沖擊式破碎機設(shè)計說明書.doc

1摘要沖擊式破碎機是廣泛運用于特硬、中硬及磨蝕性物料的粗碎與細碎作業(yè)的高效破碎機械設(shè)備。在設(shè)計初，先查閱資料，了解了沖擊式破碎機在國內(nèi)外的現(xiàn)狀。然后按照破碎機的一般設(shè)計步驟進行了以下設(shè)計：破碎機總體方案確定及主軸等主要零件結(jié)構(gòu)參數(shù)的計算和選擇；破碎機工作參數(shù)的計算；破碎機結(jié)構(gòu)設(shè)計；破碎機的受力分析和主要零部件的強度校核。最后完成破碎機裝配圖，主要部件及零件圖，設(shè)計說明書一份。關(guān)鍵詞：沖擊式破碎機；傳送帶；葉輪；軸2AbstractTheimpactcrusheriswidelyusedinspecialhard,hardandabrasivematerials,roughbrokenandmechanicalcrushingoperationsefficiencyimpactcrusher.Throughthisgraduationproject,tostudyontheconsolidationofbookknowledge.Earlyinthedesign,toinspecttheinformationabouttheimpactcrusherathomeandabroad.Thenfollowtheimpactcrusherofthegeneraldesignstepsofthefollowingdesign:theoverallplanofimpactcrusherandcalculationandchoiceofthemainshaftandtheothermajorpartstodeterminestructuralparameters；thecalculationofimpactcrusherworkingparameters；impactcrusherstructuraldesign；checkofthestressanalysisandstrengthofmajorcomponents.Finallycompleteaassemblydrawingsofimpactcrusher,partsdiagram,thedesignofapaper.Keywords:impactcrusher；conveyorbelt；impeller；shaft3目錄摘要ABSTRACT第1章緒論11.1選題背景11.2國內(nèi)外發(fā)展現(xiàn)狀21.3歷史發(fā)展過程與未來發(fā)展方向3第2章破碎機的總體方案設(shè)計52.1沖擊式破碎機的總體方案設(shè)計52.2沖擊式破碎機的結(jié)構(gòu)72.3沖擊式破碎機的工作原理92.4沖擊式破碎機的特點102.5沖擊式破碎機的主要部件112.5.1葉輪122.5.2反擊板13第3章破碎機的結(jié)構(gòu)設(shè)計與計算153.1破碎機主要工作參數(shù)的確定153.1.1沖擊速度的確定153.1.2沖擊時間的確定153.1.3電機功率的確定163.1.4葉輪結(jié)構(gòu)參數(shù)的確定163.2破碎機主要零件設(shè)計及其參數(shù)的選定183.2.1多楔帶設(shè)計183.2.2主軸設(shè)計203.2.3軸承設(shè)計223.2.4鍵的選擇與校核243.2.5反擊板設(shè)計243.2.6螺栓強度校核2543.3機架設(shè)計263.3.1機架的類型、材料及制造方法選擇263.3.2機架結(jié)構(gòu)的設(shè)計27第4章破碎機的安裝和維護304.1沖擊式破碎機的安裝、調(diào)整與試運轉(zhuǎn)說明304.1.1設(shè)備的安裝304.1.2設(shè)備的調(diào)整304.1.3機器的試轉(zhuǎn)314.2沖擊式破碎機的使用與維護要求31結(jié)論34致謝35參考文獻365CONTENTSAbstractChapter1Introduction11.1Researchbackground11.2DevelopmentStatus21.3Thehistoricaldevelopmentandfuturedevelopmentdirection3Chapter2Crushingmachineoverallplandesign52.1Impactcrusherdesignargument52.2Impactcrushersstructure72.3Impactcrusherworkingprinciple92.4Impactcrusherfeatures102.5MaincomponentsoftheimpactcrusherProfile112.5.1Impeller122.5.2Thecounterattackplate13Chapter3Crusherstructuredesignandcalculation153.1Impactcrushermainworkingparametersoftheselectedcounterboard153.1.1Impactvelocity153.1.2Todeterminetheimpactoftime153.1.3MotorPower163.1.4Impellerstructuralparameters163.2Partsanditsparametersele
