Cov kabmob ruaj khov yog ib lub nplhaib-zoo li ib feem ntawm cov kabmob thrust dov nrog ib lossis ob peb txoj kev sib tw.Taag-kawg bearings siv radial bearings uas tuaj yeem tiv taus ua ke (radial thiab longitudinal) loads.Cov bearings no muaj xws li: sib sib zog nqus groove pob bearings, ob kab los yog khub ib kab angular hu rau pob bearings, self-aligning pob bearings, kheej kheej cov menyuam bearings, matched tapered menyuam bearings, NUP cylindrical menyuam bearings los yog cov neeg uas muaj HJ angular rings NJ hom cylindrical menyuam bearings .
Tsis tas li ntawd: kev npaj cov kabmob ntawm qhov kawg tuaj yeem suav nrog kev sib xyaw ntawm ob lub kabmob:
1. Radial bearings uas tsuas muaj peev xwm dais radial loads, xws li cylindrical roller bearings nrog ib lub nplhaib tsis muaj tav.
2. Muab axial positioning bearings, xws li sib sib zog nqus groove pob bearings, plaub-point contact pob bearings los yog ob-txoj kev thrust bearings.
Cov kabmob uas siv rau qhov chaw axial yuav tsum tsis txhob siv rau qhov chaw radial, thiab feem ntau muaj qhov me me radial clearance thaum ntsia ntawm lub rooj zaum bearing.
Nws muaj ob txoj hauv kev los hloov kho cov thermal hloov ntawm cov av nkos bearing ncej.Ua ntej, siv cov kabmob uas tsuas yog dais radial loads thiab tuaj yeem tso cai rau axial hloov mus rau hauv cov kabmob.Cov kabmob no muaj xws li CARE toroidal cov menyuam bearings, koob rau cov menyuam bearings thiab cov kabmob cylindrical menyuam kabmob uas tsis muaj tav ntawm lub nplhaib.Lwm txoj hauv kev yog siv cov kabmob radial nrog lub me me radial clearance thaum ntsia ntawm lub rooj zaum bearing kom lub nplhaib sab nraud tuaj yeem txav mus los ntawm qhov kev taw qhia axial.
Positioning txoj kev ntawm taag bearing
1. Xauv txiv ntoo txoj hauv kev:
Thaum txhim kho cov kabmob puab lub nplhaib nrog kev cuam tshuam haum, feem ntau ib sab ntawm lub nplhaib sab hauv yog tawm tsam lub xub pwg nyom ntawm tus ncej, thiab sab nraud feem ntau yog kho nrog lub ntsuas phoo (KMT lossis KMT A series).Cov bearings nrog tapered qhov yog ncaj qha mounted rau ntawm tapered journal, feem ntau tsau rau ntawm ncej nrog ib tug xauv txiv ntseej.
2. Spacer positioning method:
Nws yog qhov yooj yim los siv spacers lossis spacers nruab nrab ntawm cov kabmob rings lossis nruab nrab ntawm cov kabmob rings thiab cov khoom nyob ib sab: es tsis txhob siv lub xub pwg nyom lossis lub xub pwg nyom.Nyob rau hauv cov ntaub ntawv no, qhov ntev thiab cov duab tolerances kuj siv rau lwm yam.
3. Qhov chaw ntawm cov kauj ruam ncej tes tsho:
Lwm txoj kev ntawm bearing axial positioning yog siv stepped bushings.Cov bushings no tshwj xeeb tshaj yog haum rau precision bearing kev npaj.Piv nrog threaded xauv ceev, lawv muaj tsawg runout thiab muab ntau dua qhov tseeb.Stepped bushings feem ntau yog siv rau ultra-high-speed spindles, rau cov tsoos locking li tsis tuaj yeem muab qhov tseeb txaus.
4. Tsau kawg cap positioning txoj kev:
Thaum txhim kho lub nplhaib sab nrauv nrog kev cuam tshuam haum, feem ntau ib sab ntawm lub nplhaib sab nraud yog tiv thaiv lub xub pwg ntawm lub rooj zaum bearing, thiab sab nraud yog tsau nrog lub hau kawg.Lub hau kawg ruaj khov thiab nws cov ntsia hlau kho muaj qhov cuam tshuam tsis zoo rau cov duab thiab kev ua haujlwm ntawm cov kabmob hauv qee kis.Yog hais tias phab ntsa thickness ntawm lub rooj zaum bearing thiab lub qhov ntsia hlau me me dhau, los yog cov ntsia hlau tau nruj heev, lub nplhaib sab nrauv yuav raug deformed.Qhov sib dua ISO loj series 19 series muaj qhov cuam tshuam rau hom kev puas tsuaj ntau dua li 10 series lossis hnyav dua.
Installation cov kauj ruam ntawm taag bearing
1. Ua ntej txhim kho cov kabmob ntawm tus ncej, koj yuav tsum xub thaij duab ntawm tus pin kho uas kho cov kabmob lub tsho, thiab tib lub sijhawm polish lub npoo ntawm cov ntawv xov xwm kom du thiab huv, thiab siv roj rau hauv phau ntawv xov xwm kom tsis txhob xeb. thiab lubricate (cia cov kabmob tig me ntsis ntawm tus ncej).
