Nyob rau theem loj ntawm kev lag luam niaj hnub no, muaj ib qho khoom yooj yim tab sis tseem ceeb uas txhawb nqa kev ua haujlwm ntawm ntau lub tshuab, uas yog, cov saw hlau. Tsab xov xwm no yuav coj koj mus rau hauv lub ntiaj teb ntawmcov saw hlau, txij li nws txoj kev ua haujlwm mus txog rau nws lub luag haujlwm tseem ceeb hauv kev lag luam niaj hnub no. Cia peb tshawb nrhiav qhov tsis paub meej ntawm lub plawv kev lag luam no ua ke.
Keeb kwm thiab kev hloov pauv ntawm cov saw hlau
Keeb kwm ntawm cov saw hlau tuaj yeem taug qab rov qab mus rau 180 BC, thaum Tuam Tshoj tau tsim ib lub cuab yeej hu ua "chain drive" rau kev tsa cov log dej. Txawm li cas los xij, cov saw hlau tiag tiag tau tsim los ntawm Charles F. Kratzer thaum kawg ntawm xyoo pua 19th. Nws tau txhim kho cov saw hlau tiaj tiaj thiab ntxiv cov menyuam, uas tau txhim kho qhov ua tau zoo thiab lub peev xwm thauj khoom ntawm cov saw hlau.
Nrog rau kev nce qib ntawm kev hloov pauv hauv kev lag luam, ntau yam kev siv cov saw hlau tau txuas ntxiv nthuav dav. Txij li tsheb kauj vab mus rau tsheb, los ntawm cov tshuab textile mus rau cov kab tsim khoom lag luam niaj hnub, cov saw hlau muaj nyob txhua qhov chaw. Nws tus qauv tsim kuj tseem niaj hnub zoo dua los hloov kho kom haum rau qhov ceev dua thiab cov khoom thauj loj dua.
Cov qauv thiab txoj cai ua haujlwm ntawm cov saw hlau
Cov saw hlau uas muaj cov menyuam muaj ntau yam txuas, txhua yam muaj ob daim hlau saw hlau thiab ib lub menyuam. Cov hlau phaj feem ntau yog ua los ntawm hlau, thaum cov menyuam yog ua los ntawm hlau tawv kom txo qhov kev sib txhuam thiab txhim kho kev tiv thaiv kev hnav. Cov saw hlau txuas nrog cov koob thiab cov tes tsho kom ua tau ib daim uas yoog tau thiab muaj zog.
Lub hauv paus ntsiab lus ua haujlwm ntawm cov saw hlau yog raws li kev sib txhuam thiab kev sib txuas. Thaum lub zog fais fab (xws li lub cev muaj zog) tsav lub sprocket, cov hniav ntawm lub sprocket mesh nrog cov phaj saw hlau sab hauv ntawm cov saw hlau, thawb cov saw hlau txuas raws txoj kev tau teem tseg. Cov rollers dov ntawm cov saw hlau txuas thiab sprockets, txo kev sib txhuam thiab ua rau kev xa hluav taws xob zoo dua.
Cov txiaj ntsig thiab kev siv ntawm cov saw hlau
Qhov laj thawj uas cov saw hlau siv dav hauv kev lag luam yog vim muaj cov txiaj ntsig hauv qab no:
Kev ua haujlwm siab: Kev sib txhuam ntawm cov saw hlau yog tsawg dua li kev sib txhuam swb, uas txhais tau tias nws tuaj yeem xa hluav taws xob ntau dua nrog kev siv hluav taws xob tsawg dua.
Muaj peev xwm thauj khoom siab: Vim muaj cov menyuam, cov saw hlau tuaj yeem tiv taus cov khoom thauj loj thiab tsim nyog rau cov tshuab hnyav.
Lub neej ntev: Cov saw hlau zoo siv tau ntau xyoo nrog kev saib xyuas kom zoo, txo cov nqi hloov pauv.
Kev Txhim Kho: Tus qauv tsim ntawm cov saw hlau yog yooj yim thiab txhim khu kev qha, thiab lawv tuaj yeem ua haujlwm ruaj khov txawm tias nyob rau hauv qhov chaw ua haujlwm hnyav.
