Monograph by M. "Science", 1975. , p. 48. The monograph is devoted to the study of antifriction materials of working elements of bearings with gas lubrication and is one of the first in this direction. A description of the working conditions is given, and the requirements for the materials of the bearing elements with gas lubrication are systematized. The results of the study of the conditions for the rise and landing of the spike of the gas-dynamic bearing under normal and reduced environmental pressure. are presented. The results of studies of materials on the IUGP-2 end friction machine in relation to the operating conditions of thrust gas-dynamic bearings, as well as the results of studies of materials of hinge devices for self-aligning elements of bearings with gas lubrication . The monograph is designed for scientific and engineering workers engaged in the research and design of units and machines on supports with gas lubrication . Table. 4, il. 17, Bibl. 18 titles.
