Inani lokumelana nokushisa kwama-bearings okushisa okuphezulu alinqunyelwe enanini, futhi ngokuvamile lihlobene nezinto ezisetshenziswa ku-bearings. Ngokuvamile, izinga lokushisa lingahlukaniswa ngama-degrees angu-200, ama-degrees angu-300, ama-degrees angu-40, ama-degrees angu-500, kanye nama-degrees angu-600. Amazinga okushisa asetshenziswa kakhulu angama-300 nama-500;
Ama-bearings okushisa okuphezulu angama-600 ~ 800 degrees ngokuvamile angahlukaniswa abe izinhlobo ezimbili, wonke ama-bearings okushisa okuphezulu ensimbi okushisa okuphezulu kanye nama-bearings okushisa aphezulu e-ceramic hybrid;
Ama-bearings angu-800-1200 okushisa okuphezulu avame ukusebenzisa i-silicon nitride ceramics njengezinto zokusetshenziswa ukuze kuthathelwe indawo izindawo zokushisa okuphezulu okunzima ukuzifeza ngensimbi.
Izinhlobo zesakhiwo sama-bearings okushisa okuphezulu yilezi ezilandelayo:
1. Ukuthwala okugcwele kwebhola lokushisa eliphezulu
Isakhiwo sigcwele izakhi ezigoqekayo, futhi izinto zokwakha yilezi: insimbi ethwalayo, insimbi ye-alloy enokushisa okuphezulu kanye ne-silicon nitride. Phakathi kwazo, i-bearing ye-full-ball ephezulu eyenziwe ngensimbi ethwalayo ingamelana nokushisa okuphezulu okungu-150 ~ 200℃, i-bearing ye-full-ball eyenziwe ngensimbi ye-alloy enokushisa okuphezulu ingamelana nokushisa okuphezulu okungu-300 ~ 500℃, kanye ne-bearing ye-full-ball eyenziwe nge-silicon nitride ingamelana nokushisa okuphezulu okungu-800 ~ 1200℃.
2. Amabheringi asheshayo futhi anokushisa okuphezulu
Isakhiwo sihlanganisa ikheji, isivinini siphezulu, futhi izinto zokwakha ngokuvamile zenziwe ngensimbi ye-alloy enokushisa okuphezulu
Indlela yokukhetha amabheringi okushisa okuphezulu kufanele ikhethwe ngokwezimo zangempela zokusetshenziswa. Isibonelo, uma indawo inzima futhi isivinini siphezulu, kufanele kukhethwe ikheji, indandatho yokuvala, kanye negrisi yokushisa ephezulu engenisiwe.
