Angular contact bearings, ib hom pob bearing nyob rau hauv dov bearings, yog tsim los ntawm ib lub nplhaib sab nrauv, puab nplhaib, steel pob, thiab lub tawb. Ob qho tib si sab hauv thiab sab nrauv muaj cov kab sib tw uas tso cai rau kev sib txheeb axial hloov chaw. Cov kabmob no tshwj xeeb tshaj yog haum rau kev tuav cov khoom sib xyaw ua ke, txhais tau tias lawv tuaj yeem haum rau ob qho tib si radial thiab axial rog. Ib qho tseem ceeb tshaj plaws yog lub kaum sab xis ntawm kev sib cuag, uas yog hais txog lub kaum sab xis ntawm txoj kab sib txuas ntawm lub pob ntawm cov ntsiab lus sib cuag ntawm txoj kev sib tw hauv lub dav hlau radial thiab kab perpendicular rau cov kabmob axis. Lub kaum sab xis loj dua tuaj yeem ua rau cov kabmob muaj peev xwm los tuav axial loads. Hauv cov kabmob zoo, 15 ° kev sib cuag lub kaum sab xis feem ntau yog siv los muab cov peev txheej axial txaus thaum tswj kev sib hloov ceev.
Ib kab angular hu rau bearingstuaj yeem txhawb nqa radial, axial, lossis composite loads, tab sis ib qho axial load yuav tsum tau siv rau hauv ib qho kev taw qhia xwb. Thaum siv radial loads, ntxiv axial rog yog tsim, uas yuav tsum tau ib tug coj rov qab load. Vim li no, cov kabmob no feem ntau yog siv ua khub.
Ob-kab angular contact bearingstuaj yeem tswj tau ntau yam radial thiab bidirectional axial ua ke loads, nrog radial loads yog qhov tseem ceeb tshaj plaws, thiab lawv tuaj yeem txhawb nqa radial nkaus xwb. Tsis tas li ntawd, lawv tuaj yeem txwv axial hloov chaw nyob rau hauv ob qho tib si kev taw qhia ntawm lub ncej lossis vaj tsev.
Kev txhim kho angular hu rau pob bearings yog qhov nyuaj tshaj li qhov sib sib zog nqus groove pob bearings thiab feem ntau yuav tsum tau ua ke nrog kev teeb tsa ua ntej. Yog tias tsim nyog, qhov tseeb thiab kev pabcuam lub neej ntawm cov cuab yeej tuaj yeem txhim kho tau zoo. Txwv tsis pub, nws tsis tsuas yog ua tsis tau raws li qhov yuav tsum tau ua, tab sis cov kabmob lub neej ntev kuj yuav raug cuam tshuam.
Muaj peb homangular contact pob bearings: rov qab-rau-rov qab, ntsej muag-tawm thiab tandem kev npaj.
1. Rov qab-rau-Rov qab - lub ntsej muag dav ntawm ob lub bearings yog qhov sib txawv, lub kaum sab xis ntawm cov kabmob kis tau raws li cov kev taw qhia ntawm axis ntawm kev sib hloov, uas tuaj yeem ua rau kom muaj zog ntawm nws cov radial thiab axial txhawb cov ces kaum, thiab qhov siab tshaj plaws. anti-deformation muaj peev xwm;
2. Lub ntsej muag-rau-Face - lub ntsej muag nqaim ntawm ob lub bearings yog qhov sib txawv, lub kaum sab xis ntawm cov kabmob converges ntawm cov kev taw qhia ntawm lub axis ntawm kev sib hloov, thiab lub rigidity ntawm lub bearings yog me me. Vim tias lub nplhaib sab hauv ntawm cov kabmob nthuav tawm ntawm lub nplhaib sab nraud, thaum lub nplhaib sab nraud ntawm ob lub bearings raug nias ua ke, thawj qhov kev tshem tawm ntawm lub nplhaib sab nraud raug tshem tawm, thiab qhov preload ntawm cov kabmob tuaj yeem nce ntxiv;
3. Tandem Arrangement - lub ntsej muag dav ntawm ob lub bearings yog nyob rau hauv ib qho kev taw qhia, lub kaum sab xis ntawm lub bearings yog nyob rau hauv tib txoj kev thiab parallel, thiaj li hais tias ob bearings muaj peev xwm sib koom ua hauj lwm load nyob rau hauv tib txoj kev. Txawm li cas los xij, txhawm rau txhawm rau txhawm rau txhawm rau txhim kho axial ruaj khov, ob khub ntawm cov kabmob uas tau teem rau hauv cov koob yuav tsum tau muab tso rau sab nraud ntawm ob qho kawg ntawm lub ncej. Ib kab angular hu rau pob bearings nyob rau hauv tandem kev npaj yuav tsum yeej ib txwm raug kho tiv thaiv lwm bearing inversely teem rau ncej taw qhia nyob rau hauv lub opposite direction.
Zoo siab txais tossab lajntau bearing ntsig txog cov khoom thiab kev daws teeb meem. Txij xyoo 1999, peb tau muabtxhim khu kev qha bearing dawsrau tsheb manufacturers thiab Aftermarket. Cov kev pabcuam raug txiav ua kom zoo thiab ua haujlwm zoo.
