KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Den Gegenstand der Erfindung bildet ein Antrieb für hin und her oder schwingend oder kreisend bewegte Vorrichtungen, wie z. B. Schüttel- oder Schwingsiebe, Plansichter, Förderrinnen u. dgl., der die Rückwirkung der durch die bewegten Massen erzeugten Stöße auf die Gebäudeteile usw. vermeidet.The subject of the invention is a drive for back and forth or swinging or circling devices such. B. shaking or vibrating screens, plansifters, conveyor troughs and the like, which avoids the impact of the shocks generated by the moving masses on the parts of the building, etc.
Nach der Erfindung wird die Schüttel- oder Schwingbewegung dadurch herbeigeführt, daßAccording to the invention, the shaking or rocking movement is brought about that
ίο man ruhende Gewichtsmassen an der Vorrichtung (Sieb ο. dgl.) selbst oder einem damit sich bewegenden Teile oder an einem festen Teile frei pendelnd aufhängt oder auf einer wagerechten Unterlage frei verschiebbar lagert und die Trägheit der ruhenden Masse dazu benutzt, einen Widerlagerdruck für die treibende Kraft zu erzeugen.ίο one resting weight on the device (Sieve ο. Like.) Itself or a moving part with it or on a fixed one Parts hangs freely pendulum or stored freely movable on a horizontal base and the inertia of the stationary mass is used to create an abutment pressure for the driving To generate power.
In der Zeichnung sind verschiedene Ausführungsmöglichkeiten dieses Erfindungsgedankens dargestellt.In the drawing are various possible embodiments of this inventive concept shown.
In Fig. ι ist an einem hin und her zu bewegenden Siebe b, das von Pendeln α getragen wird, ein schweres Gewicht g gelenkig aufgehängt. An diesem Gewicht g ist eine auf beliebige Weise, z.B. mittels Elektromotors, gedrehte Antriebkurbel k gelagert, die durch eine Schubstange s mit dem Siebe b gelenkig verbunden ist. Bei entsprechender Masse des Gewichtes, Höhe der Umlaufzahl und Eigenschwingung des Pendelgewichtes g sind die auf letzteres wirkenden Kräfte nicht imstande, es in erhebliche Schwingungen zu versetzen, so daß das Sieb b sich gegen das ruhig oder verhältnismäßig ruhig hängende Gewicht g bewegt.In Fig. Ι a heavy weight g is hinged to a screen b to be moved back and forth and carried by pendulums α. A drive crank k rotated in any way, for example by means of an electric motor, is mounted on this weight g and is articulated to the sieve b by a push rod s. With a corresponding mass of the weight, the number of revolutions and natural oscillation of the pendulum weight g , the forces acting on the latter are not able to set it in considerable vibrations, so that the sieve b moves against the calmly or relatively calmly hanging weight g .
In Fig. 2 ist das Gewicht g, statt an der zu bewegenden Vorrichtung (Sieb V) selbst, an der Gebäudedecke f aufgehängt. An der Wirkung ändert sich dadurch gegenüber der Ausführung nach Fig. 1 ebensowenig wie bei der Vorrichtung nach Fig. 3, nach der das Gewicht g frei beweglich auf einer wagerechten Unterlage d ruht, auf der auch beispielsweise das Sieb b mittels Stützen e stehen kann.In Fig. 2 the weight g, instead of the device to be moved (sieve V) itself, is suspended from the building ceiling f. On the effect at 1 nor changes by comparison with the embodiment according to FIG. As in the device according to Fig. 3, after which the weight g freely movable on a dare right pad d rests on the well, for example, the wire b by means of supports e can stand.
An Stelle der einfachen Trägheit der Gewichtsmassen kann auch die gyrostatische Eigenschaft eines umlaufenden, symmetrisch zu seiner Drehachse verteilten Gewichtes benutzt werden. Da die Verdrehung eines gyrostatischen Kreisels aus seiner ursprünglichen Umlaufebene eine erhebliche Kraft erfordert, so kann der Gyrostat als Widerlager zur Aufnahme der durch die Betriebskraft erzeugten Gegenkraft ganz im Sinne der Fig. 1 dienen.Instead of the simple inertia of the weights, the gyrostatic Property of a rotating weight distributed symmetrically to its axis of rotation will. Because the twisting of a gyrostatic top from its original Orbital plane requires considerable force, the gyrostat can be used as an abutment to accommodate serve the counterforce generated by the operating force entirely in the sense of FIG.
