Nkag siab qhov tseem ceeb ntawm Cov Menyuam Chain Fatigue Standards: 50, 60 thiab 80 Dhau

Rau kev lag luam tshuab thiab khoom siv, cov menyuam chains ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm kom du thiab ua haujlwm tau zoo. Cov chains no muaj ntau yam kev siv, los ntawm cov tshuab conveyor mus rau cov tshuab ua liaj ua teb, thiab tau tsim los tiv thaiv kev ntxhov siab thiab qaug zog. Txhawm rau kom ntseeg tau tias muaj kev ntseeg siab thiab ua haujlwm ntev ntawm cov menyuam chains, ntau yam qauv thiab cov kev qhia tshwj xeeb tau tsim los sim lawv cov kev ua tau zoo nyob rau hauv cov xwm txheej sib txawv. Nyob rau hauv no blog, peb yuav delve rau hauv qhov tseem ceeb ntawm cov menyuam saw qaug zog cov qauv, tsom tshwj xeeb rau cov dhau 50, 60 thiab 80 tus qauv, thiab vim li cas lawv tseem ceeb heev kom ntseeg tau qhov zoo thiab kev ntseeg siab ntawm cov menyuam chains.

Cov menyuam chains raug rau ntau yam dynamic loads thiab kev ua haujlwm uas, yog tias tsis tsim thiab tsim kom zoo, tuaj yeem ua rau qaug zog thiab ua tsis tiav. Qhov no yog qhov uas cov qauv kev qaug zog tuaj rau hauv kev ua si, raws li lawv muab cov txheej txheem ntawm cov txheej txheem thiab cov qauv rau kev ntsuas qhov qaug zog ntawm cov menyuam chains. Cov qauv 50, 60 thiab 80 dhau los qhia tias cov saw hlau muaj peev xwm tiv taus ib theem ntawm kev qaug zog, nrog cov lej siab dua qhia tias muaj kev qaug zog ntau dua.

Cov txheej txheem rau kev dhau 50, 60 thiab 80 yog nyob ntawm tus naj npawb ntawm cov voj voog uas cov hlua khi tuaj yeem tiv taus ua ntej ua tsis tiav ntawm qhov teev thiab nrawm. Piv txwv li, cov saw hlau uas hla 50 ntsuas tuaj yeem tiv taus 50,000 lub voj voog ua ntej tsis ua haujlwm, thaum cov saw hlau hla 80 ntsuas tuaj yeem tiv taus 80,000 cycles. Cov qauv no yog ib qho tseem ceeb los xyuas kom meej tias cov menyuam chains ua tau raws li lawv cov kev xav tau ntawm daim ntawv thov, txawm nyob rau hauv cov khoom siv hnyav lossis cov khoom siv precision.

Ib qho ntawm cov ntsiab lus tseem ceeb uas cuam tshuam rau qhov qaug zog ntawm cov saw hlau yog qhov zoo ntawm cov ntaub ntawv thiab cov txheej txheem tsim khoom siv hauv nws cov khoom. Chains uas dhau 50, 60 thiab 80 tus qauv feem ntau yog ua los ntawm cov hlau zoo hlau thiab tau dhau los ua cov txheej txheem tsim khoom kom ntseeg tau tias muaj kev sib haum xeeb thiab lub zog. Qhov no tsis tsuas yog txhim kho lawv txoj kev qaug zog, tab sis kuj tseem pab txhim kho lawv txoj kev ntseeg tau thiab kev pab lub neej.

Ntxiv rau cov khoom siv thiab cov txheej txheem tsim khoom, cov menyuam saw tsim thiab engineering ua lub luag haujlwm tseem ceeb hauv kev ua kom tau raws li 50, 60 thiab 80 tus qauv dhau. Cov yam ntxwv xws li cov duab thiab contour ntawm cov khoom sib txuas thiab kev sib dhos yog qhov tseem ceeb hauv kev txiav txim siab qaug zog ntawm cov saw hlau. Cov tuam txhab lag luam nqis peev hauv kev tsim qauv thiab simulation cov cuab yeej los ua kom zoo rau cov menyuam saw kev ua tau zoo thiab xyuas kom lawv ua tau raws lossis dhau cov qauv kev qaug zog.

Kev ua raws li cov qauv kev qaug zog yog qhov tseem ceeb tsis yog rau kev ua tau zoo thiab kev ntseeg siab ntawm cov hlua khi, tab sis kuj rau kev nyab xeeb ntawm cov khoom siv thiab cov neeg ua haujlwm. Chains uas ua tsis tau ntxov ntxov vim qaug zog tuaj yeem ua rau lub sijhawm poob qis, kev kho kim thiab muaj peev xwm muaj kev nyab xeeb. Los ntawm kev ua kom cov menyuam chains ua tau raws li 50, 60 thiab 80 dhau cov qauv, cov neeg tsim khoom thiab cov neeg siv kawg tuaj yeem muaj kev ntseeg siab rau kev ua haujlwm ntev thiab kev ua haujlwm ntawm cov saw hlau, thaum kawg ua kom muaj txiaj ntsig thiab ua haujlwm tau zoo.

Tsis tas li ntawd, kev ua raws li cov qauv kev qaug zog qhia tau hais tias tus neeg tsim khoom tau cog lus rau qhov zoo thiab kev ua tau zoo ntawm lawv cov khoom. Los ntawm kev muab cov hlua khi rau kev sim ua rau qaug zog thiab ua tau raws li 50, 60 thiab 80 dhau cov qauv, cov tuam txhab ua qauv qhia lawv txoj kev cog lus los muab cov neeg siv khoom txhim khu kev qha thiab cov khoom ua tau zoo. Tsis tsuas yog qhov no nce kev ntseeg siab thiab kev ntseeg siab ntawm lub hom, nws tseem pab txhim kho cov chaw tsim khoom lub koob npe nrov thiab kev ntseeg siab hauv kev lag luam.

Hauv cov ntsiab lus, kev pom zoo 50, 60 thiab 80 cov qauv kev qaug zog ua lub luag haujlwm tseem ceeb hauv kev ua kom zoo, kev ntseeg tau thiab kev ua tau zoo ntawm cov menyuam chains hauv ntau daim ntawv thov kev lag luam. Cov qauv no yog cov qauv ntsuas rau kev ntsuas kev qaug zog ntawm cov menyuam cov hlua, thiab kev ua raws cai qhia cov saw hlau muaj peev xwm tiv taus qee qhov kev ntxhov siab thiab qaug zog. Los ntawm kev ua tau raws li cov qauv no, cov tuam ntxhab tuaj yeem ua pov thawj lawv txoj kev mob siab rau kev xa cov khoom zoo, thaum cov neeg siv kawg tuaj yeem muaj kev ntseeg siab nyob rau hauv kev ua haujlwm ntev thiab kev nyab xeeb ntawm cov menyuam chains lawv txoj haujlwm cia siab rau. Raws li thev naus laus zis thiab cov ntaub ntawv txuas ntxiv mus, cov tuam ntxhab yuav tsum ua raws li cov qauv tshiab thiab kev tsim kho tshiab los txhim kho kev qaug zog thiab kev ua tau zoo tag nrho ntawm cov menyuam chains, thaum kawg ua rau muaj txiaj ntsig zoo thiab txhim khu kev lag luam ib puag ncig.
