Description

Keilrollenbremse zum plötzlichen Stillsetzen der Wellen von Lochmaschinen, Stanzen und ähnlichen 1Vlaschinen. Die Erfindung betrifft ein _Klemmgesperre zum plötzlichen Feststellen der Antriebswellen von Lochmaschinen u. dgl.Wedge roller brake for suddenly stopping the shafts of punching machines, Punching machines and similar machines. The invention relates to a _Klemmgesperre for sudden locking of the drive shafts of punching machines and the like.

Keilbremsen sind in verschiedenen Ausführungen bekannt, haben aber alle den Fehler, daß sie sich beim Bremsen festklemmen und dann nur schwer zu lösen sind.Wedge brakes are known in various designs, but have all have the fault that they get stuck when braking and are then difficult to loosen are.

Die Erfindung besteht darin, daß ein keilartiger Bremsschuh einerseits mittels Rollen gegen das Widerlager, andrerseits gegen die zu bremsende Welle gepreßt wird.The invention consists in that a wedge-like brake shoe on the one hand pressed against the abutment by means of rollers, on the other hand against the shaft to be braked will.

An Lochmaschinen und Stanzen sind meist Bandbremsen im Gebrauch, die eine ziemlich große Kraft zum Bremsen benötigen; letztere muß durch Fußtritt jedesmal überwunden werden und ermüdet daher den Arbeiter sehr.Band brakes are mostly used on punching machines and punching machines need quite a lot of force to brake; the latter must be kicked every time be overcome and therefore tires the worker very much.

In Fig. x ist eine Keilrollenbremse gelöst. In Fig. 2 ist sie festgezogen.In Fig. X, a wedge roller brake is released. In Fig. 2 it is tightened.

Es ist a die zu bremsende Welle; ö die Bremsauflage, c der keilartige Bremsschuh; d sind die Rollen; e ist das Widerlager für den Bremsschuh, f ein Auge für den Bremshebel. Soll nun die in Pfeilrichtung sich drehende Welle gebremst werden, so -wird der Bremsschuh soweit mit der Wellendrehung gedreht, bis die Bremsauflage b an der Welle zur Anlage kommt; die umlaufende Welle zieht dann je nach der Geschwindigkeit den Bremsschuh fest an, und es folgt ein sehr starkes Bremsen, was zur Folge hat, daß Stanzen u. dgl. mit Keilrollenbremse nicht nachschlagen, und daß Unglücksfälle verhütet -werden.It is a the shaft to be braked; ö the brake pad, c the wedge-like one Brake shoe; d are the roles; e is the abutment for the brake shoe, f is an eye for the brake lever. If the shaft rotating in the direction of the arrow is to be braked, so -the brake shoe is rotated with the shaft rotation until the brake pad b comes to rest on the shaft; the rotating wave then pulls depending on the speed the brake shoe firmly on, and very strong braking follows, which results in that punching and the like with wedge roller brake do not look up, and that accidents be prevented.

Da der Bremsschuh mit seinem Rücken auf Rollen gelagert ist, _läßt sich die Bremse wieder leicht lösen.Since the back of the brake shoe is mounted on rollers, it leaves the brake can be easily released again.
