Face gears can be substituted for bevel gears or hypoid gears. However they can be used only in restricted applications today. Recently, a new application of face gears for helicopter transmissions has been proposed and face gears have attracted special interest. In the face gears, generally, the pinion is a conventional spur or helical gear with involute form. Therefore, when the gear dimensions were given, there is little degree of freedom for the gear design. So, a face gear adopting arcuate tooth profile on the pinion has been proposed. And the effects of the radius of the arcuate tooth profile on the constitution of the surface of contact and on the tooth contact patterns have been clarified. This paper presents a new type face gear using the feature mentioned above. The meshing performance of the proposed face gear is similar to that of WN gear.
