Kuthamanga kozungulira kwa chimbalangondo kumagwira ntchito yofunika kwambiri pakutentha kwa chinthucho.Mtundu uliwonse wonyamula uli ndi liwiro lake, lomwe limatsimikiziridwa ndi mawonekedwe akuthupi monga kukula, mtundu ndi kapangidwe.Kuthamanga kwa malire kumatanthawuza kuthamanga kwakukulu kogwira ntchito (Kawirikawiri amagwiritsidwa ntchito r / min), kupitirira malirewa kumapangitsa kutentha kwa kutentha kukwera, mafuta odzola ndi owuma, ndipo ngakhale kunyamula kumamatira.Kuthamanga kwamtundu wofunikira pakugwiritsa ntchito kumathandizira kudziwa mtundu wamtundu womwe mungagwiritse ntchito.Makatalogu ambiri opanga katundu amapereka malire pazogulitsa zawo.Zatsimikiziridwa kuti kugwira ntchito pa kutentha pansi pa 90% ya liwiro la malire kuli bwino.

Kuyang'ana zofunikira za liwiro logwira ntchito pamayendedwe, auzeni aliyense zotsatirazi:

1. Mapiritsi a mpira ali ndi malire othamanga kwambiri komanso kulondola kwa kasinthasintha kusiyana ndi mayendedwe odzigudubuza, choncho mayendedwe a mpira ayenera kukhala okondedwa pamene akuyenda mofulumira kwambiri.

2. Pansi pa m'mimba mwake wamkati, ang'onoang'ono akunja, ang'onoang'ono ang'onoang'ono, ndi ang'onoang'ono a centrifugal inertia mphamvu ya chinthu chogubuduza panjira yachilendo panthawi yogwira ntchito, choncho ndi yoyenera kugwira ntchito mofulumira kwambiri..Chifukwa chake, pa liwiro lalitali, zonyamula zokhala ndi ma diameter ang'onoang'ono akunja pamndandanda womwewo wa m'mimba mwake ziyenera kugwiritsidwa ntchito.Ngati kunyamula kokhala ndi mainchesi ang'onoang'ono akunja kumagwiritsidwa ntchito ndipo mphamvu yonyamula sikwanira, kunyamula komweko kumatha kukhazikitsidwa palimodzi kapena kuganiziridwa mosiyanasiyana.

3. Zinthu ndi kapangidwe ka khola zimakhudza kwambiri pa liwiro la kubala.Khola lolimba limalola kuthamanga kwambiri kuposa khola losindikizidwa, ndipo khola lolimba lamkuwa limalola kuthamanga kwambiri.

Nthawi zambiri, pogwira ntchito yothamanga kwambiri, mayendedwe a mpira wakuya, ma mayendedwe olumikizana ndi ma cylindrical roller ayenera kugwiritsidwa ntchito;pakakhala ntchito yotsika liwiro, mayendedwe a tapered roller angagwiritsidwe ntchito.Liwiro lochepera la mayendedwe odzigudubuza nthawi zambiri amakhala pafupifupi 65% ya mayendedwe ozama a mpira, 70% ya ma cylindrical roller bearings, ndi 60% ya mayendedwe apila olumikizana.Mapiritsi a mpira wa thrust ali ndi liwiro lotsika ndipo angagwiritsidwe ntchito pamapulogalamu otsika kwambiri.
