This paper presents a new rotor profile of roots vacuum pump composed of arc, involute and cycloid.It’ s whole tooth profile which is described exactly by combining the meshing principle of gears with parameter equation. The performance of meshing of two rotors is improved without profile interference and packet gas, which are the problems of conventional involute profiles. The work provides new theoretical basis for digital design of new rotor profile, its meshing analysis, dynamic emulation, kinematics and dynamics analysis.
