Thekusewera mpiraadapangidwa kuti azitha kupirira pothamanga kwambiri ndipo amapangidwa ndi mphete ya gasket yokhala ndi njira yothamangitsira mpira.Chifukwa mpheteyo ndi yooneka ngati khushoni, mayendedwe a mpira wokhomedwa amagawidwa m'mitundu iwiri: mtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wamtundu wozungulira komanso mtundu wamtundu wozungulira wozungulira.Kuphatikiza apo, kunyamula kumatha kupirira katundu wa axial, koma osati katundu wa radial.Mpira wothamangakuberekazikuchokera: kukankhira mpira kubala wapangidwa ndi zigawo zitatu: mpando mphete, kutsinde mphete ndi zitsulo mpira khola msonkhano.Mphete yoyezera yokhala ndi tsinde ndi mphete yoyezera ndi nyumba.

Mtundu:

Malinga ndi mphamvu, akusewera mpiraakhoza kugawidwa mu unidirectional thrust mpira kubala ndi bidirectional kukankha mpira kubala.Unidirectional thrust mpira mayendedwe amatha kupirira unidirectional axial katundu.Bidirectional thrust mpira wonyamula, imatha kupirira bidirectional axial load, momwe mphete ya shaft ndi shaft zimakwanira.Kukhala ndi nkhope yozungulira yozungulira ya mphete kumakhala ndi machitidwe odzigwirizanitsa okha, omwe amatha kuchepetsa kulakwitsa kwa kukhazikitsa.Kuthamanga mpira mayendedwe sangakhoze kupirira zozungulira katundu, malire liwiro ndi otsika.

Mawonekedwe:

1. Pali mitundu iwiri: njira imodzi ndi iwiri.

2. Pofuna kulola cholakwika unsembe, kaya unidirectional kapena bidirectional, mukhoza kusankha spherical self-aligning ozungulira khushoni mtundu kapena ozungulira mphete mtundu.

3. Chitsulo chapamwamba kwambiri - pogwiritsa ntchito zitsulo zoyera kwambiri zomwe zimatha kupititsa patsogolo moyo wa zitsulo mpaka 80%.

4. Ukadaulo wapamwamba wamafuta - Tekinoloje yamafuta a NSK imatha kuwonjezera moyo wamafuta ndikuwongolera magwiridwe antchito.

5. Mpira wachitsulo wapamwamba kwambiri - chete komanso wosalala pa liwiro lalikulu.

6. Kuyika zolakwika kungaloledwe pogwiritsa ntchito ferrule muzosankha.

Cholinga cha mpira wothamanga:

Ndiwoyenera kunyamula mbali imodzi ya axial katundu ndi magawo otsika kwambiri, monga mbedza ya crane, pampu yowongoka, centrifuge yowongoka, jack, low speed reducer, etc.
Mphete ya shaft, mphete yapampando ndi thupi lozungulira la chonyamulira zimasiyanitsidwa ndipo zimatha kusonkhanitsidwa ndikuphatikizidwa motsatana.
