Chipinda chozungulira cha deep groove chimadziwika kuti ndi chodalirika m'mafakitale, koma mainjiniya amakono nthawi zambiri amafuna zambiri. Kuyambira malo ozizira mpaka pakati pa ng'anjo, kuyambira malo osambiramo mankhwala mpaka malo opanda mpweya, zida ziyenera kugwira ntchito m'malo omwe amakankhira zinthu mpaka malire ake. Izi zikubweretsa funso lofunika kwambiri: kodi chipinda chozungulira cha deep groove chodziwika bwinochi chingapirire zovuta zotere, ndipo chimapangidwa bwanji kuti chichite zimenezo?
Mavuto Osiyanasiyana: Kupitilira Mikhalidwe Yoyenera Yogwirira Ntchito
Malo oopsa kwambiri ali ndi ziwopsezo zapadera pa umphumphu wa bere:
Kutentha Kwambiri:Kutentha kwapansi pa zero kumawonjezera mafuta odzola ndi zinthu zosweka, pomwe kutentha kwambiri kumawononga mafuta odzola, kufewetsa zitsulo, ndikupangitsa kutentha kukula.
Kutupa ndi Mankhwala:Kukhudzidwa ndi madzi, ma acid, ma alkali, kapena zosungunulira zinthu kungayambitse kuwonongeka kwa chitsulo chokhazikika komanso cholimba mofulumira.
Kuipitsidwa: Zinthu zofewa zopukutira (fumbi, mchenga), tinthu toyendetsa mpweya, kapena zinthu zokhala ndi ulusi zimatha kulowa, zomwe zimapangitsa kuti magetsi aziwonongeka mofulumira komanso kuti magetsi aziwonongeka.
Malo Otsukira Mowa Wambiri Kapena Otsukira:Mafuta odzola amatha kuwononga mpweya, zomwe zingawononge chilengedwe, pomwe mafuta wamba sagwira ntchito.
Mayankho a Uinjiniya: Kukonza Zovala Zoyenera
Pofuna kuthana ndi mavutowa, chitsulo cholimba cha deep groove ball bearing chimasinthidwa pogwiritsa ntchito zipangizo zapadera, mankhwala, ndi mapangidwe.
1. Kugonjetsa Kutentha Kwambiri
Mabeya Otentha Kwambiri: Gwiritsani ntchito zitsulo zokhazikika kutentha (monga zitsulo za zida), mafuta opangidwa mwapadera otentha kwambiri (silicone, perfluoropolyether), ndi ma cage opangidwa ndi chitsulo chophimbidwa ndi siliva kapena ma polima otentha kwambiri (polyimide). Izi zimatha kugwira ntchito mosalekeza kutentha kopitilira 350°C.
Mabearings a Cryogenic: Amapangidwira mapampu a gasi osungunuka ndi ntchito zamlengalenga. Amagwiritsa ntchito zinthu zomwe zimasunga kulimba kutentha kochepa kwambiri (monga zitsulo zosapanga dzimbiri), mafuta apadera monga molybdenum disulfide kapena mankhwala ochokera ku PTFE, komanso malo owonekera bwino mkati kuti afotokoze kupsinjika kwakukulu kwa zinthuzo.
2. Kulimbana ndi dzimbiri ndi mankhwala
Ma Bearings a Chitsulo Chosapanga Dzimbiri: Chitetezo chachikulu. Chitsulo chosapanga dzimbiri cha Martensitic 440C chimapereka kukana dzimbiri komanso kulimba. Pa malo amphamvu kwambiri (chakudya, mankhwala, za m'madzi), mipira ya AISI 316 yosapanga dzimbiri kapena ya ceramic (silicon nitride) imagwiritsidwa ntchito.
Zophimba Zapadera ndi Mankhwala: Pamwamba pake pakhoza kuphimbidwa ndi black oxide, zinc-nickel, kapena ma polima opangidwa ngati Xylan® kuti pakhale chotchinga chosagwira ntchito motsutsana ndi zinthu zowononga.
3. Kutseka Kuletsa Kuipitsidwa
M'malo odetsedwa kwambiri kapena onyowa, njira yotsekera ndiyo njira yoyamba yodzitetezera. Izi zimapitirira zisindikizo za rabara wamba.
Mayankho Otsekera Olemera: Zisindikizo zolumikizana ndi milomo itatu, zopangidwa ndi mankhwala osagwira mankhwala monga FKM (Viton®), zimagwiritsidwa ntchito. Pamalo ovuta kwambiri, zisindikizo zosakanikirana ndi makina otsukira mafuta zitha kusankhidwa kuti zipange chotchinga chosalowa.
4. Kugwira Ntchito M'malo Apadera
Mabeya Otsukira ndi Oyeretsa: Gwiritsani ntchito zitsulo zotsukira mpweya ndi mafuta apadera ouma (monga siliva, golide, kapena zokutira za MoS2) kapena zopangidwa kuti zizigwira ntchito popanda mafuta ndi zinthu zadothi kuti mpweya usatuluke.
Ma Bearings Osakhala a Magnetic: Amafunika mu makina a MRI ndi zida zolondola. Izi zimapangidwa kuchokera ku zitsulo zosapanga dzimbiri za austenitic (AISI 304) kapena zoumba, zomwe zimapangitsa kuti maginito asasokonezedwe.
Kuwunikira Kugwiritsa Ntchito: Kumene Ma Bearings Ovuta Kwambiri Amatsimikizira Kufunika Kwawo
Kukonza Chakudya ndi Zakumwa: Ma bearing a 316 achitsulo chosapanga dzimbiri okhala ndi mafuta ovomerezedwa ndi FDA amatha kupirira kusamba kwamphamvu tsiku lililonse ndi zotsukira za caustic.
Kukumba ndi Kugwetsa: Maberiya okhala ndi zisindikizo zolemera kwambiri komanso zokutira za tungsten carbide amakhalabe m'mapampu a matope ndi zotsukira zodzazidwa ndi matope okhwima.
Ma Actuator a Aerospace: Ma bearing opepuka, ogwirizana ndi vacuum amatsimikizira kuti amagwira ntchito bwino pa kutentha kwambiri komanso kuthamanga kwa mpweya pouluka.
Kutsiliza: Kavalo Wogwira Ntchito Wosinthika
Chipinda chozungulira chakuya chimatsimikizira kuti kapangidwe kabwino kwambiri kangathe kusinthidwa kuti kakhale kopambana kulikonse. Mwa kusankha mwanzeru zipangizo, mafuta odzola, zosindikizira, ndi mankhwala otentha, mainjiniya amatha kusankha chipinda chozungulira chakuya chomwe sichilinso chinthu wamba, koma njira yopangidwira mwapadera kuti chipulumuke. Kusinthasintha kumeneku kumatsimikizira kuti ngakhale m'mikhalidwe yovuta kwambiri padziko lapansi, mfundo za kuzungulira kosalala komanso kodalirika zitha kupitilira. Kutchula chipinda chozungulira cholondola kwambiri si ndalama zowonjezera—ndi ndalama zogulira nthawi yogwira ntchito komanso kupambana kwa ntchito.
