Tshawb nrhiav thiab kho qhov tsis sib xws
Yuav kom tswj tau qhov kev ua tau zoo ntawm cov kabmob rau ntev li ntev tau, kev saib xyuas thiab kev tshuaj xyuas yuav tsum tau ua. Yog tias siv cov txheej txheem tsim nyog, ntau yam teeb meem ntawm cov kabmob tuaj yeem zam tau thiab kev ntseeg siab, kev tsim khoom, thiab cov nqi khiav lag luam ntawm cov khoom uas muaj cov bearings yog tag nrho cov kev txhim kho. Nws raug pom zoo tias kev saib xyuas ib ntus yuav tsum ua raws li cov txheej txheem teev tseg. Qhov kev saib xyuas ib ntus no suav nrog kev saib xyuas ntawm kev ua haujlwm, kev muab lossis hloov cov roj nplua nyeem, thiab kev tshuaj xyuas ib ntus. Cov khoom uas yuav tsum tau kuaj xyuas tsis tu ncua thaum lub sijhawm ua haujlwm suav nrog lub suab nrov, kev vibration, kub, thiab lubrication.
Yog tias pom muaj qhov tsis sib xws thaum lub sijhawm ua haujlwm, qhov laj thawj yuav tsum tau txiav txim siab thiab kev kho kom raug yuav tsum tau ua tom qab xa mus rau Table 2.
Yog tias tsim nyog, cov kabmob yuav tsum tau muab tshem tawm thiab tshuaj xyuas kom meej. Raws li cov txheej txheem rau dismounting thiab tshuaj xyuas, xa mus rau Tshooj 5, Kev Tshuaj Xyuas Cov Kabmob.
Bearing Failures thiab Countermeasures
Feem ntau, yog tias dov bearings raug siv kom raug lawv yuav muaj sia nyob rau lawv lub neej qaug zog. Txawm li cas los xij, lawv feem ntau ua tsis tiav ntxov vim kev zam tsis tau yuam kev.
Nyob rau hauv sib piv rau lub neej qaug zog, qhov tsis ua hauj lwm ntxov ntxov no yog tshwm sim los ntawm kev txhim kho tsis raug, tuav, lossis lubrication, nkag mus rau cov khoom txawv teb chaws, lossis kev tsim hluav taws xob txawv txav.
Piv txwv li, qhov ua rau ntawm qhov qhab nia ntawm tav, raws li ib qho piv txwv ntawm kev ua tsis tiav ntxov, tuaj yeem suav nrog lubrication tsis txaus, siv cov roj nplua nyeem tsis raug, lubrication tsis raug, nkag mus rau txawv teb chaws teeb meem, bearing mounting yuam kev, ntau deflection ntawm lub ncej, los yog ib qho kev sib xyaw ntawm cov no. . Yog li, nws yog qhov nyuaj los txiav txim siab qhov ua rau ntawm qee qhov ua tsis tiav ntxov.
Yog tias tag nrho cov xwm txheej ntawm lub sijhawm tsis ua haujlwm thiab dhau mus rau lub sijhawm tsis ua haujlwm raug paub, suav nrog daim ntawv thov, kev ua haujlwm, thiab ib puag ncig; tom qab ntawd los ntawm kev kawm txog qhov tsis ua haujlwm thiab nws qhov ua tau tshwm sim, qhov ua tau zoo ntawm kev ua tsis tiav yav tom ntej tuaj yeem raug txo. Feem ntau ntawm cov kabmob tsis ua haujlwm, nrog rau lawv cov laj thawj thiab kev kho kom raug, muaj nyob rau hauv Table 3.
