A study of fiber-filled plastic gears. (3rd report. Fundamental characteristics of plastic gears made of thermoplastic resin filled with various fibers).

Abstract

This study aimed to elucidate the fundamental characteristics of the composite plastics that adopt thermoplastic resin as the basic material, and in which various fibers are filled, when they are applied to gears. In this case, polyacetal was used as the basic material, 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 so on of the respective gears were examined. In this way, the features were elucidated by comparing those with the case of polyacetal gears.
