Cov khoom siv yog ua los ntawm Daye hlau tshwj xeeb, thiab cov ntsiab lus ntawm cov khoom tsis huv (sulfur, oxygen, cov khoom tsis yog hlau) yog tsawg heev. Cov hlau kub siab thiab cov hlau carburized kuj tseem siv tau. Cov khoom siv muaj rau kev xaiv
2: Nce nqi yam tsis muaj nqi: cov nplhaib sab hauv thiab sab nraud ntawm cov kabmob tau tuab dua. Qhov hnyav ntawm cov kabmob nce ntxiv kom ntseeg tau tias cov kabmob ruaj khov. Tsis muaj nqi nce ntxiv
3: kev ua tiav qhov tseeb (txiav txim siab qhov du ntawm kev ua haujlwm)
Kev kam rau siab ntawm qhov ntev (txoj kab uas hla sab hauv, txoj kab uas hla sab nraud, dav): kev siv yog tus qauv ISO/ABEC, kev tswj tus nqi CpK zoo heev, kev teeb tsa yam tsis xaiv, kev teeb tsa ncaj qha, nrog tib qhov chaw sib txawv
Kev raug ntawm kev tig (lub zog): ntsuas qhov radial beat ntawm lub nplhaib sab hauv thiab qhov kawg ntawm lub ntsej muag. Tus nqi khiav tawm yog tswj hwm hauv qib micron, uas yog qhov tsim nyog rau kev kub ceev lossis kev ua tiav ntawm qhov chaw siab.
Roughness: Qhov roughness ntawm qhov chaw ntawm raceway thiab roller (Ra tus nqi). Peb siv cov txheej txheem superfine
Kev txhim kho vaj tse ntawm cov kabmob: Lub tsev ntawm cov kabmob tau raug txhim kho kom ntseeg tau tias qhov chaw sib cuag thiab qhov chaw quab yuam ntawm lub tsev ntawm cov kabmob thiab cov khoom siv tau raug nce ntxiv kom ntseeg tau tias lub tsev ntawm cov kabmob ruaj khov.
Plaub, kev tshem tawm thiab kev sib phim (txiav txim siab qhov kub thiab txias ua haujlwm thiab lub neej)
Qhov sib txawv tswj qhov ntau ntawm C3 qhov sib txawv, kev sib phim pab pawg
5. Suab nrov thiab kev co (txiav txim siab qhov zoo ntawm kev hnov) Tus nqi kev co (kev nrawm/ceev)
100% Anderon meter test, tshem tawm cov khoom uas muaj suab nrov.
Rau, kev kho cua sov thiab kev hloov kho qhov chaw (kev txiav txim siab ntawm kev hnav tsis kam)
Hardness thiab tob ntawm cov txheej hardened
Cov txheej txheem kho cua sov (xws li martensite, bainite quenching) ua kom muaj qhov nyuaj sib xws (HRC 61-65), thiab txheej tawv ua haujlwm tau zoo yog tob
Kev ruaj khov ntawm qhov ntev
Rau cov xwm txheej kub siab (xws li lub tshuab ziab khaub ncaws, lub cev muaj zog), peb ua cov kev kho mob tshwj xeeb kom ruaj khov, qhov loj ntawm cov kabmob yuav tsis hloov pauv ntau ntawm qhov kub siab, kom tiv thaiv kev xauv.
Xya, foob thiab lubrication
Peb cov roj sau (xws li ExxonMobil, Shell) thiab qhov ntim sau yog qhov tseeb, nrog rau kev ntsuas qhov hnyav thiab kev txhaj tshuaj rog (kom tsis txhob txhaj tshuaj rog tsis sib npaug ua rau kub taub hau)
Viii. Kev tiv thaiv ntim khoom:
