Bearings ndi zigawo zikuluzikulu za makina ndi zipangizo.Mitundu yazinthu zomwe zimagwiritsidwa ntchito popanga ma bearings ndizosiyana.Ma bearings amafotokoza kugwiritsa ntchito zinthu wamba pama bere ozama a groove.Miyendo yakuya ndi mtundu wodziwika kwambiri wa mpira.Mipira yoyambira yakuya imakhala ndi mphete yamkati, mphete yakunja, mpira, khola ndi mafuta.Malingana ndi malo osiyanasiyana ogwiritsira ntchito, tikhoza kugawidwa m'magulu anayi.

Kusanthula kwa zida zinayi zodziwika bwino zama bere ozama a groove

1. Zida za ferrules ndi mipira: Ma Ferrules ndi mipira nthawi zambiri amapangidwa ndi zitsulo zokhala ndi carbon chromium.Mipira yambiri yozama kwambiri imagwiritsa ntchito chitsulo cha SUJ2 mumtundu wazitsulo wa JIS, womwe ndi chitsulo cha chromium chapakhomo (GCr15).Mankhwala a SUJ2 akhala akugwiritsidwa ntchito ngati chotengera chokhazikika m'maiko osiyanasiyana padziko lonse lapansi.Mwachitsanzo, ndi gulu lomwelo lachitsulo monga AISL52100 (USA), DIN100Cr6 (West Germany), ndi BS535A99 (UK).Kuphatikiza pa mitundu yazitsulo yomwe ili pamwambayi, zitsulo zothamanga kwambiri zokhala ndi kutentha kwambiri komanso zosapanga dzimbiri zokhala ndi zowonongeka zowonongeka zimagwiritsidwanso ntchito ngati zopangira zinthu zopangira zinthu malinga ndi ntchito yeniyeni.

2. Zinthu za khola: Zinthu za khola losindikizidwa zimapangidwa ndi chitsulo chochepa cha carbon.Kutengera ndikugwiritsa ntchito, mbale zamkuwa ndi zitsulo zosapanga dzimbiri zitha kugwiritsidwanso ntchito.Zida za khola lachitsulo ndi mkuwa wochuluka kwambiri, chitsulo cha carbon, ndi utomoni wopangira.

3. Chivundikiro cha fumbi ndi mphete yosindikiza: Chophimba cha fumbi chimapangidwa ndi chitsulo cha carbon monga muyezo.Ngati ndi kotheka, AISI-300 zitsulo zosapanga dzimbiri zitha kusankhidwa.Mitundu yosiyanasiyana ya zipangizo zosindikizira zingagwiritsidwe ntchito pa kutentha kwakukulu komanso kugwirizanitsa ndi mafuta.Fluorocarbon, silikoni ndi PTFE zisindikizo zambiri ntchito pa kutentha kwambiri.

4. Mafuta: Ma bearings okhala ndi zisoti zafumbi ndi zosindikizira amadzazidwa ndi mafuta wamba.Mafuta osiyanasiyana angagwiritsidwe ntchito malinga ndi zofunikira zenizeni.Ma bere otsegula amtundu wa deep groove amagwiritsa ntchito mafuta odzola.
