Recently, for the plastic gears being assembled in sound apparatuses, those having lower noise are desired. For this purpose, it has been attempted to use plastics filled with plasticizers for gears. When plasticizers are filled into plastics, the viscosity increases, while the strength and wear resistance decrease. However, these has been doubt expreassed as to their practicality. Therefore, in this study, gears were made of a material formed by nylon filled with moret than 10% plasticizers. The effect of silencing was confirmed, and the basic characteristics of the gears, such as the wear of teeth and the change of the tooth profile, were experimentally examined.
