Indlela yokuguqula phakathi kwe-metric kunye ne-intshi ye-intshi

Umsonto sisakhiwo esijikelezayo esisetyenziselwa ukudibanisa iibholithi kunye namandongomane. Kumazwe kunye nemimandla eyahlukeneyo, kusetyenziswa imigangatho eyahlukeneyo yomsonto. I-imperial kunye ne-metric yimigangatho emibini eqhelekileyo.
Kumgangatho waseBritane, iinkcukacha zemisonto eqhelekileyo yi-UNC kunye ne-UNF. I-UNC sisishunqulelo se-Unified National Coarse, elibhekiselele kumsonto orhabaxa omanyeneyo wesizwe; I-UNF sisishunqulelo seFini yeSizwe eManyeneyo, elibhekiselele kumsonto welizwe omanyeneyo. Umzekelo, UNC 1/4-20 lithetha umsonto orhabaxa odibeneyo wesizwe onepitch ye 20 TPI (imisonto nge-intshi nganye) kunye nobubanzi be 1/4 intshi.

Inkqubo ye-intshi imisonto emanyeneyo isetyenziswa ngokubanzi kumazwe enkqubo yee-intshi. Olu hlobo lwentambo lwahlulwe lwaba luchungechunge oluthathu: uthotho intambo erhabaxa UNC, uthotho intambo entle UNF, uthotho lomsonto owongezelelweyo UNFF, kunye nothotho lwepitch esisigxina UN.

Indlela yokumakisha: Idayamitha yomsonto-inani lemisonto nge-intshi nganye; Uluhlu lwekhowudi-inqanaba lokuchaneka

Umzekelo: Uthotho lwezinyo elirhabaxa 3/8-16 UNC-2A

Uthotho lwamazinyo amahle 3/8-24 I-UNF-2A

Uthotho lwamazinyo olongezelelweyo 3/8-32 UNFF-2A

Uthotho lwepitch ezinzileyo 3/8—20 UN—2A

Idijithi yokuqala 3/8 imele i-diameter yangaphandle yomsonto kwii-intshi. Ukuguqulela kwiyunithi yemetric mm, phindaphinda nge 25.4, yiyo i, 3/8×25.4=9.525mm; idijithi yesibini neyesithathu 16, 24, 32, kwaye 20 zi Inani lamazinyo nge-intshi nganye (inani lamazinyo kubude obuyi-25.4mm); iikhowudi zokubhaliweyo emva kwedijithi yesithathu, UNC, UNF, UNFF, KUNYE, ziikhowudi zothotho, kunye namanani amabini okugqibela, 2A, zinqanaba lokuchaneka.

Kukhankanyiwe kumgangatho odityanisiweyo womsonto ukuba ubungakanani obuqhelekileyo bunokuba neepatshi ezahlukeneyo. Umzekelo, 1/2 uye 13 amazinyo, 16 amazinyo, 20 amazinyo, kwaye 32 amazinyo. Umgangatho uchaza oko 13 amazinyo ngamazinyo arhabaxa kwaye 20 amazinyo ngamazinyo amahle. 28 amazinyo ngamazinyo acolekileyo kakhulu; 16 amazinyo kunye 32 amazinyo omabini abizwa ngokuba yipitch engaguqukiyo, ayahlukanga kumazinyo arhabaxa namazinyo amahle.
