Definitions

  • the invention relates to a method for assembling and replacing large turbine housing parts.
  • Joints of turbine housing parts are usually fixed or positioned against each other with so-called guide, centering or fitting pieces, with wedges, fitting bolts, pins and similar parts.
  • the invention tries to avoid all these disadvantages. It is based on the task of creating a simple method for assembling and exchanging large turbine housing parts, in which no large machine tools have to be used and post-processing of the turbine housing parts is no longer necessary.
  • this is achieved in that a two-part guide wedge and a fitting bolt are used, the two parts of the guide wedge first being fitted in the wedge pockets of the housing parts to be connected, then a pilot hole is made in the parting plane of the pair of wedges, then the two halves of the Guide wedge are removed, fit over the pre-drilled hole and the final hole for the fitting bolt is now drilled, the guide wedges are then mounted and fixed by inserting the fitting bolt.
  • the advantages of the invention are, inter alia, that the inaccuracies between the independently produced wedge pockets are compensated for in a very simple and quick manner, no large machine tools are required, and the assembly and replacement of large divided turbine housings are easy to handle.
  • pilot bores are carried out as a prison bore with a hand drill and the wedge halves are positioned in front of the finished bore using a prison pin because this is the easiest and most precise way of drilling.
  • FIGS. 1 and 2 The invention is explained in more detail below using an exemplary embodiment and FIGS. 1 and 2.
  • the two housing parts 1 and 2 of a turbine have been manufactured at different locations, so that the manufacturing accuracy achieved is not sufficiently great.
  • the inaccuracies between the independently manufactured wedge pockets can be compensated for relatively easily by using a guide wedge 3 divided on the longitudinal side and a fitting bolt 4 which is cylindrical in this exemplary embodiment.
  • the two-part guide wedge 3 is first installed without a fitting bolt hole. There is a threaded hole in each half of the guide wedge 3 5 for a puller. The puller may be necessary when dismantling the guide wedge 3.
  • a Prison bore is carried out with the hand drill, for example ⁇ 10H7.
  • the next step is the removal of the two halves of the guide wedge 3. These are then positioned over a prison pin and clamped in a machine vise, where the final hole for the dowel pin 4, for example ⁇ 40H7, is made.
  • a conical fitting bolt connection can also be produced in another exemplary embodiment.
  • the guide wedge 3 is definitely installed and the finished fitting bolt 4, e.g. ⁇ 40k6, used.
