9. Kev Teeb Tsa, Kev Txij Nkawm, thiab Kev Txhim Kho Lub Neej Kev Pabcuam
9.1 Kev Txheeb Xyuas Ua Ntej Kev Teeb Tsa
Ua ntej yuav txhim kho lub rooj sib dhos tshiab ntawm txoj kev khiav, xyuas kom meej cov kev ntsuas tseem ceeb hauv qab no:
- Kev sib xws ntawm cov qauv mounting — Paub meej tias qhov sib nrug ntawm lub qhov ntsia hlau (HL/HS) phim qhov loj ntawm lub bracket ncej: qhov sib nrug kab rov tav ntawm 286–290 hli, qhov sib nrug ntsug ntawm 64–65 hli, M16 bolts
- Txoj kab uas hla thiab dav ntawm lub log tsheb laij teb — Xyuas kom tseeb tias txoj kab uas hla tag nrho (DS) ntawm 481–500 hli thiab qhov dav ntawm lub log tsheb laij teb (WT) ntawm 156–160 hli phim qhov sib nrug ntawm txoj kab sib txuas ntawm txoj kev.
- Kev teeb tsa flange — Paub meej tias ob-flange tsim phim OEM specification
- Cov xwm txheej ntawm txoj saw hlau — Ntsuas qhov ntev ntawm txoj saw hlau; yog tias tshaj 3%, kev hloov txoj saw hlau yuav tsum ua ntej kev teeb tsa idler
- Lub tog raj kheej tensioner ntawm txoj kev - Tshawb xyuas seb puas muaj xeb, puas tsuaj, thiab ua haujlwm kom raug.
- Cov xwm txheej ntawm lub foob - Xyuas kom tseeb tias cov foob ntab thiab O-rings tau muab tso rau qhov chaw raug
9.2 Cov Txheej Txheem Txhim Kho
Raws li cov txheej txheem ntawm phau ntawv qhia Hitachi:
- Txhawb lub tshuab kom ruaj khov rau ntawm qhov chaw ruaj khov, tiaj tiaj nrog txoj saw hlau uas tsis muaj kev ntxhov siab.
- Tshem tawm cov idler assembly mounting bolts uas twb muaj lawm siv cov cuab yeej torque tsim nyog
- Ntxuav cov ntsia hlau thiab cov ntsia hlau uas rub lub cev; xyuas seb puas puas tsuaj lossis hnav.
- Tso lub rooj sib dhos pem hauv ntej tshiab thiab ntsia cov ntsia hlau tshiab uas muaj zog heev (kev siv cov ntsia hlau qub dua yog qhov txaus ntshai rau kev nyab xeeb)
- Cov ntsia hlau torque raws li qhov qhia tshwj xeeb (saib phau ntawv qhia Hitachi rau cov nqi tseeb)
- Siv roj los ntawm lubrication fitting rau pre-lubricate bearings thiab seals
- Kho qhov nro ntawm txoj kab kom raws li qhov chaw tsim khoom teev tseg siv lub tog raj kheej tensioner ntawm txoj kab
- Siv lub tshuab ntawm qhov ceev qis thiab tshuaj xyuas seb qhov kev sib hloov ntawm lub idler puas zoo, qhov kev sib khi ruaj khov, thiab kev sib dhos ntawm txoj kab
Qhov hnyav ntawm lub rooj sib dhos idler kwv yees li 70 kg (155 lb) xav tau cov khoom siv tsa kom zoo rau kev tuav pov hwm thaum lub sijhawm teeb tsa.
9.3 Lub Sijhawm Txij Nkawm
| Lub sijhawm luv | Kev Ua Haujlwm |
|---|---|
| Txhua 10 teev ua haujlwm (tej yam mob hnyav) | Tshuaj xyuas seb puas muaj roj xau, suab nrov tsis zoo, kev co, lossis cov ntsia hlau xoob |
| Txhua 50 teev ua haujlwm (tej yam xwm txheej ib txwm muaj) | Kev tshuaj xyuas pom ntawm cov khoom hauv qab ntawm lub tsheb thauj khoom |
| Txhua 250 teev ua haujlwm | Siv cov roj lubricating los ntawm kev siv cov roj sib xyaw |
| Txhua 500 teev ua haujlwm | Tshawb xyuas seb puas muaj cov bolts xoob; rov tig dua yog tias tsim nyog |
| Txhua 1,000 teev ua haujlwm | Tshawb xyuas qhov tob ntawm kev hnav ntawm lub log idler; piv rau cov kev txwv kev hnav (feem ntau yog 3–5 hli kev hnav uas tso cai) |
| Raws li qhov xav tau | Yog tias pom tias muaj kev ua si ntau dhau, kev xau ntawm lub foob, suab nrov ntawm lub bearing, lossis flange hnav, hloov lub idler sib dhos |
Kev ntxuav tas li ntawm thaj chaw hauv qab kom tshem tawm cov av thiab cov khib nyiab, ua raws li kev lubrication ntawm cov khoom uas xav tau lubrication, yog qhov tseem ceeb rau kev txo qis kev pheej hmoo ntawm kev tawg, txuas lub neej ntawm cov khoom hauv qab ntawm lub excavator, thiab tswj kev ua haujlwm zoo tshaj plaws ntawm cov khoom siv.
