1. Feem ntau, thaum lub kiv cua ntawm cov khoom siv ua haujlwm rau 1000 teev, cov roj bearing yuav tsum tau ntxiv thiab kho cov ntsia hlau ntawm cov kiv cua yuav tsum tau nruj; Qhov thib ob yog ntau yam teeb meem hauv cov tshuab ziab khaub ncaws, uas yuav tsum tau ua kom zoo.
2. Hauv qee qhov tshwj xeeb, yuav tsum tau saib xyuas cov txheej txheem tu, thiab cov txheej txheem tsim nyog yuav tsum tau txais yuav.
3. Tshawb xyuas lub lubrication ntawm lub hollow hniav tshuab kom raws sij hawm, thiab daws cov teeb meem hauv lub sij hawm yog tias pom muaj teeb meem; Kev saib xyuas yuav tsum tau them rau lubrication, thiab cov khoom txav mus los thiab cov khoom txav yuav tsum tsis tu ncua nrog cov roj lubricating (cov roj) thiab lwm yam zoo lubrication.
4. Kev tiv thaiv xeb sab hauv thiab sab nraud ntawm cov khoom siv kuj tseem ceeb dua. Kev ua haujlwm los tiv thaiv xeb yog tsuas yog kom tsis txhob muaj kev laus ntxov ntawm cov khoom siv, tib lub sijhawm cuam tshuam rau kev ua haujlwm kom qhuav, thiab xyuas kom meej lub neej kev pab cuam ntawm lub hollow hniav ziab khoom. Nws yog ib qho tsim nyog yuav tsum tau ua tib zoo saib xyuas cov khoom siv tsis tu ncua kom ntseeg tau tias kev huv ntawm tag nrho lub tshuab.
5. Nyob rau hauv cov nqe lus ntawm qhov kub thiab txias, nws yog ib qho tsim nyog yuav tsum tau ua tib zoo saib xyuas cov thermal rwb thaiv tsev ntawm lub tog raj kheej tsis tu ncua, thiab yuav tsum tau daws kom tau raws sijhawm yog tias muaj huab cua to lossis lwm yam deformation.
6. Kev kuaj xyuas lub tshuab ziab khaub ncaws yog lub hauv paus tseem ceeb rau kev siv cov cuab yeej siv kho mob. Kev saib xyuas tsis tu ncua tuaj yeem kuaj xyuas qhov txhaum ntawm lub hollow hniav tshuab ziab khaub ncaws hauv lub sijhawm, txhawm rau tiv thaiv micro-duplication thiab tiv thaiv qhov tshwm sim ntawm qhov tsis raug.
