Aia 4 mau ʻano o nā hua hex i hoʻohana mau ʻia:
1. GB/T 41-2016 “Kano 1 Hex Nut Papa C”
2. GB/T 6170-2015 “Nut Hex Type 1”
3. GB/T 6175-2016 “Nati Hex ʻAno 2”
4. GB/T 6172.1-2016 “Hexagon Thin Nut”
ʻO nā ʻokoʻa nui ma waena o nā nati ʻehā i hoʻohana pinepine ʻia e like me kēia:
1. He ʻokoʻa ke kiʻekiʻe o ka nut:
E like me nā ʻōlelo a ka National Standard GB / T 3098.2-2015 "Mechanical Properties of Fasteners Nuts", aia ʻekolu ʻano o nā kiʻekiʻe o nā nut:
——Ke ʻano 2, nati kiʻekiʻe: kiʻekiʻe liʻiliʻi mmin≈0.9D a i ʻole >0.9D;
——Ke ʻano 1, nati maʻamau: kiʻekiʻe liʻiliʻi mmin≈0.8D;
——Ke ʻano 0, nati lahilahi: kiʻekiʻe haʻahaʻa 0.45D≤mmin<0.8D.
'Ōlelo Aʻo: ʻO D ka anawaena inoa o ka milo nut.
Ma waena o nā hua ʻehā i hoʻohana mau ʻia:
ʻO GB / T 41-2016 "Type 1 Hex Nut Grade C" a me GB / T 6170-2015 "Type 1 Hex Nut" he Type 1 maʻamau nati, a ʻo ke kiʻekiʻe haʻahaʻa o ka nati he mmin≈0.8D.
ʻO GB / T 6175-2016 "Type 2 Hex Nuts" kahi ʻano 2 kiʻekiʻe nati, a ʻo ke kiʻekiʻe haʻahaʻa o ka nati he mmin≥0.9D.
ʻO GB/T 6172.1-2016 “Hexagon Thin Nut” he ʻano 0 lahilahi nati, a ʻo ke kiʻekiʻe haʻahaʻa o ka nati he 0.45D≤mmin＜0.8D.
2. Nā māka huahana like ʻole:
Hoʻokaʻawale ʻia nā māka huahana o nā nati i nā māka A, B a me C.Hoʻoholo ʻia nā māka huahana e ka nui hoʻomanawanui.ʻO kahi māka ka pololei loa a ʻo ka māka C ka mea liʻiliʻi loa.
ʻO GB/T 41-2016 "ʻAno 1 Hexagon Nuts Grade C" e wehewehe i nā hua me ka pololei o ka papa C.
ʻO GB / T 6170-2015 "Type 1 Hexagonal Nuts", GB / T 6175-2016 "Type 2 Hexagonal Nuts" a me GB / T 6172.1-2016 "Hexagonal Thin Nuts" e kuhikuhi i nā hua me ka helu A a me ka helu B.
Ma GB / T 6170-2015 "Type 1 Hexagonal Nuts", GB / T 6175-2016 "Type 2 Hexagonal Nuts" a me GB / T 6172.1-2016 "Hexagonal Thin Nuts", Hoʻohana ʻia ʻo Grade A no nā hua me D≤16mm;Hoʻohana ʻia ka papa B no nā nati me D>16mm.
E like me ke kūlana aupuni GB / T 3103.1-2002 "Fastener Tolerance Bolts, Screws, Studs and Nuts", ʻo ka māka hoʻomanawanui o ka pae o loko o ka pae A-level a me B-level precision nuts "6H";ʻO ka pae hoʻomanawanui o ke kaula kūloko ʻo "7H";ʻokoʻa nā māka hoʻomanawanui o nā ʻāpana ʻē aʻe o nā nati e like me ka pololei o nā māka A, B a me C.
3. Nā māka like ʻole o nā waiwai mechanical
E like me nā ʻōlelo o ka National Standard GB / T 3098.2-2015 "Mechanical Properties of Fastener Nuts", ʻo nā bolts i hana ʻia me ke kila kalapona a me ke kila kila he 7 mau ʻano o nā māka hana mechanical ma lalo o ke ʻano o kahi ʻano kaiapuni o 10 ° C a 35. °C.ʻO lākou he 04, 05, 5, 6, 8, 10, 12.
