Kodi mungakonze bwanji makonzedwe oyenera a ma mota pogwiritsa ntchito ma bearing a mpira olumikizana ndi angular?

Pa ma mota oyima pomwe mphamvu ya axial ilipo moyenera, ambirimabearing a mpira wolumikizana ndi angularamagwiritsidwa ntchito, ndiko kuti, mphamvu yonyamula katundu wa axial ya thupi lonyamula katundu imagwiritsidwa ntchito kulinganiza mphamvu yotsika ya axial yopangidwa ndi kulemera kwa rotor ya mota yoyimirira.

Mu kapangidwe ka kapangidwe ka makina operekera ma mota, ma bearing a mpira wolumikizana ndi angular nthawi zambiri amasewera gawo lolinganiza mphamvu za axial ndi ma bearing positioning nthawi imodzi; kaya ma bearing a mpira wolumikizana ndi angular ayikidwa pamwamba kapena pansi, ma bearing akulinganiza axis yotsika yopangidwa ndi kulemera kwa rotor. Mphamvu, ndiko kuti, pamene bearing ya mpira wolumikizana ndi angular yayikidwa kumapeto kwa injini, bearing imakhala ndi mphamvu yokweza pamwamba pa rotor; ndipo pamene bearing yayikidwa kumapeto kwa injini, bearing imakhala ndi mphamvu yokoka pa rotor. Chifukwa chake, pa ma mota oyima, nthawi zambiri amagwiritsidwa ntchito ma bearing a mpira wolumikizana ndi mzere umodzi.

Kuchokera ku kusanthula kwa chiphunzitso, ma bearing a mzere umodzi amatha kupirira katundu wa radial ndi katundu wa axial wa njira imodzi. Ma angles olumikizana amtunduwu wa ma bearing ndi 15°, 25° ndi 40°. Ngodya yolumikizana ikakhala yayikulu, mphamvu yolimbana ndi katundu wa axial imakhala yayikulu. Komabe, ngodya yolumikizana ikakhala yaying'ono, imakhala yabwino kwambiri kuzungulira mwachangu. Chifukwa chake, posankha ngodya yolumikizirana ya bearing, liwiro la mota liyenera kuganiziridwa mokwanira.

Maberiyani a mpira wolumikizana ndi mizere iwiri amagawidwa m'magulu awiri: mphete imodzi yakunja ndi mphete ziwiri zamkati, ndi mphete imodzi yakunja ndi mphete imodzi yamkati. Mwa kapangidwe kake, maberiyani awiri a mpira wolumikizana ndi mzere umodzi amaphatikizidwa kumbuyo kuti agawane mphete yamkati ndi mphete yakunja, yomwe imatha kunyamula katundu wozungulira komanso katundu wa axial wa bidirectional. Mtundu uwu wa maberiyani umagwiritsidwa ntchito makamaka mu ma spindles a zida zamakina, ma mota okwera kwambiri, ma turbine a gasi, mapampu amafuta, ma compressor a mpweya, makina osindikizira, ndi zina zotero.

Mu ntchito zenizeni, kuphatikiza kwa kumbuyo ndi kumbuyo (DB) ndi kuphatikiza kwa nkhope ndi nkhope (DF) kwa ma bearing a angular contact a mzere umodzi, komanso ma bearing a mzere umodzi, amatha kunyamula katundu wa radial ndi katundu wa bidirectional axial. Kuphatikiza kwa single row angular contact bearing (DT) komwe kumakonzedwa motsatizana ndi koyenera kokha pa ntchito pomwe katundu wa one-way axial ndi waukulu ndipo katundu wovotera wa single bearing siwokwanira.

Mu mikhalidwe yeniyeni yogwiritsira ntchito mota, kuwonjezera pa mphamvu ya axial panthawi yogwira ntchito ya mota, ngati kusakhazikika bwino kwa shaft center komwe kumachitika chifukwa cha zinthu zopatuka monga shaft kapena housing kuyeneranso kuganiziridwa, ma bearing ozungulira angagwiritsidwenso ntchito.
