Kuyerekeza kwa mabearing ozungulira ndi mabearing osavuta

Kugwiritsa ntchitomaberiya, Kapangidwe ka kukangana kwa ma bearing mounting bearing kangagawidwe m'ma rolling bearing ndi sliding bearing, titha kusankha mitundu yosiyanasiyana ya ma bearing malinga ndi zofunikira pakugwiritsa ntchito, ma rolling bearing ndi sliding bearing ali ndi makhalidwe osiyanasiyana ogwiritsira ntchito,

Zinthu zazikulu zamabearing ozungulirandi:

1. Kuchepetsa kupsinjika pang'ono (poyerekeza ndi bere loyenda losakhala lamadzimadzi), kuyambitsa kosinthika;

2. Imatha kunyamula katundu wozungulira ndi wozungulira nthawi imodzi, zomwe zimapangitsa kuti kapangidwe kothandizira kakhale kosavuta;

3. Kutuluka kwa radial ndi kochepa, ndipo kutulukako kumatha kuchotsedwanso pogwiritsa ntchito njira yoyika kale, kotero kulondola kwa kuzungulira kumakhala kwakukulu;

4. Kusinthasintha kwabwino komanso kukonza kosavuta.

 

Zinthu zazikulu zamabenchi wambandi:

1. Ntchito yokhazikika komanso yopanda phokoso;

2. Kulondola kwambiri kwa kuzungulira;

3. Kutayika pang'ono kwa kukangana panthawi ya mafuta amadzimadzi;

4. Kukula kochepa kwa radial;

5. Mphamvu yonyamula katundu wambiri.

 

Kodi ubwino ndi kuipa kwa ma bearing ozungulira ndi kotani poyerekeza ndi ma bearing osavuta? Kusanthula kuli motere:

 

Poyerekeza ndi mabearing wamba, mabearing ozungulira ali ndi ubwino wotsatira:

1. Chiŵerengero cha kugwedezeka kwa mabearing ozungulira ndi chochepa kuposa cha mabearing otsetsereka, ndipo mphamvu ya kutumiza ndi yayikulu. Kawirikawiri, chiŵerengero cha kugwedezeka kwa mabearing otsetsereka ndi 0.08-0.12, pomwe chiŵerengero cha kugwedezeka kwa mabearing ozungulira ndi 0.001-0.005 yokha;

2. Ma bereki ozungulira akhala ofanana, osinthidwa ndi ophatikizidwa, oyenera kupanga zinthu zambiri komanso kupereka, ndipo ndi osavuta kugwiritsa ntchito ndi kusamalira;

3. Maberiyani ozungulira amapangidwa ndi chitsulo cholumikizira ndipo amatenthedwa, kotero maberiyani ozungulira samangokhala ndi mphamvu zambiri zamakanika komanso moyo wautali, komanso amatha kusunga zitsulo zodula zopanda chitsulo zomwe zimagwiritsidwa ntchito popanga maberiyani otsetsereka;

4. Kutseguka kwa mkati mwa chogwirira chozungulira ndi kochepa kwambiri, ndipo kulondola kwa makina a gawo lililonse ndi kwakukulu, kotero kulondola kwa kuthamanga ndi kwakukulu. Nthawi yomweyo, kulimba kwa chogwirira kumatha kuwonjezeka poyika pasadakhale. Izi ndizofunikira kwambiri pamakina olondola;

5. Mabearing ena ozungulira amatha kunyamula katundu wozungulira ndi katundu wa axial nthawi imodzi, kotero kapangidwe ka bearing bearing kakhoza kukhala kosavuta;

6. Chifukwa cha mphamvu yotumizira magiya ambiri komanso kutentha kochepa kwa magiya ozungulira, kugwiritsa ntchito mafuta odzola kumatha kuchepetsedwa, ndipo mafuta odzola ndi kukonza zimakhala zosavuta;

7. Ma rolling bearing angagwiritsidwe ntchito mosavuta ku uranium mbali iliyonse ya mlengalenga.

 

 

Komabe, chilichonse chimagawidwa m'magulu awiri, ndipo ma bereji ogudubuza alinso ndi zovuta zina, zazikulu ndi izi:

1. Mphamvu yonyamula katundu ya ma rolling bearing ndi yochepa kwambiri kuposa ya ma sliding bearing a voliyumu yomweyo, motero, kukula kwa ma rolling bearing ndi kwakukulu. Chifukwa chake, pakakhala katundu wambiri komanso pakakhala kufunika kukula kochepa kwa ma radial ndi kapangidwe kakang'ono (monga crankshaft bearing ya injini yamkati), ma sliding bearing amagwiritsidwa ntchito kwambiri;

2. Kugwedezeka ndi phokoso la ma bearing ozungulira ndi lalikulu, makamaka pakapita nthawi yogwiritsidwa ntchito, chifukwa chake, pamene zofunikira zolondola zili zapamwamba kwambiri ndipo kugwedezeka sikuloledwa, ma bearing ozungulira ndi ovuta kukhala oyenerera, ndipo zotsatira za ma bearing otsetsereka nthawi zambiri zimakhala bwino;

3. Ma rolling bearing ndi ofunikira kwambiri ku zinthu zakunja monga zitsulo, ndipo zinthu zakunja zikangolowa mu bearing, zimapanga kugwedezeka kwakukulu ndi phokoso, zomwe zimayambitsanso kuwonongeka koyambirira. Kuphatikiza apo, ma rolling bearing nawonso amatha kuwonongeka koyambirira chifukwa cha zitsulo zomwe zimayikidwamo. Ngakhale kuwonongeka koyambirira sikuchitika, pali malire a moyo wa ma rolling bearing. Mwachidule, ma rolling bearing amakhala ndi nthawi yochepa yogwirira ntchito kuposa ma plain bearing.

 

Poyerekeza ndi ma bearing ozungulira ndi ma bearing otsetsereka, chilichonse chili ndi zabwino ndi zoyipa zake, ndipo chilichonse chimakhala ndi nthawi yake yoyenera, motero, ziwirizi sizingalowe m'malo mwake, ndipo chilichonse chimakula mbali ina ndikukulitsa munda wake. Komabe, chifukwa cha zabwino zazikulu za ma bearing ozungulira, pali chizolowezi choti ochedwa azipambana. Pakadali pano, ma bearing ozungulira apangidwa kukhala makina othandizira kwambiri, ndipo amagwiritsidwa ntchito kwambiri.
