  • VANE ACTUATING ARM FOR A GAS TURBINE, TURBOMACHINE HAVING THE VANE ACTUATING ARM, AND METHOD FOR MOUNTING A VANE ACTUATING ARM FOR A TURBOMACHINE
    Publication number: 20250092795
    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).

  • Lever for adjusting an adjustable vane
    Patent number: 11873722
    Abstract: The present invention relates to a lever for adjusting an adjustable vane of a turbomachine, wherein the lever has a fulcrum for the rotatable mounting of the lever about an axis of rotation, a first load arm with a first adjusting connection point for at least indirect connection to an adjustable vane and a first force arm with a first actuating connection point for connection to an adjusting device, wherein the lever further has a first strut, which connects the first adjusting connection point and the first actuating connection point to each other and thereby extends in an arc-shaped manner about the axis of rotation.
