Kusiyanitsa pakati pa ma bearing odzipaka okha ndi ma bearing odzazidwa ndi mafuta

 

Kodi ndi chiyanimafuta odzazidwachogwirira?

Thupi lopangidwa ndi ufa wa metallurgy ndi lodzaza ndi mabowo ndipo lili ndi ubwino waukadaulo wosintha kuchuluka, kukula, mawonekedwe ndi kufalikira kwa mabowo momasuka popanga. Pogwiritsa ntchito ma porosity a thupi lodzaza, limadzazidwa ndi 10%-40% (voliyumu fraction) ya mafuta odzola, ndipo limagwiritsidwa ntchito ngati mafuta odzipangira okha. Pakugwira ntchito, kutentha kwa bearing kumakwera, ndipo popeza coefficient of expansion of oil is greater kuposa chitsulo, limalowa lokha pamwamba kuti lidzoze bearing. Ma bearing odzazidwa ndi mafuta amatha kugwiritsidwa ntchito kwa nthawi yayitali ndi mafuta amodzi, ndipo nthawi zambiri amagwiritsidwa ntchito nthawi zina pomwe kudzaza mafuta kumakhala kovuta.

 

Kodi ndi chiyanikudzipaka mafuta okhachogwirira?

Mabearing odzipaka okhaAmagawidwa m'magulu a mabearing odzipaka okha, ma bearing shaft odzipaka okha olimba, ma bearing odzipaka okha a bimetallic, ndi ma bearing apadera odzipaka okha.

 

Chimodzi mwa mitundu ikuluikulu ya ma bearing olimba odzipangira okha mafuta (omwe amatchedwa JDB) ndi bearing yatsopano yodzozedwa yokhala ndi mawonekedwe a bearing yachitsulo komanso bearing yopanda mafuta, yomwe imadzazidwa ndi matrix yachitsulo ndikudzozedwa ndi zinthu zodzoladzola zolimba zopangidwa mwapadera.

 

Ili ndi makhalidwe monga mphamvu yonyamula katundu wambiri, kukana kukhudza, kukana kutentha kwambiri, mphamvu yodzipaka mafuta kwambiri, ndi zina zotero, makamaka yoyenera kunyamula katundu wolemera, liwiro lotsika, kubwezera kapena kugwedezeka ndi zina zomwe zimakhala zovuta kudzola mafuta ndikupanga filimu yamafuta, ndipo siziopa kuwonongeka kwa madzi ndi kuwonongeka kwa ma asidi ena. Zogulitsazi zagwiritsidwa ntchito kwambiri mumakina oponyera zitsulo opitilira, zida zozungulira, makina opangira migodi, nkhungu, makina okweza, makina opangira nsalu, kupanga mphamvu zamphepo, zombo, ma turbine a nthunzi, ma turbine amadzi, makina opangira jekeseni ndi mizere yopanga zida. Kukana kutopa kuli kawiri kuposa kwa ma bushing wamba.

 

Kusiyana pakati pama bearing odzazidwa ndi mafuta ndi ma bearing odzipaka okha

 

1. Bearing yodzazidwa ndi mafuta imapangidwa ndi ufa wachitsulo wophatikizidwa, wokhala ndi malo ozungulira a 10-40%; Matrix yodzipangira mafuta yokha yolumikizidwa ndi centrifugal casting; Kuchuluka kwa substrate ndi kwakukulu, mphamvu yolumikizira ndi yayikulu kuposa ya ma bearing odzazidwa ndi mafuta, ndipo nthawi yogwira ntchito ndi yayitali kuposa ya ma bearing odzazidwa ndi mafuta.

 

2. Zipangizo zopaka mafuta zomwe zili mu bearing yodzazidwa ndi mafuta ndi mafuta opaka mafuta, ndipo filimu ya mafuta ili ndi makulidwe okwanira kuti athetse kukhudzana mwachindunji pakati pa malo awiri okangana. Pakadali pano, pali kukangana pakati pa mamolekyu amadzimadzi okha, kotero coefficient ya kukangana ndi yaying'ono kwambiri (f = 0.001 ~ 0.008), zomwe zimachepetsa kwambiri kukangana ndi kuwonongeka. Zipangizo zopaka mafuta zomwe zili mu bearing yodzipaka mafuta ndi zinthu zolimba zopaka mafuta, zomwe zimatha kukhala ndi zotsatira zabwino zopaka mafuta ngakhale pansi pa mikhalidwe yopanda mafuta, zomwe zingatsimikizire kuti mafutawo ndi osasinthasintha komanso okhazikika, ndipo moyo wake wogwira ntchito wopaka mafuta umagwirizana ndi moyo wa matrix;

 

Mafuta opaka mu bearing yodzazidwa ndi mafuta ndi osasunthika komanso osavuta kutaya, ndipo kutayika kwa filimu yamafuta opaka kumawonjezeka kutentha kwambiri komanso kuthamanga kwambiri, ndipo zotsatira zoyenera zopaka sizingapezeke; Mu graphite copper sleeve, mafuta olimba amasamutsidwa kapena kusinthidwa kupita pamwamba pa friction kudzera mu friction, ndipo mafuta olimba omwe ali mu dzenje kapena groove amasamutsidwa kapena kusinthidwa kuti apange filimu yolimba yosamutsa yokhala ndi mafuta abwino, yolimba komanso yofanana pamwamba pa friction, zomwe zimachepetsa kwambiri friction ndi closure. Pamene friction ikupita patsogolo, mafuta olimba omwe amaphatikizidwa amaperekedwa nthawi zonse pamwamba pa friction, kuonetsetsa kuti friction pair ikugwira ntchito kwa nthawi yayitali.
