Abstract
The present invention provides methods for designing single-lobe or double-lobe rotors which enable a defined rotor and a conjugate rotor intermeshing and conjugating to each other and by parameterized sets to generate curve portions of half two lobes of the defined rotor including a curve E, an arc A, an arc B, an arc F, an arc C, an arc G and a horizontal line Y. The main feature is that a radius of the arc C being defined by following equation: in which ris two times pitch circle radius(Rp) of the defined rotor deducting the maximum radius(R) of the defined rotor(r=2 Rp−R), and a center of the arc C is located in a straight extension direction from a center of the defined rotor and an end point of an arc F.
