1. Yuav ua li cas rau nruab tapered menyuam bearings:
Bearings yuav tsum tau muab ntsia rau hauv qhuav, huv si ambient tej yam kev mob. Ua ntej kev teeb tsa, lub machining zoo ntawm qhov chaw mating ntawm lub ncej thiab lub vaj tsev, qhov kawg ntawm lub xub pwg nyom, grooves thiab qhov sib txuas yuav tsum tau ua tib zoo xyuas. Tag nrho cov mating nto yuav tsum tau ua tib zoo ntxuav thiab deburred, thiab unmachined nto ntawm castings yuav tsum tau ntxuav ntawm residual molding xuab zeb.
Ua ntej kev teeb tsa, cov kabmob yuav tsum tau ntxuav nrog roj av lossis roj av, siv tom qab ziab, thiab xyuas kom zoo lubrication. Cov kabmob feem ntau yog lubricated nrog roj lossis roj. Thaum siv roj lubrication, cov roj nrog kev ua haujlwm siab xws li tsis muaj impurities, tiv thaiv oxidation, tiv thaiv xeb thiab siab siab yuav tsum tau siv. Cov roj filling yog 30 feem pua -60 feem pua ntawm cov kabmob thiab cov kabmob vaj tsev ntim, thiab yuav tsum tsis txhob ntau dhau. Ob chav kab tapered cov menyuam bearing nrog cov qauv kaw thiab cov twj tso kua mis twj tso kua mis tau ntim nrog roj, uas tuaj yeem siv ncaj qha los ntawm tus neeg siv thiab tsis tuaj yeem ntxuav dua.
Thaum cov kabmob raug teeb tsa, qhov sib npaug ntawm lub siab yuav tsum tau siv rau ntawm lub voj voog ntawm lub ntsej muag kawg ntawm lub ferrule kom nias lub ferrule nyob rau hauv, thiab nws tsis raug tso cai rau ncaj qha mus tsoo lub ntsej muag kawg ntawm cov kabmob nrog lub hoe lossis lwm yam cuab yeej kom tsis txhob muaj. kev puas tsuaj rau cov kabmob. Nyob rau hauv cov ntaub ntawv ntawm kev cuam tshuam me me, lub ntsej muag kawg ntawm lub nplhaib bearing tuaj yeem nias nrog lub tes tsho ntawm qhov kub thiab txias, lub tes tsho tuaj yeem raug ntaus nrog lub hoe, thiab lub nplhaib tuaj yeem nias sib npaug ntawm lub tes tsho. Yog tias muaj ntau qhov kev teeb tsa, cov xovxwm hydraulic tuaj yeem siv tau. Thaum nias rau hauv, nws yuav tsum xyuas kom meej tias lub ntsej muag kawg ntawm lub nplhaib sab nraud thiab lub ntsej muag kawg ntawm lub xub pwg ntawm lub plhaub, thiab lub ntsej muag kawg ntawm lub nplhaib puab thiab lub ntsej muag kawg ntawm lub xub pwg nyom yog nias kom nruj, thiab tsis muaj qhov sib txawv. tso cai. Thaum qhov cuam tshuam loj heev, nws tuaj yeem ntsia tau los ntawm cov roj da dej cua sov lossis inductor cua sov cov txheej txheem. Cov cua kub ntau yog 80 degree -100 degree, thiab qhov siab tshaj plaws tsis tuaj yeem tshaj 120 degree. Nyob rau tib lub sijhawm, zawm cov kabmob nrog cov txiv ntseej lossis lwm txoj hauv kev tsim nyog los tiv thaiv cov kabmob ntawm qhov dav ntawm qhov kev taw qhia tom qab txias thiab ua rau muaj qhov sib txawv ntawm lub nplhaib thiab lub xub pwg nyom.
Kev hloov kho clearance yuav tsum tau nqa tawm thaum kawg ntawm lub installation ntawm ib kab tapered menyuam bearing. Tus nqi tshem tawm yuav tsum tau txiav txim siab raws li kev ua haujlwm sib txawv thiab qhov loj ntawm kev cuam tshuam. Thaum tsim nyog, kev ntsuam xyuas yuav tsum tau ua los txiav txim siab. Ob chav kab tapered menyuam bearing thiab lub twj tso kua mis ncej bearing tau raug kho rau clearance ntawm lub Hoobkas, thiab tsis tas yuav tsum tau kho thaum lub sij hawm installation.
