A new type hobbed face gear and its application to an automatic circular index table.

The study deals with the development of a new type face gear and the application. The face gear can be easily hobbed by use of a conventional narrow gear hob without any special attachment. Geometrical dimensions and form of face gears are analysed, and face gears were actually produced. The face gear meshing with involute spur gears or helical pinions has advantages of easy setting and smooth mating. Together with applications to robot hand, radial-feed screw cutting device and reel for fishing, the automatic circular index table developed in combination with two different face gears is explained, making use of features of the face gears.
