Covlub cev muaj zogncej yog hollow, nrog zoo tshav kub dissipation kev ua tau zoo thiab tuaj yeem txhawb nqa lub teeb yuaglub cev muaj zog.Yav dhau los, lub cev muaj zog shafts feem ntau yog khoom, tab sis vim yog kev siv lub cev muaj zog, qhov kev ntxhov siab feem ntau yog nyob rau saum npoo ntawm cov ncej, thiab qhov kev ntxhov siab ntawm lub hauv paus tseem me me. Raws li kev khoov thiab torsional zog ntawm cov khoom siv mechanics, sab hauv ntawm lublub cev muaj zogncej tau tsim nyog hollowed tawm, thiab tsuas yog ib lub me me sab nraud txoj kab uas hla yog yuav tsum tau nce rau sab nraud. Lub hollow ncej tuaj yeem ua tau raws li qhov kev ua tau zoo thiab ua haujlwm raws li cov khoom siv, tab sis nws qhov hnyav tuaj yeem txo qis. Meanwhile, vim lub hollowing ntawm lublub cev muaj zogncej, cov roj txias tuaj yeem nkag mus rau sab hauv ntawm lub cev muaj zog, ua kom cov cua sov dissipation thaj tsam thiab txhim kho cov cua sov dissipation efficiency. Raws li cov qauv tam sim no ntawm 800V high-voltage fast charging, qhov zoo ntawm hollow motor shafts yog ntau dua. Txoj kev tsim khoom tam sim no rau hollow motor shafts feem ntau suav nrog cov khoom siv hollowing, vuam, thiab kev sib xyaw ua ke, ntawm cov vuam thiab kev sib xyaw ua ke tau siv dav hauv kev tsim khoom.
Lub welded hollow ncej yog tsuas yog ua tiav los ntawm extrusion txoj kev ua kom tiav ib kauj ruam hauv lub qhov ntawm lub ncej, thiab ces machined thiab welded rau hauv cov duab. Los ntawm extrusion molding, cov duab hloov ntawm lub puab lub qhov nrog cov khoom qauv thiab lub zog yuav tsum tau khaws cia kom ntau li ntau tau. Feem ntau, cov phab ntsa tuab ntawm cov khoom tuaj yeem tsim hauv qab 5 hli. Cov cuab yeej siv vuam feem ntau siv cov pob tw txhuam vuam lossis laser vuam. Yog siv lub pob tw welding, txoj hauj lwm ntawm lub pob tw yog feem ntau txog 3 hli vuam protrusion. Siv laser vuam, vuam qhov tob yog feem ntau ntawm 3.5 thiab 4.5 hli, thiab vuam lub zog tuaj yeem lav tau ntau dua 80% ntawm cov substrate. Qee cov neeg muag khoom tuaj yeem ua tiav ntau dua 90% ntawm lub zog substrate los ntawm kev tswj cov txheej txheem nruj. Tom qab vuam ntawm lub hollow ncej tiav, nws yog ib qho tsim nyog yuav tsum tau ua ultrasonic los yog X-ray kuaj ntawm microstructure thiab vuam zoo ntawm qhov vuam cheeb tsam kom ntseeg tau cov khoom sib xws.
Kev sib sau ua ke hollow ncej feem ntau yog forged los ntawm cov khoom siv sab nraud ntawm qhov khoob, ua rau sab hauv kom ncaj qha mus rau qhov chaw sab hauv ntawm lub ncej. Tam sim no, radial forging thiab teb forging yog tsuas yog siv, thiab cov cuab yeej yog mas imported. Cov radial forging yog ib yam ntawm FELLS lub tuam txhab cov cuab yeej, thaum lub sij hawm teb forging yog ib yam ntawm GFM tuam txhab cov cuab yeej. Radial forging txoj kev yog feem ntau ua tiav los ntawm kev siv plaub los yog ntau tshaj symmetrical rauj ntawm ib zaus ntawm ntau tshaj 240 tshuab ib feeb kom ua tiav me me deformation ntawm qhov dawb paug thiab ncaj hollow raj dawb paug txoj kev. Rotary forging forming yog cov txheej txheem ntawm kev sib npaug ntawm ntau lub taub hau rauj nyob rau hauv cov kev taw qhia ncig ntawm lub billet. Lub taub hau rauj tig ib ncig ntawm lub axis thaum ua cov radial high-frequency forging ntawm lub workpiece, txo qhov cross-sectional loj ntawm lub billet thiab ncua axially kom tau lub workpiece. Piv rau cov khoom siv ib txwm muaj, cov nqi tsim khoom ntawm kev sib xyaw ua ke hollow shafts yuav nce li ntawm 20%, tab sis qhov hnyav ntawm lub cev muaj zog feem ntau yuav raug txo los ntawm 30-35%.
