Lub pob hlau bearing yog lub pob hlau lag luam uas siv rau cov khoom txav mus los hauv cov bearings thiab lwm yam khoom siv kho tshuab. Nws muaj cov yam ntxwv ntawm lub zog siab, tawv thiab hnav tsis kam, yog li kev tswj hwm hauv cov txheej txheem thiab cov txiaj ntsig yog qhov tseem ceeb heev. Cov hauv qab no yuav qhia txog cov txheej txheem kho cua sov thiab cov txiaj ntsig ntawm cov pob hlau bearing.
Kev kho cua sov yog hais txog ntau yam txheej txheem thev naus laus zis los ntawm kev ua kom sov thiab txias ntawm cov ntaub ntawv los hloov cov qauv kev teeb tsa thiab cov khoom ntawm cov ntaub ntawv. Cov txheej txheem kho cua sov ntawm cov kabmob hlau feem ntau suav nrog cov kauj ruam xws li tempering, quenching thiab carburizing.
Kev kho kom sov yog txheej txheem ntawm kev ua kom lub pob hlau uas tau quenched kom sov rau qee qhov kub, thiab tom qab ntawd txias nws rau lub sijhawm tsim nyog. Lub hom phiaj ntawm kev kho kom sov yog kom tshem tawm qhov kev ntxhov siab sab hauv uas tsim thaum lub sijhawm quenching, txo qhov brittleness, thiab txhim kho qhov tawv thiab plasticity. Qhov kub thiab sijhawm kho kom sov feem ntau yog txiav txim siab raws li cov khoom sib xyaw thiab cov kev xav tau ntawm lub pob hlau bearing. Qhov kub thiab sijhawm kho kom sov qis dhau lossis luv dhau, yuav ua rau muaj kev ntxhov siab ntxiv, tsis txaus tempering, cuam tshuam rau kev ua haujlwm ntawm lub pob hlau bearing; Qhov kub thiab sijhawm kho kom sov siab dhau lossis ntev dhau, nws yuav txo qhov tawv thiab hnav tsis kam. Yog li ntawd, kev tswj hwm txheej txheem ntawm kev kho kom sov yog qhov tseem ceeb heev.
Qhov thib ob, quenching yog cov txheej txheem kho cua sov tseem ceeb ntawm lub pob hlau bearing, los ntawm kev ua kom lub pob hlau bearing sov rau qhov kub tseem ceeb, thiab tom qab ntawd txias sai sai, kom nws lub cev ua martensite lossis bainite. Kev quenching tuaj yeem txhim kho qhov nyuaj thiab lub zog ntawm lub pob hlau bearing, ua rau nws tsis yooj yim hnav thiab lub neej ua haujlwm ntev dua. Cov khoom siv txias hauv cov txheej txheem quenching feem ntau yog roj, dej lossis roj, thiab cov khoom siv txias tsim nyog raug xaiv raws li qhov xav tau tshwj xeeb ntawm lub pob hlau bearing. Qhov kub quenching, qhov ceev txias thiab kev xaiv cov khoom siv txias yuav muaj feem cuam tshuam tseem ceeb rau cov qauv thiab kev ua tau zoo ntawm lub pob hlau bearing. Qhov kub siab dhau lossis qhov ceev txias dhau yuav ua rau tawg thiab deformation; Qhov kub qis dhau lossis qhov ceev txias qeeb dhau, uas yuav cuam tshuam rau qhov nyuaj thiab lub zog.
Kev ua kom tawv yog ib qho txheej txheem uas siv ntau los ua kom tawv nto, los ntawm kev muab lub pob hlau ntsaws rau hauv cov khoom uas muaj cov pa roj carbon rau kev kho cua sov, kom cov pa roj carbon nkag mus rau hauv lub pob hlau, ua rau nws tawv thiab tiv taus kev hnav. Qhov kub, lub sijhawm ntawm kev ua kom tawv thiab kev xaiv cov khoom siv ua kom tawv muaj cov teebmeem tseem ceeb rau qhov tuab thiab qhov tawv ntawm cov txheej ua kom tawv. Qhov kub siab dhau lossis lub sijhawm ntev dhau yuav ua rau muaj kev nkag mus, qhov kub qis dhau lossis lub sijhawm luv dhau yuav cuam tshuam rau qhov zoo thiab cov teebmeem ntawm cov txheej ua kom tawv.
Qhov cuam tshuam ntawm kev kho cua sov ntawm cov pob hlau bearing feem ntau yog soj ntsuam los ntawm qee qhov ntsuas kev ua tau zoo, xws li qhov nyuaj, hnav tsis kam, tawv thiab lwm yam. Qhov cuam tshuam zoo tshaj plaws ntawm kev kho cua sov yuav tsum yog qhov nyuaj nruab nrab, hnav tsis kam zoo, thiab xav txog qhov tawv kom ntseeg tau tias lub neej thiab kev ntseeg siab ntawm cov pob hlau bearing thaum siv.
Kev ua kom zoo dua thiab tswj cov txheej txheem kho cua sov thiab cov teebmeem xav tau cov khoom siv thiab thev naus laus zis siab heev, nrog rau cov neeg ua haujlwm paub dhau los. Hauv kev tsim khoom tiag tiag, nws tseem tsim nyog los kho thiab ua kom zoo dua raws li cov khoom siv thiab cov txheej txheem tshwj xeeb kom ntseeg tau tias qhov zoo thiab kev ua tau zoo ntawm cov pob hlau bearing ua tau raws li cov qauv thiab cov neeg siv khoom xav tau.
