Kutentha ndi chinthu chosapeŵeka panthawi yogwira ntchito. Muzochitika zodziwika bwino, kutentha ndi kutentha kwa chimbalangondo kudzafika pamtunda wofanana, ndiko kuti, kutentha komwe kumatulutsa ndi kutentha komwe kumatulutsa kumakhala kofanana, kotero kuti dongosolo lonyamula katundu likhalebe kutentha kokhazikika. boma.
Kutengera kukhazikika kwazinthu zonyamulira zokha komanso mafuta omwe amagwiritsidwa ntchito, kutentha kwazinthu zamagalimoto kumayendetsedwa pa 95 ° C ngati malire apamwamba. Ngakhale kuonetsetsa kukhazikika kwa dongosolo lonyamula katundu, sikudzakhala ndi zotsatira zazikulu pakukwera kwa kutentha kwamotere wopanda mazikozokhotakhota.
Zomwe zimayambitsa kutentha m'machitidwe obereka ndizopaka mafuta komanso kutentha kwapakati. Komabe, panthawi yopanga ndikugwiritsa ntchito injiniyo, makina opangira mafuta amatha kusagwira ntchito bwino chifukwa cha zinthu zina zosayenera.
Pamene chilolezo chogwira ntchito chonyamula ndi chochepa kwambiri ndipo kugwirizana pakati pa kunyamula ndi tsinde kapena chipinda chonyamula ndi chotayirira, kumayambitsa mabwalo othamanga; pamene mgwirizano wa axial woyenerera wa chimbalangondo umasokonekera kwambiri chifukwa cha mphamvu ya axial; kukwanira kosayenera pakati pa zonyamula ndi mbali zofananira kumayambitsa kuyanika Zinthu zosafunikira monga kutayidwa kwa mafuta kuchokera pabowo lokhalamo kumapangitsa kuti kunyamula kutenthetse panthawi yoyendetsa galimoto. Mafutawa adzawonongeka ndi kulephera chifukwa cha kutentha kwambiri, zomwe zimapangitsa kuti makina oyendetsa galimoto awonongeke kwambiri m'kanthawi kochepa. Chifukwa chake, kaya ndi mapangidwe kapena kupanga ma mota, komanso kukonzanso pambuyo pake ndikusamalira injini, kukula kwa ubale wofananira pakati pa magawowo kuyenera kuwongoleredwa.
Shaft current ndi chiwopsezo chomwe sichingalephereke pama motors akulu, makamaka ma mota okwera kwambiri komanso ma mota osinthasintha. Shaft current ndivuto lalikulu kwambiri pamachitidwe onyamula katundumotere wopanda maziko. Ngati njira zoyenera sizikutengedwa, njira yoberekera imatha kuwonongeka mumasekondi pang'ono chifukwa cha shaft pano. Kugawanika kumachitika mkati mwa maola khumi kapena ngakhale maola angapo. Vuto lamtunduwu limadziwonetsera ngati kunyamula phokoso ndi kutentha koyambirira kwa kulephera, kutsatiridwa ndi kulephera kwa mafuta chifukwa cha kutentha, ndipo mkati mwa nthawi yochepa, vuto la kugwiritsira ntchito shaft chifukwa cha kutulutsa ablation kumachitika. Pazifukwa izi, ma mota okwera kwambiri, ma frequency frequency motors, ndi low-voltage high-power motors atengapo mbali zofunikira pakupanga, siteji yopangira, kapena siteji yogwiritsira ntchito. Pali awiri omwe amafanana. Imodzi ndikudula dera (monga kugwiritsa ntchito ma insulated bearings, Insulating end caps, etc.), ina ndi njira yodutsa pano, ndiko kuti, kugwiritsa ntchito burashi ya kaboni yokhazikika kuti itsogolere pakalipano kuti mupewe kuukira kwa makina onyamula. .
