Cov qauv ntawm Precision Bearing Model Codes
Precision bearing qauv codes feem ntau yog alphanumeric cov hlua uas qhia cov ntaub ntawv muaj txiaj ntsig. Txawm hais tias cov tuam txhab sib txawv yuav muaj cov txheej txheem coding tshwj xeeb, feem ntau cov lej muaj ntau yam tseem ceeb: cov kabmob hom, qhov loj me, series, clearance, thiab lwm yam tshwj xeeb xws li lub tawb tsim thiab cov khoom siv. Ntawm no yog ib qho kev puas tsuaj ntawm cov khoom sib xws uas pom nyob rau hauv ib qho kev coj tus cwj pwm raug cai.
1. Hom kabmob
Thawj feem ntawm tus qauv code feem ntau yog sawv cev rau hom kabmob. Cov hom muaj xws li:
Sib sib zog nqus Groove Pob Bearings (6200 Series): Cov no muaj ib tug yooj yim tsim thiab haum rau high speeds thiab nruab nrab loads.
Angular Sib cuag Pob Bearings (7000 Series): Tsim kom haum rau axial loads nyob rau hauv ib qho kev taw qhia, cov bearings no yog siv nyob rau hauv daim ntawv thov uas yuav tsum tau high precision.
Cylindrical Cov Menyuam Bearings (NU Series): Zoo tagnrho rau hnyav radial loads, cov kabmob no tso cai rau kev ua haujlwm ceev dua.
Thrust Bearings (AX Series): Tsim los tswj axial loads, thrust bearings yog siv nyob rau hauv daim ntaub ntawv xws li tsheb kis tau tus mob.
2. Kev Tsim Qauv Loj
Qhov loj me me feem ntau ua raws li qhov taw qhia bearing. Cov lej no feem ntau suav nrog cov kabmob sab hauv txoj kab uas hla, sab nraud, thiab qhov dav. Piv txwv li, nyob rau hauv ib tug qauv code ntawm6204-2RS, '04' txhais tau hais tias cov kabmob muaj ib txoj kab uas hla ntawm 20 hli, sab nraud ntawm 47 hli, thiab qhov dav ntawm 14 hli.
3. Series Indication
Lub koob ntawm cov kabmob hais txog nws lub peev xwm thauj khoom thiab lub nplhaib puab tsim. Cov lej ntau dua feem ntau qhia tau tias muaj qhov tseeb siab dua lossis kev ntsuas kev thauj khoom. Piv txwv li, nyob rau hauv ib tug angular contact bearing, series yuav qhia tau lub kaum sab xis ntawm kev sib cuag; ib tug 70 series tej zaum yuav muaj ib tug 15-degree hu lub kaum sab xis, thaum lub 72 series tej zaum yuav muaj ib tug 30-degree kaum.
4. Qib Siab
Cov chav kawm kam rau ua qhia qhov tseeb ntawm cov kabmob. Cov chav kawm uas muaj xws li:
P0(Normal Precision)
P6(High Precision)
P5(Higher Precision)
P4(Super Precision)
Cov chav kawm no cuam tshuam tsis yog tsuas yog kev ua haujlwm ntawm cov kabmob tab sis kuj yog nws qhov tsim nyog rau kev siv ceev ceev lossis cov uas xav tau kev ua si tsawg.
5. Internal Clearance
Internal clearance yog qhov tseem ceeb hauv kev ua haujlwm ntawm precision bearings. Nws hais txog qhov chaw nruab nrab ntawm cov khoom dov thiab cov kev sib tw. Common classifications ntawm internal clearance muaj xws li:
C0: Ib txwm
C2: Txo
C3: Nce
C4: Nce nce
Xaiv qhov raug tshem tawm sab hauv yog qhov tseem ceeb rau cov ntawv thov sib txawv ntawm qhov kub, qhov hnyav, thiab ceev.
6. Cov yam ntxwv tshwj xeeb
Qee cov qauv code kuj suav nrog cov ntawv ntxiv uas qhia txog cov yam ntxwv tshwj xeeb, xws li:
ZZ los yog 2RS: Qhia tias muaj cov ntsaws ruaj ruaj los yog cov ntaub thaiv npog rau cov plua plav thiab cov roj nplaum tuav.
