Vim li cas tus hla cylindrical roller bearing plam? Yog vim li cas thiab kev tiv thaiv plam
Hla cov menyuam bearings yog ib qho ntawm feem ntau siv dov bearings. Txawm li cas los xij, qee tus neeg ua rau cov kabmob nkig thaum lub sijhawm ua haujlwm vim qee qhov laj thawj, uas yuav cuam tshuam rau kev ua haujlwm thiab kev ua haujlwm ntawm tag nrho cov khoom siv. Yog li, yog vim li cas tus hla cylindrical roller bearing plam? Yuav ua li cas kom tsis txhob ntog?
Ⅰ.Ua rau ntawm cov menyuam bearing slippage
Hla cylindrical roller bearing Slippage ntawm crossed cylindrical roller bearing lub rooj yog qhov tsim nyog rau khawb lub rooj zaum bearing, tab sis qhov tshwm sim ntawm slipping tsis tas yuav ua rau nto khawb. Piv txwv li, qhov kev vibration ntawm lub ncej thiab lub alternating load tsim ib tug quab yuam uas yuav rhuav tau lub lubricating roj zaj duab xis thiab ua rau khawb ntawm tej qhov chaw ntawm lub chaw ua hauj lwm nto (qhov chaw ua hauj lwm ntawm lub nruas thiab lub puab nplhaib raceway yog ntau dua). Yog li ntawd, nws yog qhov tseeb tias qhov kev raug mob slipping yog tshwm sim los ntawm kev hloov khoom siv vim yog kev sib cuam tshuam ntawm cov hlau tsis sib xws tom qab cov yeeb yaj kiab lubricant puas lawm. Qee cov ntaub ntawv yog "stained tam sim ntawd" los tsim cov pits; hos qhov ntau stained qhov protrude saum lub qhov qub nto. Tsis tas li ntawd, qee qhov ntawm qhov chaw ua haujlwm yog khawb, thiab qee qhov tsis muaj khawb, uas yog ze ze rau qhov kev hloov pauv thiab qhov degree ntawm kev puas tsuaj rau lub tes tsho. Nyob rau hauv cov xwm txheej hnyav, kev sib txhuam ntau dhau yog tsim los ntawm cov menyuam thiab cov nplhaib puab, uas ua rau lub nplhaib sab hauv nthuav dav, txo cov radial clearance, thiab ua rau lub rooj zaum ntawm cov kabmob.
Ⅱ. Hla cov menyuam bearing plam kev ua haujlwm
Thaum cov kabmob ua haujlwm, cov chais yuav tsum ua kom huv si dov rau ntawm lub nplhaib sab hauv thiab sab nraud. Yog hais tias tus tsav tsheb lub tawb yuav tsum muaj lub zog rub txaus, nws tuaj yeem kov yeej nws qhov kev tawm tsam. Thaum cov menyuam rub lub zog tsis txaus los kov yeej qhov kev tawm tsam, lub sijhawm no, ntxiv rau dov, yuav muaj qee qhov zawv zawg, thiab tus txheeb ze qhov sib txawv ntawm kev khiav ceev ntawm lub nplhaib sab hauv (los yog lub nplhaib sab nraud) yog qhov tshwm sim ntawm plam.
Ⅲ. Anti-skid ntsuas rau hla cov menyuam bearings
1. Txo tus naj npawb ntawm cov menyuam thiab cov menyuam txoj kab uas hla
Cov menyuam yog txav los ntawm lub nplhaib tig. Thaum lub zog tso cai, txo nws qhov hnyav kom ua tiav lub hom phiaj ntawm kev txo qis inertial tsis kam. Nws yog ib qho tseem ceeb heev los tiv thaiv thiab txo qhov zawv zawg. Hauv aero-turbine xyaw, vim qhov me me ntawm cov khoom siv sab nraud, kev sib cuag nrog qaug zog tsis yog qhov kev puas tsuaj loj ntawm lub nruas. Raws li cov qauv kev cai, lub bearing loj kam rau ua yog tseem loj. Nws yog feem ntau txiav txim siab tias tus naj npawb ntawm cov chais raug txo los ntawm 50 feem pua, thiab tom qab txoj kab uas hla tau txo los ntawm 25 feem pua, nws tseem tsis cuam tshuam rau nws lub neej qaug zog.
