Abstract: Helical gears adapted to mesh while rotated about parallel axes, are finished by meshing engagement with a shaving cutter gear rotated about an axis at a fixed cutting angle to the rotational axis of the helical gear being finished. A contact ratio close to but never less than one is established during meshing engagement between the helical gear being finished and the finishing gear by designing the helical gear teeth profiles within the limits of a contact ratio range applicable to meshing helical gears rotating about parallel axes.
