Abstract
Description
Gebiet der ErfindungField of the invention
Die Erfindung befasst sich mit der Lagerung von Wellen, die in Verdichtern von Klimaanlagen von Kraftfahrzeugen Verwendung finden. The invention relates to the storage of waves, which find use in compressors of air conditioning systems of motor vehicles.
Etwa aus
Damit die Riemenscheibe frei drehen kann, wenn sie nicht mit der Welle gekoppelt ist, ist die Riemenscheibe nahe ihrer Drehachse gelagert. Hier haben sich zur Lagerung einzel- oder auch doppelreihige Rillenkugellager durchgesetzt. Abgesehen davon, dass solche Kugellager relativ schwer sind, erfordern sie durch ihre Geometrie und Dimensionierung nicht nur in axialer, sondern auch in radialer Richtung relativ viel Bauraum. To allow the pulley to rotate freely when not coupled to the shaft, the pulley is mounted near its axis of rotation. Single or double row deep groove ball bearings have become established here for storage. Apart from the fact that such ball bearings are relatively heavy, they require by their geometry and dimensions not only in the axial, but also in the radial direction relatively much space.
Aufgabe der ErfindungObject of the invention
Daher liegt der Erfindung die Aufgabe zugrunde, die Nachteile im Stand der Technik zu überwinden und ein Lager bereitzustellen, welches in sehr einfacher und leichter Weise die Anforderungen für den Einsatz als Lager für die Riemenscheibe von Verdichtern von Kraftfahrzeugen erfüllt. It is therefore an object of the present invention to overcome the drawbacks of the prior art and to provide a bearing which satisfies the requirements for use as a bearing for the pulley of compressors of motor vehicles in a very simple and easy manner.
Zusammenfassung der ErfindungSummary of the invention
Diese Aufgabe wird mit den Merkmalen gemäß Anspruch 1 erfüllt. Vorteilhafte Aus- und Weiterbildungen eines Verfahrens zur Herstellung von Lagern gemäß Anspruch 1 sind den Ansprüchen 2 und 3 entnehmbar. This object is achieved with the features of
Wird der äußere Lagerring im Wesentlichen von einem Rohr gebildet, welches durch eine Einschnürung in zwei Schmiegungen im Sinne von Laufbahnen unterteilt ist, und wird der innere Lagerring ebenfalls von einem Rohr gebildet, dessen äußere, zur Symmetrieachse parallel verlaufende Kontur die Form eines in Richtung der Symmetrieachse gestreckten W hat, wird ein sehr leichtes, einfach und ohne großen Abfall herzustellendes Lager geschaffen, das den Anforderungen im Zusammenhang mit der Lagerung von Riemenscheiben von Verdichtern in Kraftfahrzeugen standhält.If the outer bearing ring essentially formed by a tube which is divided by a constriction in two Schmiegungen in the sense of careers, and the inner bearing ring is also formed by a tube whose outer, parallel to the axis of symmetry contour in the shape of a in the direction of Symmetry axis stretched W has created a very lightweight, easy to produce and without large waste warehouse that meets the requirements in connection with the storage of pulleys of compressors in motor vehicles.
Besonders einfach und kostengünstig ist die Herstellung von Lagern für Verdichter von Kraftfahrzeugen dann, wenn deren Lagerringe entsprechend Anspruch 2 durch plastische Verformung gebildet werden. Particularly simple and inexpensive is the production of bearings for compressors of motor vehicles when their bearing rings are formed according to
Werden die Lagerringe von Lagern für Riemenscheiben von Verdichtern gemäß Anspruch 3 durch Walzen hergestellt, sind nachfolgende Bearbeitungsschritte wie Schleifen, etc. nicht mehr oder nur noch in sehr eingeschränktem Umfang erforderlich. If the bearing rings of bearings for pulleys of compressors according to
