Description
Hydraulisches, aus Geber und Empfänger bestehendes Fernübertragungssystem Bei vielen Prüf- bzw. Meßanordnungen ist es notwendig, daß die Anzeige von der Meßstelle räumlich getrennt wird. Die dabei erforderliche Fernübertragung der zu messenden und anzuzeigenden Kräfte und/oder Stellungen wird meist auf elektrischem Wege durchgeführt. Hierzu sind aufwendige Wandleranlagen notwendig, ferner ist bei Stromausfall eine Meßwertübertragung nicht mehr möglich.Hydraulic remote transmission system consisting of a transmitter and receiver With many test or measuring arrangements it is necessary that the display is from the measuring point is spatially separated. The required remote transmission of the to be measured and forces and / or positions to be displayed is usually carried out electrically. Complex converter systems are necessary for this, and in the event of a power failure, a Transfer of measured values is no longer possible.
Es ist bereits eine Anordnung zum Verschieben eines Einstellgliedes bekanntgeworden, bei welcher zur Übertragung pneumatische oder hydraulische Mittel vorgesehen sind. Die Anordnung erlaubt jedoch nur eine digitale, d. h. unstetige Fernübertragung von Werten. Darüber hinaus macht sie ebenfalls von elektrischen Hilfseinrichtungen Gebrauch.It is already an arrangement for moving an adjusting member became known in which pneumatic or hydraulic means for transmission are provided. However, the arrangement only allows a digital, i. H. discontinuous Remote transmission of values. In addition, she also makes of electric Auxiliary equipment use.
Ziel der Erfindung ist die Schaffung eines hydraulischen, aus Geber und Empfänger bestehenden Fernübertragungssystems zur analogen, kraftverlustfreien Übertragung von Meßkräften und/oder zur analogen, spielfreien Übertragung von Meßstellungen.The aim of the invention is to create a hydraulic, from encoder and receiver existing long-distance transmission system for analog, power loss-free Transmission of measuring forces and / or for the analog, backlash-free transmission of measuring positions.
Erfindungsgemäß wird die gestellte Aufgabe dadurch gelöst, daß Geberkolbenstange und Empfängerkolbenstange in Axixalkugelführungen gelagert sind, daß Geber- und Empfängerkolben durch Rollmembranen gegen den Zylinder abgedichtet sind und daß die Meß- und/oder Rückstellfeder am Empfänger angeordnet ist.According to the invention, the object is achieved in that the master piston rod and receiver piston rod are mounted in axixal ball guides that encoder and Receiver pistons are sealed against the cylinder by rolling diaphragms and that the measuring and / or return spring is arranged on the receiver.
Ein weiteres, einer zweckmäßigen Weiterführung der Erfindung dienendes Merkmal besteht darin, daß Geber- und Empfängerkolben verschiedene Durchmesser aufweisen.Another, an expedient continuation of the invention serving The characteristic is that the transmitter and receiver pistons have different diameters.
Die vorgeschlagene Verwendung von Axialkugelführungen in Verbindung mit Rollmembranen führt zu einer fast vollständigen Reibungsfreiheit. Die vorgesehenen Rollmembranen garantieren darüber hinaus weitgehende Spielfreiheit. Die Spielfreiheit wird noch dadurch unterstützt, daß die als Rückstell- und/ oder Meßorgan vorgesehene Feder nicht im Geber, sondern im Empfänger angeordnet ist, wodurch das hydraulische Übertragungsmittel ständig unter Druck gehalten wird.The proposed use of axial ball guides in conjunction with rolling diaphragms leads to an almost complete freedom from friction. The intended Rolling membranes also guarantee extensive freedom from play. The freedom of play is also supported by the fact that the provided as a return and / or measuring element The spring is not located in the transmitter but in the receiver, which means that the hydraulic Transmission medium is kept under pressure at all times.
In der Zeichnung ist eine beispielsweise Ausführung der erfindungsgemäß ausgebildeten Vorrichtung dargestellt.The drawing shows an example embodiment of the invention trained device shown.
In der Figur zeigt 1 das Gebergehäuse. In dieses eingebaut ist. die Kugelführung 2, die die Kolbenstange 3 axial führt. An der Kolbenstange 3 befindet sich der Kolben 4, über den die Rollmembran 5 gestülpt ist. Von dem Geberzylinderraum 6 wird das Druckmedium bei Betätigung der Kolbenstange in Pfeilrichtung in den Zylinderraum 7 des Empfängers gedrückt. Dadurch wird der Kolben 8 des Empfängers axial verschoben. Die Feder 9 kann entweder als Druckmeßfeder oder lediglich als Rückstellfeder ausgelegt sein. Die Kolbenstange 10 des Empfängers verschiebt sich dabei in eindeutiger, analoger Zuordnung zur Verschiebung der Geberkolbenstange 3 in der Kugelführung 11 des Empfängerzylinders 12.In the figure, 1 shows the encoder housing. In this is built. the Ball guide 2, which guides the piston rod 3 axially. Located on the piston rod 3 the piston 4, over which the rolling diaphragm 5 is placed. From the master cylinder space 6 the pressure medium is moved into the cylinder chamber when the piston rod is actuated in the direction of the arrow 7 pressed on the receiver. As a result, the piston 8 of the receiver is displaced axially. The spring 9 can either be designed as a compression measuring spring or merely as a return spring be. The piston rod 10 of the receiver moves in a clear, analogous way Assignment to the displacement of the master piston rod 3 in the ball guide 11 of the receiver cylinder 12th
Der Meßwert wird durch den Zeiger 13 auf einer Skala 14 sichtbar gemacht.The measured value is made visible by the pointer 13 on a scale 14.
Durch Wahl verschiedener Durchmesser der Kolben 4, 8 hat man es in der Hand, die Übertragung unter Beibehaltung der Stetigkeit in weiten Grenzen zu variieren. Hierdurch wird die Möglichkeit der Anpassung an die verschiedensten Meßprobleme geschaffen.By choosing different diameters of the pistons 4, 8 you have it in the hand, the transfer while maintaining the continuity within wide limits vary. This makes it possible to adapt to a wide variety of measurement problems created.
