01. Kusankha mabearing: NNU895Y3 kumapeto kwa chakudya, NNUP895Y3 kumapeto kwa chotulutsira

Malinga ndi momwe kasitomala amagwirira ntchito, mphero ya mpira imapangidwa ndi silinda, shaft yopanda kanthu, mpando waukulu woperekera katundu, ndi chitsamba choperekera katundu. Mphamvu yozungulira idzapangidwa ponyamula katundu, ndipo mphero yokhala ndi mphamvu yayikulu yoperekera katundu iyenera kusankhidwa. Tapanga mphero yozungulira ya mizere iwiri yakunja yokhala ndi mphamvu yonyamula katundu wamphamvu, yolimba bwino, yofewa mosavuta, yodalirika kwambiri, yolumikizidwa ku makina opera, ndipo imatha kugwira ntchito bwino ikasuntha mozungulira. Kudzera mu kuwerengera kwa moyo, palibe vuto pakutsimikizira maola 43800.

02. Kukonza kapangidwe kake:

Malinga ndi momwe kasitomala amagwirira ntchito:

1. Mphero yoyambirira ya mpira imagwiritsa ntchito shaft yopanda kanthu ndi chitsamba chonyamulira poyatsira friction, ndipo mafuta ochepa amapanga filimu yamafuta kuti azitha kufalikira. Pogwiritsidwa ntchito kwenikweni, pamene zinthuzo zikuwonjezeka, katundu wa chitsamba chonyamulira umawonjezeka. Ngati kutentha komwe kumapangidwa ndi friction sikutha nthawi yake, kumabweretsa ngozi ya "Burning tile", kotero tidakonza friction yonyamulira ya bearing pad, tidagwiritsa ntchito kapangidwe ka rolling friction, ndikupanga double row roller bearing.

2. Mphero youma idzatalikira chifukwa cha kutentha kwakukulu kwa zinthu zomwe zikubwera komanso kutentha komwe kumachitika chifukwa cha ntchitoyo. Zimapangitsa kuti thupi la silinda liziyenda mbali ziwiri ndikuthamanga mosakhazikika. Chifukwa chake, kuyenda ndi kukhazikika kwa silinda ya mphero kumapangidwa, malo olowera amapangidwa opanda nthiti, ndipo malo otulukira amapangidwa ndi nthiti ziwiri, zomwe zimakwaniritsa ntchito yokhazikika ya silinda.

3. Chifukwa cha kulemera kwake komanso momwe mipira yachitsulo imagwirira ntchito komanso zitsulo zomangira, silinda imapindika ndikusokonekera kuti ipange kupindika, zomwe zimafuna kuti bearing yozungulira ikhale yodziyimira yokha, apo ayi silindayo siili mu mzere womwewo, zomwe zimapangitsa kuti bearing iwonongeke. Chifukwa chake, tapanga zofunikira zodziyimira yokha pa bearing yozungulira. M'mimba mwake wakunja wa mphete yakunja ya bearing wapangidwa ngati arc, zomwe zimathetsa vuto la silinda kukhala yosagwirizana.

03. Chiwonetsero cha zotsatira:

Mwa kuphatikiza momwe zida zimagwiritsidwira ntchito, tapanga mtundu watsopano wa bearing ya mpira kuti ikwaniritse zosowa za kasitomala. Nthawi yogwira ntchito yomwe imabwera chifukwa cha vuto la "kuwotcha matailosi" kwa kasitomala imachepetsedwa kwambiri, zomwe zimapulumutsa ogwiritsa ntchito 80% -90% ya mafuta opaka, magetsi opitilira 8%, komanso kusunga mphamvu yonse yoposa 10% -15%. Mphamvu ya mota yamagetsi yomwe imagwiritsidwa ntchito mu mpira imatha kuchepetsedwa ndi 13% -20%, ndipo mphamvu yonyamula katundu wa thupi lopera imatha kuwonjezeredwa ndi 15% -20%, zomwe zimapangitsa kuti mphero ya mpira igwire bwino ntchito.
