Umubyimba: 6-40mm
Inzira: Ashyushye ashyushye, urubavu, ruzengurutse, alloy
Gukongoka ni izina risanzwe kubyuma bishyushye byubatswe. Icyiciro cya steel basanzwe ishyushye igizwe na HRB hamwe numusaruro muto watanga umusaruro wicyiciro. H, r, na b barayoshye, urubavu, n'utubari.
Hariho uburyo bubiri bukoreshwa mu nyongeragaciro: Imwe ni ugushyira mu bikorwa imiterere ya geometrike, no gushyira mu bikorwa ukurikije imiterere yambukiranya urubura runini hamwe n'imbavu. Ubwoko bwa II. Iri shingiranwa ryerekana ahanini imikorere yo gufata ibungaswa. Iya kabiri ishingiye ku byiciro by'imikorere (icyiciro), nk'igihugu cyanjye giteganijwe mu gihugu, Inyeshyamba ni (GB1199.-2007), ukurikije imbaraga z'imbaraga (Imbaraga za Tensile) Imbaraga za Tensile igabanijwemo amanota 3; Mu rutonde rw'inganda z'Ubuyapani (Ji SG3112), ingwate igabanyijemo ubwoko 5 ukurikije imikorere yuzuye; Mu gitabo cy'Ubwongereza (BS4461), amanota menshi y'ikigeragezo cy'ibizamini nacyo. Byongeye kandi, b'amafaranga ashobora kandi gushyirwa mu rwego akurikije imikoreshereze yabo, nk'icyuma gisanzwe cy'icyuma cyashimangiwe hamwe n'utubari twafashwe neza kandi ubushyuhe bufatwa nk'agaburiwe.
Ibipimo
1) izina rya diameter kandi risa na diameter
Diameter yizina ryibituba biturutse kuri 6 kugeza kuri 50mm, kandi isanzwe yasabye imirima yinyuguti 6, 8, 10, 12, 14, 32, 40, 40, 40, 40, 40, 40, 40, 40, 40, 40, 40, 40, 40, 40, 40, 40, 40, 40
2) Gutandukana byemewe nuburyo bwo hejuru nubunini bwa karubari
Amahame yo gushushanya ibishushanyo mbonera byibibari byibabe byurubavu byujuje ibi bikurikira:
Inguni β hagati y'urubavu runini hamwe na axis ya steel bar ntigomba kuba munsi ya dogere 45. Iyo inguni zirimo ntabwo zirenze dogere 70, icyerekezo cyimibavu yahinduwe ku mpande zinyuranye ziseba zigomba kuba zinyuranye;
Urutonde rwizina l of transbles ntirushobora kurenza inshuro 0.7 diameter yizina ryamaseri;
Inguni α hagati y'urubavu runini kandi hejuru yicyuma ntigishobora kuba munsi ya dogere 45;
Igiteranyo cyikiyaga (harimo n'ubugari bw'imbavu ndende) hagati y'impera z'imbavu zahinduwe ku mpande ebyiri zegeranye zinyenzi zidashobora kurenza 20% by'ibiti by'icyuma;
Iyo diameter yizina rya steel bar ntabwo arenze 12mm, agace kwurubavu na kivandimwe ntigomba kuba munsi ya 0.055; Iyo diameter yizina ari 14mm na 16mm, agace kwurubavu na kivandimwe ntigomba kuba munsi ya 0.060; Iyo diameter yizina iruta 16mm, agace kwurubavu na kivandimwe ntigomba kuba munsi ya 0.065. Reba kumugereka C kugirango ubare akabari kagereranijwe.
Urubavu rw'inzugi ubusanzwe dufite imbavu ndende, ariko kandi nta rubavu rwinshi;
3) Uburebure no gutandukana byemewe
a. Uburebure
Amabuye y'ibyuma asanzwe atangwa muburebure buteganijwe, kandi uburebure bwihariye bwo gutanga bugomba kwerekanwa mumasezerano;
Utubari turashobora gutangwa mu biceri, kandi buri reel agomba kuba inyeshyamba imwe, yemerera 5% yumubare wigituba muri buri cyiciro (ibitugu bibiri niba bitarenze bibiri) bigizwe na remezo bibiri. Uburemere bwa disiki hamwe na Disiki yagenwa binyuze mumishyikirano hagati yabatanga kandi umuguzi.
B, uburebure bwo kwihanganira
Gutandukana byemewe n'uburebure bw'icyuma iyo bigejejwe n'uburebure buhamye ntibiruta ± 25mm;
Iyo uburebure byibuze busabwa, gutandukana kwayo ni + 50mm;
Iyo uburebure ntarengwa busabwa, gutandukana ni -50mm.
c, kugabanuka no kurangira
Iherezo ry'akabari rigomba gufungurwa neza, kandi ubumuga bwaho ntibukwiye guhindura imikoreshereze
