Crank ncej.
Qhov tseem ceeb tshaj plaws ntawm lub cav. Nws siv lub zog los ntawm tus pas txuas txuas thiab hloov mus rau hauv cov zis tawm los ntawm lub crankshaft thiab tsav lwm yam khoom siv ntawm lub cav ua haujlwm. Lub crankshaft yog cuam tshuam los ntawm centrifugal quab yuam ntawm rotating loj, lub sij hawm roj inertia quab yuam thiab reciprocating inertia quab yuam, uas ua rau lub crankshaft dais qhov kev txiav txim ntawm dabtsi yog khoov thiab torsional load. Yog li ntawd, lub crankshaft yuav tsum muaj lub zog txaus thiab nruj, thiab cov ntawv xov xwm saum npoo yuav tsum hnav-tiv taus, zoo ib yam thiab sib npaug.
Txhawm rau txo qhov loj ntawm lub crankshaft thiab lub zog centrifugal generated thaum lub sij hawm txav, cov ntawv xov xwm crankshaft feem ntau hollow. Txhua phau ntawv xov xwm saum npoo yog muab nrog lub qhov roj rau kev qhia txog roj lossis kev rho tawm kom lubricate cov ntawv xov xwm nto. Txhawm rau kom txo qis kev ntxhov siab, kev sib txuas ntawm lub caj dab spindle, tus pin crank thiab crank caj npab yog txuas nrog ib qho kev hloov pauv.
Lub luag hauj lwm ntawm crankshaft counterweight (tseem hu ua counterweight) yog kom sib npaug ntawm lub zog centrifugal thiab nws lub sijhawm, thiab qee zaum lub zog reciprocating inertial thiab nws lub sijhawm. Thaum cov rog thiab lub sijhawm lawv tus kheej sib npaug, qhov sib npaug ntawm qhov hnyav kuj tuaj yeem siv los txo cov load ntawm lub ntsiab bearing. Tus naj npawb, qhov loj thiab qhov chaw ntawm qhov sib npaug ntawm qhov hnyav yuav tsum tau txiav txim siab raws li tus naj npawb ntawm lub tog raj kheej ntawm lub cav, kev npaj ntawm lub tog raj kheej thiab cov duab ntawm lub crankshaft. Qhov sib npaug qhov hnyav feem ntau yog cam khwb cia lossis forged rau hauv ib qho nrog lub crankshaft, thiab lub zog loj diesel cav sib npaug qhov hnyav yog tsim los ntawm lub crankshaft thiab ces bolted ua ke.
Smelting
Tau txais kev kub siab thiab tsis tshua muaj sulfur ntshiab hlau yog tus yuam sij rau kev tsim cov hlau zoo. Cov khoom siv hauv tsev feem ntau yog raws li cupola, thiab cov hlau kub tsis yog kev kho mob ua ntej desulfurization; Qhov no yog ua raws li qhov tsawg purity npua hlau thiab cov coke tsis zoo. Molten hlau yog melted nyob rau hauv cupola, desulfurized sab nraum lub cub tawg, thiab ces rhuab thiab kho nyob rau hauv induction rauv. Hauv Suav teb, kev tshawb pom ntawm cov hlau molten muaj feem ntau tau ua los ntawm lub tshuab nqus tsev nyeem ntawv spectrometer.
molding
Cov txheej txheem huab cua cuam tshuam molding yog pom tseeb zoo dua rau cov txheej txheem av nplaum xuab zeb molding, thiab tuaj yeem tau txais high-precision crankshaft castings. Cov xuab zeb pwm tsim los ntawm cov txheej txheem no muaj cov yam ntxwv ntawm tsis muaj rebound deformation, uas yog tshwj xeeb tshaj yog ib qho tseem ceeb rau lub multi-throw crankshaft. Qee lub teb chaws crankshaft tuam ntxhab los ntawm lub teb chaws Yelemees, Ltalis, Spain thiab lwm lub teb chaws los qhia txog huab cua cuam tshuam cov txheej txheem molding, tab sis cov kev taw qhia ntawm tag nrho cov kab ntau lawm tsuas yog ib tug tsawg tsawg ntawm manufacturers.
Electroslag casting
Electroslag remelting thev naus laus zis yog siv rau kev tsim cov crankshaft, kom qhov kev ua tau zoo ntawm cam khwb cia crankshaft yuav piv rau cov forged crankshaft. Thiab muaj cov yam ntxwv ntawm kev loj hlob sai, kev siv hlau siab, cov khoom siv yooj yim, cov khoom ua tau zoo dua thiab lwm yam.
Forging tshuab
Cov kab tsis siv neeg nrog kub tuag forging xovxwm thiab hluav taws xob hydraulic rauj raws li lub ntsiab cav yog txoj kev loj hlob ntawm forging crankshaft ntau lawm. Cov kab ntau lawm no feem ntau yuav siv cov thev naus laus zis xws li precision txiav, yob forging (cross wedge dov) sib sau, nruab nrab zaus induction cua sov, xov hydraulic xovxwm xov, thiab lwm yam. Tib lub sijhawm, lawv tau nruab nrog cov cuab yeej pabcuam xws li kev tswj xyuas, conveyor. siv thiab pwm hloov cov cuab yeej coj rov qab mus rau lub turntable los tsim ib qho kev tsim khoom siv tau yooj yim (FMS). FMS tuaj yeem hloov pauv qhov chaw ua haujlwm thiab tuag thiab hloov kho qhov tsis sib xws, thiab ntsuas ntsuas tas li thaum lub sijhawm ua haujlwm. Tso saib thiab sau cov ntaub ntawv xws li forging thickness thiab siab tshaj plaws thiab sib piv nrog cov nqi ruaj khov los xaiv qhov zoo tshaj plaws deformation rau cov khoom zoo. Tag nrho cov txheej txheem yog saib xyuas los ntawm chav tswj hwm hauv nruab nrab, ua kom muaj kev ua haujlwm tsis muaj neeg siv. Lub crankshaft forged los ntawm txoj kev forging no muaj tag nrho cov fiber ntau ntawm cov hlau sab hauv, uas tuaj yeem ua rau qaug zog ntau dua 20%.
