Definitions

  • the present invention relates to the attachment of a turbine housing to foundation crossbars and to the bearing housing.
  • the aforementioned object is achieved according to the invention in that at least one support rib is provided on the turbine housing, which is rigidly connected to the foundation cross bar in the axial direction via a pendulum support and a holder, and in that a claw of the turbine housing is mounted so that it can move axially on a bearing surface of the bearing housing .
  • these are axially adjustable via eccentric bushes.
  • This training enables a fine adjustment without play.
  • 1, 1 denotes a housing of a turbine, the shaft 2 of which is mounted in a bearing housing 3.
  • At least one support rib 4 is arranged on the lower part of the turbine housing 1, while a claw 5 is provided on the upper part, which is axially movably mounted on a bearing surface 6 of the bearing housing 3.
  • the bearing housing 3 is mounted on a foundation crossbar 9 via adjustment bolts 7 and a foundation plate 8, the adjustment bolts 7 serving for height adjustment.
  • a pendulum support 10 is arranged, which is attached to a bracket 11.
  • the bracket 11 is in turn fixed by means of retaining bolts 12, which penetrate the foundation cross bar 9, by means of adjusting screws 13 for coarse axial adjustment.
  • the pendulum support 10 With the pendulum support 10 shown in FIG. 2, the distance between the turbine housing 1 and the foundation crossbeam 9 can be fine-tuned according to the eccentric principle.
  • the pendulum support 10 has two eccentric bushes 14, 14 ', which have a spindle 15 and one Nut 16 are connected to each other with a cylindrical pin 17.
  • the pendulum support 10 itself has on its bearing surfaces on the spindle 15 konisehe ends 19, 19 ', whereby only a part D rests on the spindle 15, and thus greater mobility of the pendulum support 10 is achieved.
  • pressure plates 20 are arranged on the foundation crossbar 9, on which set screws 21 with spherically shaped engagement surfaces 22 rest.
  • the set screws 21 are rotatably arranged in threaded bores 23 of the holder 11, so that a rough adjustment of the fixed point can thus be carried out.
  • the holder 11 is fixed in its position by means of the retaining bolts 12 and nuts 24.
