Abstract

In order, in the case of a pin cage for roller bearings, to reduce the sliding friction between the pins and the roller bore and to permit relubrication, the pins (14) are provided with an axial lubricating hole (15) which has at least one lubricating opening (16) opening into the roller bore (13). <IMAGE>

Description

Die Erfindung betrifft einen Bolzenkäfig nach dem Oberbegriff des Anspruchs 1.The invention relates to a pin cage according to the Preamble of claim 1.

Aus dem DE-Gm 69 20 779 ist ein derartiger Bolzen­ käfig bekannt. Nachteilig dabei ist, daß die zwi­ schen dem Bolzen und der Rollenbohrung auftretende Gleitreibung nur sehr schwer bzw. gar nicht durch Schmierstoff verringert werden kann. Ein Nachschmie­ ren ist wegen des kleinen Spaltes nicht möglich. Man hat deshalb die Bohrung der Rolle mit selbstschmie­ renden Überzügen (MOS₂ usw.) versehen, was aufwendig und teuer ist. Trotzdem kam es nach einiger Zeit zu Lagerschäden.Such a bolt is known from DE-Gm 69 20 779 known cage. The disadvantage here is that the two between the bolt and the roller bore Sliding friction very difficult or not at all Lubricant can be reduced. A re-smear Ren is not possible because of the small gap. Man therefore has the bore of the roller with self-smear Renden coatings (MOS₂, etc.) provided what is expensive and is expensive. Nevertheless, it happened after a while Bearing damage.

Es ist deshalb Aufgabe der Erfindung einen Bolzen­ käfig für Rollenlager so weiterzubilden, daß die Gleitreibung zwischen Bolzen und Rollenbohrung vermindert wird, eine zuverlässige einfache Schmie­ rung erfolgen kann und auch ein Nachschmieren er­ möglicht wird.It is therefore an object of the invention a bolt cage for roller bearings so that the Sliding friction between the pin and the roller bore is reduced, a reliable simple Schmie tion and relubrication is possible.

Die Lösung der Aufgabe ist aus dem kennzeichnenden Teil des Anspruchs 1 zu entnehmen. Die Anordnung nach Anspruch 2 bietet noch den Vorteil, daß beim Nachschmieren des Lagers gleichzeitig auch Bolzen und Rollenbohrung mit neuem Schmierstoff versehen werden.The solution to the problem is from the characteristic Part of claim 1. The order according to claim 2 also has the advantage that when Relubricate the bearing and bolts at the same time and roller bore with new lubricant will.

Die Erfindung soll an einem Ausführungsbeispiel näher erläutert werden. The invention is based on an embodiment are explained in more detail.  

Fig. 1 zeigt die Anordnung eines erfindungsgemäßen Lagers in einer Förderbandtrommel im Schnitt Fig. 1 shows the arrangement of a bearing according to the invention in a conveyor belt drum in section

Fig. 2 ein Zylinderrollenlager mit erfindungsge­ mäßem Bolzenkäfig im Schnitt Fig. 2 shows a cylindrical roller bearing with a pin cage according to the invention

In Fig. 1 ist die Bandtrommel mit 1 bezeichnet. Sie ist mit einem Rollenlager 2 gegenüber der Achse 3 drehbar gelagert und nach außen mit einer Gehäuse­ scheibe 4 und einer Labyrinthdichtung 5 abgedichtet. Nach innen ist neben dem Lager 2 noch eine Fett­ führungsscheibe 6 angeordnet. Die Achse 3 ist mit einer Nachschmierbohrung 7 versehen die in den Lagernachschmierraum 8 zwischen Lager 2 und Fett­ führungsscheibe 6 mündet. Die Nachschmierung erfolgt üblicherweise derart, daß mit einer Fettpresse solange Schmierstoff in die Nachschmierbohrung gedrückt wird, bis Altfett aus der Labyrinthdichtung austritt.In Fig. 1, the tape drum is designated 1 . It is rotatably supported with a roller bearing 2 with respect to the axis 3 and sealed to the outside with a housing disc 4 and a labyrinth seal 5 . In addition to the bearing 2 , a grease guide disk 6 is arranged. The axis 3 is provided with a relubrication hole 7 which flows into the bearing relubrication chamber 8 between the bearing 2 and the grease 6 . Relubrication is usually carried out in such a way that a grease gun is used to press lubricant into the relubrication hole until used grease emerges from the labyrinth seal.

Wie aus Fig. 2 ersichtlich ist, besitzt das Rollen­ lager 2 einen Außenring 9, einen Innenring 10, Rollen 11 und einen Bolzenkäfig 12. Die Rollen 11 sind axial durchbohrt und werden in ihrer Rollenboh­ rung 13 auf den Bolzen 14 gehalten. Die Bolzen 14 sind mit einer axial verlaufenden Schmierbohrung 15 versehen, die eine in der Rollenbohrung 13 mündende Schmieröffnung 16 aufweist. Somit läßt sich einfach und zuverlässig der enge Spalt zwischen Bolzen 14 und Rollenbohrung 13 mit Schmierstoff versorgen und die Reibung des Lagers vermindern. Wenn man nun das Lager noch so anordnet, daß die Schmierbohrung 15 des Bolzens 14 dem Lagernachschmierraum 8 zugewandt ist, so wird bei jedem Nachschmieren des Lagers auch Schmierfett über die Schmierbohrung 15 in den Spalt zwischen Bolzen 14 und Rollenbohrung 13 gelangen.As can be seen from FIG. 2, the roller bearing 2 has an outer ring 9 , an inner ring 10 , rollers 11 and a pin cage 12 . The rollers 11 are axially pierced and are held in their Rolle 13 drilling 13 on the bolt 14 . The bolts 14 are provided with an axially extending lubrication bore 15 , which has a lubrication opening 16 opening into the roller bore 13 . The narrow gap between the bolt 14 and the roller bore 13 can thus be supplied with lubricant in a simple and reliable manner and the friction of the bearing can be reduced. If you now arrange the bearing so that the lubrication hole 15 of the bolt 14 faces the bearing relubrication chamber 8 , then lubrication grease will also enter the gap between the bolt 14 and the roller bore 13 via the lubrication bore 15 each time the bearing is relubricated.
