The spherical gear formed by attributing ring teeth on a spherical face is a new type of gear. The spherical gear device can be used to deliver spherical motion. In order to popularize its application, it is necessary to study its manufacture. Base on the study of configuration characteristic of the spherical gear, extending the generating method principle of general gear's manufacture to the spherical gear's manufacture, we ratiocinate out the generating method principle of spherical gear's manufacture. On precondition of applying generating method, we design the scheme of turning and milling of the spherical gear, and we work out a suit of device accessioned on the lathe for manufacturing spherical gears. It provides a basic means for studying the manufacture of spherical gears.
