Nws feem ntau tshwm sim tias lub suab txawv txawv tau pom nyob rau hauv pem hauv ntej ntawm lub tsheb thaum nws txav mus, uas yuav muaj zog dua thaum nrawm thiab txo qis thaum nres. Nws tsis muaj teeb meem dab tsi iav qhov no tshwm sim hauv, qhov txhaum yog nrog lub hub lossis nrog cov kabmob sib txawv. Yuav hloov li cas, tswj nws thiab nws muaj li cas yuav tau tham hauv kab lus.

Differential bearing device

Tapered bearing yog hais txog hom dov bearings thiab yog ib qho tsim muaj ob lub nplhaib nyob rau hauv daim ntawv ntawm ib tug truncated cone nrog khiav grooves. Nruab nrab ntawm lawv yog ib tug separator nrog rollers. Nyob rau hauv cov duab, lawv yog cylindrical, conical, chim-puab, koob-puab thiab twisted. Conical nyob rau hauv lawv tsim yog muab faib ua ib kab thiab ob kab.

Raws li lub ntsiab ntawm lub tshuab, qhov sib txawv ntawm cov kabmob muaj peev xwm ua haujlwm nyob rau hauv cov xwm txheej ntawm kev thauj khoom siab thiab kev sib hloov ceev. Yog li ntawd, tapered bearings yog ib feem ntawm ob lub axlebox sib dhos rau railway thauj, thiabhub ntsiab ntawm lub tsheb.

Vim li cas tus kabmob sib txawv yuav tsum tau hloov?

Hom kev tsis xws luag tau muab faib ua pawg hauv qab no:

1. Thawj qhov tsis xws luag:

• depreciation;
• furrows;
• badass;
• kev puas tsuaj ntawm txheej txheej;
• rust;
• xov xwm ntawm kev hla hluav taws xob.

2. Secondary defects:

• nplawm plhaub;
• gap.

Yog tias muaj qhov tsis xws luag, yuav tsum muaj kev cuam tshuam. Cov kabmob tsis tuaj yeem kho tau, tsuas yog hloov pauv tau xwb.

Yuav ua li cas kho dua tshiab?

Yuav ua kom rov qab ua haujlwm koj yuav xav tau:

1. 2 pob bearings
2. Gaskets (roj foob) ntawm cov tsav hauv tus nqi ntawm 2 pcs.
3. Lub nplhaib. Yuav tsum sib txawv: sab xis thiab sab laug.
4. Gearbox pan sab hauv.
5. xov tooj.
6. New gearbox oil.

Txhawm rau kho qhov sib txawv ntawm qhov sib txawv, koj yuav tsum tshem lub gearbox. Lawv raug kho nyob rau hauv lub dismantled unit nrog lub tso zis ncej iav (tseem ceeb khub) tso tawm. Tom qab lub thawv tau raug tshem tawm lawm, qhov sib txawv raug tshem tawm ntawm nws.

Cov hauv qab no ua tiav:

1. Tsab iav tawm ntawm qhov sib txawv, tig 900.
2. Siv cov cuab yeej tsim nyog, lub nplhaib tuav tau raug tshem tawm, uas nyob hauv qhov axis ntawm lub zog.
3. Tom qab tshem tawmtus nres tau yooj yim tau lub qag thiab, ua ke nrog nws, lub zog lawv tus kheej.
4. Lub taub hau ntawm qhov xav tau loj yog muab, ib qho txuas txuas ntxiv, ces cov bolts yog unscrewed uas fasten lub iav tsav mus rau qhov sib txawv thav duab.
5. Tom qab ntawd cov iav tsav tau tawm ntawm lub tsev (koj tuaj yeem siv rauj).

Tam sim no koj yuav tsum tau saib ntawm qhov chaw ua haujlwm ntawm cov khoom uas tau muab tshem tawm rau qhov tsis xws luag. Yog tias pom qhov tsis sib xws me me, lawv yuav tsum tau muab tshem tawm nrog cov ntawv xuab zeb. Yog tias muaj kev puas tsuaj loj dua rau cov khoom, nws yuav tsum tau hloov. Tsis tas li ntawd, yog tias, thaum kuaj xyuas, chips, plhaub lossis lwm yam tsis xws luag pom ntawm lub iav tsav, ces nws yuav tsum tau hloov.

