Kusamalira Mavuto Omwe Alipo Pakali pano a Bearing Temperature ndi Shaft mu Coreless Motor Systems

Kutentha kwa mabearing ndi gawo lofunikira pa ntchito yawo. Kawirikawiri, bearing imakhala ndi kutentha kofanana komwe kutentha komwe kumapangidwa kumakhala kofanana ndi kutentha komwe kwatha, motero kusunga kutentha kokhazikika mkati mwa dongosolo la mabearing.

Kutentha kwakukulu kovomerezeka kwa ma bearing a mota kumatsekedwa pa 95°C, poganizira za ubwino wa zinthu ndi mafuta omwe amagwiritsidwa ntchito. Malire awa amatsimikizira kuti dongosolo la bearing limakhalabe lokhazikika popanda kupangitsa kutentha kwakukulu m'ma windings a mota yopanda core.

Magwero akuluakulu a kutentha m'mabearing ndi mafuta osakwanira komanso kutentha kosakwanira. Mwachizolowezi, makina oyeretsera mabearing amatha kulephera chifukwa cha zolakwika zosiyanasiyana pakugwira ntchito kapena kupanga.

Mavuto monga kusakwanira kwa malo operekera ma bearing, kusagwirizana bwino pakati pa bearing ndi shaft kapena housing, kungayambitse kuyenda kosakhazikika; kusokonekera kwakukulu chifukwa cha mphamvu za axial; komanso kusagwirizana bwino ndi zinthu zina zomwe zimasokoneza mafuta, zonsezi zingayambitse kutentha kwambiri kwa ma bearing panthawi yogwira ntchito ya injini. Mafuta amatha kusweka ndikulephera kutentha kwambiri, zomwe zimapangitsa kuti makina operekera ma bearing a injini alephereke mwachangu. Chifukwa chake, kuwongolera molondola momwe zinthu zimagwiritsidwira ntchito komanso momwe zimagwiritsidwira ntchito ndikofunikira kwambiri pakupanga, kupanga, ndi kukonza injini.

Mphamvu ya shaft ndi chiopsezo chosathawika cha ma mota akuluakulu, makamaka ma mota amphamvu komanso osinthasintha. Izi zimakhala zoopsa kwambiri ku ma bearing system a ma mota opanda mphamvu. Popanda kuchepetsa bwino, ma bearing system amatha kuwonongeka mkati mwa masekondi chifukwa cha mphamvu ya shaft, zomwe zimapangitsa kuti iwonongeke mkati mwa maola ochepa. Zizindikiro zoyambirira za vutoli ndi monga kuwonjezeka kwa phokoso la ma bearing ndi kutentha, kutsatiridwa ndi kulephera kwa mafuta, ndipo posakhalitsa, kuwonongeka kwa ma bearing komwe kungayambitse kuti shaft igwire. Pofuna kuthana ndi izi, ma mota amphamvu amphamvu amphamvu amphamvu amphamvu amphamvu, osinthasintha, komanso otsika amagwiritsa ntchito njira zopewera pakupanga, kupanga, kapena kugwira ntchito. Njira zodziwika bwino zimaphatikizapo kusokoneza kwa dera (kugwiritsa ntchito ma bearing otetezedwa, ma insulation end caps, ndi zina zotero) ndi kusintha kwa mphamvu (kugwiritsa ntchito maburashi a carbon okhazikika kuti ayendetse mphamvu kutali ndi makina oyendetsera magetsi).
