Imashini ya JinQiang: Imbaraga zingirakamaro hamwe nisesengura ryimbaraga za bolts

1. Urwego rwimbaraga

Urwego rwimbaraga zamakamyohub boltsmubisanzwe bigenwa ukurikije uburyo bwabo bwo gutunganya ubushyuhe. Imbaraga zisanzwe zirimo 4.8, 8.8, 10.9, na 12.9. Aya manota agereranya ibintu, ubukana hamwe numunaniro wa bolts mubihe bitandukanye.

Icyiciro 4.8: Iyi ni imbaraga nkeya, ikwiranye nigihe kimwe hamwe nimbaraga nke zisabwa.
Icyiciro 8.8: Iki nicyiciro gisanzwe cya bolt imbaraga, gikwiranye nuburemere rusange buremereye hamwe nibikorwa byihuta.
Icyiciro 10.9 na 12.9: Ibi byuma byombi bifite imbaraga nyinshi mubisanzwe bikoreshwa mugihe hagomba gukenerwa imbaraga nigihe kirekire, nkamakamyo manini, ibinyabiziga byubwubatsi, nibindi.

2. Imbaraga zikomeye

Imbaraga zingutu bivuga guhangayikishwa cyane nuko bolt ishobora kunanira kumeneka iyo ikozwe ningufu zikomeye. Imbaraga zingana za kamyo yimodoka hub bolts ifitanye isano rya hafi nimbaraga zayo.

Imbaraga zingirakamaro zicyiciro cya 8.8 zisanzwe ni 800MPa naho imbaraga zumusaruro ni 640MPa (igipimo cyumusaruro 0.8). Ibi bivuze ko mugihe gisanzwe cyo gukoresha, bolt irashobora kwihanganira imihangayiko igera kuri 800MPa itavunitse.
Kuri bolts yimbaraga zo hejuru amanota, nkicyiciro 10.9 na 12.9, imbaraga zingana zizaba nyinshi. Ariko, twakagombye kumenya ko imbaraga zingutu zitari hejuru kurwego rwiza, ariko urwego rukwiye rwa bolt rukeneye guhitamo ukurikije ibidukikije byakoreshejwe nibisabwa.