9.4 Hom Kev Ua Tsis Tau Zoo thiab Kev daws teeb meem
| Cov tsos mob | Tej zaum yuav muaj laj thawj | Kev Ua Haujlwm Pom Zoo |
|---|---|---|
| Cov roj xau los ntawm cov foob | Kev ua tsis tiav ntawm lub foob pob lossis kev hnav bushing | Hloov lub rooj sib dhos idler; xyuas seb txoj kab sib dhos zoo li cas |
| Suab nrov heev thaum lub sijhawm ua haujlwm | Kev hnav ntawm cov kabmob lossis kev puas tsuaj sab hauv | Tshem tawm thiab tshuaj xyuas; hloov qhov sib dhos yog tias puas lawm |
| Kev hnav tsis sib xws ntawm cov tread | Cov saw hlau tsis sib haum lossis cov sprockets / rollers hnav lawm | Tshawb xyuas qhov nruj thiab kev sib dhos ntawm txoj kab; hloov cov saw yog tias ntev dhau lawm |
| Kev qaug dab peg ntawm tus neeg tsav tsheb | Kev nkag mus rau hauv av lossis kev ua tsis tiav ntawm lub cev | Hloov lub rooj sib dhos idler tam sim ntawd kom tiv thaiv kev puas tsuaj ntawm txoj kev |
| Kev taug kev ntawm txoj kev sab nraud | Cov flanges idler uas hnav lawm lossis txoj kev tsis sib haum | Tshawb xyuas qhov dav ntawm flange; hloov lub idler yog tias flanges hnav lawm |
| Taug qab kev poob siab | Kev puas tsuaj ntawm lub cylinder tensioner lossis kev sib txuas ntawm lub idler carriage | Tshawb xyuas lub kaw lus tensioner; xyuas kom meej tias lub idler carriage swb mus dawb |
9.5 Kev Cia Siab Rau Lub Neej Ua Haujlwm
Nyob rau hauv kev tsim kho thiab kev ua pob zeb ib txwm muaj, lub tshuab ua haujlwm pem hauv ntej zoo uas ua tau raws li HRC 52–58 qhov nyuaj ntawm qhov chaw nrog qhov tob 4–8 hli tuaj yeem ua tiav 4,000–6,000 teev ua haujlwm ua ntej yuav tsum tau hloov. Hauv kev siv hnyav nrog cov ntaub ntawv abrasive heev (silica content > 30%) thiab kev ua haujlwm tas mus li, lub neej ua haujlwm yuav raug txo kom txog 3,000–4,000 teev.
Rau lub neej hauv qab ntawm lub tsheb thauj khoom kom zoo tshaj plaws, ib txwm tshuaj xyuas thiab hloov cov khoom siv idler ua ib qho system thaum pom tias muaj kev hnav ntau. Kev sib xyaw cov khoom hnav thiab cov khoom tshiab tuaj yeem ua rau kev hnav tsis sib xws, tsis sib haum, thiab txo qis kev ua haujlwm. Kev tshuaj xyuas qhov nruj ntawm txoj kev khiav tsis tu ncua, kev hloov cov saw hlau raws sijhawm, thiab kev roj nplua nyeem kom zoo yog cov txheej txheem zoo tshaj plaws rau kev ua kom lub neej ntev ntawm idler.
Lub idler feem ntau yog thawj qhov chaw cuam tshuam thaum lub tshuab ntsib teeb meem, thiab nws qhov kev ua tsis tiav tuaj yeem ua rau txoj kev puas tsuaj loj heev. Kev tsim idler kom zoo, kev xaiv cov khoom siv, thiab kev tsim khoom raug cuam tshuam ncaj qha rau kev sib dhos ntawm txoj kev, kev tswj hwm kev nruj, kev nqus dej poob siab, thiab kev ua haujlwm ntev ntawm lub hauv qab.
