Xaiv qhov yogcov ntaub ntawv coj uayog ib qho ntawm cov kev txiav txim siab tseem ceeb tshaj plaws uas cov kws ua haujlwm ua thaum tsim cov tshuab txhim khu kev qha. Cov khoom siv txiav txim siab qhov nyuaj, kev tiv thaiv corrosion, lub peev xwm thauj khoom, lub neej qaug zog, thiab kev ua tau zoo tag nrho. Tsab xov xwm no piv ob qho ntawm cov ntaub ntawv siv dav tshaj plaws - hlau chrome thiab hlau stainless - los pab cov neeg siv xaiv qhov kev xaiv zoo rau lawv daim ntawv thov.
Hlau Chrome (GCr15 / SAE 52100)
Chrome hlau yog tus qauv thoob ntiaj teb rauchrome hlau bearings, muab qhov sib npaug zoo heev ntawm qhov nyuaj, lub peev xwm thauj khoom, thiab kev siv nyiaj tsim nyog. Nws cov pa roj carbon thiab chromium siab ua rau nws tuaj yeem ua kom tawv, ua rau nws tiv taus kev hnav zoo heev. Cov bearings no muab lub neej ntev qaug zog hauv qab cov khoom hnyav, ua rau lawv zoo tagnrho rau cov tshuab kis tsheb, cov cav, cov tshuab kev lag luam, thiab cov khoom siv dav dav. Qhov kev txwv tseem ceeb yog xeb: kev raug dej noo, tshuaj lom neeg, lossis cov chaw noo noo tuaj yeem txo qhov kev ua tau zoo tshwj tsis yog siv cov roj nplua nyeem thiab kev sib khi kom zoo.
Hlau tsis xeb (AISI 440C, 304)
Cov hlau tsis xeb raug xaiv thaum qhov kev tiv thaiv corrosion tseem ceeb dua li qhov siab tshaj plaws. Cov kabmob hlau tsis xeb ua los ntawm 440C muab qhov nyuaj zoo thiab lub neej qaug zog nruab nrab, thaum 304 stainless yog softer tab sis muaj kev tiv thaiv xeb zoo heev. Cov ntaub ntawv no vam meej hauv cov chaw uas muaj dej, cov neeg ua haujlwm ntxuav, pa dej, lossis cov tshuaj lom neeg - xws li kev ua zaub mov thiab dej haus, tshuaj, cov khoom siv kho mob, thiab cov khoom siv hauv hiav txwv. Txawm hais tias cov hlau stainless bearings kim dua thiab nqa cov ntsuas qaug zog qis dua me ntsis, lawv ua tau zoo dua li cov hlau chrome hauv cov chaw ib puag ncig hnyav.
Vim li cas 440C Hardness ≠ Chrome Steel Lub Neej Qaug zog
Txawm hais tias 440C stainless hlau tuaj yeem ncav cuag cov qib hardness zoo ib yam li chrome hlau, nws cov...kev nkees nkeesLub neej feem ntau qis dua vim muaj qhov sib txawv ntawm cov qauv me me. Cov hlau tsis xeb muaj ntau chromium thiab cov ntsiab lus ntxiv uas txhim kho kev tiv thaiv corrosion tab sis hloov pauv carbide faib. Cov carbides no tsis sib xws dua li cov hauv chrome hlau, ua rau muaj kev ntxhov siab ntau ntxiv nyob rau hauv cov khoom thauj rov ua dua. Yog li ntawd, 440C ua tau zoo tab sis tsis tuaj yeem phim tag nrho cov kev tiv thaiv kev qaug zog ntev ntawm qhov zoo tshaj plaws GCr15 / 52100.
Daim Ntawv Sib Piv Daim Ntawv Thov
Thaum ua ib qhokev xaiv kabmob, cov engineers yuav tsum sib npaug tus nqi, lub peev xwm thauj khoom, thiab cov xwm txheej ib puag ncig.
-
Hlau Chrome (GCr15 / 52100):Qhov zoo tshaj plaws rau kev thauj khoom siab, lub neej qaug zog siab, cov ntawv thov uas tsis muaj nqi.
-
Hlau tsis xeb (440C/304):Qhov zoo tshaj plaws rau cov dej noo, cov tshuaj lom neeg, cov khoom noj khoom haus, thiab kev raug dej hiav txwv.
Siv cov khoom siv kom raug yuav zam kev hnav ua ntej lub sijhawm, kev xeb, thiab lub sijhawm tsis ua haujlwm uas tsis tau xav txog.
Cov Kev daws teeb meem DEMY rau ob qho khoom siv
DEMY muaj ntau yam khoom sivDEMY bearingsHauv ob qho tib si chrome hlau thiab stainless hlau, npog cov kabmob sib sib zog nqus, cov kabmob kheej kheej, cov kabmob precision, thiab cov kev daws teeb meem tshwj xeeb. Peb pab neeg muab kev ntsuam xyuas kev txawj ntse raws li qhov hnyav, qhov ceev, ib puag ncig, thiab lub neej ntev kom ntseeg tau tias txhua tus neeg siv khoom tau txais kev xaiv cov khoom siv zoo tshaj plaws. Txawm hais tias koj xav tau kev ua haujlwm qaug zog siab tshaj plaws lossis kev tiv thaiv xeb zoo dua, DEMY xa cov khoom zoo sib xws, qhov tseeb siab txhawb nqa los ntawm daim ntawv pov thawj ISO / IATF16949 thiab kev tsim khoom siab heev.
