Qhia rolls qhia thiab tsav cov xov hlau thiab cov ntaub hauv qhov ntub kawg thiab cov tshuab ziab khaub ncaws ntawm lub tshuab ntawv. Thaum cov lus qhia yob hauv ob ntu siv tib hom bearings, cov txheej txheem lubrication thiab sealing txawv raws li daim ntawv thov tshwj xeeb. Hauv cov tshuab ntawv laus, roj lubrication feem ntau yog siv rau qhov kawg ntub, thaum roj lubrication yog siv rau lub tshuab ziab khaub ncaws. Nyob rau hauv cov tshuab ntawv niaj hnub, circulating roj lubrication yog ua hauj lwm nyob rau hauv ob qho tib si seem; Txawm li cas los xij, vim muaj qhov sib txawv ntawm kev ua haujlwm, cais cov roj siv hluav taws xob yuav tsum muaj rau qhov ntub dej kawg thiab cov tshuab ziab khaub ncaws.
Cov tshuab loj dua feem ntau ua haujlwm ntawm qhov nrawm dua. Yog li ntawd, bearings nrog tapered bores yog mounted ncaj qha mus rau tapered yob phau ntawv.
1. Ntug Ntug Ntug
Cov kabmob ntawm qhov chaw sib txawv hauv lub tshuab ntawv yog raug rau qhov sib txawv ntawm thermal cuam tshuam. Tshwj xeeb, thaum lub sijhawm ua haujlwm siab - siab tu, nws yog ib qho tseem ceeb kom tsis txhob muaj dej nkag mus rau hauv cov kabmob.
2. Lub tshuab ziab khaub ncaws
Lub ambient kub yog kwv yees li 95 degree, ua rau lub thermal expansion tseem ceeb, uas tso siab xav tau ntawm lubrication. Cov kabmob ua haujlwm kub tuaj yeem ncav cuag 115 degree.
