Cov hom kev tawg ntawm lub nplhaib bearing yog dab tsi?

 

Qhov teeb meem feem ntau ntawm cov nplhaib bearing yog qhov tawg, thiab qhov tawg ntawm cov nplhaib bearing tuaj yeem soj ntsuam los ntawm ob qho tib si, ib qho yog qhov tawg tsis zoo, thiab qhov thib ob yog kev siv qhov tawg, uas tuaj yeem soj ntsuam feem ntau los ntawm cov teeb meem raw khoom thiab cov txheej txheem ua, thiab kev siv qhov tawg yog tshwm sim los ntawm kev hloov pauv qaug zog thiab lwm yam laj thawj.

 

Ua ntej tshaj plaws, peb tuaj yeem saib cov laj thawj ntawm kev tawg ntawm lub nplhaib bearing:

1. Thaum muaj qhov tsis zoo xws li cov khoom siv raw, xoob, cov khoom tawg lossis cov kua carbide precipitation, reticulation, banding, thiab tsis zoo sib xws thiab kev sib cais tsis raug tshem tawm lossis txhim kho hauv kev ua haujlwm, lawv yuav ua rau muaj kev ntxhov siab, ua rau lub zog ntawm lub ferrule tsis muaj zog, thiab ua rau muaj kab nrib pleb.

 

Kev daws teeb meem: Kev ntsuas tiv thaiv yog ua raws li cov khoom xa tuaj ntawm cov channel tseem ceeb, sim yuav cov hlau zoo ruaj khov thiab txhim khu kev qha, txhawb kev tshuaj xyuas cov hlau uas tau yuav hauv tsev khaws khoom, thiab kuaj xyuas nws los ntawm qhov chaw.

 

Qhov thib ob, muaj cov kab nrib pleb hauv cov txheej txheem sib tsoo

 

Kev daws teeb meem: Ua kom muaj zog saib xyuas cov txheej txheem sib tsoo, thiab lub nplhaib uas ua tiav lawm tsis pub muaj kev sib tsoo kub hnyiab thiab sib tsoo tawg, tshwj xeeb tshaj yog ntawm qhov chaw sib txuas ntawm lub nplhaib sab hauv kom hloov lub taper. Yog tias lub ferrule raug pickled, nws yuav tsum tau kuaj xyuas tag nrho, thiab cov khoom hlawv yuav tsum tau tshem tawm, thiab qhov hlawv hnyav tsis tuaj yeem kho lossis kev kho tsis tsim nyog yuav tsum tau muab pov tseg, thiab lub ferrule nrog kev sib tsoo kub hnyiab tsis pub nkag mus rau hauv cov txheej txheem sib dhos.

 

3. Kev kho cua sov tsis zoo

 

Txoj kev kho mob: Txhawm rau daws qhov teeb meem xws li cov pob mos ntawm cov nplhaib nruab nrab thiab loj, cov khoom sib xyaw thiab kev ua tau zoo ntawm cov roj quenching yuav tsum tau txiav txim siab, thiab cov uas tsis ua raws li qhov yuav tsum tau ua yuav tsum tau hloov ua ntej thiab hloov los ntawm cov roj quenching sai kom txhim kho lub peev xwm quenching ntawm cov khoom nruab nrab thiab txhim kho cov xwm txheej txias quenching. Cov txheej txheem tempering nruj. Rau cov ntau yam uas muaj ntau qhov tawg, qhov thib ob tempering yog ua tiav tom qab kev sib tsoo ntawm lub ferrule, uas tsis tuaj yeem tsuas yog ua kom ruaj khov cov qauv thiab qhov loj ntawm lub ferrule, tab sis kuj txo qhov kev ntxhov siab sib tsoo thiab txhim kho kev ua tau zoo ntawm cov txheej metamorphic sib tsoo.

 

Cov nplhaib bearing feem ntau tawg thaum siv, thiab muaj peb hom tseem ceeb, uas yog: kev tawg ntawm kev qaug zog, kev tawg ntawm kev thauj khoom ntau dhau thiab kev tawg ntawm cua sov.

 

1. Kev tawg ntawm qaug zog

 

Nyob rau hauv qhov kev hloov pauv ntawm lub nra hnyav thiab kev cuam tshuam, qhov kev ntxhov siab ntawm lub nplhaib bearing (tshwj xeeb tshaj yog lub nplhaib sab nraud) txuas ntxiv dhau qhov kev txwv ntawm lub zog qaug zog ntawm cov khoom siv, ua rau muaj kev tawg qaug zog, thiab thaum kawg cov kab nrib pleb nthuav dav mus rau qee qhov, ua rau muaj kev tawg ntawm qhov kev ntxhov siab siab tshaj plaws ntawm qhov. Nws feem ntau tshwm sim hauv thaj chaw bearing ntawm lub nplhaib sab nraud, vim tias lub nplhaib sab nraud feem ntau haum nrog lub thawv bearing ua qhov sib txawv, thiab lub thawv bearing yog ib qho hloov pauv thiab elliptical, uas yooj yim ua rau muaj kev tawg qaug zog nyob rau hauv qhov kev hloov pauv ntawm lub nra hnyav thiab kev cuam tshuam.

