Kev Txhim Kho ntawm Cov Khoom Siv Dov Bearing
In dov kabmobKev tsim khoom, cov khoom siv ncaj qha txiav txim siab lub neej ntawm cov kabmob, kev ntseeg tau, thiab cov xwm txheej ua haujlwm. Tam sim no, cov khoom siv kabmob tseem feem ntau yog ua los ntawm cov hlau chromium siab, xws li GCr15 thiab GCr15SiMn. Nyob rau hauv xyoo tas los no, nrog rau kev txhim kho cov khoom siv rau kev ceev dua, cov khoom hnyav dua, qhov kub siab dua, thiab cov xwm txheej ua haujlwm nyuaj dua, cov ntaub ntawv kabmob kuj tseem niaj hnub hloov kho, feem ntau qhia cov lus qhia hauv qab no:
1. Cov Hlau Uas Muaj Peev Xwm Ua Tau Siab
Yuav kom ua tau raws li qhov xav tau ntawm cov khoom loj thiab tuab, kev lag luam tau maj mam tsim cov hlau bearing uas muaj zog heev, xws li GCr15SiMo thiab GCr18Mo. Cov ntaub ntawv no tuaj yeem tau txais cov qauv tawv sib xws ntawm qhov loj dua, txhim kho lub zog tag nrho thiab lub neej qaug zog ntawm cov khoom, thiab tsim nyog rau cov bearings loj thiab cov khoom siv hnyav.
2. Cov Hlau Uas Muaj ...
Cov hlau GCr4 uas tawv nto feem ntau siv rau hauv cov khoom siv hnyav xws li tsheb ciav hlau thiab cov tshuab dov. Los ntawm kev siv cua sov nruab nrab zaus thiab txias sai, ib txheej tawv ntawm qee qhov tob tuaj yeem tsim rau ntawm qhov chaw ntawm cov khoom, ua rau cov kabmob muaj ob qho tib si tawv nto thiab tawv plawv siab, yog li txhim kho kev tiv taus qaug zog thiab kev tiv taus kev cuam tshuam.
3. Cov Hom Tshiab ntawm Cov Hlau Stainless Steel Bearing Steel
Cov hlau tsis xeb ib txwm muaj xws li 9Cr18 thiab 9Cr18Mo (440C) muaj kev tiv thaiv xeb zoo, tab sis lawv yooj yim tsim cov carbides ntxhib, cuam tshuam rau lub neej qaug zog thiab qhov zoo ntawm qhov chaw. Cov hlau tsis xeb martensitic 0.7C-13Cr tsim nyob rau xyoo tas los no, los ntawm kev txo cov pa roj carbon thiab chromium thiab txo cov carbides eutectic, txhim kho kev ua haujlwm qaug zog, kev tawv, thiab kev tiv thaiv xeb ntawm cov bearings. Nws feem ntau siv rau hauv cov bearings precision xeb-proof, xws li hard drive bearings thiab cov khoom siv kho mob bearings.
4. Cov Hlau Alloy Muaj Zog Siab
GT series bearing steels, los ntawm kev ua kom zoo tshaj plaws alloy composition, txhim kho matrix lub zog thiab toughness thiab txhim kho tempering stability. Haum rau cov qauv bearing hnyav lossis lub teeb yuag, lawv muaj lub neej ua haujlwm zoo nyob rau hauv cov xwm txheej lubrication huv.
5. Cov Hlau Uas Tiv Thaiv Kev Ua Phem
Hauv kev siv tiag tiag, cov hmoov av lossis cov khoom hnav hauv cov roj nplua nyeem tuaj yeem tsim cov qhov rau ntawm qhov chaw ntawm cov kabmob, ua rau muaj kev ntxhov siab thiab kev qaug zog ua ntej lub sijhawm. Txhawm rau daws qhov teeb meem no, Nyiv Pooj tau tsim TF series ntawm cov hlau tsis muaj kuab paug (xws li TF, HTF, STF, NTF, thiab lwm yam).
Los ntawm kev ua kom zoo dua cov ntsiab lus carbon thiab cov khoom sib xyaw ua ke, cov khoom siv tsim cov carbides zoo dua thiab ua rau cov austenite khaws cia ntau dua, yog li txo qhov kev ntxhov siab ntawm cov npoo indentation. Kev paub dhau los qhia tau hais tias cov bearings ua nrog TF series steels tuaj yeem muaj lub neej ntev dua 4-10 npaug hauv qab cov xwm txheej roj nplua nyeem.
6. Quasi-High-Kub Bearing Steel
Thaum cov bearings GCr15 ib txwm siv rau hauv qhov chaw ib puag ncig txij li 100 ℃ txog 200 ℃, qhov "cheeb tsam dawb ci" uas tsis muaj zog yooj yim tsim rau ntawm txheej hauv qab ntawm cov khoom siv, yog li txo lub neej ntawm cov kabmob. Txhawm rau daws qhov teeb meem no, cov hlau bearing kub quasi-high-temperature xws li NTJ2 thiab KUJ7 tau tsim. Los ntawm kev nce cov ntsiab lus ntawm cov ntsiab lus xws li Cr, Si, thiab Mo, kev tsim cov cheeb tsam dawb ci raug txwv, tso cai rau cov bearings kom tswj tau lub neej zoo thiab qhov ruaj khov txawm tias ntawm 150 ℃.～180 ℃. Cov ntaub ntawv no siv dav hauv cov cav tsheb, cov tshuab hluav taws xob, thiab cov khoom siv ua haujlwm kub.
7. Cov Hlau Uas Kub Thiab Txias
Hauv qhov kub thiab txias thiab ceev ceev xws li aerospace, cov ntaub ntawv ib txwm tsis txaus. Cov hlau bearing kub thaum ntxov xws li T1, T2, T10, thiab M50, thaum muaj qhov kub thiab txias siab, muaj cov ntsiab lus alloy siab thiab tus nqi siab.
Nyob rau xyoo tas los no, Tebchaws Europe thiab Tebchaws Meskas tau tsim cov hlau carburizing tshiab uas kub thiab txias, xws li M50NiL, CBS1000, thiab RBD. Ntawm lawv, M50NiL yog cov siv dav tshaj plaws. Tom qab carburizing, cov carbides zoo tsim rau ntawm qhov chaw, tsim kev ntxhov siab compressive seem. Nws lub hauv paus toughness tuaj yeem ncav cuag 2.5 npaug ntawm M50, ua rau lub neej qaug zog dua. Tam sim no, nws feem ntau yog siv rau hauv cov khoom siv high-end xws li aero-engine main shaft bearings. Zuag qhia tag nrho, kev tsim cov ntaub ntawv dov bearing txuas ntxiv mus rau qhov muaj zog dua, kev ntseeg siab dua, kev tiv thaiv kev ua qias tuaj, kev tiv thaiv corrosion, thiab kev ua haujlwm kub siab. Nrog rau kev tsim kho aerospace, cov khoom siv zog tshiab, thiab kev tsim khoom siab, kev tshawb fawb thiab kev siv cov ntaub ntawv bearing tshiab yuav txuas ntxiv mus tob dua, muab kev txhawb nqa kev siv tshuab zoo dua rau kev txhim kho kev ua haujlwm bearing.
