Recently, plastic gears with high strength and heat resistance have become necessary as office apparatus become compact in size and the operating conditions more severe. Engineering plastics filled in base polymer with glass fiber or carbon have been developed and applied to the gears. The endurance limit or wear resistance of the gears made of these engineering plastics has scarcely been revealed. In this paper, after the features of the errors of these plastic gears were inspected, endurance tests were conducted in order to determine the wear characteristics. It was observed from the results that the glass fiber filled in the plastic gears brought about the abrasive wear on the mating gear teeth. It was concluded that improvement in surface durability of gear pair was attained from selecting the appropriate number of mating gear teeth such as an aliquot number of each other.
