Txawm hais tias lub bearing ua hauj lwm clearance loj los yog me dua lub installation clearance nyob ntawm seb cov nyhuv ua ke ntawm ob yam.
Qee qhov dov bearings tsis tuaj yeem hloov kho rau kev tshem tawm, cia nyob ib leeg disassembled.Cov kabmob no muaj rau hom, uas yog hom 0000 rau hom 5000;qee qhov dov bearings tuaj yeem kho qhov kev tshem tawm, tab sis tsis tuaj yeem disassembled.1000 hom, 2000 hom thiab 3000 hom dov bearings, lub installation clearance ntawm cov hom dov bearings yuav tsawg dua qhov qub clearance tom qab hloov;Tsis tas li ntawd, qee qhov bearings tuaj yeem raug tshem tawm, thiab qhov kev tshem tawm tuaj yeem hloov kho, muaj 7000 hom (tapered roller bearings), 8000 hom (thrust pob bearing) thiab 9000 hom (thrust roller bearing), peb hom bearings no tsis muaj thawj clearance;6000 hom thiab 7000 hom dov bearings, lub radial clearance yog txo, lub axial clearance Nws kuj ua me, thiab vice versa, thaum rau hom 8000 thiab hom 9000 dov bearings, tsuas yog lub axial clearance muaj tswv yim tseem ceeb.
Tsim nyog installation clearance yog pab tau rau kev ua hauj lwm ib txwm ntawm dov bearings.Yog tias qhov kev tshem tawm tsawg dhau, qhov kub ntawm cov kabmob dov yuav nce, thiab nws yuav tsis ua haujlwm zoo, thiab txawm tias cov khoom dov yuav raug daig;Yog tias qhov kev tshem tawm loj dhau, cov khoom siv yuav vibrate heev, thiab cov kabmob dov yuav nrov.
Txoj kev tshuaj xyuas ntawm radial clearance yog raws li nram no:
1. Txoj kev xav
1. Muaj ib txhais tes los tig cov kabmob, thiab cov kabmob yuav tsum ruaj khov thiab hloov tau yam tsis muaj jamming.
2. Co lub nplhaib sab nraud ntawm cov kabmob los ntawm txhais tes, txawm tias qhov radial clearance tsuas yog 0.01mm, axial txav ntawm qhov taw tes saum toj kawg nkaus ntawm cov kabmob yog 0.10 ~ 0.15mm.Txoj kev no yog mob siab rau ib kab radial pob bearings.
2. Kev ntsuas ntsuas
1. Tshawb xyuas nrog lub ntsuas ntsuas kom paub meej tias qhov siab tshaj plaws ntawm qhov kev sib tw ntawm cov kabmob dov, ntxig lub ntsuas ntsuas ntawm qhov dov thiab lub nplhaib sab nraud ntawm 180 °, thiab lub thickness ntawm lub ntsuas qhov ntsuas nrog qhov tsim nyog elasticity yog radial. clearance ntawm bearing.Txoj kev no yog dav siv nyob rau hauv spherical bearings thiab cylindrical roller bearings.
2. Tshawb xyuas nrog lub dial gauge, ua ntej teem lub dial gauge rau xoom, thiab tom qab ntawd jack li lub nplhaib sab nraud ntawm cov kabmob dov.Kev nyeem ntawv ntawm dial gauge yog radial clearance ntawm cov kabmob.
Txoj kev tshuaj xyuas ntawm axial clearance yog raws li nram no:
1. Txoj kev xav
Siv koj tus ntiv tes los xyuas qhov axial clearance ntawm dov bearings.Txoj kev no yuav tsum tau siv thaum lub qhov kawg ntawm qhov kawg raug nthuav tawm.Thaum cov ncej kawg raug kaw lossis tsis tuaj yeem kuaj xyuas nrog cov ntiv tes rau lwm yam laj thawj, nws tuaj yeem kuaj xyuas seb lub ncej tig tau ywj pheej.
2. Kev ntsuas ntsuas
(1) Tshawb xyuas nrog lub ntsuas ntsuas ntsuas, txoj kev ua haujlwm yog tib yam li kev kuaj xyuas cov radial clearance nrog lub ntsuas ntsuas, tab sis qhov axial clearance yuav tsum yog.
c=λ/(2sinβ)
qhov twg c-axial clearance, mm;
λ—— thickness ntawm feeler gauge, mm;
β-Bearing kaum sab xis, (°).
(2) Tshawb xyuas nrog lub ntsuas ntsuas.Thaum tus ncej txav nrog lub crowbar ua rau lub ncej nyob rau hauv ob txoj hauj lwm huab, qhov sib txawv ntawm lub dial gauge nyeem ntawv yog qhov axial clearance ntawm cov kabmob.Txawm li cas los xij, lub zog siv rau lub crowbar yuav tsum tsis txhob loj dhau, txwv tsis pub lub casing yuav elastically deformed, thiab txawm tias qhov deformation me me, nws yuav cuam tshuam qhov tseeb ntawm qhov ntsuas axial clearance.
