AT 394 276 BAT 394 276 B
Die vorliegende Erfindung betrifft einen Rollenumlaufschuh mit einer Einrichtung zur Belastungsmessung.The present invention relates to a roller circulating shoe with a device for load measurement.
Es ist bekannt, daß die den Rollenumlaufschuh beanspruchende Belastung die Lebensdauer, Funktionsfähigkeit und Genauigkeit entscheidend beeinflußt.It is known that the load on the roller circulating shoe has a decisive influence on the service life, functionality and accuracy.
Eine Überbelastung hat die vorzeitige Zerstörung und die Zunahme des Rollwiderstandes zufolge.Overloading has resulted in premature destruction and increased rolling resistance.
Eine ungenügende Belastung verschlechtert die Bewegungsgenauigkeit (Funktionsgenauigkeit) und die Steifheit der Anordnung.An insufficient load deteriorates the accuracy of movement (functional accuracy) and the rigidity of the arrangement.
Die gewünschte Funktion des Rollenumlaufschuhes ist dann gewährleistet, wenn während der Benützung die Belastung des Rollenumlaufschuhes genau der vorgeschriebenen entspricht.The desired function of the roller circulation shoe is guaranteed if the load on the roller circulation shoe corresponds exactly to the prescribed one during use.
Zur Lösung dieser Aufgabe ist ein Meßblock namens DEFLEKTOMETER der Firma INA/BRD bekannt geworden.To solve this problem, a measuring block called DEFLEKTOMETER from INA / BRD has become known.
Der bekannte Meßblock dient zur Einstellung der Belastung der Rollenumlaufschuhe, wobei er anstelle eines Rollenumlaufschuhes eingebaut wird, durch Hydraulik der entsprechende bzw. gewünschte Spanndruck erzeugt und die zu diesem Spanndruck gehörende Deformation gemessen wird. Danach wird der Rollenumlaufschuh in seine Stelle zurückgesetzt und mechanisch bis zu der vorher gemessenen Deformationsgröße verspannt.The known measuring block is used to adjust the load on the roller circulating shoes, it being installed instead of a roller circulating shoe, the corresponding or desired clamping pressure being generated by hydraulics and the deformation associated with this clamping pressure being measured. Then the roller circulating shoe is put back into its place and mechanically clamped up to the previously measured deformation size.
Der Mangel der bekannten Lösung liegt darin, daß die Belastungsmessung nur im Ruhezustand des Rollenumlaufschuhes erfolgen kann und nur für die Bestimmung der statischen Kräfte fähig ist, jedoch die zu den relativen Bewegungen gehörenden Kräfteänderungen nicht anzeigt. Weiters benötigen Ein- und Ausbau Arbeit, Zeit und Kosten und können auch zu einer Fehlerquelle werden; der Aufbau ist kompliziert und Hilfsgeräte werden benötigtThe deficiency of the known solution lies in the fact that the load measurement can only take place in the idle state of the roller circulation shoe and is only capable of determining the static forces, but does not indicate the changes in force associated with the relative movements. Furthermore, installation and expansion require work, time and costs and can also become a source of errors; the structure is complicated and auxiliary devices are required
Die Zielsetzung der Erfindung liegt in der Abschaffung der obigen Mängel, d. h. in Gestaltung eines einfachen, billigen, kontinuierlich funktionierenden und einfach einbaubaren Rollenumlaufschuhes mit einer Einrichtung zur Belastungsmessung, wobei die Aufgabe der Erfindung darin gesehen wird, einen Rollenumlaufschuh mit Belastungsmeßfähigkeiten auszugestalten.The aim of the invention is to overcome the above shortcomings, i. H. in the design of a simple, inexpensive, continuously functioning and easily installable roller circulation shoe with a device for load measurement, the object of the invention being seen in designing a roller circulation shoe with load measurement capabilities.
Die gesetzte Aufgabe wird bei einem Rollenumlaufschuh der eingangs genannten Art erfindungsgemäß dadurch gelöst daß im und/oder am Grundkörper des Rollenumlaufschuhes zumindest ein Deformationsfühler zur Belastungsmessung angeordnet istThe object is achieved in a roller circulation shoe of the type mentioned in the invention in that at least one deformation sensor for load measurement is arranged in and / or on the base body of the roller circulation shoe
Zum Schutz des Deformationsfühlers mit Belastungsmessung ist eine Ausführungsform von Vorteil, bei welcher der Deformationsfühler zur Belastungsmessung in der unbelasteten Rollbahn des Grundkörpers angeordnet ist.To protect the deformation sensor with load measurement, an embodiment is advantageous in which the deformation sensor for load measurement is arranged in the unloaded runway of the base body.
