FIELD: mechanical engineering; high-speed mechanisms. SUBSTANCE: gas-dynamic thrust bearing includes supporting and load-bearing plates made in form of washers manufactured from elastic material. Supporting plate has cuts in form of part of sector bent towards thrust disk of lug and located over circle of bearing at reduction of length in way from center to periphery of plate and in direction of rotation in bearing; as length of lug decreases, angle of its bend increases. Bearing is additionally provided with intermediate plate made from foil and provided with holes registered with those in load-bearing plate; load-bearing plate is provided with tabs. Supporting, intermediate and load-bearing plates are aligned and interconnected by means of radial cuts. As a result, lubricating layer of required shape is obtained and air is freely admitted to beginning of tab. EFFECT: enhanced efficiency. 2 cl, 5 dwg |
