Amashurwe yindabyo hamwe ninkingi yo kwikubita agati

Usibye gutandukana mubipimo byibanze nkumutwe kugeza kumutwe nubunini bwumutwe, itandukaniro ryingenzi mubipimo ni itandukaniro mubice. Urudodo rwa GB, DIN, JIS, nibindi byose bipimwa muri milimetero (MM) kandi hamwe hamwe byitwa insanganyamatsiko. Insanganyamatsiko nka ANSI, ASME, nibindi, bipimwa muri santimetero, byitwa insanganyamatsiko isanzwe y'Abanyamerika. Usibye insanganyamatsiko za metero hamwe nududodo twabanyamerika, hari nuburinganire bwa BSW bwabongereza, insanganyamatsiko nayo ipimwa muri santimetero, bakunze kwita Wyeth.

Urudodo rwibipimo rwapimwe muri milimetero (MM) kandi rufite iryinyo ryinyo ya dogere 60. Imitwe yombi y'Abanyamerika n'Ubwongereza ipimwa muri santimetero. Inguni y'amenyo y'urudodo rw'Abanyamerika nayo ni dogere 60, mugihe iryinyo ryinyo yumutwe wu Bwongereza ni dogere 55. Bitewe nibice bitandukanye byo gupima, uburyo bwo guhagararira insanganyamatsiko zitandukanye nabwo ntabwo ari bumwe. Kurugero, M16-2X60 yerekana insanganyamatsiko. Igisobanuro cye cyihariye nuko diameter nominal ya screw ari 16MM, ikibuga ni 2MM, n'uburebure ni 60MM. Kurugero, 1 / 4-20X3 / 4 byerekana urudodo rwabongereza, kandi ubusobanuro bwe bwihariye nuko diameter nominal ya screw ari 1/4 santimetero (santimetero imwe = 25.4MM), ifite amenyo 20 kuri santimetero imwe n'uburebure bwa 3/4. Byongeye kandi, iyo uvuze imigozi y'Abanyamerika, UNC na UNF mubisanzwe byongerwaho nyuma yo guhagararira imigozi yabongereza kugirango itandukanye amenyo mabi yabanyamerika n amenyo meza yabanyamerika.

Mubucuruzi bwacu bwo kugurisha burimunsi, ibipimo dukunze guhura nabyo ni GB (National Standard) na DIN (Ikidage gisanzwe).
Kubijyanye nibicuruzwa bidafite impumuro nziza, amahame akurikira arahura cyane: GB30; GB5783; GB5782; GB62; GB6170; GB818; GB819; GB845; GB846; GB70; DIN912; DIN933; DIN931, nibindi Kugeza ubu, GB30 (urwego rwigihugu rushaje) rwasimbuwe na GB5783 (urwego rushya rwigihugu) mugitabo gisanzwe. GB52 (urwego rwigihugu rushaje) rwasimbuwe na GB6170 (urwego rushya rwigihugu) mugitabo gisanzwe.

Mu 1986, igihugu cyacu cyashyizeho urwego rushya rwibigize bisanzwe, bizwi nkurwego rushya mubucuruzi. Izikoreshwa cyane ni GB5780, GB5781, GB5782, GB5783, na GB5784. GB5780 ni umutwe wa mpande esheshatu zuzuye igice cyinyo yinyo yinyo ifite urwego rwukuri rwa C, rushobora gusimburwa na GB5782 (GB5782 numutwe wa mpande esheshatu zuzuye inkoni yuzuye amenyo yuzuye amenyo afite urwego rwukuri rwa A na B). GB5781 ni umutwe wa mpande esheshatu zuzuye amenyo afite urwego rwukuri rwa C. GB5783 irashobora gukoreshwa nkuwasimbuye (GB5783 numutwe wa mpandeshatu wuzuye amenyo yuzuye amenyo afite urugero rwa A na B). GB5784 ni umugozi wa mpandeshatu ufite inkoni yoroheje n'amenyo y igice.

Itandukaniro riri hagati yikirango gishya na label ishaje nuko ibicuruzwa bya M8, M10, M12, M14, na M22 bifite itandukaniro mubugari bwimpande. Usibye ibicuruzwa bishya bya M22, impande zumutwe wibicuruzwa bishya bya label M8, M10, M12, na M14 ni 1MM ntoya ugereranije nibirango bishaje. Ni 13mm, 16mm, 18mm, na 21mm. Ariko, kubicuruzwa bishya bya M22, uruhande rutandukanye rwa label nshya mubyukuri ni 2MM iruta ikirango gishaje, bityo rero hagomba kwitabwaho byumwihariko. Kubwubunini bwumutwe, hari itandukaniro rito hagati yuburyo bushya nibishaje, bushobora gukoreshwa muburyo butandukanye aho ibisabwa bidakabije.

Itandukaniro riri hagati yuburyo bushya nubudage busanzwe buri mubicuruzwa byihariye bya M10, M12, M14, na M22, bitandukanye mubugari bwimpande. Umutwe wo kuruhande rushya rwa M10, M12, M14 ugomba kuba muto 1MM ugereranije nubudage. Igicuruzwa gishya cya M22 gifite ubugari bwumutwe ufite ubugari bwa 2MM kurenza ubugari bwagaragaye, nibindi bicuruzwa byose birashobora gukoreshwa muburyo bumwe.

Ku mbuto esheshatu, ibisanzwe bikoreshwa harimo GB52, GB6170, GB6172, na DIN934. Itandukaniro nyamukuru hagati yabo nuko GB6170 ifite umubyimba urenze GB52, GB6172, na DIN934, bakunze kwita imbuto zimbuto. Mubyongeyeho, hari itandukaniro kumpera. Muri serivise ya M8, impande za DIN934, GB6170, na GB6172 ni 13mm, ni 1MM ntoya kurenza 14mm ya GB52. Kuri M10 nuts, impande za DIN934 na GB52 ni 17mm, ni 1MM nini kuruta impande za GB6170 na GB6172. Kubuto bwa M12, impande za DIN934 na GB52 ni 19mm, ni 1MM nini kuruta 18mm ya GB6170 na GB6172. Kuri M14 nuts, impande zinyuranye za DIN934 na GB52 ni 22mm, ni 1MM nini kuruta impande zombi za GB6170 na GB6172, ni 21mm. Byongeye kandi, ibinyomoro M22 bifite 32MM ihabanye na DIN934 na GB52, ikaba ari 2MM ntoya kuruta 34MM ihabanye na GB6170 na GB6172. GB6170 na GB6172 bifite ubugari bumwe gusa usibye ubunini butandukanye. Ibindi bisobanuro byose birashobora gukoreshwa muburyo butandukanye utitaye kubyimbye.
