Thaum tsim ib lub rooj sib dhos uas tig tau, cov engineers feem ntau ntsib qhov kev xaiv tseem ceeb ntawm ob hom pob bearing tseem ceeb: cov pob bearing sib sib zog nqus thiab cov pob bearing sib txuas tshwj xeeb. Txawm hais tias ob qho tib si yog qhov tseem ceeb, kev nkag siab txog lawv cov yam ntxwv sib txawv yog qhov tseem ceeb rau kev ua haujlwm zoo tshaj plaws ntawm lub tshuab. Yog li, dab tsi ua rau lawv sib txawv, thiab thaum twg koj yuav tsum teev cov pob bearing sib sib zog nqus txheem?
Qhov Sib Txawv Tseem Ceeb: Raceway Geometry thiab Kev Tswj Xyuas Khoom
Qhov sib txawv yog nyob rau hauv kev tsim ntawm cov raceways. Lub pob bearing sib sib zog nqus muaj cov raceways sib npaug, sib sib zog nqus ntawm ob lub nplhaib, uas tso cai rau nws los tswj cov khoom hnyav radial thiab cov khoom hnyav axial nruab nrab los ntawm ob qho kev taw qhia. Nws yog qhov tseem ceeb "txhua yam-rounder."
Qhov sib txawv, lub kaum sab xis sib cuag muaj cov kab sib dhos tsis sib xws, qhov twg cov nplhaib sab hauv thiab sab nraud raug tshem tawm sib piv rau ib leeg. Tus qauv tsim no tsim lub kaum sab xis sib cuag, ua rau nws tuaj yeem txhawb nqa cov khoom thauj axial siab heev hauv ib qho kev taw qhia, feem ntau ua ke nrog cov khoom thauj radial. Nws yog "tus kws tshaj lij" rau kev siv thrust.
Cov Xwm Txheej Siv: Qhov Twg Txhua Lub Bearing Zoo Tshaj Plaws
Xaiv Lub Pob Bearing Groove Sib Sib Zog Thaum:
Koj lub nra hnyav tseem ceeb yog radial.
Koj muaj cov khoom thauj axial ob txoj kev nruab nrab (piv txwv li, los ntawm kev sib txuas iav lossis kev tsis sib haum me ntsis).
Kev yooj yim, kev siv nyiaj tsim nyog, thiab kev muaj peev xwm ua haujlwm ceev ceev yog qhov tseem ceeb.
Cov ntawv thov suav nrog: lub cev muaj zog hluav taws xob, twj tso kua mis, conveyors, thiab cov khoom siv hauv tsev.
Xaiv ib qho Angular Contact Bearing Thaum:
Lub nra hnyav tseem ceeb yog axial (thrust), xws li hauv cov cuab yeej tshuab spindles, cov twj tso kua mis ntsug, lossis cov khoom txhawb nqa iav kab.
Koj xav tau qhov chaw axial meej thiab rigidity siab.
Koj siv tau lawv ua khub (rov qab rau nraub qaum lossis ntsej muag rau ntsej muag) los tswj kev thawb mus rau ob qho tib si.
Txoj Kev Sib Xyaws & Cov Kev Daws Teeb Meem Niaj Hnub
Cov tshuab niaj hnub no feem ntau siv ob qho tib si. Ib qho kev teeb tsa zoo sib xws ua ke ob lub angular contact bearings los tswj cov thrust hnyav, thaum lub pob bearing tob groove nyob rau lwm qhov hauv lub system tswj cov radial loads thiab muab axial location. Ntxiv mus, cov chaw tsim khoom tam sim no muab cov qauv "universal" lossis "X-life" uas thawb cov ciam teb kev ua tau zoo ntawm cov qauv pob bearing tob groove, ua rau cov kab ntawm ob hom rau qee qhov kev siv.
Xaus Lus: Kev Sib Txuas Qauv Tsim nrog Kev Ua Haujlwm
Qhov kev xaiv tsis yog hais txog qhov twg zoo dua, tab sis qhov twg zoo tshaj plaws rau txoj haujlwm. Lub pob sib sib zog nqus uas tsis muaj zog tseem yog qhov kev daws teeb meem rau feem ntau ntawm cov ntawv thov dav dav vim nws qhov kev sib xyaw ua ke ntawm kev ua tau ntau yam, kev pheej yig, thiab kev ntseeg siab. Rau cov xwm txheej tshwj xeeb uas muaj zog siab, lub pob sib cuag angular yog qhov kev xaiv meej. Los ntawm kev nkag siab txog qhov sib txawv tseem ceeb no, cov engineers ua kom muaj lub neej ntev, ua haujlwm tau zoo, thiab raug hauv txhua qhov kev tsim.
