OAV Advanced Aerodynamic Bearings

​

The development of foil-air-bearings began in the early 1970s to provide rotational guidance for gas turbine shafts. Foil bearings, also known as a foil air bearings, is a type of air bearing where the surface is supported by a compliant, spring-loaded foil journal lining. Once the surface is spinning fast enough, the air pushes the foil away from the surface so that no contact and no wear occurs. The surface and foil are separated by the high pressure from the air, generated by the rotation that pulls gas into the bearing via the viscosity effects. OAV Foil Air Bearings can operate under the most demanding systems without the requirement for external supply. OAV's advanced method makes the OAV foil-air bearings unmatchable.  Contact OAV engineers for more details.

OAV's Novel Design - Aerodynamic And Aerostatic Air Bearing Combination. 

The purpose of this novel design is for OAV to focus on eliminating the adverse effects of rotational speed, unbalanced eccentricity, and rotor mass on the non-linear response. We use a combined approach that treats air and structure as two computational areas to solve common issues, reach higher load capacities, better damping effect, and eliminate the start-up and stop concerns of foil air bearings.
