Kev sib piv ntawm dov bearings thiab dawb bearings

Rau kev sivbearings, cov khoom sib txhuam ntawm cov kabmob mounting tuaj yeem muab faib ua cov kabmob dov thiab cov kabmob zawv zawg, peb tuaj yeem xaiv cov kabmob sib txawv raws li cov kev xav tau tshwj xeeb ntawm kev siv, dov bearings thiab zawv zawg bearings muaj cov yam ntxwv sib txawv ntawm kev siv,

Lub ntsiab nta ntawmdov bearingsyog:

1. Kev sib txhuam me me damping (xws li kev sib txhuam tsis muaj kua nplaum zawv zawg), hloov tau yooj yim pib;

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

3. Lub radial clearance yog me me, thiab qhov clearance kuj yuav raug tshem tawm los ntawm txoj kev preloading, yog li qhov kev sib hloov raug siab;

4. Kev sib hloov tau zoo thiab kev saib xyuas yooj yim.

 

Lub ntsiab nta ntawmdawb bearingsyog:

1. Kev ua haujlwm ruaj khov thiab tsis muaj suab nrov;

2. Kev sib hloov siab raug;

3. Kev sib txhuam me me thaum lub sij hawm ua kua lubrication;

4. me me radial loj;

5. Cov kabmob muaj peev xwm.

 

Dab tsi yog qhov zoo thiab qhov tsis zoo ntawm dov bearings piv nrog cov kabmob dawb? Analysis yog raws li nram no:

 

Piv nrog cov kabmob dawb, dov bearings muaj qhov zoo hauv qab no:

1. Kev sib txhuam coefficient ntawm dov bearings yog me dua li cov zawv zawg bearings, thiab kev sib kis tau zoo. Feem ntau, kev sib txhuam coefficient ntawm zawv zawg bearings yog 0.08-0.12, thaum kev sib txhuam coefficient ntawm dov bearings tsuas yog 0.001-0.005;

2. Rolling bearings tau standardized, serialized thiab generalized, haum rau loj ntau lawm thiab muab, thiab yog heev yooj yim mus use thiab tswj;

3. Rolling bearings yog ua los ntawm cov kabmob steel thiab raug kev kho cua sov, yog li dov bearings tsis tsuas yog muaj cov cuab yeej siv siab thiab kev pab lub neej ntev, tab sis kuj tuaj yeem txuag tau cov khoom kim heev uas tsis yog-ferrous hlau siv hauv kev tsim cov zawv zawg bearings;

4. Lub hauv paus clearance ntawm dov bearing yog heev me me, thiab lub machining raug ntawm txhua qhov yog siab, yog li cov neeg khiav hauj lwm yog siab. Nyob rau tib lub sijhawm, rigidity ntawm cov kabmob tuaj yeem nce ntxiv los ntawm kev thauj khoom ua ntej. Qhov no tseem ceeb heev rau precision machinery;

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

6. Vim muaj kev sib kis tau zoo thiab tsis tshua muaj hluav taws kub ntawm cov kabmob dov, kev noj cov roj lubricating tuaj yeem txo, thiab lubrication thiab tu yooj yim dua;

7. Rolling bearings tuaj yeem siv tau yooj yim rau uranium hauv txhua qhov kev taw qhia ntawm qhov chaw.

 

 

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

1. Lub peev xwm ntawm lub peev xwm ntawm dov bearings yog ntau me dua li cov zawv zawg bearings ntawm tib lub ntim, yog li ntawd, lub radial loj ntawm dov bearings yog loj. Yog li ntawd, nyob rau hauv lub sij hawm ntawm bearing loj load thiab lub sij hawm yuav tsum tau me me radial loj thiab compact qauv (xws li internal combustion engine crankshaft bearing), zawv zawg bearings feem ntau yog siv;

2. Lub vibration thiab suab nrov ntawm dov bearings yog loj, tshwj xeeb tshaj yog nyob rau hauv lub tom ntej no theem ntawm kev siv, yog li ntawd, thaum lub precision yuav tsum tau siab heev thiab kev co tsis tso cai, dov bearings yog ib qho nyuaj rau muaj peev xwm, thiab cov nyhuv ntawm zawv zawg bearings yog. feem ntau zoo dua;

3. Rolling bearings yog tshwj xeeb tshaj yog rhiab heev rau txawv teb chaws lub cev xws li hlau chips, thiab ib zaug cov khoom txawv teb chaws nkag mus rau hauv cov kabmob, lawv yuav tsim kev vibration loj thiab suab nrov, uas yuav ua rau muaj kev puas tsuaj thaum ntxov. Tsis tas li ntawd, dov bearings kuj raug rau kev puas tsuaj thaum ntxov vim cov hlau suav nrog. Txawm hais tias kev puas tsuaj thaum ntxov tsis tshwm sim, muaj kev txwv rau lub neej ntawm dov bearings. Hauv luv luv, dov bearings muaj lub neej ua haujlwm luv dua li cov kabmob dawb.

 

Piv nrog rau dov bearings thiab zawv zawg bearings, txhua tus muaj nws tus kheej qhov zoo thiab qhov tsis zoo, thiab txhua tus nyob hauv qee lub sijhawm, yog li ntawd, ob qho tib si tsis tuaj yeem hloov pauv tag nrho, thiab txhua tus txhim kho nyob rau hauv ib qho kev taw qhia thiab nthuav nws lub teb. Txawm li cas los xij, vim qhov zoo tshaj plaws ntawm dov bearings, muaj kev nyiam rau latecomers kom yeej. Tam sim no, dov bearings tau tsim rau hauv hom kev txhawb nqa tseem ceeb ntawm cov tshuab, thiab siv ntau thiab ntau dua.
