Nws yog inevitable tias muaj qhov txawv txav thaum lub sij hawm ua haujlwm bearing. Peb cov kev txawv txav feem ntau yog lub suab nrov, qhov kub thiab txias nce, kev co loj (kev ntaus ntawm lub axis) thiab cov dej xau, thiab lwm yam. Dab tsi yog qhov laj thawj tshwj xeeb rau lub xeev txawv txav? Yuav ua li cas nrog cov kev txawv txav tom qab cov kev txawv txav no. Tuam Tshoj Bearing Network ua cov lus teb ntxaws.
1. Cov suab nrov
Yog hais tias lub bearing nyob rau hauv ib tug zoo sib law liag lub xeev, nws yuav ua ib tug qis whine los yog buzzing suab. Yog hais tias lub suab nrov nrov, squeak, thiab lwm yam suab tsis raug, nws feem ntau qhia tau hais tias cov kabmob yog nyob rau hauv kev sib txuas tsis zoo. Lub suab nrov squeak yuav tshwm sim los ntawm lubrication tsis tsim nyog. Cov kabmob tsis tsim nyog tuaj yeem ua rau muaj suab nrov.
Peb qhov tseem ceeb ntawm kev coj tus kheej lub suab nrov yog: lub suab nrov hlau loj, tswj cov suab nrov thiab lub suab tsis zoo.
1. Lub suab nrov hlau loj
Qhov laj thawj tseem ceeb ntawm lub suab nrov ntawm cov hlau loj los ntawm kev coj tus kheej yog cov khoom tsis zoo, kev teeb tsa tsis zoo, cov roj nplua nyeem tsis txaus, thiab tsis muaj kev sib cuag nrog cov khoom sib hloov.
Countermeasures uas ua rau bearing abnormal loads: kho thiab kev koom tes, kawm lub bearing sib txawv, kho lub pre-load, thiab kho lub plhaub los thaiv lub xub pwg txoj hauj lwm.
Countermeasures ua rau tsis zoo bearing installation: ua qhov tseeb ntawm ncej thiab plhaub, txhim kho installation raug, thiab installation txoj kev.
Cov kev ntsuas uas ua rau cov roj ntsha tsis txaus: ntxiv cov roj nplua nyeem thiab xaiv cov roj nplua nyeem uas tsim nyog.
Ua rau cov kabmob sib hloov qhov chaw nrog kev sib cuag: Hloov kho qhov sib cuag ntawm lub tshuab sealing.
2. Lub suab nrov ntawm cov cai
Qee lub sij hawm cov kabmob yuav tshwm sim thaum lub sijhawm ua haujlwm, "呲-呲, tsis tu ncua, thiab tshwm sim tsis tu ncua". Qhov no yog lub suab nrov ntawm cov cai. xeb, nti, (tom qab steel carburizing), deformation deformation thiab cov menyuam nto tawg.
Bearing countermeasures tshwm sim los ntawm txawv teb chaws qhov chaw dov los tsim indentation, xeb, thiab nti: Hloov cov bearings, ntxuav cov khoom muaj feem xyuam, txhim kho lub sealing ntaus ntawv, thiab siv ib tug huv si lubricant.
Kev ntsuas rau qhov deformation ntawm cov kabmob (tom qab steel carburizing): hloov cov bearings thiab xyuam xim rau nws siv.
Countermeasures uas ua rau cov kabmob dov txoj kev nto: Hloov cov bearings
3. Lub suab tsis zoo
Piv txwv li, "squeak, irregular sounds, thiab tsis muaj suab ntawm kev hloov nyob rau hauv lub ceev ntawm kev sib hloov yuav tshwm sim thaum lub sij hawm lub bearing lub luag hauj lwm ntawm lub ntsiab: ntau sib txawv, txawv teb chaws lub cev ntxeem tau thiab puas thiab tawg.
Countermeasures ua rau qhov sib txawv ntawm cov kabmob ntau dhau: Kawm hauv kev koom tes thiab cov kabmob sib kis los hloov kho qhov ntim ua ntej.
Kev tiv thaiv kev cuam tshuam ntawm cov khoom txawv teb chaws hauv cov kabmob: Kawm hloov cov kabmob, ntxuav cov khoom muaj feem xyuam, txhim kho cov khoom sib khi, thiab siv cov roj nplua nyeem huv.
Kev ntsuas ntawm cov kabmob pob puas lossis tawg: Hloov cov kabmob.
Qhov thib ob, qhov kub ntawm cov kabmob abnormality nce
Tom qab pib ua haujlwm, cov kabmob yuav tsum sov. Tom qab ib lub sijhawm, nws khiav ntawm qhov kub thiab txias (feem ntau yog 10-40 degrees siab dua li chav tsev kub).
