Roller chains yog ib qho tseem ceeb ntawm ntau yam kev siv hauv kev lag luam, suav nrog kev tsim khoom, kev ua liaj ua teb thiab tsheb tshuab. Tsim los xa cov hluav taws xob zoo thiab kev ntseeg siab, cov saw hlau no yog qhov tseem ceeb rau kev ua haujlwm zoo ntawm cov khoom siv thiab tshuab. Txawm li cas los xij, txhawm rau ua kom nws lub neej ntev thiab kev ua tau zoo, cov hlua khi cov menyuam yuav tsum tau ua cov txheej txheem kev kho cua sov kom ua kom lawv cov kav ntev thiab lub zog.
Kev kho cua sov yog ib kauj ruam tseem ceeb hauv kev tsim cov menyuam cov saw hlau vim nws tuaj yeem txhim kho cov khoom siv ntawm cov menyuam saw zoo li nws hnav thiab qaug zog. Los ntawm kev xa cov saw hlau mus rau cov txheej txheem cua sov thiab cua txias, cov khoom siv microstructure tuaj yeem hloov tau los txhim kho hardness, toughness thiab tag nrho kev ua tau zoo. Tsab ntawv xov xwm no yuav ua tib zoo saib qhov tseem ceeb ntawm kev kho cua sov hauv kev ua kom cov saw hlau ntev ntev thiab ntau yam kev koom tes hauv cov txheej txheem.
Lub hom phiaj tseem ceeb ntawm cov menyuam saw kub kho yog kom ua tiav qhov zoo tshaj plaws sib npaug ntawm cov khoom hardness thiab toughness. Qhov no yog ua tiav los ntawm kev ua tib zoo tswj cov cua sov thiab cua txias uas tsim los hloov cov saw hlau microstructure ntawm qib atomic. Cov txheej txheem kev kho cua sov tshaj plaws rau cov menyuam chains muaj xws li quenching thiab tempering, carburizing thiab induction hardening.
quenching thiab tempering yog cov txheej txheem kev kho cua sov uas siv dav rau cov menyuam chains. Nws heats cov saw mus rau qhov kub thiab txias sai sai hauv qhov nruab nrab quenching xws li roj lossis dej. Qhov kev ua kom txias sai sai no tsim cov qauv tawv tawv uas ua rau cov tawv tawv thiab hnav tsis kam ntawm cov saw hlau. Cov saw hlau yog ces tempered los ntawm reheating nws mus rau ib tug qis kub, uas muab cov saw toughness thiab thiaj li nyob rau hauv kev nyuaj siab, yog li ua rau nws tag nrho durability.
Carburizing yog lwm txoj kev kho cua sov zoo rau cov menyuam chains, tshwj xeeb tshaj yog rau cov ntawv thov uas yuav tsum muaj qhov tawv tawv thiab hnav tsis kam. Thaum lub sij hawm cov txheej txheem carburizing, cov saw hlau raug rau cov pa roj carbon nplua nuj nyob rau hauv qhov kub thiab txias, tso cai rau cov pa roj carbon atoms mus rau hauv txheej txheej ntawm cov khoom. Qhov no ua rau lub plhaub tawv tawv nrog cov tub ntxhais tawv tawv, muab kev hnav zoo heev thiab qaug zog thaum tuav lub zog tag nrho ntawm cov saw hlau.
Induction hardening yog cov txheej txheem kev kho cua sov tshwj xeeb feem ntau siv los xaiv cov tawv tawv tshwj xeeb ntawm cov hlua khi, xws li cov khoom thauj khoom thiab cov ntsiab lus sib cuag. Nyob rau hauv cov txheej txheem no, high-frequency induction cua sov yog siv los ua kom sov lub hom phiaj cheeb tsam, uas yog ces quenched mus cuag lub siab xav hardness. Induction hardening tso cai rau kev tswj xyuas qhov tob ntawm quenching thiab txo qis deformation, ua rau nws zoo tagnrho rau kev txhim kho cov kav ntev ntawm cov khoom tseem ceeb hauv cov menyuam chains.
Ntxiv nrog rau cov txheej txheem kev kho cua sov no, kev xaiv cov khoom siv ua lub luag haujlwm tseem ceeb hauv kev ua kom cov menyuam saw ntev ntev. High-quality alloy steels, xws li 4140, 4340 thiab 8620, feem ntau yog siv los tsim cov menyuam chains vim lawv zoo heev hardenability thiab lub zog. Cov ntaub ntawv no zoo haum rau cov txheej txheem kho cua sov thiab muaj peev xwm ua tau raws li qhov xav tau ntawm cov khoom siv kho tshuab, uas yog qhov tseem ceeb rau kev tiv thaiv kev ua haujlwm hnyav uas tau ntsib los ntawm cov hlua khi.
Maximizing lub durability ntawm cov menyuam saw los ntawm kev kho cua sov tsis tsuas yog ncua nws cov kev pab cuam lub neej, tab sis kuj pab txhim kho tag nrho cov efficiency thiab kev cia siab ntawm cov machinery nws yog siv rau. Kev kho cua sov kom zoo rau cov menyuam chains muab kev hnav zoo dua, qaug zog thiab tiv thaiv corrosion, txo cov kev xav tau ntawm kev saib xyuas thiab kev poob qis thaum ua kom muaj kev ua tau zoo ib yam hauv kev xav tau kev lag luam ib puag ncig.
Hauv cov ntsiab lus, kev kho cua sov yog ib qho tseem ceeb hauv kev ua kom cov menyuam saw ntev ntev. Los ntawm kev muab cov saw hlau rau cov txheej txheem kev kho cua sov tshwj xeeb xws li tempering, carburizing, thiab induction quenching, cov khoom siv ntawm cov saw tuaj yeem txhim kho tau zoo, yog li txhim kho hardness, toughness, thiab hnav tsis kam. Ua ke nrog kev siv cov hlau alloy zoo, kev kho cua sov ua lub luag haujlwm tseem ceeb hauv kev ua kom lub neej kev pab cuam thiab kev ntseeg siab ntawm cov menyuam chains hauv ntau daim ntawv thov kev lag luam. Yog li ntawd, cov neeg tsim khoom thiab cov neeg siv khoom kawg yuav tsum tau ua qhov tseem ceeb ntawm kev siv cov kev kho cua sov kom tsim nyog kom ua tau zoo thiab ua haujlwm ntev ntawm cov hlua khi hauv lawv cov tshuab thiab khoom siv.
