Abstract
Abstract A gas-lubricated bearing is provided with a bushing mounted in a housing by means of elastic rings mounted on ends. The surface of the hole in which the bushing is mounted, the outer surface of the bushing and the side surfaces of elastic rings form a chamber, in which throttling elements are located between the outlets of holes for feeding gas into it, and inlets of holes in the bushing on the periphery of the bushing. Elastic baffles are mounted along the longitudinal elements of the cylinder of the bushing.
