Abstract
PURPOSE: To form screw rotor of high accuracy and high productivity by forming into an involute gear shape the area where the intersecting point of sectional gear shape vertical to the rotary axle of rotor and its pitch circle is centered.
CONSTITUTION: The involute basal point f is taken on a straight line gear shape connecting the point a on the pitch circli 1' of the female rotor 3' with the point b on a straight line extending toward the axial center O of the female rotor 3' and an involute gear shape passing through the point a toward the point g on the circle of a radius r1 leading to the gear tip 5' of the female rotor 3' is formed. And, the involute basal point F is taken and involute gear from the point f to the point g is designed to gear with the involute gear from the point F to the point G.
