Igipimo gisanzwe cyerekana imiyoboro

Ibipimo bikoreshwa cyane ni ibi bikurikira:
Igipimo cy’igihugu cy’Ubushinwa (Igipimo cy’igihugu)
Igipimo cy’igihugu cya ANSI-Amerika (Igipimo cy’Abanyamerika)
DIN-Ubudage Bwigihugu (Ikidage)
Sosiyete ASME-Amerika y'Abashinzwe Imashini Zisanzwe
JIS-Yapani Igipimo cyigihugu (Ikiyapani gisanzwe)
BSW-Igipimo cy’igihugu cy’Ubwongereza

Usibye ibipimo bimwe byibanze, nkubunini bwumutwe hamwe numutwe uhanganye, igice gitandukanye cyibipimo byavuzwe kuri screw ni urudodo. Urudodo rwa GB, DIN, JIS, nibindi byose biri muri MM (milimetero) , twese hamwe twavuga nkinsanganyamatsiko.Imitwe nka ANSI, ASME, iri muri santimetero kandi yitwa insanganyamatsiko isanzwe y'Abanyamerika.Usibye urudodo rwa metero hamwe nududodo twabanyamerika, hariho na BSW-Ubwongereza, kandi insanganyamatsiko nazo ziri muri santimetero, zizwi ku izina rya Whitworth.

Urudodo rwibipimo ruri muri MM (mm), kandi impande ya cusp ni dogere 60.Byombi insinga zabanyamerika na Imperial zapimwe muri santimetero.Inguni ya cusp y'urudodo rw'Abanyamerika nayo ni dogere 60, mugihe inguni ya cusp y'urudodo rw'Ubwongereza ari dogere 55.Bitewe nibice bitandukanye byo gupima, uburyo bwo guhagararira insanganyamatsiko zitandukanye nabwo buratandukanye.Kurugero, M16-2X60 yerekana insanganyamatsiko.Bisobanura neza ko diameter nominal ya screw ari 16MM, ikibuga ni 2MM, n'uburebure ni 60MM.Urundi rugero: 1 / 4-20X3 / 4 bisobanura umurongo wubwongereza.ibisobanuro byayo byihariye ni diameter nominal ya screw ni 1/4 santimetero (santimetero imwe = 25.4MM), hari amenyo 20 kuri santimetero imwe, n'uburebure ni 3/4.Byongeye kandi, niba ushaka kwerekana imigozi yakozwe nabanyamerika, UNC na UNF mubisanzwe byongerwaho nyuma yimigozi yakozwe nabongereza kugirango batandukane nududodo twinshi twakozwe nabanyamerika nuudodo twiza twakozwe na Amerika.

Yihe uruganda nisosiyete izobereye mu gukora amine ya amchine yakozwe muri Amerika ANSI, imashini ya BS, imashini ya bolt, indlcuidng 2BA, 3BA, 4BA;Imashini yakozwe nubudage imashini DIN (DIN84 / DIN963 / DIN7985 / DIN966 / DIN964 / DIN967);Urutonde rwa GB nubundi bwoko bwibicuruzwa bisanzwe kandi bitari bisanzwe nkibikoresho byimashini nubwoko bwose bwimashini zumuringa.
