Umgodi we-crank.
Ingxenye ebaluleke kakhulu yenjini. Ithatha amandla enduku yokuxhuma bese iwaguqula abe yi-torque output nge-crankshaft bese iqhuba ezinye izesekeli enjinini ukuthi zisebenze. I-crankshaft ithintwa amandla e-centrifugal e-rotation mass, i-periodic gas inertia force kanye ne-reciprocating inertia force, okwenza i-crankshaft ithwale isenzo sokugoba kanye nomthwalo wokugoba. Ngakho-ke, i-crankshaft iyadingeka ukuthi ibe namandla nokuqina okwanele, futhi ubuso be-journal kufanele bumelane nokuguguleka, bufane futhi bulingane.
Ukuze kuncishiswe isisindo se-crankshaft kanye namandla e-centrifugal akhiqizwa ngesikhathi sokunyakaza, i-crankshaft journal ivame ukuba yimbobo. Indawo ngayinye ye-journal inikezwa imbobo yamafutha yokungenisa noma ukukhipha uwoyela ukuze kugcotshwe indawo ye-journal. Ukuze kuncishiswe ukugxilisa ingqondo, ukuxhumana kwentamo ye-spindle, iphini le-crank kanye nengalo ye-crank kuxhunywe nge-arc yesikhashana.
Indima ye-crankshaft counterweight (eyaziwa nangokuthi i-counterweight) ukulinganisela amandla ajikelezayo e-centrifugal kanye nomzuzu wayo, futhi ngezinye izikhathi amandla angenawo amandla kanye nomzuzu wayo. Uma la mandla kanye nezikhathi ngokwazo zilinganiselwe, isisindo sebhalansi singasetshenziswa futhi ukunciphisa umthwalo kubhere eliyinhloko. Inombolo, usayizi kanye nokubekwa kwesisindo sebhalansi kufanele kucatshangelwe ngokuya ngenani lamasilinda enjini, ukuhlelwa kwamasilinda kanye nesimo se-crankshaft. Isisindo sebhalansi ngokuvamile siphonswa noma sakhiwe sibe yinye ne-crankshaft, futhi isisindo sebhalansi yenjini yedizili enamandla aphezulu sakhiwa ngokwehlukana ne-crankshaft bese sihlanganiswa ndawonye.
Ukuncibilikisa
Ukuthola insimbi eshisayo ehlanzekile enezinga lokushisa eliphezulu kanye nesibabule esincane kuyisihluthulelo sokukhiqiza insimbi ethambile esezingeni eliphezulu. Imishini yokukhiqiza yasekhaya isekelwe kakhulu ku-cupola, futhi insimbi eshisayo akuyona ukwelashwa kwangaphambi kokukhipha i-sulfurization; Lokhu kulandelwa insimbi yengulube emsulwa kancane kanye nekhwalithi ye-coke ephansi. Insimbi encibilikisiwe iyancibilikiswa ku-cupola, ikhishwe i-sulfur ngaphandle kwesithando, bese ishiswa futhi ilungiswe ku-induction furnace. E-China, ukutholakala kokwakheka kwensimbi encibilikisiwe kuye kwenziwa ngokuvamile nge-vacuum direct reading spectrometer.
ukubumba
Inqubo yokubumba umoya ngomthelela iphakeme kakhulu kunenqubo yokubumba isihlabathi sobumba, futhi ingathola ukubumba kwe-crankshaft okunembe kakhulu. Isikhunta sesihlabathi esikhiqizwa yile nqubo sinezici zokungaguquguquki kwe-rebound, okubaluleke kakhulu kwi-crankshaft ephonsa okuningi. Abanye abakhiqizi be-crankshaft basekhaya abavela eJalimane, e-Italy, eSpain nakwamanye amazwe ukwethula inqubo yokubumba umoya ngomthelela, kodwa ukwethulwa komugqa wokukhiqiza wonke kuncane kakhulu kwabakhiqizi.
Ukuphonswa kwe-Electroslag
Ubuchwepheshe bokuncibilikisa i-electroslag busetshenziswa ekukhiqizweni kwe-crankshaft, ukuze ukusebenza kwe-crankshaft ehlanganisiwe kufane nokwe-crankshaft eyenziwe. Futhi inezici zomjikelezo wokuthuthuka okusheshayo, izinga eliphezulu lokusetshenziswa kwensimbi, imishini elula, ukusebenza komkhiqizo okuphezulu njalo njalo.
Ubuchwepheshe bokwakha
Umugqa ozenzakalelayo one-hot die forging press kanye ne-electric hydraulic hammer njengenjini eyinhloko kuyindlela yokuthuthukiswa kokukhiqizwa kwe-crankshaft. Le migqa yokukhiqiza ngokuvamile izosebenzisa ubuchwepheshe obuthuthukisiwe njengokusika ngokunemba, ukwakheka kwe-roll forging (cross wedge rolling), ukushisa kwe-medium frequency induction, ukuqeda i-hydraulic press finishing, njll. Ngesikhathi esifanayo, ifakwe imishini esekelayo efana nama-manipulators, amabhande okuhambisa kanye namadivayisi okushintsha isikhunta abuyiselwe ku-turntable ukuze akhe uhlelo lokukhiqiza oluguquguqukayo (i-FMS). I-FMS ingashintsha ngokuzenzakalelayo i-workpiece bese ifa bese ilungisa ngokuzenzakalelayo amapharamitha, futhi ilinganise njalo ngesikhathi senqubo yokusebenza. Bonisa futhi urekhode idatha efana nobukhulu be-forging kanye nengcindezi ephezulu bese uqhathanisa namanani aqinile ukuze ukhethe ukuguqulwa okungcono kakhulu kwemikhiqizo yekhwalithi. Lonke uhlelo luqashwa yigumbi lokulawula eliphakathi, okuvumela ukusebenza okungalawulwa. I-crankshaft eyakhiwe ngale ndlela ye-forging ine-fiber ephelele yomugqa wokugeleza kwensimbi yangaphakathi, engandisa amandla okukhathala ngaphezu kwama-20%.
Uma ufuna ukwazi okwengeziwe, qhubeka ufunda ezinye izihloko ezikulesi siza!
Sicela usishayele ucingo uma udinga imikhiqizo enjalo.
I-Zhuo Meng Shanghai Auto Co., Ltd. izibophezele ekuthengiseni izingxenye zezimoto ze-MG&MAUXS futhi wamukelekile ukuzithenga.
