Die vorliegende Erfindung betrifft eine verdrehsichere Befestigung von geschlossenen Ringen, Scheiben u. dgl. aus plastisch verformbarem Material in Ringnuten von Bohrungen und Wellen, insbesondere eine Befestigung von Anlaufborden und Dichtscheiben in Wälzlagern.The present invention relates to a torsion-proof fastening of closed rings, discs and the like. Made of plastically deformable material in annular grooves of bores and shafts, in particular an attachment of thrust rims and sealing washers in roller bearings.
Im Maschinenbau ist es oft erforderlich, irgendwelche Maschinenteile, beispielsweise Wälzlager, auf Wellen oder in Bohrungen zu befestigen, d. h. insbesondere in axialer Richtung zu fixieren. Die gleiche Aufgabe besteht vielfach auch in der Wälzlagertechnik, wo die Wälzkörper bzw..der Wälzlagerkäfig in axialer Richtung gesichert und geführt werden müssen. In beiden Fällen geschieht die axiale Fixierung im allgemeinen durch feste Borde oder Bunde. Wenn nun aus irgendwelchen Gründen feste Borde nicht zweckmäßig sind, weil das Einsetzen der Maschinenteile bzw. des Käfigs und der Wälzkörper unmöglich oder nur schwer durchzuführen ist, müssen die Borde lose ausgebildet und nachträglich, d. h. nach dem Einführen der Teile, eingesetzt werden.In mechanical engineering it is often necessary to have some To fasten machine parts, for example roller bearings, on shafts or in bores, d. H. in particular to be fixed in the axial direction. The same task often exists in rolling bearing technology, where the rolling elements or the rolling bearing cage must be secured and guided in the axial direction. In both cases, the axial fixation is generally done by means of fixed rims or collars. if now for some reason fixed shelves are not appropriate, because the insertion of the machine parts or the cage and the rolling elements is impossible or difficult to carry out, the rims must loosely formed and subsequently, d. H. after inserting the parts.
Es ist bekannt, an Stelle fester Bunde an Wellen u. dgl. geteilte Ringe, sogenannte Sprengringe oder Seegerringe zur axialen Fixierung zu verwenden. Es ist auch in der Wälzlagertechnik schon bekanntgeworden, solche Sprengringe zur axialen Führung der Käfige in entsprechende Ringnuten eines Lagerringes einzusetzen. Bei einer solchen Ausführung ist es auch bereits bekanntgeworden, die als federnde Ringe ausgebildeten Anlaufborde mit abgesetzten, in eine Nut der Hülse greifenden Paßteilen zu versehen, deren die Lage des jeweiligen Federringes gegenüber der Hülse in Achsrichtung festlegenden schrägen Sitzflächen mit entsprechenden Gegenflächen der Nut zusammenwirken und deren Drehsicherung durch am Umfang verteilt angeordnete Vorsprünge erfolgt, die in entsprechende Ausnehmungen der Hülse eingreifen. Weiterhin ist es bei Wälzlagern bekannt, geschlossene Ringe aus plastisch verformbarem Material durch radiales Aufweiten oder Stauchen in die Ringnuten in den Lagerringen einzusetzen. Eine andere bekannte Lösung besteht darin, vor dem Einsetzen kegelstumpfartig ausgebildete Ringe durch axiales Pressen flach zu drücken, wobei sie unter Verkleinerung des Innendurchmesser bzw. Vergrößerung des Außendurchmessers in die Nut eindringen und in dieser axial fixiert werden.It is known, instead of fixed collars on shafts and the like. Split rings, so-called snap rings or To use circlips for axial fixation. It has already become known in rolling bearing technology, such snap rings for the axial guidance of the cages in corresponding annular grooves of a bearing ring to use. In such a design, it has already become known that as a resilient Ring-shaped stop rims to be provided with offset fitting parts that engage in a groove in the sleeve, whose bevels defining the position of the respective spring ring relative to the sleeve in the axial direction Seat surfaces interact with corresponding mating surfaces of the groove and their rotation lock is carried out by projections distributed around the circumference, which are inserted into corresponding recesses of the Engage the sleeve. It is also known for rolling bearings to have closed rings made of plastically deformable materials Insert material into the ring grooves in the bearing rings by radial expansion or compression. Another known solution consists in forming a truncated cone prior to insertion Press the rings flat by axial pressing, reducing the inner diameter or enlargement of the outer diameter penetrate into the groove and axially in this be fixed.

