Kodi Mungawerenge Bwanji Manambala a Bearing?

Anthu atsopano omwe amalowa mu bearing nthawi zambiri amasokonezeka ndi manambala ndi zilembo zingapo. Kwenikweni,chogwiriraManambala si achilendo; ndi gulu la "ma code ozindikiritsa" okonzedwa. Mukangomvetsa malamulo oyambira, mutha kudziwa mwachangu mtundu, kukula, ndi mawonekedwe a mtundu uliwonse wa bearing model.

 

Khodiyi ili ndi magawo atatu, ndipo gawo lililonse lili ndi chidziwitso chapadera.

 

YathunthuchogwiriraKawirikawiri code imakhala ndi magawo atatu: prefix, base code, ndi suffix.

 

Chiyambi nthawi zambiri chimasonyeza kulondola kwa chifaniziro kapena kutseguka kwa chifanizirocho, ndi zina zotero; khodi yoyambira ndi gawo lofunikira, lomwe lili ndi mtundu wa chifanizirocho, kukula kwake, ndi chidziwitso cha m'mimba mwake wamkati; chifanizirocho chimapereka tsatanetsatane wokhudza kapangidwe ka mkati, njira yotsekera, zinthu za m'khola, ndi zina zotero.

 

Chofala kwambirichogwiriraMa model nthawi zambiri amasiya mawu oyamba, makamaka poyang'ana kwambiri ma code oyambira ndi owonjezera.

 

Khodi yoyambira ndi maziko:

 

Khodi yoyambira nthawi zambiri imakhala ndi magawo atatu: khodi yamtundu, khodi ya mndandanda wa kukula, ndi khodi yamkati mwa mainchesi.

 

Mwachitsanzo, 6204 yodziwika bwino:

 

Nambala yoyamba "6" ikuyimira mtundu, kusonyeza mpira wozungulira mozama;

 

Manambala achiwiri "2" ndi a mndandanda wa kukula, kusonyeza m'lifupi ndi m'mimba mwake wa chimbalangondocho;

 

Manambala awiri omaliza "04" akuyimira m'mimba mwake wamkati.

 

Tiyeni tiwone ma code ena ofala:

 

Kuyambira ndi 3: Ma tapered roller bearing, monga 30208;

 

Kuyambira ndi N: Mabearing a cylindrical roller, monga N2210.

 

Kukumbukira mtundu wa code kumakupatsani mwayi wodziwa mwachangu gulu lomwe bearing ndi la.

 

Ma code amkati mwa diameter amatsatira dongosolo; kukumbukira kukumbukira mnemonic kumapangitsa kuti zikhale zosavuta.

 

Ma code a m'mimba mwake wamkati nthawi zambiri amakhala osokoneza, koma pali njira yowerengera yokhazikika.

 

Pa mainchesi amkati pakati pa 10 ndi 17 mm, maubwenzi ofanana ndi awa:

 

00 = 10 mm

 

01 = 12 mm

 

02 = 15 mm

 

03 = 17 mm

 

Pa mainchesi amkati pakati pa 20 ndi 480 mm, ingochulukitsani manambala awiri omaliza ndi 5. Mwachitsanzo, 04 ikuyimira 20mm, 08 ikuyimira 40mm, ndipo 10 ikuyimira 50mm.

 

Potsatira lamuloli, m'mimba mwake wamkati wa 6204 ndi 4×5=20mm, ndipo m'mimba mwake wamkati wa 30208 ndi 8×5=40mm, zomwe zimafotokoza bwino.

 

Kumvetsetsa tsatanetsatane wa mawu ofotokozera; kuzindikira zizindikiro zofala.

 

Ma suffix marks amawonjezera kapangidwe kake ndi magwiridwe antchito a bearing. Zizindikiro zodziwika bwino ndi izi:

 

Z, RZ, RS: Sonyezani mtundu wa chisindikizo kapena chivundikiro cha fumbi;

 

C1~C5: Sonyezani kukula kwa malo olowera; chiwerengero chikakhala chachikulu, malo olowerawo amakhala aakulu;

 

P0~P6: Sonyezani kalasi yolondola; kalasi ikakwera, kulondola kwake kumakwera;

 

Q, M, L, N: Kawirikawiri zimagwirizana ndi zinthu kapena kapangidwe ka khola.

 

Mawu owonjezera awa, ngakhale afupiafupi, amakhudza mwachindunji zochitika zomwe zimagwiritsidwa ntchito pa bearing ndipo sanganyalanyazidwe panthawi yogula ndi kusintha.

 

Dziwani mwachangu mtundu wa bere ndi nambala ya chitsanzo.

 

KumvetsetsachogwiriraMakhalidwe amenewa amaphatikizapo magawo atatu: choyamba, kuyang'ana mtundu; chachiwiri, kuyang'ana kukula ndi m'mimba mwake wamkati; ndipo potsiriza, kuyang'ana tsatanetsatane mu suffix.

 

Mwachitsanzo, kuona 6204 kumakuuzani kuti ndi bere lokhala ndi mpata waukulu wokhala ndi mainchesi amkati a 20mm; kuona 30208 kumakuuzani kuti ndi bere lozungulira lokhala ndi mainchesi amkati a 40mm. Mukadziwa bwino malamulo awa, mutha kuzindikira mitundu yosiyanasiyana mwachangu ndipo simungasokonezedwenso ndi manambala angapo.
