Hauv kev ua haujlwm zoo, siv txoj hauv kev kom raug tuaj yeem txo cov saw hlau puas. Rau cov saw hlau siv rau kev sib kis lossis kev thauj khoom -cov kabmob uas yuav tsum tau ua haujlwm ua ke nrog sprockets, nws yog ib qho tseem ceeb uas yuav tsum tau xyuas seb cov saw hlau puas sib tw ua ntej pib cov khoom siv. Ib txoj hlua twisted yuav tsis tsuas yog daig thiab sib txhuam nrog sprockets, ua kom nrawm nrawm ntawm ob qho tib si, tab sis kuj tuaj yeem ua rau lub zog tsis sib xws, ua rau muaj kev ntxhov siab hauv zos thiab cov kab nrib pleb. Lub caij no, nws yog ib qho tsim nyog yuav tsum nruj me ntsis xaiv chains ntawm kev sib piv specifications raws li cov cuab yeej siv phau ntawv, thiab nco ntsoov tias muaj qhov sib txawv tseem ceeb ntawm cov ntsug load peev thiab lub kaum sab xis load peev xwm ntawm chains ntawm tib specification - thaum cov saw siv ntawm lub kaum sab xis, nws load- bearing peev yuav maj mam txo thaum lub kaum sab xis nce. Tsis quav ntsej tus cwj pwm no yuav ua rau muaj kev sib txuas ntau dhau.
Overloading tsis yog tsuas yog ib qho tseem ceeb ntawm kev nyab xeeb kev nyab xeeb tab sis kuj ncaj qha ua rau cov saw hlau deformation thiab tawg, ua rau nws lub neej ua haujlwm luv. Kev tshuaj xyuas tsis tu ncua thiab kev saib xyuas kev tshaj lij yog qhov tseem ceeb txuas rau kev txuas lub neej ntawm cov saw hlau. Nws raug nquahu kom tsim kom muaj kev tshuaj xyuas tsis tu ncua. Ua ntej, thaum lub sij hawm, thiab tom qab txhua qhov kev siv, tsom rau kev tshuaj xyuas cov saw hlau rau kev puas tsuaj ntawm qhov chaw, hnav, tawg, deformation, thiab lwm yam teeb meem, thaum tseem tshuaj xyuas seb cov saw hlau puas tsim nyog. Tej yam txawv txav uas pom yuav tsum tau kho tam sim ntawd. Nyob rau hauv cov nqe lus ntawm kev txij nkawm, nws yog ib qho tsim nyog yuav tau xaiv cov khoom tsim nyog los tiv thaiv- xeb lubricating roj raws li kev khiav hauj lwm ib puag ncig thiab chain condition, thiab tsis tu ncua lubricate cov saw. Qhov no tsis tsuas yog tsim cov yeeb yaj kiab tiv thaiv ntawm cov saw hlau kom cais cov huab cua thiab noo noo, ua tiav cov teebmeem tiv thaiv- xeb, tab sis kuj txo qis kev sib txhuam ntawm cov saw thiab sprockets, ua kom muaj kev ua haujlwm zoo dua.
