Abstract

A roller shoe comprising a body 2 having a guide track for the rollers is provided with at least one deformation sensor/transducer 3 mounted on the body 2 for measuring the load. The sensor/transducer 3 may be a strain gauge, a piezo-electric, a semi-conductive strip or a magnetostrictive element which is preferably mounted on a portion of the body not directly loaded, ie in the track 6 on the top surface of body 2 or in a bore in the body. Continuous load monitoring is thus provided. <IMAGE>

Description

Die Erfindung betrifft einen Rollenumlaufschuh mit Belastungsmessung.The invention relates to a roller circulation shoe with load measurement.

Es ist bekannt, daß die den Rollenumlaufschuh beanspruchende Belastung die Lebensdauer, die Funktionsfähigkeit und die Genauigkeit entscheidend beeinflußt.It is known that the load on the roller circulating shoe the lifespan, functionality and accuracy are decisive influenced.

Eine Überbelastung hat die vorzeitige Zerstörung und die Zunahme des Rollwiderstandes zur Folge.Overload has the premature destruction and increase in Rolling resistance result.

Eine ungenügende Belastung verschlechtert die Bewegungsgenauigkeit (Funk­ tionsgenauigkeit) und die Steifigkeit des Gesamtsystems.An insufficient load deteriorates the accuracy of movement (radio accuracy) and the rigidity of the overall system.

Die gewünschte Funktion des Rollenumlaufschuhes ist dann gewährleistet, wenn während des Betriebs die aktuelle Belastung des Rollenumlaufschuhes der vorgeschriebenen Belastung genau entspricht.The desired function of the roller circulation shoe is then guaranteed if the current load on the roller circulation shoe during operation corresponds exactly to the prescribed load.

Als Lösung dieser Aufgabe ist ein Meßblock namens DEFLEKTOMETER von der Firma INA/BRD bekannt.A measuring block called DEFLEKTOMETER by known by the company INA / FRG.

Der bekannte Meßblock dient zur Einstellung der Belastung der Rollenum­ laufschuhe, wobei er anstelle des Rollenumlaufschuhes eingebaut wird, hy­ draulisch der entsprechende (gewünschte) Spanndruck erzeugt wird und inzwi­ schen die zu diesem Spanndruck gehörende Deformation gemessen wird. Da­ nach wird der Rollenumlaufschuh wieder eingebaut und dann mechanisch bis zur vorher gemessenen Deformationsgröße verspannt.The known measuring block is used to adjust the load on the rollers running shoes, whereby it is installed instead of the roller roller shoe, hy drastically the corresponding (desired) clamping pressure is generated and meanwhile the deformation associated with this clamping pressure is measured. There after the roller circulation shoe is reinstalled and then mechanically until clamped to the previously measured deformation quantity.

Ein Mangel der bekannten Lösung liegt darin, daß die Belastungsmessung nur im Ruhezustand des Rollenumlaufsschuhes erfolgen kann; so kann nur die Bestimmung des statischen Zustandes erfolgen und die zu den Relativbewe­ gungen gehörenden Kräfteänderungen werden nicht angezeigt. Ferner bedarf der Ein- und Ausbau Arbeit, Zeit und Kosten, die auch zur Fehlerquelle werden können, der Aufbau ist kompliziert und es sind Hilfsgeräte erforder­ lich. A shortcoming of the known solution is that the load measurement can only take place when the roller roller shoe is at rest; only that can Determination of the static state and the relative movements Changes in force that do not appear are not displayed. Further needs the installation and expansion work, time and costs, which also become a source of errors the structure is complicated and auxiliary devices are required Lich.  

Die Zielsetzung der Erfindung liegt in der Vermeidung der obigen Mängel, d. h. in der Gestaltung eines einfachen, billigen, kontinuierlich funktionieren­ den und einfach einbaubaren Rollenumlaufschuhes mit Belastungsmessung.The aim of the invention is to avoid the above shortcomings, d. H. in the design of a simple, cheap, work continuously and easy to install roller roller shoe with load measurement.

Die Aufgabe der Erfindung besteht darin, die Belastung des Rollenumlauf­ schuhes auch während dessen Betriebs zu messen.The object of the invention is the load on the roller circulation to measure shoes during its operation.

