Ntev npaum li cas Bearings tuaj yeem ua haujlwm?

Nyob rau hauv cov nqe lus ntawm ntim, bearings tsis suav hais tias loj Cheebtsam nyob rau hauv hluav taws xob motors, tab sis lawv yog cov "pob qij txha" thiab "load-cov kabmob phab ntsa" ntawm hluav taws xob motors. Nws ncaj qha txiav txim siab kev khiav hauj lwm efficiency, stability, thiab lifespan ntawm lub cev muaj zog.
Bearings tsuas yog cov ntsiab lus txhawb nqa ntawm lub ncej, bearing qhov hnyav ntawm lub rotor nws tus kheej nrog rau cov radial thiab axial rog kis los ntawm txoj siv sia thiab lub zog. Nws xyuas kom meej tias lub rotor tuaj yeem 'hover' ntawm qhov chaw ntawm lub stator, tsis yog ncaj qha rub tawm ntawm lub casing.
Electric motor bearings tsis muaj qhov ruaj khov "lub neej txee", thiab lawv lub neej ntev nyob ntawm tus qauv tsim thiab kev ua haujlwm tiag tiag. Raws li kev tsim qauv zoo tagnrho, lub neej ua haujlwm feem ntau yog nyob ntawm 20000 txog 40000 teev (kwv yees li 2.3 txog 4.5 xyoo ntawm kev ua haujlwm tas mus li) raws li kev siv; Tab sis hauv kev ua haujlwm hnyav, nws yuav luv li ob peb txhiab teev lossis luv dua. Feem ntau siv "lub neej nyob" hauv kev lag luam bearing yog hais txog lub sijhawm ua haujlwm (L10) uas 90% ntawm cov kabmob tuaj yeem ncav cuag ua ntej qaug zog spalling tshwm sim.

(Ceeb Toom: Cov txiaj ntsig saum toj no yog cov kev ntsuas theoretical nyob rau hauv cov qauv thauj khoom thiab lubrication zoo, thiab qhov tseeb lifespan feem ntau fluctuates vim muaj ntau yam.)
Bearings yog tib yam tseem ceeb hauv cov motors uas tuaj yeem tiv taus ob qho tib si thiab thermal stresses ib txhij. Nws lub xeev ncaj qha txiav txim siab siv lub zog, suab nrov, thiab kev ntseeg siab ntawm lub cev muaj zog.
Yog hais tias koj yuav ib tug standard industrial motor,cov kabmob feem ntau tuaj yeem ua haujlwm rau 3-5 xyoos nyob rau hauv ib txwm thauj khoom, ib puag ncig huv, thiab kev saib xyuas tsis tu ncua; Tab sis yog tias cov kev ua haujlwm hnyav (xws li kub siab, plua plav, nquag pib nres), lub neej yuav luv luv kom tsawg dua 1 xyoos.
Thaum kawg, thov ceeb toom ntawm peb cov hnub so Lub Tsib Hlis yuav los tom ntej (01/05/2026-05/05/2026). Xav kom sawv daws nyob kaj siab lug.