HT: Qhia txog qhov muaj peev xwm kub kub.
V: Qhia txog qee yam ntawm lubrication.
Cov yam ntxwv no tuaj yeem cuam tshuam rau cov kabmob kev ua haujlwm thiab kev ua haujlwm ntev.
Kev siv ntawm Precision Bearings
Precision bearings pom cov ntawv thov thoob plaws ntau qhov kev lag luam, txhua tus muaj cov kev xav tau tshwj xeeb rau kev ua tau zoo, durability, thiab precision. Nov yog qee qhov chaw tseem ceeb uas qhov precision bearings indispensable:
1. Aerospace
Hauv kev siv aerospace, precision bearings yuav tsum tiv taus huab cua, nrog rau kev hloov pauv kub thiab kev sib hloov ceev. Cov kabmob siv dav hlau siv dav hlau, tsaws iav mechanisms, thiab avionics feem ntau xav tau cov qauv nruj nruj, ua rau lawv xaiv qhov tseem ceeb rau kev nyab xeeb ntawm kev ya davhlau.
2. Automotive
Kev lag luam automotive siv precision bearings nyob rau hauv lub cav, kis tau tus mob, thiab lub log sib dhos. Raws li cov tsheb tau dhau los ua nyuaj nrog hybrid thiab hluav taws xob thev naus laus zis, qhov kev thov rau kev ua haujlwm siab tau nce siab. Cov bearings no yuav tsum ua tsis tau tsuas yog high speeds tab sis kuj tseem ceeb torque thiab load variations.
3. Kev tsim khoom
Hauv kev tsim khoom siv, precision bearings kom ua haujlwm du thiab ua haujlwm ntev. Nrog cov tshuab ua haujlwm ntawm kev kub ceev, cov kabmob muaj peev xwm txo qis kev sib txhuam thiab tswj xyuas qhov tseeb yog qhov tseem ceeb rau kev tsim khoom thiab qhov zoo ntawm cov khoom tsim.
4. Cov khoom siv kho mob
Precision bearings yog qhov tseem ceeb hauv cov khoom siv kho mob xws li MRI tshuab, cov cuab yeej phais neeg hlau, thiab lwm yam khoom siv kuaj mob. Cov ntawv thov no tsis tsuas yog siab precision tab sis kuj muaj kev ntseeg siab thiab kev ua tau zoo nyob rau hauv cov xwm txheej tsis muaj menyuam, ua tshwj xeeb cov kabmob tseem ceeb.
Xaus
Kev nkag siab txog cov qauv kev coj tus kheej cov lej yog qhov tseem ceeb rau cov kws tshaj lij thiab cov kws tshaj lij uas xav xaiv cov khoom tsim nyog rau lawv daim ntawv thov. Los ntawm kev paub txog cov qauv ntawm cov lej no, ib tus tuaj yeem txiav txim siab sai ntawm cov kabmob cov lus qhia, suav nrog hom, qhov loj me, qhov tseeb, kev tshem tawm, thiab cov yam ntxwv tshwj xeeb.
Nyob rau hauv lub ntiaj teb no qhov kev ua tau zoo ntawm cov tshuab thiab cov cuab yeej yog qhov tseem ceeb, precision bearings ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev ua haujlwm zoo thiab kev ntseeg siab. Raws li kev lag luam txuas ntxiv mus txuas ntxiv thiab xav tau nce ntxiv, qhov tseem ceeb ntawm kev txhais cov qauv coj tus qauv kom raug tsuas yog loj hlob, kom ntseeg tau tias cov ntawv thov ua tiav lawv cov qauv kev ua tau zoo.
Kev nqis peev rau lub sijhawm kom paub txog tus kheej nrog cov lej no tsis tsuas yog txuag lub sijhawm hauv kev xaiv cov khoom lag luam tab sis tseem txhim kho kev ua haujlwm tag nrho kev ntseeg siab, thaum kawg ua rau kev txhim kho cov khoom lag luam thiab kev tsim kho tshiab hauv ntau yam haujlwm.
