ANTIWEAR DEVICE FOR GUIDE ROLLER OF BLADE WITH VARIABLE SETTING ANGLE IN COMPRESSOR OF GAS-TURBINE ENGINE, COMPRESSOR OF GAS-TURBINE ENGINE AND GAS-TURBINE ENGINE

摘要

FIELD: engines and pumps.;SUBSTANCE: blade with variable setting angle for compressor of gas-turbine engine includes sleeve installed with possibility of rotation around guide roller of blade and intended for installation into housing of turbo machine. Connection between sleeve and guide roller is performed by a pair of nickel graphite/titanium; at that, guide roller consists of material on the basis of titanium, and sleeve is made from material on the basis of nickel and graphite. Sleeve has been made by agglomeration of powder on the basis of nickel and graphite. Other inventions of the group refer to gas-turbine engine and its compressor including the above blades with variable setting angle.;EFFECT: higher wear resistance of friction pair and lower friction coefficient.;4 cl, 2 dwg
