Koob roller bearings yog cylindrical roller bearings.Cov txheeb ze ntawm lawv txoj kab uas hla, cov yob yog nyias thiab ntev.Cov menyuam no hu ua needle roller.Txawm hais tias nws muaj qhov me me hla, cov kabmob tseem muaj lub peev xwm thauj khoom siab, yog li nws yog qhov tshwj xeeb tshaj yog haum rau lub sijhawm uas muaj qhov txwv radial.

Lub contour nto ntawm rab koob rau cov menyuam tau cog lus me ntsis ntawm qhov kawg ntawm qhov kawg.Koob thiab taug qab kab kev kho qhov tshwm sim tuaj yeem zam kev puas tsuaj ntawm ntug kev nyuaj siab.Ntxiv nrog rau cov ntawv teev npe, cov kabmob uas tuaj yeem siv rau kev tsim vaj tsev dav dav, xws li: qhib rub rab koob rau cov menyuam bearings (1), kaw rab koob rau cov menyuam bearings (2), koob rau cov menyuam bearings nrog lub nplhaib puab (3) thiab tsis tas li. lub nplhaib puab koob rau cov menyuam bearings (4), SKF tuaj yeem muab ntau hom koob rau cov menyuam bearings, xws li: 1, koob rau cov menyuam tawb sib dhos 2, koob rau cov menyuam bearings tsis muaj tav 3, tus kheej-aligning koob rau cov menyuam bearings 4, kev sib txuas ntawm rab koob / pob bearings 5, sib xyaw koob / thrust pob bearings 6, sib xyaw koob / cylindrical roller thrust bearings.

Drawn khob koob rau cov menyuam bearings

Drawn khob koob rau cov menyuam bearings yog koob bearings nrog ib tug nyias stamped txheej nplhaib.Nws lub ntsiab feature yog nws qhov siab seem siab thiab siab load peev xwm.Nws yog tsuas yog siv rau bearing configuration nrog compact qauv, pheej yig tus nqi, thiab lub puab lub qhov ntawm lub bearing box yuav siv tsis tau raws li lub raceway ntawm lub koob tawb los ua ke.Cov bearings thiab bearings vaj tse yuav tsum tau ntsia rau hauv ib qho kev cuam tshuam haum.Yog hais tias axial positioning functions xws li lub xub pwg nyom thiab tuav rings yuav raug tshem tawm, ces lub bore nyob rau hauv lub thawv bearing yuav ua tau heev yooj yim thiab yig.

Drawn khob koob rau cov menyuam bearings mounted rau ntawm ncej kawg yog qhib rau ob sab (1) thiab kaw rau ib sab (2).Lub hauv paus kawg lub ntsej muag ntawm kaw lub nplhaib sab nrauv tuaj yeem tiv taus me me axial guiding rog.

Drawn khob koob rau cov menyuam bearings feem ntau tsis muaj lub nplhaib puab.Qhov twg cov ntawv xov xwm tsis tuaj yeem ua kom tawv thiab hauv av, lub nplhaib sab hauv uas teev nyob rau hauv lub rooj yuav siv tau.Lub hardened steel txheej nplhaib ntawm lub khob khob koob rau cov menyuam bearing yog inseparable los ntawm rab koob rau cov menyuam tawb los ua ke.Qhov chaw pub dawb rau lubricant cia tuaj yeem txuas ntxiv lub sijhawm relubrication.Cov bearings feem ntau yog tsim nyob rau hauv ib kab.Tsuas yog rau cov kab dav dav ntawm cov kabmob 1522, 1622, 2030, 2538 thiab 3038, lawv tau nruab nrog ob rab koob rau lub tawb sib dhos.Lub nplhaib sab nraud muaj lub qhov roj nplua nyeem.Raws li cov neeg siv xav tau, tag nrho ib-kab kos koob rau cov menyuam bearings nrog lub taub hau loj dua lossis sib npaug li 7 hli tuaj yeem nruab nrog cov nplhaib sab nrauv (code suffix AS1) nrog lub qhov lubrication.

Kos khob koob rau cov menyuam bearings nrog roj foob

Qhov twg cov roj ntsaws ruaj ruaj tsis tuaj yeem ntsia tau vim qhov chaw txwv, rab koob rau cov menyuam bearings (3 txog 5) nrog cov roj foob stamped lub nplhaib sab nraud tuaj yeem muab qhib lossis kaw xaus.Hom kabmob no yog nruab nrog kev sib txhuam roj foob ntawm polyurethane lossis hluavtaws roj hmab, uas muaj cov roj lithium-based roj nrog kev ua haujlwm zoo los tiv thaiv xeb, haum rau kev ua haujlwm kub -20 txog + 100 ° C.

Lub nplhaib puab ntawm cov roj ntim cov kabmob yog 1 hli dav dua lub nplhaib sab nraud.Qhov no tso cai rau cov kabmob kom ntseeg tau tias cov roj foob ua haujlwm zoo thaum lub ncej muaj qhov hloov pauv me me ntawm cov kabmob, kom cov kabmob tsis muaj kuab lom.Cov kabmob puab lub nplhaib kuj muaj qhov lubrication qhov, uas tuaj yeem rov ua dua los ntawm lub nplhaib sab nraud lossis lub nplhaib sab hauv raws li qhov xav tau ntawm cov kabmob configuration.
