A device for the production of a locking or braking effect between two elements, such as a shaft (20) and a hub (21), which display two concentric, cylindrical surfaces, which device includes a sleeve, made in one piece, for axial insertion between the said surfaces. The sleeve is circumferentially divided into sleeve sections, which are separated by, at least partially, axially directed rows of holes in the body wall of the sleeve, and which are connected to each other by bridges, formed of the remaining wall material between the holes in the said rows. The body wall is provided with weak zones, designed to, through compression, project radially inwards and outwards into engagement with the said surfaces in order to achieve the said locking and braking effect. Circumferentially adjacent sleeve sections are designed to be displaced axially in relation to each other, in order to produce compressive forces upon the bridges, which thereby undergo such a change of position and/or form that the forces which produce the compression of the weak zones are then produced in the sleeve. |
