Bearings tau nyob ib puag ncig txij li cov neeg Iyiv thaum ub tau tsim cov pyramids. Lub tswvyim tom qab lub log cov kabmob yooj yim: yam yob zoo dua li lawv swb. Thaum cov khoom swb, kev sib txhuam ntawm lawv ua rau lawv poob qis. Yog tias ob qhov chaw tuaj yeem muab ib leeg rau ib leeg, kev sib txhuam yog txo qis. Cov neeg Iyiv thaum ub tso cov cav nyob rau hauv cov pob zeb hnyav kom lawv thiaj li muab kev txhuam ntawm lub pob zeb.
Txawm hais tias bearings txo kev sib txhuam ua kev sib txhuam zoo, lub log log log bearings tseem siv ntau yam kev tsim txom. Tsis tsuas yog lawv yuav tsum txhawb qhov hnyav ntawm koj lub tsheb thaum mus ncig ua si, lawv yuav tsum ua tag nrho cov log tsheb, thiab yuav tsum ua txhua yam kev sib txhuam ntawm cov kev sib txhuam tsawg kawg nkaus ib feeb. Lawv kuj yuav tsum yog tus kheej-txaus thiab kaw nruj kom tiv thaiv cov hmoov av thiab dej paug. Niaj hnub log log bearings yog ruaj khov kom ua tiav tag nrho cov no. Tam sim no uas muaj nqis!
Feem ntau cov tsheb muag hnub no tau nruab nrog cov log bearings uas tau muab ntim rau hauv lub hub sib dhos thiab yuav tsum tsis muaj kev saib xyuas. Cov kabmob ntim tau nyob ntawm cov tsheb tshiab tshaj plaws, thiab nyob sab pem hauv ntej lub tsheb ntawm tsheb thiab SUVs nrog kev ncua sab xub ntiag. Kaw cov log bearings yog engineered rau lub neej pabcuam ntau tshaj 100,000 mais, thiab ntau yam muaj peev xwm mus ob zaug uas nyob deb. Txawm li ntawd, qhov nruab nrab bearing lub neej muaj npaum li cas los ntawm 80,000 txog 120,000 mais nyob ntawm seb lub tsheb twg yog qhov raug.
Ib hube ib txwm muaj ib sab hauv thiab sab nraud cov kabmob log. Bearings yog tog los yog cov menyuam lossis cov pob. Tapered rau cov menyuam cov kabmob yog qhov kev xaiv zoo tshaj plaws txij li lawv tau txais kev txhawb nqa ob qho tib si kab rov tav thiab tom qab ntim thiab tuaj yeem sawv kev poob siab heev xws li kev tsoo lub raj tshuaj. Tapered Bearings tau cov kabmob sib tw nyob ntawm lub kaum sab xis. Tapered rau cov menyuam cov kabmob feem ntau yog mounted ua khub nrog lub kaum sab xis ntsib cov lus qhia rov qab yog li lawv tuaj yeem ua raws li ob qho kev qhia. Cov menyuam steel cov kabmob yog cov nruas me me uas txhawb nqa lub nra. Lub taper lossis kaum sab xis txhawb nqa kab rov tav thiab tom qab chaw thau khoom.
Log bearings yog tsim siv cov khoom lag luam zoo thiab loj li cas cov hlau. Sab hauv thiab sab nraud sib tw, ib ncig nrog ib tug zawj uas cov pob uas cov pob lossis cov menyuam ntim, cov pob lossis cov pob, yog txhua qhov chaw sov. Qhov tawv tawv tawv ntxiv ntxiv rau cov coj tsis kam ntawm cov kabmob.
Ib lub tsheb nruab nrab hnyav ncig 4,000 lbs. Qhov no yog ntau qhov hnyav uas yuav tsum tau txais kev txhawb nqa ntau ntau txhiab mais. Ua kom ua raws li qhov xav tau, log bearings yuav tsum nyob rau hauv yuav luag zoo tus mob, muaj kev ua kom muaj lubrication, thiab raug muab ntim rau kom ua kom lubricant hauv thiab paug tawm. Txawm hais tias lub log bearings yog engineered kom kav ntev, tas mus li thauj thiab tig rov qab siv tus xov tooj ntawm cov kabmob, roj, thiab ntsaws ruaj ruaj. Ua ntej lub log coj los ntawm kev puas tsuaj vim kev cuam tshuam rau kev cuam tshuam, paug, ploj ntawm cov roj, lossis kev sib xyaw ntawm cov no.
