车床主轴箱设计毕业设计

编号潍坊学院毕业设计技术报告课题名称：车床主轴箱设计学生姓名：学号：专业：机械设计制造及其自动化班级：机制本二指导教师：2015年06月潍坊学院本科毕业设计I摘要CA6140作为主要的车削加工车床，被广泛的应用于机械加工行业。随着经济的发展以及对国外先机技术的学习和引进，我国的车床行业在世界上起到了举足轻重的作用。主轴箱是车床中重要的组成部分，整个车床的动力传动就是由它控制的。主轴箱直接影响着车床的工作效率，由此可知主轴箱的重要程度。本设计是主要针对CA6140车床主轴箱的设计，车床主轴箱是一个比较复杂的传动部件。根据当前实际情况，考虑到经济性和效率性等相关因素，对车床主轴箱进行合理构思构想,最终完成对车床主轴箱的设计。设计的内容主要有参数的确定，拟定传动与变速的结构方案和传动系统图，传动设计，传动件的估算和校核，各部件结构设计和主轴组件的校核几个部分部分来进行设计的。以齿轮、带轮、皮带轮、轴承、等的参数设计为重点，并利用制图软件进行了零件的设计和处理。关键词：CA6140车床主轴箱传动零件潍坊学院本科毕业设计IIAbstractCA6140asthemainturninglathe,CA6140iswidelyusedinmechanicalprocessingindustry.Withthedevelopmentofeconomyaswellastothelearningandintroducingforeignadvantagetechnology,latheindustryinChinahasplayedapivotalroleintheworld.Spindleboxistheimportantpartofthelatheanditcontrolledthepowertransmissionofthewholelathe.Spindleboxdirectlyaffectstheworkefficiencyofmachinetool,thustheimportanceofthespindleboxisgoeswithoutsaying.ThisdesignismainlyforCA6140lathespindleboxdesign,andlathespindleboxisamorecomplicateddrivingpart.Accordingtothecurrentactualsituation,consideringthefactorsrelatedtoeconomyandefficiency,toreasonabledesignideaoflathespindlebox,finallycompletedthedesignoflathespindlebox.Themajordesigncontentincludingthedeterminationoftheparameters,formulatetransmissionandvariablestructureschemeandsystemdiagram,transmissiondesign,theestimateandcheckoftransmissionparts,thedesignofthecomponentsstructureandthecheckthespindlecomponent.Focusontheparameterdesignofgear,beltpulley,bearingandsoon,andusethegraphicssoftwarefordesigningandprocessingoftheparts.Keywords:CA6140lathe;spindlebox;transmission;parts潍坊学院本科毕业设计III目录摘要...........................................................................................................................................IAbstract......................................................................................................................................II第一章绪论............................................................................................................................11.1车床的发展及主轴箱的作用.......................................................................................11.1.1车床的发展历史.................................................................................................11.1.2主轴箱的作用.....................................................................................................21.2主传动系统的设计要求...............................................................................................3第二章传动设计......................................................................................................................42.1主传动方案设计...........................................................................................................42.2选择传动结构式和结构网...........................................................................................42.2.1确定传动组及传动副的数目.............................................................................42.2.2传动式的拟定.....................................................................................................42.2.3结构式的拟定.....................................................................................................42.3转速图的拟定...............................................................................................................52.4传动轴的设计...............................................................................................................52.5主轴箱的箱体...............................................................................................................6第三章动力设计......................................................................................................................73.1确定各轴转速及检查...................................................................................................73.2带传动设计...................................................................................................................83.3齿轮模数的确定以及模数的校核.............................................................................103.4齿轮强度校核.............................................................................................................123.5主轴挠度的计算和校核.............................................................................................15第四章离合器的选择及其计算............................................................................................17第五章传动件验算................................................................................................................195.1轴的强度校核.............................................................................................................195.2验算花键键挤压应力.................................................................................................195.3滚动轴承校核.............................................................................................................205.4齿轮的强度计算.........................................................................................................215.5计算跨距.....................................................................................................................22第六章结论..............
