Urutonde rwimikorere

Urwego rwimikorere ya Bolt, arirwo rwego rwimikorere ya bolt yo guhuza ibyuma, igabanijwemo amanota arenga 10, nka 3.6, 4.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9, 12.9, nibindi. ibice bibiri, byerekana izina nominal tensile imbaraga zingirakamaro hamwe nigipimo cyingufu zingana yibikoresho bya bolt.

Ubusobanuro bwibikorwa bya bolt ni urwego mpuzamahanga rusanzwe, bolt yo murwego rumwe rwimikorere, tutitaye kubitandukanya ryibikoresho byayo ninkomoko, imikorere yayo ni imwe, igishushanyo gishobora guhitamo gusa amanota yimikorere.

Imbaraga zo mu cyiciro cya 8.8 na 10.9 bivuga urwego rwo guhangayikishwa no gukata kwa bolt ni 8.8 GPa na 10.9 GPa 8.8 nominal tensile imbaraga za 800 n / 640 n yari nominal umusaruro wimbaraga bolts / muri rusange byagaragajwe mumbaraga za "XY", X * 100 = imbaraga za bolt tensile, X * 100 * (Y / 10) = umusaruro wimbaraga za bolt (nkuko biteganijwe mubirango: umusaruro / imbaraga zingana = Y / 10, aribyo 0. Y yerekanye) nkubunini bwa 4.8, imbaraga zingana za bolt ni: 400 mpa.Imbaraga z'umusaruro: 400 * 8/10 = 320MPa. Ubundi: ibyuma bitagira umuyonga mubisanzwe byanditseho A4-70, isura ya A2-70, bivuze ubundi gusobanura ibipimo: gupima uburebure kwisi uyumunsi hariho ubwoko bubiri bwingenzi, bumwe kuri sisitemu ya metero, igipimo cyo gupima ni metero (m), santimetero (cm), mm (mm), nibindi, muburayi, Ubushinwa n'Ubuyapani hamwe nubundi majyepfo yuburasirazuba bwa Aziya gukoresha ni byinshi, ikindi nicyongereza, igipimo cyo gupima ahanini kuri santimetero (santimetero), gikoreshwa cyane muri Amerika, Ubwongereza no mubindi bihugu byu Burayi na Amerika.1. Ibipimo bya sisitemu ya metero: 1m = 100 cm = 1000 mm2, gupima sisitemu yicyongereza: (8) 1 inch = 8 ints 1 inch = 25.4 mm

Bolt ikoreshwa muguhuza ibyuma byubatswe bifite amanota arenga 10, harimo 3.6, 4.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9 na 12.9.Icyiciro cyerekana imikorere ya Bolt igizwe nibice bibiri, byerekana izina ryimbaraga zingirakamaro kandi igipimo cyingufu zingirakamaro yibikoresho bya bolt.Urugero: bolts ifite amanota 4.6, bivuze:
1. Imbaraga zumwanya wizina wibikoresho bya bolt bigera kuri 400MPa;
2. Ikigereranyo cyingufu zigoramye yibikoresho bya bolt ni 0,6;
3. Imbaraga zumusaruro wizina ryibikoresho bya bolt bigera kuri 400 × 0,6 = 240MPa icyiciro
Urwego rwimikorere 10.9 imbaraga zikomeye bolt, ibikoresho byayo nyuma yo kuvura ubushyuhe, birashobora kugeraho:
1. Imbaraga zumwanya wizina wibikoresho bya bolt bigera kuri 1000MPa;
2. Ikigereranyo cyingufu zingana zigikoresho cya bolt ni 0.9;
3. Imbaraga zumusaruro wizina ryibikoresho bya bolt bigera ku 1000 × 0.9 = 900MPa icyiciro
