Description
Blechkäfig für Radial-NadellagerSheet metal cage for radial needle roller bearings
Die Neuerung betrifft einen Blechkäfig für Radial-Nadellager zur Aufnahme von mindestens zwei Nadelreihen in eingestanzten Fenstern, deren Begrenzungsstege innere und äußere Haltekanten für die Nadeln bilden und der aus einem endlichen flachen Blechstreifen durch Aufrollen desselben hergestellt ist. Solche aus Flachfnaterial durch Stanzen und Biegen hergestellten Nadelkäfige weisen infolge ihrer geringen Materialstärke keine genügende Formsteifigkeit auf und das Zusammenschweißen der beiden Enden des aufgerollten Blechstreifens erfordert kostspielige Einrichtungen, die sich nur bei sehr großen Stückzahlen lohnen.The innovation relates to a sheet metal cage for radial needle roller bearings to accommodate at least two Rows of needles in punched-in windows with inner and outer retaining edges form for the needles and the same from a finite flat sheet metal strip by rolling it up is made. Those made of flat material through Needle cages produced by punching and bending have due to their low material thickness insufficient dimensional rigidity and that Welding the two ends of the rolled up sheet metal strip together requires expensive equipment, which are only worthwhile for very large quantities.
Der Neuerung liegt die Aufgabe zugrunde, das Zusammenfügen der Käfigenden unter gleichzeitiger Erhöhung der Formsteifigkeit des fertigen Käfigs in einfacher, ohne Spezialeinrichtungen ausführbarer Weise zu bewerkstelligen, indem neuerungsgemäß zwischen den Fenstern benachbarter Nadelreihen die Trennstelle des Käfigs überbrückende Bunde angeordnet und mit dem Käfigkörper fest verbunden s ind.The innovation is based on the task of joining the ends of the cage at the same time Increasing the dimensional stiffness of the finished cage in a simple way that can be carried out without special equipment Way to accomplish by renewing according to between the windows of adjacent rows of needles the separation point of the cage bridging collars arranged and firmly connected to the cage body are.
Die Zeichnung veranschaulicht ein Ausführungsbeispiel des Neuerungsgegenstandes. Der dargestellte Käfig weist zwei symmetrisch zueinander angeordnete Reihen von Fenstern 1 auf. Diese Fenster werden in Umfangsrichtung von den Kanten der Stege 2 begrenzt, die in mehrere Abschnitte unterteilt sind, und zwar in zwei seitliche, außerhalb des Nadelteilkreises axial verlaufende Stegabschnitte, einem innerhalb des Nadelteilkreises axial verlaufenden mittleren Stegabschnitt und zwei schräg zur Käfigachse verlaufenden, die äußeren mit dem inneren Stegabschnitt verbindende Abschnitte. Die Kanten der äußeren und inneren Stegabschnitte zxtfeier benachbarter Stege haben voneinander einen Abstand, der etwas kleiner ist als der DurchmesserThe drawing illustrates an exemplary embodiment of the subject of the innovation. The cage shown has two rows of windows 1 arranged symmetrically to one another. These windows are delimited in the circumferential direction by the edges of the webs 2, which are divided into several sections, namely into two lateral web sections running axially outside the needle pitch circle, a central web section running axially within the needle pitch circle, and two outer ones running obliquely to the cage axis with the inner web portion connecting sections. The edges of the outer and inner web sections zxtfeier adjacent webs are spaced apart from one another which is somewhat smaller than the diameter

der Nadel 3, so daß sie die Nadel nach außen und nach innen gegen Herausfallen sichern. Die Nadel kann trotzdem leicht in das Fenster eingeführt werden, und zwar von innen, wobei die mittleren Stegabschnitte zweier benachbarter Stege etwas auseinandergedrückt werden und sich nach dem Einbringen der Nadel wieder einander nähern. Die axiale Begrenzung der Nadeln 3 erfolgt einerseits durch die Käfigseitenränder 4 und andererseits durch den zwischen den beiden Nadelreihen verbleibenden, ringförmigen Abschnitt des Käfigkörpers.the needle 3, so that they secure the needle to the outside and inside against falling out. The needle can still be easily inserted into the window, from the inside, with the middle Web sections of two adjacent webs are pushed apart a little and after the Bringing the needles closer to each other again. The needles 3 are axially limited on the one hand by the cage side edges 4 and on the other hand by the annular section remaining between the two rows of needles of the cage body.
Mit 6 ist in der Zeichnung die Trennstelle bezeichnet, die beim Aufrollen des endlichen Blechstreifens, aus dem der Käfig hergestellt wird, entsteht. Diese Trennstelle 6 wird durch einen ringförmigen Bund 7 überbrückt, der im Bereich des Abschnittes des Käfigkörpers bohrungsseitig eingesetzt und durch mehrere über seinen Umfang verteilt angeordnete Schweißpunkte mit dem Käfig vereinigt ist. Der Bund kann ebenfalls aus einem flachen Blechstreifen durch Aufrollen erzeugt werden, es muß dann lediglich beim Zusammenfügen darauf geachtet werden, daß die Trennstelle 6 des Käfigkörpers und die Trennstelle des Bundes 7 nicht zusammenfallen. Bei entgegengesetzter Profilierung der Stegabschnitte wird man den Bund 7 mantelseitig am Käfigkörper anbringen und befestigen. Seine Materialstärke darf nicht das Maß der Durchkröpfung der mittleren Stegabschnitte übersteigen.With 6 the separation point is designated in the drawing, which arises when rolling up the finite sheet metal strip from which the cage is made. This separation point 6 is bridged by an annular collar 7, which is inserted on the bore side in the region of the section of the cage body and is united with the cage by several weld points distributed over its circumference. The federal government can also be produced from a flat sheet metal strip by rolling it up, it must then only be ensured when joining that the separation point 6 of the cage body and the separation point of the collar 7 do not coincide. If the web sections are profiled in the opposite direction, the collar 7 will be attached to the shell side of the cage body and fastened. Its material thickness must not exceed the extent of the cranking of the central web sections.
Das Ausführungsbeispiel veranschaulicht einen Käfig mit zwei Nadelreihen, es ist aber einleuchtend, daß bei Käfigen mit mehr als zwei Nadelreihen mehrere Bunde 7, jeweils zvrischen zwei Nadelreihen angeordnet, anzubringen sind0 Darüberhinaus besteht auch noch die Möglichkeit, im Bereich der Käfigseitenränder k dem Bund 7 entsprechende Ringe anzubringen.The embodiment illustrates a cage with two rows of needles, but it is evident that in cages with more than two rows of needles several coils 7, respectively zvrischen arranged two rows of needles are to attach 0 In addition, there is the possibility, in the region of the cage side edges k of the collar 7 to attach appropriate rings.
