Problems solved by technology

At present, the profile line of the existing screw compressor rotor is a unilateral asymmetric cycloid-pin-tooth circular arc line. As the distance between the apex of the contact line of the male and female rotors and the intersection point of the rotor addendum circle increases, the axial airtightness decreases. , the efficiency is low, and the root of the male rotor has sharp points, which form stress concentration, which is not conducive to bearing large loads, and is not convenient for processing and testing

Description

Technical field: [0001] The invention relates to a rotor, in particular to a screw compressor rotor. Background technique: [0002] In screw compressors, the shape of the rotor basically determines the performance of the screw compressor. At present, the profile line of the existing screw compressor rotor is a unilateral asymmetric cycloid-pin-tooth circular arc line. As the distance between the apex of the contact line of the male and female rotors and the intersection point of the rotor addendum circle increases, the axial airtightness decreases. , the efficiency is low, and the dedendum of the male rotor has sharp points, forming stress concentration, which is not conducive to bearing large loads, and is not convenient for processing and testing. Invention content: [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the above-mentioned prior art and provide a screw compressor rotor with smooth meshing, reduced wear, g...
