ʻIke kumu no ke hali ʻana

Ma ke ʻano he ʻāpana koʻikoʻi o nā mīkini o kēia wā, nā mea e hāpai ana ua hoʻohana nui ʻia. Ua ʻike mākou a pau a ʻike nui a emi mai paha e pili ana i ia mea.

Nā Bearingsʻo ka maʻamau he apo o loko, he apo o waho, nā mea ʻōwili a me kahi pā. No nā bearings i sila ʻia, e hoʻohui i ka lubricant a me nā sila (a i ʻole nā ​​pale). ʻO ia ke ʻano o nā bearings.

Wahi a nā kūlana hana o ka bearing, hiki ke koho ʻia nā ʻano bearings like ʻole e hoʻokani maikaʻi i ka hana o ka bearing a hoʻolōʻihi i ke ola lawelawe o ka bearing. Pono mākou e noʻonoʻo i nā mea aʻe i ke koho ʻana i nā bearings:

ʻO ke kumu hoʻohālike bearing ma ke ʻano laulā he pre-code, he code kumu a me kahi post-code. Ma ke ʻano laulā, ʻo ka hōʻailona bearing wale nō e hōʻike ʻia e ka hōʻailona kumu. ʻO ke kumu hoʻohālike kumu ma ke ʻano laulā he ʻekolu mau ʻāpana, ke code ʻano, ke code nui a me ke code diameter o loko. ʻO ka post-code ka hoʻohana ʻana i nā leka a me nā helu e hōʻike i ke ʻano, ka hoʻomanawanui a me nā koi kūikawā o ka mea. Hoʻohana ʻia ke code prefix e hōʻike i nā ʻāpana liʻiliʻi o ka bearing, i hōʻike ʻia e nā leka.

 

1. Inoa code kumu

Hoʻohana ʻia ke code kumu e hōʻike i ke anawaena o loko, nā moʻo anawaena, nā moʻo laulā a me ke ʻano o ke bearing, ma ke ʻano maʻamau a hiki i ʻelima mau huahelu, penei:

1) Hōʻike ʻia ke anawaena o loko o ka bearing e ka huahelu mua mai ka ʻākau o ke code kumu.

ʻO ke anawaena o loko o ka bearing me ke anawaena o loko maʻamau o d=20~480mm he nui ia o 5, a ʻo kēia mau huahelu ʻelua e hōʻike ana i ka quotient o ka nui o ke anawaena o loko o ka bearing i puʻunaue ʻia e 5, e like me 04 ʻo ia hoʻi ʻo d=20mm; 12 ʻo ia hoʻi ʻo d=60mm a pēlā aku. No nā bearings me ke anawaena o loko o 10mm, 12mm, 15mm a me 17mm, ʻo nā code anawaena o loko he 00, 01, 02 a me 03. No nā bearings me ke anawaena o loko ma lalo o 10mm a ʻoi aku ma mua o 500mm, ua kuhikuhi ʻia ke ʻano hōʻike anawaena o loko, e ʻoluʻolu e nānā iā GB/T272-93.

 

2) ʻO ke anawaena o ka bearing (ʻo ia hoʻi, ke ʻano o nā loli i ke anawaena o waho a me ka laulā o ka bearing me ke ʻano like a me ke anawaena o loko like) e hōʻike ʻia e ka helu ʻekolu mai ka ʻākau o ke code kumu.

No ka laʻana, no nā bearings radial a me nā bearings thrust radial, hōʻike ʻo 0 a me 1 i ka moʻo māmā keu; hōʻike ʻo 2 i ka moʻo māmā; hōʻike ʻo 3 i ka moʻo waena; hōʻike ʻo 4 i kahi moʻo kaumaha. Hōʻike ʻia ka hoʻohālikelike ʻana o ka nui ma waena o ka moʻo ma ke kiʻi ma lalo nei. Koe wale nō ka moʻo māmā keu me 1, kūlike ka bearings thrust me ka hōʻike ʻana o ka bearing radial.

3) ʻO ka moʻo laulā o ka bearing (ʻo ia hoʻi, ke ʻano o nā loli i ka laulā o ka bearing me ke ʻano like, ke anawaena o loko a me ke anawaena) e hōʻike ʻia e ka huahelu ʻehā mai ka ʻākau o ke code kumu.

