Dab tsi yog qhov txawv ntawm daim ntawv qhia linear thiab daim ntawv qhia cov menyuam?
Linear guides thiab roller guides yog ob qho tib si siv hauv tshuab thiab khoom siv los coj cov lus qhia tawm. Lawv yog cov khoom tseem ceeb hauv ntau daim ntawv thov kev lag luam thiab kev tsim khoom, los ntawm cov neeg hlau mus rau cov tshuab conveyor. Txawm li cas los xij, muaj qhov sib txawv tseem ceeb ntawm cov kab ntawv qhia thiab cov ntawv qhia cov menyuam uas cuam tshuam rau lawv qhov kev ua tau zoo, qhov tseeb, thiab kav ntev. Hauv tsab xov xwm no, peb yuav tshawb txog qhov sib txawv tseem ceeb ntawm ob hom kev qhia no thiab seb lawv tuaj yeem cuam tshuam koj li kev tsim vaj tsev thiab kev txiav txim siab li cas.
** Kev tsim kho
Ib qho ntawm qhov sib txawv tshaj plaws ntawm cov kab ntawv qhia thiab cov ntawv qhia cov menyuam yog lawv cov kev tsim kho. Cov kev qhia tawm muaj xws li ib lub tsheb ciav hlau nyob ruaj khov thiab lub tsheb thauj mus los uas swb raws txoj kev tsheb ciav hlau ntev. Lub carriage muaj ib txheej ntawm linear bearings uas yob raws txoj kev tsheb ciav hlau grooves, muab kev sib tw thiab meej. Cov kab ntawv qhia feem ntau yog ua los ntawm cov hlau tawv lossis txhuas, thiab cov kabmob tuaj yeem ua los ntawm cov yas, ceramics, lossis hlau.
Ntawm qhov tod tes, cov lus qhia rau cov menyuam siv cov txheej txheem ntawm cov menyuam es tsis txhob siv cov kabmob linear. Cov rollers txav mus rau hauv ib lub tsheb uas muaj cov grooves los yog lem, coj cov lus tsa suab nrog kev sib txhuam tsawg. Cov rollers tuaj yeem ua cylindrical, kheej kheej, lossis tapered, nyob ntawm daim ntawv thov xav tau. Cov lus qhia rau cov menyuam' kev tsim kho ua rau lawv tsim nyog rau cov ntawv thov hnyav thiab ib puag ncig hnyav, qhov twg cov kab ntawv qhia yuav hnav sai sai.
** Load Capacity
Lwm qhov sib txawv tseem ceeb ntawm cov kab ntawv qhia thiab cov menyuam qhia yog lawv lub peev xwm thauj khoom. Cov kev qhia tawm tuaj yeem txhawb nqa cov khoom hnyav, tab sis lawv lub peev xwm thauj khoom raug txwv los ntawm qhov loj thiab tus naj npawb ntawm cov kabmob. Yog hais tias lub load tshaj lub bearings 'muaj peev xwm, cov lus qhia yuav raug kev txom nyem los ntawm kev hnav ntxov ntxov, tsis muaj tseeb, thiab txo lifespan. Cov kab ntawv qhia yog tsim rau lub teeb rau nruab nrab loads thiab nruab nrab ceev, ua rau lawv zoo tagnrho rau precision daim ntaub ntawv.
Cov ntawv qhia cov menyuam, ntawm qhov tod tes, muaj peev xwm thauj khoom ntau dua li cov lus qhia tawm vim lawv qhov sib cuag. Cov rollers faib cov khoom sib npaug ntawm thaj chaw loj dua, txo qhov kev ntxhov siab ntawm txhua yam. Cov lus qhia rau cov menyuam tuaj yeem tuav cov khoom hnyav, kev kub ceev, thiab hnyav ib puag ncig yam tsis muaj kev cuam tshuam qhov tseeb lossis kev ua haujlwm. Txawm li cas los xij, cov lus qhia rau cov menyuam yuav xav tau kev saib xyuas ntau dua li cov kab ntawv qhia kom paub meej tias lubrication kom zoo thiab tiv thaiv kev puas tsuaj lossis hnav.
** Qhov tseeb
Qhov tseeb ntawm cov lus qhia yog qhov tseem ceeb hauv ntau daim ntawv thov, tshwj xeeb tshaj yog cov uas xav tau qhov tseeb qhov chaw, ntsuas, lossis kev sib tw. Cov kab ntawv qhia feem ntau yog qhov tseeb dua li cov lus qhia rau cov menyuam vim lawv cov kab bearings '' tsim. Cov bearings yog nyob rau hauv kev sib cuag ncaj qha nrog cov rail grooves, muab ib tug high degree ntawm repeatability thiab precision. Tsis tas li ntawd, cov ntawv qhia tawm tuaj yeem nruab nrog cov yam ntxwv ntxiv xws li linear encoders, cov ntsaws ruaj ruaj, lossis cov khoom siv tiv thaiv rov qab los txhim kho qhov tseeb ntxiv.
Cov ntawv qhia cov menyuam kuj tuaj yeem ua tiav qhov raug zoo hauv ntau daim ntawv thov, tab sis lawv yuav muaj kev cuam tshuam ntau dua los ntawm cov menyuam deformation lossis misalignment. Cov chais 'cov duab thiab qhov loj tuaj yeem cuam tshuam rau cov lus qhia qhov tseeb, thiab kev tsim cov kev ua siab ntev yuav yog qhov tseem ceeb tshaj li cov lus qhia.
