Cov Txheej Txheem Kho Mob Kub ntawm Cov Bearing: Xyuas kom meej thiab ruaj khov

Yuav ua li casLub zog hloov pauvMuab Kev Ua Tau Zoo Rau Kev Ua Lag Luam Thoob Ntiaj Teb

Bearings yog cov khoom tseem ceeb siv dav hauv tsheb, tsheb lag luam,cov tshuab ua liaj ua teb, cov khoom siv hauv kev lag luam, thiab lwm yam tshuab. Lawv lub luag haujlwm tseem ceeb yog txo qhov kev sib txhuam thiab txhawb nqa cov khoom tig, uas cuam tshuam ncaj qha rau kev ua haujlwm zoo, kev ruaj khov, thiab lub neej ua haujlwm. Ntawm txhua txoj kev tsim khoom, kev kho cua sov ntawm cov hlau bearing ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab txog kev ua haujlwm ntawm bearing thiab kev ntseeg tau.

At Lub zog hloov pauv, nrog ntau tshaj 20 xyoo ntawm kev paub txog kev tsim khoom thiabcov khoom siv tom qab kev lag luam tsheb, kev kho cua sov yog suav tias yog ib qho txheej txheem tswj xyuas zoo tseem ceeb kom ntseeg tau tias muaj kev ua tau zoo tas mus li, lub neej ua haujlwm ntev, thiab kev ruaj khov ntawm cov khoom thoob ntiaj teb.

Vim Li Cas Kev Kho Mob Kub Thiaj Tseem Ceeb Rau Kev Ua Haujlwm ntawm Bearing

Cov hlau bearing, feem ntau yog cov hlau chromium uas muaj cov pa roj carbon ntau, muaj qhov nyuaj thiab tsis kam qaug zog hauv nws cov xwm txheej raws li dov lossis forged. Hauv cov chaw ua haujlwm tiag tiag, cov bearings raug rau kev kub ceev, kev thauj khoom hnyav, thiab kev ntxhov siab ntau zaus. Yog tsis muaj kev kho cua sov kom zoo, cov bearings yuav yooj yim hnav, qaug zog spalling, deformation, lossis ua tsis tiav ua ntej lub sijhawm.

Kev kho cua sov hloov pauv cov qauv sab hauv ntawm cov hlau bearing los ntawm kev hloov pauv austenite mus rau hauv martensite thiab lwm yam qauv zoo tshaj plaws. Qhov kev hloov pauv no ua rau muaj zog, hnav tsis kam, qaug zog, thiab tawv, ua rau cov bearings ua haujlwm tau zoo hauv qab cov xwm txheej ua haujlwm nyuaj.

Cov Txheej Txheem Kho Mob Kub rau Cov Bearings

Cov txheej txheem kho cua sov uas siv dav tshaj plaws rau cov hlau bearing suav nrog quenching, tempering, carburizing, thiab nitriding. Ntawm cov no, quenching thiab tempering yog lub hauv paus ntawm feem ntau cov txheej txheem kho cua sov bearing.

Cov txheej txheem kho cua sov txheem feem ntau muaj plaub theem tseem ceeb:

1. Kev kho cua sov ua ntej
2. Kev tua hluav taws
3. Kev ua kom sov
4. Kev kho mob tom qab cua sov

Kev Kho Mob Ua Ntej Thaum Tshav Kub: Tso Lub Hauv Paus

Kev kho ua ntej cua sov, feem ntau yog annealing lossis normalizing, yog siv los tshem tawm kev ntxhov siab sab hauv uas tsim los ntawm kev forging thiab dov. Nws kuj tseem ua kom cov qauv ntawm cov noob zoo dua, ua kom cov qauv me me sib npaug, thiab txhim kho kev siv tshuab.

