Sib nqus bearings yog ib hom kabmob uas siv cov hlau nplaum ruaj khov lossis electromagnets los muab cov hlau nplaum sib nqus rau cov tshuab tig. Lub bearings cia siab rau lub zog ntawm repulsion los yog attraction ntawm magnetic teb los tsim ib tug uas tsis yog-hu rau kev pab txhawb nqa rau lub rotating ncej. Los ntawm kev tshem tawm cov kev xav tau ntawm cov khoom siv kho tshuab ib txwm muaj, cov kabmob sib nqus muaj qhov txo qis kev sib txhuam, txo qhov hnav thiab tsim kua muag, thiab ua kom muaj kev ua haujlwm zoo.
Cov hlau nplaum tas mus li siv cov hlau nplaum muaj zog ua haujlwm ruaj khov los tsim cov hlau nplaum uas nyiam los yog ua rau cov hlau nplaum sib nqus. Lawv muaj txiaj ntsig zoo rau cov tshuab ua haujlwm siab uas yuav tsum muaj kev tswj xyuas tsawg kawg nkaus. Vim tias cov hlau nplaum ruaj khov, lawv tsis tas yuav muaj hluav taws xob los tswj cov hlau nplaum, ua rau lawv muaj kev ntseeg siab heev thiab tsis muaj kev saib xyuas zoo.
Electromagnetic bearings, ntawm qhov tod tes, siv cov khoom siv hluav taws xob los tsim ib qho chaw sib nqus uas tuaj yeem tswj tau qhov tseeb. Hom kabmob no muaj txiaj ntsig zoo rau cov tshuab qis qis uas yuav tsum tau muaj kev tswj xyuas siab thiab qhov tseeb. Qhov chaw sib nqus tuaj yeem tswj tau los ntawm kev kho cov tam sim no rau cov electromagnets. Qhov no tso cai rau kev hloov kho ntawm lub sijhawm tiag tiag thiab ua rau cov kabmob electromagnetic haum rau ntau yam kev siv, suav nrog kev tsim precision thiab kev tshawb fawb.
Diamagnetic bearings yog ib hom magnetic bearings uas siv lub repulsion ntawm magnetic teb los muab levitation. Tsis zoo li cov kabmob sib nqus ib txwm siv, uas siv cov hlau nplaum sib nqus zoo nkauj, cov kabmob no siv lub zog ntawm cov hlau nplaum sib nqus. Cov ntaub ntawv diamagnetic, xws li graphite los yog bismuth, yog siv los tsim ib qho chaw sib nqus uas yog repelled los ntawm lub rotor. Qhov no tsim kom muaj kev tswj hwm kev ua haujlwm uas tuaj yeem hloov kho kom meej qhov chaw.
Kev siv cov kabmob sib nqus muaj ntau yam txiaj ntsig tshaj li cov khoom siv kho tshuab. Txo kev sib txhuam, txo qhov hnav thiab tsim kua muag, thiab nce kev ua tau zoo tsuas yog qee qhov zoo. Tsis tas li ntawd, cov kabmob sib nqus yog qhov zoo tagnrho rau siv rau hauv qhov hnyav lossis qhov chaw muaj kev phom sij, qhov twg cov kabmob ib txwm tsis haum. Sib nqus bearings tau siv ntau yam kev siv, suav nrog kev kub ceev centrifuges, lub tshuab nqus tsev twj, thiab turbochargers.
Hauv kev xaus, sib nqus bearings yog ib qho kev daws teeb meem tshiab thiab muaj txiaj ntsig zoo rau kev sib hloov tshuab, muab ntau yam txiaj ntsig tshaj li cov khoom siv kho tshuab. Los ntawm kev siv cov hlau nplaum ruaj khov lossis electromagnets, cov kabmob no muab cov kev pabcuam tsis sib cuag uas txo cov kev sib txhuam, txo qhov hnav thiab tsim kua muag, thiab ua kom muaj txiaj ntsig zoo. Nrog rau kev siv xws li los ntawm kev kub ceev centrifuges mus rau precision manufacturing, magnetic bearings tseem ua lub luag haujlwm tseem ceeb hauv cov cuab yeej siv niaj hnub no.
