Description

Kunststoffsleitrolle und Lagerbuchse Die Neuerung bezieht sich auf Gleitrollen und Lagerbuchsen aus Kunststoff, welche insbesondere an Türhaltevorrichtungen und Scharnieren für Kraftfahrzeuge Verwendung finden. Jedoch auch an Vorrichtungen anderer Art, bei denen anpreßdrücke auftreten, haben sich dieselben als vorteilhaft erwiesen. Die bekannten Kunststoffgleitrollen und Lagerbuchsen sind bisher mit glatten Oberflächen an den Mantelflächen und in der Bohrung versehen worden. Bedingt durch eine gewisse Elastizität des Kunststoffes und durch die einwirkenden Anpreßdrücke wird die Haftung der Oberflächen so groß, daß Quitschgeräusche entstehen.Plastic guide roller and bearing bush The innovation relates to sliding rollers and bearing bushes made of plastic, which are used in particular on door holding devices and hinges for motor vehicles. However, they have also proven to be advantageous on devices of other types in which contact pressures occur. The known plastic sliding rollers and bearing bushings are so far been provided with smooth surfaces on the lateral surfaces and in the bore. Due to a certain elasticity of the plastic and the applied pressure, the adhesion of the surfaces is so great that squeaking noises arise.

Durch die Kunststoffgleitrolle und Lagerbuchse gemäß der Neuerung werden diese Mängel behoben. Die Unterbrechung der Gleitflächen durch Längs-, Radial-, Spiral-, Kreuz- oder ähnlich verlaufende Riefen resorbiert die Adhäsion, welche durch die Anpreßkräfte entsteht und vermeidet dadurch die Quitschgeräusche.With the plastic sliding roller and bearing bush according to the innovation these shortcomings are corrected. The interruption of the sliding surfaces by longitudinal, radial, Spiral, cross or similar grooves resorbs the adhesion, which is created by the contact pressure and thus avoids the squeaking noises.

Ein weiterer Vorteil der Neuerung besteht darin, daß sich Schmierstoffe wie Molybdändisulfit, Graphit usw. in den Riefen sammeln können und dadurch bedingt eine gute Dauerschmierwirkung erreicht wird.Another advantage of the innovation is that lubricants such as molybdenum disulfite, graphite, etc. can collect in the grooves and thus conditionally a good permanent lubrication effect is achieved.

Durch die Unterbrechung der Gleitflächen gemäß der Neuerung wird die tragende Gleitfläche nicht zu sehr vermindert.By interrupting the sliding surfaces according to the innovation, the bearing sliding surface is not reduced too much.

In der Zeichnung ist eine beispielhafte Ausführung der Neuerung dargestellt.An exemplary embodiment of the innovation is shown in the drawing.

Es zeigen : Fig. I eine Kunststoffgleitrolle im Teilschnitt mit Radialriefen an der Mantelfläche und Kreuzriefen in der Bohrung. Fig. II die gleiche Kunststoffgleitrolle im Teilschnitt mit Längsriefen an der Mantelfläche und Kreuzriefen in der Bohrung.They show: FIG. 1 a plastic sliding roller in partial section with radial grooves on the outer surface and cross grooves in the bore. Fig. II the the same plastic sliding roller in partial section with longitudinal grooves on the outer surface and cross marks in the hole.

Fig. III eine zylindrische Lagerbuchse im Teilschnitt mit Radialriefen an der Mantelfläche und Längsriefen in der Bohrung.III shows a cylindrical bearing bush in partial section with radial grooves on the outer surface and longitudinal grooves in the bore.

Fig. IV eine Bundlagerbuchse im Teilschnitt mit Längsriefen an der Mantelfläche und Kreuzriefen in der Bohrung.Fig. IV a flange bearing bush in partial section with longitudinal grooves on the Outer surface and cross grooves in the hole.

Der Gegenstand der Neuerung sieht an der Kunststoffgleitrolle 1 und an der Lagerbuchse 4 ; 7 an den Mantelflächen 2 ; 5 ; 8 und in den Bohrungen 3 ; 6 ; 9 Längs-, Radial-, Kreuz-oder ähnlich verlaufende Riefen vor.The object of the innovation looks at the plastic roller 1 and on the bearing bush 4; 7 on the lateral surfaces 2; 5; 8 and in the bores 3; 6; 9 longitudinal, radial, cross or similar grooves.

Die Anordnung der Riefen wird dem jeweiligen Verwendungszweck angepaßt.The arrangement of the grooves is adapted to the respective purpose.

Der Gegenstand gemäß der Neuerung zeichnet sich aus durch wirtschaftliche Herstellung und verbesserte Funktion.The object according to the innovation is characterized by economic Manufacture and improved function.
