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

Cov neeg siv khoom ib txwm yws txog lub neej ua haujlwm ntawm cov bearings, tab sis 80% ntawm cov bearings ua tsis tiav ua ntej lub sijhawm vim yog kev teeb tsa tsis raug. Kev teeb tsa cov bearings kom raug tsis tsuas yog ua rau lawv lub neej ua haujlwm ntev dua thiab txo cov nqi, tab sis kuj tseem txhim kho kev tsim khoom ntau ntxiv.

Raws li paub zoo, cov bearings lawv tus kheej yog cov khoom siv rau kev txhawb nqa thiab tseem yog cov khoom siv los txhawb kev sib hloov ntawm cov ncej. Cov bearings tuaj yeem faib ua pawg los ntawm lawv cov khoom sib txhuam rau hauv cov bearings swb thiab cov bearings dov. Raws li kev taw qhia ntawm lub nra uas lawv ris, muaj cov bearings radial, Kev Tawm Tsams, thiab radial thrust bearings, thiab lwm yam.

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. 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 rauj. Hauv cov xwm txheej tshwj xeeb, txoj kev teeb tsa kub tau txais yuav. Feem ntau cov bushings yog ua los ntawm tooj liab lossis hlau cam khwb cia. Thaum sib sau ua ke, yuav tsum ceev faj. Lawv tuaj yeem sib sau ua ke los ntawm kev ntaus nrog rauj ntoo lossis rauj nrog lub thaiv ntoo. Thaum qhov kev cuam tshuam haum kam rau siab loj, lawv yuav tsum tau nias rau hauv nrog lub nias. Txawm hais tias nws raug khob rau hauv lossis nias rau hauv, yuav tsum tiv thaiv kev tilting. Tom qab sib sau ua ke, qhov roj groove thiab qhov roj qhov 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 rau kev txiav; rau cov loj dua, siv cov scrapers. Tib lub sijhawm, xyuam xim rau kev tswj qhov sib txawv ntawm qhov sib haum nrog lub qag hauv qhov ntau yam kev kam rau siab. Txhawm rau tiv thaiv lub tes tsho qag los ntawm kev 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 qag thiab lub tsev. Vim yog qhov sib txawv ntawm lub cev lub thawv thiab cov ntaub ntawv tes tsho qag, thaum tho, nws yooj yim heev rau lub laum me ntsis kom nqes mus rau sab khoom mos. Cov kev daws teeb meem yog: ua ntej, siv lub tshuab xuas piv txwv los tho lub qhov tawm tsam sab khoom tawv ua ntej tho; qhov thib ob, siv lub laum me ntsis luv luv los ua kom lub laum me ntsis ruaj khov thaum tho.

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.

● Kev sib dhos ntawm lub bushing thiab 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.

● 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.

● 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, lub plhaub kabmob raug khawb tawm ua ntej, thiab tom qab ntawd lub plhaub kabmob sab saud raug khawb tawm. Txhawm rau txhim kho kev ua haujlwm, lub plhaub kabmob thiab lub hau tsis tas yuav tsum tau ntsia thaum khawb lub plhaub kabmob. Thaum qhov chaw sib cuag ntawm lub plhaub kabmob qis ua tau raws li qhov yuav tsum tau ua, lub plhaub kabmob sab saud thiab lub hau sab saud raug nias kom nruj. Thaum khawb lub plhaub kabmob sab saud, qhov chaw sib cuag ntawm lub plhaub kabmob qis raug kho ntxiv. Thaum khawb, qhov nruj ntawm lub ncej tuaj yeem hloov kho los ntawm kev hloov qhov tuab ntawm lub gasket thaum tus lej ntawm lub sijhawm khawb nce ntxiv. Thaum lub hau kabmob raug nruj, lub ncej tuaj yeem tig tau yooj yim yam tsis muaj qhov pom tseeb, thiab cov ntsiab lus sib cuag ua tau raws li qhov yuav tsum tau ua, kev khawb tiav.

● Kev ntsuas ntawm qhov chaw tsaws

Qhov loj ntawm qhov chaw tso cov kabmob tuaj yeem hloov kho los ntawm lub gasket ntawm nruab nrab-dav hlau lossis los ntawm kev khawb ncaj qha rau lub bearing bush. Qhov chaw tso cov kabmob feem ntau yog ntsuas los ntawm txoj kev nias cov hlau lead. Siv ob peb ntu ntawm cov hlau lead uas muaj qhov loj dua qhov chaw tso cov kabmob thiab muab tso rau ntawm phau ntawv xov xwm thiab qhov chaw nruab nrab. Tom qab ntawd nruj lub txiv ntoo kom nias qhov chaw nruab nrab kom nruj, unscrew lub txiv ntoo, tshem lub hau bearing, thiab ua tib zoo tshem cov hlau lead uas tiaj tiaj. Siv lub micrometer los ntsuas qhov tuab ntawm txhua ntu uas tau txais. Raws li qhov nruab nrab tuab ntawm cov hlau lead, qhov chaw tso cov kabmob tuaj yeem paub. Qhov chaw tso cov kabmob dav dav yuav tsum yog 1.5‰-2.5‰ (mm) ntawm qhov txoj kab uas hla ntawm tus ncej. Thaum qhov txoj kab uas hla loj dua, yuav tsum siv tus nqi tso me dua. Yog tias qhov txoj kab uas hla ntawm tus ncej yog 60mm, qhov chaw tso 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 vaj tse, yuav tsum tsis muaj qhov skew.

Ntawm ob lub bearings ntawm tib lub axis, ib qho yuav tsum ua rau lub ncej txav thaum lub ncej 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 ℃.
