I-crank shaft.
Ingxenye ebaluleke kakhulu yenjini. Ithatha amandla entongeni yokuxhuma bese iwaguqulela ekuphumeni kwetorque nge-crankshaft bese ishayela ezinye izesekeli enjinini ukuthi zisebenze. I-crankshaft ithintwa amandla ayi-centrifugal obuningi obujikelezayo, amandla e-periodic inertia yegesi namandla aphindaphindayo e-inertia, okwenza i-crankshaft ithwale isenzo sokugoba kanye nomthwalo we-torsional. Ngakho-ke, i-crankshaft iyadingeka ukuze ibe namandla anele nokuqina, futhi indawo yejenali kufanele ingagugi, ifane futhi ilinganisele.
Ukuze kuncishiswe isisindo se-crankshaft namandla aphakathi nendawo akhiqizwa ngesikhathi sokunyakaza, ijenali ye-crankshaft ivamise ukungabi nalutho. Indawo ngayinye yejenali ihlinzekwa ngembobo kawoyela yokwethulwa kukawoyela noma ukukhipha ukuze kugcotshwe indawo yejenali. Ukuze kuncishiswe ukugxiliswa kwengcindezi, ukuxhumana kwentamo yokuphotha, iphinikhodi ne-crank arm kuxhunywe i-arc yesikhashana.
Iqhaza le-crankshaft counterweight (eyaziwa nangokuthi i-counterweight) ukulinganisa amandla ajikelezayo amaphakathi kanye nomzuzu wawo, futhi ngezinye izikhathi amandla angenayo aphindaphindayo kanye nomzuzu wawo. Lapho lawa mandla kanye nezikhathi ngokwazo zilinganiselwe, isisindo sokulinganisa singasetshenziselwa ukunciphisa umthwalo ekuthwaleni okuyinhloko. Inombolo, ubukhulu kanye nokubekwa kwesisindo sebhalansi kufanele kubhekwe ngokwenani lamasilinda enjini, ukuhlelwa kwamasilinda kanye nokuma kwe-crankshaft. Isisindo sebhalansi sivamise ukuphonswa noma sihlanganiswe sibe yinye nge-crankshaft, futhi isisindo sebhalansi yenjini ye-diesel enamandla amakhulu sikhiqizwa ngokuhlukana ne-crankshaft bese sihlanganiswa ndawonye.
Ukuncibilika
Ukuthola izinga lokushisa eliphezulu nesibabule esiphansi sensimbi ehlanzekile ehlanzekile kuyisihluthulelo sokukhiqiza insimbi yekhwalithi ephezulu ene-ductile. Imishini yokukhiqiza yasekhaya isekelwe ikakhulukazi ku-cupola, futhi insimbi eshisayo ayiyona ukwelashwa kwangaphambili kwe-desulfurization; Lokhu kulandelwa ukuhlanzeka okuncane kwezingulube zensimbi kanye nekhwalithi ye-coke empofu. Insimbi encibilikisiwe incibilika ku-cupola, ikhishwe ngaphandle kwesithando somlilo, bese iyashisisa futhi ilungiswe esithandweni sokungenisa. E-China, ukutholwa kokwakheka kwensimbi encibilikisiwe ngokuvamile kwenziwa nge-vacuum direct reading spectrometer.
ukubumba
Inqubo yokubumba umthelela womoya ngokusobala iphakeme kunenqubo yokubumba isihlabathi sobumba, futhi ingathola ukunemba okuphezulu kwe-crankshaft castings. Isikhunta sesihlabathi esikhiqizwa yile nqubo sinezici zokungaguquki kwe-rebound, okubaluleke kakhulu ku-crankshaft yokuphonsa okuningi. Abanye abakhiqizi be-crankshaft basekhaya abavela eJalimane, e-Italy, eSpain nakwamanye amazwe ukuze bethule inqubo yokubumba umthelela womoya, kodwa ukwethulwa kwawo wonke umugqa wokukhiqiza kuyinani elincane kakhulu labakhiqizi.
Ukukhishwa kwe-Electroslag
Ubuchwepheshe be-Electroslag remelting busetshenziswa ekukhiqizweni kwe-crankshaft, ukuze ukusebenza kwe-cast crankshaft kuqhathaniswe nalokho kwe-crankshaft eyenziwe ngomgunyathi. Futhi inezici zomjikelezo wokuthuthukiswa okusheshayo, izinga eliphezulu lokusebenzisa insimbi, imishini elula, ukusebenza okuphezulu komkhiqizo nokunye.
Forging technology
Ulayini ozenzakalelayo onomshini wokushiswa we-hot die forging kanye nesando esisebenza ngogesi esisebenza ngogesi njengoba injini eyinhloko iyindlela yokuthuthukiswa kokukhiqizwa kwe-crankshaft. Le migqa yokukhiqiza ngokuvamile izosebenzisa ubuchwepheshe obuthuthukisiwe njengokusika okunembayo, ukubumba i-roll (ukugoqeka kwe-cross wedge) ukwakha, ukushisa okuphakathi kwe-medium frequency, ukuqedela ukucindezela kwe-hydraulic, njll. amabhande kanye namadivayisi okushintsha isikhunta abuyiselwe ku-turntable ukuze akhe uhlelo lokukhiqiza oluguquguqukayo (FMS). I-FMS ingashintsha ngokuzenzakalelayo i-workpiece futhi ife futhi ilungise ngokuzenzakalelayo imingcele, futhi ihlale ikala phakathi nenqubo yokusebenza. Khombisa futhi urekhode idatha efana nokuqina kokufoja nokucindezela okukhulu futhi uqhathanise namanani angashintshi ukuze ukhethe ukuwohloka okungcono kakhulu kwemikhiqizo yekhwalithi. Lonke uhlelo luqashwe yigumbi lokulawula eliphakathi, elivumela ukusebenza okungenamuntu. I-crankshaft eyakhiwe yile ndlela yokubumba inomucu ogcwele womugqa wokugeleza kwensimbi wangaphakathi, ongakhuphula amandla okukhathala ngaphezu kwama-20%.
Uma ufuna ukwazi okwengeziwe, qhubeka ufunda ezinye izihloko kule sayithi!
Sicela usishayele uma udinga imikhiqizo enjalo.
UZhuo Meng Shanghai Auto Co., Ltd. uzibophezele ekuthengiseni izingxenye zezimoto ze-MG&MAUXS wamukelekile ukuzithenga.
