Cov kev cai tshwj xeeb rau cov saw hlau hauv cov khoom siv kho mob
Cov saw hlau siv ntau zuj zus hauv cov khoom siv kho mob, tshwj xeeb tshaj yog cov khoom siv uas muaj qhov tseeb siab thiab qhov xav tau kev ntseeg siab xws li cov neeg hlau phais thiab cov cuab yeej kuaj mob. Cov ntawv thov no muab cov kev cai tshwj xeeb rau kev ua haujlwm thiab qhov zoo ntawm cov saw hlau kom ntseeg tau tias cov khoom siv ua haujlwm ruaj khov thiab kev nyab xeeb ntawm cov neeg mob. Tsab xov xwm no yuav qhia meej txog cov kev cai tshwj xeeb rau cov saw hlau hauv cov khoom siv kho mob thiab tshawb nrhiav yuav ua li cas kom ua tau raws li cov kev cai no.

1. Kev xaiv khoom siv

1. Cov ntaub ntawv muaj zog thiab tiv taus corrosion
Cov saw hlau hauv cov khoom siv kho mob yuav tsum ua haujlwm hauv qhov chaw huv thiab huv si, yog li kev xaiv cov ntaub ntawv yog qhov tseem ceeb heev. Cov ntaub ntawv siv feem ntau suav nrog:
Hlau tsis xeb: muaj kev tiv thaiv corrosion zoo thiab biocompatibility, tsim nyog rau cov chaw uas xav tau kev tua kab mob ntau zaus hauv cov khoom siv kho mob.
Cov hlau sib xyaw: lub zog siab thiab kev hnav tsis kam siab, tsim nyog rau kev thauj khoom siab thiab kev xa mus rau qhov tseeb.

2. Kev kho qhov chaw
Yuav kom txhim kho qhov hnav tsis kam thiab corrosion tsis kam ntawm cov saw hlau, kev kho saum npoo tshwj xeeb feem ntau yuav tsum tau ua:
Carburizing thiab quenching: txhim kho qhov nyuaj ntawm cov menyuam thiab cov koob thiab txhim kho kev hnav tsis kam.
Kev kho plating: xws li nickel plating lossis chrome plating, ntxiv txhim kho kev tiv thaiv corrosion.

2. Kev tsim khoom raug
1. Qhov tseeb ntawm qhov ntev
Qhov tseeb ntawm cov saw hlau dov ncaj qha cuam tshuam rau nws qhov kev ua tau zoo thiab kev ntseeg tau ntawm kev sib kis. Cov saw hlau dov uas muaj qhov tseeb siab tuaj yeem txo qhov yuam kev ntawm kev sib kis thiab txhim kho qhov tseeb ntawm kev ua haujlwm ntawm cov khoom siv. Cov kev cai tshwj xeeb suav nrog:

Lub suab ntawm cov saw hlau: Qhov kev kam rau siab ntawm lub suab ntawm cov saw hlau yuav tsum tau tswj hwm nruj me ntsis hauv qhov ntau yam uas tau teev tseg kom ntseeg tau tias qhov sib xws thiab sib xws ntawm cov saw hlau.

Txoj kab uas hla ntawm lub log: Txoj kab uas hla ntawm lub log yuav tsum tsawg dua lossis sib npaug li ib nrab ntawm qhov sib txawv ntawm cov saw hlau kom ntseeg tau tias muaj kev sib cuag zoo thiab kev sib kis tau zoo.

2. Qhov tseeb ntawm cov hniav
Qhov tseeb ntawm cov hniav ntawm lub sprocket yog qhov tseem ceeb rau kev ua haujlwm ntawm txoj hlua khi. Cov hniav profile siab tuaj yeem txo qhov hnav thiab suab nrov ntawm cov saw thiab txhim kho kev ua haujlwm ntawm kev sib kis. Cov kev cai tshwj xeeb suav nrog:
Qhov tseeb ntawm cov hniav profile: Cov hniav profile yuav tsum ua tau raws li cov qauv kev cai kom ntseeg tau tias muaj kev sib txuas zoo ntawm cov saw thiab lub sprocket.
Kev xaiv tus lej hniav: Nws raug pom zoo kom siv lub sprocket nrog tsawg kawg 17 hniav, thiab lub sprocket nrog tsawg kawg 21 hniav yuav tsum tau siv nyob rau hauv qhov ceev ceev thiab cov xwm txheej thauj khoom siab.

3. Kev siv roj thiab kev txij nkawm

1. Cov kev cai rau lubrication
Cov saw hlau hauv cov khoom siv kho mob yuav tsum ua haujlwm hauv qhov chaw huv si thiab huv si, yog li kev xaiv thiab siv cov roj nplua nyeem yog qhov tseem ceeb heev:
Cov roj nplua nyeem uas tsis muaj kab mob: Siv cov roj nplua nyeem uas tsis muaj kab mob uas ua tau raws li cov qauv kho mob kom ntseeg tau tias tsis muaj kev ua qias tuaj rau cov khoom siv thiab cov neeg mob.
Kev siv roj nplua nyeem tas li: Xyuas thiab ntxiv cov roj nplua nyeem tas li kom ntseeg tau tias cov saw hlau tau siv roj nplua nyeem zoo thiab txo qhov hnav.
2. Cov kev cai txij nkawm
Kev saib xyuas tsis tu ncua yog qhov tseem ceeb kom ntseeg tau tias txoj saw hlau ua haujlwm tau ntev thiab ruaj khov:
Kev tshuaj xyuas tsis tu ncua: Xyuas seb cov saw hlau puas nruj, puas hnav thiab puas muaj roj nplua nyeem, thiab kho thiab hloov cov khoom uas puas hnyav raws sijhawm.
Kev Ntxuav thiab tua kab mob: Ntxuav thiab tua kab mob ntawm cov saw hlau tsis tu ncua kom ntseeg tau tias nws ua haujlwm hauv ib puag ncig huv.

