Kubereka

moyo
Pansi pa katundu wina, chiwerengero cha zosintha kapena maola kuti akuberekazokumana nazo zisanachitike kubowola kumatchedwakuberekamoyo.
Moyo wa chimbalangondo umatanthauzidwa ndi kuchuluka kwa zosinthika (kapena maola ogwirira ntchito pa liwiro linalake): mkati mwa moyo uno, kunyamula kuyenera kukhala ndi kuwonongeka koyambirira kwa kutopa (kuphulika kapena kuphulika) pazingwe zake zilizonse kapena zinthu zogudubuza. Komabe, kaya mu zoyezetsa zasayansi kapena ntchito kwenikweni, zikhoza kuonekeratu kuti moyo weniweni wamayendedwendi maonekedwe omwewo pansi pa zikhalidwe zomwezo zogwirira ntchito ndizosiyana kwambiri. Kuphatikiza apo, pali matanthauzo angapo osiyanasiyana a "moyo", womwe umatchedwa "moyo wogwira ntchito", womwe ukuwonetsa moyo weniweni womwe kubereka kungathe kukwanitsa kulephera chifukwa cha kuvala, kuwonongeka nthawi zambiri sikumayambitsa kutopa, koma Chifukwa cha kuvala, dzimbiri, kuwonongeka kwa chisindikizo, etc.
In order to determine the standard of bearing life, the bearing life and reliability are related.

Chifukwa cha kusiyana kwa kupanga mwatsatanetsatane ndi kufanana kwa zinthu, ngakhale mtanda womwewo wa mayendedwe a zinthu zomwezo ndi kukula kwake, zomwe zimagwiritsidwa ntchito pansi pa ntchito zomwezo, zimakhala ndi nthawi zosiyana. Ngati moyo wowerengera ndi 1 unit, moyo wautali kwambiri ndi mayunitsi 4, wamfupi kwambiri ndi 0.1-0.2 unit, ndipo chiŵerengero chautali kwambiri mpaka waufupi ndi nthawi 20-40. 90% ya ma bearings samatulutsa dzimbiri, ndipo kuchuluka kwa zosinthika kapena maola omwe akumanapo amatchedwa moyo wowerengera.

Adavotera dynamic katundu
Pofuna kufananiza mphamvu yobereka ya chimbalangondo motsutsana pitting dzimbiri, pamene oveteredwa moyo wakuberekaimanenedwa kukhala ma revolutions miliyoni imodzi (106), katundu wochuluka womwe ungathe kuthandizidwa ndi katundu wofunikira kwambiri, woimiridwa ndi C.
Ndiko kunena kuti, pansi pa zochita za oveteredwa zazikulu katundu C, kudalirika kwa mtundu uwu wakuberekakugwira ntchito yosintha miliyoni imodzi (106) popanda kulephera ndi 90%. Kukula kwa C, kumapangitsa kuti mphamvu yobereka ikhale yokwera.
Kwa ma dynamic load rating
1. Kutulutsa kwa radial kumatanthawuza kunyamula koyera
2. Mipira ya thrust imatanthawuza katundu wa axial

3. Kukankha kwa radialkuberekaimatanthawuza gawo la radial lomwe limapanga kusamuka koyera
