Niaj hnub no, tus editor yuav piav qhia rau koj: tsib yam ntxwv tseem ceeb ntawm spherical roller bearings. Rau spherical roller bearings, yog tias dov kev sib txhuam tshwm sim thaum siv, nws yuav ua nrog zawv zawg kev sib txhuam, uas yuav ua rau kom muaj kev coj tus kheej. Txhawm rau tiv thaiv lossis txo cov kabmob hnav thiab tswj kom muaj kev ruaj ntseg siab, lub hauv paus yog xaiv High hardness, muaj zog xeb tsis kam, siab hnav tsis kam, tiv taus qaug zog, thiab cov txheej txheem ua haujlwm kuj yog thawj chav kawm. Cov xwm txheej no yog qhov kev ua tau zoo ntawm cov kheej kheej kheej kheej bearings.
1. Thaum siv cov kabmob kheej kheej kheej kheej, lub hardness ntawm cov kabmob yog ib qho ntawm cov ntsiab lus tseem ceeb ntawm tag nrho cov kabmob zoo. Nyob rau hauv tus txheej txheem ntawm kev siv, lub hardness ntawm cov kabmob yuav tsum ncav cuag HRC58 ~ 63 feem ntau, thiaj li ua tau zoo dua cov kev xav tau. Tsis tas li ntawd, nws muaj ib tug loj elastic tsis nyob rau hauv cov nqe lus ntawm high-lub zog tiv tauj qaug zog thiab hnav tsis kam.
2. Txhawm rau tiv thaiv cov kabmob los ntawm xeb thaum siv cov kabmob, tshwj xeeb tshaj yog thaum cov kabmob thiab cov khoom tiav tau ua tiav lossis khaws cia, cov kabmob hlau uas muaj xeb kuj yuav tsum tau xaiv.
3. Thaum siv spherical roller bearings, ib yam uas feem ntau mob taub hau yog qhov hnav tsis kam ntawm cov kabmob, thiab kev hnav tsis kam kuj yog ib lo lus nug feem ntau nug los ntawm cov neeg siv thaum yuav cov bearings, uas feem ntau yog vim lub nplhaib bearings, dov. Rolling kev sib txhuam thiab zawv zawg kev sib txhuam feem ntau tshwm sim ntawm lub cev thiab lub tawb thaum siv, thiab kev sib txhuam, raws li tau hais thaum pib, tsis tuaj yeem ua tiav qhov kev xav tau vim qhov tsis ruaj tsis khov ntawm cov kabmob. Kev puas tsuaj yuav tsum tau ua nyob rau hauv kev xaiv ntawm bearing steel, thiab ib tug uas muaj zog hnav kuj yuav tsum tau xaiv.
4. Vim li cas koj thiaj xav txhim kho lub neej kev pab cuam ntawm kheej kheej cov menyuam bearings? Feem ntau vim hais tias nyob rau hauv tus txheej txheem ntawm kev siv: cov kabmob yuav yooj yim ua rau kev puas tsuaj tom qab kev sib cuag nrog tus nto nyob rau hauv qhov kev txiav txim ntawm cyclic load, thiab txawm ua rau tawg thiab spalling. Cov menyuam bearings yuav tsum tau xaiv nrog muaj zog tiv tauj qaug zog, thiaj li ua tau zoo rau lub neej ntev.
5. Ntxiv nrog rau cov lus hais saum toj no, kev ua haujlwm ntawm cov kheej kheej kheej kheej bearings yuav tsum tau tswj nruj me ntsis, uas tseem yuav tsum tau ua kom zoo, kev ua haujlwm siab thiab cov kev cai loj, feem ntau yog vim qhov xav tau los ntawm ntau yam txheej txheem thaum lub sijhawm. Kev ua, xws li: Kub thiab txias ua, txiav thiab quenching txheej txheem yuav tsum tau tswj kom thiaj li tsim tau zoo kheej kheej cov menyuam bearings.
Ib feem ntawm cov ntaub ntawv yog los ntawm Is Taws Nem, thiab siv zog ua kom muaj kev nyab xeeb, raws sijhawm, thiab raug. Lub hom phiaj yog xa cov ntaub ntawv ntau ntxiv, thiab nws tsis txhais hais tias nws pom zoo nrog nws cov kev xav lossis lub luag haujlwm rau nws qhov tseeb. Yog tias cov ntaub ntawv rov luam tawm ntawm lub vev xaib no cuam tshuam txog kev cai lij choj thiab lwm yam teeb meem, thov hu rau lub vev xaib no kom lub sijhawm tshem tawm.
