毕业设计说明书题目名称：一种轴向柱塞泵的结构设计及其造型院系名称：机电学院班级：机自XX学号：XXXXXXXXXXXXX学生姓名：XXXXXXX指导教师：XXXXXX2012年6月中原工学院毕业设计（论文）1摘要斜盘式轴向柱塞泵是液压系统中的主要部件，它是靠柱塞在柱塞腔内的往复运动，改变柱塞腔内容积实现吸油和排油的，是容积式液压泵。对于斜盘式轴向柱塞泵，柱塞、滑靴、配油盘、缸体是其重要部分。柱塞是其主要受力零件之一；滑靴是高压柱塞泵常采用的形式之一，它能适应高压力高转速的需要；配油盘与缸体直接影响泵的效率和寿命。由于配油盘与缸体、滑靴与柱塞这两对高速运动副均采用了一静压支承，省去了大容量止推轴承，因此它具有结构紧凑、零件少、工艺性好、成本低、体积小、重量轻、比径向泵结构简单等优点。由于斜盘式轴向柱塞泵容易实现无级变量、维修方便等优点，因而斜盘式轴向柱塞泵在技术经济指标上占很大优势。关键词:斜盘,柱塞泵,轴向中原工学院毕业设计（论文）2AnaxialpistonpumpstructuredesignandmodellingABSRACTTheinclineddishtypeandaxialpumpwithapillarisamainpartinliquidpresssystem，Theinclineddishtypeandaxialpumpwithapillarisabackandforthmovementbypillartofilltheinsideofthepillarcavity，inordertochangethepillarfillsthecontentsofcavitytorealizetheoilofinhalingwithlineupoily，Isacapacitytypeliquidtopressthepump.Filltopillartopumpfortheinclineddishtypestalkthepillarfill,slipthebootsandgotogetherwiththeoildishanisitsimportancepart.Thepillarfillsisitsuffertheoneofthedintsparepartsprimarily.Theslipperybootsisoneoftheformthathighpressurepillarfillthepumptooftenadopt.Itcanadapttothehighdemandturningsooninhighpressuredint,gotogetherwiththeoildishandtheefficiencyofthedirectinfluenceinapumpwithlifespan.Becauseofgoingtogetherwiththeoildishfills,pillarandaslipperybootsthesetworightnessofhighspeedsthesportthevice-alladoptingathestaticpressureaccepts.Theprovincewenttothebigcapacitypushthebearings,havetheconstructiontightlypacked,thesparepartsislittle,thecraftisgood,thecostislow,thephysicalvolumeissmall,theweightislight,comparingthepathfacetopumptheconstructionsimpleetc.Becausetheinclineddishtypestalkfillstopillarthepumptorealizestohavenoeasilytheclasschangesthedeal,maintainconvenienceandsoon.Keywords：TheInclinedDishPillarPumpAxialPump中原工学院毕业设计（论文）3目录摘要..................................................................................................................................................1ABSRACT........................................................................................................................................2前言..................................................................................................................................................41直轴式轴向柱塞泵工作原理与性能参数.................................................................................61.1直轴式轴向柱塞泵工作原理.........................................................................................61.2直轴式轴向柱塞泵主要性能参数.................................................................................61.2.1排量、流量、容积效率与结构参数.................................................................71.2.2扭矩与机械效率.................................................................................................81.2.3功率与效率.........................................................................................................82直轴式轴向柱塞泵运动学及流量品质分析...........................................................................102.1柱塞运动学分析...........................................................................................................102.1.1柱塞行程S......................................................................................................102.1.2柱塞运动速度分析V.......................................................................................112.1.3柱塞运动加速度a............................................................................................112.2滑靴运动分析...............................................................................................................122.3瞬时流量及脉动品质分析...........................................................................................132.3.1脉动频率.............................................................................................................142.3.2脉动率.................................................................................................................143柱塞泵主要部件的设计与受力分析.......................................................................................163.1柱塞设计与受力分析...................................................................................................163.1.1柱塞结构形式...................................................................................................163.1.2柱塞结构尺寸设计...........................................................................................163.1.3柱塞受力分析....................................................................................................173.2滑靴设计.......................................................................................................................203.2.1滑靴设计常用剩余压紧力法...........................................................................203.2.2滑靴结构型式与结构尺寸设计.......................................................................213.3配油盘受力分析与设计...............................................................................................233.3.1配油盘设计.......................................................................................................233.3.2配油盘受力分析...............................................................................................253.3.3验算比压P、比功P
