Insimbi enensimbi isetshenziswa ikakhulukazi ukwenza izinto ezigoqayo namasongo ama-rolling bearings.Ngoba ukuthwala kufanele kube nempilo ende, ukunemba okuphezulu, isizukulwane sokushisa esiphansi, isivinini esikhulu, ukuqina okuphezulu, umsindo ophansi, ukumelana nokugqoka okuphezulu, njll., insimbi ethwala kufanele ibe: ukuqina okuphezulu, ubulukhuni obufanayo, umkhawulo ophezulu wokunwebeka, ukukhathala kokuxhumana okuphezulu Amandla, ukuqina okudingekayo, ukuqina okuthile, ukumelana nokugqwala kumafutha omkhathi.Ukuze kuhlangatshezwane nezidingo zokusebenza ezingenhla, izidingo zokufana kokwakheka kwamakhemikhali ensimbi ethwalayo, okuqukethwe kanye nohlobo lokufakwa okungeyona insimbi, ubukhulu nokusabalalisa kwe-carbides, kanye ne-decarburization kuqinile.I-Bearing steel ngokuvamile ithuthukela kukhwalithi ephezulu, ukusebenza okuphezulu kanye nezinhlobo eziningi.Insimbi enensimbi ihlukaniswe yaba yinsimbi ephezulu ye-carbon chromium, insimbi ene-carburizing, insimbi enezinga lokushisa eliphakeme, insimbi engenasici kanye nezinto ezikhethekile zokuthwala ngokwezici kanye nemvelo yesicelo.Ukuze kuhlangatshezwane nezidingo zokushisa okuphezulu, isivinini esikhulu, umthwalo omkhulu, ukumelana nokugqwala kanye nokumelana nemisebe, uchungechunge lwezinsimbi ezintsha ezithwalayo ezinezakhiwo ezikhethekile zidinga ukuthuthukiswa.Ukuze kuncishiswe okuqukethwe komoyampilo kwensimbi ethwalayo, ubuchwepheshe bokuncibilikisa bokuthwala insimbi njengokuncibilikisa i-vacuum, i-electroslag remelting, kanye ne-electron beam remelting.Ukuncibilika kwenani elikhulu lezinsimbi ezithwele kuye kwathuthukiswa kusukela ekuncibilikisweni kwesithando se-arc sikagesi kuya ezinhlotsheni ezihlukahlukene zeziko lokuncibilikisa eliyinhloko kanye nokucwengisiswa kwesithando somlilo sangaphandle.Njengamanje, insimbi ethwalayo enamandla angaphezu kwamathani angama-60 + LF / VD noma i-RH + i-casting eqhubekayo + izinqubo zokugoqa eziqhubekayo isetshenziselwa ukukhiqiza insimbi ethwalayo ukuze kuzuzwe inhloso yekhwalithi ephezulu, ukusebenza kahle okuphezulu nokusetshenziswa kwamandla aphansi.Mayelana nenqubo yokwelapha ukushisa, isithando somlilo esingaphansi kwemoto kanye nesithando somlilo sithuthukiswe saba yindawo yokushisa elawulwa ngokuqhubekayo yokwelapha ukushisa.Njengamanje, uhlobo lwesithando somlilo esiqhubekayo sokushisa ukushisa lunobude obuyi-150m, futhi isakhiwo se-nodular sensimbi ethwala sizinzile futhi sifana, isendlalelo se-decarburization sincane, futhi ukusetshenziswa kwamandla kuphansi.

I-Bearing steel kufanele ibe nezinto ezilandelayo:

1. Amandla okukhathala okuxhumana aphezulu.
2. High ukumelana nemihuzuko.
3. Umkhawulo wokunwebeka okuphezulu namandla okukhiqiza.
4. Ukuqina okuphezulu nokufana.
5, ukuqina komthelela othile.
6. Ukuzinza okuhle kwe-dimensional.
7, ukusebenza okuhle kokuvimbela ukugqwala.
8. Ukusebenza kahle kwenqubo.

Ukuthwala insimbi izinto ezivamile:

Ukukhethwa kwezinto ezithwala insimbi nakho kudinga ukuthenga okuthile.Okwezinto ezithwalayo ezisebenza ngaphansi kwezimo ezikhethekile, ngokwezidingo zazo ezithile, kufanele futhi zibe nezakhiwo ezikhethekile ezihambisana nezimo zazo, njengokuthi: ukumelana nokushisa okuphezulu, ukumelana nokushisa okuphansi, ukumelana nokugqwala, I-Anti-radiation, i-anti-magnetic kanye ezinye izici.

Insimbi eqinile eqinile ngokuyinhloko iyinsimbi ephezulu ye-carbon chromium, efana ne-GCr15, enokuqukethwe kwekhabhoni okungaba ngu-1% kanye ne-chromium ecishe ibe ngu-1.5%.Ukuze kuthuthukiswe ubulukhuni, ukumelana nokuqina nokuqina, amanye ama-silicon, i-manganese, i-molybdenum, njll., njenge-GCr15SiMn, yengezwa ngokufanelekile.Lolu hlobo lwensimbi enezinsimbi lunomphumela omkhulu kunayo yonke, lubala ngaphezu kwama-95% azo zonke izinto ezikhiqizwayo zensimbi.

Insimbi ene-Carburizing i-chromium, i-nickel, i-molybdenum alloy structural steel enokuqukethwe kwekhabhoni okungu-0.08 kuya ku-0.23%.Ingaphezulu lengxenye ethwalayo i-carbonitrided ukuthuthukisa ubulukhuni bayo nokumelana nokugqoka.Le nsimbi isetshenziselwa ukukhiqiza ama-Bearings Amakhudlwana athwala imithwalo enamandla, njengama-bearings amakhulu aginqikayo, ama-auto bearing, ama-bearing machine, nama-bearings ezimoto zikaloliwe.

Izinsimbi ezithwala i-stainless zihlanganisa izinsimbi ezithwala i-carbon chromium ezingenasici eziphezulu, ezifana ne-9Cr18, 9Cr18MoV, nezinsimbi ezingenasici ze-carbon chromium, ezifana ne-4Cr13, njll., ezisetshenziselwa ukwenza ama-bearings angenabala futhi angagqwali.

Insimbi enezinga lokushisa eliphezulu isetshenziswa ekushiseni okuphezulu (300 ~ 500 ℃).Kudingeka ukuthi insimbi ibe nobulukhuni obuthile obubomvu nokumelana nokugqoka ekushiseni kokusetshenziswa.Iningi lazo lisebenzisa izisetshenziswa zensimbi zamathuluzi esivinini esikhulu, njenge-W18Cr4V, W9Cr4V, W6Mo5Cr4V2, Cr14Mo4 kanye ne-Cr4Mo4V.
