FIELD: engines and pumps.
SUBSTANCE: device for driving the turbine blades with variable installation angle incorporates drive ring and set of drive levers. Every drive metal sheet lever has the first end with drive hole t arranged on the blade outer journal drive end and the second end articulated to the drive ring. The aforesaid drive hole contains the first drive section to get in contact with the said blade outer journal drive section and to define the first contact area, i.e. "drive lever/outer journal". Note here that there is a clearance between the blade outer journal drive section and the drive lever drive hole directed perpendicular to the said first contact area. The turn of the drive lever first end on the blade drive section is effected via the clearance taking-up sheet resting upon drive lever lateral side via the second contact area, i.e. "drive lever/clearance taking-up sheet". The aforesaid drive lever lateral side is, in fact, perpendicular to the drive lever first end, while the second contact area is, in fact, parallel to the first contact area intended for pressing the blade drive lever to its first end in the first contact area.
EFFECT: simpler design of drive device and higher accuracy of arrangement of drive lever on turbine blade with variable installation angle.
