FIELD: mechanical engineering.
SUBSTANCE: device for adjustment of blades with variable angle of installation in turbomachine contains control ring installed with possibility to rotate around turbomachine body and connected with blades with variable installation angle using levers. Each lever has radial stud at its one end for connecting with control ring, and at the other its end - hole for mounting on square drive performed on the end of blade cylindrical pin. The blade pin is rotatably guided in cylindrical channel and has axis which is tilted relative to axis of lever radial stud. Hole in the lever has dimension in longitudinal direction of lever that exceeds dimension of square drive with which the lever interacts to form gap that varies according to square drive and mounting hole height. Gap height varies between the value which is sufficient to provide coupling engagement of mounting hole on square drive by means of lever moving in parallel to its radial stud axis and the value which actually equals to zero when the lever is placed on square drive.
EFFECT: invention makes possible to install lever by means of its engagement with control ring and blade pin while moving the lever in radial direction, and also to turn a blade precisely around its axis.
