KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die zur Erzeugung von künstlichem Luftzug' bei Schiffskesseln dienenden Ventilatoren, welche in Gestalt von Flügelrädern u. dergl. in den Schornsteinen untergebracht sind, leiden vor allem bei gröfseren Dampfern und hohen Schornsteinen und mithin entsprechend langen Wellen an dem Uebelstand, dafs mehrere Führungslager zwischen dem unteren und dem' oberen Lager für die Welle nöthig sind.The one used to generate artificial drafts' fans used in ship boilers, which are in the form of impellers and the like in the Chimneys are housed, suffer especially with larger steamers and high ones Chimneys and consequently correspondingly long waves at the disadvantage that several Guide bearings between the lower and the 'upper bearing for the shaft are necessary.
Wenn beim Betrieb der Kessel die Ventilatoreinrichtung längere Zeit nicht im Gebrauch ist, verrufsen die Führungslager; auch tritt ein vollständiges Festbrennen ein.If the fan device is not in use for a long time while the boiler is in operation, disrepute the lead camps; complete burning also occurs.
Dieser Uebelstand soll nach der vorliegenden Erfindung dadurch vermieden werden, dafs hohle Wellen benutzt werden, die pyramidenförmig und gegebenenfalls in einander schiebbar zusammengesetzt sein können. . Die Welle wird vorteilhaft nach unten durch das Schornsteingehäuse hindurchgeführt, so dafs das Drucklager, welches das Gewicht der Welle und der Ventilatoreinrichtung aufnimmt, aufserhalb des Schornsteingehäuses liegt und mithin nicht durch Rufs, Flugasche u. 's. w. beeinflufst werden kann. Das Lager am oberen Schornsteinende kann leicht so ausgebildet werden, dafs das Zusetzen durch Rufs u. s. w. vermieden wird.According to the present invention, this disadvantage is to be avoided by the fact that hollow shafts are used, which are pyramid-shaped and optionally slidable into one another can be composed. . The shaft is advantageously down through the chimney casing passed through, so that the thrust bearing, which takes up the weight of the shaft and the fan device, is outside the Chimney housing and therefore not caused by call, fly ash and the like. w. be influenced can. The bearing at the upper end of the chimney can easily be designed in such a way that clogging due to calls etc. is avoided.
Die Zeichnung läfst eine hohle, pyramidenförmig zusammengesetzte, d. h. sich nach oben allmählich verjüngende Welle für das Ventilatorrad erkennen. Am oberen und unteren Ende der Welle sind Durchbrechungen ο und u vorgesehen, so dafs durch die ganze Länge, der Welle beständig ein Strom kalter Luft hindurchstreichen kann, welcher die Welle abkühlt. The drawing shows a hollow, pyramid-shaped composite, ie gradually tapering upward shaft for the fan wheel. At the upper and lower end of the shaft openings ο and u are provided so that a stream of cold air can constantly pass through the entire length of the shaft, which cools the shaft.
Durch die hohle Ausbildung können die Wellen verhältnifsmäfsig sehr leicht und trotzdem so kräftig ausgebildet werden, dafs auch bei den gröfsten Schiffen keine Zwischenlager zur Führung der Welle nothwendig sind.Due to the hollow design, the waves can be relatively light and yet be so vigorously developed that even the largest ships have no intermediate storage facilities are necessary to guide the shaft.
Selbstverständlich kann die Gestalt der Welle auch von der in der Zeichnung dargestellten abweichen, da es ja nur darauf ankommt, durch die Röhrenform der Welle diese so widerstandsfähig zu machen, dafs Zwischenlager nicht nöthig sind.Of course, the shape of the shaft can also differ from that shown in the drawing deviate, since the only thing that matters is to make the shaft so resistant through the tubular shape that it is an intermediate bearing are not necessary.
