HIGH-SPEED THRUST BEARING Russian patent published in 2007 - IPC F16C17/08 F16C27/08 

FIELD: mechanical engineering.

SUBSTANCE: proposed high-speed thrust bearing contains rotor with pivot, radial segment bearing, multilayer insert consisting of foamed vibration-damping material and antifriction material. Leading and trailing edges of segments are parallel to each other. Segments are divided by lubricating grooves whose axes are arranged tangentially to circumference concentric to circumference forming inner edges of segments to circumference forming outer edges of segments. High-speed thrust bearing can be made split, division planes passing through axial lines of lubricating grooves arranged diametrically opposite to each other, number of segments in plant can be, for instance, even.

EFFECT: improved serviceability, reliability and increased service life of trust (axial) sliding bearing at high speeds of rotor.
