Description

Wälzlagerkäfig aus Sintermetall Es sind Wälzlagerkäfige bekanntgeworden, die auf pulvermetallurgischem Weg hergestellt sind und die sich durch eine rationelle Fertigung ohne spanabhebende Bearbeitung auszeichnen. Die bekannten Wälzlagerkäfige dieser Art sind jedoch alle aus einem Stück hergestellt, obwohl es selbstverständlich bereits bekannt ist, Wälzlagerkäfige bzw. -laufbahnen aus einzelnen, miteinander verbindbaren Segmenten herzustellen. Da jedoch zum Verdichten des Metallpulvers ein Druck in der Größenordnung von 4 bis 8 t pro cm2 der projizierten Preßfläche erforderlich ist, werden bei Preßteilen mit großer Preßfläche Pressen mit sehr hohen Druckvermögen benötigt. Zudem nehmen solche Preßlinge, die ungeteilt ausgebildet sind und eine große Preßfläche haben, einen sehr großen Durchmesser ein, so daß die Kanalweiten der in der Sintertechnik verwendeten Durchstoßöfen nicht mehr ausreichen.Rolling bearing cage made of sintered metal Rolling bearing cages have become known which are produced by powder metallurgy and which are characterized by a rational Mark production without machining. The well-known roller bearing cages however, these types are all made in one piece, although it goes without saying is already known, rolling bearing cages or raceways from individual, with each other to produce connectable segments. However, as to compact the metal powder a pressure of the order of 4 to 8 tons per cm2 of the projected pressing surface is required, presses with very high presses are used for pressed parts with a large pressing surface Printing capacity required. In addition, take such compacts, which are formed undivided are and have a large pressing surface, a very large diameter, so that the channel widths of the pusher ovens used in sintering technology are no longer sufficient.

Diese Nachteile sind durch die Erfindung bei einem Wälzlagerkäfig aus Sintermetall dadurch behoben, daß er erfindungsgemäß aus einzelnen gepreßten und gesinterten Segmenten besteht, die mittels gestanzter und geprägter Seitenscheiben aus Blech verbunden sind. In vorteilhafter Ausgestaltung der Erfindung liegen die Trennstellen der Segmente in den Wälzkörpertaschen. Da bei den erfindungsgemäßen Wälzlagerkäfigen aus Sinterwerkstoffen auf der Basis von Eisen- und NE-Metallen die Käfige aus Segmenten zusammengesetzt sind, können diese in kleineren, einfacheren und infolgedessen billigeren Preßwerkzeugen gefertigt werden. Da auch die projizierte Preßfläche dieser Segmente kleiner ist, als bei den bekannten Käfigen, die aus einem Stück hergestellt sind, können Pressen mit weniger hohem Druckvermögen verwendet werden. Schließlich reichen auch die Kanalweiten der in der Sintertechnik verwendeten Durchstoßöfen für das Sintern dieser Segmente aus.These disadvantages are due to the invention in a roller bearing cage remedied from sintered metal by the fact that it is pressed according to the invention from individual and sintered segments, which are made by means of stamped and embossed side plates are connected from sheet metal. In an advantageous embodiment of the invention, the Separation points of the segments in the rolling element pockets. Since the invention Rolling bearing cages made of sintered materials based on ferrous and non-ferrous metals The cages are composed of segments, these can be broken down into smaller, simpler ones and consequently cheaper dies are made. Since the projected The pressing surface of these segments is smaller than in the case of the known cages, which consist of a Pieces are made, presses with less high pressure capacity can be used will. Finally, the channel widths used in the sintering technique are also sufficient Pusher furnaces for sintering these segments.

In der Zeichnung zeigt Fig. 1 einen vollständigen Wälzlagerkäfig, der in dem gewählten Ausführungsbeispiel für ein Zylinderrollenlager bestimmt ist; Fig. 2 zeigt ein Segment desselben, Fig. 3 die Form des Querschnitts im Schnitt A-A und Fig. 4 im Schnitt B-B; Fig. 5 und 6 lassen die Verbindungsmittel des Käfigs erkennen.In the drawing, Fig. 1 shows a complete rolling bearing cage, which is intended in the selected embodiment for a cylindrical roller bearing; Fig. 2 shows a segment of the same, Fig. 3 shows the shape of the cross section in section A-A and Fig. 4 in section B-B; Figs. 5 and 6 leave the connecting means of the cage recognize.

