Radial loads yog feem ntau hom quab yuam bearings nrog. Qhov ntawd yog lub zog thawb rau ntawm lub ncej, zoo li qhov hnyav ntawm txoj siv conveyor nias rau ntawm nws cov menyuam, lossis lub tsheb lub log uas txhawb nqa lub tsheb qhov hnyav.
Xaiv qhov zoo bearing rau radial loads yog ib yam. Tab sis khaws nws los ntawm overheating yog lwm qhov. Cia peb taug kev los ntawm koj cov kev xaiv thiab tom qab ntawd tham txog yuav ua li cas kom tsis txhob kub siab los ntawm kev tua koj cov kabmob.
Cov Bearings twg yog qhov zoo tshaj plaws rau Radial Loads?
Tsis yog txhua tus bearings yog tsim sib npaug thaum nws los txog rau tuav radial quab yuam. Nov yog qhov shortlist:
1. Deep Groove Pob Bearings
Cov no yog tag nrho cov - rounders. Lawv tuav radial loads zoo heev, ntxiv rau qee qhov axial load yog xav tau. Lawv yooj yim, pheej yig, thiab khiav ntawm kev kub ceev. Yog hais tias koj daim ntawv thov yog nruab nrab load thiab nruab nrab ceev, qhov no feem ntau yog mus - mus.
2. Cylindrical Cov Menyuam Bearings
Thaum lub radial load hnyav, koj tsiv mus rau cov menyuam bearings.Cylindrical cov menyuam bearingsmuaj kab sib cuag (es tsis yog qhov chaw sib cuag zoo li cov pob), yog li lawv tuaj yeem nqa ntau dua radial loads. Kev lag luam - tawm? Lawv tsis nyiam axial loads ntau, thiab lawv tsis tshua zam txim rau misalignment. Siv lawv thaum ntshiab radial load yog qhov kev txhawj xeeb tseem ceeb.
3. Koob Cov Menyuam Bearings
Cov no yog cov cylindrical rollers nrog lub taub me me. Lawv haum rau hauv qhov chaw nruj thiab tseem nqa tau ib qho kev hwm radial load. Koj yuav pom lawv nyob rau hauv gearboxes, txuas rods, thiab qhov chaw uas koj tsis tuaj yeem haum rau cov kabmob loj dua.
4. Spherical Cov Menyuam Bearings
Cov no kuj tseem siv thoob -zoo li tus rollers. Lawv zoo heev rau hnyav radial loads, thiab lawv muaj peev xwm lis misalignment ib yam nkaus thiab. Tab sis lawv yog bulkier thiab kim dua. Siv lawv thaum lub taub hau tsis zoo tag nrho los yog lub tsev flexes.
Vim li cas Bearings Thaum tshav kub kub hauv Radial Load?
Kub yog yeeb ncuab. Ib tug bearing uas khiav kub heev yuav poob nwssab hauv clearance, cov roj yuav tawg, thiab thaum kawg nws yuav txeeb los yog poob thaum ntxov.
Vim li cas qhov kub thiab txias tshwm sim?
· load ntau dhau- thawb lub bearing dhau nwsdynamic load ntsuastsim kev sib txhuam ntau dhau.
· Tsis txaus lubrication- yog tias cov roj lossis roj zaj duab xis tsis tuab txaus, hlau kov cov hlau.
· Cov roj nplua nyeem tsis raug- qhov tsis ncaj ncees lawm viscosity tsis tuaj yeem tsim cov yeeb yaj kiab kom zoo ntawm kev ua haujlwm kub.
· Tshaj - roj- roj ntau dhau churns thiab generates tshav kub es tsis txhob tsuas yog lubricating.
· Tight internal clearance- yog tias cov kabmob tau nruab nrog tsawg dhauradial internal clearance (C3, C4, thiab lwm yam), thermal expansion tuaj yeem ua rau nws khi.
· Kev tsis ncaj ncees- txawm me ntsis ncej misalignment ntxiv zog ntxiv uas tsim kev sib txhuam thiab kub.
Yuav ua li cas tiv thaiv kub nce (cov kauj ruam tswv yim)
Nov yog qhov ua tau zoo hauv thaj teb kom radial-load bearings txias.
1. Xaiv qhov kev tshem tawm sab hauv.
Tsis txhob cia li rub tus qauv (CN) tshem tawm cov kabmob rau qhov kub - khiav daim ntawv thov. Mus rauC3(nce clearance) los yog txawmC4yog tias muaj qhov kub thiab txias tseem ceeb los yog ncej expansion. Qhov chaw ntxiv ntawd cia cov kabmob tuav cov thermal loj hlob yam tsis tau nyem cov khoom dov.
2. Siv hom lubricant kom raug thiab tus nqi.
Rau siab radial loads, siv roj nrog zooEP (hnyav siab) additives. Xyuas lub hauv paus roj viscosity thiab. Yog tias cov kabmob khiav kub, koj yuav xav tau cov roj hluavtaws lossis cov roj kub siab - kub. Thiab tsis txhob overdo nws. Sau cov kabmob thiab vaj tse txog 30-50% puv nrog roj. Ntau tsis zoo dua.
3. Xyuas kom lub vaj tse thiab ncej haum zoo.
Yog tiastsev bore haumyog nruj heev, lub nplhaib sab nraud tau nyem thiabradial clearanceploj lawm. Ib yam li ntawd, ib yam nkaus - nrujncej haumtuaj yeem nthuav lub nplhaib sab hauv. Ua raws li cov kev pom zoo (xws li k5 rau shafts, H7 rau vaj tse rau ntau daim ntawv thov).
4. Tshawb xyuas kev sib tw tsis tu ncua.
Ib tug misaligned ncej tso uneven radial load ntawm cov kabmob, tsim cov kub kub. Siv lub dial taw qhia lossis lub laser alignment tool kom cov khoom ncaj nraim.
5. Saib xyuas qhov kub thiab txias hauv lub sijhawm.
Yog hais tias nws yog ib tug tseem ceeb tshuab, muab ibthermocouplenyob rau hauv lub bearing vaj tse. Teem lub tswb ntawm 80-90 degree. Qhov ntawd muab sijhawm rau koj tshawb xyuas ua ntej kev puas tsuaj tshwm sim.
6. Ua kom muaj cua sov kom zoo.
Qee lub sij hawm tus kabmob nws tus kheej yog qhov zoo, tab sis lub vaj tsev ntxiab cua sov. Ntxiv cov cua txias, siv lub kiv cua, lossis hauv qhov xwm txheej hnyav, nthuav cov roj los ntawm lub tsev kom nqa cov cua sov mus.
