Lub bearing tsis tau teeb tsa kom raug. Qhov teeb meem no loj heev!

Kev sib dhos ntawm cov kabmob swb

Cov kabmob zawv zawg yog ib hom kabmob uas muaj cov yam ntxwv sib txhuam zawv zawg. Lawv muaj tus cwj pwm los ntawm kev ua haujlwm du, kev ntseeg siab, suab qis, thiab muaj peev xwm tiv taus cov khoom hnyav thiab cov khoom cuam tshuam loj. Raws li cov qauv sib txawv, lawv tuaj yeem muab faib ua hom sib xyaw, hom sib cais, thiab hom thaiv, thiab lwm yam.

1. Kev sib dhos ntawm cov kabmob sib txuas ua ke

Cov kabmob sib xyaw ua ke, feem ntau hu ua bushings, yog cov qauv yooj yim tshaj plaws ntawm cov kabmob sib xyaw. Lawv feem ntau yog sib sau ua ke los ntawm kev nias rau hauv thiab hammering. Hauv cov xwm txheej tshwj xeeb, txoj kev teeb tsa kub tau siv. Feem ntau cov bushings yog ua los ntawm tooj liab lossis hlau cam khwb cia.
    
Thaum lub sijhawm sib dhos, yuav tsum ceev faj. Lawv tuaj yeem sib dhos los ntawm kev ntaus nrog rauj ntoo lossis rauj nrog lub thaiv ntoo. Thaum qhov kev cuam tshuam haum loj, lawv yuav tsum tau nias rau hauv. Txawm hais tias nws raug khob rau hauv lossis nias rau hauv, yuav tsum tiv thaiv kev tilting. Tom qab sib dhos, qhov roj thiab qhov roj yuav tsum nyob rau hauv qhov chaw xav tau.
    
Rau cov bearings uas deformed tom qab sib dhos, cov qhov sab hauv yuav tsum tau txiav. Rau cov me me, siv cov reamers los txiav; rau cov loj dua, siv cov scrapers. Tib lub sijhawm, xyuam xim rau kev tswj qhov sib txawv ntawm qhov sib txawv nrog lub qag hauv qhov ntau thiab tsawg.
    
Yuav kom tiv thaiv lub tes tsho ncej kom tsis txhob tig thaum lub sijhawm ua haujlwm, cov pins lossis cov ntsia hlau hla-seam raug ntsia rau ntawm qhov chaw sib cuag ntawm lub tes tsho ncej thiab lub tsev. Vim yog qhov sib txawv ntawm lub cev lub thawv thiab cov ntaub ntawv tes tsho ncej, thaum drilling, nws yooj yim heev rau lub laum kom lean rau sab khoom mos. Cov kev daws teeb meem yog:
* Ua ntej, siv lub tshuab xuas los xuas lub qhov rau sab ntawm cov khoom tawv ua ntej tho.
* Qhov thib ob, siv lub laum luv luv los ua kom lub laum ruaj khov dua thaum lub sijhawm laum.

2. Sib dhos ntawm cov kabmob sib cais

Cov kabmob sib cais, tseem hu ua cov kabmob sib cais, muaj cov qauv yooj yim thiab yooj yim kho thiab rhuav tshem. Muaj ob lub plhaub kabmob ntxig rau ntawm cov plhaub kabmob, thiab siv lub gasket ntawm qhov sib koom ua ke los kho qhov sib txawv tsim nyog.

*A. Kev sib dhos ntawm lub bush bearing thiab lub Lub Tsev Rau Cov Kabmob
Qhov kev sib cuag ntawm lub plhaub sab saud thiab sab hauv qab ntawm lub plhaub bearing thiab lub qhov sab hauv ntawm lub tsev bearing yuav tsum zoo. Yog tias nws tsis ua raws li qhov yuav tsum tau ua, siv lub qhov sab hauv ntawm lub tsev bearing ntawm lub plhaub bearing tuab-walled ua qhov siv los khawb sab nraub qaum ntawm lub plhaub bearing. Tib lub sijhawm, ob kauj ruam ntawm ob qho kawg ntawm lub plhaub bearing yuav tsum nyob ze rau ob qho kawg ntawm lub tsev bearing. Rau cov plhaub bearing nyias-walled, nws tsuas yog tsim nyog ua kom nruab nrab ntawm lub plhaub bearing siab dua li ntawm 0.1 hli ntawm lub tsev bearing, thiab tsis tas yuav khawb nws.
    
*B. Cov kev cai rau kev tso chaw
Lub bush bearing tau teeb tsa rau hauv lub tsev bearing thiab tsis pub muaj kev hloov chaw radial lossis axially. Feem ntau, nws raug nres thiab muab tso rau ntawm cov kauj ruam ntawm ob qho kawg ntawm lub bush bearing lossis los ntawm kev teeb tsa cov pins.
    
