Description
Die Erfindung bezieht sich allgemein auf Lagernäpfe für Nadellager und insbesondere erfindungsgemäß auf doppelwandige, gezogene Nadellagernäpfe, die einen aus einem äußeren Napf und einem inneren Napf gebildeten Mantel haben.The This invention relates generally to bearing cups for needle roller bearings and more particularly according to the invention on double-walled, drawn needle bearing cups, one from an outer bowl and an inner cup formed coat.

Aus dem vorstehenden ergeben sich Nachteile der bekannten Vorrichtungen und Verfahren. Es wäre daher vorteilhaft, eine Alternative zu schaffen, mit der die dargestellten Nachteile und Beschränkungen überwunden werden. Eine solche erfindungsgemäße Alternative wird im folgenden im einzelnen beschrieben.Out The above results in disadvantages of the known devices and procedures. It would be therefore advantageous to provide an alternative with which the illustrated Overcome disadvantages and limitations become. Such an alternative according to the invention will be described below described in detail.

Die doppelwandige Napfausbildung gestattet auch die Verwendung von zwei vollkommen unterschiedlichen Materialien zum Schaffen einer bimetallischen Struktur. Typische gezogene Nadellagernäpfe werden bei ihren Anwendungen durch ein Gehäusematerial mit einem Festsitz oder Preßsitz gehalten. Probleme können auftreten, wenn das Gehäusematerial einen höheren Wärmedehnungskoeffizienten hat als das Napfmaterial. Wenn in diesem Fall die Betriebstemperaturen ansteigen, kann das unterschiedliche Wachstum zwischen dem Napfmaterial und dem Gehäusematerial zur Folge haben, daß der Festsitz oder Preßsitz verlorengeht. Ferner hat allgemein das Gehäusematerial eine nicht ausreichende Stärke, um als Laufbahnoberfläche zu dienen. Ein typisches Beispiel würde ein Napfmaterial auf Eisenbasis sein, das in einem Aluminiumgehäuse verwendet wird.The Double-walled well formation also allows the use of two completely different materials to create a bimetallic Structure. Typical drawn needle roller cups are used in their applications through a housing material with a tight fit or press fit held. Problems can occur when the housing material a higher one Has thermal expansion coefficient as the cup material. If in this case the operating temperatures may increase, the different growth between the cup material and the housing material entail that the tight fit or press fit get lost. Further, in general, the case material is insufficient in strength as a raceway surface to serve. A typical example would be an iron-based cup material its in an aluminum case is used.
Somit hat eine bimetallische Struktur gemäß der Erfindung einen Vorteil, indem ein doppelwandiger Napf gebildet werden kann mit einem dünneren inneren Napf, der aus einem Material hergestellt ist, das zur Anwendung als Laufbahn geeignet ist, und mit einem äußeren Napf, der aus einem Material hergestellt ist, das sich bei erhöhten Temperaturen in enger Beziehung zu dem Gehäusematerial ausdehnt. Gemäß diesem Ausführungsbeispiel wird bei erhöhten Temperaturen der Festsitz oder Preßsitz zwischen dem äußeren Napf und dem Gehäuse aufrecht erhalten. Zusätzliche Vorteile können erreicht werden, wenn man ein rostfreies Stahlmaterial für den äußeren Napf verwendet, um den freiliegenden Bereich des Napfes gegen Korrosion zu schützen.Consequently a bimetallic structure according to the invention has an advantage in that a double-walled bowl can be formed with a thinner inner Cup made of a material to be used suitable as a track, and with an outer cup made of a material is made, which at elevated temperatures in close Relationship to the housing material expands. According to this embodiment is elevated at Temperatures of tight fit or press fit between the outer cup and the housing maintained. additional Benefits can can be achieved by using a stainless steel material for the outer cup Used to protect the exposed area of the bowl against corrosion to protect.
