Description

Vorrichtung zum Verbinden von Nabe und Welle. Bei den bisherigen Verbindungen einer Nabe mit einer Welle, deren gebräuchlichste Keil und Stellschraube sind, besteht der Übelstand, daß der oder die Träger der Verbindung weder mit der Welle noch mit der Nabe so verbunden sind, daß nicht bei Lösung der Verbindung ein Bestandteil desselben, z. B. Keil, Stellschraube, Stift usw., verlorengehen kann. Dies ist hauptsächlich bei Verbindttrigen kleiner Maschinenteile, z. B. solchen der Feinmechanik, ein empfindlicher Mangel. Durch die Erfindung wird dieser Mangel beseitigt, da die, neue Verbindung ohne Anwendung von Werkzeugen leicht lösbar und wiederherstellbar ist, ohne daß ihre Bestandteile frei werden und verlorengehen können, Nach der Erfindung wird ein als offener Ring ausgebildeter Runddraht, dessen eines Ende winkelrecht zu dem Ring abgebogen ist, mit seinem Ringteil in Ringnuten, mit seinem geraden Teil in Längsnuten der Welle und der Nabe eingelegt. Dabei ist die Ringnut auf der Welle so tief, daß der Ringteil der Vorrichtung bis auf den Wellendurchmesser zusammengedrückt werden kann und dann die Nabe seitlich verschoben, also abgezogen werden kann. Um ein leichteres oder schwereres Abziehen der Nabe zu erreichen, wird die Ringnut in der Nabe entweder dreieckig: oder halbrund ausgebildet. Der Ringteil der Vorrichtung ist ein nicht ganz geschlossener Kreis, so daß die Vorrichtung nach dem Einsetzen nicht mehr ohne Absicht von der Welle lösbar ist.Device for connecting hub and shaft. With the previous connections a hub with a shaft, the most common of which is a key and set screw the disadvantage that the bearer or carriers of the connection neither with the shaft nor with the hub are connected in such a way that not a component when the connection is loosened same, e.g. B. wedge, set screw, pin, etc., can be lost. This is mainly when connecting small machine parts, e.g. B. those of precision engineering, a sensitive one Defect. This deficiency is eliminated by the invention, since the new connection can be easily detached and restored without the use of tools, without its constituents can be released and lost, according to the invention a round wire designed as an open ring, one end of which is at right angles to the Ring is bent, with its ring part in ring grooves, with its straight part in Inserted longitudinal grooves of the shaft and the hub. The ring groove is on the shaft so deep that the ring part of the device is compressed to the shaft diameter and then the hub can be moved sideways, so it can be pulled off. Around To achieve easier or harder removal of the hub, the annular groove either triangular or semicircular in the hub. The ring part of the device is a not completely closed circle, so that the device after insertion can no longer be unintentionally detached from the shaft.

Auf der Zeichnung ist die Erfindung näher veranschaulicht. Abb. i zeigt die Vorrichtung allein, Abb. a auf der Welle sitzend, Abb. 3 die mit einer dreieckigen Nut versehene Nabe und Abb. ¢ die fertige Verbindung.The invention is illustrated in more detail in the drawing. Fig.i shows the device alone, Fig. a sitting on the shaft, Fig. 3 the one with a triangular groove provided hub and Fig. ¢ the finished connection.

Die Vorrichtung besteht aus einem offenen Ringteil a und einem winkelrecht dazu abgebogenen geraden Teil d. Die Welle b besitzt eine Ringnut e, die so tief ist, daß der Ringteil a auf den Wellendurchmesser zusammengedrückt werden kann. Die Ringnut f in der Nabe c ist in dem dargestellten Ausführungsbeispiel dreieckig ausgebildet, so daß das Abziehen der Nabe erleichtert wird. Die entsprechenden Längsnuten in Welle und Nabe sind g und h. Die Herstellung der Verbindung geschieht durch Aufstoßen der Nabe auf die Welle, die Lösung durch seitlichen Stoß oder Druck auf die Nabe.The device consists of an open ring part a and a straight part d bent at right angles thereto. The shaft b has an annular groove e which is so deep that the ring part a can be compressed to the shaft diameter. The annular groove f in the hub c is triangular in the illustrated embodiment, so that the removal of the hub is facilitated. The corresponding longitudinal grooves in the shaft and hub are g and h. The connection is made by pushing the hub onto the shaft, the solution by pushing the hub from the side or by applying pressure.
