Embodiment Construction

[0021] The figures are each a significantly simplified illustration, in which only the main components necessary for the description of the invention are shown.

[0022] Identical or functionally identical components are provided with the same reference symbols in relation to the figures.

[0023] figure 1 The lower part of the two-part holding body 2 for the guide vane carrier 1 is shown. The holding body 2 is generally an integral part of the turbine housing, but can also be formed from a separate component.

[0024] The holding body 2 has a bead 12 on its inner peripheral surface 11 . Recesses 13 are formed in the cam at both open ends of the holding body 2 . In the assembled state, the notch is used to provide a smooth abutment surface for the adjustment screw 10 of the height adjustment element 4 (see image 3 and 4). Furthermore, the holding body 2 has a notch 8 centrally in the collar 12 in the circumferential direction. This notch 8 serves to accommodate the fast...

Abstract

The invention relates to a guide vane support arrangement for a turbine, comprising a guide vane support (1) and a carriage (2) for the guide vane support. A fixing element (3) is disposed between the guide vane support (1) and the carriage (2) in such a way that the guide vane support (1) can swivel inside the carriage (2) about the fixing element (3). The invention also relates to a method for adjusting the radial play between the guide vane support (1) and the carriage (2).

Description

technical field [0001] The invention relates to a guide vane carrier for a turbomachine and to a method for adjusting a radial play between the guide vane carrier and a holder of the guide vane carrier. Background technique [0002] Guide vane holders are currently installed in almost all multistage overpressure steam turbines. The main task of the guide vane holder is to accommodate the guide vanes. The guide vane carrier is guided axially centrally in the guide element. Side fixing is mostly achieved with vertical screws. The axial support is fixed in the housing by means of a groove-to-slip connection. Here, the design must be chosen such that the guide vane carrier can expand unrestrictedly under the influence of heat without changing the position of the axial center. In order to adjust the position of the axial center of the guide vane carrier, various adjustment elements are used which, in addition to having to bear the weight, also have to absorb the torque caused...
