Polycarbonate is a general-purpose engineering plastic which has been widely used, together with nylon and polyacetal. In this plastic, the rate of contraction in molding is small, and the water-absorbing property is low ; therefore, the accuracy of finishing products is high. However, there are defects such as low fatigue strength and brittle fracture, and it has not frequently been used for the gears for power transmission. In this research, for the purpose of extending the practical use of polycarbonate to gears, gears were manufactured of polycarbonate without filling (natural) and of polycarbonate in which the amount of carbon fiber filling was varied, and operation tests were carried out. In this way, such factors as the load-bearing capacity, the wear of teeth and the change of tooth. profile were investigated. These results were compared with those on polyacetal gears previously, reported. Thus the evaluation of polycarbonate as a gear material was carried out.
