Moyo wobereka

Kuwerengera Moyo wa Kunyamula: Katundu ndi Liwiro la Kunyamula

Moyo wa kuberekera nthawi zambiri umayesedwa pogwiritsa ntchito kuwerengera kwa L10 kapena L10h. Kuwerengera kumeneku kwenikweni ndi kusiyana kwa ziwerengero za miyoyo ya kuberekera payokha. Moyo wa beering wa L10 monga momwe tafotokozera mu miyezo ya ISO ndi ABMA umachokera pa moyo womwe 90% ya gulu lalikulu la ma bearing ofanana adzafika kapena kupitirira. Mwachidule, kuwerengera kutalika kwa 90% ya ma bearing kudzakhalepo mu ntchito inayake.

Kumvetsetsa Moyo Wopangira Ma Roller Bearing a L10

L10h = Moyo woyambira wa mavoti mu maola

P = Mphamvu yofanana

C = Kuyesa koyambira kwamphamvu kwamphamvu

n = Liwiro lozungulira

p = 3 ya ma bearing a mpira kapena 10/3 ya ma roller bearing

L10 - kusintha kwa kulemera koyambira

L10s - kuwerengera katundu woyambira patali (KM)

 

Monga mukuonera kuchokera mu equation pamwambapa, kuti mudziwe moyo wa L10 wa bearing yeniyeni, katundu wa radial ndi axial wogwiritsidwa ntchito amafunika komanso liwiro lozungulira la application (RPM). Chidziwitso chenicheni cha momwe ntchito imakwezedwera chimaphatikizidwa ndi ziwerengero za katundu wonyamula kuti mudziwe katundu wophatikizana kapena katundu wofanana ndi Dynamic womwe umafunika kuti mumalize kuwerengera moyo.

Kuwerengera & Kumvetsetsa Kubereka Moyo

P = Katundu Wophatikizana (Katundu Wofanana Wolimba)

X = Chinthu cholemera cha radial

Y = Chinthu cholemera cha axial

Fr = Kulemera kwa radial

Fa = Kulemera kwa Axial

Dziwani kuti L10 Life Calculation siganizira kutentha, mafuta odzola ndi zinthu zina zofunika kwambiri kuti pakhale moyo wokwanira wa bearing. Kusamalira bwino, kusamalira, ndi kukhazikitsa zonse zimangoganiziridwa. Ichi ndichifukwa chake zimakhala zovuta kwambiri kuneneratu kutopa kwa bearing komanso chifukwa chake ma bearing osakwana 10% amakumana kapena kupitirira nthawi yawo yokwanira ya kutopa.

Kodi N’chiyani Chimachititsa Moyo wa Utumiki wa Bearing?

Tsopano popeza mwamvetsetsa bwino momwe mungawerengere nthawi yoyambira yotopa komanso nthawi yomwe ma bearing ozungulira amakhala, tiyeni tiyang'ane pazinthu zina zomwe zimatsimikiza nthawi yomwe amakhala ndi moyo. Kuwonongeka kwachilengedwe ndi komwe kumayambitsa kuwonongeka kwa ma bearing, koma ma bearing amathanso kulephera msanga chifukwa cha kutentha kwambiri, ming'alu, kusowa kwa mafuta kapena kuwonongeka kwa zisindikizo kapena khola. Kuwonongeka kwa ma bearing nthawi zambiri kumachitika chifukwa chosankha ma bearing olakwika, kulakwitsa pakupanga kwa zigawo zozungulira, kuyika kolakwika kapena kusowa kosamalira & mafuta oyenera.