Die Erfindung ist im folgenden an Hand eines Ausführungsbeispieles in der Zeichnung näher erläutert. In dieser zeigen Fig. 1 einen erfindungsgemäßen Rollenumlaufschuh in Seitenansicht und Teilschnitt, Fig. 2 eine teilweise Draufsicht auf diesen Rollenumlaufschuh, Fig. 3 in einer Darstellung wie Fig. 2 eine Ausführung mit anderem Anschluß einer Leitung und Fig. 4 eine weitere Ausführungsform des erfindungsgemäßen Rollenumlaufschuhes im Schnitt.The invention is explained below with reference to an embodiment in the drawing. 1 shows a roller circulation shoe according to the invention in side view and partial section, FIG. 2 shows a partial top view of this roller circulation shoe, FIG. 3 shows a representation like FIG. 2 shows an embodiment with a different connection of a line, and FIG. 4 shows a further embodiment of the invention Roller circulation shoe in the cut.
Wie der Zeichnung zu entnehmen ist, besitzt der erfindungsgemäße Rollenumlaufschuh in seinem Grundkörper einen Deformationsfühler (3) zur Belastungsmessung. Der Deformationsfühler (3) ist vorzugsweise in die unbelastete Rollbahn (6) des Grundkörpers (2) eingebaut. Der Deformationsfühler (3) ist über eine Leitung (4) mit einem Anzeigegerät verbunden, das hier nicht dargestellt ist.As can be seen in the drawing, the roller circulating shoe according to the invention has a deformation sensor (3) in its base body for measuring the load. The deformation sensor (3) is preferably installed in the unloaded runway (6) of the base body (2). The deformation sensor (3) is connected via a line (4) to a display device, which is not shown here.
Bei einer weiteren Ausführungsform des erfindungsgemäßen Rollenumlaufschuhes (1) ist der Deformationsfühler (3) mit einem Anschluß verbunden, der an dem Rollenumlaufschuh (1) angeordnet ist.In a further embodiment of the roller circulation shoe (1) according to the invention, the deformation sensor (3) is connected to a connection which is arranged on the roller circulation shoe (1).
An den Anschluß (5) ist ein Anzeigegerät, das nicht dargestellt ist, über die Leitung (4) anschließbar.A display device, which is not shown, can be connected to the connection (5) via the line (4).
Der Deformationsfühler (3) zur Belastungsmessung kann als Dehnungsmeß- oder Halbleitermeßstreifen oder als piezoelektrischer Fühler etc. ausgebildet sein.The deformation sensor (3) for load measurement can be designed as a strain gauge or semiconductor measuring strip or as a piezoelectric sensor etc.
Die Funktionsweise des erfindungsgemäßen Rollenumlaufschuhes (1) mit einer Einrichtung zur Belastungsmessung ist im folgenden kurz dargelegt. Der eingebaute Rollenumlaufschuh (1) unterliegt während seines Betriebes ständigen Deformationen und dementsprechend auch sein Grundkörper (2).The mode of operation of the roller circulating shoe (1) according to the invention with a device for measuring the load is briefly described below. The built-in roller shoe (1) is subject to constant deformation during operation and, accordingly, its base body (2).
Das Wesentliche an diesen Deformationen liegt darin, daß sie in der Belastungszone des Grundkörpers (2) nahezu gleich, an seinen beiden Enden bei dem Ein- und Austritt der Rollelemente jedoch von pulsierender Art ist. Diese Deformation wird von dem Deformationsfühler (3) in elektrische Signale umgewandelt, die über die Leitung (4) zu einem Anzeigegerät gelangen.The essence of these deformations is that they are almost the same in the loading zone of the base body (2), but are pulsating at both ends when the rolling elements enter and exit. This deformation is converted by the deformation sensor (3) into electrical signals which reach a display device via line (4).
Der erfindungsgemäße Rollenumlaufschuh (1) führt die Messungen kontinuierlich aus, sodaß er die Änderungen der Belastung zu jeder Zeit anzeigen kann. -2-The roller circulating shoe (1) according to the invention carries out the measurements continuously, so that it can display the changes in the load at any time. -2-
