Bearings ua lub luag haujlwm tseem ceeb hauv ntau lub tshuab, thiab txhawm rau tswj hwm lawv txoj haujlwm kom muaj txiaj ntsig mus sij hawm ntev, cov khoom ntawm cov kabmob feem ntau raug xaiv los ntawm cov kabmob hlau uas nyuaj dua thiab muaj kev tiv taus zoo, tab sis rau cov neeg hlau tsim, feem ntau sivhla cov menyuam bearingsyuav tsum muaj kev coj ua siab dua thiab ua kom tawv tawv.
1. Cov khoom siv rau kev coj tus kheej
Cov khoom siv dav dav yogGCr15, yoghigh-carbon chromium-bearing steelnrog cov ntsiab lus alloy tsawg, kev ua tau zoo, thiab kev thov dav. Tom qab quenching thiab tempering, nws muaj qhov siab thiab zoo ib yam tawv, hnav zoo tiv taus, thiab kev tiv tauj siab ua tau zoo. Cov hlau muaj qhov nruab nrab txias ua haujlwm yas, ua haujlwm dav dav txiav, ua haujlwm tsis zoo, ua siab zoo rau kev tsim cov pob dawb, thiab npau taws. Nws cov tshuaj lom neeg muaj: C: 0.95-1.05, Mn: 0.25-0.45, thiab Si: 0.15-0.35.
GCr15 cov kabmob hlau muaj qhov ua tau zoo tag nrho, kev txiav tau zoo tom qab txhim kho kev txhim kho, siab thiab tsis sib xws tom qab quenching thiab kub, hnav siab tiv taus thiab tiv tauj lub zog qaug zog, ua haujlwm zoo ua kom sov, muaj cov khoom sib xyaw tsawg dua, thiab pheej yig dua, tab sis nws tsis haum rauhla cov menyuam uas tau siv rau neeg hlau.
2. Cov khoom siv rau cov menyuam hla hla
Hla cov menyuam cov kabmob feem ntau siv GCr15SiMn cov hlau, uas muaj qhov hnyav dua tiv taus thiab tawv dua GCr15, qhov nruab nrab txias ua haujlwm yas deformation, tsis zoo weldability, rhiab rau qhov dawb tsim, thiab npau taws me ntsis thaum kho cua sov. Nws yog qhov tsim nyog rau kev tsim cov ntoo khaub lig rau cov menyuam sib tw nrog phab ntsa tuab ≥ 12mm thiab txheej sab nrauv ≥ 250mm thiab cov menyuam uas muaj txoj kab uas hla ≥ 22mm.
GCr15SiMncov kabmob hlau, ua cov khoom tseem ceeb rau cov menyuam hla cov menyuam, yog cov pa roj carbon siab, siab-chromium-bearing steel. Nws muaj qhov ua haujlwm siab dua thiab ua kom tawv dua li GCr15 hlau. Qhov tseem ceeb quenching txoj kab uas hla nyob rau hauv cov roj yog 90 ~ 110mm (ntim feem ntawm 50% martensite), tom qab 840 ° C roj quenching, tempered ntawm 350 ° C, thiab tom qab ntawd lub teeb quenched, cov tawv hardness yog siab li 1096HV, thiab txheej tawv qhov tob tuaj yeem ncav cuag 1 hli. Hauv qhov pom ntawm qhov tsis txaus ntawm txheej txheem kho cua sov ntawm txoj kev ua rau cov menyuam, sab nyias yog ua ntej txias thiab txias kom tsim cov khoom tsis hloov pauv, ua rau troostite lossis sorbite, ua kom muaj zog, txo kev ntxhov siab, thiab tom qab ntawd ua kom tag nrho ua tau raws cov txheej txheem xav tau. Kev kho dej txias tuaj yeem txhim kho qhov ruaj ntseg ntawm cov menyuam hla cov menyuam, lossis martensite cov qib quenching kom ruaj khov khaws cia austenite thiab tau txais qhov siab ruaj khov thiab siab tawv. GCr15SiMn cov kabmob hlau feem ntau tsis pom zoo rau forging, nws feem ntau yog siv tom qab quenching thiab kub kub.
3. Lwm cov ntaub ntawv rau cov kabmob
Ntxiv rau GCr15 cov kabmob hlau thiab GCr15SiMn cov kabmob hlau rau hla cov menyuam cov kabmob,GCr6bearing steel thiabGCr9cov kabmob hlau feem ntau siv hauv kev tsim cov kabmob. GCr6 cov kabmob hlau ntau dua ua rau ntsuas cov cuab yeej, thaum GCr9 cov kabmob hlau feem ntau yog siv los ua cov hlau hlau thiab cov menyuam.
Lub zog tawv, tawv thiab hnav tsis kam ntawm GCr6 cov kabmob hlau siab dua li cov cuab yeej carbon, thiab qhov hloov pauv me me thaum kho cua sov tsis loj. Dav siv los ntsuas cov cuab yeej, xws li cov qauv, khoom seem, cov qauv ntsuas, ntsuas, ntsuas ntsuas, ntsuas lub nplhaib, ntsuas ntsaws ntsaws, thiab ntsuas kab, thiab lwm yam. txias taub hau tuag, nrog rau cov cuab yeej siv nrawm nrawm txiav.
GCr9 cov kabmob hlau muaj qhov ua haujlwm hnyav dua thiab ua kom tawv dua li GCr6 cov kabmob hlau, ua haujlwm tau zoo, ua kom lub cev txias txias me me, tsis tuaj yeem ua haujlwm tsis zoo, thiab muaj kev nkag siab ntau ntxiv rau qhov tsim cov pob dawb. Kev kho cua sov muaj qhov nyiam ua rau npau taws. Nws tsuas yog siv los tsim cov hlau hlau nrog txoj kab uas hla ntawm 13.5-25.4mm, cov kab sib dhos sib dhos nrog txoj kab uas hla ntawm 10.3-18.5mm, lub tog raj kheej kheej kheej nrog txoj kab uas hla ntawm 9.4-17.2mm, thiab cov menyuam kheej kheej nrog txoj kab nruab nrab ntawm 9.2-17.1mm.
Cov khoom siv ntawm cov menyuam hla tau muaj qhov hnyav dua tiv taus thiab tawv dua li cov kabmob zoo tib yam, thiab los ntawm cov txheej txheem tshwj xeeb, nws tuaj yeem ua tau zoo dua kom ntseeg tau nws qhov kev ruaj ntseg, yog li nws tau siv dav los ntawm cov neeg hlau. Luoyang Tedin Bearing Co., Ltd. yog cov chaw tsim khoom lag luam uas feem ntau tsim cov ntu nyias hla hla cov menyuam rau cov neeg hlau thiab txo kev sib raug zoo. Peb muaj kev paub nplua nuj hauv kev tsim khoom thiab tsim khoom. Peb cov khoom tau siv dav hauv cov neeg hlau tsim khoom, cov cuab yeej siv kho mob thiab aerospace, thiab lwm yam lag luam uas muaj qhov xav tau siab.
