Njira yosinthira pakati pa zingwe ndi ulusi wogwirizana

Ulusi ndi mawonekedwe ozungulira omwe amagwiritsidwa ntchito polumikiza mabawuti ndi mtedza. M'mayiko ndi zigawo zosiyanasiyana, mitundu yosiyanasiyana ya ulusi imagwiritsidwa ntchito. Imperial ndi metric ndiye miyezo iwiri yodziwika bwino.
Mu British standard, Zodziwika bwino za UNC ndi UNF. UNC ndiye chidule cha Unified National Coarse, zomwe zikutanthauza ulusi wogwirizana wa dziko; UNF ndiye chidule cha Unified National Fine, zomwe zikutanthauza ulusi wogwirizana wa dziko. Mwachitsanzo, Kusapanda 1/4-20 kutanthauza ulusi wolumikizana wadziko lonse wokhala ndi phula la 20 TPI (ulusi pa inchi) ndi diameter ya 1/4 nsonga.

Ulusi wolumikizana wa inchi amagwiritsidwa ntchito kwambiri m'maiko a inchi. Ulusi wamtunduwu umagawidwa m'magulu atatu: UNC, ulusi wabwino kwambiri UNF, ulusi wowonjezera wa UNFF, kuphatikiza mndandanda wokhazikika wa UN.

Njira yolembera: Ulusi wapakati - chiwerengero cha ulusi pa inchi; Mndandanda wa code-kulondola mlingo

Chitsanzo: Coarse dzino mndandanda 3/8-16 UNC-2A

Fine dzino mndandanda 3/8-24 Osakhala 2

Zina zabwino kwambiri mndandanda wa mano 3/8-32 UNFF-2A

3/8—20 UN—2A

Nambala yoyamba 3/8 imayimira kukula kwakunja kwa ulusi mu mainchesi. Kuti mutembenuzire ku metric unit mm, chulukitsani ndi 25.4, kuti, 3/8×25.4= 9.525 mm; manambala achiwiri ndi achitatu 16, 24, 32, ndi 20 ndi Chiwerengero cha mano pa inchi (chiwerengero cha mano pa utali wa 25.4mm); zolemba pambuyo pa nambala yachitatu, Kusapanda, Osa, UNFF, NDI, ndi ma code code, ndi manambala awiri omaliza, 2A, ndi mulingo wolondola.

Zimanenedwa mu ulusi wogwirizana kuti kukula kwadzina kumatha kukhala ndi mapilo osiyanasiyana. Mwachitsanzo, 1/2 ali 13 mano, 16 mano, 20 mano, ndi 32 mano. Mulingo umanena zimenezo 13 mano ndi olimba mano ndi 20 mano ndi mano abwino. 28 mano ndi mano abwino kwambiri; 16 mano ndi 32 mano onse amatchedwa phula lokhazikika, amene si wosiyana ndi mano osalimba ndi mano abwino.
