Cov menyuam chainsyog cov khoom tseem ceeb hauv ntau lub tshuab siv tshuab, muab kev txhim khu kev qha thiab kev xa hluav taws xob zoo. Cov chains no tau siv dav hauv ntau qhov kev lag luam suav nrog tsheb, kev tsim khoom thiab kev ua liaj ua teb vim lawv cov kav ntev thiab muaj peev xwm los tuav cov khoom hnyav. Txawm li cas los xij, txhawm rau ua kom pom kev ua tau zoo thiab siv tau ntev, cov qauv tshuaj xyuas tshwj xeeb yuav tsum tau ua raws. Kab lus no delves rau hauv qhov nyuaj ntawm cov menyuam chains thiab qhia txog cov txheej txheem tshuaj xyuas tseem ceeb uas yuav tsum tau ua raws li kev tswj hwm lawv txoj haujlwm.
#### Dab tsi yog cov saw hlau?
Cov saw hlau yog cov saw hlau uas feem ntau siv rau kev siv hluav taws xob xa mus rau ntau yam khoom siv hauv tsev, kev lag luam, thiab kev ua liaj ua teb. Nws muaj ib tug series ntawm luv cylindrical rollers tuav ua ke los ntawm sab kev sib txuas. Nws yog tsav los ntawm lub zog hu ua sprockets. Chains thiab sprockets ua hauj lwm ua ke los hloov lub zog hloov ntawm ib tug ncej mus rau lwm qhov, feem ntau txo qhov ceev thiab nce torque hauv cov txheej txheem.
Cov menyuam chains yog nyiam rau lawv qhov yooj yim, kev ua tau zoo thiab muaj peev xwm los tuav cov khoom hnyav. Lawv tuaj nyob rau hauv ntau qhov ntau thiab tsawg thiab configurations, txhua tus tsim los ua kom tau raws li kev ua haujlwm tshwj xeeb. Feem ntau hom muaj xws li ib leeg-strand, ob-strand, thiab triple-strand roller chains, txhua qhov muab ntau qib sib txawv ntawm lub zog thiab kav ntev.
Qhov tseem ceeb ntawm kev tshuaj xyuas cov hlua khi
Kev tshuaj xyuas tsis tu ncua ntawm koj cov saw hlau yog qhov tseem ceeb rau ntau yam:
- Kev Nyab Xeeb: Cov menyuam cov saw tsis ua haujlwm tuaj yeem ua rau muaj kev puas tsuaj loj, ua rau muaj kev nyab xeeb tseem ceeb rau cov neeg ua haujlwm thiab tshuab.
- Kev ua tau zoo: Kev tshuaj xyuas tsis tu ncua kom cov saw hlau ua haujlwm tau zoo, tswj xyuas qhov xav tau ceev thiab lub zog.
- Lub neej ntev: Kev txheeb xyuas thaum ntxov thiab kev daws teeb meem ntawm kev hnav tuaj yeem ua rau lub neej ntev ntawm cov hlua khi thiab txo qhov kev xav tau ntau zaus.
- Tus nqi siv tau: Kev tiv thaiv kev saib xyuas los ntawm kev tshuaj xyuas tsis tu ncua txuag cov nqi cuam tshuam nrog kev npaj txhij txog kev tawg thiab kho.
#### Roller chain soj ntsuam cov qauv
Txhawm rau kom tswj tau qhov kev ua tau zoo thiab kev nyab xeeb ntawm cov menyuam chains, ntau cov qauv tshuaj xyuas tau tsim. Cov qauv no muab kev taw qhia txog kev tshuaj xyuas, ntsuas thiab ntsuas qhov xwm txheej ntawm cov hlua khi. Nov yog qee qhov tseem ceeb ntawm cov qauv no:
- Kev tshuaj xyuas qhov muag
Kev tshuaj xyuas qhov muag yog thawj kauj ruam hauv kev ntsuas qhov xwm txheej ntawm koj cov saw hlau. Nws suav nrog kev tshuaj xyuas cov cim pom tseeb ntawm kev hnav, kev puas tsuaj, lossis kev sib raug zoo. Cov chaw tseem ceeb uas yuav tsum tau kuaj xyuas muaj xws li:
- Roller: Txheeb xyuas cov cim ntawm hnav, tawg lossis deformation.
- PIN: Txheeb xyuas qhov hnav, khoov lossis corrosion.
- BUSHING: Txheeb xyuas qhov hnav lossis ncab.
- Sab Vaj Huam Sib Luag: Tshawb xyuas qhov tawg, khoov, lossis lwm yam kev puas tsuaj.
- Sprockets: Xyuas kom cov hniav tsis hnav lossis puas thiab mesh zoo nrog cov saw hlau.
- Kev ntsuas ntawm chain elongation
Chain elongation yog ib qho teeb meem uas tshwm sim vim hnav ntawm tus pin thiab bushing. Nyob rau tib lub sijhawm, qhov kev hnav no tuaj yeem ua rau cov saw hlau stretch, ua rau kev ua haujlwm tsis zoo thiab tsis ua haujlwm. Ib qho kev sim rau cov saw elongation suav nrog ntsuas qhov ntev ntawm tus lej ntawm cov saw txuas thiab muab piv rau qhov ntev ntev. Qhov kev siv tau elongation txwv feem ntau yog nyob ib ncig ntawm 2-3% ntawm qhov qub ntev. Yog tias qhov elongation dhau qhov kev txwv no, cov saw hlau yuav tsum tau hloov.