 

2. Kev tawg ntau dhau

 

Zoo li qhov tawg ntawm lub zog ntawm lub bearing, thaum qhov kev ntxhov siab uas ua rau lub bearing loj dua lub zog tensile ntawm cov khoom siv, nws ua rau muaj qhov tawg hauv lub nplhaib sab hauv, feem ntau yog vim kev teeb tsa tsis raug, xws li qhov kev teeb tsa ntawm lub bearing, ua rau lub nra hnyav ntawm lub bearing, ua rau lub bearing tawg vim yog qhov overload hauv zos; Tsis tas li ntawd, kev khob tsis raug thaum lub sijhawm teeb tsa ua rau lub bearing tawg thiab poob, uas kuj raug cais ua qhov tawg overload. Qhov feem ntau yog tias thaum lub bearing raug teeb tsa nrog qhov loj me cuam tshuam, kev cuam tshuam ntau dhau kuj tseem yuav ua rau lub nplhaib bearing tawg (feem ntau yog qhov cuam tshuam haum ntawm lub nplhaib sab hauv ntawm plaub-kab cylindrical bearing), thiab kev cuam tshuam loj dhau los ua rau qhov kev ntxhov siab ntawm lub nplhaib sab hauv loj dua, tshwj xeeb tshaj yog lub nplhaib sab hauv nrog cov tuab nyias nyias (thickness cross-sectional <12mm), thiab kev cuam tshuam ntau dhau feem ntau ua rau lub nplhaib sab hauv tawg axial.

 

3. Kev tawg ntawm cua sov

 

Qhov tawg ntawm qhov kub thiab txias feem ntau yog vim qhov sib txhuam ntawm qhov sib phim nrog lub ntsej muag kawg ntawm lub nplhaib kabmob, nyob rau hauv qhov kev ua ntawm lub zog axial, qhov kev sib txhuam tsim cov cua sov siab, ua rau lub ntsej muag kawg nrog rau kev kub hnyiab thiab kev hloov pauv, kev sib txhuam thiab cua sov siab ua rau muaj qhov tawg ntawm lub ntsej muag kawg ntawm lub nplhaib kabmob, qhov tawg yog tus cwj pwm los ntawm kev sib tshuam rau kev coj ua ntawm kev sib txhuam, thiab tib lub ntsej muag kawg tawg kuj muaj kev cuam tshuam ntau dua rau lub nplhaib sab hauv nrog cov tuab nyias nyias (thickness cross-sectional <12mm), tshwj xeeb tshaj yog cov khoom siv hnyav-ua haujlwm siab lossis nruab nrab-ceev dov zeb dov.

 

Kev kawm txog qhov tshwm sim ntawm lub nplhaib tawg yuav tsum tsis txhob tsuas yog xav txog qhov tsis zoo uas tsim los ntawm cov khoom siv thiab cov txheej txheem tsim khoom, tab sis kuj kawm thiab tshuaj xyuas qhov ntev ntawm cov qauv ntawm cov khoom siv bearing, cov txheej txheem ua thiab ntsuas, cov txheej txheem ua, cov xwm txheej kev pabcuam bearing thiab lwm yam.

 

1. Cov qauv ntawm cov kabmob thiab cov xwm txheej kev pabcuam. Cov qauv sib txawv yog tsim rau cov xwm txheej kev pabcuam sib txawv; Cov qauv ntawm cov khoom siv kabmob sib txawv, thiab nws cov txheej txheem ua haujlwm tsis zoo ib yam, uas kuj cuam tshuam rau nws qhov zoo.

 

2. Txhawb kev tshawb fawb txog cov txheej txheem, txhim kho cov thev naus laus zis ua khoom, txhim kho qhov zoo ntawm kev ua khoom, thiab txo qhov ua tau ntawm qhov tsis zoo hauv kev ua khoom.

 

3. Txhim kho cov txheej txheem saib xyuas kev ua haujlwm thiab txhawb kev txhim kho qhov zoo ntawm kev ua haujlwm.

 

Thaum lub zog ntawm lub nplhaib bearing loj dua lub zog tensile ntawm cov khoom siv lossis qhov kev txwv ntawm lub zog qaug zog ntawm cov khoom siv, lub nplhaib yuav tawg, thiab qhov tawg yuav nthuav dav mus rau qee qhov, ua rau muaj kev sib cais tag nrho ntawm ib feem ntawm qhov, uas hu ua kev tawg lossis tawg.
