclassificationwasalsoanalyzedinthispaper,finally,DrawingpartsdrawingandinstallingAssemblybodyusethedrawingsoftwareofsolidworks,anddrawingthemafterinterferencetesting.Thefuturedevelopmentofpistonwasalsodiscussedinthispaper.KEYWORDS:axial,pistonpump,designandcalculation,solidworksi目录摘要（中文）..............................................................I摘要（英文）.............................................................II1绪论....................................................................i1.1引言...............................................................11.2轴向柱塞泵国内外研究现状与发展方向.................................12直轴式轴向柱塞泵工作原理与性能参数......................................32.1直轴式轴向柱塞泵工作原理...........................................32.2直轴式轴向柱塞泵主要性能参数.......................................42.2.1排量、流量、容积效率与结构参数...............................4222扭矩与机械效率...............................................52.2.3功率与效率...................................................63直轴式轴向柱塞泵运动学及流量品质分析....................................63.1柱塞运动学分析.....................................................63.1.1柱塞行程S...................................................73.1.2柱塞运动速度分析V...........................................73.1.3柱塞运动加速度a..............................................73.2滑靴运动分析.......................................................83.3瞬时流量及脉动品质分析.............................................93.3.1脉动频率....................................................113.3.2脉动率......................................................114柱塞泵主要部件的设计与受力分析.........................................124.1柱塞设计与受力分析................................................124.1.1柱塞结构形式................................................124.1.2柱塞结构尺寸设计............................................124.1.3柱塞受力分析................................................134.2滑靴受力分析与设计................................................164.2.1滑靴受力分析................................................164.2.2滑靴设计....................................................184.2.3滑靴结构型式与结构尺寸设计..................................194.3配油盘受力分析与设计.............................................224.3.1配油盘设计..................................................224.3.2配油盘受力分析..............................................23ii4.3.3验算比压P、比功Pv........................................264.4缸体设计..........................................................274.4.1缸体的稳定性................................................274.4.2缸体主要结构尺寸的确定......................................274.5斜盘力矩分析......................................................294.5.1柱塞液压力矩1M.............................................304.5.2过渡区闭死液压力矩2M.......................................304.5.3回程盘中心预压弹簧力矩3M...................................324.5.4滑靴偏转时的摩擦力矩4M....................................324.5.5柱塞惯性力矩5M.............................................334.5.6柱塞与柱塞腔的摩擦力矩6M...................................334.5.7斜盘支承摩擦力矩7M.........................................334.5.8斜盘与回程盘回转的转动惯性力矩8M..........................334.5.9斜盘自重力矩9M.............................................335柱塞回程机构设计与变量机构.............................................345.1柱塞回程机构设计..................................................345.2变量机构.........................................................356SolidWorks三维制图....................................................366.1Solidworks简介.................................................366.2主要零件三维图与工程图...........................................376.2.1柱塞的三维图与工程图........................................376.2.2滑靴的三维图与工程图........................................376.2.3配油盘的三维图与工程图......................................386.2.4缸体的三维图与工程图........................................396.3轴向柱塞泵的装配体...............................................40结论.....................................................................41参考文献.................................................................42致谢..................................
