Description

Mitnehmer für Anzeigegeräte, insbesondere für solche von Prüfmaschinen Bei Pendelwaagen für Prüfmaschinen und ähnlichen Einrichtungen bewegt der Pendelhebel ieine in Lagern gleitende Stange, die mit Hilfe- von Rüdern c. dgl. dien Zeiger bewegt. Damit nun die Zeigerstange immer in Berührung mit dem Pendelhebel bleibt, wird jetzt fast ausschließlich sein Gegenzug angebracht, der aus seiner Schnur, einer Ablenkrolle-und einem kleinen Gewicht besteht. Die Schwere des.Gewichtes darf nicht zu gering sein, damit bei schniellen:Bewegungen des Pendels kein Abklapgen der Stange vom Pendel eintritt. Mit einem solch leri Gegenzug sind verschiedene Nachteile verbunden und bestehen darin, daß der Schnurzug das aus-, ggeglichene Pendel aus seiner theoretischen Nullage ablenkt, wodurch :die mathematischen Beziehungen der Pendelwaage gestört werden .und .daß -durch die Ablenkrolle eine Reibung hervorgerufen wird, die höchst unerwünscht ist, da die Reibungen des Anzeigegerätes an und für sich schon ;einen Fehler. in die Messung hineintragen. Dieser wird um so größer, j e kleiner die Bendelgewichte sind.Carriers for display devices, in particular for testing machines In pendulum scales for testing machines and similar devices, the pendulum lever moves A rod sliding in bearings, which with the help of rudders c. the pointer emotional. So that the pointer rod always remains in contact with the pendulum lever, is now almost exclusively attached to its counter-tension, which is made of its cord, consists of a pulley and a small weight. The severity of the weight may not be too low, so that with rapid: movements of the pendulum no swinging away the rod enters from the pendulum. With such a leri counter-move are different Disadvantages connected and consist in the fact that the cord pulls the equalized The pendulum deflects from its theoretical zero position, whereby: the mathematical relationships the pendulum balance are disturbed and that the deflection roller causes friction which is highly undesirable because the friction of the display device on and for already; a mistake. into the measurement. This becomes all the greater the smaller the Bendelweights are.

Zur Vermeidung .dieser Nachteile wird en feidungsgemäß der Schnurzug mit seinem Gegengewicht durch reine an dem Taststift .der Anzeigestange befestigte Feder ersetzt, die um den Mitnehmer herumgreift und die Anzeigestange mit dem Mitnehmer in dauernder Bierührung hält. Abb, i zeigt die bisherige Bauart mit Gegenzug.In order to avoid these disadvantages, the pull cord is used attached with its counterweight by pure on the stylus .der indicator rod Replaces the spring that grips around the driver and the indicator rod with the driver keeps in constant beer guidance. Fig, i shows the previous design with counter-pull.

Abb. a und 3 zeigen eine beispielsweise und schematische- Ausführungsform des Erfindungsgegenstandes.Figs. A and 3 show an example and schematic embodiment of the subject matter of the invention.

In bekannter Weise liegt der an der Pendelstange i sitzende Mitnehmer a gegen den Taststift 3 der Anveigestange 4, die über Zahnstange 5 und gädchßn 6 den- Zeiger 7 bewegt. 8 ist die Skala. ErfiadungsgemäB ist an der Anzeigestange 4 :eine leichte Feder 9 derart angebracht, daß sie hinter den Mitnehmer 2 greift und den Taststift mit geringer Kraft gegen dien Mitnehmer drückt. Dadurch ist in beiden Richtungen der Pendelbewegung die Mitnahme der Anzeigestange gesichert. Der Vorteil dieser Mitnahme liegt in ,dem Wegfall zusätzlicher Reibungskräfte, der Verhinderung des 'Abklappens und in der Einfachheit sowie Billigkeit der Ausführung.The driver seated on the pendulum rod i lies in a known manner a against the stylus 3 of the Anveigestange 4, the rack 5 and gädchßn 6 the pointer 7 moves. 8 is the scale. According to the invention, it is on the display rod 4: a light spring 9 is attached in such a way that it engages behind the driver 2 and presses the stylus with little force against the driver. This means that in both directions of the pendulum movement secured the entrainment of the indicator rod. Of the The advantage of this entrainment lies in the elimination of additional frictional forces, the prevention of the folding and in the simplicity and cheapness of the execution.