- Lubrication Check
Kev lubrication kom zoo yog qhov tseem ceeb rau kev ua haujlwm du ntawm cov menyuam chains. Thaum lub sij hawm soj ntsuam, xyuas cov qib lubrication thiab xyuas kom cov saw hlau yog lubricated txaus. Lub lubrication tsis txaus tuaj yeem ua rau muaj kev sib txhuam ntxiv, hnav thiab thaum kawg tsis ua haujlwm. Siv cov roj nplua nyeem pom zoo thiab ua raws li cov chaw tsim khoom lub sijhawm lubrication cov lus qhia.
- Tension thiab Alignment
Kev nruj nruj thiab kev sib raug zoo yog qhov tseem ceeb rau kev ua haujlwm zoo ntawm cov menyuam chains. Thaum kuaj xyuas, xyuas cov saw nro kom paub tseeb tias nws tsis nruj heev los yog xoob dhau. Cov saw hlau uas nruj dhau tuaj yeem ua rau hnav thiab ua rau cov khoom siv ntau dhau, thaum cov saw hlau uas xoob tuaj yeem ua rau plam thiab ua haujlwm tsis zoo. Tsis tas li ntawd, xyuas kom cov saw hlau zoo sib xws nrog cov sprockets kom tsis txhob hnav tsis sib xws thiab muaj peev xwm ua rau puas tsuaj.
- Hnav ntsuas
Kev ntsuas hnav muaj xws li xyuas qhov tuab ntawm cov menyuam, pins thiab bushings. Qhov no tuaj yeem ua tiav siv calipers lossis micrometers. Sib piv cov kev ntsuas rau cov chaw tsim khoom tshwj xeeb los txiav txim siab seb qhov twg yog nyob rau hauv kev txwv tsis pub hnav. Yog tias hnav tshaj qhov txwv, cov khoom cuam tshuam yuav tsum tau hloov.
- Kev qaug zog thiab Corrosion tshuaj xyuas
Kev qaug zog thiab corrosion tuaj yeem cuam tshuam rau cov menyuam saw kev ua haujlwm thiab lub neej. Thaum lub sij hawm soj ntsuam, nrhiav cov cim ntawm kev qaug zog, xws li cov kab nrib pleb los yog tawg ntawm sab panels lossis pins. Tsis tas li ntawd, tshawb xyuas corrosion, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig uas cov saw hlau raug rau cov dej noo lossis tshuaj lom neeg. Corrosion tuaj yeem ua rau cov saw tsis muaj zog thiab ua rau tsis ua haujlwm ntxov ntxov.
- Kev tshuaj xyuas Sprocket
Sprockets ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm ntawm cov menyuam chains. Thaum kuaj xyuas, xyuas cov sprocket rau cov cim ntawm kev hnav, xws li cov hniav sib tsoo lossis hnav. Xyuas kom tseeb tias lub sprocket tau zoo sib xws nrog cov saw thiab tsis muaj kev ua si ntau dhau los yog wobble. Hnav los yog puas sprockets yuav tsum tau hloov los tiv thaiv kev puas tsuaj ntxiv.
nyob rau hauv xaus
Roller chains yog ib qho tseem ceeb hauv ntau lub tshuab siv tshuab, muab kev txhim khu kev qha thiab ua haujlwm tau zoo. Txawm li cas los xij, txhawm rau ua kom pom kev ua tau zoo thiab siv tau ntev, cov qauv tshuaj xyuas tshwj xeeb yuav tsum tau ua raws. Kev tshuaj xyuas tsis tu ncua, kev ntsuas cov saw elongation, kev kuaj xyuas lubrication, kev ntsuas nruj thiab kev sib dhos, kev ntsuas kev hnav, thiab kev qaug zog thiab kev kuaj xyuas corrosion yog txhua yam tseem ceeb ntawm kev tswj cov menyuam chains.
Los ntawm kev ua raws li cov qauv tshuaj ntsuam xyuas no, cov neeg ua haujlwm tuaj yeem txheeb xyuas thiab daws cov teeb meem tshwm sim thaum ntxov, ua kom muaj kev nyab xeeb, kev ua tau zoo thiab kev ua haujlwm ntev ntawm lawv cov menyuam chains. Qhov kev tiv thaiv zoo no tsis yog tsuas yog txhim kho kev ua haujlwm ntawm cov tshuab siv tshuab, tab sis kuj txo cov kev pheej hmoo ntawm kev poob siab thiab kev kho tus nqi. Thaum kawg, ua raws li cov qauv tshuaj ntsuam xyuas no yog ib qho tseem ceeb hauv kev ua kom muaj txiaj ntsig thiab kev ntseeg siab ntawm cov hlua khi rau ntau yam kev siv hauv kev lag luam.
