Los ntawm cov tsheb, cov tsheb ciav hlau khiav ceev, dav hlau mus rau cov twj paj nruag thiab cov cuab yeej siv tshuab, yuav luag txhua lub tshuab ua haujlwm tig tau pom nrog cov khoom siv sib txuam - bearings.Bearing steel, cov khoom siv xav tau rau kev tsim khoom ntawm cov kabmob, yog hu ua" huab tais ntawm hlau" vim tias nws ncaj qha cuam tshuam rau lub neej thiab kev ntseeg siab ntawm cov kabmob.
& quot; Qhov chaw ua haujlwm ntawm cov kabmob loj heev thiab qhov nyuaj, uas yuav tsum tsis tsuas yog muaj kev kub ceev thiab ruaj khov kev sib hloov, tab sis kuj muaj lub zog extrusion, kev sib txhuam, thiab txawm tias muaj qhov kub siab tshaj plaws."Professor Liu Dong tau hais qhia cov tub ceev xwm hais tias vim tias qhov no, qhov zoo thiab kev ntseeg tau ntawm cov kabmob hlau tau muaj kev txwv nruj heev.
Yuav ua li cas txhawm rau txhim kho qhov zoo ntawm cov kabmob hlau?Xib fwb Liu Dong qhia, ib qho yog rau sab hauv yog huv si txaus, qhov kev txuam nrog tsawg dua tsis zoo;Thib ob, nws yog teeb txaus, thiab cov lus hauv cov khoom yog me me thiab diffuse li sai tau.Txawm li cas los xij, nws muaj kev tu siab uas yog lub sijhawm ntev, qhov zoo ntawm cov kabmob hlau ua nyob rau hauv Suav teb muaj qhov sib txawv loj nrog thoob ntiaj teb qib siab.Coj cov ntawv suav ua piv txwv, qhov loj ntawm kev suav hauv cov khoom lag luam tawm txawv teb yog tsawg dua los sis sib npaug ntawm 10 microns, thaum qhov loj tshaj plaws nyob hauv Suav teb yog 50-52 microns," qhov loj me sib txawv npaum li 5 zaug [ GG] quot ;.
Vim tias nws tsis muaj peev xwm nrhiav tau cov kabmob zoo steel los ntawm cov tuam ntxhab, ntau lub chaw ua haujlwm yuav tsum them tus nqi siab rau kev ntshuam.Qhov no txhais tau tias peb yuav tsum tau yuav cov kabmob los ntawm txawv teb chaws txhua lub sijhawm peb tsim cov khoom tsim.
Raws li" lub teb chaws loj ntawm hlau" ;, Suav teb tuaj yeem ua li cas" lub tebchaws muaj zog hlau" ;?Tom qab xyoo kaum ntawm kev siv zog ntawm cov neeg tshawb nrhiav hauv Suav, cov teeb meem txuj ci xws li oxygen cov ntsiab lus thiab suav nrog rau cov kabmob hlau tau zoo daws.Xib fwb Liu Dong thiab nws pab neeg kuj tau daws qhov kawg&qhov kawg; teeb meem hauv kev lag luam -" carbide" ;.
Vim hais tias kev coj tus kheej cov hlau belongs rau cov pa roj carbon siab, nws cov ntsiab lus carbon ntau dua nyob hauv txhua tus hlau.Yog tias cov carbide faib tsis tau zoo thiab hauv cov chunks loj, qhov zoo yuav cuam tshuam loj.& quot; Nws' s zoo li kneading mov paj nrog tes ntawm ntsev," Liu hais." Yog tias lub khob noom cookie tsis tawg thiab ua kom sib luag, lub khob noom cookie yuav qab ntsev thiab nyuaj."Lub hom phiaj ntawm Liu' s pab pawg yog ua kom cov ntsev ntau tusyees faib rau hauv cov mij.
& quot; Los yog zuaj lub khob noom cookie ua piv txwv, qhov ntau dua qhov deformation koj paub, koj yuav ncau ntau dua, qhov tseem ceeb yog yuav ua li cas' knead'."Professor Liu Dong' s pab pawg muab tswv yim tshiab tso" muaj zog ua kom cov tshuab muaj zog" -" thev naus laus zis no thaum kneading qhov chaw, cia cov nplaim hauv peb cov lus qhia yog qhov txawv txav, thiab qhov deformation ntawm tus nqi yog qhov loj heev, tuaj yeem hais kom zuaj rau saum npoo kom huv thiab txoj kev muaj zog.
Nws suab lus yooj yim, tab sis nws muaj cov kev tshawb nrhiav tsis hnov lus ntawm cov xibfwb Liu Dong' s pab pawg.Pab neeg tau raug" sib tsoo rab ntaj kaum xyoo" ;. Tom qab tas li daws cov teeb meem tseem ceeb thiab sim ua tiav, pab pawg tau thaum kawg tawg los ntawm kev ua haujlwm hauv kev txheem, tsim 3" lub ntiaj teb thawj" thev naus laus zis thiab ua ntawv thov rau 66 lub tswv yim tsim.Lub zog loj spinning yog ib qho ntawm lawv.
Raws li kws lij choj Liu Dong, Tuam Tshoj' s cov kabmob kev lag luam tau tsim kev lag luam kev muag khoom ze li ntawm 200 txhiab yuan, thiab txhua xyoo kev loj hlob ntawm 12% -15%, tab sis cov khoom lag luam ntawm cov kabmob tseem yog feem ntau nyob rau hauv qes-tsawg kawg thiab cov kabmob me thiab nruab nrab.Ntawm lawv, cov tsheb tsav muaj txog li 40%. Kev tswjhwm zoo theem ntawm kev koom nrog thiab carbides hauv kev coj tus kheej steel hnyav cuam tshuam rau lub neej thiab kev cia siab ntawm cov tsheb maus taus hauv lub tsheb." Qhov tshwm sim ntawm cov tshuab muaj zog ntsig qeeb mentshis tuaj yeem hloov tau qhov xwm txheej no" ;.
Cov ntaub ntawv kuaj pom tias qhov luaj li cas cov noob qoob loo raug txo los ntawm 50 microns rau 10 microns los ntawm lub tshuab kev muaj zog loj, thiab cov carbide loj tau txo los ntawm 10 zaug xwb.Dais lub hardness steel tib lub sijhawm zoo heev txhim kho, hauv lub ntiaj teb' s qib sab saum toj.Tsis tas li ntawd, lub neej thiab kev ntseeg ntawm cov bearings tau zoo dua.Lub thev naus laus zis tseem tuaj yeem txhim kho qhov ua tau zoo ntawm cov khoom siv thiab ua kom lub sij hawm ua tiav ntau lawm.(Tau qhov twg los: Tuam Tshoj Cov Hluas Hnub Txhua Hnub)
