Kev sib txhuam kabmob: Labeling

Tam sim no, cov kabmob no yog hu ua ib tug txhua yam khoom uas yog ib feem ntawm cov nyiaj them yug. Qhov no mechanism yog tsim los qhia txhawb cov axis ntawm tus ncej thiab lwm yam, nws yuav pab ntxiv dag zog thiab kev ruaj ntseg rau txoj hauj lwm ntawm lub tsim ua lwm yam ntsiab nyob rau hauv qhov chaw. Tsis tas li ntawd, cov kabmob tej zaum yuav muab linear zog, dov thiab rotating nrog tus nqi qis tshaj kuj muaj nuj nqis, thiab transmits lub load rau ntau yam yam ntxwv xeem. Muaj ib tug tshwj xeeb lub npe them nyiaj yug, nruab nrog thrust kabmob - ntsawj kabmob.

Classification muaj xws li ob peb theem pib hom uas txawv nyob rau hauv lub hauv paus ntsiab lus ntawm kev txiav txim:

1. Lub zawv zawg kabmob.
2. Bearings.
3. Cov Kabmob gasostatic.
4. Gas-dynamic bearings.
5. Sib Nqus bearings.
6. Hydrostatic kabmob.
7. Hydrodynamic bearings.

Cov feem ntau lug siv ua ntej ob hom raws li lawv yog siv nyob rau hauv lub engineering teb.

Xav txog nyob rau hauv ntau yam lub bearings. Feeb ntau, nws muaj ob peb yam ntxwv hais thiab ob lub ntsej carved nrog grooves, dov lub cev uas txav los ntawm cov launders separator (cais dov lub cev thiab nyob qhov khoob ntawm lawv, thiab xa lawv yuav tsiv mus nyob).

Nyob rau hauv tej rooj plaub, tej zaum los tsim bearings tsis muaj separator. Xws li ib tug ntxuag cov kabmob no yog siv nyob rau hauv tus neeg mob qhov twg nws yog tsim nyog los muab ntau dua Nqa muaj peev xwm. Lub qhov txawv feature ntawm no hom yog siv nyob rau hauv ib tug muaj zog npaum li cas ntawm dov lub cev thiab ib tug me me nqi ntawm cov nyiaj pab ntau tshaj ceev.

Cov kabmob ua hauj lwm feem ntau vim sawv kev sib txhuam rog dov, txij thaum lub lwm yam tshwm sim rog yog insignificant nqi. Cov nyhuv no tso cai rau kom txo kev sib txhuam losses thiab zoo heev thiaj li hnav ntawm lub mechanism.

Paub qhov txawv ntawm kaw thiab qhib bearings. Tus thawj nruab nrog kev tiv thaiv npog uas tiv thaiv to ntawm roj thiab ingress ntawm txawv teb chaws lub cev, lub thib ob ib careless tuav tau sai zom raws li raug rau tag nrho cov saum toj no yam.

Lub ntsiab tsis ntawm no hom bearings muaj xws li:

1. Maximum load (ob zoo li qub thiab dynamic).
2. Cov theem ntawm cov suab nrov pa phem.
3. Raug cov chav kawm ntawv.
4. Lub qhov ntev ntawm dov bearings.
5. Yuav tsum muaj rau lubricants.
6. Resource siv.

Nyob rau hauv tas li ntawd, tus ntxuag kabmob muaj peev xwm muaj kev cuam tshuam load muaj ib tug txawv taw qhia, e.g., perpendicular mus rau lub axis (radial) los yog thaum uas tig mus (axial).

Tag nrho cov ntawm cov loj cov yam ntxwv uas yuav pom nyob rau hauv lub sij hawm ntawm lub mechanism, txo nyob rau hauv nws lub cim. Labeling ntawm dov bearings yog standardized nyob rau hauv raws li cov GOST cai. Cim feeb muaj lub ntsiab thiab sub, txhua tus uas muaj xws li ib tug alphanumeric code. Nyeem feature los kabmob yog hais tias nws yog ua li cas txoj cai.
