Title:
AIR FOIL BEARING
Document Type and Number:
WIPO Patent Application WO/2017/086732
Kind Code:
A1
Abstract:
The present invention relates to an air foil bearing. The present invention is configured such that the rigidity of bumps can be controlled by varying the width of single bumps, and has an advantage in managing the height of the bearing, since a wedge effect is realized only under the weight of an oil film as initial bumps all have the same height. Also, the present invention is capable of stably damping an impact exerted in the direction of the rotation axis of a rotor, improving bearing power, and minimizing an impact resulting from damping and has the effect of improving the durability of the air foil bearing.
