Kev sib cuag zoo qaug zog ntawm lub puab kheej kheej bearing nrog lub rooj zaum yog qhov cuam tshuam ntawm kev sib hloov kev ntxhov siab ntawm cov kabmob ua haujlwm lub npe, thiab qhov sib sib zog nqus tev yog qhov ua rau sab hauv ntawm kev sib cuag zoo.Spherical roller bearings yog sib sau ua ke nrog lub nruas-zoo li tus menyuam bearings ntawm lub nplhaib puab nrog ob lub raceways thiab lub nplhaib sab nraud nrog spherical raceways.Spherical roller bearings muaj ob kab ntawm cov menyuam, uas feem ntau dais radial loads, tab sis kuj tuaj yeem dais axial loads hauv txhua qhov kev taw qhia.Nrog siab radial load peev xwm, nws yog tshwj xeeb tshaj yog haum rau ua hauj lwm nyob rau hauv hnyav load los yog kev co load, tab sis nws tsis tuaj yeem dais ntshiab axial load.Lub nplhaib sab nrauv ntawm cov kabmob no yog kheej kheej, yog li nws txoj kev sib dhos ua haujlwm zoo, thiab nws tuaj yeem them nyiaj rau qhov yuam kev concentricity.

Peb paub tias kev sib cuag qaug zog spalling tshwm sim nyob rau hauv lub npe ua hauj lwm ntawm lub puab kheej kheej bearing nrog lub rooj zaum, thiab feem ntau yog nrog los ntawm qaug zog tawg.Ua ntej, nws tshwm sim los ntawm qhov siab tshaj plaws alternating shear stress hauv qab no lub npe hu, thiab ces nthuav mus rau txawv spalling duab, xws li dots.Pitting los yog pitting peeling, tev rau hauv me me flakes yog hu ua ntiav tev.Vim tias maj mam nthuav dav ntawm qhov chaw spalling, nws feem ntau nthuav mus rau txheej txheej sib sib zog nqus, sib sib zog nqus spalling.

Abrasion effect yog hais txog cov nyhuv uas zawv zawg kev sib txhuam ntawm cov npe ua rau cov hlau nominal ntawm lub npe ua haujlwm tau hnav tawm txhua lub sijhawm.Spherical roller bearings yog sib sau ua ke nrog lub nruas-zoo li tus menyuam bearings ntawm lub nplhaib puab nrog ob lub raceways thiab lub nplhaib sab nraud nrog spherical raceways.Spherical roller bearings muaj ob kab ntawm cov menyuam, uas feem ntau dais radial load, tab sis kuj tuaj yeem dais axial load rau txhua qhov kev taw qhia.Nrog siab radial load peev xwm, nws yog tshwj xeeb tshaj yog haum rau ua hauj lwm nyob rau hauv hnyav load los yog kev co load, tab sis nws tsis tuaj yeem dais ntshiab axial load.Lub nplhaib sab nrauv ntawm cov kabmob no yog kheej kheej, yog li nws txoj kev sib dhos ua haujlwm zoo, thiab nws tuaj yeem them nyiaj rau qhov yuam kev concentricity.

Kev hnav tsis tu ncua yuav ua rau kev puas tsuaj zuj zus ntawm lub tshuab bearing, thiab thaum kawg ua rau poob ntawm cov kabmob qhov tseeb thiab lwm yam teeb meem cuam tshuam.Tapered roller bearings yog cais bearings.Ob qho tib si sab hauv thiab sab nraud ntawm cov kabmob muaj tapered raceways.Hom kabmob no tau muab faib ua ib-kab, ob-kab thiab plaub-kab tapered menyuam bearings raws li tus naj npawb ntawm kab ntsia.Hnav tuaj yeem cuam tshuam cov kev hloov pauv, qhov nce ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov kev hloov pauv ntawm lub npe nominal ntawm kev ua haujlwm, tuaj yeem cuam tshuam rau cov roj nplua nyeem lossis ua rau nws paug rau qee theem, ua rau lub lubrication muaj nuj nqi kom ploj tag, kom cov kabmob. poob qhov tseeb ntawm kev sib hloov thiab txawm tias tsis tuaj yeem khiav txawv txav.Hnav nyhuv yog ib qho ntawm cov qauv siv tau zoo ntawm ntau yam bearings.Raws li qhov teeb meem hnav, feem ntau nws tuaj yeem muab faib ua feem ntau siv abrasive thiab nplaum hnav.
