ABSTRACT:
A gas bearing for rapidly rotating parts, particularly in textile machines, including two support members mounted on a base plate, thin foils attached to each of the support members by means of clamping plates such that the foils partially embrace a rotor shaft or other part to be positioned, and a drive belt which rotates the rotor shaft and maintains the shaft positioned against the foils. Additionally a movable hose is attached to a foil whereby gas can be introduced between the rotor shaft and the foil by means of perforations in the foil. A similar supporting gas film is created at an end of the rotor shaft. Centrally located axial passages in the rotor shaft and a positioning magnet introduce gas into the shaft and through radial ducts in the shaft to provide a thin gas film for supporting the shaft. According to a further embodiment a gas bearing is provided for use with a shaft which is driven independently of the bearing.
