Fundamental Characteristics of Plastic Gears Made of Thermoplastic Resin Filled with Various Fibers

抄録

This study aimed to elucidate the fundamental characteristics of the composite plastics that adopt thermoplastic resin as the matrix (basic material), and in which various fibers are filled, when they are applied to gears. In this case, polyacetal was used as the matrix, and glass fibers, carbon fibers or potassium titanate whiskers were used to fill it in. Gears were made with these composite materials, and the wear of teeth, the change of the tooth profile, the temperature on tooth surfaces and other characteristics of the respective gears were examined. In this way, the features were elucidated by comparison with those in the case of polyacetal gears.