Nws belongs rau ib txwm, thiab cov bearings kuj tuaj yeem sib txawv raws li qhov loj ntawm qhov loj. Nyob rau hauv nruab nrab, thaum lub bearing kub tsis ncav cuag qhov sov sov, peb yuav xav txog qhov phem yam.
1. Cov roj nplua nyeem ntau dhau lossis tsawg dhau
Kev ntsuas kev ntsuas: Txo lossis ntxiv cov roj nplua nyeem, siv nws nyob rau hauv qhov nruab nrab, thiab tsis tu ncua hloov cov kabmob mus rau cov kabmob hloov cov roj nplua nyeem lossis roj, thiab xaiv cov roj hnyav dua.
2. Cov roj nplua nyeem tsis haum
Lub lubricant ntawm cov kabmob tsis ua raws li qhov yuav tsum tau muaj lossis tsis muaj paug. Kev xaiv cov roj lubricating tsis tsim nyog. Nws tsis yog ib qho yooj yim rau daim ntawv lubricating roj zaj duab xis. Nws tsis tuaj yeem txo qhov kev sib txhuam sab hauv thiab hnav ntawm cov bearings, lubrication tsis txaus, thiab nce qhov kub ntawm cov bearings.
Countermeasure: Lub lubricant tsim nyog yuav tsum tau xaiv rau bearings.
3. Disposter load
Countermeasures: Hloov kho thiab koom tes, kawm qhov sib txawv ntawm cov kabmob, thiab kho cov khoom ua ntej kom hloov kho lub plhaub sab nraud los thaiv lub xub pwg nyom.
4. Kev teeb tsa tsis zoo
Kev teeb tsa tsis raug yog lwm qhov laj thawj tseem ceeb rau cov cua sov ntawm cov kabmob. Vim tias qhov kev teeb tsa bearing yog qhov tseeb lossis tsis yog, nws muaj kev cuam tshuam ncaj qha rau nws lub neej thiab qhov tseeb ntawm tus tswv tsev. Yog li ntawd, nws yuav tsum tau hais tias lub ncej yuav tsum tau overlapped nrog lub hauv paus kab ntawm lub bearing qhov thaum lub sij hawm installation.
Countermeasure: Txhim kho qhov ua tau zoo, kev teeb tsa raug, thiab kev teeb tsa ntawm lub plhaub plhaub.
5. Kev koom tes nrog cov creep, lub sealing ntaus ntawv rub tawm ntau dhau
Countermeasures: Hloov cov bearings, kawm kev koom tes, hloov lub plhaub ncej, thiab hloov daim ntawv sealing ntaus ntawv.
Thib peb, kev co (ntaus ntawm axis)
Qhov laj thawj tseem ceeb ntawm cov kabmob vibrations yog plaub yam: (tom qab steel carburizing) deformation deformation, tawg, tsis zoo installation, thiab txawv teb chaws lub cev ntxeem tau.
(Tom qab steel carburizing) Nto deformation countermeasures: Ua tib zoo saib xyuas kev sib pauv thiab kev ua haujlwm.
Countermeasures of bearing break: Hloov cov bearings.
Kev tiv thaiv tsis zoo rau kev teeb tsa cov kabmob: Hloov kho lub kaum sab xis ntawm lub ncej, lub plhaub thaiv lub kaum sab xis, thiab sab ntawm lub ncoo.
Countermeasures ntawm bearing txawv teb chaws cov khoom: Hloov cov bearings, huv si, txhim kho sealing pab kiag li lawm, thiab lwm yam.
Piv txwv li, kev siv tes ua haujlwm tsis zoo tsis ua raws li qhov yuav tsum tau ua. Lub rotor txav thiab tsis sib npaug, lub hauv paus tsis zoo, lub hauv paus ntawm ko taw tsis txaus, kev sib hloov stagnation thiab mob hawb pob. Qee lub rotor Thaum lub sijhawm ua haujlwm, vim qhov corrosion ntawm nruab nrab los yog hnav ntawm cov khoom impurities, los yog dabtsi yog khoov ntawm axis, nws yuav ua rau unbalanced centrifugal quab yuam, uas ua rau cov bearings kub thiab vibrate, thiab cov menyuam yog hnyav heev hnav. mus txog thaum nws puas lawm.
Plaub, lubricant to, discoloration
Qhov ua rau to thiab discoloration ntawm bearing lubricant yog: lubricant ntau dhau lawm, txhuam hmoov nyob rau hauv txawv teb chaws lub cev ntxeem tau, thiab lwm yam.
Kev ntsuas kev ntsuas: Siv cov roj nplua nyeem nyob rau hauv qhov nruab nrab, kawm thiab hloov cov kev xaiv ntawm lubricants, kawm txog kev hloov cov bearings, thiab ntxuav lub plhaub.
