Zoo ib yam li cov pob bearings, cov menyuam bearings muaj kab sib txuas es tsis yog qhov taw tes, ua rau lawv muaj peev xwm ntau dua thiab muaj zog dua.Rollers lawv tus kheej tuaj nyob rau hauv ntau yam duab, xws li, cylindrical, kheej kheej, tapered, thiab koob.Cylindrical roller bearings tswj tsuas yog txwv thrust loads.Spherical roller bearings tuaj yeem ua raws li qhov tsis sib xws thiab kev sib tw ntau dua, thiab, thaum muab ob npaug rau, thawb rau hauv ob qho tib si.Tapered roller bearings tuaj yeem tswj xyuas qhov hnyav hnyav.Koob bearings, ib tug txawv ntawm cylindrical cov menyuam bearings, muaj peev xwm lis siab radial loads rau lawv loj, thiab yuav ua tau raws li koob rau cov menyuam thrust bearings.

Cov menyuam bearings yog muaj raws li tag nrho-complement designs thiab koob bearings yuav luag invariably yuav ntawm no style.Koob bearings yog tshwj xeeb tshaj yog zoo nrog reciprocating motions, tab sis kev sib txhuam yuav siab dua vim rau cov menyuam-tawm-cov menyuam rubbing.

Thaum siv cylindrical roller bearings ntawm shafts nrog angular misalignment, nws yog qhov zoo dua los siv ob lub luv luv cov menyuam bearings rov qab-rau-rov qab es tsis yog ib tus menyuam cov kabmob ntev.

Xaiv lub Pob lossis Cov Menyuam Bearing
Raws li txoj cai dav dav, pob bearings yog siv ntawm qhov nrawm dua thiab sib zog dua li cov menyuam bearings.Cov menyuam bearings ua tau zoo dua nyob rau hauv kev poob siab thiab cuam tshuam kev thauj khoom.

Pob bearings feem ntau yog muag raws li cov rooj sib txoos thiab tsuas yog hloov raws li units.Cov menyuam kabmob feem ntau tuaj yeem raug tshem tawm thiab cov neeg nqa khoom thiab cov menyuam yaus, lossis cov kev sib tw sab nrauv lossis sab hauv, hloov ib tus zuj zus.Tsheb-log-tsav tsheb siv xws li kev npaj rau pem hauv ntej log.Qhov zoo ntawm qhov kev tsim no yog tias cov kev sib tw tuaj yeem ua kom haum rau cov shafts thiab nyob rau hauv vaj tse los tsim cov rooj sib txoos mus tas li yam tsis muaj kev pheej hmoo rau kev puas tsuaj rau cov yob lawv tus kheej.

Ib kab kab bearings yog standardized thiab siv tau interchangeably ntawm manufacturers.Cov menyuam bearings yog tsawg-formally standardized yog li tus specifier yuav tsum tau sab laj nrog ib tug neeg tsim khoom catalog los xaiv ib tug tsim nyog rau daim ntawv thov.

Rolling-element bearings yog tsim los nrog qee tus nqi ntawm kev tshem tawm sab hauv.Txhua qhov kev tsis sib haum xeeb uas tsuas yog rub lub pob tawm ntawm txoj haujlwm thiab tshem tawm qhov kev tshem tawm sab hauv no yuav tsum tsis txhob cuam tshuam ntau rau lub neej ntawm cov kabmob.Cov menyuam bearings yog rhiab heev rau angular misalignment.Piv txwv li, lub pob bearing khiav ntawm nruab nrab ceev nrog ib tug haum xoob haum yuav ua tau zoo nrog angular misalignment siab li 0.002 rau 0.004 in./in.nruab nrab ntawm cov kabmob thiab ncej.Ib tug cylindrical roller bearing, piv txwv li, tej zaum yuav muaj teeb meem yog misalignment tshaj 0.001 in./in.Cov neeg tsim khoom feem ntau yuav muab qhov kev lees paub ntawm angular misalignment rau lawv tus kheej bearings.
