Cov saw hlau yog ib qho tseem ceeb hauv ntau lub tshuab, txij li tsheb kauj vab mus rau cov tshuab lag luam. Kev paub yuav ua li cas thiaj li loj tau cov saw hlau rau ib qho kev siv tshwj xeeb yog qhov tseem ceeb rau kev ua haujlwm zoo tshaj plaws thiab lub neej ua haujlwm. Hauv tsab xov xwm blog no, peb yuav tshawb nrhiav cov ntsiab lus tseem ceeb uas yuav tsum tau ua kom raug qhov loj ntawm koj cov saw hlau.
Kawm txog cov npe ntawm cov saw hlau:
Ua ntej peb yuav kawm txog cov txheej txheem ntawm kev ntsuas qhov loj ntawm cov saw hlau, cia peb kawm txog cov npe ntawm cov saw hlau. Cov saw hlau feem ntau yog txheeb xyuas los ntawm cov lej thiab cov ntawv raws li hom ntawv tshwj xeeb, xws li 40, 50 lossis 60.
Tus lej thawj qhia txog qhov nrug, uas yog hais txog qhov deb ntawm qhov chaw nruab nrab ntawm txhua tus pin. Tus lej thib ob qhia txog qhov dav ntawm lub roller lossis qhov dav ntawm saw hlau hauv yim ntawm ib nti. Piv txwv li, ib txoj saw hlau 40 muaj qhov nrug ntawm 0.50 nti thiab ib txoj saw hlau 50 muaj qhov nrug ntawm 0.625 nti.
Txheeb xyuas qhov loj ntawm cov saw hlau:
Tam sim no peb nkag siab txog cov hauv paus ntawm cov npe ntawm cov saw hlau, cia peb txav mus rau qhov txiav txim siab qhov loj me.
1. Xam qhov suab:
Pib los ntawm kev suav tus naj npawb ntawm cov qhov sib txawv ntawm cov menyuam hauv cov saw hlau, tsis suav nrog ib nrab txuas. Lub suab muaj cov txuas sab hauv, cov txuas sab nraud thiab cov menyuam txuas lawv. Yog tias lub suab khib, cov saw hlau yuav muaj ib nrab txuas, uas yuav tsum suav tias yog ib nrab suab.
2. Ntsuas qhov deb:
Tom qab txiav txim siab tus lej ntawm lub suab, ntsuas qhov deb ntawm qhov chaw nruab nrab ntawm ob lub pins uas nyob ib sab. Qhov kev ntsuas no sawv cev rau lub suab thiab yuav tsum phim lub npe ntawm cov saw hlau. Piv txwv li, #40 saw hlau muaj lub suab ntawm 0.50 ntiv tes.
3. Txheeb xyuas qhov dav:
Yuav kom paub qhov dav ntawm koj cov saw hlau, siv lub caliper uas ntsuas tau qhov deb ntawm cov phaj sab hauv lossis qhov dav ntawm lub roller. Nco ntsoov tias qhov dav yog ntsuas hauv ib feem yim ntawm ib nti, yog li qhov ntsuas ntawm 6/8″ txhais tau tias lub roller yog 3/4″ dav.
4. Xyuas seb lub npe ua haujlwm yog dab tsi:
Tej cov saw hlau uas siv rau cov menyuam yuav muaj lwm lub npe, xws li ib txoj saw hlau (SS) lossis ob txoj saw hlau (DS), los qhia seb lawv puas yog tsim los rau ib txoj saw hlau lossis ntau txoj saw hlau. Nco ntsoov txheeb xyuas tej yam tshwj xeeb uas yuav cuam tshuam rau kev ua haujlwm ntawm txoj saw hlau.
Saib daim ntawv qhia txog Roller Chain Reference Table:
Txawm hais tias cov kauj ruam saum toj no feem ntau txaus rau feem ntau qhov loj ntawm cov saw hlau, qee zaum, cov saw hlau yuav muaj tus qauv tsim tshwj xeeb lossis qhov loj tsis zoo. Hauv cov xwm txheej zoo li no, nws yog ib qho tseem ceeb kom sab laj nrog Roller Chain Reference Table, uas muab cov npe ntawm cov saw hlau, qhov loj me thiab cov lus qhia ntsig txog.
Los ntawm kev saib cov lus qhia no, koj tuaj yeem kuaj xyuas koj cov kev ntsuas thiab xyuas kom meej tias koj tau teeb tsa qhov loj ntawm cov saw hlau rau koj daim ntawv thov tshwj xeeb.
xaus lus:
Kev ntsuas qhov loj ntawm cov saw hlau yog qhov tseem ceeb rau kev ua kom cov txheej txheem ua haujlwm tau zoo thiab ua haujlwm tau zoo. Los ntawm kev ua raws li cov kauj ruam saum toj no thiab xa mus rau daim ntawv qhia txog cov saw hlau, koj tuaj yeem txheeb xyuas qhov siab, qhov dav thiab txhua qhov kev xaiv tshwj xeeb ntawm cov saw hlau. Nco ntsoov tias kev ntsuas kom raug thiab kev saib xyuas kom meej yog qhov tseem ceeb rau kev ua haujlwm zoo tshaj plaws thiab lub neej ntev. Yog li ntawd, siv sijhawm los ntsuas thiab txheeb xyuas qhov loj ntawm koj cov saw hlau ua ntej ua qhov hloov pauv lossis hloov kho.
