摘要斜盘轴向柱塞泵是液压系统中被广泛使的动力元件，用于各类工程机械中。其本身结构的特殊性工作柱塞存在着剩余容积、缸体与柱塞加工修配等相对困难，并且维护成本高、以及缸套加工成本高等问题。针对上述问题进行以下几方面改进；（1）柱塞内放入填充物；（2）在缸孔内加入内套；（3）采用带内圈轴承改善加工条件。通过上述的措施可有效的提高斜盘轴向柱塞泵的容积效率、降低维护成本提高了性能品质、节约缸套加工成本；在上述改进的基础上设计一款额定压力：；额定转速：；额定排量：ml/r的手动伺服变量斜盘轴向柱塞泵，并进行柱塞与滑靴、缸体、斜盘、泵轴的受力分析以及强度校核，结果满足相应的设计要求。关键词轴向柱塞泵斜盘缸体柱塞AbstractWobble-axialpistonpumpisdynamiccomponentswhicharewidelyusedinvariousconstructionmachineryinhydraulicsystem.Becauseitsownspecialstructure、thereisaplungerresidualvolume、processingandfixingofthecylinderplungerarerelativelydifficult,thecostsofmaintainingandtheprocessingofcylinderishighToaddresstheaboveissuescarryingonfollowingaspectsesimprovements:(1)Addcramminginplunger;(2)addinginnersleeveinthecylinderhole;(3)improvetheprocessingconditionswithbearinginnerring.PassageofthesemeasurescaneffectivelyimprovetheWobble-axialpistonpumpvolumetricefficiency,reducethecostsofmaintainingandenhancedthequalityandperformance,savingcylinderprocessingcosts;Inimprovingonthebasisofthedesignpressurerated:;RatedSpeed:;RatedDisplacement:ml/rmanualservovariableaxialpistonpumprampsite,andwiththeplungerSlipper,block,catchbasin,Analysisoftheshaftandstrengthcheck,theresultsmeetsthecorrespondingdesignrequirements.KeywordsAxialpistonpumpSlantingCylinderPlunger目录TOC\o"1-3"\u摘要PAGEREF_Toc171564922\hIAbstractPAGEREF_Toc171564923\hII第1章绪论PAGEREF_Toc171564924\h11.1国内CY系列轴向柱塞泵发展概况PAGEREF_Toc171564925\h11.2国外轴向柱塞泵发展概况PAGEREF_Toc171564926\h21.3CY系列轴向柱塞泵的主要用途和应用领域PAGEREF_Toc171564927\h21.4主要参数PAGEREF_Toc171564928\h3第2章受力分析PAGEREF_Toc171564929\h42.1柱塞与滑靴的受力PAGEREF_Toc171564930\h42.1.1柱塞（包括滑靴）的移动惯性力PAGEREF_Toc171564931\h62.1.2柱塞吸入油液所需的总吸入力PAGEREF_Toc171564932\h82.1.3滑靴支承面所需的总密封力PAGEREF_Toc171564933\h82.1.4柱塞（位于吸入行程）的总摩擦力PAGEREF_Toc171564934\h102.1.5克服滑靴翻转所需的推压力PAGEREF_Toc171564935\h102.1.6压排过程PAGEREF_Toc171564936\h132.1.7处于压排行程柱塞所受的力PAGEREF_Toc171564937\h152.2缸体受力PAGEREF_Toc171
