Vane actuating arm for a gas turbine, turbomachine having the vane actuating arm, and method for mounting a vane actuating arm for a turbomachine

Abstract

Avane actuating arm (10) for a turbomachine, the vane actuating arm (10) including two legs (12) which are pivotable relative to each between at least one open position and a closed position and form a clamping device having at least one clamping surface (14) on each of the legs (12). In the closed position, a vane stem (20) provided for varying the pitch of a stator vane of the turbomachine can be frictionally held between the two legs (12) via the two clamping surfaces (14), forming a clamping connection (16). Each of the legs (12) has an opening (50), the openings (50) overlapping each other in the closed position such that a through-bolt connectable to an actuating element of the turbomachine for controlling an angular position of the vane stem (20) can be passed through the openings (50).
