    摘要： This invention relates to a device for correcting the alignment of the machining of a chainset housing (1b), the housing comprising a pair of half-casings (2a, 2b) inserted in one of the openings of the housing (1b) to position the parts (3a, 3b) of a pedalling effort or chain tension sensor which pivots inside the casing (2) and positions the shaft of the chainset (4) so as to rotate eccentrically compared to the pivot axis (Y-Y′) of the sensor (3) inside the casing (2), said device being characterized in that the sensor enables pivoting of the half-casings via a rolling-contact bearing (5) which, in a cross section passing through the axes of the half-casings, allows a ball-joint-like turning of the pivot axis of the effort sensor (3) with respect to the axes of the half-casings in order to allow the pivot axis of the sensor to be positioned independently of the axes of the two half-casings so that errors of alignment between the axes of the two half-casings can be eliminated.

    摘要： A roller chain including a series of inner links each formed by a plurality of parallel inner link plates connected by a pair of hollow bushes. The inner links are connected by a series of outer links. Each outer link comprises a pair of parallel outer link plates connected adjacent the opposite ends thereof by a pair of pins. The pins on a given outer link extend through the bushes on the adjacent ends of two inner links to pivotally connect same together. The inner link plates and the associated bushes forming the inner links are fused together by a fillerless weld formed by electron beam or laser welding. The pins and the outer link plates can be similarly welded together. The resulting chain has substantially increased tensile and fatigue strength.

    摘要： A punching tool particularly for breaking roller chain and the like has a member connected to a pivotally mounted lever and a link. A rack and pinion arrangement permits selective pivoting of the lever for movement of the member and link. The link has one or more punches arranged thereon for engaging a workpiece arranged in a recess provided in a base member pivotally mounting the lever and link. A die communicates with the recess for cooperating with the punch during punching operations. Preferably, a plurality of punches and mating dies are provided for simultaneously punching out a plurality of roller chain pins.
