Iterambere ry'ibikoresho byo kuzunguruka

 

In icyuma gizungurukaInganda, imiterere y'ibikoresho bigena mu buryo butaziguye igihe icyuma gikoreshwa, uburyo cyizewe, n'imiterere y'imikorere yacyo. Muri iki gihe, ibice bikoreshwa biracyakorwa ahanini mu byuma bikoresha chromium nyinshi ya karuboni, nka GCr15 na GCr15SiMn bisanzwe. Mu myaka ya vuba aha, hamwe n'iterambere ry'ibikoresho bigamije umuvuduko mwinshi, imitwaro iremereye, ubushyuhe bwinshi, n'imiterere igoye yo gukoresha, ibikoresho bikoreshwa bihora bivugururwa, ahanini bigaragaza icyerekezo gikurikira cyo gukora:

 

1. Icyuma gifata neza cyane

 

Kugira ngo habeho ibyo ibice binini kandi binini by’inkuta, inganda zagiye ziteza imbere ibyuma bikomera cyane, nka GCr15SiMo na GCr18Mo. Ibi bikoresho bishobora kugira imiterere imwe ikomeye ku bipimo binini, bikanoza imbaraga n’igihe cy’umunaniro w’ibice, kandi bikwiranye n’ibyuma binini n’ibikoresho bikomeye.

 

2. Icyuma gikonjesha hejuru

 

Icyuma gikonjesha cyo hejuru cya GCr4 gikunze gukoreshwa mu bikoresho bikomeye nka gari ya moshi n'inganda zikora imiyoboro. Hakoreshejwe ubushyuhe buciriritse no gukonjesha vuba, urwego rukomeye rw'ubujyakuzimu runaka rushobora gukorwa ku buso bw'ibice, bigatuma uburebure bw'ubuso bukomera cyane kandi bukagira imbaraga nyinshi, bityo bikanoza ubudahangarwa bw'umunaniro no kudakora neza.

 

3. Ubwoko bushya bw'ibyuma bitagira umugese

Ibyuma bisanzwe bitagira umugese nka 9Cr18 na 9Cr18Mo (440C) bifite ubushobozi bwo kurwanya ingese, ariko bikunze gukora karubide zikomeye, bigira ingaruka ku mibereho y'umunaniro n'ubwiza bw'ubuso. Ibyuma bitagira umugese bya martensitic 0.7C-13Cr byavumbuwe mu myaka ya vuba aha, binyuze mu kugabanya ingano ya karuboni na chromium no kugabanya karubide za eutectic, birushaho kunoza imikorere y'umunaniro, gukomera, no kudakira ingese ku byuma bitagira umugese. Bikunze gukoreshwa mu byuma bitagira umugese, nka za hard drive bearing na bearing z'ibikoresho by'ubuvuzi.

 

4. Icyuma gifite imbaraga nyinshi mu byuma bikozwe mu cyuma

 

Ibyuma bikoresha GT series bearing, binyuze mu miterere myiza ya alloy, byongera imbaraga n'ubukomere bwa matrix kandi byongera uburimbane bwo gukonjesha. Bikwiriye imiterere y'ibyuma biremereye cyangwa byoroheje, bimara igihe cyiza mu gihe cy'isukura.

 

5. Icyuma gikingira umwanda

 

Mu buryo bufatika, ivumbi cyangwa uduce dusaza tw’amavuta yo kwisiga bishobora gukora uduce duto ku buso bw’amavuta, bigatera kwibanda ku muvuduko no kunanirwa vuba. Kugira ngo iki kibazo gikemuke, Ubuyapani bwakoze uruhererekane rwa TF rw’ibyuma birwanya umwanda (nka TF, HTF, STF, NTF, nibindi).

 

Mu kunoza ingano ya karuboni n'ibipimo by'ibintu bya alloy, ibikoresho bikora karubide nziza kandi byongera austenite igumaho, bityo bigabanye uburemere bw'imitsi ku nkengero z'aho ibintu bihagarara. Ubunararibonye bugaragaza ko imiringoti ikozwe mu byuma bya TF ishobora kumara igihe kirekire inshuro 4-10 mu gihe cy'imiringoti yanduye.

 

6. Icyuma gipima ubushyuhe bwinshi

Iyo imiyoboro isanzwe ya GCr15 ikoreshejwe mu bidukikije kuva kuri 100℃ kugeza kuri 200℃, "agace k'umweru keza" gakomeye gatuma byoroha ku gice cyo munsi y'ikintu, bityo bikagabanya igihe cyo gutwara. Kugira ngo iki kibazo gikemuke, hakozwe ibyuma bifite ubushyuhe bwinshi nka NTJ2 na KUJ7. Mu kongera neza ingano y'ibintu nka Cr, Si, na Mo, ikorwa ry'uduce tw'umweru byera riragabanuka, bigatuma imiyoboro igumana igihe cyiza cyo kubaho no kudahindagurika ndetse no kuri 150℃.～Ubushyuhe bwa 180°C. Ibi bikoresho bikoreshwa cyane muri moteri z'imodoka, moteri zitanga moteri, n'ibikoresho bishyushya.

 

7. Icyuma gishyushya cyane

Mu mikorere y’ubushyuhe bwinshi n’umuvuduko mwinshi nko mu kirere, ibikoresho gakondo ntibihagije. Ibyuma byo mu ntangiriro bifite ubushyuhe bwinshi nka T1, T2, T10, na M50, nubwo bifite ubukana bwinshi bw’ubushyuhe bwinshi, bifite ingano nyinshi y’ibintu bya alloy kandi bihenze cyane.

 

Mu myaka ya vuba aha, Uburayi na Leta Zunze Ubumwe za Amerika byateje imbere ibyuma bishya bikoresha ubushyuhe bwinshi, nka M50NiL, CBS1000, na RBD. Muri byo, M50NiL ni yo ikoreshwa cyane. Nyuma yo gukoresha carburide, carbides nziza zigaragara hejuru, zigatera imbaraga zisigaye zo gukanda. Uburemere bwayo bushobora kugera ku nshuro 2.5 z'uburemere bwa M50, bigatuma umuntu ananirwa cyane. Muri iki gihe, ikoreshwa cyane cyane mu bikoresho byo mu rwego rwo hejuru nka za moteri zikoresha amashanyarazi. Muri rusange, iterambere ry'ibikoresho bizingira rikomeje gutera imbere rigana ku mbaraga nyinshi, kwizerwa cyane, kurwanya umwanda, kurwanya ingese, no gukora neza mu bushyuhe bwinshi. Hamwe n'iterambere ry'ikirere, ibikoresho bishya by'ingufu, n'inganda zikora cyane, ubushakashatsi n'ikoreshwa ry'ibikoresho bishya bizingira bizakomeza kwiyongera, bitanga inkunga ikomeye ya tekiniki yo kunoza imikorere y'ibikoresho.
