Description
<Desc/Clms Page number 1>
Die Erfindung bezieht sich auf eine Einrichtung zur axialen Sicherung eines Lagers auf einer Achse oder Welle, insbesondere für die Lager der Rollen von Gurtenförderern auf ihren Achsen, unter
Verwendung eines Stützringes, dessen vom Lager abgewendeter Rand in einer Kerbe oder Ringnut der
Achse eingestaucht ist. Derartige Einrichtungen sind beispielsweise in der GB-PS Nr. 1410123 beschrieben.
Auch die DE-OS 2313234 hat eine solche Einrichtung zum Gegenstand, wobei den bekannten Ausbildungen der Nachteil gemeinsam ist, dass durch die Stützringe Staub in die Lager eindringen konnte und daher gesonderte Abdichtungsmassnahmen ergriffen werden mussten.
Die Erfindung zielt nun darauf ab, eine besonders einfache Ausbildung zu schaffen, welche die Nachteile der bekannten Ausbildungen vermeidet, und besteht im wesentlichen darin, dass der Stützring als das Lager abdichtendes Dichtungselement ausgebildet ist. Auf diese Weise wird eine besonders einfache Art der Sicherung eines Lagers gegen axiale Verschiebung geschaffen, welche gleichzeitig das Eindringen von Staub in die Lager verhindert. Der Stützring erfüllt hiebei selbst die Dichtungsfunktion und es kann auf die Verwendung eines gesonderten Dichtungselementes verzichtet werden.
Gemäss einer bevorzugten Ausbildung der erfindungsgemässen Einrichtung ist die Ausbildung so getroffen, dass das Dichtungselement als Labyrinthdichtung, deren Labyrinthspalte sich koaxial zur Welle erstrecken, ausgebildet ist und dass der den den kleinsten Durchmesser aufweisenden Labyrinthspalt innen begrenzende Ringsteg des mit der Achse verbundenen Teiles der Labyrinthdichtung in die Ringnut der Welle eingestaucht ist. Diese Ausführung ermöglicht eine besonders billige Herstellung der erfindungsgemässen Einrichtung, welche hohe Betriebssicherheit aufweist. Die Ausbildung der Dichtung als Labyrinthdichtung hat hiebei den Vorteil, dass der Verschleiss der gegeneinander verdrehbaren Teile auf ein Minimum reduziert wird.
In der Zeichnung ist die Erfindung an Hand eines Ausführungsbeispieles schematisch erläutert.
Die Zeichnung zeigt einen Axialschnitt durch den die Lagerung aufweisenden Teil einer Gurtrolle eines Gurtförderers.
Die Rolle-l-ist unter Vermittlung eines Lagers --2-- auf einer Achse --3-- gelagert. Der innere Lagerring --7-- ist durch einen Stützring --4-- in der Achsrichtung gegen Verschiebung gesichert. --5-ist eine Ringnut in der Achse --3--, welche einen sägezahnartigen Querschnitt aufweist und durch eine senkrecht zur Achse stehende Flanke --6-- begrenzt ist. In diese Ringnut --5-- ist der vom Lager --2-abgewendete Rand --8-- des Stützringes --4-- eingestaucht. Der Stützring --4-- besteht aus Metall, so dass diese Einstauchung leicht durchgeführt werden kann.
- ist eine Lippendichtung, welche an der Rolle --1-- durch Schrauben oder Nieten befestigt ist.
Der Dichtungskörper --10-- bildet mit dem Dichtungselement --11-- des Stützringes --4-- zusammen eine Labyrinthdichtung. --12-- ist gleichfalls ein Dichtungsring.
PATENTANSPRÜCHE :
1. Einrichtung zur axialen Sicherung eines Lagers auf einer Achse oder Welle, insbesondere für die Lager der Rollen von Gurtenförderern auf ihren Achsen, unter Verwendung eines Stützringes, dessen vom Lager abgewendeter Rand in eine Kerbe oder Ringnut der Achse eingestaucht ist, dadurch gekennzeichnet, dass der Stützring (4) als das Lager (2) abdichtendes Dichtungselement (11) ausgebildet ist.

The invention relates to a device for axially securing a bearing on an axle or shaft, in particular for the bearings of the rollers of belt conveyors on their axles, below
Use of a support ring whose edge facing away from the bearing in a notch or ring groove of the
Axis is indented. Such devices are described, for example, in GB-PS No. 1410123.
DE-OS 2313234 also has such a device as its subject matter, the known designs having the disadvantage that dust could penetrate the bearings through the support rings and therefore separate sealing measures had to be taken.
The aim of the invention is to create a particularly simple design which avoids the disadvantages of the known designs, and essentially consists in the support ring being designed as a sealing element which seals the bearing. In this way, a particularly simple way of securing a bearing against axial displacement is created, which at the same time prevents dust from entering the bearing. The support ring itself fulfills the sealing function and the use of a separate sealing element can be dispensed with.
According to a preferred design of the device according to the invention, the design is such that the sealing element is designed as a labyrinth seal, the labyrinth gaps of which extend coaxially to the shaft, and that the annular web of the part of the labyrinth seal connected to the axis, which internally delimits the labyrinth gap with the smallest diameter, is in the ring groove of the shaft is indented. This design enables the device according to the invention to be manufactured particularly cheaply, which has high operational reliability. The design of the seal as a labyrinth seal has the advantage that the wear and tear on the parts that can rotate relative to one another is reduced to a minimum.
The invention is illustrated schematically in the drawing using an exemplary embodiment.
The drawing shows an axial section through the bearing part of a belt roller of a belt conveyor.
The roller-l-is stored on an axis --3-- through the intermediary of a bearing --2--. The inner bearing ring --7-- is secured against displacement in the axial direction by a support ring --4--. --5- is an annular groove in the axis --3--, which has a sawtooth-like cross section and is delimited by a flank --6-- perpendicular to the axis. The edge --8-- of the support ring --4-- facing away from the bearing --2- is inserted into this annular groove --5--. The support ring --4-- is made of metal so that this indentation can be carried out easily.
- is a lip seal, which is attached to the roller --1-- with screws or rivets.
The sealing body --10-- and the sealing element --11-- of the support ring --4-- together form a labyrinth seal. --12-- is also a sealing ring.
PATENT CLAIMS:
1. Device for axially securing a bearing on an axle or shaft, in particular for the bearings of the rollers of belt conveyors on their axles, using a support ring whose edge facing away from the bearing is indented into a notch or annular groove of the axle, characterized in that the support ring (4) is designed as a sealing element (11) sealing the bearing (2).
