Abstract

In a roller conveyor the rollers are carried on shafts via ball bearings. The bearings are sealed against the leakage of grease by a labyrinth seal and a lip seal. The lip seal has a central synthetic portion forming the lip which runs on a cylindrical extension of one of the labyrinth seals and is retained by a top hat pressing interposed between the seal periphery and the roller. The top of the top hat section has a central aperture with a rolled lip edge which cooperates with a corresponding lip on a further sheet metal pressing pushed over the end of the shaft to protect the assembly from abrasive particles.

Description

Vorrichtung zum Abdichten von Wälzlagern, insbesondere für Transportbandrollen Die Erfindung betrifft eine Vorrichtung zum Abdichten von Wälzlagern, insbesondere für Transportbandrollen, bestehend aus in wechselnder Folge hintereinander angeordneten Einzeldichtungen verschiedener Bauart.Device for sealing roller bearings, in particular for conveyor belt rollers The invention relates to a device for sealing roller bearings, in particular for conveyor belt rolls, consisting of arranged one behind the other in alternating order Individual seals of various types.

Es ist eine Vorrichtung zum Abdichten von Wälzlagern, insbesondere für Transportbandrollen bekannt, die aus mehreren in axialer Richtung hintereinander angeordneten Spaltdichtungen mit dazwischen vorgesehenen Beruhigungs- und Fettkammern besteht. (DT-OS 2 024 448) Diese Vorrichtung erfüllt zwar ihren Zweck, das Wälzlager vor eindringendem Schmutz zu schützen, recht gut. Nachteilig ist jedoch, daß ihre einzelnen Teile jedes für sich in den Lagerhalter eingebaut werden muß, was sich ungünstig auf die Montagezeiten auswirkt Aufgabe der vorliegenden Erfindung ist es demzufolge eine Vorrichtung zum Abdichten von Wälzlagern, insbesondere für Transportbandrollen zu konzipieren, welche die Lager in möglichst hohem Maße vor Schmutz schützt, wobei der Reibungswiderstand so klein wie möglich, die Dauerfestigkeit gegen Abrieb aber möglichst groß und die Montagezeiten zum Einbau in die Transportbandrolle zum Zwecke der Einsparung von Lohnkosten so weit wie möglich reduziert werden sollten.It is a device for sealing rolling bearings, in particular known for conveyor belt rollers, which consist of several in the axial direction one behind the other arranged gap seals with calming and grease chambers provided in between consists. (DT-OS 2 024 448) Although this device fulfills its purpose, the roller bearing To protect against penetrating dirt, quite good. The disadvantage, however, is that their individual parts each must be installed in the warehouse keeper, which is has an unfavorable effect on the assembly times It is therefore a device for sealing roller bearings, in particular for conveyor belt rollers to design that protects the bearings as much as possible from dirt, whereby the frictional resistance as small as possible, but the fatigue strength against abrasion As long as possible and the assembly times for installation in the conveyor belt roll for the purpose the saving of labor costs should be reduced as much as possible.

Diese Aufgabe wurde gelöst durch die erfindungsgemäße Vorrichtung gemäß den Kennzeichen der Patentansprüche.This object was achieved by the device according to the invention according to the characteristics of the claims.

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß die Vorrichtung als komplette Einheit in zusammengebautem Zustand nur noch in den Lagerhalter eingepreßt zu werden braucht, was die Lagerhaltung und die Montagekosten gunstig beeinflußt; daß die Bautiefe gering gehalten werden kann und daß durch die eingebaute Lippendichtung ein besonders hoher Dichtungseffekt erreicht wird, wobei durch die Verwendung des mit kleinsten mineralischen, Karbid- oder Glasperlchen durchsetzten Werkstoffes der Lippendichtung und/oder des korrespondierenden Teiles der Labyrinthdichtung sowohl eine hohe Abriebfestigkeit als auch ein geringer Reibungskoeffizient erreicht und dadurch u.a. auch der bei allen Bandrollen störende Anlaufwiderstand erheblich reduziert wird Die Zeichnung erläutert den Erfindungsgegenstand an einem Ausführungsbeispiel.The advantages achieved with the invention are in particular: that the device as a complete unit in the assembled state only in the warehouse keeper needs to be pressed in, what the storage and the assembly costs favorably influenced; that the overall depth can be kept small and that by the built-in lip seal a particularly high sealing effect is achieved, whereby by using the smallest mineral, carbide or glass beads penetrated material of the lip seal and / or the corresponding part the labyrinth seal has both high abrasion resistance and a low coefficient of friction and thereby also the start-up resistance, which is a disruptive factor in all belt rollers is significantly reduced The drawing explains the subject matter of the invention on one Embodiment.

Der in seinen Außenmaßen auf den Lagerhalter 1 abgestimmte Lagerhalterdeckel 2 hintergreift mit seinem nach außen weisenden inneren Kragen 3 die im Querschnitt L-förmige Achsabdichtung 4 und bildet so mit ihr die erste Spaltdichtung 5.The bearing holder cover, which is matched to the bearing holder 1 in terms of its external dimensions 2 engages behind with its outwardly facing inner collar 3 in cross section L-shaped axle seal 4 and thus forms the first gap seal 5 with it.

Diese beiden Teile bilden dann zusammen mit der auf dem hülsenförmigen Steg 6 des vorderen Labyrinthteils 7 schleifenden Lippendichtung 8 einen Beruhigungsraum 9, in dem sich der von außen eindringende Sch@utz absetzt. Die Lippendichtung 8 ist mit Preßsitz in dem Lagerhalterdeckel 2 gehalten, und ihr elastischer Werkstoff ist gegebenenfalls zur Reduzierung des Reibungskoeffizienten und zur Erhöhung der Abriebfestigkeit mit staubkorngroßen Perlchen aus Mineralien, Karbid, Glas oder dgl. durchsetzt. Selbstverständlich kann das Gleiche auch/oder bei dem hülsenförmigen Kragen 6 des Labyrinthteils 7, der die Achsabdichtung 4 kraftschlüssig übergreift, der Fall sein.These two parts then form together with the one on the sleeve-shaped Web 6 of the front labyrinth part 7 rubbing lip seal 8 a calming space 9, in which the protection penetrating from the outside is deposited. The lip seal 8 is held with a press fit in the bearing holder cover 2, and its elastic material is if necessary to reduce the coefficient of friction and to increase the Abrasion resistance with dust-grain-sized pearls made of minerals, carbide, glass or like. interspersed. Of course, the same can also / or in the case of the sleeve-shaped Collar 6 of the labyrinth part 7, which engages over the axle seal 4 in a non-positive manner, be the case.

Zwischen der Lippendichtung 8 und dem sich anschließenden Labyrinthteil 7 ist eine Fettkammer 10 angeordnet. Das hintere Labyrinthteil 11, das sich gegen das Wälzlager 12 anlegt ist mit seinem äußeren Kragen 15 in den Lagerhalterdeckel 2 eingepreßt.Between the lip seal 8 and the adjoining labyrinth part 7 a grease chamber 10 is arranged. The rear labyrinth part 11, which is against the roller bearing 12 is applied with its outer collar 15 in the bearing holder cover 2 pressed in.

Auf diese oben geschilderte Weise sind alle Einzelteile der erfindungsgemäßen Dichtungsvorrichtung gegeneinander lösbar gehalten, so daß sie zusammengebaut eine komplette einbaufertige Einheit bilden.In this manner described above, all individual parts are of the invention Sealing device held against each other releasably so that they assembled a Form a complete unit ready for installation.
