PROCEDE DE FABRICATION D'UN ENGRENAGE ROTATIF EN MATIERE THERMOPLASTIQUE ET ENGRENAGE AINSI OBTENU

摘要

This invention discloses a process for producing a low-noise gear. It consists in producing this gear by the technique of co-injection of a hard matter which will form the outer toothing and the axial portion for engagement on the shaft associated therewith, and of a damping matter which will form the heart of the thermoplastics gear.
