Description
Vorrichtung zum Sichern von Lagern und anderen- beweglichen IVIaschinenteilen . gegen- Heißlauf. Gegenstand der Erfindung ist eine weitere Ausbildung der durch das Patent 311909 geschützten 'Vorrichtung zum Sichern von Lagern und anderen beweglichen Maschinenteilen gegen. Heißlauf. Die bisher bekannten Vorrichtungen zum Kühlen von Lagern bei Heißlauf bieten keine Gewähr für die Ver-, hütung des Heißlaufs, da die kritische Temperatur nicht rechtzeitig angezeigt wird.Device for securing bearings and other movable machine parts . against overheating. The invention is a further embodiment of the by the patent 311909 protected 'device for securing bearings and other movable Machine parts against. Overheating. The previously known devices for cooling Storage when overheating does not guarantee the prevention of overheating, as the critical temperature is not displayed in time.
Gemäß vorliegender Erfindung wird zugleich mit der in Tätigkeit tretenden Kühlung dem Diensttuenden die Gefahr angezeigt und in Fällen, wo eine sofortige Stillsetzung des gefährdeten Maschinenteils nicht möglich ist (z: B. bei der Eisenbahn), durch das selbsttätig zufließende Kühlmittel ein weiteres Erhitzen des gefährdeten Lagers oder sonstigen Maschinenteils vorläufig verhindert.According to the present invention, it is simultaneously with the entering into activity Cooling indicated the danger to the duty worker and in cases where an immediate Shutting down the endangered machine part is not possible (e.g. on the railroad), due to the automatically flowing coolant further heating of the endangered Bearing or other machine part temporarily prevented.
In der Zeichnung ist eine solche Sicherung von Lagern in Verbindung mit selbsttätiger Kühlung dargestellt, und zwar ist die Schmelzpatrone, entgegen der in der Hauptpatentschrift dargestellten wagerechten Lage, senkrecht angeordnet. An Stelle der getrennten Anordnung der Schmelzpfropfen und der Zugstange ist bei dieser Ausführung beides vereinigt, so daß die Zugstange des Kolbens b in den Schmelzpfropfen c hineingeschraubt ist. Letzterer ist in seinem unteren Ende mit Gewinde in den unteren Teil des Gehäuses a eingeschraubt und hat eine Verjüngung 1, über der er kolbenartig ausgebildet ist und hierdurch die Kammer k mit Kühlmasse gegen die Kanäle g abschließt. . Die Wirkungsweise ist folgende: Sobald das Lager die kritische Temperatur erreicht; schmilzt der Pfropfen c in seinem kleinsten Querschnitt bei L ab und die Kolbenstange b wird durch die Feder h nach oben geschnellt, wodurch die Kammer k mit den Kanälen g in 'Verbindung gebracht wird und die Kühlmasse Zutritt nach dem Lager.erhält. Der Kälben b schließt aber auch gleichzeitig durch Verbindung der mittels der Isolierungen e in den durch die Schrauben f befestigten Dekkel i eingesetzten Klemmen d einen elektrischen Stromkreis und löst damit die Alarmvorrichtung aus.In the drawing, such a securing of bearings in connection with automatic cooling is shown, namely the melt cartridge, contrary to the horizontal position shown in the main patent, is arranged vertically. Instead of the separate arrangement of the fusible plug and the pull rod, both are combined in this embodiment, so that the pull rod of the piston b is screwed into the fusible plug c. The latter is screwed into the lower part of the housing a with a thread at its lower end and has a taper 1 over which it is designed like a piston and thereby closes the chamber k with cooling compound against the channels g. . The mode of operation is as follows: As soon as the bearing reaches the critical temperature; the plug c melts in its smallest cross-section at L and the piston rod b is snapped upwards by the spring h, whereby the chamber k is brought into communication with the channels g and the cooling mass receives access to the bearing. The calf b also closes an electrical circuit at the same time by connecting the terminals d inserted into the cover i fastened by the screws f by means of the insulation e and thus triggers the alarm device.
