Abstract
An aerodynamic radial bearing has two foil sections located in a gap between an outer bearing shell (1) and the bearing shaft. The foil sections encircle or loop around the bearing shaft in several layers and include an inner foil section and an outer foil section. Each section may have one or several foil or band portions. The inner foil section closer to the shaft forms the bearing running surface and the outer foil section closer to the shell wall forms a support of predetermined elasticity or desired stiffness. The outer end of the outer foil section is secured to the bearing shell. At least one foil or band portion of the inner foil section is wrapped in opposition to the direction (D) of rotation of the shaft (2) and is connected (at 5, 10 11) to at least one further foil or band portion of the outer foil section which is wrapped in the direction (D) of rotation of the shaft (2). These features eliminate the troubles encountered heretofore in operation of such bearings due to contaminant particles since these particles can no longer accumulate in the running gap.
