Ikwigishe kumenya ibikoresho by'ingenzi bya bolts mu kanya gato

Bolt ni ibice bisanzwe bya mekanike, bikunze gukoreshwa ahantu henshi, ni ku mutwe no ku ruzingo ibice bibiri by'itsinda ry'ibifunga, bigomba gukoreshwa hamwe na nut, ahanini bikoreshwa mu guhuza ibice bibiri n'imyobo inyuramo. Wenda ntusobanukiwe neza ibikoresho by'urwego rw'umugozi, iyi nkuru izakwereka ibikoresho by'urwego rw'umugozi, ubumenyi bujyanye n'urwego, kugira ngo abantu benshi bamenye kumenya imiterere mito y'umugozi.

Ingano n'ibikoresho by'imigozi bivuga iki?

Icyiciro cya bolt bivuze ko bolt ari 4.8, 8.8, 10.9 n'ikindi cyiciro cya bolt.

Ibikoresho bivuga ko bolt ikozwe mu bikoresho nk'ibi bikurikira: Q235, 35K, 40Cr, 45 # icyuma, 35CrMo icyuma, 304 stainless steel na 316 stainless steel n'ibindi.

Ingano ya bolt n'ibikoresho ni isano runaka, icyuma cyoroshye gishobora gusa gukora bolts zo mu rwego rwo hasi, icyuma cya karuboni giciriritse gishobora gukora bolts zo mu rwego rwo hagati, icyuma cya karuboni kinini, icyuma cya alloy gishobora gukora bolts zo mu rwego rwo hejuru. Ingano imwe ya bolt igaragaza imiterere ya shimi ijyanye nayo n'imiterere ya mekanike, ariko kandi ikagaragaza ibikoresho.

Dore urutonde rw'ibipimo bisanzwe by'amaboliti ashobora kuba ibikoresho. Urwego rwa 4.8 rushobora kuba Q235, Q195 n'ibindi bikoresho by'icyuma cyoroshye. Urwego rwa 5.8 Q235 hejuru y'ibindi bikoresho byose rushobora kuba, ntabwo rukeneye ubushyuhe. Udupira tw'umugozi 8.8 twa 16MM cyangwa munsi yabyo, 35 # ubuvuzi bw'ubushyuhe bwo gukonjesha, 16mm cyangwa irenga, 45 # n'ubw'icyuma cyo gukonjesha gito cya karuboni. Urwego rwa 10.9 rw'icyuma cyo gukonjesha cyo hagati cya karuboni Ubushyuhe 35Crmo 40Cr n'ibindi.

Ese imigozi ikomeye cyane ishobora gutandukanywa n'imigozi isanzwe bitewe n'ibikoresho byayo?

Muri rusange igabanyijemo ibice hakurikijwe urwego rw'imbaraga.

Urwego rw'imikorere ya bolt ni 3.6, 4.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9, 12.9 n'ibindi birenga 10, muri byo harimo bolt 8.8 no hejuru yayo zikozwe mu cyuma gikozwe mu cyuma gikozwe mu buryo bwa karuboni nke cyangwa icyuma gikozwe muri karuboni iciriritse kandi gishyushye (cyazimye, gishyushye), kizwi cyane nka bolts zikomeye cyane, ibindi bizwi cyane nka bolts zisanzwe. Ikirango cy'imikorere ya bolt gifite ibice bibiri by'imiterere ya digitale, uko bikurikirana, ni ukuvuga imbaraga zo gukurura agaciro k'ibikoresho bya bolt n'agaciro k'imbaraga zo guhindagurika.

Urugero, bolts zo mu rwego rw'imikorere za 8.8, ibisobanuro ni ibi bikurikira:

1, imbaraga zo gukurura ibikoresho bya bolt zingana na 800MPa;

2, igipimo cy'imbaraga z'umusaruro w'ibikoresho bya bolt cya 0.8;

3, imbaraga z'umusaruro w'ibikoresho bya bolt kugeza kuri 800 × 0.8 = urwego rwa 640MPa rw'amabolt akomeye cyane akoreshwa cyane ku rwego rwa 8.8 na 10.9, amabolt asanzwe akoreshwa cyane ku rwego rwa 4.8.
