Kev sib piv ntawm cov bearings dov thiab cov bearings tiaj tus

Rau kev siv ntawmcov kabmob, cov khoom sib txhuam ntawm cov mounting bearings tuaj yeem muab faib ua dov bearings thiab swb bearings, peb tuaj yeem xaiv ntau hom bearing raws li qhov xav tau tshwj xeeb ntawm kev siv, dov bearings thiab swb bearings muaj cov yam ntxwv sib txawv ntawm kev siv,

Cov yam ntxwv tseem ceeb ntawmdov bearingsyog:

1. Kev sib txhuam me me (piv rau kev sib txhuam tsis yog kua), kev pib ua haujlwm yooj yim;

2. Nws tuaj yeem dais radial thiab axial loads tib lub sijhawm, ua kom yooj yim rau cov qauv txhawb nqa;

3. Qhov radial clearance me me, thiab qhov clearance kuj tseem tuaj yeem raug tshem tawm los ntawm txoj kev preloading, yog li qhov tseeb ntawm kev sib hloov yog siab;

4. Kev sib pauv zoo thiab kev saib xyuas yooj yim.

 

Cov yam ntxwv tseem ceeb ntawmcov kabmob tiaj tusyog:

1. Ua haujlwm ruaj khov thiab tsis muaj suab nrov;

2. Kev sib hloov siab heev;

3. Kev poob me me thaum lub sijhawm ua kua roj;

4. Qhov loj me me ntawm radial;

5. Muaj peev xwm nqa tau ntau.

 

Cov txiaj ntsig thiab qhov tsis zoo ntawm cov rolling bearings piv rau cov bearings tiaj tus yog dab tsi? Kev tshuaj xyuas yog raws li nram no:

 

Piv nrog cov bearings tiaj tus, cov bearings dov muaj cov txiaj ntsig zoo li nram no:

1. Cov coefficient ntawm kev sib txhuam ntawm cov kabmob dov yog me dua li ntawm cov kabmob swb, thiab kev ua haujlwm kis tau zoo yog siab. Feem ntau, cov coefficient ntawm kev sib txhuam ntawm cov kabmob swb yog 0.08-0.12, thaum cov coefficient ntawm kev sib txhuam ntawm cov kabmob dov tsuas yog 0.001-0.005;

2. Cov kabmob dov tau raug qauv, serialized thiab dav dav, tsim nyog rau kev tsim khoom loj thiab kev xa khoom, thiab yooj yim heev rau kev siv thiab tswj;

3. Cov kabmob dov yog ua los ntawm cov hlau bearing thiab raug kho cua sov, yog li cov kabmob dov tsis tsuas yog muaj cov khoom siv kho tshuab siab thiab lub neej ntev, tab sis kuj tuaj yeem txuag cov hlau kim dua uas tsis yog ferrous siv hauv kev tsim cov kabmob swb;

4. Qhov kev tshem tawm sab hauv ntawm lub dov bearing yog me me heev, thiab qhov tseeb ntawm txhua qhov yog siab, yog li qhov tseeb ntawm kev khiav yog siab. Tib lub sijhawm, qhov rigidity ntawm lub bearing tuaj yeem nce los ntawm kev preloading. Qhov no tseem ceeb heev rau cov tshuab precision;

5. Qee cov bearings dov tau tuaj yeem dais radial load thiab axial load tib lub sijhawm, yog li cov qauv ntawm cov kabmob bearing tuaj yeem ua kom yooj yim;

6. Vim muaj kev sib kis tau zoo thiab tsis tshua muaj cua sov ntawm cov kabmob dov, kev siv roj lubricating tuaj yeem txo qis, thiab kev lubrication thiab kev txij nkawm yooj yim dua;

7. Cov kabmob dov tau yooj yim siv rau uranium hauv txhua qhov kev taw qhia ntawm qhov chaw.

 

 

Txawm li cas los xij, txhua yam yog muab faib ua ob, thiab cov kabmob dov kuj muaj qee qhov tsis zoo, cov tseem ceeb yog:

1. Lub peev xwm thauj khoom ntawm cov kabmob dov yog me dua li ntawm cov kabmob swb ntawm tib lub ntim, yog li ntawd, qhov loj me radial ntawm cov kabmob dov yog loj. Yog li ntawd, thaum muaj kev thauj khoom loj thiab qhov xwm txheej xav tau qhov loj me radial thiab cov qauv me me (xws li lub cav sib xyaw sab hauv crankshaft bearing), cov kabmob swb feem ntau siv;

2. Kev co thiab suab nrov ntawm cov kabmob dov yog loj, tshwj xeeb tshaj yog nyob rau theem tom qab ntawm kev siv, yog li ntawd, thaum qhov yuav tsum tau ua kom raug siab heev thiab kev co tsis raug tso cai, cov kabmob dov nyuaj rau kom muaj peev xwm, thiab cov nyhuv ntawm cov kabmob swb feem ntau zoo dua;

3. Cov kabmob dov yog qhov rhiab heev rau cov khoom txawv teb chaws xws li cov hlau tawg, thiab thaum cov khoom txawv teb chaws nkag mus rau hauv cov kabmob, lawv yuav tsim cov kev co loj thiab suab nrov tsis tu ncua, uas tseem yuav ua rau puas tsuaj thaum ntxov. Tsis tas li ntawd, cov kabmob dov kuj tseem raug kev puas tsuaj thaum ntxov vim muaj cov hlau. Txawm tias kev puas tsuaj thaum ntxov tsis tshwm sim, muaj kev txwv rau lub neej ntawm cov kabmob dov. Hauv ntej, cov kabmob dov muaj lub neej ua haujlwm luv dua li cov kabmob tiaj tus.

 

Piv nrog rau cov kabmob dov thiab cov kabmob swb, txhua tus muaj nws tus kheej qhov zoo thiab qhov tsis zoo, thiab txhua tus nyob rau hauv ib qho xwm txheej siv tau, yog li ntawd, ob qho tib si tsis tuaj yeem hloov pauv ib leeg, thiab txhua tus txhim kho mus rau hauv ib qho kev taw qhia thiab nthuav nws thaj chaw. Txawm li cas los xij, vim muaj qhov zoo tshaj plaws ntawm cov kabmob dov, muaj qhov nyiam rau cov neeg tuaj lig kom yeej. Tam sim no, cov kabmob dov tau tsim los ua hom kev txhawb nqa tseem ceeb ntawm cov tshuab, thiab siv ntau dua thiab ntau dua.
