Description

Eei Zahnradgetrieben aller Art kommt es häufig vor, daß durch Unaufmerksamkeit in der Wartung oder durch technische Störungen, z. B Verstopfung des Olstandglases, zuwenig Öl in dem Gehäuse ist und infolgedessen das Getriebe vorzeitig abgenutzt lvird.4Um diese Gefahr zu beseitigen. soll nach der Erfindung eine selbsttätige Warnvorrichtung an den Flüssigkeitsbehälter des Getriebes oder z.B. auch an die Wanne eines Älotors angeschlossen werden. Eei gear drives of all kinds, it often happens that by inattention in maintenance or due to technical malfunctions, e.g. B clogging of the oil level glass, There is not enough oil in the housing and as a result the gearbox wears out prematurely lvird.4To eliminate this danger. should be automatic according to the invention Warning device on the fluid container of the gearbox or e.g. also on the An otor's tub can be connected.

Vorrichtungen, die abhängig von der Höhe eines Flüssigkeitsstandes gewisse andere Wirkungen anslösen, sind in großer Zahl an sich bekannt. Es können mechanische Vorrichtungen sein, die mit einem Schwimmer arbeiten, sie können auch hydraulisch bzw. pneumatisch wirken, indem ein Standglas oder WIanometerrohr je nach der Höhe des Flüssigkeitsstandes unter Druck gesetzt wird.Devices that depend on the height of a liquid level solving certain other effects are known per se in large numbers. It can mechanical devices that work with a float, they can too act hydraulically or pneumatically by placing a stand glass or WIanometer tube each is pressurized according to the height of the liquid level.

Außerdem gibt es elektrische Sontakteinrichtungen, die bei leitenden Flüssigkeiten ulnmittelbar durch die Flüssigkeit selbst geschlossen werden.There are also electrical contact devices that are used when conducting Liquids are closed immediately by the liquid itself.

Entsprechend der Vorrichtung am Flüssigkeitsbehälter kann das Warnsignal auch die verschiedensten bekannten Ausführungen haben. Es kann ein Zeiger sein, der auf eine der obengenannten Weisen bewegt wird, oder auch ein Licht- oder Lautsignal. Mit diesem Signal in Verbindung oder an dessen Stelle kann auch eine selbsttätige Abschaltvorrichtung für die zu schützende Maschine verwendet werden, z.B. ein selbsttätiger elektrischer Stromunterbrecher. According to the device on the liquid container, the warning signal also have a wide variety of known designs. It can be a pointer which is moved in one of the above-mentioned ways, or a light or sound signal. In conjunction with this signal or in its place, an automatic Disconnection device can be used for the machine to be protected, e.g. an automatic electric circuit breaker.

In der Zeichnung sind eine Anzahl von Ausfuhrungsbeispielen nach dem Erfindungsgedanken angegeben, die sich sämtlich auf den Flüssigkeitsstand in einem Getriebebehälter beziehen. In the drawing are a number of exemplary embodiments according to indicated the idea of the invention, all of which relate to the liquid level in refer to a gearbox.

Fig. I zeigt in dem Behälter reinen Schwimmer, der über einen Hebel 3 den elektrischen Kontakt 4, 5 betätigt. Fig. I shows pure float in the container, which has a lever 3 the electrical contact 4, 5 actuated.

Fig. 2 zeigt dieselbe Einrichtung wie Fig I bei abgesunkenem Flüssigkeitsstand und geschlossenem Kontakt. FIG. 2 shows the same device as FIG. 1 when the liquid level has dropped and closed contact.

Fig. 3 gilt für den Fall, daß die Flüssigkeit im Behälter elektrisch leitend ist und zeigt demgemäß in dem Behälter I zwei in die Flüssigkeit eintauchende elektrische Kontaktstäbe 6, 7. Fig. 3 applies in the event that the liquid in the container is electrical is conductive and accordingly shows in the container I two immersed in the liquid electrical contact rods 6, 7.

In Fig. 4 wird an demselben Beispiel wie in Fig. 3 die Unterbrechung des Kontaktes bei abgesunkenem Flüssigkeitsspiegel dargestellt. In FIG. 4, the same example as in FIG. 3 shows the interruption of the contact when the liquid level has dropped.

Die Fig. 5 und 6 zeigen eine Vorrichtung ähnlich den Fig. I und 2, jedoch mit dem Unterschied, daß in einem getrennt neben dem Gehäuse I angebauten ZylinderS ein Tauchkolben 9 auf der Flüssigkeit schwimmt und bei hohem Flüssigkeitsstand elektrische Kontakte Io, II durch ein Kontaktstück r2 schließt bzw. nach Fig. 6 beim Absinken der Flüssigkeit öffnet. FIGS. 5 and 6 show a device similar to FIGS. I and 2, but with the difference that in a separately grown next to the housing I. CylinderS a plunger 9 floats on the liquid and when the liquid level is high electrical contacts Io, II are closed by a contact piece r2 or according to FIG. 6 opens when the liquid sinks.
