Abstract[English]
The bicycle chain according to the invention is composed of a string of articulated links formed by pairs of outer links (1), stiffened by bolts (2) and pairs of inner links (3) that move freely on bolts (2) spaced apart from each other through rollers (4) having the pitch (distance between holes) Pe=P-2c and Pi=P-2a+2c or Pe=Pi+2s and Pi=P-2a-2s, with the embossed holes of the inner cylindrical links on the outside and on the inside with a portion of the same radius and a portion of length (M1) with an surface with the radius generator =r, having chamfered links at the ends on the surfaces (10, 11, 12, 13) with the angle α=arctangH/E, and the minimum clearance ( a) between the axis of symmetry of the bolt and the axis of symmetry of the embossed holes of the inner links is a≥N 1 *(sinα)/2.[French]
La chaîne de vélo selon l'invention est composée d'une chaîne de maillons articulés formés par des paires de maillons extérieurs (1), rigidifiés par des boulons (2) et des paires de maillons intérieurs (3) qui se déplacent librement sur des boulons (2) espacés les uns des autres par des galets (4) présentant un pas (distance entre trous) de Pe = P-2c et Pi = P-2a+2c ou Pe = Pi+2s et Pi = P-2a-2s, avec les trous gaufrés des maillons cylindriques intérieurs à l'extérieur et à l'intérieur, avec une portion de même rayon et une portion de longueur (M1), dont une surface avec le générateur de rayon = r, comprenant des maillons chanfreinés aux extrémités sur les surfaces (10, 11, 12, 13) avec l'angle α = arctangH/E, et le jeu minimum (a) entre l'axe de symétrie du boulon et l'axe de symétrie des trous gaufrés des maillons intérieurs est a > N 1 * (sinα)/2.
