TAB-TYPE GAS DYNAMIC BEARING Russian patent published in 1999 - IPC

FIELD: mechanical engineering; sliding bearing with liquid and gaseous lubrication for axis and radial support of rotors of high-speed turbo-machines, for example, turbo-coolers, turbo-expanders, turbo-compressors, turbo-superchargers, turbo-generators and turbo-pumps. SUBSTANCE: tab-type gas-dynamic bearing includes plate with bearing members secured on it, flexible tabs overlapping one another and secured on bearing members at one side. Edge of tab rests on adjacent tab and lower part of tab rests on spring which is made in form of bent sheet whose edges rest on plate; it is secured on plate in area of overlapping of tabs for self-setting. Height of bent of springs may be constant in their length or may increase from inner radius of plate to its outer radius for axial bearing; width of spring reduces from inner radius of plate to its outer radius . EFFECT: increased service life of bearing due to profile of tab in form of arc of small curvature; increased load at start; reduced axial play in axial bearing; increased carrying capacity of bearing; facilitated manufacture; enhanced stability of bearing properties. 3 cl, 8 dwg
