1. Bearings nyob rau hauv motors
Nyob rau hauv hluav taws xob motors, bearings yog siv los txhawb lub cev muaj zog ncej. Bearings kuj tseem siv los txuas cov khoom siv lub cev ua ke. Cov kabmob yog cov cuab yeej siv tshuab uas tso cai rau peb hloov lub zog thiab txav tau yooj yim. Cov kabmob tuaj yeem muab faib ua ob hom: pob bearings thiab cov menyuam bearings.
Pob bearings feem ntau yog siv nyob rau hauv qis speeds thiab nyob rau hauv high load li xws li motors. Cov menyuam bearings feem ntau yog siv nyob rau hauv kev kub ceev daim ntawv thov thiab tsis tshua muaj loads xws li tsav shafts, axles thiab spindles.
Cov kabmob xav tau ob qho tib si hauv lub tshuab hluav taws xob thiab sab hauv cov tshuab hluav taws xob vim lawv tso cai rau cov tshuab no ua haujlwm. Lub hom phiaj yog los txhawb thiab tso lub rotor.
Lub luag haujlwm ntawm cov kabmob yog txhawb nqa thiab tso lub rotor. Lub cev muaj zog ncej yog txhawb los ntawm bearings ntawm lub puab thiab txheej dov cov ntsiab lus (pob los yog rollers) uas tig nrog lub ncej.
Cov kabmob yuav tsum muaj peev xwm tiv taus lub zog centrifugal, kev vibrations thiab acceleration thaum pib thiab nres thiab thaum ua haujlwm. Feem ntau cov kabmob yog ua los ntawm steel lossis aluminium alloys. High-quality bearings kuj muaj nyob rau hauv corrosive ib puag ncig.
2. Hom kabmob muaj nyob rau hauv motors
Nyob rau hauv hluav taws xob motors, muaj ntau hom bearings siv. Cov no muaj xws li pob bearings, cylindrical roller bearings, spherical roller bearings thiab tapered roller bearings. Txhua hom muaj cov yam ntxwv tshwj xeeb uas ua rau nws haum rau qee yam kev siv.
Pob bearings yog qhov zoo tshaj plaws rau kev siv me me cylindrical nkaus xwb thaum tus nqi ntawm cov kabmob tuaj yeem nqa tau. Cov menyuam bearings ua haujlwm zoo tshaj plaws hauv cov khoom hnyav, xws li cov motors lossis cov cav. Bearings nyob rau hauv motors yog siv los txo kev sib txhuam poob.
Bearings pab txo cov khoom siv hluav taws xob poob thiab xav tau kev saib xyuas los ntawm kev txo qis kev sib txhuam ntawm cov khoom txav. Kev sib txhuam yog tshwm sim los ntawm kev sib cuag ntawm lub cev ntawm ob yam khoom. Nyob rau hauv ib lub cev muaj zog, muaj ntau qhov chaw txav mus rau ib leeg, ua rau muaj kev sib txhuam thiab kub. Thaum tshav kub kub yog tsim los ntawm kev sib txhuam, ua rau kub hauv bearings thiab lwm yam khoom. Qhov no tuaj yeem ua rau lub cev muaj zog lossis lwm yam khoom puas.
Txhawm rau txo kev sib txhuam, motors siv bearings. Bearings pab txo lub zog poob thiab txuas ntxiv lub neej ntawm lub cev muaj zog los ntawm kev txo cov cua sov ntau dhau los ntawm kev sib txhuam ntawm cov khoom txav.
Bearings ua kom yooj yim rau tig. Bearings yog siv nyob rau hauv lub cev muaj zog kom cia tus ncej tig. Lawv tuaj yeem tsim los ntawm ntau yam khoom sib txawv, suav nrog hlau, tooj dag, lossis yas. Steel bearings yog muaj kaw los yog unsealed. Cov kabmob uas kaw tau yuav khaws cov av thiab plua plav tawm thaum cov kabmob uas tsis tau ntim cia cia cov plua plav nkag.
Txhawm rau ua kom lub cev muaj zog tig nrawm dua koj yuav tsum siv cov bearings ntawm no ntawm tus ncej thiab nws yuav pab txo qis kev sib txhuam ntawm lub ncej kom nws tuaj yeem tig tau nrawm dua.
Qhov no yog vim li cas bearings kuj siv nyob rau hauv lub tsheb gearboxes, lawv pab hloov lub zog ntawm ib lub iav mus rau lwm yam tsis muaj kev sib txhuam ntau. Lub cev muaj zog hloov hluav taws xob hluav taws xob mus rau hauv lub tshuab hluav taws xob. Feem ntau hom motors yog AC motors thiab DC motors. AC motors hloov lub zog rau hauv kev sib hloov, thiab DC motors yuav coj lub zog mus rau hauv kev sib hloov.
