Bearing clearance yog hais txog qhov sib txawv lossis qhov chaw nruab nrab ntawm cov kabmob thiab nws cov mating nto ntawm tus ncej lossis vaj tsev. Nws yog ib qho tseem ceeb rau kev txiav txim siab qhov kev ua tau zoo ntawm lub tshuab, tshwj xeeb tshaj yog nyob rau hauv cov ntaub ntawv ntawm cov khoom sib hloov xws li cav, turbines, twj thiab generators.
Qhov tsim nyog ntawm cov kabmob clearance yuav tsum tau teem rau kev ua haujlwm zoo ntawm lub tshuab. Yog tias qhov kev tshem tawm loj dhau, nws tuaj yeem ua rau lub zog txav ntawm lub ncej, uas tuaj yeem ua rau muaj kev vibration thiab suab nrov. Kev vibration ntau dhau kuj tuaj yeem ua rau kom nrawm hnav thiab tsim kua muag ntawm cov kabmob thiab lwm yam khoom, uas tuaj yeem ua rau lub cev tsis ua haujlwm.
Ntawm qhov tod tes, yog tias qhov kev tshem tawm tsawg dhau, nws tuaj yeem ua rau tsis muaj lubrication, uas tuaj yeem ua rau muaj kev sib txhuam thiab kub. Qhov no tuaj yeem ua rau hnav ceev ceev ntawm cov kabmob thiab lwm yam khoom, uas tuaj yeem ua rau tsis ua haujlwm ntxov.
Tus nqi ntawm cov kabmob clearance uas zoo rau lub tshuab yog nyob ntawm ntau yam xws li kev ceev, thauj khoom, kub, thiab lubrication system hauv kev siv. Kev tshem tawm ntawm {{0}}.001 txog 0.003 ntiv tes feem ntau suav tias tsim nyog rau feem ntau daim ntawv thov.
Kev tshem tawm cov kabmob kom zoo ua kom lub tshuab ua haujlwm zoo thiab ua haujlwm zoo, nrog lub suab nrov tsawg thiab kev co. Nws kuj tseem xyuas kom meej tias cov khoom hnav maj mam, ncua lub neej ntawm lub tshuab. Tsis tas li ntawd, kev tshem tawm txoj cai yuav pab txo qis kev siv hluav taws xob, yog li ua kom muaj txiaj ntsig thiab txo cov nqi khiav lag luam.
Hauv kev xaus, bearing clearance plays lub luag haujlwm tseem ceeb hauv kev txiav txim siab kev ua haujlwm ntawm lub tshuab. Los ntawm kev teeb tsa qhov pom kev tshem tawm, cov neeg ua haujlwm tshuab tuaj yeem txaus siab rau kev txhim kho kev ua haujlwm thiab txo tus nqi kho. Yog li ntawd, nws yog ib qho tseem ceeb ib txwm ua kom paub tseeb tias qhov tseeb bearing clearance yog siv nyob rau hauv txhua daim ntawv thov tshuab.
