Kuthamanga kwa galimoto yonyamula katundu kumachepa makamaka chifukwa cha kukwera kwa kutentha komwe kumachitika chifukwa cha kukangana ndi kutentha mkati mwa chitsanzo chonyamula.Liwiro likadutsa malire ena, kunyamula sikungathe kupitiliza kuyendayenda chifukwa cha kuyaka, etc. Liwiro lochepetsetsa la kunyamula limatanthawuza kuchuluka kwa malire a liwiro lomwe kunyamula kumatha kuzungulira mosalekeza popanda kutulutsa kutentha kwamphamvu komwe kungayambitse. amayaka.Choncho, kuchepetsa liwiro la kunyamula kumadalira zinthu zosiyanasiyana monga mtundu, kukula ndi kulondola kwa kunyamula, njira yothira mafuta, ubwino ndi kuchuluka kwa mafuta, zinthu ndi mtundu wa khola, ndi katundu.

Kuthamanga kocheperako kwa ma beya osiyanasiyana pogwiritsa ntchito mafuta opaka mafuta ndi kuthira mafuta (mafuta osambira osambira) amalembedwa patebulo lililonse.Miyezo imayimira miyeso yomwe idapangidwa pansi pa katundu wamba (C / P≥13, Fa/Fr≤0.25 kapena choncho ) ndiye malire a liwiro lozungulira pozungulira pa liwiro lotsika.Kuwongolera liwiro la malire: chikhalidwe cha katundu C/P <13 (ndiko kuti, mphamvu yofananira P imaposa pafupifupi 8% ya C), kapena pamene axial katundu mu katundu wophatikizidwa adutsa 25% ya katundu wa radial. , iyenera Kugwiritsa ntchito equation (1) kukonza liwiro la malire.ndi=f1·f2·n……………(1) Malire okonzedwa, rpm, kuwongolera kokwanira kokhudzana ndi chikhalidwe cha katundu (mkuyu 1), koyenere yowongolera yokhudzana ndi katundu wotsatira (mkuyu 2), liwiro la malire pansi pazikhalidwe zambiri, rpm (onani tebulo la kukula) mphamvu zoyendetsera mphamvu, N{kgf} katundu wofanana ndi mphamvu, N{kgf} radial load, N{kgf} axial load, N{kgf} pole motor ndi kuthamanga kwambiri Kusamala: Bearings mukamazungulira pamwamba. liwiro, makamaka pamene liwiro liri pafupi kapena kupitirira 70% ya liwiro la malire lolembedwa pa tebulo la dimension, zinthu zotsatirazi ziyenera kutsatiridwa: (1) Gwiritsani ntchito mayendedwe olondola kwambiri (2) Kusanthula chilolezo chamkati cha mayendedwe. (ganizirani kukwera kwa kutentha mkati mwa bere) Kuchepetsa kuchotsera) (3) Onani mtundu wa zinthu za khola (4) Unikani njira yothira mafuta.
