Abstract
Device including an inner shaft and an outer body rotatably mounted about an axis with respect to the shaft via at least one rolling bearing, the rolling bearing including an inner ring mounted on the inner shaft and an outer ring mounted in a housing of the outer body, the device including an automatic backlash elimination mechanism. The automatic backlash elimination mechanism includes a first washer having a tapered surface, and an elastic element in contact with the tapered surface of the first washer, the elastic element structured and arranged to generate a radial return force that is converted, by means of the tapered surface, into an axial force in order to eliminate the backlash related to the mounting of the rolling bearing. The first washer can be mounted on the shaft, in which case the elastic element generates a centripetal return force, or it can be mounted in the bore of the outer body, in which case the elastic element generates a centrifugal return force. A second washer can be provided so that the elastic element is positioned between the first washer and the second washer. The angle formed by the tapered surface and a plane perpendicular to the aforementioned axis is smaller than 12°. The invention also includes a wheel for a cycle, such as a bicycle, and a hub therefore which includes such device.
