Description

Die Erfindung betrifft einen Segmentkäfig für ein Kreuzrolleolager nach dem Oberbegriff des Anspruchs.The invention relates to a segment cage for a cross roller bearing according to the preamble of the claim.

Aus der DE-Patenlanmeldung D16S30, veröffentlicht am 28.04.55 ist ein derartiges Kreuzrollenlager bekannt Dabei besteht der Käfig aus einer Reihe von Segmenten, die jeweils zwei Rollen zu einer Gruppe zusammenfassen, wobei die Taschen für die Wälzkörper gegeneinander um 90° versetzt r.ind.From DE patent application D16S30, published Such a crossed roller bearing is known on 04/28/55. The cage consists of a number of Segments that combine two roles to form a group, with pockets for the rolling elements offset from each other by 90 ° r.ind.

Abgesehen von der aufwendigen Form eines solchen Käfigs muß bei der Montage des Käfigs und der Bestückung mit den Wälzkörpern immer darauf -Jo geachtet werden, daß die richtige Reihenfolge eingehalten wird und ;'ie Segmente in der richtigen Lage in das Lager eingebaut werden. Montagefehler sind dabei nicht auszuschließen.Apart from the complex shape of such a cage, when assembling the cage and the Always equip with the rolling elements -Jo care must be taken to ensure that the correct sequence is observed and that the segments are in the correct position in the Bearings are installed. Assembly errors cannot be ruled out.

Es ist deshalb Aufgabe i^r Erfindung, einen Segmentkäfig für ein Kreuzrollenlager der eingangs genannten Art dahingehend zu verbessern, daß ein einfacher und billig herzustellender Käfig verwendet werden kann, der lageunabhängig in das Lager eingebaut werden kann.It is therefore an object of the invention to provide a To improve segment cage for a crossed roller bearing of the type mentioned in that a simple and inexpensive to manufacture cage can be used, which is independent of the position in the warehouse can be built in.

Die Lösung dieser Aufgabe ist aus dem kennzeichnenden Teil des Anspruchs zu entnehmen.The solution to this problem can be found in the characterizing part of the claim.

Die Käfigsegmente nach der Erfindung zeichnen sich durch eine einfache Form aus und sind z, B. billig aus Kunststoff herstellbar, verschleißarm und weisen gute Dämpfungseigenschaften auf.The cage segments according to the invention are characterized by a simple shape and are, for example, cheap Plastic can be produced, has little wear and tear and has good damping properties.

Die Rollenführung an den Rollenabrundiingen ermöglicht wegen der min. Berührungsstellen hohe Gleitflächengeschwindigkeiten und schließt weitgehendst Laufflächenbeschädigungen an den Rollen durch Materialeinschlüsse in den Käfigtaschen aus. Weiterhin wird auch kein Schmierstoff an der Rollenlauffläche abgestreift Die Führung über die sonst unbenutzten Rollenabrundungen bewirkt niedrige Reibungs- und Verschleißeigenschaften.The roller guide on the roller roundings enables high sliding surface speeds due to the minimum contact points and closes as much as possible Damage to the running surface of the rollers due to material inclusions in the cage pockets. Farther no lubricant is wiped off the roller running surface either. The guide over the otherwise unused Rounding of the rollers results in low friction and wear properties.

Die Erfindung soll an einem Ausführungsbeispiel näher erläutert werden. Es zeigtThe invention is to be explained in more detail using an exemplary embodiment. It shows

In Fig. 1 und 2 sind der Außenring mit 1, der Innenring mit 2 und Wälzkörper mit 3 und die Käfigsegmente m;t 4 bezeichnetIn Fig. 1 and 2, the outer ring with 1, the Inner ring with 2 and rolling elements with 3 and the cage segments m; t 4

Wie aus F i g. 3 und 4 ersichtlich ist ist ein Segment 4 als flaches und ebenes Teil ausgebildet und weist vorzugsweise zwei gleiche als Langloch ausgebildete Taschen 4' zur Aufnahme der Wälzkörper 3 auf. Die Längsachse der Tasche 4' verläuft dabei quer zur Umlaufrichtung des Segments 4. Auf diese Weise ist sichergestellt, daß die Segmente 4 stets in der richtigen Lage zwischen Außenring 1 und Innenring 2 eingebaut werden.As shown in FIG. 3 and 4 can be seen, a segment 4 is designed as a flat and planar part and has preferably two identical pockets 4 ′ designed as elongated holes for receiving the rolling elements 3. the The longitudinal axis of the pocket 4 'runs transversely to the direction of rotation of the segment 4. In this way ensures that the segments 4 are always installed in the correct position between the outer ring 1 and the inner ring 2 will.
