Mabearing oyenera malo otentha kwambiri, otentha pang'ono komanso oipitsidwa!

Mabearing ndi chimodzi mwa zinthu zofunika kwambiri pa zinthu zamagalimoto. Mikhalidwe yapadera yogwirira ntchito imapangitsa kuti mabearing okha ndi mafuta awo azifunika kwambiri. Mwachitsanzo, malo otentha kwambiri, malo otentha pang'ono, kusinthasintha kwakukulu kwa kutentha, ndi malo okhala ndi zinthu zoipitsa mpweya zonse zimakhala ndi mikhalidwe yapadera yomwe imafuna kusankha mosamala mabearing. Opanga ena a mabearing apanga mabearing apadera oyenerera mikhalidwe imeneyi. Ichi ndi chidziwitso chofunikira chomwe opanga magalimoto ayenera kumvetsetsa ndikudziwa bwino kuti apewe kusadalirika kwa magalimoto chifukwa cha kusankha kosayenera kwa mabearing.

Ma bearing a mpira wozama kwambiri oyenera kutentha kwambiri komanso kotsika amapangidwa mofanana ndi ma bearing a mpira wozama kwambiri. Ma bearing awa ali ndi kapangidwe kake kokhala ndi mpata wokweza mpira, wokhoza kupirira katundu wozungulira wa radial ndi katundu wa axial mbali zonse ziwiri. Ali ndi malo otseguka mkati ndipo ali ndi ma cage apadera. Malo otseguka a ma bearing a mpira wozama kwambiri kutentha kwambiri ndi owirikiza kanayi kuposa C5 clearance, zomwe zimaletsa ma bearing kuti asamamatire panthawi yozizira mwachangu. Malo ophimba ma bearing ndi fumbi amachiritsidwa ndi manganese phosphating kuti apewe dzimbiri ndikuwongolera magwiridwe antchito. Pa ma bearing a kutentha kwambiri komanso otsika okhala ndi ma cage achitsulo osindikizidwa komanso opanda zisindikizo, chisakanizo cha polydiol ndi graphite chimagwiritsidwa ntchito ngati mafuta, ndipo amatha kugwira ntchito mkati mwa kutentha kwa -40°C mpaka 250°C. Komabe, akagwiritsidwa ntchito m'malo otentha kwambiri opitilira 200°C, mafuta olimba ayenera kusankhidwa.

Maberiyani otentha kwambiri okhala ndi zophimba zafumbi mbali zonse ziwiri amatha kuletsa zodetsa zina zolimba kuti zisalowe. Maberiyani awa amadzazidwa kale ndi mafuta owirikiza kawiri kuposa maberiyani wamba, koma sali oyenera kugwiritsidwa ntchito osazungulira. Pa maberiyani omwe amagwiritsidwa ntchito kutentha kwambiri, mabuloko a graphite ogawidwa amagwiritsidwa ntchito ngati zosungira khola. Kutentha kogwira ntchito ndi kuyambira -150°C mpaka +350°C. Mabuloko a graphite ogawidwa awa amalekanitsa mipira ndikugwira ntchito ngati khola wamba, komanso amagwira ntchito ngati mafuta. Fumbi lomwe limaphimba mbali zonse ziwiri za maberiyani limatha kutsogolera mabuloko a graphite mkati ndikuletsa zodetsa zolimba kulowa. Maberiyani akamazungulira, ufa wochepa wa graphite kuchokera ku mabuloko a graphite umagwa kuti ulowetse m'misewu ya raceways ndi mipira ya maberiyani. Ubwino wina wa kapangidwe kameneka ndikuti sungakhudze chilengedwe, chifukwa palibe mpweya woipa kapena nthunzi zomwe zimatuluka ngakhale kutentha kwambiri.

Bearing iyi, yoyenera kutentha kwambiri komanso liwiro lozungulira kwambiri, ndi chinthu chapamwamba kwambiri mu mndandanda wa bearing wotentha kwambiri. Ili ndi khola lopangidwa mwapadera la graphite lopangidwa mwapadera, lomwe limathetsa zopinga zambiri zomwe zimakumana nazo pakugwiritsa ntchito kutentha kwambiri.
