<p>Device for a toothed belt wheel (1) comprising a toothed rim at the perimeter of the wheel, where the rim is composed of a number of segments (10) that are retained in relation to each other in a circle. The segments (10) can either be retained between two side plates (3, 4) that extend along the whole of the periphery of the wheel (1) or are retained on a casing (35) that extends between, and is fastened to, two side plates (3,4). The segments (10) are manufactured from extruded profiles that are cut to the right length. To ensure the correct positioning of the segments (10) they are loosely attached to the wheel (1), a toothed belt is placed around the toothed edge and the segments (10) are displaced to give a firm engagement with the toothed belt. Thereafter the segments (10) are fastened.</p> |
