Description

Durch Fliehkraft betätigtes Schlagwerkzeug, Die Erfindung betrifft ein derrch Fliehkraft betätigtes Schlagwerkzeug. Das Neue besteht darin, daß der Schlagkörper mit der Antriebswelle durch ein biegsames Zwischenstück verbunden ist. Vorzugsweise besteht das Zwischenstück aus einer oder mehreren Flachfedern. .Centrifugal impact tool, The invention relates to an impact tool operated by centrifugal force. The new thing is that the Impact body is connected to the drive shaft by a flexible intermediate piece. The intermediate piece preferably consists of one or more flat springs. .

In der Zeichnung ist ein Ausführungsbeispiel eines solchen Hammers im Schnitt senkrecht zur Achse dargestellt.In the drawing is an embodiment of such a hammer shown in section perpendicular to the axis.

Der Schlagkörpera ist mit dem frei schwingenden Ende einer Blattfeder b, welche mit dem anderen Ende auf der Antriebswelle c sitzt, fest verbunden.The impact body is with the freely oscillating end of a leaf spring b, which sits with the other end on the drive shaft c, firmly connected.

Der Schlagkörper wird bei jeder Drehung der Welle nach innen gedrückt, wobei in der Feder Energie aufgespeichert wird. Beim Freiwerden. des Schlagkörpers wird er mit der ihm durch die Fliehkraft mitgeteilten Beschleunigung und der in der Feder aufgespeicherten Energie nach vorn geschleudert.The impact body is pressed inwards with every rotation of the shaft, energy is stored in the spring. When you become free. of the impact body it becomes with the acceleration communicated to it by the centrifugal force and the in energy stored by the spring is thrown forward.
