Selbstzentrierendes Klemmfutter.Self-centering clamping chuck.

Zusatz zum Patent 346645.Addendum to patent 346645.

Patentiert im Deutschen Reiche vom 12. Mai 1921 ab. Längste Dauer: 29. November 1935.Patented in the German Empire on May 12, 1921. Longest duration: November 29, 1935.

Gegenstand des Hauptpatentes ist ein selbstzentrierendes Klemmfutter, bei dem das Kegeltriebrad durch einen Spreizring gegen achsiale Verschiebung gesichert ist. Gemäß der Zusatzerfindung sind der Spreizring und die Nut des Gehäuses, gegen welche er sich stützt, so gestaltet, daß die achsiale Verschiebung des Kegeltriebes während des Betriebes verhindert wird, daß aber beim Auseinandernehmen der Spreizring einem kräftigen Drucke nachgibt. Dies kann beispielsweise dadurch erreicht werden, daß der Spreizring kreisförmigen Querschnitt und die Nut im Gehäuse des Spannfutters halbkreisförmigen Querschnitt hat.The subject of the main patent is a self-centering clamping chuck in which the bevel gear is secured against axial displacement by an expanding ring. According to the additional invention the expansion ring and the groove of the housing, against which it is supported, are designed in such a way that that the axial displacement of the bevel drive is prevented during operation, but that when the Spreader ring gives way to strong pressure. This can be achieved, for example be that the expansion ring circular cross-section and the groove in the housing of the chuck has a semicircular cross-section.

Ein Ausführungsbeispiel ist in der Zeichnung dargestellt, die einen Querschnitt durch das Klemmfutter zeigt. Der Kegeltrieb 5 dreht sich im Gehäuse 1 und verstellt dabei durch den Zahnkranz 4 die Spannbacken 3. Der Spreiz-An embodiment is shown in the drawing, which shows a cross section through the Chuck shows. The bevel gear 5 rotates in the housing 1 and adjusted by the Toothed ring 4 the clamping jaws 3. The expanding

ao ring 6, der aus einem runden Stahldraht hergestellt ist, legt sich infolge seiner Federkraft gegen die halbkreisförmige Nut im Gehäuse 1. Soll das Kegeltriebrad 5 herausgenommen j werden, so wird der Deckel 2 entfernt. Wird ; dann auf das Kegeltriebrad ein kräftiger ach- «5 [ sialer Druck zum Beispiel durch Hammerschläge ; ausgeübt, so wird der Spreizring 6 in die Nut 7 des Kegeltriebes hineingedrückt, so daß er das weitere Herausschieben des Kegeltriebrades nicht verhindert.ao ring 6, which is made of a round steel wire, lies against the semicircular groove in the housing 1 due to its spring force. If the bevel gear 5 is to be removed, the cover 2 is removed. Will ; then to the cone drive wheel a strong ACh "5 [sialer pressure, for example by hammer blows; exerted, the expansion ring 6 is pressed into the groove 7 of the bevel drive so that it does not prevent the further pushing out of the bevel pinion.

Eine Sicherung dieser Art ist äußerst einfach und sehr betriebssicher.A backup of this type is extremely simple and very reliable.
