RADIAL SLIDING SUPPORT Russian patent published in 1998 - IPC

FIELD: mechanical engineering. SUBSTANCE: radial sliding support has fixed inner cylindrical bushing installed in machine stator and movable outer cylindrical bushing connected with rotor. Working clearance to be filled with lubricant is provided between bushings. Channels with throttling members to feed lubricant into working clearance are made in inner part of fixed bushing. Flexible support device is connected to fixed bushing from outer side. Support device consists of two similar circular diaphragms made of flexible material, connected with bushing by side edges and arranged symmetrically relative to plane passing through middle of support square to its axis. Diaphragms are provided with holes to let lubricant pass to working clearance of support. Ring made of antifriction material is fitted on fixed bushing to prevent contact of support surfaces of bushing and diaphragm with no lubricant in support, i.e. at idling. EFFECT: enlarged operating capabilities. 2 cl, 1 dwg
