Tam sim no, cov kabmob yog cov khoom siv kho tshuab uas yog ib feem ntawm kev txhawb nqa. Cov txheej txheem no yog npaj rau kev txhawb nqa ntxiv ntawm axis, ncej thiab lwm yam qauv, pab kom muaj zog thiab txhim kho txoj hauj lwm ntawm lwm yam qauv hauv qhov chaw. Tsis tas li ntawd, cov kabmob muaj peev xwm muab kev txav mus los, dov thiab kev sib hloov nrog tus nqi qis tshaj plaws, thiab tseem muab kev thauj mus los rau ntau yam qauv. Ib qho kev txhawb nqa uas muaj cov kabmob thrust muaj lub npe tshwj xeeb - lub thrust bearing.

Kev faib tawm suav nrog ntau hom kev yooj yim uas txawv ntawm txoj cai ntawm kev ua:

1. Plain bearing.
2. Rolling bearing.
3. Gas static bearing.
4. Gas dynamic bearing.
5. Cov kabmob yog magnetic.
6. Hydrostatic bearing.
7. Hydrodynamic bearing.

thawj ob hom yog siv dav tshaj plaws, txij li lawv tau siv hauv engineering field.

Cia peb saib ze ze ntawm cov kabmob dov. Kev lig kev cai, nws muaj ntau yam qauv: ob lub nplhaib nrog grooves txiav tawm ntawm lawv, dov cov ntsiab lus uas txav raws cov grooves, ib qho cais (cais cov ntsiab lus dov.thiab ua rau qhov khoob ntawm lawv, thiab tseem coj lawv txoj kev txav mus los).

Qee zaum nws tuaj yeem tsim cov kabmob tsis muaj lub tawb. Xws li cov kabmob dov yog siv nyob rau hauv rooj plaub uas nws tsim nyog los muab lub peev xwm loj. Ib qho tshwj xeeb ntawm hom no yog qhov ntau ntawm cov khoom siv dov siv thiab tus nqi qis ntawm kev txwv ceev.

Cov kabmob dov ua haujlwm feem ntau yog vim muaj kev sib txhuam ntawm kev sib txhuam uas tshwm sim, vim tias qhov seem ntawm lub zog uas tshwm sim tsis tseem ceeb. Cov nyhuv no txo qis kev sib txhuam poob thiab txo qhov hnav ntawm lub tshuab no.

Qhov txawv ntawm kaw thiab qhib bearings. Cov qub tau nruab nrog lub kaus mom tiv thaiv, uas tiv thaiv kom tsis txhob muaj cov roj nplua nyeem thiab nkag mus ntawm lub cev txawv teb chaws, tom kawg, yog tias ua haujlwm tsis zoo, tuaj yeem ua tsis tau sai, vim lawv raug rau tag nrho cov khoom saum toj no.

Qhov tseem ceeb ntawm cov kabmob no suav nrog:

1. Maximum load (ob leeg zoo li qub thiab dynamic).
2. Noise pollution level.
3. chav kawm muaj tseeb.
4. Dimsions ntawm dov bearings.
5. Kev xav tau rau cov roj nplua nyeem.
6. Siv peev txheej.

Ntxiv rau, cov kabmob dov tuaj yeem thauj khoom ntawm cov lus qhia sib txawv, xws li perpendicular mus rau axis (radial) lossis parallel (axial).

Txhua yam tseem ceeb,uas tuaj yeem siv los txiav txim lub hom phiaj ntawm cov txheej txheem no tau sau tseg hauv nws cov cim. Lub cim ntawm dov bearings yog tus qauv raws li GOST txoj cai tam sim no. Lub cim ib txwm muaj ntawm lub ntsiab thiab ib qho ntxiv, txhua tus suav nrog tus lej cim cim. Lub peculiarity ntawm kev nyeem ntawv bearing designations yog tias nws yog nqa tawm ntawm sab xis mus rau sab laug.
