采煤机截割部的整体设计毕业论文.doc

辽宁工程技术大学毕业设计(论文)1摘要我所设计的题目是采煤机的截割部设计,即截割部的设计。当前我国采煤技术已经有了一定的发展,而且逐渐趋于自动化。通过老师任务书的下达,我初步了解了我所要设计的采煤机的截割部的用途用于进行地下采煤工作。通过对此题目的分析以及对一些相关书籍和文献的查阅,截割部的设计重点应在于摇臂传动部分的设计。本设计的主要内容包括对课题的来源、选题的目的、以及截割部在国内外发展的形势,及所存在的问题进行了相关的论述。采煤机截割部分一般结构,然后根据自身的需求选取适当的结构组件。掌握一些基本概念、特点、应用以及基本工序,进而分析采煤技术的现状和发展方向,这样就能使大家对采煤技术有了总体的认识。掌握的重点对摇臂传动部进行设计。先分析力的传动过程然后对截割部进行工艺分析,为设计奠定基础最后对截割部传动进行整体设计,画好装配图。最后对以设计出的数据进行整理和验算。关键词采煤机截割部传动部分摇臂电动机唐磊采煤机截割部设计2ABSTRACTIdesignisthesubjectoftheshearercuttingdesign,thecuttingofthedesign.Chinascurrentminingtechnologyhasmadecertaindevelopmentandthegrowingtrendofautomation.Teachersthroughthemandatewasissued,Myinitialunderstandingofmydesignoftheshearercuttingunitusesfortheundergroundminingwork.Throughtheanalysisofthistopicandanumberofrelatedbooksandliteraturesearch,CuttingtheMinistryofdesignshouldfocusonthetransmissionarmofthedesign.Thedesignofthemaincontentsincludethesourceofthesubject,thepurposeoftopics,andthecuttingofthedevelopmentofthesituationathomeandabroad,andtheproblemsrelatedtotheexposition.Shearercuttingsomeofthegeneralstructure,accordingtotheneedsoftheirownselectionofappropriatestructuralcomponents.Mastersomebasicconcepts,features,applicationsandbasicprocesses,therebyminingtechnologyanalysisofthestatusanddirectionofdevelopment,Thiswillenableeveryonetohaveminingtechnologyoverallawareness.GraspthekeyrightarmoftheDepartmentoftransmissiondesign.AnalyzetheedgeofthedriveThencuttingtheDepartmentofTechnicalAnalysisandlaythefoundationforthedesignFinally,theMinistryofcuttingdriveoveralldesign,drawnassembly.Finally,thedesignofdatacollationandchecking.KeywordsShearerCuttingDepartmentTransmissionRockerMotor目录前言..................................................................................................................11绪论.............................................................................................................71.1课题的设计目的及意义......................................................................71.2与课题相关国内外研究现状分析.......................................................71.2.1采煤机在国内的发展情况.........................................................71.2.2国外采煤机的发展.....................................................................91.2.3对采煤机在国内发展的建议.....................................................111.3设计内容和预期结果.........................................................................121.3.1设计内容..................................................................................12辽宁工程技术大学毕业设计(论文)31.3.2预期结果..................................................................................122采煤机的概述.............................................................................................133.截割部的整体设计....................................................................................143.1截割部的组成................................................................................143.1.1截割部主要作用.......................................................................143.2采煤机的主要工作参数.....................................................................143.2.1采高......................................................................................143.2.2截深..........................................................................................153.2.3截割速度..................................................................................153.2.4牵引速度.....................................................................................153.2.5牵引力......................................................................................163.2.6生产能力..................................................................................163.2.7装机功率..................................................................................163.3齿型选择............................................................................................183.3.1截齿..........................................................................................183.3.2截齿的几何参数.......................................................................183.3.3截齿的分类.................................................................................193.3.4截齿伸出长度......................................................................223.3.5截齿的失效形式与寿命..............................................................223.3.6截齿的材料.................................................................................223.4滚筒设计..............................................................................................223.4.1滚筒的结构参数......................................................................23唐磊采煤机截割部设计43.4.2滚筒宽度..................................................................................243.5螺旋滚筒的运动参数.........................................................................283.5.1滚筒的旋转方向.......................................................................283.5.2滚筒的转速...............................................................................303.6截齿配置............................................................................................313.7电动机的选择计算........................................
