Abstract
The present disclosure relates to a hybrid bearing that effectively combines load-bearing capacity of a magnetic bearing and damping performance of a foil bearing by installing a pedestal between poles of the magnetic bearing and coupling the foil bearing inside the pedestal, thereby eliminating restrictions on thickness and height of foils and maintaining a constant gap between the magnetic bearing and a rotating shaft.
Claims6
A hybrid magnetic-foil bearing supporting a rotating shaft comprising:
- a magnetic electrode part in which a plurality of poles wound around a coil are arranged in a circumferential direction;
- a pedestal including mounting parts, each of which is positioned between every two adjacent poles of the plurality of poles and has a groove shape inward;
- a bump foil accommodated in the mounting part;
- and
- a top foil installed on the bump foil and facing the rotating shaft.
