Die Erfindung betrifft einen Kraftmesser, welcher, an einem laufenden Transmissionsriemen angelegt, die von diesem beförderte Arbeitsleistung angibt. Diese stellt sich dar als Produkt der Riemengeschwindigkeit und der Differenz der Spannungen der beiden Riementrums.The invention relates to a dynamometer which, on a running transmission belt created, which indicates the work carried out by this. This is shown as the product of the belt speed and the difference in the tensions of the two Belt strums.
Bisher.. wurden Riemendynamometer stets derart ausgeführt, daß die Differenz der Spannung der beiden Trums gemessen wurde. Es sind dies z. B. das Riemendynamometer von Hefner-Alteneck, ferner von C. W. Siemens und von E. Thomson. Alle diese Dynamometer sind kompliziert und erfordern zum Teil eigene Installationen, um die Messung der übertragenen Arbeit auszuführen; zum Teil sind sie auch nur bei horizontal laufenden Riemen durchführbar. Die vorliegende Erfindung ermöglicht dagegen, die übertragene Arbeitsleistung in einfacher Weise und bei Riemen von jeder beliebigen Stellung zu messen.So far ... belt dynamometers have always been designed in such a way that the difference in tension between the two strands was measured. It are these z. B. the belt dynamometer from Hefner-Alteneck, also from C. W. Siemens and by E. Thomson. All of these dynamometers are complicated and some of them require their own Installations to carry out the measurement of the work delegated; in part they are also only feasible with horizontally running belts. The present invention enables on the other hand, the work done in a simple manner and with belts to measure from any position.
Auf der beiliegenden Zeichnung ist der neue Kraftmesser schematisch dargestellt.The new dynamometer is shown schematically in the accompanying drawing.
Bei dem Apparat ist eine Druckrolle 1 vorgesehen, zu welcher Laufrollen 2,2 unter einem bestimmten stumpfen Winkel angeordnet sind. Die Druckrolle 1 steht mittels eines Armes 3 mit einer Büchse 4 in Verbindung, an welcher die die Rollen 2, 2 tragenden Arme 11 sitzen. In der Büchse ist eine Druckfeder 5 vorgesehen, auf welche ein mit einem Druckknopf 7 versehener Kolben 6 oder eine Platte drückt. Die in die Büchse 4 einschiebbare Spindel 8 des Knopfes 7 ist zweckmäßig mit einer Skalenteilung versehen, um das Ablesen des Druckes der Rolle 1 gegen den Treibriemen 9 zu ermöglichen. Zu diesem Zwecke wird die Druckrolle 1 gegen den Treibriemen gepreßt, bis der Treibriemen so weit eingedrückt ist, daß er an den beiden Rollen 2, 2 anliegt. Der hierbei angewendete Druck bzw. die Riemenspannung kann an der Skalenteilung abgelesen werden.In the apparatus, a pressure roller 1 is provided, to which rollers 2, 2 are arranged at a certain obtuse angle. The pressure roller 1 is connected by means of an arm 3 to a bushing 4 on which the arms 11 carrying the rollers 2, 2 are seated. In the sleeve, a compression spring 5 is provided, on which a piston 6 or a plate provided with a push button 7 presses. The spindle 8 of the button 7, which can be pushed into the sleeve 4, is expediently provided with a graduated scale in order to enable the pressure of the roller 1 against the drive belt 9 to be read off. For this purpose, the pressure roller 1 is pressed against the drive belt until the drive belt is pressed in so far that it rests against the two rollers 2, 2. The pressure applied or the belt tension can be read from the graduations.
Die Rolle'ι kann mittels einer geeigneten Vorrichtung . mit einem Tourenzähler oder Tachometer verbunden sein. Auf diese Weise kann mittels des beschriebenen Apparates leicht durch das Produkt aus Riemenspannung und Riemengeschwindigkeit die Arbeitsleistung, welche durch den Riemen übertragen wird, bestimmt werden.The Rolle'ι can by means of a suitable device. with a tour counter or Speedometer connected. In this way, by means of the apparatus described the product of belt tension and belt speed easily improves work performance, which is transmitted through the belt can be determined.
