THRUST SLIDING BEARING (OPTIONS) Russian patent published in 2021 - IPC F16C17/06 F16C32/06 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to the field of mechanical engineering, namely to thrust sliding bearings with self-aligning pads, and can be used in the designs of steam turbines, compressors, pumps and other rotary machines. In a thrust sliding bearing containing a housing with lubrication supply channels, thrust self-aligning pads, fixing elements and oil-removing scrapers installed in the inter-pad space, a hydrostatic pocket is made on the back of each pad, connected by an opening to the working surface of its pad, while a recess is made on the working surface in the central part of the pad, having an inclined section, in addition, an opening is provided in the scraper body connecting the lubrication supply channel in the bearing housing with a cavity in the upper part of the scraper, connected to the entrance to the working surface of the pad. In the second version of the bearing, two hydrostatic pockets are made on the back side of each pad, cross-connected by holes with the working surface of its pad: the first, in the direction of rotation, is connected to the working surface at the exit of the pad, and the second, in the direction of rotation, is connected to the working surface at the entrance to the pad, while on the working surface of the pad at the entrance to the pad and at the exit from the pad, recesses are made, each having an inclined section. In the third version of the bearing, a hydrostatic pocket connected by an opening to the working surface of its pad is made on the support surface of the bearing housing opposite each self-aligning pad. In the fourth variant, two hydrostatic pockets are made on the support surface of the bearing housing opposite each self-aligning pad, which are cross-connected by holes with the working surface of their pad.

EFFECT: giving the bearing higher damping properties, increasing its bearing capacity, eliminating axial deformation, as well as reducing the axial size of the self-aligning pad.