Cov ntawv thov ntawm cov saw hlau yog dav heev, suav nrog tab sis tsis txwv rau:
Kev lag luam tsheb: Hauv lub cav ntawm lub tsheb, cov saw hlau siv los tsav lub camshaft kom ntseeg tau tias qhov qhib thiab kaw ntawm cov li qub raug.
Tsheb kauj vab thiab maus taus: Cov saw hlau yog lub hauv paus ntawm lub kaw lus kis ntawm tsheb kauj vab thiab maus taus, xa lub zog ntawm cov pedals mus rau lub log.
Cov tshuab siv hauv kev lag luam: Hauv kev lag luam xws li textiles, ntim khoom, thiab luam ntawv, cov saw hlau siv los tsav ntau yam khoom siv kho tshuab kom ua tiav kev txav mus los sib xws.
Cov tshuab ua liaj ua teb: Hauv cov tshuab ua liaj ua teb xws li cov tshuab sau qoob loo thiab cov tsheb laij teb, cov saw hlau siv los xa hluav taws xob thiab txhim kho kev ua haujlwm zoo.
Kev txij nkawm thiab kev daws teeb meem ntawm cov saw hlau
Txawm hais tias cov saw hlau roller paub txog lawv qhov ruaj khov, kev saib xyuas kom zoo tseem ceeb heev. Nov yog qee cov kauj ruam yooj yim ntawm kev saib xyuas:
Kev tshuaj xyuas tsis tu ncua: Xyuas seb cov saw hlau puas muaj cov cim qhia tias hnav, ncab, lossis puas tsuaj.
Kev Ntxuav: Ntxuav cov saw hlau tsis tu ncua kom tshem tawm cov hmoov av thiab roj kom txo qhov hnav.
Kev Siv Lubrication: Siv cov roj saw hlau kom zoo los txo qhov kev sib txhuam thiab tiv thaiv xeb.
Kev kho qhov nruj: Tswj qhov nruj kom zoo. Yog xoob dhau los yog nruj dhau yuav cuam tshuam rau lub neej thiab kev ua haujlwm ntawm cov saw hlau.
Thaum lub saw hlau tsis ua haujlwm, cov teeb meem feem ntau suav nrog:
Kev hnav cov saw hlau: Kev hnav ntau dhau ntawm cov saw hlau tuaj yeem ua rau cov saw hlau tawg.
Kev ncab cov saw: Kev siv mus sij hawm ntev yuav maj mam ncab cov saw thiab cuam tshuam rau qhov kev sib txuas.
Kev puas tsuaj ntawm cov menyuam: Kev puas tsuaj ntawm cov menyuam yuav ua rau lub zog xa hluav taws xob tsis du.
Rau cov teeb meem no, kev hloov pauv thiab kev kho kom raws sijhawm yog qhov tsim nyog.
Cov qauv kev loj hlob yav tom ntej ntawm cov saw hlau
Nrog rau kev nce qib ntawm thev naus laus zis, cov saw hlau kuj tseem niaj hnub txhim kho. Nov yog qee qhov kev loj hlob yav tom ntej:
Kev tsim kho tshiab ntawm cov khoom siv: Kev siv cov khoom siv tshiab, xws li cov yas muaj zog thiab cov khoom sib xyaw, yuav ua rau cov saw hlau sib dua thiab ruaj khov dua.
Kev Txawj Ntse: Cov saw hlau uas muaj cov sensors sib xyaw ua ke tuaj yeem saib xyuas lawv qhov xwm txheej hauv lub sijhawm tiag tiag thiab kwv yees qhov xav tau kev saib xyuas.
Kev tsim qauv zoo rau ib puag ncig: Cov ntaub ntawv rov ua dua tshiab thiab kev siv hluav taws xob tsawg yuav ua rau cov saw hlau zoo rau ib puag ncig.
Kev Kho Kom Haum: Nrog rau kev txhim kho ntawm 3D printing technology, cov chains roller customized yuav ua tau kom tau raws li qhov xav tau ntawm cov ntawv thov tshwj xeeb.
