Ensengeka ya Bearing

Bearing okusinga zigabanyizibwa mu biti bina: bbeeri eziyiringisibwa, bbeeri eza bulijjo, bbeeri ezikwatagana mu nkoona, ne bbeeri z’omupiira ezikwatagana. Bearing eziyiringisibwa zikozesa ebintu ebiyiringisibwa (nga ebizingulula n’emipira egy’ekyuma) okukendeeza ku kusikagana era zisaanira okukozesebwa mu sipiidi ya waggulu-, omugugu omungi-. Okugeza, deep groove ball bearings (ezirina sipiidi etuuka ku 20,000 rpm) zikozesebwa mu mmotoka z’emmotoka, ate tapered roller bearings (nga zirina okweyongera kwa 30% mu busobozi bw’omugugu) zisaanira ebyuma ebizito. Bearings eza bulijjo zikolebwa okuva mu bintu ebitono-friction (nga copper alloys ne polytetrafluoroethylene). Graphite sleeve bearings zigumira ebbugumu-(ebbugumu ly’okukola Less than oba eryenkana 500℃). Bearings ezisiigiddwa amazzi-zituuka ku kusikagana okutono ennyo (friction coefficient < 0.001) nga ziyita mu kukozesa firimu ya woyiro, ekizifuula ezisaanira ebikozesebwa ebituufu. Engular contact bearings zisobola okugumira emigugu gyombi egya radial ne axial (contact angles of 15℃-40℃) era zikozesebwa nnyo mu machine tool spindles. Self-ball bearings ezikwatagana zirina omulimu ogw’okwekwataganya (nga zirina deflection compensation angle ya 2℃-3℃) era zisaanira embeera ezikankana ng’ebyuma ebisima eby’obugagga eby’omu ttaka.
