FIELD: motors and pumps.
SUBSTANCE: guiding unit for blade with adjustable setting angle for gas turbine motor compressor installation. Blades include rotary axis being formed by cylindrical axial root. The root is installed inside cylindrical casing support. The blade root is directed by guiding unit to move around casing support by means of two stoppers with tapered rollers. Roller axes are perpendicular to the blade rotation axis. The first stopper rests upon one blade end with one of the stopper rings. The other ring rests upon circular ledge of casing support. The other roller stopper rests upon the circular ledge of casing support with one of the rings. The other ring of stopper rests upon contraction nut screwed on axial root of the blade.
EFFECT: improved reliability of guiding unit and reduction of rolling elements wear-out.