Die gesetzte Aufgabe bei dem Rollenumlaufschuh eingangs genannter Art wird erfindungsgemäß dadurch gelöst, daß zur Belastungsmessung im und/oder am Grundkörper des Rollenumlaufschuhes wenigstens ein Deformationsfühler angeordnet ist.The task set for the roller roller shoe of the type mentioned is achieved according to the invention in that the load measurement in and / or at least one deformation sensor on the base body of the roller circulation shoe is arranged.

Zum Schutz des die Belastungsmessung durchführenden Deformationsfühlers ist eine Ausführungsform von Vorteil, bei welcher der Deformationsfühler in der unbelasteten Rollbahn des Grundkörpers angeordnet ist.To protect the deformation sensor performing the load measurement is an embodiment of advantage in which the deformation sensor in the unloaded runway of the base body is arranged.

Die Erfindung wird im folgenden anhand eines aus der Zeichnung ersichtli­ chen Ausführungsbeispieles näher erläutert. In der Zeichnung zeigtThe invention is in the following ersichtli from the drawing Chen exemplary embodiment explained in more detail. In the drawing shows

Wie es aus der Zeichnung ersichtlich ist, weist der erfindungsgemäße Rollen­ umlaufschuh in seinem Grundkörper 2 einen Deformationsfühler 3 zur Bela­ stungsmessung auf. As can be seen from the drawing, the roller circulating shoe according to the invention has in its base body 2 a deformation sensor 3 for load measurement.

Bei einer weiteren bevorzugten Ausführungsform ist der Deformationsfühler 3 in die unbelastete Rollbahn 6 des Grundkörpers 2 eingebaut.In a further preferred embodiment, the deformation sensor 3 is installed in the unloaded runway 6 of the base body 2 .

Der Deformationsfühler 3 zur Belastungsmessung ist über eine Leitung 4 mit einem Anzeigegerät verbunden, das hier nicht gezeigt ist.The deformation sensor 3 for load measurement is connected via a line 4 to a display device, which is not shown here.

Bei einer weiteren Ausführungsform des erfindungsgemäßen Rollenumlauf­ schuhs 1 mit Belastungsmessung ist der Deformationsfühler 3 entsprechend Fig. 3 mit einer Anschlußbuchse 5 verbunden, die an dem Rollenumlaufschuh 1 angeordnet ist. An der Anschlußbuchse 5 kann ein Anzeigegerät, das hier nicht dargestellt ist, mittels einer mit einem Stecker versehenen Leitung 4 angeschlossen werden.In a further embodiment of the roller circulation shoe according to the invention 1 with load measurement is the deformation sensor 3 corresponding to FIG. 3 connected to a connection socket 5 which is arranged on the roller circulation shoe 1.

Die Funktionsweise des erfindungsgemäßen Rollenumlaufschuhes 1 mit Bela­ stungsmessung wird im Folgenden kurz dargelegt.The mode of operation of the roller circulation shoe 1 according to the invention is briefly described below.

Der eingebaute Rollenumlaufschuh 1 mit Belastungsmessung wie auch sein Grundkörper 2 ist während seines Betriebes ständigen Deformationen unter­ worfen. Das Wesentliche bei diesen Deformationen liegt darin, daß diese in der Belastungszone des Grundkörpers 2 nahezu konstant, an dessen beiden Enden bei dem Ein- und Austritt der Rollelemente jedoch vom pulsierenden Charakter sind.The built-in roller shoe 1 with load measurement as well as its base body 2 is subjected to constant deformations during its operation. The essence of these deformations lies in the fact that they are almost constant in the loading zone of the base body 2 , but are pulsating in character at both ends when the rolling elements enter and exit.

Diese Deformationen werden von dem im Bereich eines Endes des Grundkör­ pers 2 angeordneten Deformationsfühler 3 in elektrische Signale umgewan­ delt, die über die Leitung 4 einem Anzeigegerät zugeführt werden.These deformations are converted by the deformation sensor 3 arranged in the region of one end of the basic body 2 into electrical signals which are fed via line 4 to a display device.

Der erfindungsgemäße Rollenumlaufschuh 1 mit Belastungsmessung führt die Messungen kontinuierlich durch, so daß er die bei der Belastung entstehenden Veränderungen zu jeder Zeit anzeigen kann.The roller circulating shoe 1 according to the invention with load measurement carries out the measurements continuously, so that it can display the changes occurring during the load at any time.
