Description

Die Erfindung betrifft eine Doppelmantelturbine, deren Außengehäuse aus Blech geschweißt ist und deren Innengehäuse zentrisch wärmebeweglich auf waagerechten Flächen des Außengehäuses aufliegt.The invention relates to a double-shell turbine, the outer casing of which is welded from sheet metal and whose inner housing rests centrally on horizontal surfaces of the outer housing so that it can move with heat.

Das blecherne Außengehäuse neigt unter dem Gewicht des Innengehäuses, das bei großen. Turbinen etwa 100 t erreicht, leicht dazu, sich zu verformen, und zwar um so mehr, je größer die horizontalen und die vertikalen Abstände der Flächen, an denen das Innengehäuse auf dem Außengehäuse-Unterteil aufliegt, von den Flächen, mit denen das Außengehäuse auf dem Fundament ruht, sind.The tinny outer casing tends to take the weight of the inner casing, which is the case with large. Turbines reached about 100 t, easily to deform, and the more so the larger the horizontal and the vertical distances between the surfaces on which the inner housing rests on the outer housing lower part, of the surfaces with which the outer housing rests on the foundation.

Das soll die Erfindung vermeiden. Sie beruht auf dem Gedanken, jene Abstände möglichst gering zu halten, also die durch das Gewicht des Innengehäuses erzeugten Kräfte auf dem kürzesten Wege ins Fundament zu leiten, und auf dem bekannten Wissen, daß um guter Zentrierung willen die Flächen, auf denen das Innengehäuse aufliegt, möglichst in der Achsebene liegen sollen.This is to avoid the invention. It is based on the idea of keeping those distances as small as possible hold, i.e. the forces generated by the weight of the inner housing on the shortest route to the foundation to direct, and on the known knowledge that for the sake of good centering the surfaces on which the inner housing rests, should be in the axial plane if possible.

Die Erfindung besteht darin·, daß das Außengehäuse in an sich bekannter Weise in achsnaher Ebene auf dem Fundament aufruht und daß seine Flächen, auf denen das Innengehäuse aufliegt, lotrecht über denjenigen Flächen, mit denen das Außengehäuse auf dem Fundament ruht, angeordnet und von ihnen nur durch die Wandstärke des Außengehäuses getrennt sind.The invention consists in that the outer housing rests in a manner known per se in a plane close to the axis on the foundation and that its surfaces on which the inner housing rests, perpendicularly over those surfaces with which the outer housing on the Foundation rests, arranged and separated from them only by the wall thickness of the outer housing.

Dadurch wird erreicht, daß das Gewicht des Innengehäuses auf dem kürzesten Wege in das Fundament eingeleitet wird, wobei etwaige Bewegung zwischen den aufliegenden Flächen vernachlässigt werden kann, zumal nur geringe Temperaturunterschiede zwischen der Außenatmosphär*
Stelle auftreten.This ensures that the weight of the inner housing is introduced into the foundation in the shortest possible way, whereby any movement between the surfaces on it can be neglected, especially since only small temperature differences between the outside atmosphere *
Occur.

Die Erfindung kann weiter ausgestattet werden dadurch, daß das Außengehäuse um die eben beschriebenen Flächen herum Taschen bildet, in die die Tragarme des Innengehäuses hineinragen; dies hat den Vorteil, daß der Durchmesser des Außengehäuses klein gehalten werden kann.The invention can be further equipped in that the outer housing around the just described Forms pockets around surfaces into which the support arms of the inner housing protrude; this has the The advantage that the diameter of the outer housing can be kept small.

In Fig. 1 ist der Tragarm 14 mit dem Innengehäuse fest verbunden; das geschweißte Außenge'häuse21 liegt auf dem Turbinenfundament 13 auf; der Tragarm 14 ragt in die Tasche 16 hinein. In Fig. 2 sind zwei Tragarme 14 und 15 gezeigt, die in den Taschen und 17 des Außengehäuses 21 befestigt sind.In Fig. 1, the support arm 14 is firmly connected to the inner housing; the welded outer housing21 rests on the turbine foundation 13; the support arm 14 protrudes into the pocket 16. In Fig. 2 are two support arms 14 and 15 are shown which are fastened in the pockets 16 and 17 of the outer housing 21.
