Abstract

PURPOSE:To provide forward and backward flank surface of a female rotor at its concave with pressure angles and the convex of a male rotor with a pressure angle by forming it in a tooth shape determined by the concave of the female rotor, in order to make their hobbing easy. CONSTITUTION:A primary portion 9-10 of a forward flank surface 7 is formed in a cycloid tooth shape defined by the convex 6 of a male rotor 2 at one point on its top and secondary portions 10-11 and 13-14 adjacent to the forward flank surface 7 and a backward flank surface 8 are formed in a circular tooth shape with the central point 21 of their circular arcs positioning inside the pitch circle 16 of the female rotor 1. The radius of this circular arc is made larger than an addendum outside the pitch circle 16 of the female rotor 1. Pressure angles thus provided to the forward and backward flank surfaces 7 and 8 and the convex 6 of the male rotor 2 make hobbing by both rotors 1 and 2 easy.
