Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Nach dieser Erfindung erhält die Wurzel von eingesetzten Zähnen eine eigenthümliche Querschnittsgestalt, die aus einer trapezförmigen und einer seitlich durch zwei Kreisbogen oder dergl. begrenzten Fläche besteht. Diese eigenthümliche, gewissermäfsen doppelte Keil- oder Schwalbenschwanzgestalt der Zahnwurzel giebt eine zuverlässige Sicherung gegen Lockerung der Zähne, indem die in der Verzahnung auftretenden Kräfte immer durch grofse Druckflächen auf den Radkörper übertragen werden.According to this invention, the roots of inserted teeth are given a peculiar character Cross-sectional shape consisting of a trapezoidal and a side by two circular arcs or The like. Limited area exists. These peculiar, to a certain extent double wedge or The dovetail shape of the tooth root provides a reliable safeguard against loosening of the teeth, in that the forces occurring in the toothing are always caused by large pressure surfaces be transferred to the wheel center.

Auf der Zeichnung sind in. Fig. 1 Theile zweier in Eingriff stehender Räder mit eingesetzten Zähnen der neuen Art veranschaulicht. a - α bezeichnet die auf Abscheerung beanspruchten Querschnitte.Parts of two meshing wheels with inserted teeth of the new type are illustrated in FIG. 1 of the drawing. a - α denotes the cross-sections subject to shear stress.

Zur gröfseren Sicherheit und Festigkeit im Sitz der Zähne in Richtung der Radachse können an der Zahnwurzel noch Einfräsungen oder dergl. vorgesehen und Material des Zahnbodens in dieselben eingestemmt werden.For greater safety and strength in the seat of the teeth in the direction of the wheel axis Millings or the like can also be provided on the tooth root and the material of the tooth base be wedged into the same.

Claims (1)

Patent-Anspruch:Patent claim: Einsetzbare Zähne für Zahnräder, dadurch gekennzeichnet, dafs die Zahnwurzeln doppelte Keil- oder Schwalbenschwanzgestalt besitzen, zum Zweck, eine sichere Befestigung der Zähne zu ermöglichen, trotzdem das zwischen den Zahnwurzeln stehenbleibende Material des Zahnkranzes breiter und kräftiger gehalten wird.Insertable teeth for gears, characterized in that the tooth roots double Have a wedge or dovetail shape for the purpose of securely attaching the teeth to enable, nevertheless, the material of the tooth ring remaining between the tooth roots is held wider and stronger. Hierzu 1 Blatt Zeichnungen.1 sheet of drawings.
