Ma Bearings a Pulasitiki a Uinjiniya vs. Ma Bearings a Metal Composite

 

Zomwe zikugwiritsidwa ntchito panomaberiyaKawirikawiri zingagawidwe m'magulu ozungulira ndi otsetsereka. Mfundo zogwirira ntchito za ma rolling bearings ndi ma sliding bearings zitha kusiyanitsidwa ndi mayina awo. Ma rolling bearings amakumana ndi kugwedezeka kozungulira, pomwe ma sliding bearings amakumana ndi kugwedezeka kozungulira. Kukula kwa kugwedezeka kozungulira kumadalira makamaka kulondola kwa kupanga.

 

Kukula kwa kukangana kwa ma bearing otsetsereka kumadalira makamaka zinthu zomwe zili pamalo otsetsereka a bearing. Ma bearing otsetsereka nthawi zambiri amakhala ndi malo ogwirira ntchito odzipaka okha mafuta.

 

Ma bearing otsetsereka amagawidwanso m'magulu awiri malinga ndi zinthu zomwe zili m'magulu awiri: ma bearing otsetsereka osakhala achitsulo ndi ma bearing otsetsereka achitsulo.

 

Ma bearing osatsetsereka achitsulo pakadali pano amapangidwa makamaka ndi pulasitiki, yomwe nthawi zambiri imapangidwa ndi pulasitiki yaukadaulo yogwira ntchito bwino.

 

Ma bearing otsetsereka achitsulo amagwiritsidwa ntchito kwambiri m'ma bearing ophatikizika a magawo atatu. Ma bearing amenewa nthawi zambiri amagwiritsa ntchito mbale zachitsulo za kaboni ngati maziko, ndi wosanjikiza wa ufa wozungulira wa mkuwa womwe umayikidwa pa mbale yachitsulo pogwiritsa ntchito ukadaulo wothira, kutsatiridwa ndi wosanjikiza wa mafuta a PTFE pafupifupi 0.03mm makulidwe. Saizi yapakati ya ufa wozungulira wa mkuwa makamaka imawonjezera mphamvu yolumikizirana pakati pa mbale yachitsulo ndi PTFE, komanso imaperekanso mphamvu zonyamula katundu ndi mafuta panthawi yogwira ntchito.

 

Mabeya apulasitikiZimasiyana ndi mabearing otsetsereka achitsulo m'njira zotsatirazi:

 

1. Mabeya apulasitikiGwiritsani ntchito zinthu zopaka mafuta mkati mwake, zomwe zimapangitsa kuti ntchito ikhale yayitali; pomwe ma bearing otsetsereka achitsulo ali ndi gawo lopaka mafuta la PTFE lokhala ndi makulidwe a 0.003mm, ndipo nthawi yawo yogwirira ntchito imatha pamene gawo lochepa ili latha.

 

2. Mabeya apulasitikiSizipanga dzimbiri ndipo sizingagwe dzimbiri, pomwe zitsulo zimakhala ndi dzimbiri ndipo sizingagwiritsidwe ntchito mu njira zamankhwala.

 

3. Mabeya apulasitikiNdi zopepuka kuposa zitsulo, zomwe zimapangitsa kuti zikhale zoyenera kwambiri pakupanga zinthu zopepuka zamakono. 4. Ma pulasitiki ndi otsika mtengo kupanga kuposa zitsulo; ma pulasitiki amapangidwa ndi jekeseni, zomwe zimapangitsa kuti zikhale zoyenera kupanga zinthu zambiri.

 

5. Mabeya apulasitikiZimagwira ntchito popanda phokoso ndipo zimakhala ndi ntchito inayake yoyamwa kugwedezeka. Chifukwa cha ubwino wambiri wa mabearing apulasitiki kuposa mabearing otsetsereka achitsulo, kupanga mabearing apulasitiki kukukulirakulira mofulumira, ndipo ntchito zawo zikufalikira nthawi zonse. Kuyambira zida zolimbitsa thupi mpaka zida zamaofesi ndi makampani opanga magalimoto, mabearing apulasitiki amagwiritsidwa ntchito kulikonse. Pakadali pano, pafupifupi galimoto iliyonse pamsewu imagwiritsa ntchito mabearing apulasitiki.
