Kufotokozera Kwachidule:

● Mfundo zinayi kukhudzana mpira kubala ndi mtundu wa olekanitsidwa mtundu kubala, komanso tinganene kuti akonzedwa aang'ono kukhudzana mpira kubala amene akhoza kunyamula bidirectional axial katundu.

● Ndi mzere umodzi ndi mizere iwiri ya angular kukhudzana ndi mpira, kuthamanga kwambiri.

● Zimangogwira ntchito bwino pamene mfundo ziwiri zolumikizana zapangidwa.

● Kawirikawiri, ndizoyenera kunyamula katundu wa axial, katundu wamkulu wa axial kapena ntchito yothamanga kwambiri.

Mawu Oyamba

Mipira yolumikizana ndi mfundo zinayi ndi mizere yolumikizana ndi mizere yolumikizana ndi mizere yolowera yomwe idapangidwa kuti izithandizira kunyamula ma axial mbali zonse ziwiri.Kwa katundu wa axial wopatsidwa, katundu wochepa wa radial angathenso kuthandizidwa.The mayendedwe ndi olekanitsidwa, mwachitsanzo mphete akunja ndi mpira ndi khola msonkhano akhoza wokwera mosiyana ndi awiri mkati mphete.

Magawo onse awiri amkati a Explorer ali ndi mapewa opumira.Izi zimapangitsa kuti mafuta aziyenda bwino pamene chonyamuliracho chikugwiritsidwa ntchito limodzi ndi cylindrical roller bear.Kuphatikiza apo, zotsalira izi zitha kugwiritsidwa ntchito kuti zithandizire kutsika.

Mbali ndi Ubwino

  • ● Imanyamula katundu wa axial mbali zonse ziwiri
  • ● Malo ochepa axial
    Ma bere awa amatenga malo ochepa kwambiri a axial kuposa mizere iwiri.
  • ●Kunyamula katundu wambiri
    Mipira yambiri imaphatikizidwa, zomwe zimapangitsa kuti katundu wake azinyamula katundu wambiri.
  • ● Mapangidwe olekanitsidwa
    Mphete yamkati yogawanika imapangitsa kuti ikhale yosavuta kukweza ndi kutsika kwa chonyamulira.
  • ● Mafuta oyenda bwino
  • Mapindikidwe a mphete amkati akakhala ndi mphamvu zolimba kwambiri.

Ntchito

Pamene katundu woyera wa axial ukugwiritsidwa ntchito, mpira ndi mphete zimapanga mgwirizano wa mfundo ziwiri zomwe zimatha kunyamula katundu wa axial bidirectional.Mipira yolumikizana ndi mfundo zinayi zili bwino.

Yokhala ndi torque yonyamula, imakhala ndi mizere iwiri yolumikizana ndi mpira wolumikizana ndi mizere iwiri.Mpira wa nsonga zinayi ukhoza kugwira ntchito bwino pokhapokha mfundo ziwirizo zitapangidwa.Choncho, nthawi zambiri ndi yoyenera kwa axial katundu wangwiro kapena katundu wamkulu wa axial pansi pa katundu wophatikizika wa kukhudzana kwa mfundo ziwiri, mfundo zinayi zolumikizana ndi mpira wokhala ndi malire othamanga ndi okwera, komanso oyenera pazochitika zothamanga kwambiri.

Makhalidwe

Mpira wokhala ndi mfundo zinayi zolumikizana ndi mawonekedwe olekanitsidwa, ndipo chonyamula chimodzi chingathe m'malo mwa mpira wolumikizana ndi angular ndi kuphatikiza kutsogolo kapena kuphatikiza kumbuyo.

Imatha kunyamula katundu wa radial ndi bidirectional axial load, ndipo imatha kuchepetsa kusuntha kwa axial mbali ziwiri, koma imakhala ndi malo ocheperako kuposa momwe mizere iwiri yapawiri yolumikizana ndi mpira.

Poyerekeza ndi mayendedwe ena a mpira, mayendedwe anayi olumikizana ndi mpira amakhala ndi chilolezo chaching'ono cha axial komanso kuthamanga kwa malire pamene chilolezo cha radial chili chofanana.

Mipira yolumikizana ndi mfundo zinayi ndi yoyenera kunyamula katundu wa axial kapena kuphatikizika kwa axial ndi ma radial potengera katundu wa axial.Chifukwa cha mphete yamkati ya theka (kapena mphete yakunja), chiwerengero cha mipira chikuwonjezeka ndipo mphamvu yobereka ndi yaikulu.

Pansi pazikhalidwe zogwirira ntchito, mtundu uwu wa kubereka ukhoza kupanga ngodya yokhudzana ndi kunyamula katundu wa axial kumbali iliyonse, ndipo mpira wachitsulo umakhudzana ndi njira zamkati ndi zakunja panthawi imodzi kuti tipewe kukangana kwakukulu kotsetsereka kumalo okhudzidwa.Choncho, kubereka sikuyenera kugonjetsedwa ndi mphamvu za radial ndi katundu.
