Nyob rau hauv kev lag luam bearing, lub nplhaib tawg tsis yog tsuas yog ib qho teeb meem zoo ntawm kheej kheej cov menyuam bearings, tab sis kuj yog ib qho teeb meem zoo ntawm txhua hom bearings. Nws tseem yog daim ntawv tseem ceeb ntawm bearing nplhaib tawg. Qhov laj thawj yog feem ntau cuam tshuam nrog cov khoom siv raw ntawm cov kabmob. Kev sib raug zoo, ua ke nrog kev ua haujlwm tsis zoo nyob rau theem tom ntej, yuav ua rau muaj teeb meem xws li ferrule breakage thaum lub sijhawm ua haujlwm ntawm cov khoom siv. Yuav tiv thaiv li cas? Cia wb mus saib ua ke:
1. Ua ntej ntawm tag nrho cov, nruj me ntsis tswj cov ntaub ntawv raw rau kev tsim cov spherical roller bearings, tshwj xeeb tshaj yog thaum lub sij hawm ua, peb yuav tsum tshem tawm cov nkig ntsiab, carbide kua sib cais, mesh, siv, thiab lwm yam muaj nyob rau hauv cov ntaub ntawv raw. Cov yam ntxwv xws li Yog tias nws tsis raug tshem tawm, nws yuav ua rau muaj kev ntxhov siab, maj mam hnav lub zog ntawm lub nplhaib, thiab nyob rau hauv cov xwm txheej hnyav yuav ua rau lub nplhaib ntawm lub nplhaib kheej kheej rau cov kabmob ncaj qha. Ntawm no, spherical roller bearing tuam ntxhab qhia tias txhua tus neeg sim yuav cov hlau ruaj khov thiab txhim khu kev qha, thiab tsis tu ncua xyuas cov hlau cia, thiab tswj los ntawm qhov chaw, thiaj li ua kom zoo dua tom qab siv.
2. Yog hais tias muaj teeb meem xws li overburning, overheating thiab sab hauv cracking tshwm sim nyob rau hauv cov txheej txheem ntawm spherical roller bearings, nws yog feem ntau vim hais tias lub kub tswj thaum lub sij hawm forging thaum lub sij hawm ua hauj lwm tsis ruaj khov txaus, uas yuav txo tau lub toughness thiab lub zog ntawm lub ferrule. . Yog li ntawd, txhawm rau zam thiab tiv thaiv cov khoom zoo li no, nws yog ib qho tsim nyog yuav tsum nruj me ntsis tswj kev ua haujlwm kub, cua kub cua sov thiab cua kub dissipation tom qab forging. Ntawm no, spherical roller bearing manufacturers pom zoo tias cov tshuaj tsuag txias tuaj yeem siv los ua kom cov cua sov, tshwj xeeb tshaj yog rau cov menyuam bearings loj dua. Cov menyuam bearing rings muaj cov teebmeem pom tseeb. Ntawm no, nws yog ib qho tsim nyog yuav tsum tau ua tib zoo saib xyuas qhov ntsuas kub siab tshaj 700 ℃ kom ntau li ntau tau, thiab tsis muaj cov khoom yuav tsum tau khaws cia ib puag ncig.
3. Nws yog ib qho tseem ceeb heev uas yuav tsum tau ua kev kho cua sov thaum lub sij hawm ua cov txheej txheem. Ua tib zoo saib xyuas qhov kev ntseeg siab ntawm cov khoom siv kuaj. Nws yuav tsum tau kuaj ua ntej ua ntej ua. Kev ntsuam xyuas nruj yog ua thaum lub sij hawm kuaj xyuas kom ntseeg tau qhov kev ntseeg siab ntawm cov ntaub ntawv ntsuas. Cov ntaub ntawv tsis raug thiab randomness, qhov no kuj yog vim qhov lav ntawm qhov zoo ntawm cov menyuam kheej kheej tawm ntawm lub ferrule thaum lub sij hawm tag nrho cov txheej txheem kho cua sov. Ntxiv nrog rau kev tshuaj xyuas, cov txheej txheem quenching yuav tsum tau txhim kho ntxiv. Qhov no yog los daws qhov tsis xws luag ntawm loj kheej kheej cov menyuam bearing rings. Cov muaj pes tsawg leeg thiab kev ua tau zoo ntawm cov roj quenching yuav tsum tau txiav txim siab ua ntej, thiab nws yuav tsum tau siv nruj raws li qhov yuav tsum tau ua thiab hloov cov roj quenching ceev. Txhim kho qhov nruab nrab quenching los txhim kho cov xwm txheej quenching.
4. Rau qhov tiav kheej kheej cov menyuam bearing nplhaib, kev sib tsoo kub hnyiab thiab tawg yog tsis tso cai, tshwj xeeb tshaj yog qhov sib txuam ntawm lub nplhaib puab ntsia hlau tsis pub muaj qhov kub hnyiab, yog li nws yog feem ntau tsim nyog tom qab pickling. Kev tshuaj xyuas nruj yuav tsum tau ua, thiab cov khoom tsis raug yuav tsum tau muab tshem tawm. Qee qhov kub hnyiab loj uas kho tsis tau yuav tsum muab pov tseg tam sim ntawd. Burned ferrules yuav tsum tsis txhob muab tso rau hauv cov khoom siv.
5. Kuj tseem muaj cov qauv nruj rau kev txheeb xyuas cov kabmob kheej kheej kheej kheej. Thaum cov hlau yuav muab tso rau hauv qhov chaw cia, nws yuav tsum nruj me ntsis txawv ntawm GCr15 thiab GCr15SiMn, ob yam khoom thiab cov khoom sib txawv.
Ib feem ntawm cov ntaub ntawv yog los ntawm Is Taws Nem, thiab siv zog ua kom muaj kev nyab xeeb, raws sijhawm, thiab raug. Lub hom phiaj yog xa cov ntaub ntawv ntau ntxiv, thiab nws tsis txhais hais tias nws pom zoo nrog nws cov kev xav lossis lub luag haujlwm rau nws qhov tseeb. Yog tias cov ntaub ntawv rov luam tawm ntawm lub vev xaib no cuam tshuam txog kev cai lij choj thiab lwm yam teeb meem, thov hu rau lub vev xaib no kom lub sijhawm tshem tawm.
