Icyiciro cya 8.8 Bolts irwanya ubushyuhe bwinshi?
Icyiciro cya 8.8 Bolt ni ubwoko bukoreshwa cyane bwimbaraga-yihuta, cyane cyane mubwubatsi, ibinyabiziga, hamwe nibikorwa rusange byubwubatsi kubera imbaraga zizewe kandi biramba.
Ibiranga
1. Ibikoresho.
2. Ibikoresho bya mashini:
- Imbaraga za Tensile: Icyiciro 8.8 Bolt ufite imbaraga zingana zingana na 800 N / mm² (800 MPa).
- Imbaraga Zitanga: Imbaraga zumusaruro, aribwo ingingo ya bolt izatangirira guhinduka muburyo bwa plastiki, ni byibuze 640 N / mm² (640 MPa), ni 80% byimbaraga zikaze.
- Kurambura: Ijanisha rirambuye ni 15%, byerekana ubushobozi bwibikoresho byo kurambura mbere yo kumeneka.
3. Igishushanyo mbonera.
4. Kurangiza Ubuso: Ukurikije ibyasabwe, Icyiciro cya 8.8 gishobora kuza hamwe nubuso butandukanye burangiye, harimo ibishishwa bya galvanised, plaque zinc, cyangwa ubundi buryo bwo kurwanya ruswa kugirango byongere igihe kirekire mubidukikije.
Icyiciro cya 8.8 Bolts irwanya ubushyuhe bwinshi?
Icyiciro cya 8.8 Bolt bifite imiterere yubukanishi kumikoreshereze isanzwe yubushyuhe (muri rusange munsi ya 100 ° C), ariko imikorere yabo irashobora kugira ingaruka mugihe ubushyuhe burenze urugero runaka. Mubisanzwe, Icyiciro cya 8.8 gishobora gukomeza imbaraga zabo hafi ya 150 ° C, ariko imbaraga zabo zirashobora kugabanuka cyane mugihe ubushyuhe buzamutse. Byongeye kandi, gukoresha igihe kirekire mubushyuhe bwo hejuru burashobora gutera Creep, Oxidation cyangwa ibindi bintu bitesha agaciro ibintu, ibyo nabyo bigira ingaruka kumyizerere nubuzima bwa serivisi ya bolts. Niba bolts ikeneye gukoreshwa mubushyuhe bwo hejuru, Bolt ifite amanota menshi (nka 10.9 cyangwa 12.9) mubisanzwe iratoranywa, cyangwa ibikoresho byabugenewe bidasanzwe birwanya ubushyuhe nkibyuma birwanya ubushyuhe, ibyuma bitagira umuyonga cyangwa nikel ishingiye kuri nikel bikoreshwa mugukora ibihingwa kugirango barebe ko bikomeza imbaraga zihagije nubutumburuke mubushyuhe bwinshi.
Muri make, 8.8 yo mu byiciro ifite ubushobozi runaka bwo guhangana nubushyuhe bwo hejuru, ariko iyo irenze ubushyuhe bwabyo, birasabwa guhitamo ibikoresho byiza hamwe n amanota ya bolt.
PASTOR yibanda ku musaruro wibikoresho bisobanutse neza nka Screws, Bolts, Nuts, Wamesa, Rivets, Inkoni Yumutwe, Imisumari, Anchors nibikoresho, nibindi. Niba ushishikajwe no gufatisha, nyamuneka twandikire kugirango umenye amakuru menshi.