4. Kev teeb tsa thiab kev sib dhos

1. Kev teeb tsa raug
Qhov tseeb ntawm kev teeb tsa ntawm cov saw hlau ncaj qha cuam tshuam rau nws qhov kev ua tau zoo thiab lub neej ntawm kev sib kis:
Kev hloov pauv axial: Qhov kev hloov pauv axial yuav tsum tau tswj hwm hauv 0.2-0.5 hli kom ntseeg tau tias kev ua haujlwm du ntawm cov saw hlau.
Kev sib dhos ntawm Sprocket: Cov sprocket yuav tsum tau sib dhos thiab cov shafts yuav tsum sib luag kom txo tau qhov yuam kev ntawm kev sib kis thiab kev hnav.
2. Kev hloov kho qhov nruj
Kev nruj kom haum tuaj yeem ua kom muaj kev ruaj khov thiab lub neej ntawm cov saw hlau:
Kev nruj: Qhov sag ntawm cov saw hlau yuav tsum yog 1% - 2% ntawm lub log kom ntseeg tau tias cov saw hlau tsis xoob lossis ntev dhau thaum lub sijhawm ua haujlwm.
Lub Tensioner: Thaum lub sijhawm ua haujlwm, cov saw hlau yuav ntev vim yog hnav, thiab yuav tsum muaj lub tensioner saw hlau kom tswj tau qhov nruj kom haum.

V. Cov kev cai ua tau zoo

1. Kev sib kis tau zoo heev
Cov saw hlau hauv cov khoom siv kho mob xav tau kev sib kis siab kom ntseeg tau tias cov khoom siv ua haujlwm tau zoo:
Kev ua haujlwm zoo ntawm kev sib kis: Nyob rau hauv kev lubrication zoo thiab kev ua haujlwm ib txwm muaj, kev ua haujlwm ntawm cov saw hlau tuaj yeem ncav cuag li 98%.
Qhov piv ntawm kev sib kis: Qhov piv ntawm kev sib kis ntawm txhua theem ntawm cov saw hlau feem ntau tuaj yeem ncav cuag 4: 1 (qhov siab tshaj plaws tsis pub tshaj 7: 1), thiab qhov piv ntawm kev sib kis tuaj yeem hloov pauv los ntawm kev hloov lub sprocket thaum tswj lub log.

2. Kev ntseeg siab siab
Cov saw hlau rau cov menyuam xav tau kev ntseeg siab hauv cov khoom siv kho mob kom ntseeg tau tias cov khoom siv ua haujlwm ruaj khov:
Lub zog tensile: Cov saw hlau yuav tsum dhau qhov kev sim lub zog tensile kom ntseeg tau tias nws yuav tsis tawg thaum muaj kev thauj khoom ntau.
Kev cuam tshuam: Nyob rau hauv qhov xwm txheej ntawm kev pib thiab nres ntau zaus, cov saw hlau yuav tsum tiv taus qhov kev cuam tshuam loj heev, thiab cov saw hlau uas tau dhau los ntawm ntau qhov kev sim kev puas tsuaj yuav tsum tau xaiv.

VI. Cov ntaub ntawv siv tau tiag tiag

1. Cov neeg hlau phais
Cov neeg hlau phais muaj qhov yuav tsum tau ua kom raug thiab ntseeg tau ntawm cov saw hlau dov. Cov saw hlau dov yog siv los tsav cov pob qij txha thiab cov cuab yeej ntawm tus neeg hlau thiab yuav tsum ua haujlwm ruaj khov hauv qab qhov raug siab thiab lub nra hnyav. Piv txwv li, cov saw hlau dov siv hauv tus neeg hlau phais yog ua los ntawm cov hlau tsis xeb muaj zog, uas tau carburized thiab quenched kom ntseeg tau tias muaj kev tiv taus hnav thiab lub zog tensile siab.

2. Cov khoom siv kuaj mob
Cov saw hlau hauv cov khoom siv kuaj mob siv los tsav kev txav mus los thiab kev tso chaw ntawm cov khoom siv thiab yuav tsum ua haujlwm raws li qhov tseeb siab thiab suab nrov tsawg. Piv txwv li, cov saw hlau siv hauv cov khoom siv kuaj mob siv cov sprockets thiab rollers uas muaj qhov tseeb siab kom ntseeg tau tias qhov kev sib kis du thiab raug.

VII. Xaus Lus
Kev siv cov saw hlau rau hauv cov khoom siv kho mob yuav tsum ua kom tau raws li qhov xav tau tshwj xeeb ntawm kev ua haujlwm siab, kev ntseeg siab siab thiab kev tiv taus corrosion siab. Los ntawm kev xaiv cov ntaub ntawv zoo, tsim cov sprockets thiab rollers uas muaj qhov tseeb siab, siv cov roj nplua nyeem tsis muaj kab mob, kev saib xyuas tsis tu ncua thiab kho qhov nro, koj tuaj yeem ua kom cov saw hlau ua haujlwm ruaj khov hauv cov khoom siv kho mob. Kuv vam tias tsab xov xwm no yuav pab koj nkag siab txog cov kev xav tau tshwj xeeb ntawm cov saw hlau rau hauv cov khoom siv kho mob.
