Turntable bearings

Feem ntau siv teb workbench hauv CNC tshuab cuab yeej suav nrog indexing workbench thiab CNC teb workbench.

CNC rotary rooj yuav siv tau los ua kom tiav ib ncig noj mov. Ntxiv nrog rau kev paub txog lub voj voog pub mov, CNC tig lub rooj (hu ua CNC turntable) kuj tuaj yeem ua tiav qhov kev ntsuas ntsuas.

Lub rooj teb yog dav siv nyob rau hauv ntau yam CNC milling tshuab, tho txawv tshuab, ntau ntsug lathes, kawg milling thiab lwm yam cuab yeej tshuab. Ntxiv rau qhov yuav tsum tau ua kom lub rooj sib hloov tuaj yeem nqa qhov hnyav ntawm lub workpiece zoo, nws tseem yuav tsum tau ua kom nws qhov kev sib hloov raug raws li kev thauj khoom.

Lub turntable bearing, raws li lub hauv paus ntsiab lus ntawm lub turntable, tsis tsuas yog yuav tsum muaj ib tug siab load peev xwm, tab sis kuj muaj siab rotation raug, siab tiv thaiv overturning muaj peev xwm, thiab siab ceev muaj peev xwm thaum lub sij hawm ua hauj lwm ntawm lub turntable.

Hauv kev tsim ntawmrotary rooj, feem ntau siv bearing hom yog roughly muab faib ua hom hauv qab no:

Thrust pob bearings:cylindrical cov menyuam bearings

Thrust pob bearings tuaj yeem tiv taus qee qhov axial quab yuam, yog li cov kabmob feem ntau yog siv los dais qhov hnyav ntawm lub workpiece;Cylindrical cov menyuam bearingsNtawm qhov tod tes, feem ntau yog siv rau qhov chaw radial thiab tiv thaiv sab nraud radial rog (xws li txiav quab yuam, milling rog, thiab lwm yam). Hom kev tsim no yog siv dav thiab pheej yig heev. Vim hais tias lub pob thrust yog ib qho taw tes-hu rau cov kabmob, nws cov kabmob axial muaj peev xwm raug txwv, thiab nws tsuas yog siv rau hauv lub tshuab me me lossis nruab nrab ntawm cov cuab yeej teb cov lus. Tsis tas li ntawd, lubrication ntawm thrust pob kuj nyuaj dua.

Hydrostatic bearings:Precision cylindrical cov menyuam bearings

Hydrostatic bearing yog ib hom zawv zawg kabmob uas tso siab rau cov khoom siv sab nraud ntawm cov roj siab thiab tsim kom muaj hydrostatic load-bearing roj zaj duab xis hauv cov kabmob kom ua tiav cov kua roj lubrication. Cov kabmob hydrostatic ib txwm ua haujlwm nyob rau hauv cov kua lubrication txij thaum pib nres, yog li tsis muaj hnav, lub neej ua haujlwm ntev thiab qis pib lub zog; Tsis tas li ntawd, hom kabmob no kuj muaj qhov zoo ntawm qhov kev sib hloov siab, qhov loj roj zaj duab xis tawv, thiab tuaj yeem txo cov roj zaj duab xis oscillation. Precision cylindrical roller bearings muaj lub peev xwm zoo radial bearings, thiab vim yog siv cov bearings precision, kev sib hloov qhov tseeb ntawm lub rooj teb kuj tuaj yeem lav tau zoo. Cov rooj teb uas siv cov qauv tsim no tuaj yeem tiv taus lub zog axial siab heev, qee qhov hnyav tshaj 200 tons thiab muaj ib txoj kab uas hla ntawm ntau tshaj 10 meters. Txawm li cas los xij, hom kev tsim no kuj muaj qee qhov tsis txaus, vim tias cov kabmob hydrostatic yuav tsum tau nruab nrog cov roj tshwj xeeb los muab cov roj siab, kev saib xyuas yog qhov nyuaj, thiab tus nqi kuj tseem siab.

Hla cov menyuam bearings

Daim ntawv thov hla cov menyuam bearings ntawm turntables kuj tseem muaj. Hla cov menyuam bearings yog tus cwj pwm los ntawm ob txoj kev sib tw hauv cov kabmob, ob kab ntawm cov kabmob sib dhos. Piv rau cov tsoos thrust bearing radial centering bearing ua ke,hla cov menyuam bearingsyog compact, compact thiab simplify lub rooj tsim, yog li txo tus nqi ntawm turntable.

Tsis tas li ntawd, vim qhov optimized preload, cov bearings muaj ib tug high degree ntawm txhav, uas ua kom lub nruj thiab precision ntawm lub turntable. Ua tsaug rau kev tsim ntawm ob kab ntawm cov kab hla hla, qhov ua tau zoo ntawm cov kabmob tuaj yeem nce ntxiv, yog li cov kabmob no muaj kev tiv thaiv siab rau lub sijhawm dhau los. Hauv cov menyuam bearings, muaj ob hom: thawj yog cylindrical hla cov menyuam bearings, thiab qhov thib ob yog tapered hla cov menyuam bearings. Feem ntau, cylindrical hla cov menyuam bearings tsis tshua kim tshaj tapered hla cov menyuam bearings thiab yog haum rau turntable daim ntaub ntawv nrog tsawg speeds; Lub tapered crossed roller bearing tau txais cov qauv dawb dov ntawm cov menyuam tapered, yog li hom kabmob no muaj:

• Kev khiav hauj lwm siab

• Muaj peev xwm ceev

• Txo cov ncej ntev thiab cov nqi machining, txwv kev hloov pauv hauv geometry vim thermal expansion

• Nylon divider, tsawg lub sij hawm ntawm inertia, qis pib torque, yooj yim los tswj angular indexing

• Optimized preload, siab nruj thiab qis runout

• Tawm kev sib cuag, siab tawv, siab precision ntawm kev coj cov menyuam ua haujlwm

• Carburized steel muab kev cuam tshuam zoo heev thiab hnav tsis kam

• Yooj yim tab sis zoo-lubricated

Thaum mounting cov bearings, tus neeg muas zaub tsuas yog yuav tsum tau preload lub crossed roller bearings rau qhov pom zoo qhov tseem ceeb, es tsis yog yuav tsum muaj ib tug complex mounting kev hloov kho raws li hydrostatic bearings. Hla cov menyuam bearings yog ib qho yooj yim rau nruab thiab yooj yim los kho tus thawj installation daim ntawv los yog txoj kev txij nkawm. Hla cov menyuam bearings yog tsim rau txhua hom ntsug lossis kab rov tav tho txawv tshuab, nrog rau kev siv xws li ntsug mills, ntsug tig thiab loj iav milling tshuab.

Raws li cov ntsiab lus tseem ceeb ntawm spindle thiab turntable ntawm lub tshuab cuab yeej, cov kabmob plays lub luag haujlwm tseem ceeb hauv kev ua haujlwm ntawm lub tshuab cuab yeej. Txhawm rau kom muaj peev xwm xaiv qhov loj thiab hom kabmob, peb yuav tsum xav txog ntau yam kev khiav haujlwm, xws li kev khiav ceev, lubrication, mounting type, spindle stiffness, raug thiab lwm yam yuav tsum tau. Raws li deb ntawm cov kabmob nws tus kheej muaj kev txhawj xeeb, nws tsuas yog los ntawm kev nkag siab tag nrho nws cov qauv tsim thiab qhov ua tau zoo thiab qhov tsis zoo uas peb tuaj yeem nqa tawm qhov kev ua tau zoo tshaj plaws ntawm cov kabmob.
