Description

Staubschutzdeckel mit Nachschmieröffnung für Tragrollen Die Erfindung bezieht sich auf Staubschutzdeckel mit einer Schmieröffnung als Teil einer Labyrinthdichtung eines Tragrollenwälzlagers, das einen auf der feststehenden Rollenachse durch Verschrauben feststellbaren Lagerkonus als inneren Laufring aufweist. Die Rollen sind üblicherweise über Kugellager auf einer durchgehenden Achse oder auch auf zwei Achszapfen gelagert. Die Lager sind durch feststehende oder auch umlaufende Staubdeckel in Verbindung mit einem Dichtungsring oder einer Labyrinthdichtung gegen Eindringen von Staub geschützt. Zum Nachschmieren der Lager dienen regelmäßig Schmiernippel, die im Staubdeckel angebracht sind. Die Schmiernippel haben, wie üblich, den Zweck, das Eindringen von Staub durch die Nachschmieröffnung zu verhindern.Dust cover with relubrication opening for support rollers The invention refers to dust cover with a lubrication hole as part of a labyrinth seal a support roller bearing, which is screwed onto the stationary roller axis Has lockable bearing cone as the inner race. The roles are common Supported by ball bearings on a continuous axle or on two axle journals. The bearings are connected by fixed or rotating dust covers with a sealing ring or a labyrinth seal against ingress of dust protected. Lubricating nipples in the dust cover are regularly used to relubricate the bearings are appropriate. As usual, the purpose of the grease nipples is penetration to prevent dust through the relubrication opening.

Die Verwendung von Schmiernippeln und der durch die Befestigung der Schmiernippel mit dem Staubdeckel entstehende Aufwand ist entbehrlich, wenn bei einer Tragrolle mit Labyrinthdichtung in dem das Lager abdeckenden Staubdeckel eine nach außen gerichtete Auswölbung, vorzugsweise in Form einer Halbkugel, ausgeprägt und in dieser eine Bohrung zum Nachschmieren angebracht wird. Durch die Anordnung des Schmierloches in der erwähnten, etwa halbkugelförmigen Auswölbung erhält das Schmierloch eine solche Lage, daß es weitgehend gegen Verschmutzung geschützt ist. Da die Auswölbung praktisch stets mit dem Schmiermittel gefüllt ist, so verhindert dies in Verbindung mit dem kleinen Durchmesser des Schmierlochesdas Eindringen des Staubes. Es werden so der Schmiernippel und seine Befestigungsmittel im Staubdeckel entbehrlich.The use of grease nipples and the attachment of the Grease nipple with the dust cover is unnecessary if at a roller with a labyrinth seal in the dust cover covering the bearing outward bulge, preferably in the shape of a hemisphere, pronounced and in this a hole is made for relubrication. By the arrangement of the lubrication hole in the hemispherical bulge mentioned Lubrication hole in such a position that it is largely protected against contamination. Since the bulge is practically always filled with the lubricant, this prevents it This in connection with the small diameter of the lubrication hole prevents the penetration of the Dust. This is how the grease nipple and its fasteners in the dust cover become dispensable.

Auf dem Lagerkonus undrehbar befestigte Staubschutzdeckel haben aber den Nachteil, daß die Schmieröffnung beim Einstellen des Lagerkonus in eine für das Nachschmieren ungünstige Stellung kommen kann.However, dust covers that are non-rotatably attached to the bearing cone have the disadvantage that the lubrication opening when adjusting the bearing cone in a for relubrication can come to an unfavorable position.

Erfindungsgemäß ist der Deckel so ausgebildet, daß er auf dem ruhenden Lagerkonus um dessen Achse in Umfangsrichtung verstellbar angebracht ist. Mit dieser Ausbildung des Deckels ist erreicht, daß die Schmieröffnune, am Staubschutzdeckel nach dem Einstellen des Lagerkonus wieder in eine Lage gebracht wird, in der ungehindert nachgeschmiert werden kann.According to the invention, the cover is designed so that it is resting on the Bearing cone is attached adjustable about its axis in the circumferential direction. With this Formation of the cover is achieved that the lubrication opening on the dust cover after setting the bearing cone is brought back into a position in which unhindered can be relubricated.

