Intangiriro yo Kwizirika-2

4. Igishushanyo cya Bolt

5. Kumenyekanisha Bolt

6. Ibimenyetso, amanota yimikorere, nibindi

1. Ibimenyetso: Kumurongo wa mpande esheshatu (imigozi ya diameter> 5mm), ibimenyetso bigomba gukorwa hejuru yumutwe ukoresheje inyuguti yazamuye cyangwa yasubiwemo, cyangwa kuruhande rwumutwe ukoresheje inyuguti zasubiwemo.Ibi birimo amanota yimikorere nibimenyetso byabayikoze.Ku byuma bya karubone: Imbaraga zerekana amanota kode igizwe nimirongo ibiri yimibare yatandukanijwe na “·”.Ubusobanuro bwigice cyumubare mbere ya “·” muri kode yerekana ibimenyetso byerekana imbaraga zingana.Kurugero, “4 ″ mu cyiciro cya 4.8 yerekana imbaraga zingana zingana na 400N / mm2, cyangwa 1/100 cyibyo.Igisobanuro cyigice cyumubare nyuma ya “·” muri kode yerekana ikimenyetso cyerekana umusaruro-kuri-tensile, nicyo kigereranyo cyumusaruro utangwa cyangwa imbaraga zumusaruro wizina nimbaraga zumwanya.Kurugero, ingingo yumusaruro wibicuruzwa 4.8 ni 320N / mm2.Ibyuma bitagira ibyuma byerekana amanota agizwe nibice bibiri bitandukanijwe na “-”.Ikimenyetso mbere ya “-” muri kode yerekana ibimenyetso, nka A2, A4, nibindi. Ikimenyetso nyuma ya “-” cyerekana imbaraga, nka A2-70.

2).Icyiciro: Kubyuma bya karubone, metric bolt yamashanyarazi yamashanyarazi arashobora kugabanywamo amanota 10 yimikorere: 3.6, 4.6, 4.8, 5.6, 5.8, 6.8, 8.8, 9.8, 10.9, na 12.9.Ibyuma bitagira umwanda bigabanyijemo ibyiciro bitatu: 60, 70, 80 (austenitis);50, 70, 80, 110 (martensitike);45, 60 (ferritic).

7. Kuvura Ubuso

Kuvura hejuru cyane cyane ni ukongera imbaraga zo kurwanya ruswa, kandi bamwe na bo batekereza ibara, bityo rero ni cyane cyane kubicuruzwa byuma bya karubone, mubisanzwe bisaba kuvurwa hejuru.Ubuvuzi busanzwe bukoreshwa harimo kwirabura, gusya, gusya umuringa, isahani ya nikel, isahani ya chrome, isahani ya feza, isahani ya zahabu, dacromet, gushyushya-gushya, n'ibindi.;hari ubwoko bwinshi bwa galvanizing, nkubururu nubururu byera, zinc yubururu, zinc yera, zinc yumuhondo, zinc yumukara, icyatsi kibisi, nibindi, kandi byashyizwe mubice byangiza ibidukikije kandi bitangiza ibidukikije.Buri cyiciro gifite umubyimba mwinshi kugirango wuzuze ibisabwa byo gupima umunyu.

Incamake y'ibicuruzwa bisanzwe byimodoka

1).Incamake yimodoka isanzwe ibice

Ibice bisanzwe byimodoka bifite ubwoko butandukanye kandi bikoreshwa mubikorwa byihariye byibice bitandukanye nibice byimodoka, kimwe no guhuza no guteranya sisitemu zitandukanye kugirango ibinyabiziga byose.Ubwiza bwibice bisanzwe bigira ingaruka zikomeye kumiterere rusange no mumikorere yibikoresho bya mashini, kandi abakora ibinyabiziga mubusanzwe bafite uburyo bukomeye bwo gusuzuma no gutanga ibyemezo bya sisitemu yo gutanga byihuse.Ingano nini yisoko yinganda zitwara ibinyabiziga zitanga umwanya mugari witerambere ryibicuruzwa bisanzwe byimodoka.Nk’uko imibare ibigaragaza, imodoka yoroheje cyangwa itwara abagenzi isaba hafi ibiro 50 (hafi 5.000) byibice bisanzwe, mugihe imodoka yubucuruzi iciriritse cyangwa iremereye ikenera ibiro 90 (hafi 5.710).

2).Imodoka isanzwe Ibice

Buri ruganda rukora moteri mu nganda zikoresha amamodoka rukoresha ibisanzwe “Automotive Standard Parts Parts Products Numbers Amategeko” (QC / T 326-2013) kugirango hategurwe ibisobanuro ku bice bisanzwe by’ibigo, kandi ibirimo bikomeza kuba bimwe nubwo bitandukanye.

Ibinyabiziga bisanzwe byimibare igizwe nibice 7, murutonde:

- Igice cya 1: Ibinyabiziga bisanzwe biranga kode;
- Igice cya 2: Kode zitandukanye;
- Igice cya 3: Hindura code (bidashoboka);
- Igice cya 4: Kode yerekana ibipimo;
- Igice cya 5: Imikorere ya mashini cyangwa kode y'ibikoresho;
- Igice cya 6: Kode yo kuvura hejuru;
- Igice cya 7: Kode yo gutondekanya (bidashoboka).

Urugero: Q150B1250TF61 yerekana umutwe wa mpande esheshatu zifite umutwe wihariye wa M12, uburebure bwa 50mm, urwego rwo gukora rwa 10.9, hamwe na zinc idafite amashanyarazi (silver-gray).Uburyo bwo guhagararirwa nuburyo bukurikira:
