Niki imitwe ibiri

Ibice bibiri byumutwe bisaba ubuvuzi busanzwe, kandi hariho ubwoko bwinshi bwo kuvura hejuru yubutaka, harimo amashanyarazi, umwijima, okiside, fosifati, hamwe nubuvuzi bwa zinc butari amashanyarazi.

Nyamara, urwego rwigihugu rwa GB901 rwikubye kabiri uruganda rwibikoresho byo murugo urugo rwometseho ibyuma bifite uruhare runini mugukoresha nyabyo. By'umwihariko bikoreshwa cyane mu nganda no mu mirima nk'imodoka, ibimashini, ibikoresho byo mu rugo, ibikoresho, icyogajuru, n'itumanaho.

Ariko, kubifunga bifatanye, ntibikenewe gusa kugira ubushobozi runaka bwo kurwanya ruswa mugihe cyo gukoresha, ariko kandi no kwemeza guhinduranya insanganyamatsiko, zishobora kwitwa screw ibereye hano. Birakenewe ko hashyirwaho ibipimo byihariye bya electroplating layer kugirango huzuzwe icyarimwe ibyangombwa bibiri bisabwa kugirango birwanye ruswa kandi bisimburwe ku bifatisha imigozi mugihe cyo kuyikoresha. Uburinganire bwa GB / T5267.1-2002 GB / T5267.2-2002. Igipimo cyigihugu kuri 35CrMoa imitwe ibiri ihwanye na ISO4042 mpuzamahanga; 1999 [Amashanyarazi yometse kumashanyarazi].

Ibipimo ngenderwaho bisimbuza GB / T5267-1985 kubisanzwe bitwikiriye amashanyarazi kuri feri yiziritse.Ibiranga imitwe ibiri yimitwe ni uko bikunze gukoreshwa mubikoresho binini kandi bikwiranye n’imashini nini n’ibikoresho bizashyirwaho, nk'indorerwamo, intebe za kashe, amakadiri yo kugabanya, n'ibindi. Imbaraga-ndende ebyiri imitwe ifite ubunini bwagenwe hanyuma ushyireho ibikoresho.

Hanyuma, shyira ibinyomoro kurundi ruhande kugirango urangize kwishyiriraho. Imitwe ibiri yimitwe iroroshye kuyisimbuza, yubwiza buhebuje, kandi ni gake cyane kwambara cyangwa kwangirika, kwemerera gusenywa kubuntu.Mu gihe cyo gusana, birakenewe kugenzura imitwe mishya yashizwemo imitwe ibiri hamwe nibindi bikoresho bishya byasimbuwe, hibandwa kumutwe no kuyobora ibice byimitwe ibiri. Birakenewe kandi kugenzura neza buri gice cyurudodo kumeneka cyangwa kumeneka, no kugenzura imiterere y amenyo yimitwe ibiri yimitwe kugirango ihinduke. Hoba hariho ibintu bidasanzwe mukibuga? Niba hari ibintu bidasanzwe, ntibigomba kongera gukoreshwa. Abanyamerika basanzwe bakora imitwe ibiri ya bolt bagomba gukoresha umurongo wa torque nkigikoresho mugihe ushyiraho imipira ihuza inkoni. Birakenewe gukomera ukurikije ibipimo byateganijwe, kandi itara ntirigomba kuba rinini cyangwa rito. Ni ngombwa kandi guhitamo guhuza imitwe ibiri hamwe na sitidiyo ebyiri kuva mubakora.
