He aha nā kūlana ANSI, ISO, a me ASTM no nā bearings?

ʻO nā kūlana ʻenehana, e like me nā maʻamau ASTM no nā bearings e kuhikuhi ana i ke ʻano mea kila e hoʻohana ai, kōkua i nā mea hana e hana i kahi huahana kūlike.

 

Inā ʻimi ʻoe i nā bearings ma ka pūnaewele, ua ʻike paha ʻoe i nā wehewehe huahana e pili ana i ka hālāwai ʻana i nā kūlana ANSI, ISO, a i ʻole ASTM. Ua ʻike ʻoe he hōʻailona o ka maikaʻi nā maʻamau - akā ʻo wai ka mea i hele mai me lākou, a he aha ke ʻano?

 

Kōkua nā kūlana ʻenehana i nā mea hana a me nā mea kūʻai aku. Hoʻohana nā mea hana iā lākou e hana a hoʻāʻo i nā mea a me nā huahana ma ke ala kūpono loa. Hoʻohana nā mea kūʻai aku iā lākou e hōʻoia i ka loaʻa ʻana o ka maikaʻi, nā kikoʻī, a me ka hana a lākou i noi ai.

 

NA KUMU ANSI

ʻO ka American National Standards Institute, a i ʻole ANSI, aia ma Wakinekona, DC. Aia kona mau lālā i nā hui honua, nā hui aupuni, nā hui, a me nā kānaka. Ua hoʻokumu ʻia i ka makahiki 1918 ma ke ʻano he Kōmike Kūʻai ʻAmelika Hui Pū ʻIa i ka wā i hui pū ai nā lālā o ka United Engineering Society a me nā keʻena aupuni o ke Kaua, Navy, a me Kālepa e hoʻokumu i kahi hui kūlana.

ʻAʻole hana ʻo ANSI i nā kūlana ʻenehana ponoʻī. Akā, mālama ia i nā kūlana ʻAmelika a hoʻonohonoho iā lākou me nā kūlana honua. Hāʻawi ia i nā kūlana o nā hui ʻē aʻe, e hōʻoia i ka ʻae ʻana o nā mea a pau o ka ʻoihana i ka hopena o kahi maʻamau i kā lākou huahana a me nā kaʻina hana. ʻAe wale ʻo ANSI i nā kūlana i manaʻo ʻia he kūpono a hāmama.

Ua kōkua ʻo ANSI i ka loaʻa ʻana o ka International Organization for Standardization (ISO). ʻO ia ka ʻelele ISO mana o ʻAmelika Hui Pū ʻIa.

He mau haneli e pili ana i ka lawe ʻana i ka pōleʻa ma ANSI.

 

NA KUMU ISO

Ua wehewehe ʻo Swiss-based International Standards Organization (ISO) i kāna mau maʻamau ma ke ʻano he "pola e wehewehe ana i ke ala maikaʻi loa e hana ai i kekahi mea." He hui kūʻokoʻa kūʻokoʻa ʻo ISO, ʻaʻole aupuni i hana i nā kūlana honua. ʻO 167 mau hui kūlana aupuni, e like me ANSI, he mau lālā o ISO. Ua hoʻokumu ʻia ʻo ISO i ka makahiki 1947, ma hope o ka hui ʻana o nā ʻelele mai 25 mau ʻāina e hoʻolālā i ka wā e hiki mai ana o ka standardization honua. I ka makahiki 1951, ua hana ʻo ISO i kāna maʻamau mua, ISO/R 1:1951, nāna i hoʻoholo i ka mahana kuhikuhi no nā ana lōʻihi o ka ʻoihana. Mai ia manawa, ua hana ʻo ISO ma kahi o 25,000 mau kūlana no kēlā me kēia kaʻina hana, ʻenehana, lawelawe, a me ka ʻoihana. Kōkua kāna mau kūlana i nā ʻoihana e hoʻonui i ka maikaʻi, hoʻomau, a me ka palekana o kā lākou huahana a me nā hana hana. Aia kekahi ala maʻamau ISO e hana ai i kīʻaha kī!

Loaʻa iā ISO ma kahi o 200 mau kūlana lawe. ʻO nā haneli o kāna mau kūlana ʻē aʻe (e like me nā mea e pili ana i ke kila a me ka ceramic) e hoʻopili pololei i nā bearings.

 

NA PALAPALA ASTM

Ke kū nei ʻo ASTM no ka American Society for Testing and Materials, akā ʻo ka hui ʻo Pennsylvania i kēia manawa ʻo ASTM International. Ho'ākāka ia i nā kūlana ʻenehana no nā ʻāina a puni ka honua.

Loaʻa iā ASTM kona mau aʻa i nā ala kaʻa o ka Industrial Revolution. ʻO ka like ʻole o nā kaʻa kila i haki mua nā ala kaʻaahi. I ka makahiki 1898, ua hoʻokumu ʻo chemist Charles Benjamin Dudley i ka ASTM me kahi hui o nā ʻenekinia a me nā ʻepekema e ʻimi i kahi hopena i kēia pilikia pilikia. Ua hana lākou i nā kikoʻī maʻamau no ke kila alahao. Ma luna o nā makahiki 125 mai kona hoʻokumu ʻia ʻana, ua wehewehe ʻo ASTM ma mua o 12,500 mau kūlana no ka nui o nā huahana, nā lako, a me nā kaʻina hana i nā ʻoihana mai nā metala maka a me ka ʻaila a i nā huahana mea kūʻai aku.

Hiki i nā mea a pau ke komo i ka ASTM, mai nā lālā o ka ʻoihana a i nā mea hoʻonaʻauao a me nā mea aʻoaʻo. Hoʻokumu ʻo ASTM i nā maʻamau ʻae like ʻole. Hele nā ​​lālā i kahi ʻaelike hui (consensus) e pili ana i ke ʻano o ka maʻamau. Loaʻa nā maʻamau no kēlā me kēia kanaka a ʻoihana paha e hoʻohana (ma ka manawaleʻa) e alakaʻi i kā lākou hoʻoholo.

Loaʻa iā ASTM ma mua o 150 mau maʻamau e pili ana i ka pōleʻa a me nā pepa symposium.

 

ʻO ANSI, ISO, A me ASTM STANDARDS KOKUA iā ʻoe e kūʻai i nā bearing maikaʻi loa

Hoʻopaʻa nā maʻamau ʻenehana iā ʻoe a me kahi mea hana bearing e ʻōlelo ana i ka ʻōlelo like. Ke heluhelu ʻoe ua hana ʻia kahi bearing mai SAE 52100 chrome steel, hiki iā ʻoe ke nānā i ka maʻamau ASTM A295 e ʻike pono pehea i hana ʻia ai ke kila a me nā mea i loko. Inā ʻōlelo ka mea hana ʻo kāna mau ʻāpana ʻōwili lipi i nā ana i kuhikuhi ʻia e ISO 355:2019, ʻike maopopo ʻoe i ka nui āu e loaʻa ai. ʻOiai hiki i nā kūlana ʻenehana ke ʻano nui, maikaʻi, ʻenehana, he mea pono lākou no ke kamaʻilio ʻana me nā mea hoʻolako a hoʻomaopopo i ka maikaʻi a me nā kikoʻī o nā ʻāpana āu e kūʻai ai.ʻIke hou aku, E ʻoluʻolu e kipa i kā mākou pūnaewele: www.cwlbearing.com
