Description
Die Erfindung betrifft eine Lagerbuchse mit einem zylindrischen Buchsenkörper und mindestens einem am axialen Ende des Büchsenkörpers angeordneten, nach außen gerichteten Kragen. The invention relates to a bearing bush with a cylindrical bushing body and at least one arranged at the axial end of the sleeve body, outwardly directed collar.
Buchsen der eingangs genannten Art sind in vielfältiger Ausgestaltung aus dem Stand der Technik bekannt und werden insbesondere an Lagerstellen eingesetzt, an denen ein nur geringes Lagerspiel zulässig ist. Durch eine radiale Kalibrierung kann dabei ein radiales Spiel aufgrund von Bautoleranzen der im Bereich der Lagerstelle eingesetzten Bauteile gewöhnlich minimiert werden. Bushings of the type mentioned are known in various embodiments from the prior art and are used in particular at bearings where only a small clearance is allowed. By means of a radial calibration, radial play can usually be minimized on account of structural tolerances of the components used in the region of the bearing.
Aufgrund mehrerer solcher Einzelbauteiltoleranzen, die sich unvorteilhaft in der Lagerstelle fokussieren, kommt es allerdings nicht nur zu einem radialen sondern auch zu einem unerwünschten axialen Spiel. Ein solches axiales Spiel führt nicht nur zu einer störenden Geräuschentwicklung während des Betriebs sowie einer unpräzisen Führung eines gelagerten Bauteils, sondern auch zu einem erhöhten Verschleiß und damit verbunden zu einer geringen Lebensdauer der Bauteile der Lagerstelle. Due to several such individual component tolerances that focus unfavorably in the bearing, it is not only a radial but also an undesirable axial play. Such axial play not only leads to a disturbing noise during operation and an imprecise guidance of a stored component, but also to increased wear and, associated therewith, to a short life of the components of the bearing.
Ein axiales Spiel kann zwar grundsätzlich durch Verringerung der Fertigungstoleranzen sämtlicher Bauteile minimiert werden, jedoch führt dies zu einer starken Kostensteigerung bei der Produktion der Bauteile. Although an axial clearance can be minimized basically by reducing the manufacturing tolerances of all components, but this leads to a sharp increase in costs in the production of components.
In der
In der
Der Erfindung liegt die Aufgabe zugrunde, eine Lagerbuchse gemäß dem Oberbegriff des Patentanspruchs 1 bereit zu stellen, die ein axiales Spiel in einfacher Weise reduziert bzw. ausgleicht, um konstruktions- und materialabhängig die Restkraft und somit die Reibung (Reibmoment) in der Lagerstelle einstellen zu können. The invention has for its object to provide a bearing bush according to the preamble of claim 1, which reduces an axial clearance in a simple manner or compensates for construction and material dependent on the residual force and thus the friction (friction) to adjust in the bearing can.
Zur Lösung dieser Aufgabe ist die erfindungsgemäße Lagerbuchse dadurch gekennzeichnet, dass in den Kragen im Bereich seines Außenrandes mehrere in Umfangsrichtung im Abstand voneinander liegende, in Axialrichtung nach außen vorspringende Nocken eingeprägt sind, derart, dass das Spiel in der Lagerstelle durch elastische und vorteilhafter Weise plastische Verformung auf nahezu Null reduziert wird. To solve this problem, the bushing according to the invention is characterized in that in the collar in the region of its outer edge a plurality of circumferentially spaced, axially outwardly projecting cams are embossed, such that the play in the bearing by elastic and advantageous plastic Deformation is reduced to almost zero.
Es hängt von der Geometrie der Nocken ab, ob das Lagerbuchsenmaterial beim Zusammendrücken vollständig gestaucht oder in Teilbereichen gebogen wird. It depends on the geometry of the cams, whether the bearing bush material is completely compressed or bent in some areas when compressed.
Eine geschlossene Prägung in Form der gemäß
Die Anordnung von mehreren Nocken an dem Außenrand der Anlagefläche ermöglicht es in vorteilhafter Weise, ein axiales Spiel der die Buchse aufweisenden Lagerstelle auszugleichen, indem die Nocken derart angeordnet und geformt sind, dass bei der Montage der Lagerbuchse die Nocken zumindest teilweise zusammengedrückt werden. Dadurch kommt es zu einer teilweise plastischen und teilweise elastischen Vorspannung, die ein sowohl bereits bei der Montage als auch im späteren Betrieb möglicherweise auftretendes Spiel kompensiert. The arrangement of a plurality of cams on the outer edge of the abutment surface advantageously makes it possible to compensate for axial play of the bearing having the bushing by arranging and shaping the cams in such a way that the cams are at least partially compressed during assembly of the bearing bush. This results in a partially plastic and partially elastic bias, which compensates for a game that may already occur during assembly as well as in later operation.
Die Nocken sind vorzugsweise zum Außenrand der flanschartigen Anlagefläche hin offen. The cams are preferably open to the outer edge of the flange-like contact surface.
Es sind vorzugsweise mindestens drei, vorzugsweise mindestens acht in gleichmäßigen Winkelabschnitten voneinander angeordnete Nocken vorgesehen, wobei die Anzahl der Nocken im wesentlichen abhängig ist von dem Durchmesser der Auflagefläche. There are preferably provided at least three, preferably at least eight equiangularly spaced cam arranged, wherein the number of cams is substantially dependent on the diameter of the support surface.
Die Nocken sind vorzugsweise aus dem Material der Anlagefläche derart herausgedrückt, dass sie an der Außenseite der Anlagefläche die Form von Ausbuchtungen und an der anderen Seite die Form von Einbuchtungen haben. The cams are preferably pressed out of the material of the contact surface in such a way that they have the shape of protrusions on the outside of the contact surface and the shape of indentations on the other side.
Ein Ausführungsbeispiel der Erfindung wird nachstehend mit Bezug auf die Zeichnung näher erläutert, die in einer perspektivischen Darstellung die erfindungsgemäße Lagerbuchse zeigt. An embodiment of the invention will be explained in more detail below with reference to the drawing, which shows the bearing bush according to the invention in a perspective view.
