Kodi kalasi yoyenera kwa ulusi ndi chiyani?
Makalasi oyenererana ndi ulusi amatanthauzira mitundu yovomerezeka ya miyeso ya ulusi wamkati (nati) ndi wakunja (bawuti). Kulekerera uku ndikofunikira chifukwa kumatsimikizira momwe mbali ziwiri zolimba kapena momasuka zidzalumikizana. Kusankha koyenera kwa kalasi yoyenera kumatha kuletsa kumangirira, kuchepetsa kuvala, komanso kukulitsa luso la msonkhano.
Maphunziro a Imperial Thread Fit
Kwa Unified Inchi Screw Threads (UN), pali makalasi atatu oyambira oyenera:
- 1A/1B: Wodziwika ndi zovomerezeka zazikulu, zotayirirazi ndizoyenera kugwiritsa ntchito pomwe kusonkhana kumakhala kofunika kwambiri kuposa kuthina.
- 2A/2B:Kalasi yodziwika bwino kwambiri, yopereka miyeso pakati pa kumasuka kwa msonkhano ndi mphamvu zokwanira zogwirira. Amagwiritsidwa ntchito kwambiri m'mafakitale ambiri.
- 3A/3B: Kupereka kolimba kwambiri, kumatsimikizira kulimba kwambiri komanso kusewera kochepa. Zoyenera kumalo opsinjika kwambiri kapena kugwiritsa ntchito chitetezo chofunikira kwambiri.
Maphunziro a Metric Thread Fit
Metric screw ulusi amatsata miyezo ya ISO yokhala ndi makalasi oyenera omwe akuphatikiza:
- 4 ,6h ndiza ulusi wakunja
- 5H, 6H, 7Hza ulusi wamkati
Maina a 'h' ndi 'H' amatanthauza zopatuka ziro, pomwe 'g' ndi 'G' akuwonetsa zopatuka zabwino kapena zoyipa. Zomwe zimalimbikitsidwa nthawi zambiri ngati 6H / 6g zimapereka magwiridwe antchito odalirika pazomangira zanthawi zonse.
Kusankha Kalasi Yoyenera Yoyenera
Kusankha kalasi yoyenera ya ulusi kumatengera zinthu zingapo:
- Zofunikira pa Ntchito:Ganizirani ngati gululo likufunika kuphwanyidwa pafupipafupi, limagwira ntchito movutikira, kapena likuyenera kukwaniritsa miyezo yolimba yachitetezo.
- Zinthu Zakuthupi: Zida zosiyanasiyana zimakhala ndi ma coefficients osiyanasiyana akukula kwamafuta ndi zotanuka, zomwe zimatha kukhudza kusankha koyenera.
- Maluso Opanga: Kutha kukwaniritsa kulolerana kolondola kumatha kuchepetsa zosankha zomwe zilipo.
Makalasi oyenererana ndi ulusi ndizofunikira kwambiri pakupanga ndi kupanga zida za ulusi. Pomvetsetsa ndikugwiritsa ntchito miyezo imeneyi moyenera, mainjiniya amatha kukulitsa magwiridwe antchito amisonkhano yamakina, kuwonetsetsa kudalirika komanso moyo wautali. Kaya mukugwira ntchito ndi makina achifumu kapena ma metric, kusankha kalasi yoyenera ndikofunikira pamayankho opambana aukadaulo.
Zikomo powerenga, ngati mukufuna kuwona zambiri zomwe timapereka mutha kutsatira maulalo pansipa!
