Description
Reibräder-Wechselgetriebe. Reibrädergetriebe, bei welchen die Reibscheiben vermittels einer Feder gegen das Reibrad gleichmäßig gedrückt werden, sind bereits bekannt, jedoch hat diese Anordnung den Nachteil, daß der zum Betrieb erforderliche Anpressungsdruck während des Betriebes nicht geregelt oder unterbrochen und dadurch das Getriebe stillgelegt werden kann. Gemäß der Erfindung wird diesem Mangel dadurch abgeholfen, daß die Anpressung der Reibscheibe vermittels einer unter Wirkung der Druckfeder stehenden Zwischenscheibe erfolgt, in deren zylindrischem Teil Nocken von auf der Reibscheibenwelle befestigten, aber drehbar gelagerten Armen greifen, die anderseits Rollen tragen und durch einen verschiebbaren Kegel bewegt werden.Friction wheel change gear. Friction gears, in which the friction disks are pressed evenly against the friction wheel by means of a spring, are already known, but this arrangement has the disadvantage that the required for operation Contact pressure not regulated or interrupted during operation and thereby the transmission can be shut down. According to the invention, this shortcoming is eliminated helped that the pressure of the friction disc by means of an under the effect of Compression spring standing washer takes place, in the cylindrical part of which cams grip from arms attached to the friction disk shaft but rotatably mounted, which, on the other hand, carry roles and are moved by a displaceable cone.
In der Zeichnung ist der Gegenstand der Erfindung dargestellt.In the drawing, the subject matter of the invention is shown.
Auf der Welle a ist die Reibscheibe c befestigt, während die Reibscheibe d verschiebbar angeordnet ist. Außerdem ist fest mit der Welle a verbunden die Hülse b, welche die beiden Arme e trägt, die mit je einer Rolle f versehen sind. Über dieser Hülse b und der verschiebbaren Scheibe g ist die Hülse i eiregeschraubt. Die Hülse schiebt sich über die Hülse b und über dieser Hülse i ist .der Verschiebungskonus k angeordnet.The friction disk c is attached to the shaft a, while the friction disk d is arranged to be displaceable. In addition, the sleeve b, which carries the two arms e, which are each provided with a roller f, is firmly connected to the shaft a. The sleeve i is screwed onto this sleeve b and the displaceable disk g. The sleeve slides over the sleeve b and above this sleeve i. The displacement cone k is arranged.
Die Wirkungsweise des Getriebes ist folgende Der in der Zeichnung oberhalb der Welle a dargestellte Teil der Kupplungseinrichtung zeigt die Feder h in Wirkung gegen die Reibscheibe d. Sobald die Scheibe d die Reibrolle s berührt, wird durch die Wirkung der Feder h auf die Hülse b die Welle q und gleichzeitig die Reibscheibe P verschoben, und zwar so lange, bis die Scheibe c die Reibrolle v berührt. Der Druck, mit welchem die beiden Scheiben c und d gegen die Reibrollen gepreßt werden, ist abhängig von der Spannung der Feder h. Das Spannen der Feder h geschieht vermittels der Zwischenscheibe g und der darin angeordneten Stellschrauben 1.The mode of operation of the transmission is as follows: The part of the coupling device shown in the drawing above the shaft a shows the spring h in action against the friction disk d. As soon as the disk d touches the friction roller s, the action of the spring h on the sleeve b shifts the shaft q and the friction disk P at the same time until the disk c touches the friction roller v. The pressure with which the two disks c and d are pressed against the friction rollers depends on the tension of the spring h. The spring h is tensioned by means of the intermediate disk g and the adjusting screws 1 arranged therein.
Soll die Kraftübertragung unterbrochen werden, so wird der Kegel k so weit verschoben, bis die Rollen f in den zylindrischen Teil des Kegels k gelangen; dadurch werden die an den Armen e befindlichen Nocken n die Hülse i so weit nach rechts schieben, bis die Stellung, wie unterhalb der Welle a gezeichnet, erreicht ist. In dieser Stellung berühren die Stellschrauben 1 die Reibscheibe d nicht mehr, so daß die Kraftübertragung unterbrochen ist.If the power transmission is to be interrupted, the cone k is shifted until the rollers f get into the cylindrical part of the cone k; as a result, the cams n located on the arms e will push the sleeve i so far to the right until the position shown below the shaft a is reached. In this position, the adjusting screws 1 no longer touch the friction disk d, so that the power transmission is interrupted.
