Umzi-mveliso wenze iiNdawo ezahlukeneyo zelori yeBolt kwiNqanaba yeeBolts zeTorsional Shear

Amanqaku ebholidi kunye namabakala okusebenza
(1) Ilogo.Iibholiti zeHexagon kunye nezikrufu (umsonto ubukhulu ≥5mm).I-convex okanye uphawu lwe-concave phezu kwentloko okanye uphawu lwe-concave ecaleni kwentloko luyafuneka.Kubandakanya ibakala lokusebenza, umgangatho wefektri.Intsimbi yekhabhoni: Ikhowudi yokumakisha yebakala lamandla inamanani amabini ahlulwe ngo “·”.Inxalenye yamanani ephambi kuka “·” kwikhowudi yokumakisha ibonisa amandla okuzinza okuqhelekileyo.Umzekelo, “4″ kwibanga lesi-4.8 ithetha i-1/100 yamandla e-tensile ye-400N/MM2.Intsingiselo yegama elithi “·” kunye nenxalenye yedijithali emva kwechaphaza kwikhowudi yokumakisha ibonisa umlinganiselo wesivuno, oko kukuthi, umlinganiselo wenqaku lesivuno okanye isivuno samandla esisigama kumandla okuzinza okuqhelekileyo.Ngokomzekelo, inqaku lesivuno sebanga le-4.8 lemveliso yi-320 N / mm2.Uphawu lwamandla emveliso yensimbi engenasici luqulunqwe ngamacandelo amabini ahlulwe ngu "-".Isimboli phambi kuka-“-” ibonisa imathiriyeli.Ngokomzekelo, i-A2 kunye ne-A4 ibonisa amandla emva kwe-, umzekelo, i-A2-70

(2) IBanga.Intsimbi yeCarbon: Ibakala lentsebenzo lomatshini leMetric bolt linokohlulwa libe: 3.6, 4.6, 4.8, 5.6, 5.8, 6.8, 8.8, 9.8, 10.9, 12.9 iyonke yamabakala okusebenza ali-10.Insimbi engenasici ihlulwe ibe yi-60,70,80 (austenite);50,70,80,110(martensite);45,60 (ferrite) iklasi iii.
