Definitions

  • the invention relates to a paddle lock for the blading a turbine of the axial design with the features of the preamble of claim 1 and a method for producing a Scoop castle.
  • From DE-OS 30 28 701 is a paddle lock for a Turbine blading known in which the blades positively in an undercut, in the circumferential direction extending blade groove of the turbine rotor are used.
  • At the Turbine rotor circumference is at least one threading point provided, in which a form-fitting with the blade root Filler is inserted.
  • the filler is made by a fitting pressed tightly between the wall of the threading point and the filler is taken.
  • To increase the Contact pressure is the fitting slotted, with the drive of the fitting in the threading a wedge in the slit is pressed.
  • the pressing force acts on the known paddle lock on the Fitting piece or the wedge on the blade foot and thus on the Turbine runner itself. That can be too hard driven Wedge to a tension and curvature of the turbine runner to lead.
  • the hot-run behavior can be of the turbine rotor are negatively influenced, resulting in a Increase in the wave vibrations can lead.
  • the invention is based on the object, the generic Shovel lock to be designed so that no pressing force the turbine runner is exercised.
  • the filler is designed according to the invention Threading in the axial direction held such that it is not pressed against the blade root, but in the Keying supported in the threading in the turbine rotor.
  • the clamping force between the filler and the wedge acts no longer on the blade root, and the axial Contact force is no longer due to the blade groove passed.
  • the turbine runner experiences no axial Strain.
  • the insertion of the paddle lock can not a curvature of the turbine rotor during the Lead manufacturing process. A negative influence of one too tightly inserted paddle lock on the Warm-round behavior of the turbine rotor is eliminated.
  • each Blade of a blade groove including the tail blade finds the same blade groove dimensions and clamping conditions in front.
  • the clamping according to the invention of the keyed filler in the threading makes a production of the paddle lock according to claim 5 possible, in which the groove contour of the filler and generates the blade groove in a common clamping becomes. This results in the greatest possible accuracy of fit Filler and wedge.
  • the invention is generally applicable to turbines axial Design in overpressure or equal pressure design for steam turbines and process gas or residual gas turbines and in a special way for Bucket locks for shovel feet in Hammerkopf- or Double hammerhead construction.
  • a blade groove 2 with an undercut Bucket groove contour cut.
  • the blade groove 2 are circulating blades 3 inserted, consisting of a Airfoil 4 consist, which has a Schaufelrhomboid 5 in a blade root 6 passes. Instead of a rhomboid comes also a rectangle in question.
  • the blade feet 6 engage with a the Schaufelnutkontur corresponding contour in the blade groove. 2 one. This contour is in this embodiment as Double hammerhead trained.
  • At least one point along the blade groove 2 is a Threading 7 provided over the blades 3 in the Bucket groove 2 are introduced.
  • a filler. 8 used, the one of the Schaufelnutkontur corresponding contour has and with this contour in the blade root 6 of the Closing bucket engages.
  • the filler 8 is in the Einfädelstelle 7 by a wedge 9 wedged on the of Blade 3 opposite side of the filler 8 in the Threading 7 is driven.
  • the filling piece 8 receiving cross-section of the threading point 7 widens starting from the blade groove 2 conical.
  • the side walls of the threading point 7 with the longitudinal axis of the blade 3 each have an angle ⁇ 1 , ⁇ 2 .
  • This angle results from the angle of the vane roboid.
  • the angles can vary from case to case, even among each other in the paddle lock. Accordingly, the filler 8 has two tapered, the threading 7 adapted side surfaces.
  • the voltage applied to the back of the filler 8 wedge 9 is so far into the threading 7 driven that between the Leading edge of the wedge 9 and the bottom of the threading 7 a Distance remains.
  • the manufacture of the blade lock forming parts takes place in the following way.
  • the turbine rotor 1 is a the later Schaufelnut 2 forming Vorwindnut 2 'screwed in and the Threading 7 milled.
  • the threading 7 is a Blank 8 'for the filler 8 and a wedge blank 9' inserted and by driving the wedge blank 9 'in the threading 7th braced.
  • the blank 8 'for the filler 8 is up on the Blade groove contour preprocessed.
  • the wedge blank 9 ' needed an excess length or a threaded hole, so he after the Completion of the paddle lock can be pulled again.
