Abstract
The present invention provides a method for designing lobe-type rotors which enables a defined rotor and a conjugate rotor with three or more than three lobes intermeshing and conjugating to each other; by setting suitable parameters to generate a curve portion of a single lobe of the defined rotor as a pattern including a curve E, an arc A, an arc B, a straight line Y, an arc C and an arc F, then imaging (N-1) copy of the curve portion in which N represents number of lobes and is bigger than or equal to three, and then respectively rotating each curve portion in sequence from an appropriate degree computed by 360/N to a terminal degree computed by (N-1)*360/N; whereby to integrately form the defined rotor with three or more than three lobes.
