One core contents of the rotary compressor is the design of the rotor. During the operation of the existing rotor, the meshing state will become worse and the transmission effect will be poor. Based on the generating principle of involute and the meshing theory of plane curve, the model and analytical equation of eccentric involute and its envelope are established, a eccentric involute rotor is proposed, the parameter equation and value range of the rotor are obtained, and the mathematical program of constructing the rotor is compiled. The influence of geometric parameters on the rotor is analyzed and the appropriate geometric size is obtained. The relative clearance volume is compared, the meshing correctness of the rotor is verified, the stress distribution and mechanical properties of the rotor are analyzed, and the sliding ratio of the rotor is calculated. The eccentric involute rotor has the advantages of good meshing performance and stable and reliable transmission.
