PATENTANSPRÜCHEPATENT CLAIMS 1. Rollenumlaufschuh, dadurch gekennzeichnet, dass der Grundkörper (2) desselben mit mindestens einem Deformationsfühler (3) zur Messung der Belastung versehen ist.1. Recirculating roller shoe, characterized in that the base body (2) thereof is provided with at least one deformation sensor (3) for measuring the load. 2. Rollenumlaufschuh nach Anspruch 1, dadurch gekennzeichnet, dass der Deformationsfühler (3) in der unbelasteten Rollbahn (6) des Grundkörpers (2) angeordnet ist.2. Recirculating roller shoe according to claim 1, characterized in that the deformation sensor (3) is arranged in the unloaded runway (6) of the base body (2). BESCHREIBUNGDESCRIPTION Die vorliegende Erfindung betrifft einen Rollenumlaufschuh.The present invention relates to a circulating roller shoe. Es ist bekannt, dass die Belastung eines Rollenumlaufschuhs die Lebensdauer, Funktionsfähigkeit und Genauigkeit entscheidend beeinflusst.It is known that the load on a roller guide shoe has a decisive influence on its service life, functionality and accuracy. Eine Überbelastung hat die Zunahme des Rollwiderstandes und schliesslich die vorzeitige Zerstörung zufolge, während eine ungenügende Belastung dagegen die Bewegungsgenauigkeit (Funktionsgenauigkeit) und die Steifheit des Rollenumlaufschuhs verschlechtert.Overloading results in increase of rolling resistance and eventual premature destruction, while insufficient loading, on the other hand, degrades movement accuracy (operational accuracy) and rigidity of the LM Roller. Die gewünschte Funktionsfähigkeit des Rollenumlaufschuhs ist nur dann gewährleistet, wenn während der Benützung die Belastung des Rollenumlaufschuhs dem vorgeschriebenen Wert genau entspricht.The desired functionality of the roller guide shoe is only guaranteed if the load on the roller guide shoe exactly corresponds to the prescribed value during use. Zur Lösung dieser Aufgabe ist ein Messblock unter dem Namen DEFLEKTOMETER von der Firma INA/BRD bekannt geworden.To solve this problem, a measuring block has become known under the name DEFLEKTOMETER from the company INA/FRG. Der bekannte Messblock ermöglicht die Einstellung der Belastung und wird anstelle eines Rollenumlaufschuhs eingebaut. Durch Hydraulik wird ein gewünschter Spanndruck erzeugt und die zu diesem Spanndruck gehörende Deformation gemessen. Anschliessend wird der Rollenumlaufschuh wieder eingesetzt und mechanisch dem gemessenen Deformationswert entsprechend verspannt.The well-known measuring block enables the load to be adjusted and is installed instead of a recirculating roller shoe. A desired clamping pressure is generated by hydraulics and the deformation associated with this clamping pressure is measured. The circulating roller shoe is then reinserted and mechanically braced according to the measured deformation value. Der Mangel dieser bekannten Lösung liegt darin, dass die Belastung nur im Ruhezustand des Rollenumlaufschuhs erfolgen kann, und somit nur die Bestimmung der statischen Lage ermöglicht. Die zu den relativen Bewegungen gehörenden Kräfteänderungen werden nicht angezeigt. Ferner ist ein Ein- und Ausbau mit Arbeit, Zeit und Kosten verbunden, und es können leicht Fehler entstehen. Der Aufbau ist kompliziert und es werden Hilfsgeräte benötigt.The shortcoming of this known solution is that the load can only take place when the circulating roller shoe is in the idle state, and thus only enables the static position to be determined. The force changes associated with the relative movements are not displayed. Furthermore, assembly and disassembly involves labor, time and expense, and errors can easily occur. The structure is complicated and auxiliary equipment is required. Das Ziel der Erfindung ist die Behebung der obigen Mängel. Es wird ein Rollenschuh vorgeschlagen, welcher einfach und billig gestaltet ist und kontinuierlich funktioniert.The aim of the invention is to remedy the above shortcomings. A roller shoe is proposed which is simple and inexpensive in design and continuously functions. Die gesetzte Aufgabe beim Rollenumlaufschuh eingangsThe task set for the circulating roller shoe at the beginning 22 genannter Art wird erfindungsgemäss dadurch gelöst, dass der Grundkörper des Rollenumlaufschuhs mit mindestens einem Deformationsfühler zur Belastungsmessung versehen ist.of the type mentioned is achieved according to the invention in that the base