** Kev nruj thiab Rigidity
Qhov nruj thiab nruj ntawm daim ntawv qhia tuaj yeem cuam tshuam rau nws qhov kev ua tau zoo thiab lub neej ntev. Cov lus qhia nruj tsis tshua muaj kev vibration, deflection, los yog dabtsi yog khoov, muab smoother thiab ruaj khov zog. Cov ntawv qhia tawm thiab cov ntawv qhia cov menyuam sib txawv hauv lawv qhov kev nruj thiab nruj vim lawv cov qauv sib txawv.
Cov kab ntawv qhia feem ntau yog nruj thiab nruj dua li cov lus qhia rau cov menyuam vim lawv txoj kev tsheb ciav hlau tsis sib haum thiab cov kab tawm. Txoj kev tsheb ciav hlau qhov tawv nqaij txiav txim siab qhov kev taw qhia qhov kev nruj tag nrho, thiab cov kab bearings '' tsim tso cai rau qhov tsawg kawg nkaus deflection lossis khoov. Cov kev qhia tawm tuaj yeem muab cov kev ua haujlwm zoo tshaj plaws thiab qhov tseeb hauv cov ntawv thov uas yuav tsum muaj kev nruj nruj, xws li CNC tshuab, tuaj tos-thiab-qhov chaw, lossis kev sib koom tes ntsuas tshuab.
Cov kev taw qhia rau cov menyuam yaus, ntawm qhov tod tes, tej zaum yuav tsis tshua muaj zog thiab nruj dua li cov lus qhia tawm vim lawv cov tsheb thauj mus los thiab cov menyuam sib cuag. Cov rollers tuaj yeem deform lossis deflect nyob rau hauv hnyav loads lossis high speeds, txo cov kev taw qhia nruj. Txawm li cas los xij, cov lus qhia rau cov menyuam tuaj yeem muab cov khoom zoo dua damping dua li cov lus qhia tawm vim lawv cov kev sib cuag dov, txo qhov cuam tshuam ntawm kev poob siab thiab kev co ntawm lub tshuab cov khoom.
** Nqi thiab Kho
Thaum kawg, tus nqi thiab kev saib xyuas ntawm daim ntawv qhia tuaj yeem cuam tshuam rau tag nrho cov nqi system thiab kev ntseeg tau. Cov kab ntawv qhia thiab cov ntawv qhia cov menyuam muaj cov nqi sib txawv thiab kev saib xyuas, nyob ntawm seb lawv qhov loj me, lub peev xwm thauj khoom, qhov tseeb, thiab lwm yam.
Cov kab ntawv qhia feem ntau pheej yig dua li cov lus qhia rau cov menyuam siv lub teeb rau nruab nrab-lub luag haujlwm daim ntawv thov, tab sis lawv cov nqi yuav nce ntxiv rau cov loads siab dua lossis cov kev cai raug. Cov kev qhia tawm kuj yuav tsum tau saib xyuas tsawg dua li cov lus qhia rau cov menyuam, vim tias lawv cov kab bearings muaj kev tiv thaiv ntau dua rau kev hnav thiab kev sib kis. Cov kev taw qhia tawm tuaj yeem tsim nyog yog tias tus nqi thiab kev saib xyuas muaj kev txhawj xeeb, thiab lub peev xwm thauj khoom thiab qhov tseeb yuav tsum tsis siab.
Cov ntawv qhia cov menyuam yaus yuav kim dua li cov lus qhia tawm, tshwj xeeb tshaj yog rau cov khoom loj lossis cov ntawv thov raug siab. Cov ntawv qhia cov menyuam kuj xav tau kev saib xyuas ntau dua li cov kev qhia tawm, vim tias lawv cov menyuam tuaj yeem hnav lossis puas yog tias tsis lubricated lossis ntxuav kom zoo. Txawm li cas los xij, cov lus qhia rau cov menyuam tuaj yeem muab kev ua tau zoo thiab ua haujlwm ntev dua li cov lus qhia tawm, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig hnyav lossis kev siv hnyav.
Hauv kev xaus, ob qho tib si linear guides thiab roller guides tuaj yeem muab kev tswj xyuas kev tswj xyuas kom ntseeg tau thiab raug nyob rau hauv ntau hom kev lag luam thiab kev tsim khoom. Txawm li cas los xij, lawv cov kev tsim kho, lub peev xwm thauj khoom, qhov tseeb, qhov nruj, nruj, tus nqi, thiab kev saib xyuas yuav tsum sib txawv, thiab xaiv hom kev qhia yog nyob ntawm daim ntawv thov tshwj xeeb cov kev xav tau thiab kev txwv. Los ntawm kev nkag siab txog qhov sib txawv ntawm cov kab ntawv qhia thiab cov ntawv qhia cov menyuam, koj tuaj yeem txiav txim siab paub ntau ntxiv txog koj lub tshuab thiab cov cuab yeej tsim, ua kom pom kev ua haujlwm zoo, kev ntseeg siab, thiab kev nyab xeeb.
