Gerät zur Messung des Radius einer KehlungDevice for measuring the radius of a valley
Die vorliegende Erfindung betrifft ein Gerät zur unmittelbaren Messung des Radius einer Kehlung, insbesondere derjenigen einer Kugellager-Lauffläche.The present invention relates to a device for directly measuring the radius of a fillet, in particular that of a ball bearing running surface.
Die Kontrolle des Radius von Kugellager-Laufflächen wird zur Zeit folgendermassen durchgeführt: Man legt eine Lehre in die Kehle und prüft von Auge, ob der zu prüfende Radius demjenigen der Lehre entspricht. Um dies an einem äusseren Kugellagerring durchzuführen, muss dieser gebrochen werden, so dass die Prüfung einerseits nicht zerstörungsfrei, und ausserdem wegen der beim Brechen möglichen Deformationen, auch nicht zuverlässig ist. Zudem verlangt das Verfahren ein subjektives Urteil, was zu einer gewissen Streuung der Ergebnisse führt.The control of the radius of ball bearing running surfaces is currently carried out as follows: One lays a gauge in the throat and checks visually whether the radius to be checked corresponds to that of the gauge. To do this on one to carry out the outer ball bearing ring, it must be broken so that the test on the one hand is not non-destructive, and is also not reliable because of the possible deformations when breaking. In addition, the procedure requires a subjective judgment, which leads to a certain dispersion of the results.
Des weiteren ist ein Gerät zur Messung derThere is also a device for measuring the
Bogenhöhe über eine bestimmte, durch eine Hülse festgelegte Sehne bekannt, welches aber zur Bestimmung des Radius eine komplexe Rechnung verlangt.Arch height over a certain, fixed by a sleeve chord known, but which is used to determine the radius complex calculation required.

Es ist das Ziel der Erfindung, diese Nachteile zu beheben und ein Gerät zu schaffen, welches ohne Rechnung eine rasche, genaue und zerstörungsfreie Bestimmung des Kehlradius gestattet.It is the aim of the invention to remedy these disadvantages and to provide a device which, without calculation allows rapid, precise and non-destructive determination of the fillet radius.
Das erfindungsgemässe Gerät ist dadurch gekennzeichnet, dass es eine Anordnung von Hebeln variabler Länge aufweist, welche den Wert der Aenderungen einer Bogenhöhe über einer Sehne in Bewegungen umwandelt, die den Aenderungen des Radius entsprechen.The device according to the invention is characterized in that it has an arrangement of levers of variable length which converts the value of the changes in an arch height above a chord into movements that correspond to the changes of the radius.
Die Zeichnung zeigt beispielsweise zwei Ausführungsformen des erfindungsgemässen Gerätes.The drawing shows, for example, two embodiments of the device according to the invention.
Die Fig. 1 zeigt eine von der Messspindel 5 welche die Bogenhöhe über der Hülse 6 misst - ausgehende Uebertragung mittels eines Hebels 2, welcher so ausgelegt ist, dass er dem Stift der Messuhr 1 eine Bewegung erteilt, die der Abweichung des Kehlradius R von seinem Sollwert entspricht, Das Verhältnis l/L der Hebelarme muss gleich dem Verhältnis f/R sein. Letzteres ändert sich nach der FormelFig. 1 shows one of the measuring spindle 5, which measures the arch height above the sleeve 6 - outgoing Transmission by means of a lever 2, which is designed so that it gives the pin of the dial indicator 1 a movement that corresponds to the deviation of the fillet radius R from its nominal value. The ratio l / L of the lever arms must be equal to the ratio be f / r. The latter changes according to the formula

wobei C die Sehnenlänge (Durchmesser der Hülse 6) ist. Die Kurvenscheibe 4 auf der Messspindel 5 bewirkt beim Kippen des Hebels eine Aenderung seines Hebelarmverhältnisses, welche der Aenderung des Verhältnisses f/R hinreichend angepasst ist.where C is the chord length (diameter of the sleeve 6). the When the lever is tilted, the cam disk 4 on the measuring spindle 5 changes its lever arm ratio, which the change in the ratio f / R is adequately adapted.
Die Figur 2 gibt schematisch eine Ausführungsform wieder, welche ebenfalls zu einer Veränderung des Hebelarmverhältnisses in Abhängigkeit der Winkellage des Hebels führt, indem die Krümmung des Auflagers 7 beim Kippen des Hebels eine Verschiebung des Auflagepunktes 8 bewirkt.FIG. 2 schematically shows an embodiment which also leads to a change in the lever arm ratio depending on the angular position of the lever, the curvature of the support 7 when tilting the Shifts the support point 8 with the lever.
