Definitions
- the invention relates to a method and an apparatus for determining the mutual distance between two surfaces of two components which face one another to form a gap, in particular for measuring the gap width when assembling the compressor diffuser and combustion chamber of a gas turbine.
- the invention has for its object to provide a method and an apparatus of the type mentioned, which allow the measurement of a not directly accessible gap in a simple manner.
- the distance to a second reference point specified at the second component and the angle between the measuring straight line defined by the two reference points and a measuring straight line intersecting in the first reference point result from a first reference point fixed relative to a first component, is measured with respect to the first component orientation-oriented reference and is compared with at least one predetermined distance / angle reference value pair.
- a device suitable for carrying out the method is characterized by a stationary base part which can be applied to one of the components and a measuring rod which is rotatable about an axis on the base part and displaceably mounted radially relative to the axis against the second component.
- the base part preferably has an angle division for determining the angle of inclination and a length graduation for determining the longitudinal displacement of the measuring rod.
- the measuring rod can be mounted so as to be longitudinally displaceable in a guide rail rotatably fixed to the base part, wherein the length graduation can be arranged on the measuring rod and / or on the guide rail.
- the measuring rod for reading the inclination angle and the longitudinal displacement of the base part is preferably fixable via a seated on the axis locking nut.
- Fig. 1 shows the principle of the inventive measuring method, used in the assembly of a gas turbine
- Fig. 2 is an oblique view of a measuring device.
- FIG. 1 shows a cross section through an arrangement 10 of two components 12, 14 with two surfaces 16, 18, which face each other parallel to form a gap 20 of a width C.
- the gap 20 is thus at a distance from an outer surface of the arrangement 10 in that it is accessible only under difficult conditions and therefore the gap width b can no longer be easily determined from the outer surface of the arrangement 10 with conventional measuring devices, such as with a slide gauge.
- the arrangement 10 shown by way of example in FIG. 1 relates to a gas turbine of the GT13 E2 type from the Applicant's home.
- Component 12 corresponds to the inner combustion chamber jacket, component 14 to the compressor diffuser.
- the two opposing surfaces 16, 18 are concentric with a turbine axis arranged conical annular surfaces.
- the adjustment of the concentricity of the compressor diffuser and the combustion chamber during assembly of the gas turbine via pressure pins 22 which are arranged distributed over the circumference of the compressor-diffuser, and over the pressure pin 22 resting adjusting segments 24, which extend beyond the circumference of the combustion chamber jacket are arranged distributed.
- FIG. 2 protractor 26 consists essentially of a base body 28 with a projecting from a support surface 30 down stop web 32 and upstanding from the base 28, at right angles to the support surface 30 and the stop bar 32 stationary measuring plate 34 to which a guide rail 36th is rotatably fixed to a perpendicular projecting from the measuring plate 34 axle 38.
- a measuring rod 40 is mounted longitudinally displaceable.
- the measuring rod 40 is equipped with a slot 42 extending in the longitudinal direction of the measuring rod 40.
- the elongated hole 42 passing through, threaded axle 38 is a locking nut 44 is placed, with which the guide rail 36 can be fixed to the measuring rod 40 to the measuring plate 34.
- the measuring plate is equipped with an angle division 35.
- the measuring rod 40 is provided with a Popemass republic 41 for easy reading of the mutual distance D of the two reference points P1, P2.
- the protractor 26 shown in FIG. 2 makes it possible to determine the gap width C over the entire circumference of the gas turbine when the setting segments 24 are used completely.