3. Kev siv tseem ceeb ntawm lub cev muaj zog bearings
1. Yooj yim rau tig.
2. Bearings yog tsim los txhawb nqa radial loads, uas yog lub zog uas thawb lossis rub ib qho khoom los ntawm ntau cov lus qhia nyob ib ncig ntawm nws qhov ncig.
3. Bearings kuj muab kev sib txhuam tsis sib hloov ntawm cov khoom txav. Cov kabmob uas yob tawm tsam ib leeg es tsis txhob sib tsoo ncaj qha tuaj yeem txhim kho kev ua haujlwm ntawm lub cev muaj zog.
Bearings yog cov khoom tseem ceeb rau ntau yam kev siv sib txawv. Lawv yog siv nyob rau hauv ntau yam lag luam nyob rau hauv ntau yam machinery thiab khoom siv. Bearings pab txo kev sib txhuam thiab txhim kho kev ua haujlwm ntawm ntau hom motors thiab tshuab.
4. Cov kabmob txo kev sib txhuam ntawm cov khoom txav. Kev sib txhuam yog kev tiv thaiv kev sib txheeb ntawm ob qhov chaw sib cuag. Qhov no ua rau nto hnav thiab yog li kev sib txhuam poob hauv qhov system. Los ntawm kev siv cov bearings, kev sib txhuam poob tuaj yeem raug txo los yog tshem tawm tag nrho, uas yuav txuas ntxiv lub neej ntawm koj lub cav lossis lub tshuab.
5. Siv lub cev muaj zog bearings lossis tshuab: txo cov nqi kho. Thaum tsis muaj kev sib txhuam me me los yog tsis muaj kev sib txhuam ntawm cov khoom txav, cov loads thiab kev ntxhov siab tsawg dua ntawm cov khoom; yog li ntawd, lawv tsis tas yuav hloov, feem ntau yog tias koj tsis siv lawv lossis yog tias koj siv cov bearings tsis zoo piv rau koj li. Tsis muaj qhov txo qis hauv kev sib txhuam koj tuaj yeem tau txais los ntawm cov khoom zoo.
6. Lub cev muaj zog siv cov kabmob kom txo cov suab nrov
4. Kev loj hlob zeem muag ntawm bearings hauv motors
Bearings yog qhov tseem ceeb tshaj plaws ntawm lub cev muaj zog vim tias lawv tso cai rau nws khiav zoo thiab ntsiag to. Cov bearings tso cai rau lub rotor tig ywj siab ntawm tus ncej. Cov bearings nyob rau hauv lub kiv cua no yog tib yam li cov nyob rau hauv ib tug xyaum los yog lub hwj chim cuab yeej. Lawv muaj cov pob dov ntawm ob haiv neeg (lossis daim phiaj) nrog lub qhov drilled rau hauv lawv. Cov npas haum rau hauv cov qhov no thiab tso cai rau lub rotor tig smoothly, tsis muaj suab nrov lossis kev co. Cov bearings hauv lub cev muaj zog khiav ruaj khov.
Bearings yog qhov tseem ceeb hauv kev ua haujlwm ruaj khov ntawm cov cav. Lawv yog ib qho tseem ceeb rau kev ua haujlwm zoo ntawm cov motors thiab lwm yam kev hloov tshuab.
Bearings yog siv nyob rau hauv tag nrho cov hom ntawm lub cev muaj zog, txawm lawv yog hluav taws xob motors, hydraulic motors los yog hydroelectric dams. Cov kabmob tso cai rau kev sib hloov du yam tsis muaj kev sib txhuam lossis hnav. Muaj ntau ntau hom bearings nrog ntau lub zog thiab kev siv.
Bearings tseem hu ua cav bearings thiab muaj nyob rau hauv yuav luag txhua hom cav, los ntawm lub tsheb mus rau hluav taws xob motors thiab los ntawm dav hlau mus rau nkoj. Vim tias cov kabmob tuaj yeem txo qhov kev sib txhuam thiab hnav ntawm ob qhov chaw txav, kev txhim kho kev ua haujlwm thiab lub neej ntawm lub cev muaj zog yog qhov tseem ceeb rau peb niaj hnub siv. Raws li cov bearings thawj zaug tshwm sim hauv tsheb thiab tsheb ciav hlau, lawv tau dhau los ua neeg nyiam thiab tau maj mam siv hauv lwm qhov chaw.
