Kammkäfig für Nadellager Comb cage for needle bearings

Me Erfindung betrifft einsn Kammkäfig für Nadellager aus Kunststoff. The invention relates to a comb cage for needle roller bearings made of plastic.

Derartige Käfige halten die Mädeln in axialer Richtung nicht zufriedenstellend. Es kommt häufig vor, daß die Nadeln trotz der Haftwirkung des Lagerfettes während der Lagerung oder bei der Montage aus dem Käfig rutschen und verlorengehen. Zwar kann man diesen Nachteil durch Verwendung von geschlossenen Kunststoffkäfigen vermeiden. Diese sind aber wegen der hohen Kosten des komplizierten Spritzwerkzeugs verhältnismäßig teuer. Um die Nadeltaschen herzustellen, müssen nämlich hier die als Kerne dienenden sogenannten Schieber für jede einzelne Tasche radial aus dem fertiggespritzten Käfig gezogen werden, während bei Kammkäfigen die Entfernung des ganzen Schiebersatzes in einer, nämlich der axialen Richtung erfolgen kann.Such cages do not hold the girls in the axial direction satisfactorily. It often happens that the needles despite the adhesive effect of the bearing grease during storage or during the Assembly slip out of the cage and get lost. It is true that this disadvantage can be overcome by using closed plastic cages avoid. However, these are relatively expensive because of the high costs of the complicated injection molding tool. To the needle pockets to produce, namely the so-called slides serving as cores for each individual pocket have to be radially removed from the finished injection molding Cage are pulled, while with comb cages the removal of the entire slide set in one, namely the axial Direction can be done.

Um nun auch bei Kammkäfigen sine gute axiale Sicherung der Nadeln unter billiger Herateilungsweise zu erreichen, schlägt die Erfindung vor? das freie Ende dar Nadelstege mit sich gegenüberliegenden die Nadeln hintergreifenden. Noeksn au versehen. Di©8© Hocken verhindern das Herausfallen dar Nad©ln und gestatten zugleich infolge ihrer Elastizität, daß der SoMefaersatz nach dom Spritsvorgang nach wie vor nur in einer Riohtimg gezogen wird. Dadurch sind die Torteile eines herkömmlichen Kammkäfigs und eines Nadelkäfigs mit Taschen in einem Produkt vereinigt.In order to achieve good axial securing of the needles in comb cages with inexpensive handling, does the invention propose ? the free end is the needle bars with opposite the needles engaging behind. Noeksn au provided. The squatting prevents the needles from falling out and at the same time, due to their elasticity, allows the synthetic fiber substitute to be pulled out only once after the spraying process. As a result, the gate parts of a conventional comb cage and a needle cage with pockets are combined in one product.

Um daa axiale Ziehen des Schiobersatzes weiter zu erleichtern, sind zweckmäßig zwischen den Nocken Ausnehmungen vorgesehen, die die Enden der Nadelstege senkrecht zum Käfigumfang durchsetzen. Somit trägt auch die Formgebung zur Elastizität der Stegenden bei.In order to further facilitate the axial pulling of the sliding block, recesses are expediently provided between the cams, which pass through the ends of the needle bars perpendicular to the circumference of the cage. The shape thus also contributes to the elasticity of the web ends.

Im folgenden wird die Erfindung anhand eines in der Zeichnung schematisch dargestellten Ausführungsbeispiels beschrieben!In the following the invention is described with reference to an embodiment example shown schematically in the drawing!

Sie mit 1 bezeichneten Nadelstege des Kammkäfigs 2 aus geepritztem Kunststoff bilden in bekannter Weise mit ihren sich gegenüberliegenden Seiten zylinderförmige Nester, die die Nadeln 3 in. radialer Richtung halten. An der offenen Seite des Kammkäfigs 2 weist jeder der !Tadelstage 1 ein Paar Nocken 4 auf, die die Nadeln 3 stirnseitig teilweise umgreifen und somit als axiale Begrenzung für die Nadeln 3 dienen. Damit die Nocken 4 den Spannungen beim Einsetzen der Nadeln 3 oder Herausziehen der Schieber nach dem Spritz-Vorgang leichter nachgeben, sind noch Ausnehmungen 5 zwischen den Nocken 4 vorhanden.You with 1 designated needle bars of the comb cage 2 from sprayed In a known manner, plastic form cylindrical nests with their opposite sides, which the needles 3 in. Radially Keep direction. On the open side of the comb cage 2, each of the blame stages 1 has a pair of cams 4, which the needles 3 face partially encompass and thus serve as an axial limit for the needles 3. So that the cams 4 withstand the stresses on insertion the needles 3 or pulling out the slide after the injection process give way more easily, there are still recesses 5 between the cams 4.
