Wigishe kumenya ibikoresho byo murwego rwa bolts ukireba

Bolt ni ibice bisanzwe byubukanishi, bikunze gukoreshwa ahantu henshi, ni kumutwe no gusunika ibice bibiri byitsinda ryiziritse, bigomba gukoreshwa bifatanije nimbuto, cyane cyane bikoreshwa muguhuza ibice bibiri hamwe nu mwobo. Birashoboka ko udasobanukiwe nibintu byamanota ya bolt, iyi ngingo izakumenyesha kubintu bya bolt, ubumenyi bujyanye n amanota, kugirango ureke abantu benshi biga kumenya utuntu duto twa bolt.

Amanota n'ibikoresho bya bolts bivuga iki?

Urwego rwa Bolt rwerekeza kuri bolt ni 4.8 kuzamura, 8.8 amanota, 10.9 amanota nizindi ntera.

Ibikoresho bivuga kuri bolt ikozwe mubintu, nka Q235, 35K, 40Cr, 45 # ibyuma, 35CrMo ibyuma, 304 ibyuma bitagira umwanda na 316 ibyuma bidafite ingese nibindi.

Urwego rwa Bolt nibikoresho ni isano runaka, ibyuma byoroheje bishobora kubyara gusa imbaraga zo mu rwego rwo hasi, ibyuma bya karubone yo hagati birashobora kubyara ingufu zo mu rwego rwo hejuru, ibyuma bya karubone ndende, ibyuma bivanze bishobora kubyara imbaraga zo mu rwego rwo hejuru. Urwego rwa bolt rugaragaza imiterere ihwanye nubumashini, ariko kandi kugirango umenye ibikoresho.

Dore urutonde rwamanota asanzwe ya bolts arashobora kuba ibikoresho. Urwego 4.8 rushobora kuba Q235, Q195 nibindi bikoresho byoroheje. 5.8 urwego Q235 hejuru yibikoresho byose birashobora kuba, ntukeneye kuvura ubushyuhe. 8.8 urwego rwumurambararo wa 16MM cyangwa munsi yayo, 35 # kuvura ubushyuhe, 16mm cyangwa irenga, 45 # hamwe na karuboni nkeya ya karuboni. 10.9 urwego rwo hagati ya karubone ivanze nicyuma gishyushya Ubushyuhe 35Crmo 40Cr nibindi.

Ese imbaraga-zohejuru zishobora gutandukana nibisanzwe hamwe nibikoresho byabo?

Mubisanzwe bigabanijwe ukurikije urwego rwimbaraga.

Urwego rwimikorere ya Bolt 3.6, 4.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9, 12.9 nibindi kumanota arenga 10, muribo 8.8 no hejuru ya bolts ikozwe mubyuma bya karuboni nkeya cyangwa ibyuma bya karuboni yo hagati hamwe nicyuma gikoreshwa nubushyuhe (kuzimya, kurakara), bizwi cyane nkibisanzwe byitwa bolts. Urwego rwa Bolt rwerekana urwego rufite ibice bibiri bigize sisitemu ya digitale, uko bikurikirana, ko imbaraga zomwanya zingirakamaro zingirakamaro ya bolt yibikoresho nagaciro kagereranijwe.

Kurugero, imikorere urwego 8.8 amanota ya bolts, ibisobanuro ni:

1, bolt material nominal tensile imbaraga za 800MPa urwego;

2, ibikoresho bya bolt bitanga imbaraga zingana na 0.8;

3, imbaraga zumusaruro wizina ryibikoresho bya bolt bigera kuri 800 × 0.8 = 640MPa urwego rwakunze gukoreshwa cyane-imbaraga zo murwego rwa 8.8 na 10.9, zikoreshwa cyane mubisanzwe bisanzwe kurwego rwa 4.8.