txheej txheem hloov

kauj ruam tom ntej yog ua tib zoo saib ntawm qhov chaw ntawm cov kabmob. Yog tias muaj kev ua haujlwm nyob rau hauv cov chaw no, lub tsev yuav tsum tau hloov pauv, yog tias lub plhaub tau pom ntawm cov lem thiab dov cov ntsiab lus, ib qho indentation imprint los yog ib qho tsis xws luag hauv cov khoom sib cais, ces cov bearings raug hloov. Tom qab ntawd, siv lub cuab yeej, cov bearings ntawm qhov sib txawv yog kaw. Cov rings sab nrauv yog crimped los ntawm lub gearbox vaj tse. Lawv ua qhov no nrog lub cuab yeej tshwj xeeb. Yog tias tsis muaj ruber, ces cov lapels ntawm lub axles yog thawj crimped, ces lawv hloov nrog tshiab sawv daws yuav.

Cov nplhaib sab nraud raug tshem tawm nrog hwj txwv. Hauv qab lawv muaj lub nplhaib hloov kho. Ua ntej compressing lawv, nws yog ib qhov tsim nyog los npaj cov ntawv luam ntawm cov khoom tshiab. Yog xav tau, lub iav lub luag hauj lwm rauspeedometer. Qhov sib txawv tom qab hloov cov kabmob yog rov ua dua.

VAZ sib txawv bearing hloov

Differential - ib chav tsev uas tso cai rau koj faib lub torque thaum txhua lub qag shafts tau txais nws cov newtonometers. Nws kuj kho qhov ceev ntawm kev sib hloov ntawm lub log. Thaum tig, lub log sab nraud hla dhau ib qho loj arc thiab pib plam. Txhawm rau tiv thaiv qhov no, siv qhov sib txawv.

Vim nws, lub log muaj lub kaum sab xis sib txawv ntawm qhov nrawm. Txhawm rau kho cov ntsiab lus no rau qhov xwm txheej ntawm kev khiav, nws yog qhov yuav tsum tau kho qhov sib txawv.

Cov ntsiab lus muaj ob ntu: lub nplhaib sab nraud, uas yog clamped rau hauv cov thom khwm ntawm tus choj; thiab internal, ramming uas mus rau qhov sib txawv. Koj tuaj yeem ua qhov hloov pauv, nrog rau kev hloov kho ntawm cov nodes, nrog koj tus kheej tes.

Kho qhov sib txawv bearings:

1. Loosen qhov txuas ntawm lub hau bearing kom cov txiv ntoo hloov tau.
2. Cov txiv ntoo no yuav tsum tau ceev cov kabmob me me.
3. Tighten cov bearings nrog ceev, tig lub iav ua ntej nyob rau hauv ib qho kev taw qhia, ces nyob rau hauv lub opposite direction. Thaum qhov no ua tiav, cov chais uas nyob hauv cov kabmob yog nyob rau hauv txoj haujlwm xav tau.
4. txhawm rau ntsuas qhov sib txawv ntawm qhov sib txawv ntawm qhov kawg ntawm lub zog tsav ntawm lub tsheb qag, koj yuav tsum tau ntxiv dag zog rau tus taw tes, nqa nws qhov kev sojntsuam mus rau sab saum toj ntawm tus hniav raws ntug sab nrauv ntawm lub iav. Qhov sib txawv yuav tsum yog 0.15-0.2 hli. Kev ntsuas yuav tsum tau coj los ntawm tsawg kawg yog rau tus hniav hauvrov qab crown zones.
5. Yuav kom txo tau qhov kev ncua deb, siv lub hau ntswj lossis ib lub pas hlau nyias, cov txiv ntoo rau kev kho cov ntug ntawm lub iav rov qab yog unscrewed, thiab lwm yam yog twisted.

Lapel thiab inversion ntawm txiv ntseej yuav tsum tau ua los ntawm tib tus nqi, taw qhia lawv raws cov grooves. Txhua qhov kev sib tw yuav tsum ua kom tiav nrog lub puff. Qhov kev txiav txim no ua kom ruaj khov kev sib cuag ntawm lub nplhaib sab nraud ntawm cov kabmob nrog cov txiv ntseej, uas, dhau los, ua haujlwm lav kev kho thaum lub sijhawm ua haujlwm. Txhawm rau nce qhov kev ncua deb, koj yuav tsum ua tib yam kauj ruam, tab sis nyob rau hauv qhov kev txiav txim rov qab.

