自动核桃脱壳机设计和实现 机械制造自动化专业VIP专享VIP免费

1摘要本次设计为自动核桃脱壳机设计，原来的机器进行剥壳的过程比较繁琐，这款核桃脱壳机主要的工作原理便是利用蜗杆蜗轮传动的慢进和曲柄滑块机构的快砸的特点，这样既可以提高产量，又大大节省了人力物力，从而使得下降。本文主要介绍了自动核桃脱壳机的工作原理、直齿齿轮曲柄滑块机构的运动特点、各部分的分工及其作用、材料的选择及其计算。设计中涉及到带传动、链传动、直齿圆柱齿轮传动以及曲柄滑快机构的运动，经过计算他可以准确的去除果皮，去除的果皮落入废果皮箱中，以此来实现提高剥壳效率，使核桃脱壳更加简易便捷。关键词：核桃脱壳机；标准直齿圆柱齿轮；曲柄滑块机构；链传动；ABSTRATThisdesignisdesignedforautomaticwalnutsheller.Theprocessoftheoriginalmachineistedious.Themainworkingprincipleofthiswalnutshelleristousetheslowspeedofwormandwormgeardriveandthequicksmashingofthecrankslidermechanism.Thiscannotonlyimprovetheoutput,butalsosavethemanpowerandmaterialresources,whichmakesitdecline.Thispapermainlyintroducestheworkingprincipleoftheautomaticwalnutsheller,themovementcharacteristicsofthecrankslidermechanismofthespurgear,thedivisionoflaboranditsfunction,theselectionandcalculationofthematerial.Thedesigninvolvesthemovementofbeltdrive,chaindrive,spurgeardriveandcrankfastmechanism.Aftercalculation,hecanaccuratelyremovethepeelandremovethepeelintothewastefruitsuitcase,inordertoimprovetheefficiencyofshellpeelingandmakethewalnutshellingeasierandeasier.Keywords:walnutsheller;Standardstraighttoothcylindricalgear;Crankslidermechanism;Chaindrive;2目录1绪论...........................................................11.1设计研究的意图和意义........................................11.2国内外研究现状..............................................11.3本设计的总体方案............................................12动力装置的选择.................................................32.1选择电动机的类型............................................32.2选择电动机功率..............................................33自动脱壳机轴的带及带轮的设计...................................43.1传动带的设计................................................43.1.1确定计算功率............................................43.1.2选择V带的型号..........................................43.1.3确定带轮的基准直径......................................43.1.4验算带速................................................53.1.5确定传动中心距a和带长L.................................53.1.6确定V带的根数..........................................63.1.7确定带的初拉力..........................................63.1.8求V带传动作用在轴上的压力..............................63.2V带带轮的设计..............................................73.2.1带轮的材料选择..........................................73.2.2结构设计................................................73.2.3从动带轮的设计..........................................834自动脱壳机轴的设计.............................................94.1轴上的功率P、转速n、转矩T..................................94.2轴的材料选择................................................94.3初步确定轴的最小直径.......................................104.4轴的结构设计...............................................104.4.1假设轴上零件的装配方案.................................114.4.2确定轴的各段直径和长度.................................114.4.3轴上零件的轴向定位.....................................154.4.4确定轴上圆角和倒角尺寸.................................154.5轴的疲...
