Hariho ubwoko 4 bwimbuto zikoreshwa cyane:
1. GB / T 41-2016 “Ubwoko bwa 1 Hex Nut Grade C”
2. GB / T 6170-2015 “Ubwoko bwa 1 Hex Nut”
3. GB / T 6175-2016 “Ubwoko bwa 2 Hex Nuts”
4. GB / T 6172.1-2016 “Hexagon Thin Nut”
Itandukaniro nyamukuru hagati yine zikoreshwa cyane ni izi zikurikira:
1. Uburebure bwimbuto buratandukanye:
Ukurikije ibivugwa mu rwego rwigihugu GB / T 3098.2-2015 “Ibyiza bya mashini byimbuto za Fasteners”, hari ubwoko butatu bwuburebure bwimbuto:
—— Ubwoko bwa 2, ibinyomoro birebire: uburebure buke mmin≈0.9D cyangwa> 0.9D;
—— Ubwoko bwa 1, ibinyomoro bisanzwe: uburebure buke mmin≈0.8D;
—— Andika 0, umutobe muto: uburebure buke 0.45D≤mmin <0.8D.
Icyitonderwa: D ni diameter nominal yumutwe wimbuto.
Muri bine byavuzwe haruguru bikunze gukoreshwa:
GB / T 41-2016 “Ubwoko bwa 1 Hex Nut Grade C” na GB / T 6170-2015 “Ubwoko bwa 1 Hex Nut” ni ubwoko bwa 1 busanzwe, kandi uburebure buke bwimbuto ni mmin≈0.8D.
GB / T 6175-2016 “Ubwoko bwa 2 Hex Nuts” ni ubwoko bwa 2 bwimbuto ndende, kandi uburebure buke bwimbuto ni mmin≥0.9D.
GB / T 6172.1-2016 "Hexagon Thin Nut" ni ubwoko 0 buto buto, kandi uburebure buke bwimbuto ni 0.45D≤mmin ＜ 0.8D.
2. Ibyiciro bitandukanye byibicuruzwa:
Ibiciro byibicuruzwa byimbuto bigabanijwemo amanota A, B na C.Ibyiciro byibicuruzwa bigenwa nubunini bwo kwihanganira.Urwego nukuri neza na C urwego nukuri.
GB / T 41-2016 "Ubwoko bwa 1 Hexagon Nuts Grade C" yerekana imbuto zifite amanota C neza.
GB / T.
Muri GB / T 6170-2015 “Ubwoko bwa 1 Imbuto ya Hexagonal”, GB / T 6175-2016 “Ubwoko bwa 2 Imbuto ya Hexagonal” na GB / T 6172.1-2016 “Imbuto nini ya Hexagonal”, Icyiciro A gikoreshwa mu mbuto zifite D≤16mm;Icyiciro B gikoreshwa mubuto hamwe na D> 16mm.
Ukurikije ibipimo ngenderwaho byigihugu GB / T 3103.1-2002 “Byihuta byihanganira Bolts, Imigozi, Inyigo nimbuto”, icyiciro cyo kwihanganira urudodo rwimbere rwa A-urwego na B urwego rwuzuye ni “6H”;Urwego rwo kwihanganira urwego rwimbere ni "7H";amanota yo kwihanganira izindi ntera yimbuto ziratandukanye ukurikije ukuri kw'amanota A, B na C.
3. Ibyiciro bitandukanye byimiterere yubukanishi
Dukurikije ibivugwa mu rwego rw’igihugu GB / T 3098.2-2015 “Ibyiza bya mashini byimbuto zihuta”, ibyuma bikozwe mu byuma bya karubone n’ibyuma bivangavanze bifite ubwoko 7 bw’amanota yo gukora mu rwego rw’ibidukikije biri hagati ya 10 ° C kugeza 35 ° C.Ni 04, 05, 5, 6, 8, 10, 12.
