Mipira imagawika m'magulu atatu: mayendedwe a mpira wakuya, mayendedwe a mpira wolumikizana, ndi mayendedwe a mpira.
Mipira yonyamula ndi mtundu wamba womwe umagwiritsidwa ntchito pazida zamakina ndipo amagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana. Kutengera kapangidwe kawo ndi kagwiritsidwe ntchito kake, mayendedwe a mpira amagawidwa m'magulu awa:
1. Deep Groove Ball Bearings
Deep groove Ball bearings ndi choyimira chozungulira chokhala ndi ntchito zosiyanasiyana. Iwo makamaka amathandizira katundu wa radial, koma amatha kupirira katundu wina wa axial. Pamene chiwongolero cha ma radial chiwonjezeke chikuwonjezeka, amawonetsa magwiridwe antchito a mipira yolumikizana ndipo amatha kupirira katundu wokulirapo wa axial. Kuphatikiza apo, ma faniwa ali ndi mulingo wina wodziyendera okha ndipo amatha kugwirabe ntchito moyenera akapendekeka 2' mpaka 10' pokhudzana ndi bore lanyumba, ngakhale izi zimakhala ndi mphamvu yobereka. Mpira wakuya wa groove nthawi zambiri umakhala ndi zitsulo zokhala ndi malata, pomwe zokulirapo nthawi zambiri zimagwiritsa ntchito makola olimba achitsulo.
2. Angular Contact Ball Bearings
Mipira yolumikizana ndi angular imatha kuthandizira ma radial ndi axial katundu, kapena katundu wa axial. Amakhala ndi liwiro lalitali kwambiri ndipo amatha kuthandizira ma radial ndi axial katundu, komanso katundu wa axial woyera. Kuchuluka kwawo kwa axial kumatsimikiziridwa ndi ngodya yolumikizirana ndikuwonjezeka ndikuwonjezera kukhudzana. Single-mizere yamakona amipira yolumikizana imatha kunyamula ma axial mbali imodzi. Pothandizira zonyamula ma radial, mphamvu zowonjezera za axial zimapangidwa, zomwe zimafunikira kuti zigwiritsidwe ntchito motsatana. Chifukwa chake, ma bere awa nthawi zambiri amagwiritsidwa ntchito pawiri. Pawiri-mizere yolumikizana ndi mipiringidzo yolumikizana imatha kupirira ma radial ndi ma axial ophatikizika ndi katundu wocheperako, makamaka ma radial load. Amatha kuchepetsa kusuntha kwa axial kwa tsinde kapena nyumba ndikukhala ndi mbali yolumikizana ya madigiri 30.
Chachitatu. Kuthamanga Mpira Bearings
Mipira yokhotakhota ndi mayendedwe olekanitsidwa. The shaft washer ndi mpando washer akhoza kupatulidwa ndi khola ndi zitsulo mpira msonkhano, kuwapangitsa kukhala zosavuta kukhazikitsa ndi disassemble. Mipira yothamanga imakhala ndi washer, mipira, ndi khola. Chinthu chothandizira chomwe chimagwirizanitsa ndi shaft chimatchedwa shaft washer, pamene chochapira mipando chimagwirizana ndi nyumba. Mapiritsi a mpira amatha kuthandizira katundu wa axial. Single-ma berelo a mpira amatha kunyamula ma axial polowera mbali imodzi, pomwe -pawiri -ma mayendedwe olowera amatha kunyamula ma axial mbali zonse ziwiri. Sangathe kunyamula katundu wa radial. Mipira yokhotakhota imakhalanso ndi kamangidwe kokhala ndi mpando. Popeza malo okwera pampando ndi ozungulira, kachitidweko kamakhala ndi{10}}kudzimangirira komweko, komwe kungachepetse zovuta za kuyikapo.
