Abstract:
1. A method for designing single-lobe rotors adapted for generating a defined rotor and a conjugate rotor both having a single lobe intermeshing and conjugating to each other by way of appropriate parameters, comprising: curve portions of a single lobe of the defined rotor generated by a curve E, an arc A, an arc B, an arc F, an arc C, an arc H, and a straight line Y, then taking advantage of said curve portions of the defined rotor to generate conjugate curve portion for forming the conjugate rotor, wherein the method for designing a single lobe of the defined rotor comprising: designating a maximum radius R of the defined rotor and a width D of the defined rotor, a pitch circle radius Rp of the defined rotor and the conjugate rotor, a first center t defining a reference horizontal line h designating a second point P defining a second line h defining an arc B by drawing around the third center t defining an arc F by drawing around the second center t defining a third line h designating a center t defining an arc C by drawing around the center t designating a sixth point P defining an straight line Y by straight connecting the point P defining an arc H by drawing around the center t defining an arc G by drawing around the center t generating the curve portion of the single lobe of the defined rotor by linking the curve E, the arc A, the arc B, the arc F, the arc C, the straight line Y, the arc H, and the arc G.
