Mabeya otentha kwambiri

Mabearing Otentha KwambiriMa bearing omwe amapangidwira kuti azigwira ntchito m'malo omwe sali kutentha kwabwinobwino kwa bearing. Ma bearing achizolowezi nthawi zambiri amapangidwa kuti azigwira ntchito kutentha kuyambira -20°C mpaka 120°C, pomwe ma bearing otentha kwambiri amatha kusunga magwiridwe antchito ndi kudalirika m'malo otentha kwambiri, nthawi zambiri 150°C mpaka 350°C. °C kapena kupitirira apo. Ma bearing otentha kwambiri amapangidwa osati poganizira kukana kutentha kokha, komanso poganizira momwe angathanirane ndi kukulira kwa zinthu zomwe zimayambitsidwa ndi kutentha kwambiri, mavuto okhudzana ndi mafuta, ndi mavuto ena okhudzana ndi thermodynamic ndi chemical stability.

 

Ubwino wa ma bearing otentha kwambiri:

Ma bearing otentha kwambiri amatha kugwira ntchito kutentha kwambiri popanda kulephera ndipo amalimbana ndi kutentha.

Ma bearing otentha kwambiri amapangidwa kuti apewe kuwonongeka ndi kusinthika komwe kumachitika chifukwa cha kutentha kwambiri, zomwe zimapangitsa kuti akhale odalirika kuposa ma bearing wamba.

Ma bearing otentha kwambiri nthawi zambiri amapangidwa pogwiritsa ntchito zipangizo zapadera ndi mafuta odzola.

Ma bearing otentha kwambiri amatha kuchepetsa kugwiritsa ntchito mphamvu zonse komanso ndalama zogwirira ntchito za makina.

Kugwiritsa ntchito ma bearing oyenera otentha kwambiri kumachepetsa chiopsezo cha kulephera kwa zida ndikuwonjezera chitetezo cha kupanga.

Kapangidwe ka ma bearing otentha kwambiri ndi kosinthasintha ndipo kamagwiritsidwa ntchito mosiyanasiyana.

 

Mitundu ya ma bearing otentha kwambiri

Ma bearing otentha kwambiri akhoza kugawidwa m'magulu awiri malinga ndi kapangidwe kake ndi kagwiritsidwe ntchito kake: ma bearing okhazikika komanso ma bearing apadera.

 

Ma berea okhazikika

Kawirikawiri imapangidwa ndi chitsulo cha chromium kapena chitsulo chosapanga dzimbiri, chomwe chimakhala ndi mphamvu yabwino yolimbana ndi kutentha kwambiri mkati mwa malire enaake. Mafuta otentha kwambiri nthawi zambiri amagwiritsidwa ntchito popaka mafuta kuti apitirize kugwira ntchito kutentha kwambiri komanso kupewa kukangana ndi kuwonongeka.

 

Ma berea apadera omangira

Zipangizo zamakono monga zadothi, graphite kapena ma polima ogwira ntchito kwambiri, omwe amalimbana bwino ndi kutentha komanso kuphulika, nthawi zambiri amagwiritsidwa ntchito.

 

Kusiyana pakati pa ma bearing otentha kwambiri ndi ma bearing wamba

Kusiyana kwakukulu pakati pa ma bearing otentha kwambiri ndi ma bearing wamba ndi kuthekera kwawo kugwira ntchito kutentha kwambiri popanda kutaya ntchito. Mphamvu imeneyi imachitika makamaka chifukwa cha zipangizo zapadera ndi mapangidwe omwe amagwiritsidwa ntchito mu ma bearing otentha kwambiri. Mwachitsanzo, ma bearing otentha kwambiri angapangidwe ndi zinthu zadothi zosagwirizana ndi kutentha kwambiri, zitsulo zapadera kapena zinthu za polima zogwira ntchito kwambiri zomwe zimatha kupirira kutentha mpaka 1000°C kapena kupitirira apo, pomwe ma bearing wamba nthawi zambiri amapangidwa ndi zinthu monga chitsulo cha carbon kapena chitsulo chosapanga dzimbiri chomwe chimatha kupirira kutentha kwa 1000°C kapena kupitirira apo. Chimatha kupirira kutentha kwa pafupifupi 250°C.

Kuphatikiza apo, ma bearing otentha kwambiri adapangidwa kuti aziganizira kusintha kwa kutentha, kukhazikika kwa mankhwala ndi mphamvu ya makina pa kutentha kwambiri, kotero mapangidwe apadera amkati ndi machitidwe opaka mafuta nthawi zambiri amagwiritsidwa ntchito kuti agwirizane ndi zovuta zomwe zimayambitsidwa ndi kutentha kwambiri.
