Ihuza-imbaraga-nini ya bolt iranyuze muburyo bukomeye bwo kwiyitirira bolt inkoni imbere yisahani ya plaque ihuza ibice, bihagije kugirango bitange ubushyamirane bwinshi, kugirango uzamure ubunyangamugayo no gukomera kwihuza, mugihe icyogosho, ukurikije ibisabwa kuri igishushanyo na stress biratandukanye, birashobora kugabanywa muburyo bwo guterana imbaraga zikomeye za bolt ihuza hamwe nimbaraga nyinshi zihuza ubwoko bubiri bwumuvuduko, ni itandukaniro ryibanze hagati yimipaka yombi imipaka iratandukanye, nubwo ari ubwoko bumwe bwa bolt, ariko kubara buryo, ibisabwa, ingano yo gusaba iratandukanye cyane.Mu gishushanyo cyogosha, imbaraga-zohejuru zihuza za bolt zerekana imbaraga ntarengwa zishobora gutangwa nimbaraga zo gukata hagati yimbaraga zogosha zo hanze hamwe nubuso bwa plaque nkurugero ntarengwa, ni ukuvuga, kwemeza ko imbaraga zimbere ninyuma zihuza zidashobora kurenza imbaraga ntarengwa zo guterana mugihe cyumurimo wose.Ntaho hazabaho ihinduka ryerekana kunyerera ryisahani (icyuho cyumwimerere kiri hagati yimigozi nurukuta rwumwobo ni burigihe bikomeza) .Mu kogosha igishushanyo, ubwoko bwumuvuduko mwinshi imbaraga zihuza zemewe mumashanyarazi yo hanze arenze imbaraga ntarengwa zo guterana, ugereranije kunyerera hagati ya plaque ihujwe, kugeza igihe bolt ihurira nurukuta rwumwobo, hanyuma ugahuza kumashanyarazi ya bolt nigitutu kumwobo urukuta hamwe no guterana amagambo hagati yubusabane bwimbaraga zihuriweho, amaherezo yogosha cyangwa igitutu cyangiritse kurukuta nkuko byemerwa no kugabanya imipaka.Mu magambo make, ubwoko bwo guterana bwimbaraga zikomeye hamwe nubwikorezi bwumuvuduko mwinshi mubyukuri. i ubwoko bumwe bwa bolts, ariko igishushanyo ni
Kunyerera ntibisuzumwa.Ubwoko bwubwoko bukomeye imbaraga zidashobora kunyerera, bolt ntishobora kwihanganira imbaraga zogosha, iyo imaze kunyerera, igishushanyo gifatwa nkikigera kuri reta yananiwe, ugereranije ikuze mubuhanga; na bolts nayo ifite imbaraga zo gukata. Ibyangiritse byanyuma bihwanye nibisanzwe (bolt shear cyangwa icyuma gisya ibyuma) .Ku buryo bwo gukoresha:
Ihuza rya bolt ryumunyamuryango wingenzi winyubako yubatswe muri rusange ikozwe mumashanyarazi akomeye.Ibisanzwe bisanzwe birashobora kongera gukoreshwa, imbaraga zikomeye ntizishobora kongera gukoreshwa.Imbaraga zikomeye zikoreshwa muburyo buhoraho.
Imbaraga zikomeye ni bolts zubahwa, ubwoko bwubwikanyize hamwe na torque wrench kugirango ushyire icyubahiro cyateganijwe, ubwoko bwumuvuduko wikuramo umutwe wa plum.Ibisanzwe bisanzwe bifite imikorere mibi yo gukata kandi birashobora gukoreshwa mubice byubatswe byubatswe.Ibisanzwe bisanzwe bigomba gukomera gusa.
Ibisanzwe bisanzwe mubyiciro 4.4, icyiciro 4.8, icyiciro 5.6 nicyiciro 8.8.Imbaraga zikomeye ni 8.8 na 10.9, murizo 10.9 ninshi.
8.8 nicyiciro kimwe na 8.8S.Imikorere yubukanishi nuburyo bwo kubara bwa bolt isanzwe hamwe nimbaraga zikomeye ziratandukanye. Guhangayikishwa nimbaraga zikomeye ni mbere ya byose binyuze muburyo bwo kwiyitirira P imbere, hanyuma hanyuma Kurwanya ubushyamirane hagati yubuso bwibice bihuza kugirango bitware umutwaro wo hanze, kandi ibisanzwe bisanzwe bitwara umutwaro wo hanze.
Ihuza ryinshi rya bolt ihuza ifite ibyiza byubwubatsi bworoshye, imikorere myiza yubukanishi, kudacika intege, kurwanya umunaniro, no munsi yumurimo wumutwaro ufite imbaraga, nuburyo bwo guhuza ibyiringiro.
Imbaraga nini cyane ni ugukoresha umugozi udasanzwe kugirango ushimangire ibinyomoro, kugirango bolt itange umusaruro munini kandi ugenzurwa, ukoresheje ibinyomoro hamwe nisahani, kugirango uhuze nubwinshi bwimyitozo ngororamubiri.Mu bikorwa bya pre-pression , imbaraga nyinshi zo guterana zizabyara hejuru yubuso bwahujwe. Biragaragara, mugihe cyose imbaraga za axial ziri munsi yizo mbaraga zo guterana amagambo, umunyamuryango ntazanyerera kandi ihuriro ntirizangirika. Iri ni ihame ryo gukomera-gukomera.
Imbaraga nyinshi bolt ihuza biterwa nimbaraga zo guterana hagati yimiterere ihuza ibice bihuza kugirango wirinde kunyerera. Kugirango habeho imbaraga zihagije zo guterana hejuru yumubonano, birakenewe kongera imbaraga zo gufatana hamwe na coefficient de friction yo guhuza abanyamuryango.Imbaraga zo gufatana hagati yabanyamuryango zigerwaho no kwitwaza kuri bolts, bityo bolts igomba bikozwe mubyuma bikomeye cyane, niyo mpamvu bitwa imbaraga-zikomeye za bolt.
Mumuvuduko mwinshi wa bolt ihuza, coefficient de fraisse igira uruhare runini mubushobozi bwo kwifata.Ikizamini cyerekana ko coefficient de fraisation yibasiwe cyane cyane nuburyo bwo guhuza ibintu hamwe nibikoresho bigize. Kugirango twongere coefficente ya friction yubuso bwitumanaho , uburyo nko guturika umucanga no gusukura insinga zikoreshwa muburyo bwubwubatsi kugirango bivure ubuso bwibice bigize urwego.
