Description
Zeigerantrieb für Fliehkraftgeschwindigkeitsmesser mittels Schraubenganges. Bei Zeigerantrieben für Fliehkraftgeschwindigkeitsmesser mittels Schraubenganges nach Patent q.32309 ist es von der größten Bedeutung, daß die Übertragung der Kraft von den Pendelgewichten auf den Zeiger durch die Zwischenorgane unter möglichst geringen Reibungsverlusten erfolgt; insbesondere muß erreicht werden, daß die Kraft der Pendelgewichte trotz der versetzten Lagerung der Pendelachse zur Zeigerachse nur drehend auf den Schraubengang einwirkt, ihn aber nicht seitlich zu drücken sucht. Diesem Zwecke dient die firn folgenden beschriebene Ausführung.Pointer drive for centrifugal speedometer by means of a screw. With pointer drives for centrifugal speedometers by means of a screw thread according to patent q.32309 it is of the greatest importance that the transmission of power from the pendulum weights to the pointer through the intermediate organs under as possible low friction losses takes place; in particular must be achieved that the force the pendulum weights despite the offset mounting of the pendulum axis to the pointer axis acts only in a rotating manner on the screw thread, but does not seek to push it sideways. The embodiment described below serves this purpose.
Abb. I zeigt eine Seitenansicht. Abb. 2 bis 5 sind Einzelheiten.Fig. I shows a side view. Figures 2 through 5 are details.
Wie im Hauptpatent ist a die angetriebene Welle mit den Schwunggewichten b, die einen Stift c gegen einen an der Zeigerachse d sitzenden Schraubengang f drücken. Um die Kraft der Schwunggewichte b auf die Zeigerachse d zu übertragen, sind die beiden Lenker i der Schwunggewichte durch ein Gelenk 2 mit Gelenkachse 3 verbunden. Das untere Ende des Stiftes c ist abgeflacht und bildet eine Gabel q., die lose über die Achse 3 greift. Infolge dieser Bauart wird ohne feste Verbindung zwischen den Teilen I und c der Stift c um seine Längsachse gedreht. Infolgedessen wirkt er lediglich vortreibend auf den Schraubengang, drückt aber diesen nicht zur Seile. Um die Reibung zwischen Stift und Schraubengang noch weiter zu vermindern, ist am oberen Ende desselben eine Stahlkugel 5 eingelassen.As in the main patent, a is the driven shaft with the flyweights b, which has a pin c against a screw thread f seated on the pointer axis d to press. In order to transfer the force of the flyweights b to the pointer axis d, are the two links i of the swing weights through a joint 2 with a joint axis 3 connected. The lower end of the pin c is flattened and forms a fork q. that loosely grips over axle 3. As a result of this design there is no fixed connection between parts I and c, the pin c rotated about its longitudinal axis. Consequently it only has a driving effect on the screw thread, but does not push it back Ropes. To further reduce the friction between the pin and the screw thread, a steel ball 5 is embedded at the upper end of the same.
Die überragenden Enden der Gabel dienen zur Führung der Feder h, die bei kleineren Umdrehungsgeschwindigkeiten die Zentrifugalkraft der Gewichte unterstützen soll. Das untere Ende der Feder k ruht auf einer Führungsschraube 7, die durch eine Längsbohrung 6 zwecks Regelung der Federspannung verstellt werden kann.The protruding ends of the fork are used to guide the spring h, the support the centrifugal force of the weights at lower speeds target. The lower end of the spring k rests on a guide screw 7, which is through a Longitudinal bore 6 can be adjusted for the purpose of regulating the spring tension.
