Lub peev xwm ntawm cov roj granite bearings yog dab tsi?

Hauv kev lag luam tsim khoom, cov cuab yeej siv tshuab yog cov khoom siv tseem ceeb uas ua rau muaj peev xwm tsim cov khoom siv thiab cov khoom siv raug. Ib qho tseem ceeb ntawm cov cuab yeej siv tshuab yog lub spindle, uas nqa cov cuab yeej txiav thiab tig ntawm qhov ceev ceev kom ua tiav cov haujlwm machining. Lub spindle yuav tsum tau teeb tsa rau ntawm cov bearings uas tuaj yeem txhawb nws qhov hnyav thiab tiv taus lub zog tsim thaum lub sijhawm machining.

Ib txwm muaj, cov kabmob pob thiab cov kabmob menyuam yog cov hom kabmob uas siv ntau tshaj plaws hauv cov cuab yeej siv tshuab. Txawm li cas los xij, nrog rau qhov xav tau ntau ntxiv rau qhov tseeb thiab kev ua tau zoo dua, cov hom kabmob tshiab tau tsim, xws li cov kabmob roj. Cov kabmob roj yog cov kabmob tsis sib cuag uas siv cov roj nyias nyias, feem ntau yog cua lossis nitrogen, los txhawb lub ntsiab lus tig. Lawv muaj ntau qhov zoo dua li cov kabmob ib txwm muaj, xws li kev sib txhuam qis dua, muaj peev xwm ceev dua, thiab kev co zoo dua.

Ib yam khoom siv uas tau siv ua cov khoom siv roj hauv cov cuab yeej siv tshuab yog granite. Cov kabmob roj granite muaj ntau yam khoom tshwj xeeb uas ua rau lawv yog qhov kev xaiv zoo rau kev siv ua haujlwm siab. Granite yog cov khoom siv ntuj tsim los ntawm magma txias, thiab nws muaj cov qauv noob zoo heev thiab sib xws. Qhov no ua rau nws tiv taus kev hnav thiab kev hloov pauv, txawm tias nyob hauv cov khoom hnyav thiab kev kub ceev.

Cov roj granite bearings kuj muaj qhov sib piv ntawm qhov hnyav thiab qhov hnyav siab heev, uas txhais tau tias lawv tuaj yeem txhawb nqa qhov hnyav loj nrog qhov tsawg kawg nkaus deflection. Qhov no yog qhov tseem ceeb tshwj xeeb hauv cov cuab yeej siv tshuab, qhov twg lub spindle tuaj yeem hnyav ntau pua kilograms thiab yuav tsum tau mounted nrog qhov tseeb siab. Tsis tas li ntawd, granite muaj qhov coefficient qis heev ntawm thermal expansion, uas txhais tau tias nws yuav tsis tshua muaj deform vim muaj kev hloov pauv ntawm qhov kub thiab txias. Qhov no yog qhov tseem ceeb hauv cov cuab yeej siv tshuab, qhov twg qhov sib txawv ntawm qhov kub thiab txias tuaj yeem ua rau muaj kev hloov pauv tseem ceeb hauv qhov ntev ntawm cov khoom raug machined.

Lub peev xwm ntawm cov pob zeb granite roj bearings nyob ntawm ntau yam, xws li qhov loj thiab cov duab ntawm cov kabmob, cov xwm txheej ua haujlwm (kev ceev, kub, siab), thiab cov khoom siv ntawm granite. Feem ntau, cov pob zeb granite roj bearings tuaj yeem txhawb nqa cov khoom thauj xws li ob peb Newtons mus rau ob peb kilo-Newtons, nyob ntawm qhov loj thiab tsim ntawm cov kabmob. Lawv kuj tuaj yeem ua haujlwm ntawm qhov ceev txog li ntau kaum txhiab tus revolutions ib feeb, uas yog siab dua li cov pob ib txwm muaj lossis cov menyuam bearings.

Xaus lus, cov roj granite bearings yog ib qho thev naus laus zis zoo rau kev siv ceev ceev thiab siab-precision hauv cov cuab yeej siv tshuab. Lawv muaj ntau yam zoo dua li cov bearings ib txwm muaj, xws li kev sib txhuam qis dua, kev ua haujlwm ceev dua, thiab kev co zoo dua. Lub peev xwm ntawm cov roj granite bearings nyob ntawm ntau yam, tab sis lawv tuaj yeem txhawb nqa cov khoom thauj siab thiab ua haujlwm ntawm kev ceev ceev. Nrog kev tshawb fawb thiab kev txhim kho txuas ntxiv, cov roj granite bearings yuav dhau los ua ib qho khoom siv hauv cov cuab yeej siv tshuab yav tom ntej.
