Inani lokumelana nezinga lokushisa lama-bearings okushisa aphezulu alinqunyelwe inani, futhi ngokuvamile lihlobene nezinto ezisetshenziswa ekuthwaleni.Ngokuvamile, izinga lokushisa lingahlukaniswa ngama-degree angu-200, ama-300 degrees, ama-40 degrees, ama-500 degrees, nama-degree angu-600.Amazinga okushisa asetshenziswa kakhulu angama-300 no-500;
600 ~ 800 degrees izinga lokushisa eliphezulu amabombo ngokuvamile zingahlukaniswa zibe izinhlobo ezimbili, zonke izinga lokushisa eliphezulu steel izinga lokushisa eliphezulu amabombo kanye Ceramic hybrid izinga lokushisa eliphezulu;
800 ~ 1200 ama-high-temperature bearings ngokuvamile asebenzisa izitsha zobumba ze-silicon nitride njengezinto zokusetshenziswa ukuze zithathele indawo indawo enezinga lokushisa eliphezulu okunzima ukuyithola ngensimbi.
Izinhlobo zesakhiwo zama-bearings okushisa aphezulu zimi kanje:
1. Ibhola eligcwele lokushisa eliphezulu elithwala
Isakhiwo sigcwele izakhi ezigoqayo, futhi izinto ezisetshenziswayo yilezi: insimbi ethwalayo, insimbi ye-alloy yokushisa ephezulu kanye ne-silicon nitride.Phakathi kwazo, i-full-ball-high-temperature bearing eyenziwe ngensimbi enensimbi ingamelana nezinga lokushisa eliphakeme lika-150 ~ 200 ℃, i-full-ball bear eyenziwe nge-high-temperature alloy steel ingakwazi ukumelana nezinga lokushisa elingu-300 ~ 500 ℃, futhi eligcwele. -ibhola elenziwe nge-silicon nitride lingamelana nezinga lokushisa eliphakeme lika-800 ~ 1200℃.
2. Ama-bearings anesivinini esikhulu namazinga okushisa aphezulu
Isakhiwo sihlanganisa ikheji, ijubane liphezulu, futhi impahla ngokuvamile yenziwe ngensimbi ye-alloy esezingeni eliphezulu.
Indlela yokukhetha ama-bearings asezingeni eliphezulu kufanele ikhethwe ngokuvumelana nezimo zangempela zohlelo lokusebenza.Isibonelo, uma imvelo inokhahlo futhi ijubane lingaphezulu, ikheji, iringi yokuvala, kanye namafutha aphuma kwamanye amazwe anezinga eliphezulu lokushisa kufanele kukhethwe.
