Uyini umehluko phakathi kwentambo ye-metric

Induku ye-metric intambo rodna-I-British American Threaded Rodziyizindinganiso ezimbili ezihlukile zokukhiqiza intambo. Umehluko phakathi kwabo uboniswa ikakhulukazi ngendlela yokumelwa ngosayizi, inani lemicu, i-angle ye-bevel kanye nobubanzi bokusebenzisa. Ekukhiqizweni kwemishini, kuyadingeka ukuthi ukhethe izinga lentambo efanele ngokwesimo esithile ..

1. Uyini umehluko omkhulu phakathi kwe-metric Stud Bolt neBritish and American BOLT BOLT?

I-Metric Stud Boltwathandwa eFrance, futhi izici zawo ukuthi zisebenzisa amamilimitha njengamayunithi, zinezintambo ezimbalwa, futhi zine-bevel angle yama-60 degrees. Le khasiIBritish and American Stud BoltUkuqhamuka e-United Kingdom nase-United States, kanye nezimpawu zalo ukuthi isebenzisa ama-intshi njengamayunithi, inemicu eminingi, futhi ine-bevel angle yama-degree angama-55.

2. Uyini umehluko phakathi kwe-metric threaded rod din975 kanye neBritish and American Threaded Rine Din975 Threw Thread Dishes?

Ngosayizi, usayizi we-metric Threads RED975 uvezwa ngokuya ngobubanzi (mm) kanye ne-pitch (mm), ngenkathi imicu yaseBrithani neyaseMelika) ivezwa ngohlelo lwe-usayizi (intshi), uhlelo lwe-pitch, kanye nentambo (inani lemicu).

Isibonelo, intambo ye-M8 x 1.25, lapho i- "M8" imele ububanzi be-8 mm, futhi "1.25" imelela ibanga elingu-1.25 mm phakathi kwentambo ngayinye. Ezintanjeni zaseBrithani naseMelika, i-1/4 -20 imele usayizi wentambo ka-1/4 intshi, iphimbo lezintambo ezingama-20 nge-intshi ngayinye, futhi i-UNC imele izinga elijwayelekile lokusanhlamvu kwentambo.

Njengoba umenzi we-metric enomugqa we-threaded enezintambo ezimbalwa futhi ama-bevels amancane, akulula ukuluma ngejubane elikhulu, ngakho-ke izingxenye eziningi zemishini zisebenzisa imicu yemitic. Imicu yaseBrithani neyaseMelika ivame ukusetshenziswa ngezikhathi ezithile ezikhethekile, njengemicu yepayipi yaseMelika.

4. Ukucaciswa Ukuguqulwa

Njengoba imicu ye-metric kanye nemicu yaseBrithani neyaseMelika iyindinganiso ezimbili zokukhiqiza, ukuguqulwa kuyadingeka. Izindlela ezijwayelekile zokuguqula zifaka ukusebenzisa amathuluzi wokuguqula noma ukubhekisela kumatafula wokuguqula.
