Abstract
The present invention relates to an airfoil bearing applied for an ultra-high speed operation of a rotating apparatus, and more particularly, to an airfoil bearing having a structure in which a bump foil key at one end of a bump foil and a bump foil key at the other end of the bump foil are formed asymmetrically, which may improve driving performance and durability performance against disturbance.
Claims16
An airfoil bearing comprising:
- a bearing housing having a cylindrical structure;
- a top foil disposed to be spaced apart from an inner side of the bearing housing;
- and
- a bump foil disposed between the bearing housing and the top foil,
- wherein in an inner peripheral surface of the bearing housing, a top foil key groove, into which a pair of top foil keys formed by bending two opposite ends of the top foil radially outward are inserted, is formed, and a bump foil key groove, into which a pair of bump foil keys formed by bending two opposite ends of the bump foil radially outward are inserted, is formed, and
- wherein when any one of the pair of bump foil keys is referred to as a first bump foil key and the remaining one of the pair of bump foil keys is referred to as a second bump foil key, the first bump foil key and the second bump foil key are formed asymmetrically.
