SLIDING BEARING Russian patent published in 2008 - IPC F16C17/02 F16C33/10 

FIELD: engineering industry; sliding bearings.

SUBSTANCE: destined to be used in the high-speed turbine pumps, centrifugal pumps and axial vane-type pumps, generally, in the pumps using pumped fluid for the bearings lubrication, e.g., in the liquid-fuel rocket engines' gas turbine-pump systems. Sliding bearing being lubricated with the fluid being pumped includes shaft and female bushing with the area covered by the V-grooves arranged uniformly along the circumference, their depth decreasing in the shaft rotation direction. On the bushing internal surface there is a smooth cylindrical area, which builds with the shaft a gap being equal or lesser than that between the shaft and the V-grooved area. V-grooved area is made so that it opens to the bushing face, which is turned into the cavity the lubricant is supplied from. EFFECT: increase of the pumps' life time and efficiency; design simplification.
