フェースギヤ歯面のすべりに関する一考察

抄録

The purpose of this study was to simplify the design of the tooth surface of face gear and to clarify the optimization method of the specification setting. Face gears have long been used in fishing spinning reels as a speed-increasing gear. Recently, face gears have also been adapted to geared motors for orthogonal reduction gears. However, the design method of the face gear is not supported by a standard theory, and its application is not common. To clarify the meshing of the face gear, the author introduced the idea that the meshing contact progresses along a straight line of action. The meshing point between the involute helical and face gear proceeds at a constant speed along the straight line of action. The velocity vector at the meshing point was divided into the direction of the line of action and the direction orthogonal to the line of action, and defined as the vector of the relative sliding velocity on the tooth flank. This clarified the sliding state of the tooth surface of the face gear.
