And face gear used gear transmissions cylindrical pinion with a face gear, in the transmission gear, tools and methods for fabricating the face gear

摘要

In the face gear transmission with (57) and face gear that meshes with it [summary] cylindrical pinion, the theoretical tooth profile of the pinion with a thickness infinitely small (22), tooth trace of the face gear, the center of the pinion It is derived by moving along the imaginary axis that coincides with the rotation axis of the cylindrical pinion. The crowning is to achieve a gap between teeth of the face gear teeth is required. Starting from the definition in diameter between of the maximum and minimum diameters of tooth trace of the face gear, the movement of (22) theoretical pinion tooth profile of the virtual rotation axis, the shape of the teeth of the face gear, the center of the theoretical pinion tooth But, it is adapted to receive at the same time as the vertical displacement (p1, p2) on the virtual rotational axis in the direction toward the tooth trace of the face gear.
