"Dab tsi yog qhov txawv ntawm pob bearing vaj tse los ntawm cov qauv bearing vaj tse?" "Dab tsi precision thiab rigidity qauv yuav tsumpob bearing vaj tseRaws li kev sib ntsib rau cov khoom siv precision?" "Yuav ua li cas yog tias lub pob bearing vaj tse tsis txaus rigidity nyob rau hauv hnyav loads?" Raws li ib tug kws pab tswv yim nrog rau kaum xyoo ntawm kev txawj ntse nyob rau hauv kis tau tus mob Cheebtsam, cov lus nug no tshwm sim los ntawm ib qho kev to taub yuam kev ntawm cov yam ntxwv tseem ceeb ntawm lub pob bearing vaj tse. Qhov tseeb qhov chaw thiab siab - kev txhawb nqa nruj nws qhov kev txiav txim siab qhov sib txawv ntawm qhov sib txawv, thaum nws qhov kev nruj nruj ua rau deformation tsis kam-ob qho tib si cuam tshuam ncaj qha rau cov khoom siv machining raug, kev ua haujlwm ruaj khov, thiab kev pabcuam lub neej ua haujlwm ib zaug dhau 30,000 yuan nyob rau hauv rework poob ntau tshaj 0.0. low-precision pob bearing vaj tse nyob Conversely, cov vaj tse raug phim rau qhov raug thiab rigidity stabilized cov cuab yeej positioning raug ntawm ± 0.003mm, ua tiav ob xyoos tas mus li, txhaum{13}}kev ua haujlwm pub dawb Hnub no, ua raws li 7-kauj ruam lub ntsiab lus piav qhia nyob rau hauv "Arrhentic" qhov chaw nyob.Pob Bearing Vaj?” Thaum nkag siab zoo txog nws cov kev ntsuas qhov tseeb thiab kev nruj nruj, muab cov lus qhia ua tiav los ntawm kev xaiv mus rau daim ntawv thov.
Kauj Ruam 1: Phau Ntawv Qhia Txog Pob Bearing Housings (Precision & Rigidity)
Txhais cov ntsiab lus tseem ceeb - Ua ntej nkag siab "Yuav ua li cas lub Pob Bearing Housing yog dab tsi thiab nws daws teeb meem dab tsi"
Ua ntej tshawb nrhiav qhov tseeb thiab kev nruj, qhia meej txog qhov tseem ceeb ntawm daim ntawv thov scenarios ntawm lub pob bearing vaj tse, raws li qhov tseem ceeb ntawm kev ua tau zoo xav tau sib txawv ntawm cov ntsiab lus sib txawv:
Dab tsi yog pob bearing vaj tsev? Nws cov haujlwm tseem ceeb yog dab tsi?
Lub pob bearing vaj tse ua ke nrog lub pob bearing (dov kev sib txhuam, tsis muaj zog) nrog lub hauv paus ua los ntawm cov ntaub ntawv xws li cam khwb cia hlau lossis steel phaj. Nws peb lub luag haujlwm tseem ceeb yog: txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau coaxiality thiab qhov tseeb ntawm qhov chaw; xa cov khoom thauj los ntawm kev faib cov radial thiab axial rog los ntawm cov ncej mus rau cov khoom siv; Yooj yim installation los ntawm kev txo cov kev sib dhos yuam kev los ntawm cov qauv tsim qauv.
Dab tsi ntawm daim ntawv thov scenario koj muaj? Puas yog koj qhov kev xav tau tseem ceeb precision lossis rigidity?
Qhov tseem ceeb ntawm kev ua tau zoo sib txawv ntawm cov xwm txheej sib txawv, yuav tsum tau ua kom pom tseeb:
Precision kis scenarios:Cov ntsiab lus tseem ceeb yog "siab precision + tsis tshua muaj kev sib txhuam."