2. Siv cov roj lubricating rau ntawm qhov chaw sib txuas ntawm cov kabmob thiab cov kabmob: Muab ob-kab tapered roller bearing rau hauv lub rooj zaum bearing, tom qab ntawd muab cov kabmob sib dhos thiab cov kabmob ntawm lub rooj zaum ua ke, thiab thawb nws mus rau qhov yuav tsum tau ua. txoj hauj lwm rau installation.
3. Tsis txhob zawm cov bolts uas kho lub rooj zaum bearing, thiab ua kom cov kabmob vaj huam sib luag tig hauv lub rooj zaum bearing.Kuj nruab cov kabmob thiab lub rooj zaum ntawm qhov kawg ntawm tib lub ncej, tig lub ncej ob peb zaug, thiab cia cov kabmob ruaj khov tuaj yeem pom nws txoj haujlwm.Tom qab ntawd ceev cov kabmob lub rooj zaum bolts.
4. Nruab lub tes tsho eccentric.Ua ntej muab lub tes tsho eccentric rau ntawm cov kauj ruam eccentric ntawm lub tes tsho sab hauv ntawm cov kabmob, thiab ceev nws los ntawm txhais tes nyob rau hauv cov kev taw qhia ntawm kev sib hloov ntawm ncej, thiab ces ntxig rau lub me me pas nrig rau hauv los yog tawm tsam counterbore ntawm lub tes tsho eccentric.Ntaus tus pas hlau me me nyob rau hauv kev coj ntawm kev sib hloov ntawm lub ncej.Hlau rods ua rau lub tes tsho eccentric ntsia kom ruaj khov, thiab tom qab ntawd nruj lub hexagon socket screws ntawm lub tes tsho eccentric.
Cov yam ntxwv cuam tshuam rau kev coj tus kheej zoo
1. Nyob rau tib lub sijhawm ntawm kev tsim qauv thiab kev ua haujlwm siab, yuav muaj lub neej ntev dua.Bearing manufacturing yuav dhau los ntawm ntau cov txheej txheem ntawm forging, kho cua sov, tig, sib tsoo thiab sib dhos.Lub rationality, kev nce qib thiab kev ruaj ntseg ntawm kev kho mob kuj yuav cuam tshuam rau lub neej kev pab cuam ntawm cov kabmob.Cov kabmob kev kho cua sov thiab cov txheej txheem sib tsoo raug cuam tshuam, thiab cov khoom lag luam zoo feem ntau cuam tshuam ncaj qha rau qhov tsis ua haujlwm ntawm cov kabmob.Nyob rau hauv xyoo tas los no, cov kev tshawb fawb ntawm qhov deterioration ntawm bearing nto txheej tau pom tias cov txheej txheem sib tsoo yog ze ze rau cov kabmob nto zoo.
2. Kev cuam tshuam ntawm metallurgical zoo ntawm cov khoom siv bearing yog qhov tseem ceeb hauv kev ua tsis tiav thaum ntxov ntawm cov kabmob dov.Nrog rau kev nce qib ntawm kev siv tshuab metallurgical (xws li bearing steel, nqus degassing, thiab lwm yam), cov khoom siv raw khoom tau zoo dua qub.Qhov kev faib ua feem ntawm cov khoom siv raw khoom zoo hauv kev tsom xam tsis ua haujlwm tau poob qis, tab sis nws tseem yog ib qho tseem ceeb ntawm cov kabmob tsis ua haujlwm.Txawm hais tias qhov kev xaiv tsim nyog tseem yog ib qho kev ntsuas tsis ua haujlwm uas yuav tsum tau txiav txim siab.
3. Tom qab cov kabmob raug teeb tsa, txhawm rau txheeb xyuas seb qhov kev teeb tsa puas raug, nws yog qhov yuav tsum tau nqa tawm kev kuaj xyuas.Cov tshuab me tuaj yeem tig los ntawm tes kom paub meej tias lawv tig tau zoo.Cov khoom kuaj xyuas muaj xws li kev ua haujlwm tsis raug vim yog txawv teb chaws, nti, indentation, tsis ruaj khov torque vim kev txhim kho tsis zoo thiab kev ua haujlwm tsis zoo ntawm lub rooj zaum mounting, ntau torque vim me me heev clearance, installation yuam kev, thiab seal kev sib txhuam, thiab lwm yam. Tos.Yog tias tsis muaj qhov txawv txav, nws tuaj yeem txav mus los pib lub zog ua haujlwm.
Yog tias cov kabmob muaj qhov tsis ua haujlwm loj vim qee qhov laj thawj, cov kabmob yuav tsum raug tshem tawm kom paub qhov ua rau cua sov;Yog hais tias tus bearing yog rhuab nrog suab nrov, nws yuav yog hais tias cov bearing cover yog rubbing tiv thaiv ncej los yog lub lubrication yog qhuav.Tsis tas li ntawd, lub nplhaib sab nraud ntawm cov kabmob tuaj yeem txav los ntawm tes kom nws tig.Yog tias tsis muaj qhov xoob thiab kev sib hloov yog du, cov kabmob yog qhov zoo;Yog hais tias muaj looseness los yog astringency thaum lub sij hawm tig, nws qhia tau hais tias cov bearing puas lawm.Nyob rau lub sijhawm no, koj yuav tsum txheeb xyuas ntxiv thiab tshawb xyuas tus account.Vim li cas thiaj txiav txim siab seb cov kabmob tuaj yeem siv tau.
