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

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

 

Inā ua ʻimi ʻoe i nā bearings ma ka pūnaewele, ua ʻike paha ʻoe i nā wehewehe huahana e pili ana i ka hoʻokō ʻana i nā kūlana ANSI, ISO, a i ʻole ASTM. Ua ʻike ʻoe he hōʻailona o ka maikaʻi nā kūlana - akā na wai i hana mai iā lākou, a he aha ke ʻano o ia mau mea?

 

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

 

Nā Kūlana ANSI

Aia ke keʻena nui o ka American National Standards Institute, a i ʻole ANSI, ma Wakinekona, DC. ʻO kona mau lālā e komo pū ana me nā kino honua, nā keʻena aupuni, nā hui, a me nā kānaka. Ua hoʻokumu ʻia i ka makahiki 1918 ma ke ʻano he American Engineering Standards Committee i ka wā i hui pū ai nā lālā o ka United Engineering Society a me nā Keʻena Kaua, Navy, a me Commerce o ke aupuni o ʻAmelika e hana i kahi hui kūlana.

ʻAʻole hana ʻo ANSI i nā kūlana loea ponoʻī. Akā, nānā ia i nā kūlana ʻAmelika a hoʻonohonoho iā lākou me nā kūlana o ka honua. Hōʻoia ia i nā kūlana o nā hui ʻē aʻe, e hōʻoia ana e ʻae like nā mea a pau o ka ʻoihana i ke ʻano o ka hopena o kahi kūlana i kā lākou huahana a me nā kaʻina hana. Hōʻoia wale ʻo ANSI i nā kūlana i manaʻo ʻia he kūpono a ākea.

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

He mau haneli mau kūlana e pili ana i ka pōpō a ANSI.

 

Nā Kūlana ISO

Ua wehewehe ka International Standards Organization (ISO) ma Switzerland i kāna mau kūlana ma ke ʻano he "ʻano hana e wehewehe ana i ke ala maikaʻi loa e hana ai i kekahi mea." He hui honua kūʻokoʻa ʻo ISO, ʻaʻole ia he aupuni, e hana ana i nā kūlana honua. He 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 hoʻohālikelike honua. I ka makahiki 1951, ua hana ʻo ISO i kāna kūlana mua, ʻo ISO/R 1:1951, nāna i hoʻoholo i ka mahana kuhikuhi no nā ana lōʻihi ʻoihana. Mai ia manawa, ua hana ʻo ISO i kahi kokoke i 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, ka hoʻomau, a me ka palekana o kā lākou huahana a me nā hana hana. Aia kekahi ala maʻamau ISO no ka hana ʻana i kahi kīʻaha kī!

Loaʻa iā ISO kahi kokoke i 200 mau kūlana bearing. ʻO nā haneli o kāna mau kūlana ʻē aʻe (e like me nā mea e pili ana i ke kila a me ka seramika) e hoʻopilikia pololei ʻole i nā bearings.

 

Nā Kūlana ASTM

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

Aia ke aʻa o ASTM ma nā alahao o ka Industrial Revolution. ʻO ke kūlike ʻole o nā alahao kila i hoʻokahe i nā alahao mua. I ka makahiki 1898, ua hoʻokumu ke kemika ʻo Charles Benjamin Dudley iā ASTM me kahi hui o nā ʻenekinia a me nā kānaka ʻepekema e ʻimi i kahi hopena no kēia pilikia weliweli. Ua hana lākou i kahi hoʻonohonoho maʻamau o nā kikoʻī no ke kila alahao. Ma luna o 125 mau makahiki mai kona hoʻokumu ʻia ʻana, ua wehewehe ʻo ASTM ma mua o 12,500 mau kūlana no ka nui o nā huahana, nā mea hana, a me nā kaʻina hana i nā ʻoihana mai nā metala maka a me ka petroleum a hiki i nā huahana mea kūʻai.

Hiki i kekahi ke hui pū me ASTM, mai nā lālā o ka ʻoihana a hiki i nā mea hoʻonaʻauao a me nā kākāʻōlelo. Hoʻokumu ʻo ASTM i nā kūlana kuʻikahi manawaleʻa. Hiki mai nā lālā i kahi ʻaelike hui (kuʻikahi) e pili ana i ke ʻano o kahi kūlana. Loaʻa nā kūlana no kekahi kanaka a ʻoihana paha e lawe (me ka manawaleʻa) e alakaʻi i kā lākou mau hoʻoholo.

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

 

Kōkua nā kūlana ANSI, ISO, a me ASTM iā ʻoe e kūʻai i nā bearings maikaʻi loa

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