ABSTRACT:
A screw rotor profile for both male and female rotors is generated from a single rack in which each individual rack segment includes four discrete circular arc segments and two discrete straight line segments. The leading and trailing flanks of the lobes of both the male and female rotors generated by the rack include involute portions disposed between tangent circular-arc-generated portions. A method for developing the rack is also disclosed.
