KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Der Gegenstand vorliegender Erfindung gehört zu den Transmissions-Dynamometern, bei denen Schraubenfedern, die etwa in der Tangente oder Sehne der Umdrehung liegen, deformiert werden.The subject matter of the present invention belongs to the transmission dynamometers, where coil springs are roughly in the tangent or chord of the revolution, be deformed.
Bei Anwendung kurzer Federn erreicht man nur geringe Deformationen und mithin auch geringe Zeigerausschläge, da es infolge des sich störend geltendmachenden toten GangesIf short springs are used, only slight deformations are achieved, and consequently also small pointer deflections, as it is due to the annoying dead gear
ίο unratsam ist, eine Umwandlung der Zeigerbewegung durch Hebel ins Große vorzunehmen. ίο it is inadvisable to convert the pointer movement to make big by lever.
Es sind daher Apparate mit langen weichen Federn vorzuziehen, die aber den Nachteil haben, daß sich die Mittellinien der Federn bei Dehnung der Federn der Wellenmitte nähern, was einem Kürzerwerden der Hebelarme entspricht, weshalb auch hierbei die Länge der Federn nicht zu groß genommen werden kann. Zu berücksichtigen ist hierbei noch die Beeinflussung der längeren Federn durch die Zentrifugalkraft.Apparatuses with long, soft springs are therefore preferable, but they have the disadvantage have that the center lines of the springs are at the center of the shaft when the springs are stretched approach, which corresponds to a shortening of the lever arms, which is why the Length of the feathers cannot be taken too great. This has to be taken into account nor the influence of centrifugal force on the longer springs.
Diese Fehler werden durch die vorliegende Erfindung beseitigt. Wie aus der Zeichnung ersichtlich, ist die Riemscheibe a, auf der Welle drehbar gelagert, durch Stellringe gegen seitliche Verschiebungen geschützt. Neben der Riemscheibe befindet sich ein Doppelarm d, welcher mit der Welle fest verbunden ist. Dieser Arm ist durch Federn / mit der Riemscheibe verbunden (Fig. 2). Diese Federn werden nun in kürzeren Abständen durch die Pendelstützen f, g unterstützt. Bei zunehmender Belastung bzw. Verdrehung der Riemscheibe auf der Welle werden die Federn länger, wobei die Stützen f, g verhindern, daß die Federn sich der Achsmitte nähern.These errors are eliminated by the present invention. As can be seen from the drawing, the pulley a, rotatably mounted on the shaft, is protected against lateral displacement by adjusting rings. Next to the pulley there is a double arm d which is firmly connected to the shaft. This arm is connected to the pulley by springs / (Fig. 2). These springs are now supported at shorter intervals by the pendulum supports f, g . With increasing load or rotation of the pulley on the shaft, the springs become longer, with the supports f, g preventing the springs from approaching the center of the axle.
Mit der Belastung verändert sich der Verdrehungswinkel zwischen Riemscheibe und Doppelarm, was gemäß Fig. 1 auf den Anzeiger übertragen wird. Der Bewegung der Riemscheibe folgt zwangläufig durch Arm j die Büchse h, welche einen schraubenartigen Schlitz r besitzt. Stift s, der sich im Schlitz r bewegt, macht sodann eine seitliche Bewegung. Diese Verschiebung wird durch den Hebel 0, welcher bei k drehbar befestigt ist, auf den Zeiger übertragen.With the load, the angle of rotation between the pulley and the double arm changes, which is transferred to the indicator according to FIG. 1. The movement of the pulley is inevitably followed by the sleeve h, which has a screw-like slot r , through arm j. Pin s moving in slot r then makes a sideways movement. This shift is transmitted to the pointer by lever 0, which is rotatably attached at k.