Zwei Ausführungsbeispiele der Erfindung sind im folgenden an Hand der Zeichnung beschrieben, die sich durch die Art der Befestigung des Staubdeckels unterscheiden. In der Zeichnung ist die Tragrolle mit 1 bezeichnet, in jedem Ende der Rolle sitzt fest ein aus Blech gepreßter Ring 2 mit U-förmigem Querschnitt, der umgebogene Rand 3 des äußereg,,$ch#g., kels 4 legt sich gegen die Stirnseite der Rolle 1, und der innere Schenkel 5 dient zur Befestigung des mit der Rolle 2 rotierenden Lagerkörpers 6. Dieser ist aus einem Blech gepreßt und nimmt die in einem Käfig 7 geführten Kugeln 8 auf, die zur Lagerung des Konus 9 dienen.Two embodiments of the invention are described below with reference to the drawing, which differ in the type of attachment of the dust cover. In the drawing, the support roller is denoted by 1 , a ring 2 pressed from sheet metal with a U-shaped cross-section sits firmly in each end of the roller, the bent edge 3 of the outer g ,, $ ch # g., Kels 4 lies against the end face the roller 1 and the inner leg 5 is used for fastening of the rotating roller 2 with the bearing body 6. This is pressed from a metal sheet and absorbs the guided in a cage 7 balls 8 serving for supporting the cone. 9

Auf dem zylindrischen Teil 10 des Konus 9 sitzt drehbar mit seinem inneren Flansch 11 der Staubdeckel 12 und ist durch einen Sprengring 13 gegen axiale Verschiebung gesichert. Der Staubdeckel greift mit seinem äußeren Flansch 14 in den nach außen offenen Ring 2 ein, der mit Fett gefüllt ist. Mit dem inneren Flansch 5 des Ringes ist ein U-förmig aus Blech gepreßter, nach innen offener Ring 15 verbunden, der zusammen mit dem Flansch 14 des Staubdeckels eine Labyrinthdichtung bildet, die das Eindringen von Staub durch den Spalt zwischen dem Flansch 14 und dem Schenkel 4 des Ringes 2 verhindert.On the cylindrical part 10 of the cone 9 , the dust cover 12 is rotatably seated with its inner flange 11 and is secured against axial displacement by a snap ring 13. The dust cover engages with its outer flange 14 in the ring 2 which is open to the outside and which is filled with grease. With the inner flange 5 of the ring, a U-shaped pressed sheet metal, inwardly open ring 15 is connected, which together with the flange 14 of the dust cover forms a labyrinth seal that prevents the penetration of dust through the gap between the flange 14 and the leg 4 of the ring 2 prevented.

Oberhalb der öffnung des Ringes 2 ist aus dem Staubdeckel 12 ein etwa halbkugelförmiger Teil 16 nach außen gewölbt, er hat eine Bohrung 17, die zum Nachschmieren dient. Diese öffnung ist durch ihre Lage gegen Eindringen von Staub und Schmutz geschützt, und etwa eindringender Staub sammelt sich im Ring 2, gelangt also nicht in das Lager selbst. Der Krümmungsradius des Teiles 16 ist vorzugsweise so bestimmt, daß die Wölbung des Teiles 16 sich den üblichen Schmierpressen anpaßt.Above the opening of the ring 2, an approximately hemispherical part 16 is curved outward from the dust cover 12; it has a bore 17 which is used for relubrication. This opening is protected by its location against the ingress of dust and dirt, and any dust that may penetrate collects in the ring 2, so does not get into the bearing itself. The radius of curvature of the part 16 is preferably determined so that the curvature of the part 16 is customary grease guns.

Die Ausführung nach der rechten Hälfte der Zeichnung unterscheidet sich von der der linken durch die andere Art der Befestigung des Staubdeckels 12. Der zylindrische Teil des Lagerkonus hat eine Nut 18, in Flansch 11 nach innen gedrückte Sicken 19 eingreifen. Diese Sicken legen den Staubdeckel ebenso wie der Sprengring in axialer Richtung fest.The embodiment according to the right half of the drawing differs from that of the left in that the dust cover 12 is fastened differently. The cylindrical part of the bearing cone has a groove 18, in the flange 11 inwardly pressed beads 19 engage. These beads fix the dust cover as well as the snap ring in the axial direction.
