ABSTRACT:
An improvement of a globoid worm gear generating method based on the "basic member gear theory" and the "secondary action theory" both proposed by the same inventors is disclosed. In one form, the surface of a globoid worm generating tool is defined as the tooth surface of an intermediate gear by a conical surface whose semivertical angle .UPSILON., 0.degree..ltoreq..UPSILON..ltoreq.90.degree.. In another form, the surfaces of a globoid worm gear generating tool are defined by two conical surfaces whose semivertical angles are equal and satisfy the above condition and whose major axes as well as bottoms are coincident with each other so that both tooth surfaces of a worm may be simultaneously generated.
