Ibiranga ibicuruzwa
(1) Ibikoresho n'imbaraga
Ibyuma byujuje ubuziranenge: Byakozwe mubyuma byujuje ubuziranenge nka 42CrMoA, kwemeza ko bolt ifite imbaraga nyinshi nubukomezi bwiza bwo guhangana ningaruka zikomeye hamwe no kunyeganyega kwa moteri na buldozeri mu kazi gakomeye.
Icyiciro cyo hejuru cyane: amanota yingufu zisanzwe zirimo 8.8, 10.9, na 12.9. 10.9 yo mu byiciro ifite imbaraga zingana na 1000-1250MPa nimbaraga zitanga 900MPa, zujuje ibyangombwa bisabwa mumashini menshi yubwubatsi; Ibipimo bya 12.9 bifite imbaraga zo hejuru, hamwe nimbaraga zingana na 1200-1400MPa nimbaraga zitanga 1100MPa, zibereye ibice byihariye bifite imbaraga nyinshi zisabwa cyane.
(2) Igishushanyo n'imiterere
Igishushanyo mbonera: Mubisanzwe igishushanyo mbonera cyumutwe, gitanga urumuri runini rwo kwizirika kugirango bolt ikomeze gukomera mugihe cyo gukoresha kandi ntibyoroshye kurekura. Mugihe kimwe, igishushanyo mbonera cya mpande esheshatu nacyo cyoroshye mugushiraho no gusenya hamwe nibikoresho bisanzwe nka wrenches.
Igishushanyo cyinsanganyamatsiko: Urudodo rwuzuye-rusobanutse, muri rusange ukoresheje urudodo ruto, rufite imikorere myiza yo kwifungisha. Ubuso bwurudodo butunganijwe neza kugirango hamenyekane ubunyangamugayo nukuri kwinsanganyamatsiko, kunoza imbaraga zo guhuza no kwizerwa kwa bolt.
Igishushanyo cyo Kurinda: Bolt zimwe zifite ingofero yo gukingira kumutwe. Isura yo hejuru yumutwe wikingira ni ubuso bugoramye, bushobora kugabanya ubushyamirane buri hagati ya bolt nubutaka mugihe cyo gukora, kugabanya ubukana, no kunoza imikorere yimashini zicukura na buldozeri.
(3) Kuvura Ubuso
Umuti wa Galvanizing: Kugirango utezimbere ruswa yo kwangirika kwa bolt, mubisanzwe iba galvanised. Igice cya galvanised kirashobora gukumira neza ingese no kwangirika kwa bolt ahantu h’ubushuhe kandi bwangirika, byongerera igihe cya serivisi ya bolt.
Umuti wa fosifati: Bolt zimwe nazo zitwa fosifati. Igice cya fosifati kirashobora kongera ubukana no kwambara birwanya ubuso bwa bolt, mugihe kandi bizamura imbaraga zo kwangirika kwa bolt.
