Roller chains ua lub luag haujlwm tseem ceeb hauv ntau yam kev lag luam xws li kev tsim khoom, tsheb, thiab kev ua liaj ua teb, qhov chaw uas lawv tau siv los xa cov hluav taws xob zoo.Txawm li cas los xij, ib qho kev txhawj xeeb ntawm cov neeg siv yog cov hlua khi hlua khi rau lub sijhawm.Peb feem ntau hnov cov lus nug: "Yuav ua li cas cov menyuam chains tsis ncab?"Nyob rau hauv no blog, peb mam li delve rau hauv lub ncauj lus no, debunk ib co myths xwb, thiab nthuav tawm qhov tseeb qab qhov tshwm sim ntawm stretching.
Kawm paub txog cov menyuam saw stretching:
Yuav kom nkag siab tiag tiag lub tswv yim ntawm cov menyuam saw stretching, nws yog ib qho tseem ceeb kom nkag siab tias cov menyuam chains ua haujlwm li cas.Cov menyuam chains muaj cov kev sib txuas sib txuas, txhua qhov txuas uas muaj ob sab hauv thiab sab nrauv, pins, rollers thiab bushings.Thaum siv fais fab, cov chais ua rau cov hniav ntawm lub sprocket, ua rau cov kev sib txuas ntawm cov saw hlau rau articulate nyob ib ncig ntawm lub voj voog ntawm sprocket.Nyob rau tib lub sijhawm, cov menyuam saw elongation, feem ntau hu ua stretching, tuaj yeem tshwm sim vim qhov sib cuam tshuam ntawm cov menyuam thiab cov hniav sprocket.
Lus dab neeg: Roller chain stretching never stops:
Nws feem ntau ntseeg hais tias ib zaug ib tug menyuam saw pib ncab, nws yuav nyob mus ib txhis.Txawm li cas los xij, qhov no yog qhov tsis to taub.Lub elongation ntawm ib tug menyuam saw feem ntau tsis yog infinite thiab yuav ncav cuag ib tug point uas nws tsis ncab.Lub stretch ntawm ib tug saw yog feem ntau cuam tshuam los ntawm tej yam xws li thawj zaug nro, load, ib puag ncig tej yam kev mob, lubrication thiab txij nkawm kev coj.
Yam Tseem Ceeb Ntawm Cov Menyuam Chain Stretch:
1. Initial Tension: Thawj qhov nro uas siv thaum lub sijhawm teeb tsa ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab ceev cov saw yuav ncab npaum li cas.Ib txoj hlua tensioned zoo, nyob rau hauv cov chaw tsim tshuaj paus qhov kev pom zoo tolerances, yuav muaj tsawg stretch tshaj ib tug under-tensioned los yog over-tensioned saw.
2. Chaw thau khoom tej yam kev mob: Qhov loj thiab qhov xwm txheej ntawm cov khoom siv rau cov saw hlau yuav ua rau kom ncav sijhawm.Kev thauj khoom siab dua thiab kev cuam tshuam sai sai ua rau cov txheej txheem hnav thiab ua rau kom muaj elongation.
3. Ib puag ncig tej yam kev mob: hnyav ib puag ncig, xws li kub kub, corrosive chemicals los yog abrasive hais, yuav ua rau kom cov saw hnav thiab ncab.Kev tu thiab lubrication tsis tu ncua tuaj yeem pab txo cov teebmeem no.
4. Lubrication: lubrication kom zoo yog qhov tseem ceeb los txo kev sib txhuam thiab hnav hauv cov khoom siv saw.Cov saw hlau zoo-lubricated tau ntsib tsawg dua vim tias cov roj nplua nyeem tsim cov txheej txheem tiv thaiv uas txo qis hnav.
Kev ceev faj kom txo qis stretching:
Thaum nws tsis tuaj yeem tshem tawm tag nrho cov hlua hlua khi, cov kauj ruam tiv thaiv tuaj yeem ua kom txo qis nws cov teebmeem:
1. Kev tu tsis tu ncua: Ua raws li kev saib xyuas zoo, suav nrog kev tu, tshuaj xyuas thiab lubrication, yuav pab txheeb xyuas cov saw hlau uas muaj peev xwm hnav thiab hais txog nws ua ntej nws yuav ua rau ntau dhau.
2. Kev Ruaj Ntseg Zoo: Ua kom cov saw hlau raug teeb tsa nrog qhov tseeb pib nruj, uas yog nyob rau hauv cov chaw tsim tshuaj paus kev pom zoo, yuav pab kom nws lub neej ntev thiab txo qhov ncab.
3. Lubrication: Siv lub lubricant kom raug ntawm lub sijhawm pom zoo yuav pab txo qis kev sib txhuam, dissipate tshav kub thiab txo qhov ncab ntawm hnav.
Nws yog ib txwm muaj rau cov menyuam chains kom ncab nrog kev siv tsis tu ncua thiab hnav.Txawm li cas los xij, tsis sib haum xeeb rau kev ntseeg nrov, cov menyuam chains ncav cuag qhov chaw nres.Los ntawm kev nkag siab txog cov kev cuam tshuam thiab kev ceev faj kom raug, cov neeg siv tuaj yeem txo qis thiab txhim kho kev ua haujlwm thiab kev pabcuam lub neej ntawm cov menyuam chains hauv lawv daim ntawv thov.
