Abstract
The present disclosure relates to a hybrid thrust bearing that combines an airfoil bearing and a magnetic bearing to support a rotating shaft with a disk-shaped thrust disk, and the magnetic bearing includes a disk-shaped housing into which the rotation shaft is inserted through a hole formed in a center and facing the thrust disk, a ring-shaped inner pole part formed around the hole on one side of the housing facing the thrust disk, a ring-shaped outer pole part disposed outside the inner pole part, an attachment part provided between the inner pole part and the outer pole part, and a coil stored in the attachment part, wherein a part of the airfoil bearing is inserted into the attachment part.
Claims6
A hybrid thrust bearing that combines an airfoil bearing and a magnetic bearing to support a rotating shaft with a disk-shaped thrust disk,
- the magnetic bearing comprising:
- a disk-shaped housing into which the rotation shaft is inserted through a hole formed in a center and facing the thrust disk;
- a ring-shaped inner pole part formed around the hole on one side of the housing facing the thrust disk;
- a ring-shaped outer pole part disposed outside the inner pole part;
- an attachment part provided between the inner pole part and the outer pole part;
- and
- a coil stored in the attachment part,
- wherein a part of the airfoil bearing is inserted into the attachment part,
- wherein the airfoil bearing includes an airfoil pad that covers an upper surface of the coil and is installed on the attachment part, and
- wherein a depth of the attachment part is a combined thickness of the coil and the airfoil pad.
