Description

Speicherschwungrad Die Erfindung betrifft ein Speioherschwungrad insbesondere fUr Notstromaggregate, das in ausgegossenen Gleitlagern gelagert ist Rotierende Speicherschwungräder besitzen eine kinetische Energie, die bei größeren Rädern und höheren Drehgahlen, wie aie 1. B. bei Verwendung in Sofortreserve- oder Schnellboroitschaftsaggregsten eingesetzt werden, eine solche Größe erreicht, daß ein schnelles Abbremsen tu Falle eines Lagerschadens nicht mehr möglich ist. Das ist der Ball, wenn die Lagerung des Speicherschwungrades derart funktionsuntüchtig geworden ist, daß ein normales Auslauien der Anlage wegen der dafür notwendigen Zeit nicht mehr möglich ist. Selbat durch eine eventuelle vorhandene Lagertemperaturüberwachung können die Folgeschäden nicht vermieden werden, da der normale Ab- @ bretuavorgang bzw. der Auslauf der Anlage twar automatisch unter Abschaltung der elektrischen Verbraucher einsetzt, aich dann aber Je nach Drehzahl und Größe des Rades über einen mehr oder weniger langen Zeitraum erstreckt, während dem -die Speicherschwungradlager restlos zerstört werden können und das Speicherschwungrad Beschädigungen größten Ausmaßes an der Anlage und an umgebenden Teilen anrichten kann. Storage flywheel The invention relates to a storage flywheel in particular for emergency power generators, which are mounted in poured-out slide bearings Rotating storage flywheels have a kinetic energy that is greater than that of larger ones Wheels and higher speeds, as aie 1. B. when used in immediate reserve or Schnellboroitschaftsaggregsten are used, reached such a size that rapid braking is no longer possible in the event of bearing damage. That is the ball when the storage of the storage flywheel is so inoperable has become that a normal leaching of the system because of the necessary Time is no longer possible. This is due to any existing storage temperature monitoring the consequential damage cannot be avoided, since the normal abortion process or the shutdown of the system twar automatically with the electrical shutdown Consumer starts, but then depending on the speed and size of the wheel via one more or less long period of time during which the storage flywheel bearings can be completely destroyed and damage the storage flywheel greatest Extent can cause damage to the system and surrounding parts.

Der erfindung liegt die Aufgabe zugrunde, mit einfachen Hitteln eine selbsttätig wirkende Vorrichtung zu schaffen, durch die das Speicherschwungrad bei einen Lagerschaden in kurser Zeit abgebremst wird. Sie wird erfindungsgenäß bei einem Jotstromaggregat der eingangs beschriebenen Art dadurch gelöst, daß au Umfang des Speicherschwungrades unterhalb der horizontalin ebene durch die lagerachse Bremsbscken in einem so g»-ringen Abstand von der Umfangefläche des Speicherschwungrsdes angeordnet sind, daß das Speicherschwungrad bei Absenkung um höchstens der Stärke des Lagerausgusses an den Brensbacken zur Anlage gelangt.The invention is based on the task of a simple Hittel to create an automatically acting device through which the storage flywheel at a bearing damage is slowed down in a short time. It is according to the invention a Jotstromaggregat of the type described above solved in that au scope of the storage flywheel below the horizontal in level through the bearing axis brake pads arranged at such a large distance from the circumferential surface of the storage swing gear are that the storage flywheel when lowered by at most the thickness of the bearing spout reaches the system on the baking jaws.

Bei Lagerschäden wird die lagertemperatur so hoch, daß der aus Lagermetall bestehende Lagerausguß von einigen Millimetern Stärke ausläuft. Das Speicherschwungrad senkt sich infolgedessen um einen geringen Betrag ab und kommt an den Bremsbacken zur Anlage, von denen es unter Einwirkung des Eigengewichtes abgebremst wird, bevor weitere Folgeschäden auftreten können. Um den Abstand zwischen den Browbacken und dem Spoichorschwungrad möglichst klein halten zu können, iet es zweckmäßig, daß die Bremsbacken einstellbar sind. Ferner ist es vorteilhaft, daß der Abstand iwisohen den Halterungen der Bremsbacken und den Umfang des Speicherschwungrades in Drehrichtung des Speicherschwungrades abnimmt. Man erreicht dadurch, daß sich die Bremsbacken im Notfall nicht aus ihren Halterungen lösen können, selbst wenn ihre Befestigungselemente der Belastung nicht standhalten.In the event of storage damage, the storage temperature is so high that the one made of bearing metal Existing bearing spout of a few millimeters thick runs out. The storage flywheel As a result, it lowers itself by a small amount and comes into contact with the brake shoes to the system, of which it is under the influence of the Dead weight braked before further consequential damage can occur. About the distance between the brows and to be able to keep the spoiler flywheel as small as possible, it makes sense to that the brake shoes are adjustable. It is also advantageous that the distance iwisohen the brackets of the brake shoes and the scope of the storage flywheel decreases in the direction of rotation of the storage flywheel. One achieves that the brake shoes cannot be released from their holders in an emergency, even if their fasteners cannot withstand the load.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung schematisch dargestellt.An exemplary embodiment of the invention is shown schematically in the drawing shown.

Mit 1 ist ein Speicherschwungrad bezeichnet, das in ausgegossenen Gleitlagern 2 gelagert ist. Der Iaugerausguß 3 der Gleitlager 2 hat eine Stärke 4. Unterhalb der horizontalen Ebene 5 durch die lagerachse sind Bremabacken 6 mit Reibbelegen 7 in einen so geringen Abstand 8 von der Umfangsfläche 9 des Speicherschwungrades 1 angeordnet, daß des Speicherschwungrad 1 bei Absenkung um höchstens der Stärke 4 des Lagerausgusses an den Reibbelegen 7 der Bremsbacken 6 sur Anlage gelangt. Die Bremsbacken 6 sind lit Relterungen 10 eines Grundgestells 11 fest verbunden. Dabei nimmt der Abstand zwischen den Halterungen 10 der Bremsbacken 6 und den Umfang 9 des Speicherschwungrades 1 in Drehrichtung 12 des Speicherschwungrades 1 ab. Den Abstand 8 der Reibbelege 7 der Breoobacken 6 vom Umfang 9 des Speicherschwungrades 1 iet durch Stellschrauben 19 einstellbar.1 with a storage flywheel is referred to, which is poured in Plain bearings 2 is mounted. The Iaugerausguß 3 of the plain bearing 2 has a thickness 4. Below the horizontal plane 5 through the bearing axis are brake jaws 6 with Friction linings 7 at such a small distance 8 from the circumferential surface 9 of the storage flywheel 1 arranged that the storage flywheel 1 when lowering by at most the strength 4 des Lagerausgusses on the friction linings 7 of the brake shoes 6 sur Plant arrives. The brake shoes 6 are lit braces 10 of a base frame 11 firmly connected. The distance between the brackets 10 of the brake shoes increases 6 and the circumference 9 of the storage flywheel 1 in the direction of rotation 12 of the storage flywheel 1 from. The distance 8 of the friction linings 7 of the Breoobacken 6 from the circumference 9 of the storage flywheel 1 iet adjustable by adjusting screws 19.
