  • Combined sealing and balancing arrangement for a turbine disc
    Patent number: 9593581
    Abstract: A turbine disc for a turbine is provided with a first protrusion and a second protrusion. The first protrusion and the second protrusion are formed in such a way that a balancing weight is coupleable between the first protrusion and the second protrusion. The first protrusion has a sealing section that is capable of sealing a fluid passage between the turbine disc and a further turbine part of the turbine.

  • Method and tool for producing a coupling with a flat bottom and central protrusion
    Patent number: 9518612
    Abstract: A curvic coupling for rotational coupling is provided herein. The curvic coupling includes: plural teeth arranged in a circle and protruding from a circle plane extending in a radial direction and a circumferential direction, wherein a side surface of a tooth of the plural teeth is opposite to a side surface of another tooth of the plural teeth, and wherein the tooth is adjacent to the other tooth and is separated from the other tooth by a separating surface. The separating surface includes a flat surface lying in the circle plane, wherein the separating surface includes a central protrusion between the side surface of the tooth and the side surface of the other tooth, and wherein the protrusion protrudes from the circle plane.
