Description

Es ist bekannt, daß es verschiedene Bauarten von Freilaufkupplungen gibt, unter anderem Klauenfreilaufkupplungen und Klemmkörperfreilaufkupplungen.It is known that there are various types of one-way clutches, including claw clutches and sprag clutches.

Diese Bauarten bestehen allerdings aus einer mehr oder weniger großen Anzahl mechanischer Bauteile und sind durch einen hohen Fertigungsaufwand gekennzeichnet.However, these types consist of a more or less large number of mechanical Components and are characterized by high manufacturing costs.

Der im Anspruch angegebenen Erfindung liegt das Problem zugrunde, aufwendige Bauformen von Freilaufkupplungen zu ersetzen.The invention specified in the claim is based on the problem of complex designs of Replace one-way clutches.

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, einen einfachen Aufbau, eine geringe Bauhöhe und einen geringen Fertigungsaufwand zu erzielen.The advantages achieved by the invention are, in particular, a simple structure, a to achieve low overall height and low manufacturing costs.

Durch den Einsatz verschiedener Werkstoffe, z. B. Papier, Metall oder Kunststoff und verschiedenen Oberflächenbeschaffenheiten von Welle und Band bzw. Folie dürften sich unterschiedliche Momente übertragen lassen.By using different materials, e.g. B. paper, metal or plastic and various Surface properties of the shaft and band or film are likely to differ Let moments be transferred.

Claims (1)

Wirkprinzip einer Freilaufkupplung zum Trennen bzw. Verbinden von Antriebswelle und Nabe je nach vorliegender Drehrichtung, gekennzeichnet durch folgende Merkmale:
  • 1. auf einer Welle sitzt
  • 2. eine vorgespannte Wicklung aus mehreren Lagen Band oder Folie, deren äußerste Lage mit der darunterliegenden Lage fest verbunden ist, wodurch die Wicklung gleichzeitig die Funktion der Nabe übernimmt
    • 2.1 die Vorspannung wird durch ein vormaliges Aufwickeln auf einen Dorn kleineren Durchmessers erreicht.
Operating principle of a one-way clutch for separating or connecting the drive shaft and hub depending on the direction of rotation, characterized by the following features:
  • 1. sits on a shaft
  • 2. a pre-tensioned winding of several layers of tape or film, the outermost layer of which is firmly connected to the layer below, whereby the winding simultaneously takes over the function of the hub
    • 2.1 the pretension is achieved by previously winding it onto a mandrel of smaller diameter.
