Kodi Bearing ndi chiyani?

Ma bearings ndi zinthu zamakina zomwe zimapangidwira kuti zithandizire ma shaft ozungulira, kuchepetsa kugundana, ndi kunyamula katundu. Pochepetsa kukangana pakati pa magawo osuntha, mayendedwe amathandizira kuyenda bwino komanso kothandiza kwambiri, kumapangitsa kuti makina azigwira ntchito komanso kukhala ndi moyo wautali. Ma bearings amapezeka muzinthu zambirimbiri, kuchokera kumainjini zamagalimoto kupita kumakina ogulitsa.

Mawu akuti “kunyamula” amachokera ku verebu lakuti “kunyamula,” kutanthauza chinthu cha makina chimene chimathandiza mbali imodzi kuchirikiza inzake. Maonekedwe ofunikira kwambiri a ma bearings amakhala ndi malo onyamula omwe amapangidwa kapena kuphatikizidwa mu gawo, ndi milingo yolondola mosiyanasiyana pokhudzana ndi mawonekedwe, kukula, makulidwe, ndi kuyika kwa pamwamba.

Ntchito za Bearings:

Chepetsani Kukangana: Ma bearings amachepetsa kukangana pakati pa magawo osuntha, zomwe zimapangitsa kuti makina azikhala ndi moyo wautali komanso wautali.

Katundu Wothandizira: Miyendo imathandizira ma radial (perpendicular to shaft) ndi axial (yofanana ndi shaft) katundu, kuonetsetsa bata.

Limbikitsani Kulondola: Pochepetsa kusewera ndikusunga mayanidwe, mayendedwe amakulitsa kulondola kwa makina.

Bearing Materials :

Chitsulo: Chodziwika kwambiri chifukwa cha mphamvu zake komanso kulimba kwake.

Ceramics: Amagwiritsidwa ntchito pothamanga kwambiri komanso malo okhala ndi kutentha kwambiri.

Pulasitiki: Yoyenera malo opepuka komanso owononga.

Mpikisano Wamkati (Mpikisano Wamkati)

Mpikisano wamkati, womwe nthawi zambiri umatchedwa mphete yamkati, ndi mbali ya chimbalangondo chomwe chimamangiriza ku mtengo wozungulira. Ili ndi poyambira yosalala, yopangidwa bwino ndi makina pomwe zinthu zogudubuza zimayenda. Pamene kubereka kumagwira ntchito, mphete iyi imazungulira pamodzi ndi shaft, ikugwira ntchito zomwe zimagwiritsidwa ntchito panthawi yogwiritsira ntchito.

Mpikisano Wakunja (mphete Yakunja)

Kumbali inayo ndi mpikisano wakunja, womwe umakhala wosasunthika mkati mwa nyumba kapena gawo la makina. Mofanana ndi mpikisano wamkati, ulinso ndi polowera, wotchedwa msewu wothamanga, pamene zinthu zogudubuza zimakhala. Mpikisano wakunja umathandizira kusamutsa katundu kuchokera kuzinthu zozungulira kupita ku zina zonse.

Rolling Elements

Awa ndi mipira, zogudubuza, kapena singano zomwe zimakhala pakati pa mitundu yamkati ndi yakunja. Maonekedwe a zinthu izi zimadalira mtundu wa kubala. Mipira imagwiritsa ntchito mipira yozungulira, pomwe zodzigudubuza zimagwiritsa ntchito masilindala kapena zodzigudubuza. Zinthu izi ndizomwe zimathandizira kuchepetsa kukangana ndikulola kusinthasintha kosalala.

Khola (Wosungira)

Khola ndi gawo lomwe nthawi zambiri limanyalanyazidwa koma lofunika kwambiri pamayendedwe. Zimathandiza kuti zinthu zogudubuza zizikhala motalikana pamene zikuyenda, kuwateteza kuti zisagwirizane komanso kuti zisamayende bwino. Makola amapangidwa kuchokera ku zinthu monga zitsulo kapena pulasitiki, kutengera mtundu wa zonyamula ndi ntchito yake.

Zisindikizo ndi Zishango

Izi ndi zinthu zoteteza. Zisindikizo zimapangidwira kuti zisunge zowononga ngati dothi ndi chinyezi kunja kwa bere, ndikusunga mafuta mkati. Zishango zimagwira ntchito yofanana koma zimalola kuti pakhale kumasuka pang'ono. Zisindikizo nthawi zambiri zimagwiritsidwa ntchito m'malo ovuta, pomwe zishango zimagwiritsidwa ntchito pomwe kuipitsidwa sikudetsa nkhawa.

Kupaka mafuta

Ma bearings amafunikira mafuta kuti azigwira ntchito bwino. Kaya mafuta kapena mafuta, mafuta odzola amachepetsa kukangana pakati pa zigawo zomwe zikuyenda ndipo zimathandiza kupewa kuvala. Zimathandizanso kuziziritsa kunyamula, zomwe zingakhale zofunikira pamapulogalamu othamanga kwambiri.

Msewu

Msewu wothamanga ndi poyambira mumipikisano yamkati ndi kunja komwe zinthu zogubuduza zimasuntha. Pamwambapa amayenera kupangidwa ndendende kuti azitha kuyenda bwino komanso kugawa katundu.
