  • Patent number: 8708648
    Abstract: A guide disc segment for a horizontally split turbomachine housing is provided. The guide disc segment includes a plurality of guide blades and an outer ring segment. The guide blades are fixed to the outer ring segment along an inner circumference. The outer ring segment can be rolled into or out of a guide blade carrier of the turbomachine housing. The outer ring segment has, along an outer circumference, a toothing into which a drive device engages. A tangential force can be applied to the outer ring segment by the toothing such that the guide disc segment can be driven during the rolling into or rolling out of the outer ring segment.

  • Patent number: 8641365
    Abstract: A rotor of a thermal turbomachine, particularly a gas turbine, is provided. The rotor includes a plurality of individual rotor components that are held together by a tie-bold and combined into a unit. The tie-bolt is supported by the assembly of the surrounding rotor components including the tie-bolt and the rotor disks. A hollow shaft which is made up of two tubular sections and a support wheel further support the rotor.

  • Patent number: 8545171
    Abstract: A rotor of a thermal fluid flow machine, especially a gas turbine, is provided. The rotor includes a plurality of rotor components that are held together by a common tie-bolt that extends through the center of the rotor components. The tie-bolt is fixed in at least one of the rotor components using at least one star spring that surrounds the tie-bolt in a circumferential direction.

  • Patent number: 8506239
    Abstract: A gas turbine is provided. The gas turbine includes at least one rotor, having rotor blades arranged on the periphery of rotor disks in a plurality of radial planes, and a tie-bolt extending along slots in the rotor disks and holding the rotor disks together as a unit. At least one annular spacer for fixing the position of the tie-bolt in relation to the center line of the rotor disks is also provided. The spacer includes through-openings that are arranged radially in relation to the tie-bolt or to its center line and that extend coaxially.

  • Patent number: 7828516
    Abstract: The invention relates to a device for support of an adjusting ring which encompasses at a distance a basically circular blade carrier, which adjusting ring is rotatable in the circumferential direction around a center axis which is identical with the blade carrier, in order to adjust radially extending blades of a ring of a turbo-engine, wherein a plurality of levers are provided between the blade carrier and the adjusting ring, which levers are distributed over the circumference, extend tangentially in each case, and which on their free ends have a rotatable roller in each case, which are rollable in the circumferential direction on the adjusting ring or on the blade carrier. According to the invention, the lever is tightly clamped on one side to disclose a wear-free and reliable device for support of an adjusting ring which encompasses at a distance a circular blade carrier.

  • Patent number: 7700907
    Abstract: The invention refers to a device for determining the angular position of a compressor stator blade, which is rotatable around its longitudinal axis and arranged in a compressor, with which is associated a measuring surface which rotates synchronously with it. For a reliable, simple and approximately error-free recording of the angular positions, the angular position of the compressor stator blade can be determined via the device in an automated manner. For this purpose, it has at least one mounting unit provided for aligned fastening of the device on the compressor, and at least one measuring and evaluating unit which comprises at least two distance sensors which each record a distance to the measuring surface which is rotatable from the reference position, as a result the angular position of the measuring surface, relative to the reference position depends upon the two recorded distances, is determined by the measuring and evaluating unit.