Txhim kho cov kauj ruam

1. Tom qab kho qhov kev ncua deb, nws yuav tsum tau kuaj xyuas qhov ua si ntawm lub qag. Txhawm rau ua qhov no, lub pointer txuas nrog lub koob yees duab, qhov kev sojntsuam nyob rau qhov kawg ntawm lub iav tsav. Lub backlash yog ntsuas, thiab ib feem sways nyob rau hauv cov kev taw qhia ntawm lub axis.
2. Cov txiv ntoo hloov kho, uas nyob rau sab nraud ntawm lub iav tsav, teeb tsa lub nraub qaum ntawm lub axis ntawm 0.055 txog 0.035 hli.
3. Tom qab ntawd cov txiv ntseej yog nruj thiab cov preload yog teem: 0.1 hli, yog hais tias tus bearing mileage tsis ntau tshaj 10 txhiab km; 0.05 hli - yog tias ntau tshaj 10 txhiab km. Tig lub txiv ntoo ib lub qhov sib npaug ntawm 0.03 hli "compression" ntawm cov kabmob.
4. Tom qab ua qhov kev hloov kho, ceev cov bolts ntawm lub hau bearing thiab nruab cov ntawv xauv. Qhov kev ncua deb rov qab xyuas dua.

Txhim kho ntawm UAZ sib txawv bearings

Cov txheej txheem no yuav tsum tau ua los ntawm kev kho qhov tuab ntawm cov txheej ntawm cov ntaub qhwv rau kev hloov kho, uas tau muab tso rau ntawmob sab ntawm lub nplhaib kaw ntawm ob lub bearings thiab lub thawv iav. Thaum hloov cov iav tseem ceeb thiab cov kabmob sib txawv, ua qhov kev hloov kho hauv qhov kev txiav txim no:

1. Tam lub kaw cov kabmob ntawm cov txiv ntoo kom muaj qhov nrug ntawm 3-3.5 hli ntawm ob sab ntawm lub thawv iav thiab ob sab ntawm cov kabmob kaw.
2. Tshem tawm cov ncej qag thiab muab qhov sib txawv sib dhos nrog cov iav uas tau tsav rau hauv lub crankcase, txhim kho cov hlua thiab lub hau, tsis txhob nruj cov bolts uas tuav lub hau, thiab, tig lub iav tsav nrog cov hniav sib dhos. los ntawm lub caj pas crankcase, khiav cov bearings thiaj li yuav ua rau cov rollers sawv nyob rau hauv qhov chaw. Tom qab ntawd ntsia lub hau rau lub crankcase tib txoj kev thiab tag.
3. Unscrew lub bolts. Ua tib zoo tshem lub hau, tshem tawm qhov sib txawv ntawm lub qag tsev thiab siv lub ntsuas ntsuas ntsuas qhov deb A thiab A1 ntawm ob sab ntawm lub thawv iav thiab kaw cov kabmob rings.
4. Xaiv cov ntaub qhwv nrog lub thickness uas sib npaug rau cov lej ntawm A + A1. Txhawm rau tiv thaiv lub preload nyob rau hauv bearings ntawm qhov tsis siv neeg kis sib txawv, ntxiv 0.1 hli tuab gasket rau cov teeb no. Yog li ntawd, tag nrho cov tuab yuav tsum yog A + A1 + 0.1mm.
5. Tshem tawm cov kabmob sib txawv kaw. Txiav cov kab sib dhos ua ke rau hauv ob sab. Muab lawv tso rau ntawm caj dab ntawm lub iav lub thawv thiab tamp lub kaw bearing rings mus rau qhov txwv. Tom qab ntawd kho qhov kev ncua deb ntawm ob sab los ntawm kev txav lub iav tsav.

Tsuas yog tom qab hloov cov kabmob sib txawvcoj kev ntsuas thiab sib piv qhov siab ntawm lub rooj sib txoos tshiab thiab qub. Yog tias cov kabmob tshiab loj dua lossis me dua li qhov tsis siv los ntawm ib qho nyiaj, ces txo qhov tuab ntawm cov txheej txheem uas twb muaj lawm hauv thawj version thiab ua kom ntau dua hauv qhov thib ob.

Zoo kawg

Qhov no yooj yim npaum li nws kho thiab hloov cov kabmob sib txawv. Tsab ntawv kuj tau qhia lawv txog lawv lub cuab yeej thiab lub hom phiaj. Yog tias koj muaj teeb meem ntau dua nrog qhov sib txawv, nws zoo dua, tau kawg, tig mus rau cov kws tshaj lij.