Dukurikije ibivugwa mu rwego rw’igihugu GB / T 3098.15-2014 “Ibyiza bya Mechanical of Fasteners Stainless Steel Nuts”, iyo ibipimo by’ibidukikije ari 10 ° C kugeza kuri 35 ° C, amanota yimikorere yimbuto zikoze mubyuma bitagaragara neza kuburyo bukurikira :
Imbuto zikozwe mu byuma bya austenitike (harimo A1, A2, A3, A4, A5 matsinda) bifite imiterere ya mashini ya 50, 70, 80 na 025, 035, 040. ibice, igice cya mbere kiranga itsinda ryibyuma, naho igice cya kabiri kiranga urwego rwimikorere, rutandukanijwe nuduce, nka A2-70, kimwe hepfo)
Imbuto zikoze muri martensitike idafite ibyuma byitsinda C1 zifite amanota yumutungo wa 50, 70, 110 na 025, 035, 055;
Imbuto zikoze muri martensitike idafite ibyuma ya groupe C3 ifite imashini ya 80 na 040;
Ibinyomoro bikozwe mu byuma bya martensitike bidafite itsinda rya C4 bifite amanota yumutungo wa 50, 70 na 025, 035.
Ibinyomoro bikozwe mu itsinda rya F1 ferritic idafite ibyuma bifite amanota yumutungo wa 45, 60 na 020, 030.
Ukurikije ibivugwa mu rwego rw’igihugu GB / T 3098.10-1993 “Ibyiza bya mashini byizirika - Bolt, Imigozi, Inyigo nimbuto zikozwe mu byuma bidafite fer”:
Imbuto zikozwe mu muringa n'umuringa zifite amanota yo gukora: CU1, CU2, CU3, CU4, CU5, CU6, CU7;
Imbuto zikoze muri aluminium na aluminiyumu zifite amanota yo gukora: AL1, AL2, AL3, AL4, AL5, AL6.
Igipimo ngenderwaho cyigihugu GB / T 41-2016 "Ubwoko bwa 1 Hexagon Nut Grade C" irakoreshwa mubyiciro bya C hexagon nuts hamwe nibisobanuro M5 ~ M64 nicyiciro cya 5.
Igipimo cyigihugu GB / T 6170-2015 "Ubwoko bwa 1 Hexagon Nut" burakoreshwa mubisobanuro byihariye M1.6 ~ M64, amanota yimikorere ni 6, 8, 10, A2-70, A4-70, A2-50, A4-50 , CU2, CU3 na AL4 urwego A na B hex nuts.
Igipimo ngenderwaho cyigihugu GB / T 6175-2016 "Ubwoko bwa 2 Hexagon Nuts" burakoreshwa mubyiciro A na B B ya Hexagon umutwe wumutwe ufite ibisobanuro byihariye M5 ~ M36 hamwe nicyiciro cya 10 na 12.
Igipimo cyigihugu GB / T 6172.1-2016 "Hexagon Thin Nut" irakoreshwa mubisobanuro byinsanganyamatsiko M1.6 ~ M64, amanota yimikorere ni 04, 05, A2-025, A2-035, A2-50, A4-035, CU2, CU3 na AL4 urwego A na B impande esheshatu zoroshye.
Urutonde rwa diametre nominal ihuye nubwoko bwimbuto nicyiciro cyimikorere irerekanwa mumeza hepfo.
Imbuto zisanzwe (ubwoko bwa 1) hamwe nutubuto twinshi (ubwoko bwa 2) bukozwe mubyuma bya karubone hamwe nicyuma kivanze bigomba gukoreshwa hamwe nudushumi two hanze twiziritse kumeza ikurikira, kandi ibinyomoro bifite ingufu nyinshi murwego rwo hejuru birashobora gusimbuza ibinyomoro amanota yo hasi.
Imbuto zisanzwe (ubwoko bwa 1) nizo zikoreshwa cyane.
Imbuto ndende (ubwoko bwa 2) zikoreshwa muri rusange zisaba gusenywa kenshi.
Utubuto duto (Ubwoko 0) dufite umutwaro muto wo gutwara ubushobozi burenze ibisanzwe cyangwa birebire, bityo ntibigomba gukorerwa porogaramu zo kurwanya ingendo.
Utubuto duto (ubwoko bwa 0) muri rusange dukoreshwa muburyo bubiri-bubi burwanya kurekura.
