Cov qauv ntawm angular contact pob bearings
Kev tsim cov Angular Sib cuag Pob Bearings Angular hu rau pob bearings yog tsim muaj plaub qhov loj, nrog rau kev tsim cov yam ntxwv uas ua kom muaj kev sib tw ntawm kev sib hloov ceev. Inner thiab Outer Rings ntawm Cov Kabmob: Cov kev sib tw ntawm cov kabmob ' puab thiab sab nraud yog tsim los nrog cov txheej txheem nkhaus curvature radii kom, ntawm ib sab, \\ lub xub pwg nyom siab dua, thiab nyob rau sab saum toj ntawm lub xub pwg qis dua - qhov no ua rau kev sib dhos ntau dua ntawm cov khoom thiab, yog li ntawd, muaj peev xwm ntau dua. Feem ntau, sab hauv thiab sab nraud ntawm cov kabmob tsis yog - sib cais. Rolling Elements and Cage: The Balls: Yog dov cov ntsiab lus uas tau teem rau hauv ib lub tawb. Lub Cage: Tuav cov npas xws li lawv qhov sib npaug sib npaug, coj lawv txoj kev sib hloov kom raug, thiab zam kev sib tsoo. Nyob ntawm seb hom kabmob thiab cov xwm txheej ntawm daim ntawv thov, cov khoom siv tawb xws li stamped steel, tig (machined) tooj dag, lossis qee cov chav kawm ntawm engineering plastics (xws li, nylon) yog siv. Hu rau lub kaum sab xis ( ): Ntawm ntau cov ntsiab lus geometric (tsis suav) ntawm cov kabmob, qhov tseem ceeb tshaj plaws yog lub kaum sab xis ntawm kev sib cuag, uas txhais tau tias yog lub kaum sab xis uas tsim los ntawm qhov qub ntawm qhov chaw ntawm kev sib cuag ntawm cov khoom sib tw nrog lub raceway thiab lub dav hlau radial ntawm cov kabmob.
Feem ntau siv cov ces kaum sib cuag yog:
15 degree: Rau siab tshaj tawm, lub teeb load, siab precision daim ntawv thov.
25℃(A / AC hom): Rau lub hom phiaj dav dav, thiab ua haujlwm kom ua tiav qhov sib npaug ntawm qhov nrawm thiab lub peev xwm thauj khoom.
30℃(Ib hom): Pom nyob rau hauv ob peb tus qauv.
40℃(B hom): Tsim nyog rau hnyav-lub luag haujlwm, siab axial load qhov xwm txheej.
Feem ntau, qhov loj dua lub kaum sab xis ntawm kev sib cuag, lub peev xwm ntau dua rau kev thauj khoom axial, tab sis qhov no feem ntau ua rau qis tshaj qhov nrawm. Cov ntsaws ruaj ruaj thiab plua plav tiv thaiv (xaiv tau): Kev saib xyuas- kev ua haujlwm pub dawb yog ua tau nrog qee qhov ob npaug - kab angular hu rau pob bearings vim tias lub npog plua plav lossis lub foob tau haum thiab cov kabmob yog sab hauv ua ntej -greased.
Cov lus nug nquag nug txog Angular Sib cuag Pob Bearings
Q1: Vim li cas ib leeg - kab angular hu rau pob bearings feem ntau ua khub? Ib leeg - kab angular hu rau pob bearings tuaj yeem ua raws li cov khoom thauj axial hauv ib qho kev taw qhia. Nrog radial loads, ib qho ntxiv axial load yog siv uas ua rau qee qhov axial txav ntawm sab hauv thiab sab nraud. Yog li kev sib xyaw ntawm ob lub bearings tau hais kom sib npaug qhov ntxiv axial load thiab ua kom cov kabmob sib xyaw kom haum rau axial loads nyob rau hauv qhov sib txawv.
Q2: Kuv yuav tsum xav txog dab tsi rau kev xaiv rov qab - mus rau - rov qab (DB) thiab ntsej muag - rau - ntsej muag (DF) kev npaj? Nrog DB (rov qab-rau-rov qab) kev npaj, cov kab ntawm kev txiav txim rau ob lub bearings yog txhais tau tias yuav sib txawv sab nraud, ua rau kom-hu ua "txhawb puag" uas nyob rau hauv lem txhim kho lub sij hawm tsis kam thiab lub rigidity ntawm lub bearing assembly.Qhov no yog tsim nyog rau cantilever siv los yog rooj plaub nrog lub sij hawm loads (xws li nyob rau hauv pem hauv ntej ntawm ib tug spindle). DF (lub ntsej muag-rau-lub ntsej muag) kev teeb tsa txhais tau hais tias tsis tshua muaj zog, tab sis muaj peev xwm ua kom haum rau thermal expansion thiab installation yuam kev hauv cov ncej.
Q3: Dab tsi yog hybrid ceramic pob bearing txhais tau tias, thiab nws muaj txiaj ntsig dab tsi? Nyob rau hauv ib tug hybrid ceramic pob bearing, cov ntsiab lus dov yog ua los ntawm cov khoom siv ceramic uas yog Silicon Nitride (Si₃N₄), thaum lub nplhaib sab hauv thiab sab nrauv tseem yog hlau. Cov txiaj ntsig ntawm hybrid pob bearings muaj xws li: cov pob zeb ceramic yog sib dua (txog 40% qhov hnyav ntawm cov hlau), uas txhais tau hais tias nyob rau hauv high speeds lawv tsim tsawg centrifugal quab yuam, yog li tsawg plam thiab tsawg tshav kub kev sib txhuam, thiab cov ceramic khoom yog ntau nyuaj, uas txhais tau hais tias nws yog ntau hnav resistant, ncua lub neej ntawm cov kabmob.
Q4: Puas yog nws zoo dua kom muaj preload ntau dua? Tsis yog. Ntau dhau preload tuaj yeem ua rau muaj kev sib txhuam mus rau qhov chaw uas nws ua kom muaj cua sov ntau dhau, uas tuaj yeem rhuav tshem cov roj nplua nyeem, thiab tuaj yeem ua rau cov kabmob ua ntej nws lub neej xav tau. Ib qho zoo preload yog nyob rau saum toj ntawm kev ua haujlwm rau kev sib npaug zoo nrog kev nruj thiab qhov tseeb thiab lub neej ntawm cov bearings.
Q5: Yuav ua li cas ib tug paub thaum lub angular contact pob bearing xav tau relubrication? Rau cov bearings uas muaj roj txiv mis, lubricating lawv yuav tsum tau ua nyob rau hauv ib ntus, sib txawv nrog lub sij hawm ua hauj lwm, kub thiab tej yam kev mob. Muab kaw los yog txij nkawm dawb bearings: tsis txhob relubricate lawv. Nyob rau hauv lub kub kub, kev kub ceev, los yog hnyav load tej yam kev mob, lub lubrication lub sij hawm yuav tsum luv luv, thiab compatibility ntawm tshiab thiab qub roj yuav tsum tau guaranteed.