Thaum lub sijhawm no, cov kabmob blanks raug cua sov kom txog li 850–950 ° C, khaws cia rau lub sijhawm tswj, thiab tom qab ntawd maj mam txias hauv lub cub tawg. Cov txheej txheem no ua kom muaj kev ruaj khov ntawm cov qauv ua ntej tua hluav taws.

Kev Tua Hluav Taws: Ua tiav Kev Nyuaj Siab thiab Kev Tiv Thaiv Kev Hnav

Kev ua kom kub yog cov txheej txheem tseem ceeb rau kev txhim kho qhov tawv ntawm cov kabmob. Tom qab kev kho ua ntej, cov kabmob blanks raug cua sov rau qhov kub austenitizing, feem ntau yog 820–860 ° C rau cov hlau chromium uas muaj cov pa roj carbon ntau. Thaum austenitized tag nrho, cov khoom siv raug txias sai sai siv cov tshuaj quenching tswj xws li roj lossis dej.

Qhov kev txias sai no tiv thaiv kev tsim pearlite thiab txhawb kev hloov pauv martensitic, ua rau muaj kev nyuaj thiab kev tiv thaiv kev hnav. Txawm li cas los xij, quenching kuj ua rau muaj kev ntxhov siab sab hauv, ua rau tom qab tempering tseem ceeb.

Tempering: Sib npaug ntawm Hardness thiab Toughness

Kev kho kom sov yog ua kom txo qhov brittleness thiab txo qhov kev ntxhov siab sab hauv thaum tswj hwm qhov nyuaj siab. Cov bearings raug rov ua kom sov rau qhov kub tsawg, feem ntau ntawm 150–250 ° C, tuav rau lub sijhawm teev tseg, thiab tom qab ntawd txias rau chav tsev kub.

Kev ua kom kub tsawg tso cai rau cov bearings kom khaws tau qhov kev tiv thaiv zoo heev thaum txhim kho kev tawv thiab kev cuam tshuam, kom ntseeg tau tias muaj kev ua tau zoo hauv kev siv tiag tiag.

Kev Kho Mob Tom Qab Kub: Txhim Kho Kev Ruaj Ntseg thiab Lub Neej Qaug Zog

Cov txheej txheem kho tom qab kub suav nrog kev txo kev ntxhov siab annealing thiab shot peening. Kev txo kev ntxhov siab annealing tshem tawm cov kev ntxhov siab seem uas tsim thaum lub sijhawm machining, ua kom ntseeg tau qhov tseeb ntawm qhov ntev thiab ruaj khov mus sij hawm ntev. Shot peening txhim kho qhov nyuaj ntawm qhov chaw thiab lub zog qaug zog los ntawm kev ua kom muaj kev ntxhov siab compressive zoo rau ntawm qhov chaw bearing.

At Lub zog hloov pauv, kev kho mob tom qab cua sov raug tswj hwm kom zoo kom ua tau raws li qhov yuav tsum tau ua ntawm tsheb, tsheb thauj khoom, tsheb laij teb, thiab cov tshuab ua liaj ua teb.

Cov Ntsiab Lus Tseem Ceeb ntawm Kev Tswj Xyuas Zoo hauv Kev Kho Mob Kub ntawm Bearing

Yuav kom ntseeg tau tias zoo sib xws, ntau yam tseem ceeb yuav tsum tau tswj hwm nruj me ntsis:

• Qhov kub thiab sijhawm ua kom sov raug thiab tiv thaiv kom tsis txhob muaj noob loj hlob lossis tsis ua tiav austenitization
• Kev ua kom txias txias zoo tshaj plaws kom tsis txhob tawg lossis tsis txaus qhov tawv
• Kev sib phim zoo ntawm qhov kub thiab txias thiab lub sijhawm nrog cov kev ntsuas quenching
• Kev tswj hwm nruj ntawm cov khoom siv huv thiab kev tua hluav taws xob zoo

Cov kev tswj no ua kom txhua tus bearings ua tau raws li cov qauv tsim thiab kev ua tau zoo.