2. Xaiv cov qauv tsim nyog thiab txo qhov hnyav ntawm lub tawb
Ntxiv rau qhov txo nws qhov hnyav thaum lub zog tso cai, lub tawb ntawm cylindrical cov menyuam bearings yuav tsum xav txog nws tus kheej cov yam ntxwv, piv txwv li, yuav tsum zam nws cov resonance thiab high-speed rotation kuj. Txoj kev taw qhia lub tawb kuj yog ib qho tseem ceeb heev nyob rau hauv high-speed bearing vaj tse. Yog tias qhov tsis sib xws ntawm lub tawb yog tswj kom zoo, lub tawb tau hloov los ntawm cov kev taw qhia sab nrauv mus rau sab hauv kev taw qhia, uas tseem muaj txiaj ntsig zoo rau kev txo qis. Vim hais tias ntawm cov kev taw qhia sab nrauv, cov txheeb ze txav ntawm lub tawb thiab cov kev taw qhia saum npoo ntawm cov kabmob, cov roj lubricating cov yeeb yaj kiab ua rau cov ntaub ntawv tsis muaj zog, thaum cov lus qhia sab hauv yog qhov sib txawv, thiab cov viscous quab yuam ntawm lubricating zaj duab xis ntawm lub tawb thiab phau ntawv qhia. nto los ua ib tug quab yuam. Nyob rau hauv txoj kev no, lub viscous kuj dhau los ua lub zog uas rub lub tawb kom tig. Qhov sib txawv ntawm ob tsis tuaj yeem tsis quav ntsej.
3, cov khoom siv roj hauv qab lub nplhaib
Qhov kom zoo dua ntawm kev siv cov roj hauv qab lub nplhaib yog tias nws tshem tawm cov cua sov ntawm lub rooj zaum ntawm cov kabmob thiab tib lub sijhawm ua rau qhov poob ntxiv los ntawm kev sib tw me me. Lwm qhov piv txwv yog hloov lub nplhaib sab nrauv siv ribs mus rau sab hauv lub nplhaib siv ribs, uas undoubtedly tuaj yeem txo qhov tsis kam ntawm kev sib xyaw.
4. Txais hollow cov menyuam preload bearing
Hollow cov menyuam preload bearing tuaj yeem siv preload rau txhua qhov yob, kom txhua qhov chaw tsis plam. Vim muaj kev khiav hauj lwm ceev thiab kub ntau ntawm turbine cav rotor bearings, yuav tsum tau saib xyuas kom xaiv qhov tsim nyog preload. Txawm tias nyob rau hauv ib tug tsawg heev sab nraud load, ib tug ntau preload yuav tseem ua rau lub nruas puas lawm. Hom kev ua tsis tiav yog khoov qaug zog.
5. Siv oval bearings
Siv lub rooj zaum elliptical bearing yog ib hom kev tsis plam, feem ntau muaj ob hom knots, ob-lobed thiab peb-lobed. Ua ib qho piv txwv ntawm ob-lobed elliptical bearing. Feem ntau, lub nplhaib sab nraud ntawm lub nplhaib sab nraud ntawm cov kabmob no yog elliptical, thiab sab hauv txoj kab uas hla (raceway) ntawm lub nplhaib sab nraud thiab lub rooj zaum bearing yog ob qho tib si ncig. Tom qab sib sau ua ke, lub nplhaib sab nrauv txoj kev sib tw ua elliptical, uas yog, preload yog siv rau lub nruas. Uas yog hais tias, lub radial clearance ntawm cov menyuam thiab cov raceway ntawm lub luv semi-axis ntawm lub elliptical raceway yog tshem tawm (kev cuam tshuam yog tsim), thiab cov menyuam yog compressed. Yog li ntawd, nyob rau hauv tas li ntawd mus rau lub ob peb rollers nyob rau hauv qab yog raug rau lub ntiajteb txawj nqus load ntawm lub rotor, lub rollers ntawm 90 degree mus rau sab laug thiab sab xis kuj raug rau ib tug tej yam nqi ntawm preload, yog li ua rau kom tus naj npawb ntawm rollers bearing lub load. mus rau rollers. Kwv yees li 60 feem pua ntawm tag nrho (lub tog raj kheej cov menyuam bearings feem ntau dais txog 20 feem pua ntawm tag nrho cov menyuam bearing load). Yog li ntawd, ua kom lub zog rub tau zoo los tiv thaiv cov menyuam thiab lub tawb kom tsis txhob ntog. Txawm li cas los xij, txoj kev muab lub ovality yuav txo qhov qaug zog lub neej ntawm lub rooj zaum bearing, yog li nws yog ib qho tsim nyog yuav tau xav txog kev xaiv qhov tsim nyog ovality hauv kev siv.