nicht zulassen. So ist beispielsweise bei der Anwendung dieser Verfahren in der Wälzlagertech-Befestigung

nik eine einwandfreie Sicherung und Führung der Wälzkörper nicht gewährleistet.nik cannot guarantee that the rolling elements are properly secured and guided.
Bei Verwendung von Sprengringen besteht einmal der Nachteil, daß die Wälzkörper bzw. der Käfig durch die scharfen Kanten an der Trennstelle leicht beschädigt werden. Außerdem besteht bei dieser Ausführung die Gefahr, daß bei zu großer Federkraft die meist sehr dünnwandigen Lagerringe, insbesondere der Lageraußenring, verformt, d.h. unrund werden. Wird die Federkraft zu gering gewählt, so kann sich der Sprengring in der Nut des Lagerringes mitdrehen. Die ebenfalls bereits bekannte Ausführung, bei der die federnden Ringe, d. h. die Anlaufborde, und die entsprechenden Nuten mit Schrägflächen versehen sind, die die Ringe nach dem Auseinanderspreizen in axialer Richtung genau festlegen, weist neben der nicht auszuschließenden, wenn auch hier geringeren Verformung der Hülse durch die radiale Federkraft des Federringes zusätzlich noch einen weiteren Nachteil auf. So müssen in dem Außenring, d. h. in der Hülse, Ausnehmungen zur Aufnahme der die Drehsicherung der Ringe bewirkenden Vorsprünge vorgesehen werden. Bei der Herstellung dieser Ausnehmungen ist eine Verformung der dünnwandigen Hülsen unvermeidbar. Hinzu kommt noch, daß diese Ausnehmungen den Querschnitt der Hülse schwächen, also die Verformung wiederum begünstigen.When using snap rings there is the disadvantage that the rolling elements or the cage easily damaged by the sharp edges at the cutting point. In addition, there is in this version the risk that the mostly very thin-walled bearing rings, especially the bearing outer ring, deformed, i.e. becoming out of round. If the spring force is chosen too low, it can the snap ring also turn in the groove of the bearing ring. The already known version in which the resilient rings, d. H. the run-up rims and the corresponding grooves are provided with sloping surfaces are, which precisely define the rings after spreading apart in the axial direction, has next to the not to be ruled out, even if there is less deformation of the sleeve due to the radial spring force the spring washer also has another disadvantage. So must in the outer ring, i. H. in the Sleeve, recesses for receiving the anti-rotation projections of the rings are provided will. During the production of these recesses, the thin-walled sleeves are deformed unavoidable. In addition, these recesses weaken the cross-section of the sleeve, thus in turn favor the deformation.
Die Gefahr, daß die Lagerringe verformt, also unrund werden, besteht auch bei den bekannten geschlossenen Ringen, wenn die Nutfiefe zu gering ist. Wenn die Nuttiefe dagegen zu groß gewählt wird, erhalten die eingesetzten Scheiben oder Ringe keinen Halt, sie können sich leicht mitdrehen.The risk that the bearing rings will be deformed, i.e. out of round is also the case with the known closed rings when the groove depth is too small. If, on the other hand, the groove depth is chosen too large, the disks or rings used will not receive any Stop, they can turn easily.
Es ist nun, um diese Nachteile zu umgehen, bei Nadellagern, bei denen die zur axialen Sicherung des Nadelkäfigs bzw. der Nadeln vor dem EinsetzenIt is now, in order to avoid these disadvantages, in needle roller bearings in which the axial securing of the Needle cage or the needles before insertion
