Gear castings tseem hu ua cam khwb cia hlau iav.
Qhov no yog vim feem ntau cov iav yog ua los ntawm cam khwb cia hlau.
Ntawm no, kuv qhia qee cov ntaub ntawv hais txog kev tsim cov iav castings thiab lwm yam kev kho cua sov.
Qhov hnyav ntawm iav castings feem ntau yog los ntawm ob peb kilograms mus rau ob peb tons.
Gear castings feem ntau yog siv high-carbon cam khwb cia hlau, thiab qee cov hlau alloys uas muaj chromium, npib tsib xee, thiab molybdenum yog siv los ua kom muaj zog tensile siab.
Feem ntau, cov iav loj muaj qhov xav tau ntawm lub cev qis dua li cov iav me me.
Hais txog cov txheej txheem casting, feem ntau cov txheej txheem molding hauv pem teb yog qhov tsim nyog thiab tuaj yeem ua tau raws li qhov yuav tsum tau ua.
Raws li rau cam khwb cia steel zog, xws li tsav gears, gears thiab idlers, pem teb molding txheej txheem siv quartz xuab zeb yog ib qho kev xaiv zoo. Vim li cas, vim tias feem ntau ntawm cov iav yuav tsum tau ua tiav.
Yog li ntawd, koj tsis tas yuav siv cov txheej txheem casting ntau dua. Tsis tas li ntawd, rau nruab nrab thiab loj steel castings, cov txheej txheem molding hauv pem teb siv quartz xuab zeb yog yuav luag tib txoj kev xaiv.
Hais txog kev kho cua sov, tau kawg, tag nrho cov hlau castings yuav tsum tau ua raws li tus qauv kom tshem tawm cov siab sab hauv.
Qee qhov ntawm cov iav casting tuaj yeem welded. Yog hais tias lub foundry welds castings, welding txoj hauj lwm yuav tsum tau annealed.
Yog hais tias lub hardness yog siab heev tom qab hobbing, koj muaj peev xwm re-anneal kom txo cov hardness thiab tshem tawm cov sab hauv hard me ntsis.
Tom qab machining thiab hobbing, lub iav yog quenched los yog hu ua hardening kev kho mob kom cov nto hardness ntawm cov iav hniav.
Rau cov iav me me, koj tuaj yeem ua kev kho carburizing. Rau lub zog tsav loj, koj tuaj yeem ua kev kho deg hardening.
Lub iav lub neej tsis muaj kev kho hardening yog luv heev, tsuas yog ob peb lub lis piam mus rau ob peb lub hlis.
Vim tias cov iav castings muaj qhov xav tau ntau dua rau cov khoom siv, qhov tsis xws luag, kev ua haujlwm thiab kev kho cua sov.
Ntxiv mus, tus naj npawb ntawm kev txiav txim rau iav castings kuj tsawg. Yog li ntawd, ntau lub tuam txhab steel tsis kam tsim khoom.
Qee lub zog yog tsim los ntawm cov txheej txheem forging. Cov qauv sab hauv ntawm cov iav forged muaj qhov ntom ntom zoo dua thiab muaj zog dua.
Forged iav tuaj yeem siv rau hauv kev ua haujlwm nruj dua. Cam khwb cia iav muaj lub zog tsawg, tab sis tau siv dav hauv kev ua haujlwm dav dav.
Tus nqi ntawm forging gears yog siab, thaum tus nqi ntawm casting gears kuj tsawg. Tus neeg yuav khoom yuav tsum xaiv cov txheej txheem tsim khoom tsim nyog raws li tus nqi thiab kev siv.