*C. Kev khawb cov plhaub ntawm cov kabmob
Rau cov plhaub sib cais ntawm cov kabmob, feem ntau siv cov ntsiab lus sib tsoo sib phim. Feem ntau, cov plhaub kabmob raug khawb tawm ua ntej, thiab tom qab ntawd cov plhaub kabmob sab saud raug khawb tawm. Txhawm rau txhim kho kev ua haujlwm, cov plhaub kabmob thiab lub hau tsis tas yuav tsum tau ntsia thaum khawb cov plhaub kabmob. Thaum qhov chaw sib cuag ntawm cov plhaub kabmob qis ua tau raws li qhov yuav tsum tau ua, cov plhaub kabmob sab saud thiab lub hau sab saud raug nias kom nruj. Thaum lub sijhawm khawb cov plhaub kabmob sab saud, qhov chaw sib cuag ntawm cov plhaub kabmob qis raug kho ntxiv. Thaum khawb, qhov nruj ntawm cov ncej tuaj yeem hloov kho los ntawm kev hloov qhov tuab ntawm lub gasket thaum tus lej ntawm cov sijhawm khawb nce ntxiv. Thaum Cover Bearing yog nruj, lub qag tuaj yeem tig tau dawb yam tsis muaj qhov pom tseeb, thiab cov ntsiab lus sib cuag ua tau raws li qhov yuav tsum tau ua, qhov kev khawb tiav lawm.
    
*D. Kev ntsuas qhov chaw ntawm lub bearing
Qhov loj ntawm qhov chaw tso cai ntawm cov kabmob tuaj yeem hloov kho los ntawm lub gasket ntawm nruab nrab-dav hlau lossis los ntawm kev khawb ncaj qha rau ntawm lub bush bearing. Qhov chaw tso cai ntawm cov kabmob feem ntau yog ntsuas los ntawm txoj kev nias ua los ntawm cov hlau lead:
1. Siv ob peb ntu ntawm cov hlau txhuas uas muaj qhov loj dua qhov chaw tso cai
2. Muab lawv tso rau ntawm phau ntawv xov xwm thiab qhov chaw nruab nrab ntawm qhov chaw sib cais
3. Nias lub txiv ntoo kom nias qhov nruab nrab ntawm qhov chaw sib cais kom nruj.
4. Tshem lub hau ntawm lub txiv ntoo thiab tshem lub hau npog ntawm lub bearing
5. Ua tib zoo tshem cov hlau txhuas uas tiaj tiaj tawm
6. Siv lub micrometer los ntsuas qhov tuab ntawm txhua ntu.
        
Raws li qhov nruab nrab tuab ntawm cov hlau txhuas, qhov kev tshem tawm ntawm cov kabmob tuaj yeem paub. Qhov kev tshem tawm ntawm cov kabmob dav dav yuav tsum yog 1.5‰-2.5‰ (mm) ntawm txoj kab uas hla ntawm tus ncej. Thaum txoj kab uas hla loj dua, tus nqi tshem tawm me dua yuav tsum tau coj. Yog tias txoj kab uas hla ntawm tus ncej yog 60mm, qhov kev tshem tawm ntawm cov kabmob yuav tsum nyob nruab nrab ntawm 0.09 thiab 0.15mm.

Kev sib dhos ntawm cov bearings dov

Cov bearings dov muaj qhov zoo ntawm kev sib txhuam tsawg, qhov me me axial, hloov tau yooj yim thiab yooj yim txij nkawm.

Cov kev cai rau kev sib dhos:

* Cov ntsej muag kawg ntawm cov kabmob dov uas cim nrog cov lej yuav tsum tau teeb tsa rau hauv qhov kev taw qhia pom kom yooj yim rau kev txheeb xyuas thaum hloov pauv.
* Lub vojvoog ntawm lub arc ntawm kauj ruam ntawm phau ntawv xov xwm lossis lub qhov tsev yuav tsum me dua li ntawm qhov chaw sib xws ntawm tus kabmob.
* Tom qab cov kabmob tau sib sau ua ke ntawm lub qhov thiab hauv lub qhov tsev, yuav tsum tsis muaj qhov skew.
* Ntawm ob lub bearings ntawm tib lub axis, ib qho yuav tsum ua rau lub qag txav thaum lub qag nthuav dav thermally.
* Thaum sib sau ua ke cov bearings dov, nws yog ib qho tseem ceeb kom tiv thaiv cov av kom tsis txhob nkag mus rau hauv cov bearings.
* Tom qab sib dhos, cov bearings yuav tsum ua haujlwm tau yooj yim, tsim suab nrov tsawg, thiab qhov kub ua haujlwm feem ntau yuav tsum tsis pub tshaj 65 ℃.
