ROW OF BLADES OF STRAIGHTENING DEVICE DRIVEN WITH ROTARY RING OF AUTOMATIC CENTRING, COMPRESSOR EQUIPPED WITH SAID ROW OF BLADES AND GAS-TURBINE MOTOR CONTAINING THIS COMPRESSOR

摘要

FIELD: machine building. ^ SUBSTANCE: jacket contains stationary coaxial circular rail projecting from external surface of this jacket. Also, at least three movable parts spaced one from another in circumferential direction can travel along this rail. Each movable part is connected with the driven ring by means of a radial guiding structure. For each movable part the radial guiding structure contains an element in form of a rod installed in radial direction into an orifice made in the said ring. The rod-shaped element is secured on the movable part. Another invention of the group refers to a compressor equipped with at least one above said row of the blades of the straightening device with alternate angles of assembly. One more invention refers to the gas-turbine motor incorporating the said compressor. ^ EFFECT: upgraded quality of centring driven ring relative to jacket under effects of high temperature. ^ 16 cl, 8 dwg
