Mafunso Ofunsidwa Kawirikawiri (Mafunso Ofunsidwa Kawirikawiri)

Q1: Kodi kusiyana pakati pa mabearings a standard ndi Electric Motor Quality (EMQ) ndi kotani?

Ma bearing a EMQ amayesedwa kwambiri kuti awone kuchuluka kwa kugwedezeka ndi phokoso kuposa ma grade wamba. Ngakhale kuti ma bearing okhazikika amayang'ana kwambiri kuchuluka kwa katundu, mitundu ya EMQ imakonzedwa makamaka kuti ichepetse kugwedezeka kwa msewu wa raceway ndi kugwedezeka kwa zinthu zozungulira pamwamba, kuonetsetsa kuti ntchito ya chete ikugwira ntchito m'nyumba ndi m'chipatala.

Q2: Kodi malo olowera mkati amakhudza bwanji kuchuluka kwa phokoso la ma bearing a mpira wa deep groove?

Mpata wamkati umatsimikiza malo pakati pa zinthu zozungulira ndi misewu ya mpikisano. Ngati mpata uli wothina kwambiri, kukangana ndi kutentha kumawonjezera phokoso. Ngati umasuka kwambiri, kugwedezeka kumachitika. Kusankha mpata woyenera, monga C3, kumalola kutentha kukula pamene kumasunga ma angles abwino kwambiri kuti pakhale chete.

Q3: Kodi ma bearing a phokoso lochepa a injini angagwiritsidwe ntchito m'malo otentha kwambiri?

Inde, koma amafunikira zitsulo zapadera zokhazikika pa kutentha komanso mafuta opangira kutentha kwambiri. Mafuta wamba osapanga phokoso kwambiri amatha kuchepetsedwa kutentha kwambiri, zomwe zimapangitsa kuti chitsulo chigwirizane ndi chitsulo. Mayankho apadera okhudzana ndi mipira ya ceramic kapena zokutira zapadera amatha kusunga mawonekedwe a phokoso lochepa ngakhale kutentha kwambiri.

Q4: N’chifukwa chiyani mabearing amakhala phokoso nthawi yomweyo mukamayika injini yatsopano?

Phokoso ladzidzidzi nthawi zambiri limachitika chifukwa cha "kupindika" (kupindika kwa msewu wothamanga chifukwa cha mphamvu yosayenera yoyikira) kapena kusakhazikika bwino. Ngati mphamvu ikugwiritsidwa ntchito kudzera mu zinthu zozungulira panthawi yokakamiza, pamwamba pake pamakhala kuwonongeka. Kuonetsetsa kuti shaft ndi housing tolerances zili bwino ndikofunikira kwambiri popewa phokoso.

Q5: Kodi ma bearing otetezedwa kapena otsekedwa ayenera kudzozedwanso kangati kuti phokoso likhale lochepa?

Ma bearing ambiri a mota omwe alibe phokoso lotsika amakhala "opakidwa mafuta moyo wonse," zomwe zikutanthauza kuti amakhala otsekedwa ndipo safuna kudzozedwanso. Kuyesa kudzoza bearing yotsekedwa kungayambitse zinthu zodetsa. Ngati phokoso likuwonjezeka, nthawi zambiri zimasonyeza kuti mafuta asungunuka kapena msewu wa raceway watopa, zomwe zimapangitsa kuti bearing isinthidwe.
