Description

Kombination einer Kraftmeßdose und. ihrer Lagerung Es ist bekannt, hohe Kräfte und große Gewichte mittels Kraftmeßdosen, z. B. mittels magnetoelastischer Kraftmeßdosen, zu messen. Bei den Kraftmeßdosen besteht aber die Schwierigkeit, daß man darauf achten muß, daß die Kraft genau senkrecht auf die Meßdose einwirkt. Querkräfte dürfen von der Meßdose nicht übertragen werden. Daher ist es vor allem bei Anlagen mit großen Abständen zwischen den Unterstützungspunkten schwierig, zuverlässige Meßresultate zu erhalten, weil bereits durch Temperaturschwankungen sehr beachtliche Querkräfte auftreten können, die das meßergebnis fälschen. Man hat Verschiedenes versucht, um die Querkräfte von der Meßdose fernzuhalten. Combination of a load cell and. their storage It is known high forces and large weights by means of load cells, e.g. B. by means of magnetoelastic Load cells to measure. With the load cells, however, there is the difficulty that one must make sure that the force acts exactly perpendicularly on the load cell. Lateral forces must not be transmitted by the load cell. Hence it is above all difficult, reliable in systems with large distances between the support points To obtain measurement results, because they are already very considerable due to temperature fluctuations Lateral forces can occur which falsify the measurement result. You have different things tries to keep the shear forces away from the load cell.

Durch eine bestimmte Kombination der Kraftmeßdose und ihrer Lagerung kann dies ebenfalls erreicht werden.By a certain combination of the load cell and its storage this can also be achieved.

Gemäß der Neuerung besteht die Kombination einer Kraftmeßdose und ihrer Lagerung darin, daß die Kraftmeßdose auf einem Vielkugellager ruht. Man kann auch diese Kombination so abwandeln, daß die Kugeln durch Rollen ersetzt werden, weil diese Rol- len aber in der Richtung der auftretenden Querkräfte verschieb- u bar sein müßten, liegen sie untereinander parallel. Für die 1 L Rollen oder Kugeln sieht man zweckmäßigerweise ebene Rollflä- chen vor. Dabei können die Rollen und Kugeln durch einen Käfig gegeneinander auf Abstand gehalten werden.According to the innovation, the combination of a load cell and its storage is that the load cell rests on a multi-ball bearing. This combination can also be modified in such a way that the balls are replaced by rollers, because these rollers len but shift in the direction of the occurring transverse forces u would have to be cash, they are parallel to each other. For the 1 L Rollers or balls are expediently seen as flat rolling surfaces before. The rollers and balls can be kept at a distance from one another by a cage.

Zur Erläuterung der Neuerung dient eine Figur. Diese zeigt bei 1 eine Kugel, auf welche die von der Meßdose zu tragende Last aufgesetzt wird. Unter der Kugel ist beispielsweise eine magnetoelastische Meßdose 2 vorgesehen, und um diese von jeder Querkraftwirkung frei zu halten, ist sie auf einem Vielkugel-oder Rollenlager 3 gelagert. Die Kugeln 4 sind von einem Käfig 5 auf Abstand gehalten. wenn statt der Kugeln Rollen verwendet werden, liegen die Rollen zueinander parallel, so daß eine Verschiebung in der zu erwartenden Richtung der Querkraft ohne weiteres möglich ist. Die Fläche, auf denen die Kugeln 3 oder die Rollen laufen, ist zweckmäßigerweise vollkommen eben.A figure is used to explain the innovation. This shows a at 1 Ball on which the load to be borne by the load cell is placed. Under the A magnetoelastic load cell 2 is provided, for example, and around this sphere It is to be kept free from any transverse force effect on a multi-ball or roller bearing 3 stored. The balls 4 are held at a distance by a cage 5. if instead of of the balls rollers are used, the rollers are parallel to each other so that a shift in the expected direction of the transverse force is easily possible is. The surface on which the balls 3 or the rollers run is expedient perfectly even.

Ein Vielkugellager ist an sich ein bekanntes Bauelement. Seine besondere Bedeutung für eine Meßdose liegt darin, daß durch das Vielkugellager nur lotrecht wirkende Drucke auf die Meßdoee übertragen werden, während Querkräfte auf das Vielkugellager oderRollenlager nicht übertragen werden. 3Schutzansprüche 1Blatt'Zeichnungen A multi-ball bearing is a known component per se. Its special importance for a load cell is that due to the multi-ball bearing, the pressure on the load cell is only perpendicular are transferred while transverse forces on the multi-ball bearing or roller bearings are not transferred. 3 Protection claims 1 sheet 'drawings
