This standard specifies the geometry of bevel gears. The term bevel gears is used to mean straight, spiral, zerol
bevel and hypoid gear designs. If the text pertains to one or more, but not all, of these, the specific forms are
identified. This standard is intended for use by an experienced gear designer capable of selecting reasonable
values for the factors based on his knowledge and background. It is not intended for use by the engineering
public at large.
