FIELD: power engineering.
SUBSTANCE: invention relates to rotor blade of wind-driven power plant. Rotary blade (108) of wind-driven power plant by means of rotary joint (1) is connected to hub of wind-driven power plant. Rotary joint is made in form of sliding bearing assembly containing inner ring (3, 3', 3'') with a number of first sliding surfaces (11a, b, c), outer ring (5, 5', 5'') with a number of second sliding surfaces (13a, b, c), which are respectively related to one of the first sliding surfaces as sliding components. Slide bearing assembly is made in form of dry running sliding bearing, wherein outer ring (5) has one, several or all of number of sliding surfaces (13a–c) of fibrous composite material and is made of at least two parts, radial sliding surface and first sliding surface are formed on first part, while second axial sliding surface is formed on at least one second part (5b), at that first part (5a) is made integral on rotor blade (108).
EFFECT: invention is aimed at load reduction.