body of the circulating roller shoe is provided with at least one deformation sensor for measuring the load. s Zum Schutz des Deformationsfühlers zur Belastungsmessung ist eine Ausführungsform von Vorteil, bei der der Deformationsfühler in der unbelasteten Rollbahn des Grundkörpers angeordnet ist.s To protect the deformation sensor for load measurement, an embodiment is advantageous in which the deformation sensor is arranged in the unloaded roller track of the base body. Ein Ausführungsbeispiel der Erfindung wird anschlies-lo send anhand der Zeichnung näher erläutert. Es zeigen:An exemplary embodiment of the invention is then explained in more detail with reference to the drawing. Show it: Fig. 1 den erfindungsgemässen Rollenumlaufschuh mit Belastungsmessung in Seitenansicht und Teilschnitt ;1 shows the circulating roller shoe according to the invention with load measurement in a side view and partial section; Fig. 2 eine Überansicht zu Fig. 1, nur teilweise dargestellt; 15 Fig. 3 eine Variante zu Fig. 2 ; undFIG. 2 is an overhead view of FIG. 1, shown only partially; 15 FIG. 3 shows a variant of FIG. 2; and Fig. 4 eine weitere Ausführungsform des erfindungsgemässen Rollenumlaufschuhs im Schnitt.4 shows a further embodiment of the roller shoe according to the invention in section. In den Fig. 1 und 2 ist der Rollenumlaufschuh mit 1 20 bezeichnet. Er weist einen Grundkörper 2 auf, welcher von einer Rollbahn 6 umgeben ist. Im oder am Grundkörper 2 ist ein Deformationsfühler 3 zur Messung der Belastung vorhanden, welcher Deformationsfühler 2 mit einer Leitung 4 mit einem Anzeigegerät (hier nicht dargestellt) verbunden 25 ist. Zweckmässigerweise befindet sich der Deformationsfühler 3 in der unbelasteten Rollbahn 6 des Grundkörpers 2.1 and 2, the roller recirculating shoe is denoted by 120. It has a base body 2 which is surrounded by a runway 6 . In or on the base body 2 there is a deformation sensor 3 for measuring the load, which deformation sensor 2 is connected 25 with a line 4 to a display device (not shown here). The deformation sensor 3 is expediently located in the unloaded runway 6 of the base body 2. Bei einer weiteren Ausführungsform gemäss Fig. 3 ist der Deformationsfühler 3 mit einem Anschluss 5 versehen, der am Rollenumlaufschuh 1 angeordnet ist und mit der Leitung 30 4 lösbar verbunden werden kann. Die Leitung 4 führt wiederum zu einem Anzeigegerät.In a further embodiment according to FIG. 3, the deformation sensor 3 is provided with a connection 5 which is arranged on the recirculating roller shoe 1 and can be detachably connected to the line 30 4 . The line 4 in turn leads to a display device. Der Deformationsfühler 3 kann als Dehnungsmesser, Halbleitermessstreifen oder Piezo-elektrischer Fühler usw. ausgebildet sein.The deformation sensor 3 can be in the form of a strain gauge, a semiconductor measuring strip or a piezoelectric sensor, etc. 35 Die Funktionsweise des beschriebenen Rollumlaufschuhs 1 wird nachstehend erläutert.The mode of operation of the roller skate 1 described is explained below. Der Rollenumlaufschuh 1 mit Grundkörper 2 erleidet während seines Betriebs ständige Deformationen.The circulating roller shoe 1 with the base body 2 suffers constant deformations during its operation. Das Wesentliche an diesen Deformationen ist, dass die 40 Belastung in der Mitte des Grundkörpers 2 nahezu konstant ist, während an beiden Enden des Grundkörpers beim Ein-und Austritt der Rollelemente die Belastung pulsierend auftritt.The essence of these deformations is that the load in the center of the base body 2 is almost constant, while the load occurs in a pulsating manner at both ends of the base body when the rolling elements enter and exit. Die entsprechenden Deformationen werden vom Defor-45 mationsfühler3 in elektrische Signale umgewandelt, die durch die Leitung 4 in das Anzeigegerät gelangen.The corresponding deformations are converted by the deformation sensor 3 into electrical signals, which are fed through line 4 to the display device. Beim erfindungsgemässen Rollenumlaufschuh 1 werden die Belastungsmessungen kontinuierlich ausgeführt, so dass die durch die Belastungen verursachten Deformationen kon-50 tinuierlich angezeigt werden.In the case of the circulating roller shoe 1 according to the invention, the load measurements are carried out continuously, so that the deformations caused by the loads are continuously displayed.