Tom qab cov kabmob raug teeb tsa, kev ntsuas kev sib hloov yuav tsum tau ua. Ua ntej, tig lub ncej los yog cov kabmob ntawm tes. Yog tias tsis muaj qhov txawv txav, khiav nws nrog lub hwj chim tsis muaj kev thauj khoom thiab ntawm qhov ceev, thiab maj mam nce qhov kev sib hloov ceev thiab thauj khoom raws li kev khiav hauj lwm, thiab xyuas cov suab nrov, kev vibration thiab kub nce. , Yog tias pom muaj qhov txawv txav, kev ua haujlwm yuav tsum tau nres thiab kuaj xyuas. Nws tuaj yeem xa mus rau kev siv tsuas yog tom qab qhov kev xeem khiav yog qhov qub.
2. Bearing disassembly:
Thaum cov kabmob yuav tsum tau txuas ntxiv siv tom qab raug tshem tawm, yuav tsum xaiv cov cuab yeej tshem tawm uas tsim nyog. Thaum disassembling lub puab ferrule nrog kev cuam tshuam haum, tsuas yog rub lub zog tuaj yeem siv rau lub ferrule, thiab nws tsis raug tso cai kom xa cov quab yuam disassembly los ntawm cov khoom dov (nplhaib sab nraud), txwv tsis pub lub caij dov thiab txoj kev sib tw yuav raug crushed.
3. Kev siv ib puag ncig ntawm cov kabmob:
Raws li qhov chaw siv, siv cov xwm txheej thiab ib puag ncig, xaiv qhov loj thiab qhov tseeb, thiab koom tes nrog cov kabmob tsim nyog yog qhov chaw ua haujlwm kom ntseeg tau tias lub neej thiab kev ntseeg tau.
1. Siv cov khoom siv: Tapered roller bearings yog tsim rau cov kabmob sib xyaw ua ke radial thiab axial loads feem ntau raws li radial loads. Lawv feem ntau yog siv ua khub nrog ob pawg ntawm cov kabmob. Lawv tsuas yog siv nyob rau hauv pem hauv ntej thiab nram qab log hubs, tsav bevel gears, sib txawv zog ntawm tsheb. Gearboxes, reducers thiab lwm yam kis tau tus mob.
2. Tso cai rau kev sib hloov ceev: Nyob rau hauv ib puag ncig ntawm kev txhim kho kom raug thiab lubrication zoo, nws raug tso cai ua 0.3-0.5 npaug ntawm qhov txwv rotational ceev ntawm cov kabmob. - Raws li ib txwm muaj, qhov txwv ceev ntawm 0.2 zaug yog qhov tsim nyog tshaj plaws.
3. Tso cai rau lub kaum sab xis: tapered cov menyuam bearings feem ntau tsis tso cai rau tus ncej kom inclined txheeb ze rau lub qhov nyob. Yog tias muaj inclination, qhov siab tshaj plaws yuav tsum tsis pub tshaj 2 degrees.
4. Tso cai qhov kub thiab txias: Nyob rau hauv ib txwm load, thiab lub lubricant muaj qhov kub thiab txias tsis kam thiab lubrication txaus, cov kabmob dav dav raug tso cai ua haujlwm ntawm qhov ntsuas kub ntawm 30 degree ---150 degree.
4. Txoj kev teeb tsa ntawm tapered roller bearings
1. Kev txhim kho txoj kev thrust tapered roller bearing
Thrust cylindrical roller bearings thiab thrust koob rau cov menyuam bearings yog tsim rau lub sijhawm uas tsis tshua muaj kev sib hloov ceev, thrust tapered menyuam bearings nrog me ntsis flatter rotational speeds, thiab thrust bearings mas dais axial loads nyob rau hauv lub rooj sib txoos, thiab yog dav siv. Txawm hais tias lub thrust bearing installation ua haujlwm.
2. Yuav ua li cas cov iav thiab tapered cov menyuam bearings sib sau ua ke?
Thaum tsim lub iav, yuav tsum muaj ib qho axial positioning kauj ruam, lub nplhaib sab nraud ntawm cov kabmob raug kaw, thiab sab nraud ntawm lub nplhaib sab hauv yog kaw nrog lub ntsuas phoo, thiab lub pre-tightening quab yuam ntawm lub xauv yog teem raws li. cov ntaub ntawv thov.
3. Yuav ua li cas rau nruab thiab kho qhov clearance ntawm tapered menyuam bearings?
Feem ntau, tapered roller bearings yog siv, ob lub ntsej muag-rau-ntsej muag thiab rov qab-rau-rov qab. Qhov luaj li cas ntawm qhov kev tshem tawm yuav tsum tau txiav txim siab raws li qhov loj ntawm cov kabmob uas koj xaiv thiab qhov kev sib kis qhov tseeb yuav tsum tau ua los ntawm cov txheej txheem los xaiv pawg tshem tawm! Raws li txoj kev hloov kho, nws tuaj yeem pom tau los ntawm kev nias thiab loosening.
