Description

Die Erfindung betrifft- eine Verbesserung an Nadellagern nach dem Hauptpatent. Dieses bezieht sich auf ein Nadellager, bei dem die Nadelrollen in eirnemKäfig ,gehalten und geführt werden, der seinerseits in einem aus Blech oder Rohr bestehenden Laufring liegt und .durch umgewalzte Flansche des Laufringes seitlich gehalten und geführt wird. Nadelkäfig und Laufring bilden nach ihrer Vereinigung ein in sich -geschlossenes Lagersystem.The invention relates to an improvement in needle roller bearings according to the Main patent. This refers to a needle roller bearing in which the needle rollers are in a cage, held and guided, which in turn is made of sheet metal or Pipe existing race ring lies and .through rolled flanges of the race ring laterally is held and guided. The needle cage and the raceway are formed after they have been combined a self-contained storage system.

Es hat sich gezeigt, @daß die gleitende Reibung zwischen den äußeren, Stirnflächen des Nadelkäfigs und den umgewalzten Flanschen des Laufringes einen hohen Verschleiß der aufeinander gleitenden Flächen verursacht. Zur Behebung dieses Mangels wird erfindungsgemäß vorgeschlagen, zwischen den äußeren Stirnflächen des Nadelkäfigs und den nach innen umgebogenen Flanschen des Außenlaufringes, Führungsringe aus einem nicht metallischen Kunststoff einzufügen.It has been shown that the sliding friction between the outer, The end faces of the needle cage and the rolled flanges of the raceway one causes high wear of the surfaces sliding on each other. To fix this Deficiency is proposed according to the invention, between the outer end faces of the Needle cage and the inwardly bent flanges of the outer race, guide rings to be inserted from a non-metallic plastic.

Von der Patentinhaberin durchgeführte Versuche haben ergeben, daß die Gleiteigenschaften von Me= tall auf Kunststoff wesentlich günstiger sind als,die von Metall auf Metall. Ein Verschleiß ist praktisch nicht feststellbar, und die Laufgeräusche werden stark herabgemindert.Tests carried out by the patent proprietor have shown that the sliding properties of metal on plastic are much more favorable than that from metal to metal. Wear is practically not detectable, and the Running noises are greatly reduced.

Die Zeichnung veranschaulicht ein Ausführungsbeispiel der Erfindung. Es ist Abb. i ein Längsschnitt durch das Lager und Abb. 2 ein Teilschnitt durch den Laufring und,die Führungsringe vor ,dem Zusammenbau.The drawing illustrates an embodiment of the invention. Fig. 1 is a longitudinal section through the bearing and Fig. 2 is a partial section the race and, before assembly, the guide rings.

Der zylindrische Außenlaufring i wird vorzugsweise aus Stahlblech gezogen und im Bereich der Nadellaufflächen einsatzgehärtet. Die nach dem Zusammenbau umzüwalzenden Endteile 2 des Laufringen i werden durch bekannte Maßnahmen aus dem Härtungsprozeß ausgenommen. Die Nadelrollen 3 sind in einem Käfig 4 gruppenweise und achsparallel geführt. Nach dem Einschieben des Nadelkäfigs werden die beiden seitlichen Führungsringe 5, die aus einem nicht metallischen Kunststoff bestehen, eingesetzt und durch Umwalzen der Endteile 2,des Laufringes i befestigt.The cylindrical outer race i is preferably made of sheet steel drawn and case-hardened in the area of the needle running surfaces. The one after assembly Umzuwalzenden end parts 2 of the races i are known by known measures from the Hardening process excluded. The needle rollers 3 are in a cage 4 in groups and guided axially parallel. After sliding in the needle cage, the two lateral guide rings 5, which consist of a non-metallic plastic, inserted and fixed by rolling the end parts 2, the race i.