Thaum lub log coj cov log thaiv pib pib rau xau, cov kabmob tau pib txheej txheem ua tsis tiav. Ib qho kev puas tsuaj roj uas yuav tso tawm rau cov roj tawm ntawm cov kabmob, thiab cov av thiab dej tuaj yeem nkag mus rau cov kab noj hniav. Dej yog qhov phem tshaj plaws rau bearings thaum nws ua rau xeb thiab paug cov roj. Vim tias qhov hnyav ntau yog caij ntawm lub log bearings thaum tsav tsheb thiab sib tw, txawm tias muaj kev puas tsuaj tsawg tshaj plaws yuav tsim suab nrov.
Yog hais tias cov ntsaws ntsaws rau ntawm cov kabmob sib dhos sib dhos ua ke swb, cov ntsaws ruaj ruaj tsis tuaj yeem hloov nyias. Tag nrho cov hub sib dhos los ua ke yuav tsum tau hloov. Log bearings uas tsis yog lub Hoobkas kaw, uas muaj tsawg kawg nkaus hnub no, xav tau kev saib xyuas ib ntus. Lawv yuav tsum tau ntxuav, kuaj xyuas, rov qab muaj roj tshiab, thiab muaj cov ntsaws ruaj ruaj ntsia kwv yees li ntawm txhua 30,000 mais lossis raws li cov chaw tsim khoom pom zoo.
Thawj qhov tsos mob ntawm cov log cov teeb meem yog suab nrov los ntawm ib puag ncig ntawm lub log. Nws feem ntau pib nrog lub nus audible loj hlob, whirring, humming, lossis qee yam suab nrov cyclic. Lub suab nrov yuav feem ntau nce zuj zus li lub tsheb tsav. Lwm cov tsos mob yog kauj wandering los ntawm kev sib tw ntau dhau mus ua si.
Cov suab nrov log tsis hloov pauv thaum nrawm lossis txiav tawm thaum tab sis yuav hloov thaum tig rov qab. Tej zaum nws yuav dhau los ua rouder lossis txawm ploj ntawm qee qhov nrawm. Nws yog ib qho tseem ceeb kom tsis meej meej lub log uas nrov nrov nrog lub suab nrov nrog lub suab nrov, lossis nrog lub suab nrov tsis sib haum (CV) sib koom tes ua. Faulty CV pob qij txha feem ntau ua suab nrov txhaj tshuaj thaum tig.
Kev kuaj cov suab nrov lub suab nrov tsis yooj yim. Txiav txim siab qhov twg ntawm koj lub tsheb bearings yog ua kom lub suab nrov kuj tseem tuaj yeem nyuaj, txawm tias yog tus thev naus laus zis raws caij nyoog. Yog li ntawd, ntau cov tshuab feem ntau pom zoo hloov ntau lub log bearings nyob rau tib lub sijhawm raws li lawv yuav tsis paub tseeb tias ib qho ua tsis tau.
Ib txoj hauv kev los tshawb xyuas cov log bearings yog los tsa lub log tawm hauv av thiab tig txhua lub log los ntawm kev sib dhos thiab kev ua si hauv lub hub. Ntawm cov tsheb nrog kaw log bearings, yuav luag tsis muaj kev ua si (tsawg dua .004 ntiv tes ntawm feem ntau) lossis tsis muaj kev ua si, thiab tsis muaj suab nrov lossis suab nrov. Kev kuaj xyuas kev ua si tuaj yeem ua tiav los ntawm kev tuav lub log ntawm 12 teev thiab 6 teev thiab co lub log tsheb rov qab. Yog tias muaj ib qho kev ua si pom tau, lub log bearings yog xoob thiab yuav tsum tau hloov lossis pabcuam.
Faulty log bearings kuj tseem cuam tshuam koj lub tsheb lub anti-xauv qhov chaw nres (ABS). Kev ua si ntau dhau, hnav, lossis looseness nyob rau hauv lub hub yuav feem ntau ua rau lub taub hau ntiv nplhaib rau wobble thaum nws tig. Lub log tsheb ceev sensors yog rhiab heev rau kev hloov pauv ntawm huab cua sib txawv ntawm qhov ntxeev ntawm sensor thiab lub nplhaib sensor. Thiaj li, cov kabmob hnav log yuav ua rau muaj teeb liab tsis zoo uas yuav teeb lub log ceev sensor teeb meem kev teeb meem thiab ua rau lub teeb tsis ceeb toom tuaj.
Lub log cov kabmob tsis ua haujlwm yuav ua tsis tau muaj peev xwm tshwm sim, tshwj xeeb yog tias nws tshwm sim thaum tsav tsheb ntawm kev loj ceev thiab lub tsheb poob lub log. Yog vim li cas koj yuav tsum tau tus asne tus neeg muaj ntawv pov thawj cov neeg txawj kuaj koj cov kabmob log tsawg kawg nkaus, thiab sim tsav koj lub tsheb los mloog cov lus tsis muaj teeb meem.
