Description
Die Erfindung betrifft ein in einer oder in mehreren Achsebenen geteiltes Axialturbinengehäuse, dessen Sektoren auf mindestens einem Teil der Gehäuselänge durch Ringe umschlossen und zusammengepreßt sind, wobei die Ringe in einer oder in mehreren Achsebenen geteilt sind und Spannmittel die Segmente jeden Ringes und daher die Sektoren des Gehäuses zusammenpressen, nach Patentanmeldung L 25741 Ia/14c.The invention relates to an axial turbine housing which is divided in one or more axial planes Sectors are enclosed and pressed together by rings on at least part of the length of the housing, wherein the rings are divided into one or more axial planes and clamping means are divided into the segments Press each ring and therefore the sectors of the housing together, according to patent application L 25741 Ia / 14c.
Die Gehäusesektoren neigen, besonders bei großem Abstand der Ringe, dazu, zwischen den Ringen an den Teilfugen auseinanderzuklaffen, so daß dort Treibmittel durch die Fugen dringt. Diesen Nachteil soll die Erfindung beheben.The housing sectors tend, especially if the rings are far apart, to come between the rings to gape apart the butt joints so that propellant penetrates through the joints. This disadvantage is intended to remedy the invention.
Die Erfindung besteht darin, daß die .Gehäusesektoren zur Abdichtung und zu ihrer gegenseitigen Fixierung in an sich bekannter Weise an den Flächen, mit denen sie aneinander anliegen, mit achsparallelen Nuten und Federn versehen sind, wobei entweder die eine von je zwei aneinanderliegenden Flächen mit einer Nut, und die andere mit einer Feder versehen ist oder beide Flächen mit je einer Nut versehen sind und eine lose Feder in die beiden Nuten eingelegt ist.The invention consists in that the housing sectors for sealing and for their mutual fixation in a known manner on the surfaces, with which they rest against each other, are provided with axially parallel grooves and tongues, either the one of every two adjacent surfaces is provided with a groove, and the other with a tongue or both surfaces are each provided with a groove and a loose tongue is inserted into the two grooves.
Der Querschnitt von Nut und Feder ist vorzugsweise rechteckig; er kann jedoch auch in bekannter Weise rund oder teilweise gerundet sein.The cross-section of the tongue and groove is preferably rectangular; however, he can also be known in Way round or partially rounded.
In der Zeichnung sind zwei Ausführungsbeispiele dargestellt.Two exemplary embodiments are shown in the drawing.
Gemäß der Fig. 1 liegt eine Feder 10 einer Gehäusehälfte 11 in einer Nut 12 einer Gehäusehälfte 13. Der Treibmitteldruck im Gehäuseinnenraum 14 bewirkt, daß sich mindestens die Kante 15 der Feder 10 gegen die Fläche 17 der Gehäusehälfte 13 und die Kante 16 der Gehäusehälfte 13 gegen die Fläche 20 der Feder 10 legen, wodurch Linienberührung und somit einwandfreie Abdichtung gegeben ist. Die Teilfuge wird durch die Flächen 17, 18, 21, 23 und 25 der Gehäusehälfte 11 und die Flächen 19, 20, 22, 24 und 26 der Gehäusehälfte 13 gebildet.According to FIG. 1, a tongue 10 of a housing half 11 lies in a groove 12 of a housing half 13. The propellant pressure in the housing interior 14 causes at least the edge 15 of the spring 10 against the surface 17 of the housing half 13 and the edge 16 of the housing half 13 against the surface 20 the spring 10, whereby line contact and thus perfect sealing is given. The parting line is through the surfaces 17, 18, 21, 23 and 25 of the housing half 11 and the surfaces 19, 20, 22, 24 and 26 of the housing half 13 is formed.
Ähnlich verhält sich die Dichtung im Gebiet der Teilfuge gemäß der Fig. 2. Die obere und die untere
Gehäusehälfte 27 und 28 enthalten je eine Längsnut 29 bzw. 30. In diesen beiden Längsnuten 29, 30 liegt
eine Feder 31. Die Teilfuge wird durch die Flächen 32, 34, 36, 37 und 38 der Gehäusehälfte 27, die
In einer oder in mehreren Achsebenen
geteiltes AxialturbinengehäuseThe seal behaves similarly in the area of the parting line according to FIG. 2. The upper and the lower housing halves 27 and 28 each contain a longitudinal groove 29 and 30, respectively Areas 32, 34, 36, 37 and 38 of the housing half 27, which in one or more axial planes
split axial turbine housing
