Hauv -} qhov tob soj ntsuam ntawm pob ntsia hlau pob: los ntawm cov yam ntxwv rau kev xaiv ntawm txhua qhov {1} h} Hloov qhia
I. Kev qhia lus
Hauv daim teb ntawm kev kis tau tus mob, pob ntsia hlau ua cov tseem ceeb nrog cov khoom siv siab thiab cov khoom siv ntawm pob yog tus yuam sij los txiav txim siab nws qhov kev ua tau zoo. Cov pob ua los ntawm cov khoom sib txawv txawv nyob rau hauv cov nqe lus ntawm hardness, corrosion tsis kam thiab kev thov kev xaiv. Kab lus no yuav nkag siab txog cov yam ntxwv thiab kev sau cov cim ntawm cov ntaub ntawv capital, muab cov kev tshaj lij kev lag luam tsim qauv thiab kev tshaj tawm.
Thib ob, plaub tus tub ntxhais cov khoom siv thiab kev ua tau zoo
(1) Cov kabmob Hlau:"Tus Qauv Txheej Txheem" rau kev lag luam Industres.
Tus Thawj Sawv Cev:AISI 52100 (Cov neeg ua haujlwm hauv tsev GCR15)
Cov txiaj ntsig zoo:
Ultra - kev tawv tawv siab thiab hnav tsis kam:Hardness txog li 60 {- 64 hrc los ntawm quenching cov txheej txheem, haum rau lub tshuab ua haujlwm hnyav, siv tsheb sib txhuam uas xav tau kev sib txhuam ntev.
Precision machining muaj peev xwm: micron {{}}} roughness li tsawg dua lossis sib npaug ntawm 0.05μm, ua kom muaj kev sib luag thiab ruaj khov.
Tus nqi koj tau zoo -}}} Siv tau txiaj ntsig zoo: Kev ntsuas tus nqi thiab cov khoom siv ntawm kev xaiv rau General- lub hom phiaj machinery.
(2) Stainless Hlau: Txoj kev ib puag ncig ntawm "Tiv Thaiv Player"
1. Martensitic Stainless Hlau (xws li AISI 440C)
Rigid thiab hloov tau:Hardness ze rau bear steel (58-62 hrc), tab sis kuj muaj cov tshuaj tiv thaiv me me los yog xws li cov khoom noj me me, cov khoom siv kho mob).
Sib nqus rov ua haujlwm: Haum rau cov neeg kho tshuab cov qauv uas yuav tsum muaj hluav taws xob sib xyaw, xws li kis tau cov khoom siv hauv kev muaj cov khoom siv automation.
2. Austenitic Stainless hlau (piv txwv li AISI 316L)
Tsis - sib nqus thiab corrosion - tsis kam:Ua kiag li tsis - sib nqus thiab tiv thaiv cov khoom siv hluav taws xob muaj zog, thiab lwm yam xwm txheej hiav txwv
Tsawg - kub todlemness: tseem tswj hwm cov khoom siv zoo hauv {}} degree, thiab tuaj yeem siv rau aerospace qis {}} kub cov khoom kub.
(III) Cov Khoom Siv Tej Fais:"Lub tswv yim tsim kho" rau qhov siab - kev ua yeeb yam
1. Silicon Nitride (Si₃n₄)
Lub Hnav Tsho:Ntov ntawm tsuas yog 40% ntawm cov hlau, ua kom muaj zog txo lub sij hawm ntawm inertia, xws li cov khoom siv ceev ntawm kev sib txhuam yog li 0.001, cia roj {{free lubrication.
Lub Neej Lub Neej Ntev: Hardness ntawm 1500-2000 HV (2-3 zaug uas yog ntawm cov hlau), lub neej zoo tshaj plaws yog 3-5 zaug siab dua li cov pob zeb.
2. Zirconia (Zro₂)
(III) thermal stabilmark:coefficient ntawm thermal nthuav dav ze rau ntawm cov hlau, zoo thermal poob rauv, zoo} Kev kub}} {}} rhiab precision scenarios.
(D) tungsten carbide:"Hardcore xaiv" rau cov kev ua haujlwm hnyav
Huab tais ntawm super hardness thiab hnav tsis kam:Hardness txog 1800-2500 hv, ntau dua 3 zaug ntawm cov hlau, txawm tias nyob ib puag ncig, nws tuaj yeem tswj hwm qhov raug, thiab tus nqi hnav zoo li 0.0001 hli / 1000km.
