Txawv dov bearings muaj cov yam ntxwv sib txawv thiab haum rau ntau yam kev thov ntawm ntau yam khoom siv tshuab. Cov neeg ua haujlwm xaiv yuav tsum xaiv tus qauv tsim nyog ntawm cov kabmob sib txawv thiab ntau hom kabmob.

1. Xaiv cov qauv bearing raws li cheeb tsam thiab txoj hauj lwm ntawm cov cuab yeej siv tshuab ua haujlwm los ntawm cov kabmob:

Peb feem ntau siv pobbearingsrau me shafts, thiab cov menyuam bearings rau loj shafts. Yog tias txoj kab uas hla ntawm cov kabmob muaj tsawg, peb feem ntau siv rab koob rau cov menyuam bearings, ultra-lub teeb pob bearings lossis cov menyuam bearings; thaum lub bearing yog txwv nyob rau hauv lub axial ib feem ntawm cov khoom, nqaim los yog ultra-qaub series ntawm pob bearings los yog cov menyuam bearings.

2. Xaiv cov qauv bearing raws li cov load. Lub load yuav tsum yog qhov tseem ceeb tshaj plaws uas yuav tsum tau txiav txim siab thaum xaiv bearings:

Cov menyuam bearings tuaj yeem tiv taus qhov hnyav, thaum lub pob bearings kuj me me. Cov kabmob ua los ntawm cov hlau carburized tuaj yeem tiv taus kev poob siab thiab kev vibration loads. Thaum cov loads radial nkaus xwb, peb tuaj yeem xaiv thrust pob bearings, cylindrical roller bearings lossis koob rau cov menyuam bearings. Thaum lub axial load me me, peb tuaj yeem xaiv lub pob thrust pob; Thaum lub axial load kuj loj, ib tug thrust roller bearing feem ntau yog siv. Thaum cov kabmob bears ob qho tib si axial thiab radial loads, peb feem ntau siv angular contact pob bearings lossis tapered roller bearings.

3. Raws li tus kheej-aligning yam ntxwv ntawm cov kabmob, xaiv cov kabmob qauv:

Thaum lub axis ntawm tus ncej tsis zoo ib yam li lub axis ntawm lub rooj zaum bearing, los yog nws yog ib qho yooj yim yuav tsum tau khoov los yog skewed nyob rau hauv lub siab, lub self-aligning pob los yog tus kheej-aligning roller bearing nrog zoo heev self-aligning muaj nuj nqi, thiab nws sab nrauv pob bearing tuaj yeem xaiv. Hom kabmob no tuaj yeem ua kom muaj kev ua haujlwm zoo thaum lub ncej me ntsis skewed lossis khoov. Qhov zoo thiab qhov tsis zoo ntawm cov kabmob qhov kev ua haujlwm ntawm tus kheej yog cuam tshuam nrog nws qhov ua tau tsis yog-axiality. Qhov loj dua tus nqi, qhov zoo dua qhov kev ua tau zoo ntawm tus kheej.

4. Raws li qhov nruj ntawm cov kabmob, xaiv cov kabmob qauv:

Lub elastic deformation ntawm dovbearingstsis loj thiab tuaj yeem tsis quav ntsej hauv cov cuab yeej siv tshuab feem ntau, tab sis hauv qee cov cuab yeej siv tshuab, xws li cov cuab yeej siv tshuab spindles, bearing stiffness yog qhov tseem ceeb.
Peb feem ntau siv cylindrical cov menyuam bearings los yog tapered menyuam bearings rau tshuab cuab tam spindle bearings. Vim hais tias ob hom bearings no yog tus taw tes tiv tauj thaum nyob rau hauv load, lub rigidity tsis muaj zog.
Tsis tas li ntawd, ntau yam bearings tseem tuaj yeem siv preload los ua kom cov kabmob nruj. Xws li angular hu rau pob bearings thiab tapered cov menyuam bearings, txhawm rau txhim kho kev txhawb nqa rigidity, qee qhov axial quab yuam feem ntau yog ntxiv ua ntej thaum sib dhos ua rau lawv sib dhos. Nws yog tshwj xeeb tshaj yog nyob rau ntawm no: lub preload quab yuam tsis tuaj yeem loj dhau. Txwv tsis pub, kev sib txhuam ntawm cov kabmob yuav nce, qhov kub thiab txias yuav nce, thiab kev pabcuam lub neej ntawm cov kabmob yuav raug kev puas tsuaj.

5. Raws li cov kabmob ceev, xaiv cov kabmob qauv:

Feem ntau hais lus, angular contact bearings thiab cylindrical roller bearings yog tsim rau siv nyob rau hauv high-ceev chaw ua hauj lwm; tapered roller bearings tuaj yeem siv rau hauv qhov chaw ua haujlwm qis. Thrust pob bearings muaj qhov txwv tsis pub ceev thiab tsuas yog haum rau cov chaw uas muaj qhov qis dua.

Rau tib hom kabmob, qhov me dua qhov tshwj xeeb, qhov siab dua qhov tso cai sib hloov ceev. Thaum xaiv tus qauv bearing, xyuam xim rau qhov tseeb ceev tsawg tshaj li qhov txwv ceev.
