摘要-I-摘要齿轮轴零件的主要作用是支撑回转零件、实现回转运动并传递转矩和动力。齿轮轴具备传动效率高、结构紧凑和使用寿命长等一系列优点，是通用机械特别是工程机械传动中的重要零件之一。齿轮轴加工材料、热处理方式、机械加工工艺过程的优化，将对提高齿轮轴的加工质量及寿命有着重要借鉴意义。本设计首先分析了齿轮轴零件的作用和零件的材料，之后把加工传动齿轮轴所用的材料和生产类型确定下来。然后确定毛坯的种类，绘制铸件零件图。接下来设计零件的加工工艺性，包括零件表面的加工方法及热处理方法等。最后进行工艺规程设计，选定加工所用的机床，刀具，夹具等。齿轮轴零件的机械综合性能要求较高，一般选择锻件作为毛坯。合理安排工艺路线，划分加工阶段对保证零件加工质量至关重要.关键词:齿轮轴；工艺分析；工艺规程设计Abstract-II-AbstractThemainfunctionofthegearshaftistosupportrotatingparts,achieverotarymotionandtransfertorqueandpower.Gearshafthasaseriesofadvantages,suchashightransmissionefficiency,compactstructure,longservicelifeandsoon.Itisoneoftheimportantpartsinthegeneralmachinery,particularlytheengineeringmachinerytransmission.Theoptimizationofthegearshaft’smachiningmaterials,thermaltreatmentmethodandmachiningprocesswillhavegreatsignificanceonthemachiningqualityofthegearshaftandtheservicelife.Thefirstdesignofthegearshaftpartsandpartsofthematerial,thenfixtheprocessinggearshaftofthematerialsusedandthetypeofproduction.Andthendeterminetheblanktype,drawingcastingpartsdiagram.Theprocessingofthenextdesignofparts,includingthecomponentssurfaceprocessingmethodandheattreatmentmethod.Finally,technologicalprocessdesign,selectionofthemachinetool,cuttingtool,fixtureetc…Comprehensivemechanicalperformancerequirementshighergearshaftparts,asgeneralforgingblank.Reasonablearrangementsfortheprocess,dividingtheprocessingstageisveryimportanttoensurethemachiningqualityofparts.Keywordsgearshaft;processanalysis;processplanningdesign目录-III-目录摘要.............................................................................................................................IABSTRACT......................................................................................................................II第1章绪论.............................................................................................................-1-第2章零件的分析......................................................................................................22.1零件的作用.............................................................................................................................22.1.1零件的作用......................................................................................................................22.1.2零件的结构特点及技术要求..........................................................................................22.2零件材料分析.........................................................................................................................32.3确定生产类型.........................................................................................................................32.4毛坯的确定.............................................................................................................................42.5绘制铸件零件图.....................................................................................................................42.6本章小节................................................................................................................................5第3章加工工艺过程分析..........................................................................................53.1加工工艺过程的组成.............................................................................................................63.2定位基准的选择原则............................................................................................................63.2.1基准的概念......................................................................................................................63.2.2定位基准的选择.............................................................................................................73.2.3定位基准的确定.............................................................................................................83.3零件表面加工方法的选择..................................................................................................103.4加工工序安排......................................................................................................................103.5热处理工序的安排..............................................................................................................113.6工序的划分..........................................................................................................................113.7加工余量及工序尺寸的确定..............................................................................................123.7.1加工余量的概念...........................................................................................................123.7.2加工余量的确定方法...................................................................................................123.8本章小结..............................................................................................................................13第4章选择加工设备及工艺设备............................................................................144.1各机床的作用.......................................................................................................................144.1.1车床的作用........................................................................................
