Description

Im, Hauptpatent933 595 wird eine Axial Flüssigkeitsdi.chtung behandelt, bei der auf einer mit der Welle rotierenden; metallischen ölabweisscheibe ein Dichtring aus Gußb@ronze oder einem, anderen geeigneten Material axial schleift, der in einen fest am Gummigehäuse sitzenden ölfesten Gummiringbalg einvulkanisiert ist.In, main patent 933 595 an axial liquid seal is treated, at the one rotating with the shaft; metallic oil-repellent washer a sealing ring Made of cast bronze or some other suitable material axially grinds into a is vulcanized into the oil-resistant rubber ring bellows, which is firmly seated on the rubber housing.

Systematische Untersuchungen haben nun ergeben, daß die Luft in dem, Raum zwischen Gehäuse und Gummibalg eine gewisse Druckanreicherung erfährt, die das Vordringen von Öltröpfchen gegen den Gummibalg erschwert. Eine Verhärtung des Gummis durch aktive 051e, wie sie bei den bisher verwendeten radialen Dichtringen häufig vorkamen, wird dadurch vermieden.Systematic investigations have now shown that the air in the The space between the housing and the rubber bellows experiences a certain pressure build-up that the penetration of oil droplets against the rubber bellows is difficult. A hardening of the Rubbers through active 051e, as they are with the radial sealing rings used up to now frequently occurred is avoided.

Erfindungsgemäß wird durch Anbringung von Rippen oder Nuten an der ölabweisscheibe deren. Pumpenwirkung merklich erhöht und damit in dem den Gummibalg umgebenden Raum ein Druckluftpolster erzeugt, das für die Fernhaltung des Sprühöls von der Gummidichtung vom, maßgebender' Bedeutung ist.According to the invention by attaching ribs or grooves to the oil deflector whose. Pump effect noticeably increased and thus in the rubber bellows surrounding space creates a cushion of compressed air, which is used to keep the spray oil away of the rubber seal is of "decisive" importance.

Die im Hauptpatent gezeigten Schenkel des. Dichtringes werden damit überflüssig und der Gummibalg einfacher und kürzer in seiner Baulänge. Auch die endlose Wendelfeder wird eingespart und die axiale Vorspannung des Gummibalges durch eingepreßte Gummirippen erhöht.The legs of the sealing ring shown in the main patent are thus superfluous and the rubber bellows simpler and shorter in its overall length. Also the Endless helical springs are saved and the axial preload of the rubber bellows is reduced Pressed-in rubber ribs increased.

Bei der . axialen Beanspruchung des Dichtringes werden diese Rippen auf Zug beansprucht. Da die Rippen vollkommen ölgeschützt angeordnet sind, bleibt auf jeden Fall die Federspannung der Dichtung erhalten.In the . axial stress on the sealing ring are these ribs stressed on train. Since the ribs are arranged completely oil-protected, remains In any case, the spring tension of the seal is preserved.

Der Erfindungsgegenstand ist in der Zeichnung in einer Ausführungsform beispielsweise dargestellt. Die ölabweisscheibe i ist mit Radialnuten 2 versehen, die im Raume 7 einen Luftdruckanstieg bewirken. Gegen die Scheibe i drückt, wie beim Gegenstand des Hauptpatents, ein metallischer Dichtring 3 vom. rechteckigem Querschnitt, der in einem Gummiringbalg ¢ einvulkanisiert ist. Dieser Gummibalg q. ist mit seinem zweilippigen. Ende auf einen fest am Gehäuse sitzenden Ringnocken 5 aufgeschoben.The subject matter of the invention is shown in the drawing in one embodiment, for example. The oil-repellent disk i is provided with radial grooves 2 which cause an increase in air pressure in space 7. A metallic sealing ring 3 from the presses against the disk i, as in the subject of the main patent. rectangular cross-section, which is vulcanized into a rubber ring bellows ¢. This rubber bellows q. is with its two-lipped. The end is pushed onto a ring cam 5 that is firmly seated on the housing.

Zur Erhöhung der axialen Vorspannung des Gummibalges ¢ sind zwischen dessen Befestigungslippen und dem Dichtring 2 mehrere Gummistege 6 eingepreßt.To increase the axial preload of the rubber bellows ¢ are between the fastening lips of which and the sealing ring 2 are pressed in several rubber webs 6.
