Tam sim no, slewing nplhaib yog dav siv nyob rau hauv ntau lub teb.Tab sis ntau tus neeg tsis paub yuav ua li cas xaiv qhov loj ntawm slewing nplhaib.Raws li tus kws tshaj lijslewing bearingmanufacturers, peb,XZWD Slewing Bearing Co., Ltd, hnub no yuav qhia nyob rau hauv kom meej yuav ua li cas xam tawm lubslewing bearingqhov ntau thiab tsawg.
1.Cov kabmob muaj peev xwm nkhaus ntawm cov kabmob slewing
Txhua homslewing bearingntawm cov khoom kuaj muaj qhov sib thooj load-nqa peev xwm nkhaus, thiab daim duab tuaj yeem pab tus neeg siv xaiv covslewing bearingua ntej.
Muaj ob hom kev nkhaus, ib qho yog qhov nkhaus zoo li qub (①line), qhov siab tshaj plaws loadslewing bearingtuaj yeem dais thaum nws ua kom zoo li qub.Lwm qhov yog bolt load txwv nkhaus (8.8, 10.9, 12.9), nws yog txiav txim siab thaum lub ntsia liaj qhov rooj qhov ntev fixture yog 5 lub sij hawm raws li lub bolt lub nominal txoj kab uas hla, thiab lub preload yog 70% ntawm cov khoom siv bolt lub yield txwv.
- 2.Kev suav txheej txheem ntawm slewing bearing xaiv
1) Cov txheej txheem xaiv
Xyuas kom tseeb tias qhov siab tshaj plaws loadslewing bearingtuaj yeem txhawb nqa thaum nws tseem zoo li qub (axial load Fa, radial load Fr, overturning moment M).Teem lub siab tshaj plaws load raws li tus nqi zoo li qub.Tus nqi zoo li qub yuav tsum xav txog qhov muaj peev xwm siab tshaj plaws ntawm lub hauv paus ntsiab lus, uas yuav tsum xaus qhov kev thauj khoom ntxiv thiab kev sim load.
Xyuas kom tseeb tias qhov zoo li qub kev ruaj ntseg coefficient fs raws li hom lub cav tseem ceeb (qhov teeb meem ntawm daim ntawv thov), uas nws tus lej muaj nqis saib cov lus 1.
Ua ntej xaiv homslewing bearing, kom paub tseeb tias txoj kev suav ntawm cov ntaub ntawv zoo li qub load Fa thiab M.
Xam Fa thiab M
Static load txwv nkhaus sib raug rau hom xaiv ntawmslewing bearingntawm cov qauv, thiab kos tawm (Faˊ, M ˊ)
Xyuas seb qhov chaw sib koom tes (Faˊ, M ˊ) puas nyob rau hauv qhov kev txwv tsis pub thauj khoom zoo li qub
Tshawb xyuas kev suav ntawm lub bolt lub peev xwm (saib ntu 5.2.4)
2) hom xaiv hauv static
Kev suav cov txheej txheem ntawm static siv load Fa 'thiab M'
Txoj kev I(a=60°)
Kev xaiv xam ntawm ib leeg-kab plaub taw tes tiv thaiv pobslewing bearingtxheej txheem los ntawm kev txhawb nqa lub kaum sab xis 45 ° thiab 60 ° feem.
Txoj Kev I (a = 60 °)
Fa′ = (Fa + 5.046 × Fr) × fs
M = M × fs
Method II(a=45°)
Fa′ = (1.225 × Fa + 2.676 × Fr) × fs
Luas = 1.225 x M x fs
Hauv cov qauv: Fa '-slewing bearingQhov sib npaug ntawm qhov chaw axial quab yuam (104 N)
M'-slewing bearingsib npaug overturning moment (N. m)
fs-kev nyab xeeb zoo hauv kev ua haujlwm zoo li qub ntawm kev txhawb nqa slewing (saib cov lus 1)
Tom qab ntawd pom ob lub ntsiab lus saum toj no ntawm qhov nkhaus, ib qho ntawm lawv nyob hauv qab ntawm qhov nkhaus.
Fa′ = (Fa + 2.05 × Fr) × fs
M′ = M × fs
Kev xaiv suav ntawm ob kab sib txawv ntawm lub pobslewing bearing, thaum Fr <= 10% Fa, qhov kev hloov ntawm lub kaum sab xis siab hauv txoj kev sib tw yuav tsum suav nrog, thov hu rau peb txog nws qhov kev suav.
Fa′ = Fa × fs
M = M × fs
Thaum xaiv cov menyuam kab tripleslewing bearing, tsuas yog xam qhov cuam tshuam ntawm axial raceway load thiab overturning lub caij.
Fa′ = Fa × fs
M = M × fs
2) Dynamic xaiv
Thov hu rau peb lub tuam txhab kev lag luam rau daim ntawv thov kev ua haujlwm tsis tu ncua, kev sib hloov ceev thiab lwm yam kev siv rau kev pab cuam lub neej ntawm kev txhawb nqa rotary.
3) Tshawb xyuas kev suav ntawm lub bolt tus kabmob muaj peev xwm
Qhov siab tshaj plaws load (tsis muaj kev ruaj ntseg zoo li qub fs) yog siv los thauj cov kev txhawb nqa teb.Xyuas seb lub load puas qis dua qhov txwv load nkhaus ntawm qib bolts xav tau;
Yog hais tias lub bolt bearing muaj peev xwm tsis txaus, peb tuaj yeem xaivslewing bearingdua lossis hu rau peb lub tuam txhab thev naus laus zis.
Lub Hoobkas tuaj yeem muab cov ntaub ntawv raws li cov qauv khoom, siv cov kabmob muaj peev xwm zoo li qub, raws li cov kabmob teb hom kev xaiv kev suav cov txheej txheem ntawm kev xaiv ua ntej.slewing bearing, thiab tshuab nrog kuv lub tuam txhab kom paub meej.Kuj tseem tuaj yeem muab cov ntaub ntawv ntawm cov kabmob teb rau peb lub tuam txhab, thaum nqa ntawm kev xaiv tsim los ntawm kuv lub tuam txhab, thov nug rau 《 teb cov kabmob xaiv cov tshuab tsis siv lub rooj 》 (xws li cov ntawv txuas A thiab cov ntawv txuas ntxiv B hauv cov lus parameter), thiab sau nyob rau hauv, yog li ntawd peb yuav xa tuaj rau koj sai li sai tau raws li qhov tseeb teb bearing xaiv txoj kev npaj ntawm kev lag luam thiab cov tswv yim.
