Description

Bei der Messung mechanischer Druck- oder Zugkräfte auf dem Weg über die Messung der durch solche Kräfte verursachten, ihnen proportionalen, elastischen Formänderungen, z. B. Durchbiegungen, ist es notwendig, den Verformungskörper vor Kräften zu bewahren, deren Größe die Elastizitätsgrenze des Verformungskörp ers überschreitet, damit die Anzeigegenauigkeit und Eichung des Meßkörpers nicht beeinträchtigt werden. When measuring mechanical compressive or tensile forces on the way over the measurement of the elastic, proportional, elastic forces caused by such forces Shape changes, e.g. B. deflections, it is necessary to front the deformation body To preserve forces, the size of which corresponds to the elastic limit of the deformation body exceeds, so that the accuracy of the display and the calibration of the measuring body are not impaired will.

Nach der vorliegenden Erfindung wird der Uberlastungsschutz auf besonders einfache und sichere Weise dadurch erzielt, daß der Meßkörper aus im wesentlichen drei Teilen zusammengesetzt ist, von denen zwei mittels gewinde so miteinander verbunden sind, daß das axiale Spiel des Gewindes den Betrag der elastischen Forinänderung des dritten Teils, nämlich des elastischen Verformungskörpers, beidseitig begrenzt. Die Unterteilung in drei Teile hat den für die Herstellung wichtigen Vorzug, daß jeder Teil aus demjenigen Material gefertigt werden kann, der für die Bearbeitung und den Verwendungszweck des betreftenden Teils am günstigsten ist. Zum Beispiel können in Abb. I der Unterteil 1 und Oberteil 2 aus einem für das Gewinde gut bearbeitbaren Material und der' Verformungskörper 3, der für den Wert des Geräts als Meßgerät entscheidend ist, aus bestem Federstahl gefertigt werden. According to the present invention, the overload protection becomes special simple and safe way achieved in that the measuring body from essentially is composed of three parts, two of which are connected to one another by means of a thread are that the axial play of the thread the amount of the elastic form change of the third part, namely the elastic deformation body, limited on both sides. The division into three parts has the important advantage that each part can be made from the material required for machining and the intended use of the part in question is most favorable. For example In Fig. I, the lower part 1 and upper part 2 can be made from a thread that can be easily machined Material and the 'deformation body 3, for the value of the device as a measuring device it is crucial to be made from the best spring steel.

An dem in Abb. I dargestellten Meßkörper kann zum Zweck der Messung der elastischen Verformung in das Innere eine beispielsweise elektrische Abtastvorrichtung so eingebracht werden, daß sie am Unter- und Oberteil anliegt und je nach der Größe der auf den Oberteil einwirkenden Kraft, dessen mehr oder weniger tiefes Einsinken in den Unterteil aufnimmt und in elektrische Werte umformt. On the measuring body shown in Fig. I, for the purpose of measurement the elastic deformation into the interior, for example an electrical scanning device be introduced so that it rests on the lower and upper part and depending on the size the force acting on the upper part, its more or less deep sinking in the lower part and converted into electrical values.

Für den vorliegenden Verwendungszweck sind besonders günstige Ausführungsarten für den Verformungsköfper neben Schrauben-, Platten- oder Tellerfedern der Rillenring nach Abb. 2 oder die Rillenscheibe nach Abb. 3. Solche Verformungskörper können als Körper nahezu gleicher Spannungsbeanspruchung bemessen werden und bieten deshalb beste Materialausnutzung. For the present purpose, there are particularly favorable designs for the deformation body, in addition to helical, plate or disc springs, the grooved ring according to Fig. 2 or the pulley according to Fig. 3. Such deformation bodies can can be measured as a body with almost the same stress load and therefore offer best material utilization.
