Description
Befestigung von Leistung übertragenden 1Vlaschinenteilen auf Wellen, insbesondere bei Flugmotoren Es ist bei schnellaufenden Brennkraftmaschinen, insbesondere Flugmotoren, gebräuchlich, Leistung übertragende Maschinenteile in der Weise mit den Wellen zu verbinden, daß die Welle als Keilwelle ausgebildet wird und in die Nabe des aufzusetzenden, Leistung übertragenden Maschinenteiles eine entsprechende Anzahl Nuten eingezogen werden. Trotz genauester Ausführung wird jedoch bei einer derartigen Verbindung, falls nicht strammer Preßsitz angewendet wird, nie ein so genaues Tragen sämtlicher Keilflanken erreicht, daß die Verbindung den hohen Beanspruchungen durch die Zünddrucke und Drehschwingungen stets mit Sicherheit gewachsen ist.Fastening of power-transmitting 1-cylinder parts on shafts, in particular in aircraft engines It is in high-speed internal combustion engines, in particular Aircraft engines, in common use, with power-transmitting machine parts to connect the shafts that the shaft is designed as a splined shaft and into the Hub of the machine part to be set up and transferring power a corresponding Number of grooves to be drawn. Despite the most precise execution, however, one such a connection, unless a tight interference fit is used, never such a connection accurate wearing of all wedge flanks ensures that the connection can withstand high stresses through which the ignition pressures and torsional vibrations have always grown with certainty.
Nach der Erfindung soll eine Verbesserung dieser Befestigung in der Weise erreicht werden, daß in die Welle nach dem Aufschieben des Leistung übertragenden Maschinenteiles eine kegelförmige Hülse eingepreßt und hierdurch die Welle so ausgebildet wird, daß die Keilflanken fest gegeneinander verspannt werden.According to the invention, an improvement in this attachment in the Way can be achieved that in the shaft after the postponement of the power-transmitting Machine part pressed in a conical sleeve and thereby the shaft is formed is that the wedge flanks are firmly braced against each other.
In der Zeichnung ist eine beispielsweise Ausführungsform: in Abb. i im Längsschnitt und in Abb. 2 im Querschnitt dargestellt.The drawing shows an example of an embodiment: in Fig. i shown in longitudinal section and in Fig. 2 in cross section.
Es bezeichnet a die Welle mit den mit ihr aus einem Stück bestehenden Teilen b, c den von der Welle mitzunehmenden, Leistung übertragenden Maschinenteil - im Beispiel einen Kupplungsflansch -, der mit seinen Nuten möglichst genau auf das Keilprofil der Welle paßt. d ist die außen kegelförmige Druckhülse, die durch die Mutter e fest in die kegelförmig ausgebohrte Welle hineingepreßt wird und diese so aufweitet, daß ein Verspannen der Keilflanken erzielt wird und wechselnde Drehkräfte kein Lockerwerden der Verbindung mehr herbeiführen können.It denotes a the shaft with the one made of one piece with it Parts b, c the power-transmitting machine part to be carried along by the shaft - in the example a coupling flange - with its grooves as precisely as possible the spline of the shaft fits. d is the externally conical pressure sleeve that passes through the nut e is pressed firmly into the conically drilled shaft and this widened so that a bracing of the wedge flanks is achieved and alternating torsional forces can no longer bring about a loosening of the connection.