Der Rollenlagerkäfig nach Fig. 1 weist drei Segmente auf. Die Trennstellen 1 der Segmente liegen in den Käfigtaschen. Das einzelne Segment, wie es in Fig. 2 wiedergegeben ist, wird auf bekanntem pulvermetallurgischem Wege gepreßt und gesintert. Die Stirnflächen 2; 3 eines Segments werden zur Erzielung einer besseren Führung stumpfwinklig ausgebildet und weisen vorteilhaft einen Winkel von beispielsweise 120° auf. Die Form des Querschnittes eines Segments läßt sich aus Fig. 3 im Schnitt A-A und aus Fig. 4 im Schnitt B-B ersehen. Am Käfigboden werden beim Preßvorgang außen und innen in Umfangrichtung die Nuten 5 eingepreßt, welche bei der Kalibrierung des Käfigs von einem U-förmigen Blechring 8 eingenommen werden. An der dem Käfigboden gegenüberliegenden Seite ist in Umfangrichtung ein Ansatz 6 vorgesehen, an welchem der Käfigdeckel 10 anliegt. Nach dem Pressen und Sintern werden Nietlöcher 7 in die Käfigstege der Segmente gebohrt. Für den Zusammenbau werden die einzelnen Segmente in eine Matrize eingelegt, die genau die negative Form des Käfigs aufweist. Danach wird der U-förmige Blechring 8 in die Ausnehmungen 5 eingepreßt. Die Maße des U-förmigen Blechrings 8 und der Aussparungen 5 sind so gehalten, daß ein genügend großer Zusammenhalt der Einzelteile bis zur Fertigmontage gewährleistet. Mit diesem Arbeitsvorgang ist gleichzeitig ein Maßkalibrieren des Käfigs verbunden. Nach dem Einlegen der Rollkörper 9 wird der Käfigdeckel 10 aufgelegt. Danach werden der Blechring 8, der Käfigdeckel 10 und der Käfigkörper 12 durch Niete 11 verbunden.The roller bearing cage according to FIG. 1 has three segments. The separation points 1 of the segments are in the cage pockets. The single segment, as shown in Fig. 2 is shown, is pressed and sintered in a known powder-metallurgical way. The end faces 2; 3 of a segment are used to achieve better leadership formed obtuse angled and advantageously have an angle of, for example 120 °. The shape of the cross section of a segment can be seen from Fig. 3 in section A-A and from Fig. 4 in section B-B. At the bottom of the cage are during the pressing process outside and inside in the circumferential direction, the grooves 5 pressed in, which during the calibration of the cage can be taken up by a U-shaped sheet metal ring 8. At the bottom of the cage opposite side, a shoulder 6 is provided in the circumferential direction, on which the cage cover 10 is applied. After pressing and sintering, rivet holes 7 in the cage bars of the segments are drilled. The individual segments are used for assembly placed in a die that has exactly the negative shape of the cage. Thereafter the U-shaped sheet metal ring 8 is pressed into the recesses 5. The dimensions of the U-shaped Sheet metal ring 8 and the recesses 5 are held so that a sufficiently large cohesion of the individual parts guaranteed up to the final assembly. With this operation is at the same time a dimensional calibration of the cage connected. After inserting the rolling elements 9 the cage cover 10 is placed. Then the sheet metal ring 8, the cage cover 10 and the cage body 12 are connected by rivets 11.

Die so hergestellten Käfige besitzen neben dem Vorteil einer wirtschaftlichen Herstellungsweise eine große Stabilität und weisen infolge der Ausführung des Käfigkörpers aus Sintermetall hervorragende Notlaufeigenschaften auf. Zu deren Verbesserung kann der Käfigkörper auch noch mit einem geeigneten Schmiermittel getränkt werden.The cages produced in this way have the advantage of being economical Manufacturing method of great stability and have due to the design of the cage body made of sintered metal has excellent emergency running properties. Can improve it the cage body can also be impregnated with a suitable lubricant.

Wenn das erfindungsgemäße Verfahren auch an der Herstellung eines Käfigs für Zylinderrollenlager dargestellt worden ist, so ist es jedoch keineswegs auf diese Bauform beschränkt.If the inventive method is also involved in the production of a Cage for cylindrical roller bearings has been shown, but it is by no means limited to this design.