E like me nā ʻōlelo o ka National Standard GB / T 3098.15-2014 "Mechanical Properties of Fasteners Stainless Steel Nuts", i ka wā o ke ʻano o ke kaiapuni ʻo 10 ° C a 35 ° C, ua kuhikuhi ʻia nā māka hana o nā nati i hana ʻia me ke kila kila. :
ʻO nā nati i hana ʻia me ke kila kila austenitic (me nā pūʻulu A1, A2, A3, A4, A5) he 50, 70, 80 a me 025, 035, 040. ʻāpana, ʻo ka ʻāpana mua e hōʻailona i ka hui kila, a ʻo ka ʻāpana ʻelua e hōʻailona i ka pae hana, hoʻokaʻawale ʻia e nā kaha, e like me A2-70, ka mea like ma lalo)
ʻO nā hua i hana ʻia me ke kila kila martensitic o ka hui C1 he mau māka waiwai mechanical o 50, 70, 110 a me 025, 035, 055;
ʻO nā hua i hana ʻia me ke kila kila martensitic o ka hui C3 loaʻa nā waiwai mechanical o 80 a me 040;
ʻO nā hua i hana ʻia me ke kila kila martensitic o ka hui C4 he mau māka waiwai mechanical o 50, 70 a me 025, 035.
ʻO nā nati i hana ʻia me ka hui F1 ferritic stainless steel he mau māka waiwai mechanical o 45, 60 a me 020, 030.
E like me nā ʻōlelo o ke kūlana aupuni GB / T 3098.10-1993 "Nā Mea Mechanical of Fasteners - Bolts, Screws, Studs and Nuts Made of Non-ferrous Metals":
ʻO nā hua i hana ʻia me ke keleawe a me ke keleawe he mau māka hana mechanical: CU1, CU2, CU3, CU4, CU5, CU6, CU7;
ʻO nā hua i hana ʻia me ka alumini a me nā alumini alumini he mau māka hana mechanical: AL1, AL2, AL3, AL4, AL5, AL6.
ʻO ke kūlana aupuni GB/T 41-2016 "Type 1 Hexagon Nut Grade C" pili i ka papa C hexagon nuts me nā kiko kikoʻī M5 ~ M64 a me ka pae hana 5.
ʻO ka pae aupuni GB / T 6170-2015 "Type 1 Hexagon Nut" pili i nā kikoʻī kikoʻī M1.6 ~ M64, nā māka hana he 6, 8, 10, A2-70, A4-70, A2-50, A4-50. , CU2 , CU3 a me AL4 papa A a me B hex nati.
ʻO ke kūlana aupuni GB/T 6175-2016 "Type 2 Hexagon Nuts" pili i ka papa A a me ka papa B hexagon bolts me nā kiko kiko M5~M36 a me nā māka hana 10 a me 12.
ʻO ka pae aupuni GB / T 6172.1-2016 "Hexagon Thin Nut" pili i nā kikoʻī kikoʻī M1.6 ~ M64, nā helu hana he 04, 05, A2-025, A2-035, A2-50, A4-035, CU2, CU3 a me AL4 papa A a me B hexagonal nati lahilahi.
Hōʻike ʻia ke anawaena nominal e pili ana i ke ʻano nut a me ka pae hana ma ka papa ma lalo.
Pono e hoʻohana ʻia nā nati maʻamau (ʻano 1) a me nā nati kiʻekiʻe (ʻano 2) i hana ʻia me ke kila kalapona a me ke kila kila me nā mea hoʻopaʻa wili waho ma ka papa ma lalo nei, a hiki i nā nati me nā pae ikehu hana kiʻekiʻe ke pani i nā nati me nā māka haʻahaʻa haʻahaʻa.
ʻO nā nati maʻamau (ʻano 1) ka mea i hoʻohana nui ʻia.
Hoʻohana maʻamau ʻia nā nati kiʻekiʻe (ʻano 2) i nā pilina e pono ai ka wehe pinepine ʻana.
He haʻahaʻa ko nā nati lahilahi (Type 0) ma mua o nā nati maʻamau a lōʻihi paha, no laila ʻaʻole pono lākou e hoʻolālā ʻia no nā noi anti-tripping.
Hoʻohana maʻamau ʻia nā nati lahilahi (ʻano 0) i loko o nā hale kūʻē i ka wehe ʻana i nā nati pālua.
