Abstrakt
Air-foil technology is an interesting alternative for classic rolling or oil
bearings in turbomachinery. It ensures low power losses, do not require external
lubrication or pressurization and is capable of working with high rotational speeds.
Numerous studies brought significant improvement in materials and design solutions
for the aerodynamic shaft support system. The paper presents effects of modification
performed by adding intermediate foil to typical structure of air-foil bearing. The
main aim of the investigation was focused on analyze of its influence on characteristic
parameters and exploitation properties of operating bearing, i.e. bearing load capacity
and bearing resistance to thermal runaway phenomenon [4]. The thermal runaway is
also known as foil bearing thermal instability. The tests confirmed proper behavior of
the modified device and brought new knowledge in air-foil technology field.