Ke hoʻohālikelike ʻia nā moʻo anawaena o nā moʻo laulā o ke Kiʻi 13-4 ma ke ʻano he moʻo 0 (moʻo maʻamau), ʻaʻole hiki ke hōʻailona ʻia ke code moʻo laulā O i loko o ke code no ka hapa nui o nā bearings, akā no nā bearings wili poepoe a me nā bearings wili tapered, pono e hōʻailona ʻia ke code moʻo laulā 0. ʻO nā code moʻo anawaena a me nā code moʻo laulā e kapa ʻia he mau code moʻo ana.

 

4) Hōʻike ʻia ke code ʻano bearing e ka huahelu ʻelima mai ka ʻākau o ke code kumu (no nā bearings roller cylindrical a me nā bearings roller nila, he leka ke code).

 

2. Leka uila

ʻO ke code post o ka bearing e hoʻohana i nā leka a me nā helu e hōʻike i ke ʻano, ka hoʻomanawanui a me nā koi kūikawā o ka mea. Nui nā ʻike o nā code post, a eia kekahi mau inoa code i hoʻohana pinepine ʻia.

1) ʻO ke code hoʻonohonoho kūloko e hōʻike i ke ʻano kūloko like ʻole o ke ʻano like o ka bearing, i hōʻike ʻia e nā leka i ukali ʻia e ke code kumu. No ka laʻana, ʻo nā bearings pōpō hoʻopili angular me nā kihi hoʻopili o 15°, 25° a me 40° ua hōʻike ʻia e C, AC a me B e hōʻike i ka ʻokoʻa o ke ʻano kūloko.

2) Ua māhele ʻia ke ʻano hoʻomanawanui o ka bearing i 2 mau ʻano, 4 mau ʻano, 5 mau ʻano, 6 mau ʻano, 6 mau ʻano a me 0 mau ʻano, he 6 mau ʻano, mai ke kiʻekiʻe a i ka haʻahaʻa, a ʻo kā lākou mau code he /PZ, /P4, /PS, /P6, /P6X a me /PO. Ma waena o nā papa hoʻomanawanui, pili wale ka papa 6X i nā bearings roller tapered; ʻO ka Papa 0 kahi papa maʻamau, ʻaʻole i hōʻailona ʻia ma ke code bearing huila.

3) Ua māhele ʻia ka moʻo hoʻokaʻawale radial bearing maʻamau i 1 hui, 2 hui, 0 hui, 3 hui, 4 hui a me 5 hui, he 6 hui ka huina, a ʻo ka hoʻokaʻawale radial mai ka liʻiliʻi a i ka nui. ʻO ka hoʻokaʻawale hui o kahi hui hoʻokaʻawale i hoʻohana pinepine ʻia, ʻaʻole i hōʻailona ʻia ma ke code bearing, a ʻo ke koena o nā hui hoʻokaʻawale i hōʻike ʻia e /CI, /CZ, /C3, /C4 a me /CS ma ke code bearing.

 

3. Kōkuhi mua

Hoʻohana ʻia ka hoʻolālā prefix o ka bearing e hōʻike i nā ʻāpana liʻiliʻi o ka bearing, i hōʻike ʻia e nā leka. No ka laʻana, hoʻohana ʻia ʻo L e hōʻike i ke apo hiki ke hoʻokaʻawale ʻia o kahi bearing hiki ke hoʻokaʻawale ʻia; Hōʻike ʻo K i nā mea ʻōwili a me nā ʻāpana cage o ka bearing, a pēlā aku.

 

Nui nā ʻano o nā bearings ʻōwili i nā hana kūpono, a ʻoi aku ka paʻakikī o nā code bearing pili. ʻO ke code i hoʻolauna ʻia ma luna nei ka ʻāpana maʻalahi loa a hoʻohana pinepine ʻia o ke code bearing, a hiki iā ʻoe ke ʻike a nānā i ka bearing i hoʻohana pinepine ʻia inā ʻoe e kamaʻāina me kēia ʻāpana o ke code. No ke ʻano code kikoʻī o nā bearings ʻōwili, e ʻoluʻolu e nānā iā GBT272.
