Titel der Neuerung Lagerung insbesondere für eine TretachseTitle of the innovation Bearing especially for a pedal axle

Anwendungsgebiet der NeuerungArea of application of the innovation

Die Neuerung betrifft eine Lagerung insbesondere für eine Tretachse eines Fahrrades, wobei die Tretachse mit Hilfe von zwei in Abstand angeordneten Wälzlagern drehbar gelagert ist und die beiden Wälzlager mit Hilfe einer Trägerhülse in einem Tretlagergehäuse aufgenommen sind.The innovation relates to a bearing, in particular for a pedal axle of a bicycle, wherein the pedal axle is rotatably mounted by means of two roller bearings arranged at a distance from one another and the two roller bearings are accommodated in a bottom bracket housing by means of a carrier sleeve.

Hintergrund der NeuerungBackground of the innovation

Eine solch gattungsgemäße Lagereinheit ist aus der DE 34 34 314 A1 vorbekannt. Die Befestigung dieses Lagers erfolgt derart, indem die vormontierte Einheit in das Tretlagergehäuse eingeführt wird und anschließend eine Feststellmutter aufgeschraubt und festgezogen wird. Durch das Verschrauben der Feststellmutter wird diese Innentretlagereinheit in das Tretlagergehäuse gezogen und per Preßsitz gehalten.Such a generic bearing unit is already known from DE 34 34 314 A1. This bearing is attached by inserting the pre-assembled unit into the bottom bracket housing and then screwing on a locking nut and tightening it. By screwing on the locking nut, this inner bottom bracket unit is pulled into the bottom bracket housing and held in place by a press fit.

Nachteilig dabei ist, daß eine relativ kompliziert geformte Feststell mutter in eine entsprechendes Gegengewinde im Tretlagergehäuse eingeschraubt werden muß. Diese Verfahrensweise macht eine solche Tretlageranordnung relativ teuer in Fertigung und Montage.The disadvantage here is that a relatively complicated locking nut has to be screwed into a corresponding counter thread in the bottom bracket housing. This procedure makes such a bottom bracket arrangement relatively expensive to manufacture and assemble.

Ausführliche Beschreibung der ZeichnungDetailed description of the drawing

Die in der einzigen Figur dargestellte Tretlagereinheit ist in einem mit 1 bezeichneten Tretlagergehäuse angeordnet. Die eigentliche Tretlagereinheit besteht aus einer hohlen Tretachse 2, die über zwei in einem Käfig geführte doppelreihige Kugellager 3 und 4 in einer Trägerhülse 5 gehalten ist. Zur axialen Anlage der Kugellager 3 und 4 ist die Tretachse 2 mit je zwei Schultern in Form eines Sicherungsringes 6 und 7 versehen. Die Trägerhülse 5 weist an ihren beiden Enden je eine Durchmessererweiterung 8 und 9 zur Aufnahme der beiden Kugellager 3 und 4 auf.The bottom bracket unit shown in the only figure is arranged in a bottom bracket housing marked 1. The actual bottom bracket unit consists of a hollow pedal axle 2, which is held in a carrier sleeve 5 via two double-row ball bearings 3 and 4 guided in a cage. For the axial positioning of the ball bearings 3 and 4, the pedal axle 2 is provided with two shoulders in the form of a locking ring 6 and 7. The carrier sleeve 5 has a diameter extension 8 and 9 at each of its two ends to accommodate the two ball bearings 3 and 4.

An die Stirnseite der beiden Außen laufringe 10 und 11 der Kugellager 3 und 4 schließt sich je ein Dichtungsträger 12 und 13 an, die in ihrer Innenmantelfläche je eine schleifende Dichtung 14 und 15 tragen.
20A seal carrier 12 and 13 is connected to the front side of the two outer races 10 and 11 of the ball bearings 3 and 4, each of which has a sliding seal 14 and 15 in its inner circumferential surface.
20

Neuerungsgemäß ist die Trägerhülse 5 mit einer umlaufenden Nut 16 versehen, in die eine durch das Tretlagergehäuse 1 geführte Befestigungsschraube 1 7 eingreift.According to the innovation, the carrier sleeve 5 is provided with a circumferential groove 16, into which a fastening screw 17 guided through the bottom bracket housing 1 engages.
