Hauv kev tsim kho tshuab, qee cov qauv tsim tau txais lub koob npe nrov los ntawm kev sib npaug zoo meej ntawm daim ntawv thiab kev ua haujlwm. Lub pob sib sib zog nqus ib kab yog ib qho cim zoo li no. Ua kev zoo siab rau nws qhov kev ua tau zoo thiab kev ua haujlwm tau zoo, cov khoom no yog ib chav kawm zoo hauv kev daws cov teeb meem kev txav mus los nyuaj nrog kev daws teeb meem yooj yim heev. Tab sis cov ntsiab cai tsim tshwj xeeb twg ua rau lub pob sib sib zog nqus ua haujlwm tau zoo, thiab koj xaiv qhov yog li cas?
Kev rhuav tshem tus qauv tsim: Qhov uas yooj yim ntsib kev ua tau zoo
Cov kabmob pob sib sib zog nqus ib kab yog tsim los ntawm kev ua tib zoo saib xyuas ib puag ncig lub tswv yim tseem ceeb: txoj kab sib sib zog nqus uas tsis muaj kev cuam tshuam. Cov grooves no, uas tau ua kom raug rau hauv ob lub nplhaib sab hauv thiab sab nraud, yog qhov tseem ceeb ntawm cov kabmob. Lawv tso cai rau ntau lub pob kom ntxig, uas yog qhov tseem ceeb rau nws lub peev xwm thauj khoom siab.
Tus qauv tsim no muab ntau qhov txiaj ntsig ntawm kev ua tau zoo:
Kev Siv Tau Ntau Yam Rau Kev Thauj Khoom Radial Thiab Axial: Cov qhov sib sib zog nqus thiab sib haum ua rau cov kabmob no tuav tau cov khoom thauj radial loj. Qhov tseem ceeb, tib lub geometry no tso cai rau nws tuav cov khoom thauj axial (thrust) nruab nrab los ntawm ob qho kev taw qhia, uas yog lub peev xwm uas ua rau nws txawv ntawm ntau lwm hom kabmob.
Kev Muaj Peev Xwm Ceev: Nrog rau qhov poob qis tshaj plaws ntawm kev sib txhuam thiab lub peev xwm ua kom raug, lub pob sib sib zog nqus yog qhov kev xaiv zoo heev rau cov ntawv thov ceev xws li lub cev muaj zog hluav taws xob thiab turbochargers.
Kev Ruaj Khoov thiab Kev Ntseeg Tau: Cov qauv kev sib tw tas mus li muab kev ruaj khov zoo heev, uas ua rau nws tiv taus kev ntxhov siab ntawm kev ua haujlwm tas mus li hauv cov chaw nyuaj.
Ib Daim Ntawv Qhia Txog Kev Xaiv: Cov Kev Xav Tseem Ceeb
Kev xaiv cov kabmob sib sib zog nqus yog qhov tseem ceeb rau kev ua haujlwm zoo tshaj plaws thiab lub neej ntev. Nov yog cov yam tseem ceeb uas cov engineers yuav tsum xav txog:
Cov Kev Cai Rau Kev Thauj Khoom thiab Kev Ceev: Xam qhov loj thiab hom (radial vs. axial) ntawm cov khoom thauj, nrog rau qhov ceev ua haujlwm. Qhov no yog thawj kauj ruam hauv kev txo qhov loj me thiab koob ntawm cov kabmob (piv txwv li, 60, 62, 63 koob uas qhia txog qhov loj me thiab peev xwm).
Chav Kawm Tseeb: Tsis yog txhua lub bearings yog tsim sib npaug. Cov qauv zoo li ABEC (Annular Bearing Engineers' Committee) txhais cov qib kev kam rau siab. Chav kawm tseeb dua (piv txwv li, ABEC 3, 5, 7) muab suab nrov qis dua, kev co qis dua, thiab kev khiav raug dua, uas yog qhov tseem ceeb rau cov ntawv thov xws li cov khoom siv kho mob lossis cov spindles zaus siab.
Hom Tawb thiab Khoom Siv: Lub tawb, uas cais cov pob, tuaj yeem ua los ntawm cov hlau stamped, tooj dag machined, lossis polymers zoo li PEEK. Qhov kev xaiv cuam tshuam rau qhov ceev tshaj plaws, suab nrov, thiab kev tiv taus cov tshuaj lom neeg lossis thermal cuam tshuam.
Kev Kaw thiab Kev Siv Lubrication: Qhov chaw ua haujlwm qhia tias yuav tsum muaj cov foob (cov foob roj hmab sib chwv) lossis cov ntaub thaiv (cov ntaub thaiv hlau tsis sib chwv) kom tiv thaiv cov pa phem thiab cov roj nkag mus. Hom kev siv lubrication thawj zaug (roj lossis roj) yuav tsum sib xws nrog qhov kub thiab txias ua haujlwm.
Xaus Lus: Kev coj ua zoo rau txoj haujlwm
Cov kabmob pob ib kab sib sib zog nqus yog ib qho pov thawj ntawm kev tsim kho zoo heev. Los ntawm kev nkag siab txog nws cov ntsiab cai tsim thiab cov yam tseem ceeb hauv cov txheej txheem xaiv, cov neeg tsim qauv thiab cov kws tshaj lij kev saib xyuas tuaj yeem ua kom lawv siv cov khoom tseem ceeb no kom tag nrho nws lub peev xwm, lav qhov kev ntseeg tau thiab kev ua haujlwm zoo hauv txhua daim ntawv thov.
