Description
Zur Abdichtung in staubhaltiger Luft umlaufender Wellen gegen ihre Läger verwendet man Stopf-Büchsen mit nach der Staubseite zu trockenen Packungen, da bei fetthaltigen Packungen der hinzutretende Staub Verkrustungen zur Folge hat, welche die Nachgiebigkeit und Dichtungsfähigkeit der Packung aufheben und zu Anfressungen der Welle fuhren. -Die trockenen Packungen andererseits haben eine verhältnismäßig kurze Lebensdauer. Ihre häufigere Erneuerung stellt unerwünschte Anforderungen an die Wartung der Maschinen.For sealing shafts rotating in dusty air against their Stuffing boxes are used with packs that are too dry on the dust side, since the dust that is added in the case of greasy packs results in incrustations, which cancel out the flexibility and sealability of the packing and cause pitting the wave drove. -The dry packs, on the other hand, have a proportionate short lifespan. Their more frequent renewal makes undesirable demands the maintenance of the machines.
Erfindungsgemäiß@ werden diese Nachteile vermieden durch die Anordnung eines Grundringes in der Stopfbüchse, .der als Fettverteilüngsring ausgebildet ist. Hierdurch gelingt es, eine schützende Fettschicht vor die Packung zu legen. Durch Nachdrücken von Fett werden etwa sich durch Staubzutritt bilden-de Verkrustungen-nach außen gestoßen. Die Packung erhält auf diese Weise ebenfalls Fett, ohne dabei ,der Verschmutzung zu unterliegen; wodurch eine beträchtlich höhere Laufzeit der Packung und einfachere Wartung erzielt werden.According to the invention, these disadvantages are avoided by the arrangement a base ring in the stuffing box, which is designed as a fat distribution ring. This makes it possible to put a protective layer of fat in front of the pack. By For example, pressing in of fat will result in the formation of encrustations due to the ingress of dust bumped on the outside. The pack also receives fat in this way, without the Subject to pollution; thus a considerably longer running time of the pack and easier maintenance can be achieved.
In weiterer Ausbildung der Erfindung wird am Ende der Stopfbüchse noch eine Labyrinthdichtung ausgebildet, durch welche dass austretende Fett hindurch mußt Hierdurchwird die schützendeWirkung des Fettes erhöht und bei entsprechender Ausbildung einem Herausschleudern des Fettes bei großen Umlaufzahlen der Welle vorgebeugt.In a further embodiment of the invention, the stuffing box is at the end Another labyrinth seal is formed through which the leaking fat can pass Must This increases the protective effect of the fat and with the appropriate Training prevents the grease from being thrown out when the shaft rotates at large numbers.
In der Zeichnung ist ein Ausführungsbeispiel schaubildlich, erläutert.An exemplary embodiment is graphically explained in the drawing.
Das «Gehäuse i einer Aufgabevorrichtung 'für pneumatische Förderanlagen ist mit einer Durchtrittsöffnung 2 für die Welle 3 der Wirbelschnecke versehen. In dieser Öffnung z- ist ein Grundring 4 angeordnet, der als Fettverteilungsring ausgebildet ist mit zwei durch Bohrungen 5 verbundenen Ringnuten 6.'; .6". Der äußeren Ringnute wird durch Kanäle 7 in den Gehäusewandungen von außen in an sich bekannter Weise Fett zugedrückt.The "housing in a feeding device" for pneumatic conveying systems is provided with a passage opening 2 for the shaft 3 of the vortex screw. In this opening z a base ring 4 is arranged, which acts as a fat distribution ring is designed with two annular grooves 6 'connected by bores 5; .6 ". The outer Annular grooves are known per se from the outside through channels 7 in the housing walls Wise fat squeezed.
Gegen den Grundring legt sich die innere Packung 8, an die sich der bekannte Kühlring g mit Luftein- und -austrittsöffnungen io und ii sowie die äußere Packung i2 mit in ihr liegendem Fettverteilungsring 13 und Preßring 14 anschließen.The inner packing 8, to which the known cooling ring g with air inlet and outlet openings io and ii and the outer one Connect pack i2 with grease distribution ring 13 and press ring 14 inside.
Vor dem Grundring ist auf der Welle ein Spritzrind 15 befestigt, der zusammen mit dem an das Gehäuse i geschraubten Gegenring 16 ein Labyrinth für das austretende Fett bildet.In front of the base ring, a cowl 15 is attached to the shaft, the together with the counter ring 16 screwed to the housing i a labyrinth for the leaking fat forms.
Der Pre&ing 14 wirkt somit sowohl gegen die innere Packung 8 als auch gegen die äußere Packung 12 und 13. The pre & ing 14 thus acts both against the inner packing 8 and against the outer packing 12 and 13.
