1. Yuav ua li cas rau nruab tapered menyuam bearings:
Cov kabmob yuav tsum tau muab tso rau hauv qhov chaw qhuav thiab huv si. Ua ntej kev teeb tsa, ua tib zoo xyuas cov machining zoo ntawm cov ncej thiab cov vaj tsev mating nto, ncej xub pwg kawg lub ntsej muag, grooves thiab qhov chaw sib txuas. Tag nrho cov mating thiab txuas qhov chaw yuav tsum tau ua tib zoo ntxuav thiab deburred, thiab residual molding xuab zeb yuav tsum tau muab tshem tawm los ntawm unmachined nto ntawm lub casting.
Cov kabmob raug ntxuav nrog roj av lossis roj av ua ntej kev teeb tsa, siv tom qab ziab, thiab lubricated zoo. Cov kabmob feem ntau yog lubricated nrog roj lossis roj. Thaum siv roj lubrication, roj nrog kev ua haujlwm zoo xws li tsis muaj impurities, oxidation tsis kam, tiv thaiv xeb, thiab siab siab yuav tsum raug xaiv. Cov roj ntim cov roj yuav tsum yog 30% -60% ntawm qhov ntim ntawm cov kabmob thiab cov kabmob vaj tse, thiab yuav tsum tsis txhob muaj ntau dhau. Ob chav kab tapered cov menyuam bearings nrog cov qauv kaw thiab cov dej twj tso kua mis txuas txuas bearings yog greased thiab tuaj yeem siv ncaj qha los ntawm tus neeg siv thiab tsis tuaj yeem ntxuav.
Thaum lub sij hawm bearing mounting, sib npaug siab yuav tsum tau siv rau qhov ncig ntawm lub nplhaib kawg lub ntsej muag kom nias rau hauv lub nplhaib. Nws tsis raug tso cai rau ncaj qha ntaus cov kabmob kawg lub ntsej muag nrog lub cuab yeej xws li rauj kom tsis txhob muaj kev puas tsuaj rau cov kabmob. Thaum qhov kev cuam tshuam me me, nias lub nplhaib bearing kawg lub ntsej muag nrog lub tes tsho ntawm chav tsev kub, ntaus lub tes tsho nrog rauj, thiab 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, xyuas kom meej tias lub nplhaib sab nrauv kawg lub ntsej muag thiab lub xub pwg nyom ntawm lub ntsej muag, lub nplhaib puab kawg lub ntsej muag thiab lub xub pwg nyom kawg lub ntsej muag yog nias yam tsis muaj qhov khoob.
Thaum qhov kev cuam tshuam loj heev, cov kabmob tuaj yeem txuas tau los ntawm cov roj da dej cua sov lossis cua sov induction. Cov cua kub kub yog 80 degree -100 degree, thiab qhov kub siab tsis tshaj 120 degree. Nyob rau tib lub sijhawm, zawm cov kabmob nrog cov txiv ntseej lossis lwm txoj kev tsim nyog los tiv thaiv qhov sib txawv ntawm lub nplhaib thiab lub xub pwg nyom vim shrinkage nyob rau hauv dav kev taw qhia tom qab cov kabmob tau txias.
Lub clearance yuav tsum tau kho nyob rau thaum xaus ntawm lub installation ntawm ib kab tapered menyuam bearing. Tus nqi sib txawv yuav tsum tau txiav txim siab raws li kev siv sib txawv thiab qhov cuam tshuam ntawm qhov haum. Yog tias tsim nyog, yuav tsum tau kuaj xyuas kom paub meej. Qhov kev tshem tawm ntawm ob kab tapered menyuam bearings thiab lub twj tso kua mis ncej bearings tau raug kho thiab tsis tas yuav tsum tau kho thaum lub sij hawm installation.
