Themayendedwendi zigawo zofunika mu makina makina. Ntchito yake yayikulu ndikuthandizira kusinthasintha kwamakina kuti muchepetse kugunda kwamagetsi kwa zida. Nkhaniyi imagawana mawonekedwe, kusiyanitsa ndi kugwiritsa ntchito kofananira kwamitundu ingapo.
I. Self-Aligning Ball Bearing
Mizere iwiri yazitsulo zachitsulo, chogudubuza chakunja ndi chozungulira chamkati, kotero chimatha kusintha tsinde kapena chipolopolo kapena mtima wina wolakwika, kunyamula dzenje la cone kumatha kukhazikitsidwa mosavuta pa shaft pogwiritsa ntchito zomangira, makamaka zonyamula ma radial load. Kugwiritsa ntchito kwakukulu: makina opangira matabwa, makina opangira nsalu amayendetsa shaft, mipando yowongoka yokhala ndi pakati.

II.Mpira wakuya wa groove
Chipinda chilichonse cha mpira wa structural deep groove mpira chimakhala ndi chogudubuza chopitirira pafupifupi gawo limodzi mwa magawo atatu a mpirawo. Mipira yakuya ya groove imagwiritsidwa ntchito makamaka kupirira katundu wa radial ndipo imatha kupirira katundu wina wa axial. Pamene kunyamula ma radial kuyenda kusiyana ukuwonjezeka, angular kukhudzana mpira kubala, akhoza kupirira axial katundu alternating mbali ziwiri. Poyerekeza ndi mitundu ina ya mayendedwe a kukula kofanana, mayendedwe oterowo ali ndi kagawo kakang'ono kakukangana, liwiro laling'ono komanso kulondola kwambiri, komwe ndi mtundu womwe umasankhidwa kuti usankhe ogwiritsa ntchito. Ntchito zazikulu: galimoto, thirakitala, zida zamakina, mota, mpope wamadzi, makina aulimi, makina opangira nsalu, etc.
Ndipo chomaliza ndi Mfundo Zinayi zikukhudzana ndi mayendedwe a mpira
Imatha kupirira ma radial ndi bidirectional axial katundu, chonyamula chimodzi chikhoza kukhala m'malo mwa axial axial katundu wonyamula ndikulumikizana kutsogolo kapena kuphatikiza kumbuyo, komwe kumagwiritsidwa ntchito kupirira katundu wambiri wa axial axial pansi pa katundu wa axial mbali iliyonse, kotero mphete zimalumikizana ndi mpira pamzere uliwonse wolumikizana.
Malingaliro aliwonse okhudzana ndi kubereka angatumizidwe kwa ife!
