Gas bearing and method for producing same

A gas bearing for supporting a rotatable element in a contact-free manner, having the following features:

• a housing having an opening for receiving the rotatable element;
• and
• a plurality of multilayered sliding foils, wherein each multilayered sliding foil is arranged without overlapping an adjacent multilayered sliding foil on an inner side of the opening, and the individual layers of the multilayered sliding foils are all fixed to the housing with a first end portion, and the opposite second end portion forms a frictional contact with another layer of the multilayered sliding foil or with the housing;
• and
• wherein each layer of the multilayered sliding foils forms a circular segment in a radial section along a surface facing the rotatable element.

A method for manufacturing a gas bearing for supporting a rotatable element in a contact-free manner, comprising:

• providing a housing having an opening for receiving a rotatable element;
• arranging at least two sliding foils extending in an arc-shaped manner single- or multilayered between a first end portion and a second end portion on an inner side of the opening without adjacent sliding foils overlapping, wherein relative to the housing the first end portion is tangentially immovable and the second end portion provides a frictional contact with the housing or another layer of a multilayered sliding foil;
• and
• inserting the rotatable element into the opening so that the at least two sliding foils are disposed between the rotatable element and the housing.
