Cov khoom ntawm bearing steel

Raws li kev ua haujlwm ib puag ncig thiab kev puas tsuaj tshuaj xyuas ntawmbearing steel, bearing steel yuav tsum muaj cov khoom hauv qab no:

1. Kev tiv tauj siab qaug zog thiab compressive zog;

2. Cov kabmob steel yuav tsum muaj qhov siab thiab tsis sib xws tom qab kev kho cua sov (tseem ceeb bearing steel hardness yuav tsum tau rau HRC61 ~ 65);

3. Siab elastic txwv kom tsis txhob muaj cov yas deformation ntau dhau ntawm cov kabmob steel nyob rau hauv siab load;

4. Tej yam toughness los tiv thaiv bearing puas nyob rau hauv tej load;

5. Kev ruaj ntseg zoo, tiv thaiv cov kabmob hauv lub sijhawm ntev los yog siv vim qhov hloov pauv loj thiab txo qhov raug;

6. Tej yam corrosion kuj, nyob rau hauv cov huab cua thiab lubricant yuav tsum tsis yooj yim rau xeb los yog corrosion, ua kom lub nto luster;

7. Kev ua tau zoo ntawm cov txheej txheem, xws li txias, kub sib sau ua haujlwm, txiav kev ua haujlwm, kev sib tsoo kev ua haujlwm, kev kho cua sov txheej txheem kev ua haujlwm thiab lwm yam, txhawm rau hloov mus rau qhov ntau, kev ua haujlwm siab, kev xav tau ntau lawm. Muaj cov kev cai sib txawv rau cov kabmob raws li kev ua haujlwm tshwj xeeb. Xws li kub tsis kam, corrosion kuj, cuam tshuam tsis kam, antimagnetic thiab lwm yam.

Kev sib cuag qaug zog lub neej ntawm bearings yog tshwj xeeb tshaj yog rhiab heev rau lub inhomogeneity ntawm cov qauv thiab cov khoom ntawm steel. Yog li ntawd, ib tug series ntawm yuav tsum tau npaj rau lub koom haum nyob rau hauv kev siv thiab thawj lub koom haum. Lub microstructure ntawm bearing steel nyob rau hauv kev pab cuam yuav tsum tau muab sib npaug zos rau cov nplua carbide ntawm tempered martensite matrix. Xws li microstructure tuaj yeem muab cov kabmob steel rau cov khoom xav tau. Muaj ob lub ntsiab lus tseem ceeb rau cov qauv qub: ib qho yog ntshiab, hais txog cov ntsiab lus ntawm impurity ntsiab thiab suav nrog hauv cov hlau kom tsawg; Qhov thib ob yog cov qauv tsis sib xws, uas txhais tau hais tias cov khoom tsis yog xim hlau suav nrog thiab carbides hauv cov hlau yuav tsum tau zoo dispersed thiab sib npaug. Yog li cov purity ntawm steel thiab cov uniformity ntawm cov qauv yog ob lub ntsiab teeb meem ntawm metallurgical zoo ntawm bearing steel.
