SUPPORT PLAIN BEARING Russian patent published in 2019 - IPC F16C17/03 F16C25/04 

FIELD: machine building.

SUBSTANCE: invention relates to machine building, particularly, to plain bearings with self-adjusting cushions, and can be used, for example, in high-speed centrifugal compressors. Support sliding bearing includes housing (1) with internal cylindrical surface (2) and self-adjusting cushions (3–7) arranged in it, resting on elastic elements in the form of plate springs (8). Plate springs (8) are installed on paired support platforms (15) on surface (2), between which there are grooves (16), providing possibility of deflection of plate springs (8). Pair support platforms (15), on which plate springs (8) are installed, which are located under unloaded cushions, are made at a smaller distance from longitudinal axis of surface (2), in comparison with paired support platforms (15), on which plate springs located under loaded cushions are installed.

EFFECT: increased reliability and durability of operation of the plain bearing at dynamic loads.
