"IMPROVEMENTS IN THE CONSTRUCTION OF TRAPEZOID PULLEYS" that are characterized by the pulley either in one piece or formed by coupled discs, has a central hole with conical surface whose pulley is coupled to a bushing of elastic material, split by a groove longitudinal and with the conical outer surface and equivalent to the surface of the central hole of the pulley, so that the machine axis being fitted to the bushing, the adjustment occurs as the pulley moves relative to the bushing by means of threaded elements passers to the pulley that compress to this by means of a common flange fitted in the aforementioned bushing, so that when contracting the diameter of the bushing due to the displacement of its external conical surface with respect to the internal conical surface of the pulley, the adjustment takes place. to the shaft to which the assembly is attached.
