斜盘式轴向柱塞泵设计

1摘要现代液压传动中，柱塞泵是使用最广的液压动力元件之一，其性能好坏是影响液压系统工作性能的关键。相对于日益提高的高压、大流量、高功率密度、高集成度、多样的控制形式等要求，我国的柱塞泵设计和制造已远远落后于世界先进水平。本论文在详细分析国内外轴向柱塞泵结构类型及其特点的基础上，设计了一种斜盘式轴向柱塞泵，结构紧凑合理、变量控制灵活多样、集成性好。完成斜盘式轴向柱塞泵总装图及主要零件图，并利用三维软件Pro/E进行三维建模，用UG完成指定零件加工仿真及数控编程。对今后进行轴向柱塞泵的研究和设计具有较高的参考价值。关键词：斜盘式轴向柱塞泵；加工仿真；UG2AbstractModernhydraulictransmission,pistonpumpisthemostwidelyusedinhydrauliccomponents,itsperformanceisoneofthehydraulicsystemistheeffectofthekeyworkperformance.Relativetotherisinghighpressure,bigflow,highpowerdensity,highlevelofintegration,variouscontrolrequirements,ourformofpistonpumpdesignandmanufacturinghaslagsbehindtheworldadvancedlevel.Thisthesisondetailedanalysisofdomesticandinternationalaxialpistonpumpstructurebasedonthetypesandcharacteristics,designakindofswash-plateaxialpistonpump,compactstructure,variablecontrolagilediversity,integration.Completeswash-plateaxialpistonpumpassemblyfigureandmainpartsgraph,andusingthree-dimensionalsoftwarePro/E3-dmodeling,completewithUGdesignatedpartsprocessingsimulationandCNCprogramming.Inaxialpistonpumpresearchanddesignisofhighreferencevalue.Keywords:swash-plateaxialpistonpump;Machiningsimulation;UG3目录摘要........................................................................................................................................1Abstract................................................................................................................................2第1章前言..........................................................................................................................11.1课题背景.................................................................................................................11.2液压技术发展历史.................................................................................................11.3课题提出的意义....................................................................................................21.4国内外研究开发水平及发展趋势........................................................................2第2章斜盘式轴向柱塞泵设计方案..................................................................................52.1液压泵的原理与分类............................................................................................52.1.1液压泵的传动和工作原理.........................................................................52.1.2液压泵的分类............................................................................................62.2斜盘式轴向柱塞泵主体设计方案的确定............................................................62.2.1斜盘式轴向柱塞泵的的基本分类及其特点............................................62.2.2主体设计方案的确定.................................................................................82.3斜盘式轴向柱塞泵的性能参数............................................................................82.3.1压力p（单位Pa）....................................................................................82.3.2排量和流量................................................................................................82.3.3功率和效率................................................................................................92.4斜盘式轴向柱塞泵的工作原理...........................................................................10第3章斜盘式轴向柱塞泵基本设计及计算....................................................................133.1斜盘泵柱塞回程机构的基本设计.......................................................................133.2整体基本结构选定...............................................................................................143.3柱塞泵的主要技术指标及设计计算...................................................................153.3.1柱塞泵主要参数.......................................................................................153.3.2柱塞的直径、行程及理论与实际排量的计算......................................153.3.3配流盘的设计计算...................................................................................163.3.4滑靴的设计计算......................................................错误！未定义书签。3.3.5泵的容积效率分析..................................................错误！未定义书签。3.3.6缸体计算和柱塞强度计算......................................错误！未定义书签。3.3.7定心弹簧计算..........................................................错误！未定义书签。3.3.8传动轴计算..............................................................错误！未定义书签。3.3.9轴承（7008C）寿命计算中心................................错误！未定义书签。3.3.10手动变量机耕的设计计算....................................错误！未定义书签。3.4泵的噪音来源与改进...........................................................错误！未定义书签。3.4.1噪音来源分类..........................................................错误！未定义书签。3.4.2摩擦副的影响因素.................................................错误！未定义书签。3.4.3零件材料的选择......................................................错误！未定义书签。3.4.4引发摩擦副噪声的原因.........................................错误！未定义书签。3.4.5怎样减小摩擦来降低噪声.....................................错误！未定义书签。第四章零部件的加工仿真................................................................错误！未定义书签。4.1NXCAM简介...........................................................................错误！未定义书签。4.2CAM与CAD关系...................................................................错误！未定义书签。44.3NX6.0CAM编程步骤................................................
