文档介绍：摘要辊式破碎机广泛应用于水泥业和采矿业,由于其效率高,能耗小,处理量大等优点受到一致好评,辊式破碎机技术还在不断完善,各方面的性能还在不断优化,应用前景还是非常广阔的。我完成的设计内容主要是辊式破碎机主机的设计,包括了机架,辊子,轴承的设计和强度校核,还有一些主要参数的确定。主机设计的主要目的是将液压系统和传动系统组合成一个整体,使辊式破碎机能正常工作。辊子的设计和轴承的选择在主机设计中是非常重要的,整个破碎机主要的工作装置就是两个辊子,通过两个辊子的反向转动将从进料口进来的物料压碎。轴承则是主要的承载装置,承受着巨大的静载荷和冲击载荷,这两个零件关系着整部机器的运转。在确定出主要参数后,我就从辊子的设计入手,然后是轴承的选择和机架的设计和校核。经过各种校核计算证明了我的设计是可行的,辊子,轴承,机架都能满足已给定的要求。设计中还有一些对给料装置和润滑,冷却系统的简要说明。我的设计只是自己的一些想法,没有经过实践的验证,肯定会有很多不成熟的地方,这就有待我在今后的工作中积累经验,使自己的设计思想越来越成熟。关键词:辊子,轴承,机架,主机设计AbstractTherollscrusherisextensivelyappliedinthecementindustryandtheopencastindustry,becauseitsefficiencyishigh,canconsumesmall,theprocessinghasgreatcapacitytowaittheadvantagetobesubjectedtotheconsistentgoodopinion,andtherollscrushertechniquereturnatcontinuouslyperfect,thefunctionofeveryone'snoodlesreturnatcontinuouslyexcellentturn,applytheforegroundstillveryvastof。pletemainlyisthedesignoftherollscrusherhost,includingthedesignandthestrengthcheckingoftheframe,therollsandthebearings,havingsometheassuranceofthemainparameter。Thehostdesignofthemainpurposeistopressliquidsystemandspreadtomovethesystemtoconstituteawhole,makethenormalworkofthebrokenupfunctionoftherollscrusher。Thedesignoftherollsandthechoiceofthebearingsarecountformuchinhostdesign,themainworkdeviceofwholecrusheristworolls,einfromfeedport。Bearingsthenthemainloadingequip,bearingtohugelycalmdowntocarrythelotusandimpacttocarrythelotus,thesetwosparepartsesrelatetotheoperationofwholemachine。Afterthecertainmainparameter,Icommencefromthedesignoftherolls,thenisthechoiceofthebearingsandthedesignandthecheckingofthemachine。Mydesignisprovedtoisviablebyvariouscheckingandcounting,therolls,bearingsandframecansatisfytoalreadybegiventherequesting。Designingalsoincludeabriefdescriptiontofeeddevice,lubricatingsystemandcoolingsystem。Mydesignisjustalittlebitownviewpoint,anddon’tbevalativedbythepractice,theaffirmationwillhavealotofnotmatureplaces。Iwillpileupexperiencesinfutureworking,andmakeowndesignthoughtmoreandmoremature。Keyword:roll,bearing,frame,hostdesign目录第一
