Description
KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die Erfindung betrifft ein Umdrehungsdynamometer. Das Neue besteht darin, daß die Kupplung zwischen treibenden und angetriebenen Organen durch einen Anker geschieht, der von einem Elektromagneten mit regelbarer Anziehungskraft angezogen wird.The invention relates to a revolution dynamometer. The new thing is that the Coupling between driving and driven organs is done by an anchor, which is attracted by an electromagnet with adjustable force of attraction.
In der Zeichnung stellt α eine Transmissionswelle dar, b die auf dieser sitzende Riemenscheibe. Die Arbeit dieser Riemenscheibe sollIn the drawing, α represents a transmission shaft, b the pulley sitting on it. This pulley is supposed to work
ίο gemessen werden. Die Riemenscheibe wird zu diesem Zwecke gelöst, indem man den Keil, mit dem sie auf der Welle gehalten wird, entfernt und die Kupplung mit der Welle mittels der dargestellten Meßvorrichtung vornimmt. Diese besteht aus einer Nabe c mit den Anschlägen d und e; der Anschlag d ist als Elektromagnet ausgebildet, dessen Anker f, der zwischen den Anschlägen d und c spielen kann, fest mit irgendeinem geeigneten Punkt der Riemenscheibe b verbunden ist. Die Nabe c trägt ferner den Bürstenhalter g mit den Bürsten h. Die Bürsten schleifen auf den Kontaktringen i, die feststehen und mit einer Stromquelle, einem Strommesser, der Wicklung des Magneten sowie einem Regulierwiderstand einen Stromkreis bilden.ίο be measured. For this purpose, the pulley is loosened by removing the key with which it is held on the shaft and coupling it to the shaft by means of the measuring device shown. This consists of a hub c with stops d and e ; the stop d is designed as an electromagnet whose armature f, which can play between the stops d and c , is firmly connected to any suitable point on the pulley b . The hub c also carries the brush holder g with the brushes h. The brushes slide on the contact rings i, which are stationary and form a circuit with a power source, an ammeter, the winding of the magnet and a regulating resistor.
Die Messung geschieht durch Einstellung des Regulierwiderstandes, der die Stromstärke bzw. die Amperewindungen der Spule des Elektromagneten beeinflußt. Die Benutzung des Dynamometers ist die folgende:The measurement is made by setting the regulating resistor, which controls the current strength or the ampere turns of the coil of the electromagnet influenced. The usage of the dynamometer is the following:
Man läßt zunächst bei Inbetriebsetzung der zu messenden Maschine die volle Kraft des Magneten wirken, die sicher die Riemenscheibe b mitnimmt. Dann schwächt man allmählich den Strom, bis der mit der Riemenscheibe fest verbundene Anker f abreißt und nun von dem Mitnehmeranschlag e der Nabe c aufgefangen wird, was mittels Signal irgendwelcher Art wahrnehmbar gemacht wird. Die elektrischen Meßinstrumente geben die Zugkraft des Magneten in dem Augenblick des Abreißens des Ankers an.When the machine to be measured is started up, the full force of the magnet is allowed to act, which safely takes the pulley b with it. Then the current is gradually weakened until the armature f, which is firmly connected to the pulley, breaks off and is now caught by the driver stop e of the hub c , which is made perceptible by means of a signal of some kind. The electrical measuring instruments indicate the pulling force of the magnet at the moment the armature is torn off.
