Ibyuma binini cyaneIcyerekezo gito cya diameter ntoya idafite icyumahafi ntabwo ikoresha inzira yo kuzimya;Mugihe ingano ya austenite yagumishijwe isabwa cyane, ibyuma bito bito ntibizimya.Ikibazo gisanzwe nukugaragara kwinyeganyeza hejuru ya aprecision ntoya ya diameter idafite umuyoboro wicyuma(nka spiral cyangwa hypoid gears) munsi yumurimo wakazi.
Kugirango ugabanye urugero rwa austenite yagumishijwe hamwe na deformasiyo mugihe cyo kuzimya mu buryo butaziguye, gukonjesha birashobora gukoreshwa kugirango wegere ubushyuhe bwa Ar1 nyuma yo gutwika hanyuma kuzimya.Umuyoboro muto wa diameter ntoya idafite icyuma nawo urashobora kuzimya mbere iyo wimuriwe mu itanura rirenze gato ubushyuhe bwa Ar1.Nyuma yo gutwika no kuzimya, umuyoboro muto wa kalibiri utagira kashe nawo urashobora gushyukwa ku bushyuhe buri hejuru ya Ac1, bikarushaho kunonosorwa ingano no kugabanya urugero rwa austenite isigaye.
Diameter ntoyaimbeho ikonje idafite icyumairazimye kugirango ubone imbaraga zisumba izindi zose, ariko gukomera ntabwo biri hejuru.Ubukomere bwurwego rwa karburize burashobora gupimwa na dosiye.Ubukomezi burashobora kugabanuka bitewe nuko hariho austenite isigaye mumashanyarazi mato mato adasobanutse yicyuma kinini.Ubu buryo burashobora kandi kugabanya sima kumupaka wingano.Mugihe cyo gutunganya karburize yubuso buto bwa kalibiriumuyoboro w'icyumabirakenewe, gukonjesha buhoro cyangwa annealing bizakirwa.
Niba ibyuma bikomeye byakomeye byatoranijwe cyangwa bigira ingaruka kubikoresho, nubwo gukonjesha bitinda, ubuso bwa diameter ntoya itomoye neza umuyoboro mwinshi wurukuta uracyafite ubukana bwinshi.Muri iki gihe, hagomba gukoreshwa uburyo bworoshye bwo kuvura.Kugira ngo wirinde imiyoboro ya karbide, hagomba gukurikizwa igipimo cyo gukonjesha giciriritse.Fata ingamba zimwe na zimwe kugirango wirinde decarburisation mugihe cyo gukonja buhoro.Ibyuma bizimya amazi bizakoreshwa nyuma.Nyuma ya carburizing, gukonjesha buhoro cyangwa uburyo bwo kuzimya amavuta birashobora gukoreshwa mugutunganya ibinyampeke hagati yumuyoboro muto wicyuma udafite ibyuma bidafite ihinduka rikomeye.
Muburyo bwo gutunganya ubushyuhe bwo kuzimya ubushyuhe bwinshi, carburizing hamwe no gukonjesha bikurikirwa no kuzimya ubushyuhe, kuzimya hejuru birashobora kugerwaho no kuzimya hejuru, kandi ubu buryo bushobora no gukoreshwa.Kubisobanuro bito bito bitagira ibyuma bifite ibyuma byinshi, nibyiza gufata inzira yuburyo bwegereye kuzimya mu buryo butaziguye, ni ukuvuga gushyushya 15 ~ 25 ℃ (25 ℃ ~ 50 ℃) hejuru yubushyuhe bwo hagati (birumvikana, kurenga impinduka zo hejuru).
Uburyo bwo gutunganya ubushyuhe bwongerera imbaraga imbaraga zintangiriro ya diameter ntoya-yuzuye neza idafite umuyoboro kandi ifite ubukana bwiza.Hafi ya karbide zose zisigaye hejuru zirashonga.Nubwo ibisigazwa bya austenite bisigaye muribwo buryo busobanutse neza diameter ntoya ikonje izengurutswe n'umuyoboro w'icyuma utari munsi yo kuzimya mu buryo butaziguye, izagumana igice.Guhindura ni binini kuruta kuzimya mu buryo butaziguye, ariko murwego rwemewe.Kimwe no kuzimya mu buryo butaziguye, ubu buryo ntibukoreshwa cyane mubyuma bisanzwe bya karubone.
Nyuma yo gukonjesha buhoro cyangwa kuzimya, ibyuma byamazi birashobora gushyukwa kugeza ubushyuhe bwo guhindura icyiciro hejuru gato ugereranije nubwa karubisi.Kurugero, umuyoboro muto wa diameter alloy precision idafite umuyoboro urashobora gushyuha nyuma yo gutwika no gukonjesha buhoro, kubera ko idashobora gutunganya ibinyampeke no kuzimya, kuburyo ubukana bwayo buri hasi, deformasiyo ni nto, kandi ubukana buringaniye;Igice cyo hejuru gifite karbide zidashonga, kuburyo gifite ubukana bwinshi nubugome;Kurugero, umuyoboro muto wicyuma udafite kashe ushyushye nyuma yo gutwika no kuzimya, kandi ingano ziratunganijwe neza.Ikigo gifite ubukana buhanitse, ubukana buke, kandi hejuru ntigira umuyoboro wa simaite, bityo ubukomere ni bwinshi kandi gukomera ni byiza, ariko ibibi ni uko deformasiyo ari nini.
