Bearings Kuv ntseeg hais tias txhua tus neeg tau pom tias lub luv thij peb siv kuj muaj bearings, thiab lub tsheb uas peb nquam caij kuj muaj bearings, tab sis qhov loj thiab style ntawm tus bearings yog txawv. Tam sim no, qhov zoo tshaj bearings nyob hauv lub ntiaj teb yog SKF bearings. Yog li cas lub pob hlau nyob hauv lub SKF bearing ua? Ntau tus neeg tseem tsis paub cov txheej txheem tsim ntawm kev coj tus kheej. Lub pob zeb hauv cov kabmob yog qhov tseem ceeb heev. Yog hais tias qhov hardness tsis zoo, ces tus kabmob no yuav tsis ua haujlwm. Hauv qab no peb yuav ua kom paub cov kev paub ntawm kev sib tsoo ntawm qhov sib npaug ntawm cov pob zeb tsawg.
Kev ua cov hlau ua tshuab: Tus qauv kev sib tsoo lub pob zeb ntawm daim tawv pob zeb ntawm cov kabmob hlau pob zeb tom qab sib tsoo hauv qhov sib tsoo tshuab hu ua nyuaj sib tsoo. Qhov nws muaj nuj nqi yog los tua cov mos sib mos (los yog teeb sib tsoo) uas tsis xws luag thiab tshem tawm cov pa oxidation thaum lub sij hawm kho cov cua sov. Decarburization, deformation thiab troostite defects ntxiv txhim kho qhov tseeb thiab nto zoo. Thaum los yog tom qab sib zog sib tsoo ntawm lub pob hlau, cov qhov tsis raws qhov yuav tsum tau pom kev pom. Tom qab qhov txias txias, qhov kub hnyiab yuav tsum kuaj. Qhov kub hnyiab tuaj yeem muab faib ua ob sab kub hnyiab thiab kub nyhiab sab nraud. Qhov thib ob tempering Burns yog dub tom qab txias pickling. Tom qab ob sab quenching tom qab, tom qab txias pickling, qhov nruab nrab yog grey martensite, ncig los ntawm dub troostite. Tawm kev kub hnyiab, hnov qhov hlawv, thiab kev puas siab ntsws bipolar (pob loj loj).
Ua rau muaj kev puas siab ntsws bipolar:
1. Qee qhov tuag rov los rau ntawm lub cuab yeej twj, kom cov khoom ntawd tsis tuaj yeem tau txais qhov sib npaug ntawm qhov sib tsoo rau hauv lub npas loj, lub pob loj tsuas tig rov qab rau hauv qhov zawj, thiab tsis yog tig los ntawm ob sab npoo ntawm cov hniav sib tsoo;
2. Ib qho zawj nrawm yog thaiv los ntawm cov khoom txawv teb chaws xws li sib tsoo pob zeb thiab lub taub hau, thiab tsis pom thiab tshem tawm hauv lub sijhawm. Tom qab ntev, lub zawj yuav ua ntiav. Thaum lub pob rov qab nkag qhov zawj, muaj qhov tshwm sim kub yau tshwm sim.
