Description
2020th
Die Erfindung beirifft ein Gerät zur Anzeige der erfolgten Beanspruchung einer Maschine mit einem induktiven Impulsgeber an einer bei Betrieb der Maschine umlaufenden Welle, der pro Umdrehung der Welle mindestens einen elektrischen Impuls liefert und mit einem elektromechanischen Zählwerk, das von einer elektronischen Schalteinrichtung jeweils dann betätigt wird, wenn ein zugehöriger Kondensator auf einen vorbestimmten Wert aufgeladen ist.The invention relates to a device for displaying the results Loading of a machine with an inductive pulse generator on one when the machine is in operation rotating shaft that delivers at least one electrical pulse per revolution of the shaft and with one electromechanical counter, which is then actuated by an electronic switching device, when an associated capacitor is charged to a predetermined value.
Zur Einhaltung von Wartungsfristen oder zur Feststellung des Ablaufes von Garantiezeiten bei Maschinen sind mechanische oder elektrische Zähler bekannt, die die zurückgelegte Betriebszeit der Maschine, z. B. in 3s Stunden, anzeigen, oder deren Zählerstand in direktem Verhältnis zu der Anzahl von erfolgten Umdrehungen einer beliebigen Maschinenwelle stehen.To comply with maintenance deadlines or to determine the expiry of warranty periods for machines mechanical or electrical counters are known that the operating time of the machine, e.g. B. in 3s hours, or their meter reading in direct Relative to the number of revolutions performed by any machine shaft.
Ein derartiger Zähler ist z. B. aus der DE-OS 20 44 353 bekanntSuch a counter is z. B. from DE-OS 20 44 353 known
Diese Zähler können den Einfluß von Belastungsschwankungen auf die Lebensdauer der Maschine nicht berücksichtigen.These counters cannot reduce the influence of load fluctuations on the service life of the machine consider.
Bei Maschinen mit großem Betriebsdrehzahlbereich steht die Belastung, der Verschleiß und damit auch die Lebensdauer oftmals auch in einem bestimmten Verhältnis zu der Höhe der Drehzahl, mit der diese Maschinen betrieben werden.In machines with a large operating speed range, the load, the wear and thus also the The service life is often related to the speed with which these machines are used operate.
Weil, entsprechend dem Induktivgesetz von Faraday, die Größe der elektromotorischen Kraft des !impulses des induktiven Impulsgebers von der Geschwindigkeit abhängt, mit dem die Spulen des Impulsgebers von den Feldlinien des Magneten des Impulsgebers geschnitten wird, ist die Größe des Impulses direkt proportional der Drehzahl der Maschinenwelle.Because, according to Faraday's law of inductance, the magnitude of the electromotive force of the pulse of the inductive pulse generator depends on the speed at which the coils of the pulse generator are removed from the Field lines of the magnet of the pulse generator is cut, the size of the pulse is directly proportional to the Speed of the machine shaft.
Die Aufgabe der Erfindung besteht darin, einen Umdrehungszähler für derartige Maschinen so auszubilden, daß in dessen Zählerstand neben der Anzahl der zurückgelegten Umdrehungen auch die jeweilige Höhe der Drehzahl eingeht und der damit ein Maß für diie Beanspruchung der Maschine darstellt.The object of the invention is to design a revolution counter for such machines in such a way that that in its count, in addition to the number of revolutions covered, the respective amount of the Speed is included and thus represents a measure of the stress on the machine.
Diese Aufgabe wird durch die im kennzeichnenden Teil des Patentanspruchs I angegebenen Merkmale gelöst. This object is achieved by the features specified in the characterizing part of claim I.
Das Zählwerk des Gerätes zeigt damit einen Wert an, der nicht nur in einem bestimmten Verhältnis zu der Anzahl der durchgeführten Umdrehungen einer Maschinenwelle steht, sundern der zusätzlich von der je-The counter of the device thus shows a value that is not only in a certain ratio to the The number of revolutions performed by a machine shaft, and the additional number of revolutions
