Dab tsi yog cov kabmob muaj peev xwm ntawm granite roj bearings?

Hauv kev tsim kev lag luam, tshuab cov cuab yeej yog cov khoom tseem ceeb uas ua kom cov khoom siv precision thiab qhov chaw. Ib qho tseem ceeb ntawm cov cuab yeej siv tshuab yog spindle, uas nqa cov cuab yeej txiav thiab tig ntawm kev kub ceev kom ua cov kev ua haujlwm. Cov ntxaiv yuav tsum tau mounted rau bearings uas tuaj yeem txhawb nws qhov hnyav thiab tiv thaiv cov rog tsim thaum lub sijhawm machining.

Kev lig kev cai, pob bearings thiab cov menyuam bearings tau siv feem ntau siv hom kabmob hauv cov cuab yeej hauv tshuab. Txawm li cas los xij, nrog rau kev nce qib siab dua rau cov kev ua tiav ntau dua thiab kev ua tau zoo, tshiab hom bearings tau tsim, xws li muaj roj bearings. Cov pob roj carbon bearings yog tsis tiv tauj cov kabmob uas siv cov yeeb yaj kiab nyias nyias ntawm cov roj, feem ntau yog huab cua lossis nitrogen, los txhawb lub caij tig. Lawv muab ob peb qhov zoo dua cov bearings, xws li txo qis kev sib txhuam, ntau dua cov peev xwm ceev, thiab paug kom zoo dua.

Ib cov khoom uas tau siv tau zoo raws li cov khoom siv roj roj cov khoom siv hauv cov cuab yeej hauv cov cuab yeej yog granite. Cov roj av granite muaj ob peb cov khoom uas ua rau lawv xaiv zoo nkauj rau cov ntawv thov kev ua tau zoo. Granite yog cov khoom siv ntuj tsim los ntawm cov qauv txias kom txias, thiab nws muaj cov qauv grain zoo heev. Qhov no ua rau nws tiv taus hnav thiab deformation, txawm tias nyob hauv cov nra hnyav thiab kev kub ceev.

Cov roj av granite tseem muaj qhov sib zog nruj heev-rau-lub cev sib npaug, uas txhais tau tias lawv tuaj yeem txhawb nqa lub cev hnyav nrog tsawg heev deflection. Qhov no yog qhov tshwj xeeb tshaj nyob rau hauv cov cuab yeej siv tshuab, qhov chaw ntxaiv tuaj yeem hnyav li ob peb puas kilograms thiab yuav tsum tau ntsuas nrog qhov ntsuas siab. Tsis tas li ntawd, Granite muaj qhov tsawg heev coefficient ntawm thermal expansion, uas txhais tau tias nws tsis tshua muaj kev puas tsuaj vim kev hloov pauv kub. Qhov no yog qhov tseem ceeb hauv cov cuab yeej siv tshuab, qhov twg kub hloov tuaj yeem ua rau kev hloov pauv tseem ceeb hauv qhov ntev ntawm cov khoom siv.

Cov kabmob muaj peev xwm ntawm cov pob zeb granite nyob ntawm ntau yam, xws li qhov loj me thiab cov kev ua haujlwm ntawm cov yam ntxwv (ceev, siab), thiab cov khoom siv ntawm granite. Feem ntau, cov kabmob Granite tuaj yeem txhawb nqa cov khoom siv los ntawm ob peb kilo-newTons, nyob ntawm qhov loj me thiab tsim ntawm cov kabmob. Lawv tseem tuaj yeem ua haujlwm ntawm kev nrawm txog ob peb lub kaum tawm txhiab tus revolutions ib feeb, uas yog ntau dua li cov menyuam yaus pob lossis cov menyuam kabmob.

Hauv kev xaus, cov khoom siv roj granite yog cov thev naus laus zis rau kev siv cov ntawv thov kev ceev thiab siab-precision cov ntawv thov hauv cov cuab yeej siv tshuab. Lawv muab ob peb qhov zoo dua cov bearings, xws li txo qis kev sib txhuam, ntau dua cov peev xwm ceev, thiab paug kom zoo dua. Cov kabmob muaj peev xwm ntawm cov pob zeb granite nyob ntawm ntau yam, tab sis lawv tuaj yeem txhawb nqa cov nra hnyav thiab ua haujlwm ntawm kev kub ceev. Nrog txuas ntxiv kev tshawb fawb thiab kev loj hlob, cov pob zeb granite yuav dhau los ua cov qauv hauv cov cuab yeej siv tshuab ntawm lub neej yav tom ntej.
