1. Cov Cheebtsam Hauv Qab Uas Muaj Kev Ntsuas Zoo: Komatsu Pem Hauv Ntej Idler Log Sib Dhos rau PC390-8, PC400 thiab PC450 Series

Cov Komatsu PC390-8, PC400 thiab PC450 series crawler excavators sawv cev rau lub hauv paus ntawm kev ua haujlwm nruab nrab mus rau loj, kev khawb av thiab kev khawb av thoob ntiaj teb. Cov hydraulic excavators hnyav no, tsim los ntawm Komatsu Ltd.—lub ntiaj teb thib ob loj tshaj plaws tsim khoom siv hauv kev tsim kho, kev khawb av thiab cov khoom siv hluav taws xob, nrog rau keeb kwm txij li xyoo 1921 thiab kev ua haujlwm hla ntau dua 150 lub tebchaws—yog tsim los rau kev khawb av ntau, kev tuav pob zeb, kev khawb av loj thiab cov haujlwm tsim kho vaj tse uas xav tau ntau.

Lub PC390LC-8M0 variant, tsim tawm txij li xyoo 2022, hnyav kwv yees li 38,000–41,023 kg (39–40 tuj chav kawm) nrog txoj kab dav ntawm 700 mm, ua rau nws haum rau cov xwm txheej hnyav, kev khawb pob zeb thiab kev ua haujlwm hauv qhov chaw khawb av. Cov koob PC400 (PC400-6, PC400-7, PC400-8 thiab PC400LC variants) nyob hauv qib 40-tuj, nruab nrog Komatsu's advanced closed-load sensing hydraulic system (CLSS) thiab lub cav xa kwv yees li 187 kW (254 PS) ntawm lub zog net flywheel. Cov koob PC450 (PC450-7, PC450-8 thiab PC450LC variants) yog lub tshuab khawb av hydraulic hnyav tsim rau kev tsiv av loj, kev khawb pob zeb thiab kev tsim kho, muaj lub hauv qab txhim khu kev qha thiab kev sib txuas dav dav uas ua rau muaj kev khawb thiab kev thauj khoom zoo.

1.1 Lub Luag Haujlwm Tseem Ceeb ntawm Lub Rooj Sib Tham Pem Hauv Ntej Idler

Nyob rau ntawm pem hauv ntej ntawm txoj kab sib tw uas nyob ib sab ntawm lub sprocket tsav, lubTaug qab pem hauv ntej Idler log sib dhosyog ib qho ntawm cov khoom tseem ceeb tshaj plaws hauv kab pem hauv ntej hauv txhua lub crawler excavator lub undercarriage system. Tsis zoo li cov menyuam nqa khoom thiab cov menyuam hauv qab, uas txhawb nqa cov saw hlau tawm tsam lub thav duab ntawm txoj kev, lub idler pem hauv ntej ua haujlwm peb txoj haujlwm sib txawv:

• Kev Taw Qhia thiab Kev Sib Tov ntawm Cov Hlau Khiav: Ob lub flanges uas tau ua kom raug ntawm lub idler tiv thaiv kev poob ntawm txoj kev, ua kom cov hlau khiav sib txuas nrog lub sprocket thiab lub thav duab hauv qab thaum lub sijhawm tig, kev ua haujlwm ntawm sab thiab kev mus ncig hla thaj av tsis sib luag.
• Kev Nqus Tau Lub Zog Thiab Kev Cuam Tshuam: Raws li cov khoom tseem ceeb uas ntsib cov teeb meem, cov pob zeb tawg thiab cov av tsis sib xws ua ntej, lub idler pem hauv ntej yuav tsum nqus thiab tshem tawm cov khoom cuam tshuam ncaj qha, tiv thaiv cov saw hlau, cov menyuam hauv qab thiab tag nrho cov kab ke hauv qab los ntawm kev hnav ua ntej lossis kev puas tsuaj ntawm cov qauv.
• Kev Sib Koom Tes Nrog Hydraulic Track Tensioning System: Lub idler sib dhos sib txuas ncaj qha nrog lub tog raj kheej kho txoj kev (tensioner) ntawm lub yoke lossis lub thaiv qhia. Qhov sib txuas no tso cai rau kev kho qhov nruj ntawm txoj kev kom raug, them rau kev nthuav dav ntawm txoj kev saw hlau vim kev hnav thiab ua kom txoj kev sag zoo tshaj plaws nyob rau hauv ntau yam kev thauj khoom thiab thaj chaw. Txoj kev uas xoob dhau yuav pov lossis poob thaum lub sijhawm tig ceev ceev, thaum txoj kev uas nruj dhau yuav tsim kev thauj khoom ntau dhau rau cov motors thiab bearings.

Nyob rau hauv cov ntawv thov uas muaj kev cuam tshuam loj xws li kev khawb pob zeb, kev thauj khoom hauv chaw txua zeb lossis kev tshem tawm cov khoom siv hauv kev khawb av, lub idler pem hauv ntej raug kev cuam tshuam tas li, kev yaig av nkos, kev nqus dej thiab kev hloov pauv kev ntxhov siab. Yog li ntawd, lub idler hloov pauv zoo, qib kev khawb av yuav tsum tau tsim nrog kev tsim kho hlau uas raug tsim los yog tsim, cov txheej txheem sib khi ntau theem siab heev thiab cov nplaim hnav uas tau ua los ntawm induction-hardened.

1.2 Cov lej sib txuas lus rau Komatsu PC390-8 / PC400 / PC450 Series

Plaub tus lej OEM hauv qab no sawv cev rau lub rooj sib txoos pem hauv ntej ntawm Komatsu rau PC390-8, PC400 thiab PC450 series. Txhua tus lej sib raug rau ib qho version tshwj xeeb, hom chassis (tus qauv, hnyav-duty lossis ntev-track) thiab tiam:

Ntawm cov no, tus lej ntawm ib feem2083000201,2083000300thiab2083000013feem ntau yog txuam nrog PC400-6, PC450-6, PC400-7, PC450-7 thiab PC390-8 series. Tus lej cross-reference KM1973—uas sib raug rau 208-30-00200 (ib qho kev sib dhos idler ze rau PC400-5 thiab PC400 qauv)—kuj tseem siv sib pauv rau ntau daim ntawv thov no, nrog rau cov npe lag luam lees paub KM1973 ua tus lej pab pawg idler cuam tshuam rau PC400-5, PC400, PC400-6 thiab PC450 series. Ib yam li ntawd, tus lej 208-30-00200 tau sau tseg rau Komatsu PC400-5 thiab PC400 idler pab pawg.

Tus lej ntawm qhov2083000070yog hais txog tshwj xeeb rau Komatsu PC400LC-3, PC400-3 thiab PC400-1 excavators, ua rau nws tshwj xeeb tshaj yog rau cov neeg teb xov tooj uas khiav cov tshuab PC400 tiam qub thaum tswj kev sib raug zoo nrog PC400-5, PC400-6 thiab PC400-7 chassis tom qab.

Kev nkag siab txog qhov sib txawv ntawm cov lej no yog qhov tseem ceeb rau cov tswv tsheb thiab cov pab pawg yuav khoom, vim tias kev teeb tsa lub rooj sib dhos idler tsis raug tuaj yeem ua rau txoj kev sib dhos tsis raug, hnav sai dua ntawm lub sprocket thiab txoj kev sib tw, txo qis lub neej hauv qab thiab muaj peev xwm ua rau txoj kev sib tsoo thaum lub sijhawm ua haujlwm.
