Kev ceev faj rau dov bearing installation:
1. Bearing installation:
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 tsis muaj xuab zeb.
Bearings yuav tsum tau ntxuav ua ntej installation, siv tom qab ziab, thiab xyuas kom meej lubrication zoo. Cov kabmob feem ntau yog lubricated nrog roj, tab sis tuaj yeem lubricated nrog roj. Thaum siv roj lubrication, cov roj uas muaj kev ua haujlwm zoo 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 lub tog raj kheej tau ntim cov 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 qhov chaw ntawm lub ntsej muag kawg ntawm lub ferrule kom nias lub ferrule hauv. . Thaum muaj kev cuam tshuam me me, lub ntsej muag kawg ntawm lub nplhaib bearing tuaj yeem nias nrog lub tes tsho ntawm chav tsev kub, thiab lub tes tsho tuaj yeem raug ntaus nrog rauj taub hau kom nias lub nplhaib sib npaug ntawm lub tes tsho. Yog tias ntsia rau hauv ntau qhov ntau, hydraulic presses 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.
Kev ntsuas kev sib hloov yuav tsum tau nqa tawm rau kev teeb tsa bearing. Ua ntej, nws yog siv rau rotating ncej los yog bearing box. Yog tias tsis muaj qhov txawv txav, nws yuav khiav nrog lub zog tsis muaj kev thauj khoom thiab ntawm qhov ceev, thiab tom qab ntawd maj mam nce qhov kev sib hloov ceev thiab thauj khoom raws li kev ua haujlwm, thiab kuaj xyuas lub 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 tuaj rau kev siv tsuas yog tom qab qhov kev xeem khiav yog qhov qub.
2. Bearing disassembly: Thaum lub bearing yuav tsum tau siv tas li tom qab dismantling, ib tug tsim nyog disassembly cuab tam yuav tsum tau xaiv. Thaum tshem tawm lub 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 tshem tawm los ntawm cov khoom dov, txwv tsis pub cov dov cov ntsiab lus thiab cov raceway yuav raug crushed.
3. Kev siv ib puag ncig ntawm cov kabmob: Raws li kev siv ib feem thiab cov kev siv thiab ib puag ncig, cov kev qhia tshwj xeeb, qhov loj thiab qhov tseeb raug xaiv, thiab cov kabmob uas tsim nyog raug muab sib xyaw kom ntseeg tau tias lub neej thiab muaj peev xwm ntawm cov kabmob.
1). Siv cov khoom: 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 hubs ntawm tsheb, tsav bevel gears, sib txawv Gearboxes, reducers thiab lwm yam kis tau tus mob qhov chaw.
2). Tso cai ceev: nyob rau hauv ib puag ncig ntawm kev txhim kho kom raug thiab lubrication zoo, qhov tso cai ceev yog 0.3-0.5 npaug ntawm qhov txwv ceev ntawm cov kabmob. Raws li ib txwm muaj, 0.2 lub sij hawm qhov txwv ceev yog qhov tsim nyog tshaj plaws.
3). Tso cai inclination lub kaum sab xis: Tapered rau cov menyuam bearings feem ntau tsis tso cai rau cov ncej kom inclined txheeb ze rau lub tsev qhov. Yog tias muaj inclination, qhov siab tshaj plaws yuav tsum tsis pub tshaj 2′.
4). Tso cai kub: Nyob rau hauv ib txwm load, thiab lub lubricant muaj kub tsis kam thiab txaus lubrication, cov kabmob dav dav tau tso cai ua haujlwm ntawm qhov ntsuas kub ntawm -30 degree mus rau 150 degree .
