Description

Kühlvorrichtung, insbesondere für die abzudichtenden Stellen von umlaufenden Wellen Die Erfindung betrifft eine Kühlvorrichtung, insbesondere für umlaufende Wellen, und besteht darin, daß zwischen der Welle und einer dicht an ihr anliegenden, sie einhüllenden, als Körper für sich ausgebildeten und mit der Welle umlaufenden Büchse, welche zugleich die Lagerfläche für die Welle bildet, mindestens ein Hohlraum vorgesehen ist, welcher für den Durchlauf eines die Kühlung der Welle bewirkenden Mittels eingerichtet ist. Der Hohlraum kann durch kammförmige Ausbildung der Welle in mehrere gegebenenfalls untereinander in Verbindung stehende Teilräume unterteilt sein.Cooling device, in particular for the areas to be sealed off Shafts The invention relates to a cooling device, in particular for rotating Waves, and consists in the fact that between the wave and a enveloping them, designed as a body for themselves and revolving with the wave Bush, which at the same time forms the bearing surface for the shaft, at least one cavity is provided, which causes the cooling of the shaft for the passage of a Is set up by means. The cavity can be formed by a comb-shaped design of the shaft subdivided into several sub-spaces that may be connected to one another be.

Ein Ausführungsbeispiel des Erfindungsgegenstandes ist auf der Zeichnung an Hand einer eine heiße Flüssigkeit fördernden Pumpe schematisch dargestellt.An embodiment of the subject matter of the invention is shown in the drawing shown schematically on the basis of a pump conveying a hot liquid.

Auf der umlaufenden Welle i ist das Laufrad 2 befestigt, welches im Gehäuse 3 der Pumpe umläuft. Ein Ringraum q. der Stopfbüchse 5 steht durch einen Kanal 6 mit einer Kühhnittelleitung in Verbindung. Die Brille 7 der Stopfbüchse enthält außer einer Vorstopfbüchse 8, welche durch eine Überwurfmutter g abgeschlossen ist, einen Ringraum io, welcher mit der Ableitung ii für das Kühlinittel in Verbindung steht. Über die Welle i ist eine als Körper für sich ausgebildete Büchse 12 gezogen. Durch die Kämme 13 und 14 der Pumpenwelle werden Hohlräume 15, 16 und 17 gebildet.On the rotating shaft i, the impeller 2 is attached, which in Housing 3 of the pump rotates. An annulus q. the stuffing box 5 is through a Channel 6 in connection with a refrigerant line. The gland 7 of the stuffing box contains apart from a stuffing box 8, which is closed by a union nut g is, an annular space io, which is connected to the discharge line ii for the cooling medium stands. A sleeve 12 designed as a body is drawn over the shaft i. Cavities 15, 16 and 17 are formed by the combs 13 and 14 of the pump shaft.

Das durch den Kanal 6 eingeführte Kühlmittel strömt aus dem Ringraum 4 durch die Öffnung 18, die Laterne ig und die Öffnung 2o in den Hohlraum 15, von dort durch die Öffnungen 21 in den Hohlraum 16 und aus dem letzteren zum Teil durch Öffnungen 22 in den Hohlraum 17, zum Teil durch den Ringraum io in die Ableitung ii. Insoweit das durch den Spalt z3 eindringende Wasser bis zur Laterne ig gelangt, wird es durch das Kühlmittel aufgenommen.The coolant introduced through the channel 6 flows out of the annular space 4 through the opening 18, the lantern ig and the opening 2o into the cavity 15, from there through the openings 21 into the cavity 16 and out of the latter in part Openings 22 in the cavity 17, partly through the annular space io in the discharge line ii. Insofar as the water penetrating through the gap z3 reaches the lantern ig, it is absorbed by the coolant.

Durch die Anordnung eines oder mehrerer Hohlräume zwischen der Welle und der sie umschließenden Büchse wird die Temperatur der Welle derart beeinflußt, daß sie bei Stopfbüchsen für die Abdichtung und bei Lagern für die Schmierung am günstigsten ist. .By arranging one or more cavities between the shaft and the sleeve surrounding it, the temperature of the shaft is influenced in such a way that that they are used in stuffing boxes for sealing and in bearings for lubrication is cheapest. .
