Thaum xaiv cov kabmob, koj yuav tsum xav txog ntau yam tseem ceeb.Thawj yam uas yuav tsum tau xav txog yog qhov load uas cov kabmob tuaj yeem nqa tau.Muaj ob hom kev thauj khoom.
-Axial load: parallel mus rau axis ntawm kev sib hloov
-Radial load: perpendicular mus rau axis ntawm kev sib hloov
Txhua hom kabmob tshwj xeeb yog tsim los txhawb nqa axial lossis radial loads.Qee cov bearings tuaj yeem nqa ob hom kev thauj khoom: peb hu lawv ua ke cov khoom thauj.Piv txwv li, yog tias koj cov kabmob yuav tsum nqa cov khoom sib xyaw ua ke, peb xav kom koj xaiv cov kabmob tapered rau cov menyuam.Yog tias koj xav tau cov kabmob uas tuaj yeem tiv taus siab radial loads, peb pom zoo kom cov menyuam kabmob cylindrical.Ntawm qhov tod tes, yog tias koj cov kabmob xav tau los txhawb nqa lub nra hnyav, lub pob bearing yuav txaus, vim tias cov kabmob no feem ntau pheej yig dua.
Kev sib hloov ceev yog lwm qhov yuav tsum tau xav txog.Qee cov kabmob tuaj yeem tiv taus qhov nrawm dua.Yog li, cylindrical roller bearings thiab koob rau cov menyuam bearings nrog tawb muaj qhov sib hloov ceev dua piv rau cov kabmob uas tsis muaj tawb.Txawm li cas los xij, qee zaum kev nrawm dua tuaj ntawm tus nqi ntawm kev thauj khoom.
Koj kuj yuav tsum xav txog qhov sib txawv ntawm qhov ua tau;qee cov bearings tsis haum rau qhov no, piv txwv li ob-kab pob bearings.Yog li ntawd, kev saib xyuas yuav tsum tau them rau kev tsim kho ntawm cov kabmob: cov kabmob recessed thiab cov kabmob kheej kheej yog qhov ua rau qee qhov tsis zoo.Peb pom zoo kom koj siv tus kheej-aligning bearings los kho, thiaj li yuav tau kho qhov tsis xws luag los ntawm ncej dabtsi yog khoov los yog mounting yuam kev.
Ntxiv dua thiab, cov kev ua haujlwm tseem ceeb heev thaum xaiv cov kabmob zoo tagnrho.Yog li ntawd, nws yog ib qho tsim nyog los txheeb xyuas qhov chaw ua haujlwm uas cov kabmob yuav ua haujlwm.Koj cov bearings yuav raug ntau yam kab mob.Qee daim ntawv thov tuaj yeem ua rau muaj suab nrov, kev cuam tshuam thiab / lossis kev vibrations.Yog li ntawd, koj cov bearings yuav tsum muaj peev xwm tiv tau cov shocks ntawm ib sab thiab tsis ua rau inconvenience ntawm lwm yam.
Lwm qhov tseem ceeb uas yuav tau xav txog yog kev coj lub neej.Ntau yam, xws li kev siv ceev lossis rov siv dua, tuaj yeem cuam tshuam rau lub neej ntev.
Xaiv lub kaw lus sealing yog qhov tseem ceeb los xyuas kom meej tias koj cov bearings ua haujlwm kom raug thiab ntev ntev;Yog li ntawd, nws yog ib qho tseem ceeb los xyuas kom meej tias cov bearings yeej ib txwm zoo tiv thaiv los ntawm tej impurities thiab lwm yam xws li plua plav, dej, corrosive kua los yog txawm siv lubricants.Qhov kev xaiv no nyob ntawm seb hom roj nplua nyeem, qhov chaw ib puag ncig (thiab yog li ntawd kuj nyob ntawm hom kev sib kis), cov kua dej siab thiab ceev.
Txhawm rau muab qhov pib zoo rau koj, cov kua dej siab yog qhov kev txiav txim siab hauv kev xaiv cov txheej txheem sealing.Yog tias qhov siab txaus (piv txwv li hauv thaj tsam ntawm 2-3 bar), lub tshuab foob yog qhov zoo tagnrho.Txwv tsis pub, qhov kev xaiv yuav raug cuam tshuam ncaj qha rau hom roj nplua nyeem, roj lossis roj.Piv txwv li, rau roj lubrication, feem ntau cov kev daws teeb meem yog: deflectors los yog gaskets, machined los yog nqaim raws nrog grooves;nyob rau hauv cov ntaub ntawv ntawm cov roj lubrication, lub sealing system yog feem ntau
nrog rau cov grooves rau roj rov qab.
Cov xwm txheej ntawm kev siv kuj tseem cuam tshuam rau koj xaiv, tshwj xeeb tshaj yog thaum sib dhos bearings.Kev txiav txim siab yuav tsum tau muab rau qhov rigidity thiab precision yuav tsum tau thaum lub bearing yog siv.Qee zaum, lub preload tuaj yeem siv rau cov kabmob sib dhos kom nws qhov nruj.Tsis tas li ntawd, lub preload yuav muaj txiaj ntsig zoo rau kev coj tus kheej lub neej thiab cov suab nrov hauv lub cev.Thov nco ntsoov tias yog tias koj xaiv preload (radial lossis axial), koj yuav tsum paub qhov nruj ntawm txhua qhov chaw los ntawm software lossis kev sim.
Ntawm koj cov kev xaiv, koj yuav tsum coj mus rau hauv tus account cov khoom zoo tagnrho rau cov kabmob.Cov kabmob tuaj yeem ua los ntawm cov hlau, yas lossis ceramic.Cov khoom siv bearing nyob ntawm nws qhov kev siv.Peb pom zoo kom koj xaiv cov kabmob uas tiv taus compression tshaj plaws.Txawm li cas los xij, cov khoom siv yuav cuam tshuam tus nqi ntawm cov kabmob.
