I-crank shaft.
Eyona nxalenye ibalulekileyo injini. Ithatha amandla ukusuka kwintonga yokudibanisa kwaye iyiguqule ibe yitorque ephuma kwi-crankshaft kwaye iqhube ezinye izincedisi kwi-injini ukuba zisebenze. I-crankshaft ichatshazelwa ngamandla we-centrifugal yobunzima obujikelezayo, amandla e-inertia yegesi ephindaphindiweyo kunye ne-inertia yamandla aphindaphindayo, okwenza ukuba i-crankshaft ithwale isenzo sokugoba kunye nomthwalo ojikelezayo. Ke ngoko, i-crankshaft iyadingeka ukuba ibe namandla okwaneleyo kunye nokuqina, kwaye umphezulu wejenali kufuneka unganxibi, ufane kwaye ulungelelane.
Ukuze kuncitshiswe ubunzima becrankshaft kunye necentrifugal force eveliswa ngexesha lentshukumo, ijenali yecrankshaft ihlala ingenanto. Umphezulu wejenali nganye ibonelelwa ngomngxuma oyile wokwazisa ioyile okanye ukutsalwa ukuthambisa umphezulu wejenali. Ukuze kuncitshiswe uxinzelelo loxinzelelo, ukudityaniswa kwentamo ye-spindle, i-crank pin kunye ne-crank arm zixhunywe yi-arc yenguqu.
Indima ye-crankshaft counterweight (ekwaziwa ngokuba yi-counterweight) kukulinganisa amandla ajikelezayo e-centrifugal kunye nomzuzu wayo, kwaye ngamanye amaxesha amandla aphindaphindayo angenayo kunye nomzuzu wawo. Xa le mikhosi kunye namaxesha ngokwawo alungelelaniswa, ubunzima bokulinganisela bunokusetyenziswa kwakhona ukunciphisa umthwalo kwi-bearing engundoqo. Inani, ubungakanani kunye nokubekwa kobunzima bokulinganisa kufuneka kuqwalaselwe ngokwenani leesilinda ze-injini, ukucwangciswa kweesilinda kunye nokumila kwe-crankshaft. Ubunzima bebhalansi ngokuqhelekileyo buphoswa okanye bubunjwe bube bubenye kunye necrankshaft, kwaye ubunzima bomlinganiselo we-injini yedizili enamandla amakhulu wenziwe ngokwahlukileyo kwicrankshaft emva koko ibotshelelwe kunye.
Ukunyibilika
Ukufumana ubushushu obuphezulu kunye nesulfure ephantsi ecocekileyo yentsimbi eshushu ngundoqo ekuveliseni umgangatho ophezulu we-ductile iron. Izixhobo zokuvelisa zasekhaya zisekelwe ikakhulu kwi-cupola, kwaye isinyithi esishushu asiyiyo unyango lwangaphambili lwe-desulfurization; Oku kulandelwa yintsimbi yehagu engacocekanga kakhulu kunye nomgangatho ophantsi wecoke. Intsimbi etyhidiweyo inyibilika kwi-cupola, i-desulfurized ngaphandle kwesithando somlilo, kwaye emva koko ishushu kwaye ilungelelaniswe kwisithando somlilo. E-China, ukufunyaniswa kokwakheka kwesinyithi esinyibilikisiweyo kuqhutywe ngokubanzi nge-vacuum yokufunda ngokuthe ngqo i-spectrometer.
ukubumba
Inkqubo yokubumba impembelelo yomoya ngokucacileyo ingaphezulu kwenkqubo yokubumba isanti yodongwe, kwaye inokufumana ii-crankshaft castings ezichanekileyo. Isikhunta sesanti esiveliswe yile nkqubo sineempawu zokungaphindi zibuyele, nto leyo ibaluleke kakhulu kwi-crankshaft ye-multi-throw. Abanye abavelisi be-crankshaft basekhaya abavela eJamani, eItali, eSpain nakwamanye amazwe ukwazisa inkqubo yokubumba impembelelo yomoya, kodwa ukuqaliswa komgca wemveliso wonke linani elincinane kakhulu labavelisi.
Ukuphosa i-Electroslag
Itekhnoloji yokunyibilikisa i-Electroslag isetyenziswa ekuveliseni i-crankshaft, ukuze ukusebenza kwe-crankshaft eyicast ithelekiseke naleyo ye-crankshaft eyenziweyo. Kwaye ineempawu zomjikelo wokuphuhlisa ngokukhawuleza, izinga eliphezulu lokusetyenziswa kwesinyithi, izixhobo ezilula, ukusebenza kwemveliso ephezulu kunye nokunye.
Ukudala iteknoloji
Umgca ozenzekelayo kunye nesando sokwenza umbane otshisayo kunye nehamile yombane ye-hydraulic njengoko i-injini engundoqo isalathiso sophuhliso lwemveliso ye-crankshaft. Le migca yemveliso iya kwamkela ngokubanzi itekhnoloji ephucukileyo efana nokusika ngokuchanekileyo, ukubumba umqulu (ukuqengqeleka komnqamlezo) ukwenza, ukufudumeza okuphakathi kwamaxesha aphakathi, ukugqiba ukucofa koxinzelelo lwehydraulic, njl. Kwangaxeshanye, baxhotyiswe ngoomatshini abancedisayo abafana neemanipulators, conveyor. amabhanti kunye nezixhobo zokutshintsha umngundo zibuyiselwe kwi-turntable ukwenza inkqubo yokuvelisa i-flexible (FMS). I-FMS inokutshintsha ngokuzenzekelayo i-workpiece kwaye ife kwaye ilungelelanise ngokuzenzekelayo iiparamitha, kwaye ihlale ilinganisa ngexesha lenkqubo yokusebenza. Bonisa kwaye urekhode idatha efana nokubunjwa kobungqingqwa kunye noxinzelelo oluphezulu kwaye uthelekise namaxabiso amiselweyo ukukhetha eyona deformation kwimveliso esemgangathweni. Inkqubo yonke ibekwe esweni ligumbi lokulawula eliphakathi, elivumela ukusebenza okungenamntu. I-crankshaft eyenziwe yile ndlela yokubumba ine-fiber epheleleyo yomgca wentsimbi yangaphakathi, enokunyusa amandla okukhathala ngaphezu kwe-20%.