Tom qab cov kabmob yog mounted, ib qho kev ntsuas kev sib hloov yuav tsum tau ua. Ua ntej, tig lub ncej los yog cov kabmob vaj tse los ntawm tes. Yog tias tsis muaj qhov txawv txav, nws yuav tsum tau khiav qis qis nrog hluav taws xob thiab tsis muaj kev thauj khoom, thiab tom qab ntawd maj mam nce qhov nrawm thiab thauj khoom raws li qhov xwm txheej khiav, thiab kuaj xyuas lub suab nrov, kev vibration thiab kub nce. Yog tias pom muaj qhov txawv txav, nres qhov kev ua haujlwm thiab xyuas. Nws tsuas yog xa tuaj tom qab qhov kev xeem khiav yog qhov qub.
2. Disassembly ntawm bearings:
Thaum siv cov bearings tom qab disassembly, yuav tsum xaiv cov cuab yeej dismounting tsim nyog. Thaum disassembling lub puab ferrule ntawm qhov cuam tshuam haum, lub ferrule tsuas tuaj yeem ua rau qhov nro, thiab nws tsis raug tso cai kom xa lub zog disassembly los ntawm cov khoom dov (nplhaib sab nraud), txwv tsis pub lub caij dov thiab raceway yuav raug crushed.
3. Kev siv ib puag ncig:
Xaiv cov kev qhia tshwj xeeb, qhov ntev thiab qhov tseeb raws li cov khoom siv, kev pabcuam thiab ib puag ncig, thiab kev sib piv cov kabmob zoo yog qhov yuav tsum tau ua ua ntej rau kev pabcuam lub neej thiab kev ntseeg tau.
(1) Daim ntawv thov: tapered roller bearings yog tsim rau bearing radial thiab axial ua ke loads mas radial loads. Nws feem ntau yog siv ua khub nrog ob pawg ntawm cov kabmob. Nws yog tsuas yog siv rau kis tau tus mob qhov chaw xws li pem hauv ntej thiab nram qab hubs, active bevel gears, sib txawv, thiab reducers ntawm tsheb.
(2) Tso cai ceev: Nyob rau hauv cov ntaub ntawv 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, qhov txwv ceev ntawm 0.2 zaug yog qhov zoo dua.
(3) Permissible qaij lub kaum sab xis: tapered roller bearings feem ntau tsis tso cai rau tus ncej kom qaij txheeb ze rau lub tsev bore. Yog tias muaj inclination, qhov siab tshaj plaws inclination yuav tsum tsis pub tshaj 2 degrees.
(4) Tso cai rau qhov kub thiab txias: Nyob rau hauv cov xwm txheej ntawm cov kabmob ib txwm muaj, qhov kub thiab txias tsis kam ntawm lubricant thiab lubrication txaus, cov kabmob dav dav raug tso cai ua haujlwm ntawm qhov ntsuas kub ntawm -30 degree - 150 degree .
4. Kev txhim kho txoj kev ntawm tapered roller bearing
(1) Txoj kev txhim kho ntawm kev sib tw tapered cov menyuam bearing: thrust cylindrical cov menyuam bearing thiab thrust koob rau cov menyuam bearing yog tsim rau tsawg-ceev zaus. Thrust tapered roller bearings muaj qhov nrawm dua me ntsis dua li cov kabmob thrust nto. Thrust bearings yog feem ntau raug rau axial loads hauv cov rooj sib txoos thiab tau siv dav. Txawm hais tias thrust bearings raug ntsia thiab khiav.
(2) Yuav ua li cas cov iav thiab tapered roller bearings sib sau ua ke? Cov iav yuav tsum tau tsim nrog axial positioning cov 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. Lub preload ntawm lub xauv yuav tsum tau teem raws li cov kev cai ntawm kev siv.
(3) Yuav ua li cas rau nruab thiab kho qhov clearance ntawm tapered menyuam bearings? Feem ntau, tapered roller bearings tuaj yeem siv lub ntsej muag rau lub ntsej muag thiab rov qab rau sab nraub qaum. Cov pab pawg tshem tawm yuav tsum raug xaiv raws li qhov loj me uas koj xaiv thiab qhov raug xa mus los ntawm lub tshuab! Txoj kev hloov kho tuaj yeem ua tiav los ntawm nias thiab tso tawm.
