Wälzlagerroller bearing
Die vorliegende Neuerung bezieht sich auf Wälzlager, die ganz oder teilweise aus Kunststoff gefertigt sind,The present innovation relates to rolling bearings that are completely or are partly made of plastic,
Bs ist bekannt, die Teile eines Y/älzlagers, wie Laufringe, Wälzkörper und Käfig, aus Kunststoff zu fertigen. Trotz verschiedener Vorteile, wie geringes Gewicht, Widerstandsfähigkeit gegen chemische Stoffe und dgl*, weisen die bekannten Kunststoffe den Nachteil auf, daß im Laufe der Zeit eine Alterung stattfindet, die zu einer Versprödung des Werkstoffes führt. Dieses Verhalten, das eine Änderung der mechanischen Eigenschaften bewirkt, wird noch durch die Einwirkung des Lagerschmiermittels auf den Kunststoff verstärkt. Weiterhin haben Kunststoffe die Neigung, Wasser aufzunehmen, was zu einem Aufquellen der Teile und damit zu Mafiunbeständigkeit führt.It is known that the parts of a Y / roller bearing, such as races, rolling elements and cage, made of plastic. Despite various advantages, such as low weight, resistance to chemical substances and the like *, the known plastics have the disadvantage that in Aging takes place over time, which leads to embrittlement of the material. This behavior, which is a change in the mechanical Properties brought about is still through the action of the bearing lubricant reinforced on the plastic. Furthermore, plastics have a tendency to absorb water, which leads to swelling of the Parts and thus leads to Mafi inconsistency.
Zur Vermeidung dieser Nachteile' wird nach der vorliegenden Neuerung vorgeschlagen, die aus Kunststoff bestehenden Teile eines Wälzlagers allseitig mit einem dünnen metallischen Überzug zu versehen. Dieser Überzug, der z. B. aus Aluminium bestehen kann, wird dabei in bekannter Weise durch Hochvakuum-Bedampfung oder auf galvanischem Wege allseitig aufgebracht, so daß weder Luftsauerstoff noch Schmiermittel mit dem Kunststoff in Berührung kommen kann.To avoid these disadvantages, according to the present innovation proposed to provide the parts of a roller bearing made of plastic on all sides with a thin metallic coating. This Coating, the z. B. can consist of aluminum, is in a known manner by high vacuum vapor deposition or by galvanic means on all sides applied so that neither atmospheric oxygen nor lubricant with the Plastic can come into contact.
Bs ist zwar bekannt, Kunststoffteile, insbesondere Möbelbeschläge oder Zierteile für Automobile, mit Metallschichten zu überziehen. Diese Metallschichten haben jedoch einzig und allein die Aufgabe, das Aussehen, d. h» die dekorative Wirkung, der Kunststoffteile zu verbessern. Im Gegensatz hierzu - bei einem Wälzlager ist die dekorative Wirkung völlig nebensächlich - wird im vorliegenden Fall durch den allseitigen metallischen Überzug verhindert, daß der Luftsauerstoff oder die Luftfeuchtigkeit bzw, das Schmiermittel mit dem Kunststoff in Berührung kommt und damit Versprödung und Qtiellung des Werkstoffes, also eine Verschlechterung der Funktionsfähigkeit hervorruft.Bs is known, plastic parts, especially furniture fittings or Decorative parts for automobiles to be covered with layers of metal. The sole purpose of these metal layers, however, is to create the appearance, d. h »to improve the decorative effect of the plastic parts. In contrast to this - in the case of a roller bearing, the decorative effect is completely irrelevant - in the present case it is due to the all-round metallic coating prevents the atmospheric oxygen or humidity or, the lubricant comes into contact with the plastic and thus embrittlement and expansion of the material, i.e. a Causes deterioration in functionality.

In der beiliegenden Zeichnung ist als AusfüJarungsb ei spiel ein Kunststoffkäfig dargestellt, dessen Grundkörper 1 aus Kunststoff allseitig mit einem dünnen überzug 2 eines Metalles überzogen ist.In the accompanying drawing, a plastic cage is shown as an exemplary embodiment shown, the base body 1 made of plastic is covered on all sides with a thin coating 2 of a metal.
Es sei in diesem Zusammenhang betont, daß diese Maßnahme nicht nur bei Käfigen zweckmäßig ist, es besteht auch die Möglichkeit die übrigen Lagerteile, wie Singe und Wälzkörper, sowie die Befestigungshülsen od. dgl., soweit diese Teile aus Kunststoff gefertigt sind, in der gleichen Weise mit einem metallischen Werkstoff zu überziehen. Auch ist es selbstverständlich möglich, alle geeigneten Metalle bzw» Metallegierungen für den Überzug zu verwenden.It should be emphasized in this connection that this measure not only It is useful for cages, there is also the possibility of the other bearing parts, such as Singe and rolling elements, as well as the fastening sleeves od. The like. Insofar as these parts are made of plastic, to be coated in the same way with a metallic material. It is of course also possible to use all suitable metals or metal alloys for the coating.
