Air foil Bearing

Research object

 Hydrodynamic air bearings have outstanding advantages on high speed and compact systems of turbo-machines. Recently, oil-free turbo-machinery implements gas foil bearing to ensure low friction and high load-capacity and stability.

 

 KIST researched static performance such as oil-free gas foil journal bearings(GFJBs). Static performance variable of GFJBs are load capacity, bearing torque and bearing temperature. From this result, we conducted static performance test of GFJBs.

 

Thus, we developed as followings;

-. Load capacity measurement system

-. Bearing torque measurement system

 

Application

-. Ultra high speed PM motor

-. Turbo Blower, Turbo compressor

-. Gas turbine, Turbo chrager
