Abstract
The present invention relates to an adjustment assembly for the adjustment of adjustable blades or vanes of a turbomachine, having an adjustment ring for coupling to the adjustable blades or vanes of a blade or vane ring and having an adjusting mechanism, which has a coupling rod for coupling to a further blade or vane ring as well as a lever and a push rod, wherein the lever is rotatably mounted at a pivot and has a load arm as well as a force arm, wherein the load arm of the lever is coupled to the push rod and its force arm is coupled to the coupling rod, on different sides of the lever, so that an offset of the coupling rod via the lever and the push rod is converted to a rotation of the adjustment ring around the ring axis thereof.
Claims15
An adjustment assembly for the adjustment of adjustable blades or vanes of a turbomachine, comprising:
- an adjustment ring for coupling to the adjustable blades or vanes of a blade or vane ring and
- an adjusting mechanism, which has a coupling rod for coupling to a further blade or vane ring as well as a lever and a push rod, the push rod lying in a plane that is spanned by the lever, the coupling rod lying in the plane that is spanned by the lever,
- wherein the lever is rotatably mounted at a pivot and has a load arm as well as a force arm,
- wherein the load arm of the lever is coupled to the push rod and its force arm is coupled to the coupling rod, so that an offset of the coupling rod via the lever and the push rod is converted to a rotation of the adjustment ring around the ring axis thereof,
- and wherein the coupling rod and the push rod are arranged on different sides of the lever.