Ⅳ. Cov yam ntxwv cuam tshuam rau qhov slippage ntawm hla cov menyuam bearings
1, lub nplhaib puab ceev
Lub nplhaib puab ceev yog ib qho tseem ceeb uas cuam tshuam rau cov menyuam swb ntawm tus ntoo khaub lig cov kabmob. Cov menyuam slip tus nqi yog generated raws li lub puab nplhaib rotates, txo nrog rau qhov nce ntawm lub siab generated los ntawm kev cuam tshuam haum, thiab nyhav stabilize nrog nce lub sij hawm, nrog rau kev hloov pauv.
2, radial load
Nyob rau hauv tus txheej txheem uas cov menyuam swb tus nqi txo nrog qhov nce ntawm radial load, cov menyuam ceev fluctuates, thiab yoj amplitude nce nrog lub sij hawm nce. Tom qab cov kabmob nkag mus rau hauv lub xeev khov kho, cov menyuam swb tus nqi txo qis nrog qhov nce ntawm cov radial load, thiab muaj kev sib raug zoo uas tsis yog-linear ntawm ob.
3, gap
Nrog rau qhov nce ntawm qhov clearance ratio, lub tawb txav lub xeev nyhav yuav tsis muaj teeb meem, ua rau muaj kev sib tsoo hnyav ntawm cov menyuam thiab lub tawb hnab tshos, thiab lub zog ntawm ob qhov nce, thiab lub tawb qhov cuam tshuam rau cov menyuam txav tau ntxiv dag zog thiab nruj. Cov menyuam skidding.
4, kev sib txhuam yam
Raws li qhov kev sib txhuam zoo zuj zus, cov menyuam txoj kev slippage nyob rau hauv lub load-bearing cheeb tsam thiab tsis-load-bearing cheeb tsam yog suppressed. Qhov no yog vim qhov kev sib txhuam ntawm cov menyuam thiab cov kev sib tw sab hauv thiab sab nrauv hauv qhov chaw thauj khoom yog lub zog tsav rau cov menyuam. Thaum qhov kev sib txhuam ntawm ob qhov nce, lub zog tsav tsheb nce ntxiv thiab cov menyuam yaus tsis tshua muaj kev sib tw, lub plam yog suppressed; nyob rau hauv qhov chaw uas tsis yog-load-bearing, qhov nce ntawm qhov kev sib txhuam yuav ua rau muaj kev sib txhuam ntawm lub nplhaib sab nrauv rau cov menyuam, uas yog, lub zog tsav tsheb nce, thiab slipping tsis yooj yim tshwm sim.
Paub tias yog vim li cas tus cross roller bearing slips, thiab nrog nws raws li txoj kev sib raug zoo, thiaj li yuav pab tau zoo dua rau kev siv cov cylindrical roller bearing thiab txo tus nqi ntawm nws cov txij nkawm thiab hloov. Hauv kev siv txhua hnub, peb kuj yuav tsum tau ua qhov cuam tshuam los tiv thaiv kev tiv thaiv rau cov menyuam cylindrical bearings.