Txwv:Kev kub siab (14.5g /M³) ua rau muaj siab inertia, thiab kim, feem ntau siv nyob rau hauv cov txiaj ntsig tshwj xeeb uas cov txiaj ntsig deb tshaj li cov neeg siv tshuab.
Thib peb, txoj cai golden ntawm cov khoom xaiv: Plaub {- Kauj ruam txiav txim siab {}}}}}}}}}
Thawj kauj ruam:Ntshiab Thauj Xwm
Lub teeb thauj / nruab nrab load: Qhov tseem ceeb bearing steel los yog stainless hlau (xws li cov khoom siv automation).
Hnyav Load / Kev Cuam Tshuam Ntaus: Xav txog tungsten carbide lossis siab {- Cov tshuab hnyav (xws li cov khoom siv hnyav, cov khoom siv tub rog).
Kauj ruam 2:Txheeb xyuas ib puag ncig ib puag ncig
Dry and clean environment: Bearing steel is the most cost-effective.
Ntub dej / cotricity corrosive ib puag ncig: stainless hlau (piv txwv li . 316 l) lossis ceramics (silicon nitride) muaj kev ntseeg siab dua.
Kev kub siab / Kev siab ceev cov xwm txheej: Cov ntaub ntawv sib ntaus (piv txwv li cov duab sib dhos (piv txwv li cov zirconia) yog ib qho yuav tsum tau ua.
Kauj ruam 3:Precision thiab kev ua kom ceev
Theem Precision Pov Tseg (± 1μm Theem): Cov Khoom Sib Ceramic lossis cov pob zeb polished stainless (smoother saum npoo av (smoother saum npoo av (smoother saum npoo av (smoother nto, tsawg txhuam).
High-speed transmission (>20M / min): Silicon nitride cov khoom pob muaj txiaj ntsig zoo dua vim lawv tus kheej qis dua thiab tus kheej {1} Lub cev muaj zog.
Kauj ruam 4:Nqi thiab Txij Nkawm Sib Luag
Luv -}} - tus nqi yuav tsum tau:Cov kabmob hlau (pib ua haujlwm qis dua, cov kev saib xyuas ib txwm).
Ntev -}} - kev xav tau kev xav tau:Ceramic lossis Tungsten carbide (tus nqi siab, tab sis lub neej ntev, muaj zog tsawg, ntau dua qhov ua tau zoo dua).
Thib plaub, txiav - ntug App dire thiab kev coj ua tshiab
Kev Tsim Khoom:Ib kab 12-nti wafer cov kab ntau lawm admts 316L, kev sib ntsib hauv chav kawm ua kom huv si lossis sib tham hauv chav kawm ua kom huv si lossis tsis muaj kev sib ntsib hauv chav kawm muaj kev cuam tshuam.
Lub Tsheb Tshiab:Silicon nitride cov khoom pob muaj nyob rau hauv cov hluav taws xob tsav, uas txo lub suab nrov ntawm lub iav los ntawm kev ua tau zoo los ntawm kev ua tau zoo los ntawm 3%, pab kom ua kom zoo ntawm cov hluav taws xob tsheb.
Aerospace:Cov khoom lag luam zirconia cov rooj sib xyaw hauv cov tshuab folding ntawm kev sib kis lub tsheb thauj mus los ntawm -40℃rau +80℃thiab hloov kho kom haum rau cov xwm txheej huab cua.
V. Xaus
Thaum xaiv cov khoom siv pob, nws yog ib qho tsim nyog los dhia tawm ntawm "ib qho kev ua tau zoo ua ntej" kev xav los ntawm lub nra, ib puag ncig, tus nqi, nqi thiab lwm qhov ntev. Nrog kev nce qib ntawm cov ntaub ntawv thev naus laus zis, tej hub thiab cov txheej txheem sib xyaw ua ke thev naus laus zis yog txhawb kev txhim kho ntawm pob screws rau "sib zog, ntau dua". Raws li tus neeg muab khoom siv tshaj lij, peb tuaj yeem muab cov kev pabcuam kev yoog raws li kev ua haujlwm kom haum, txhawm rau pab cov qhua tuaj yeem paub txog kev ua haujlwm ntawm tsav.
Nug tam sim no:Tau txais "pob khoom xaiv kev sib piv rooj", lossis teem sijhawm rau kev kuaj mob pub dawb rau kev hloov kho tshwj xeeb.
