Problems solved by technology

[0004] The object of the present invention is to provide an asymmetrical elliptical twisted-lobe Roots rotor, compressor, and expander to solve the problem of insufficient space for the design parameters of the original rotor profile of the arc-shaped twisted-lobe Roots compressor in the prior art. The asymmetrical design of the single-tooth tooth profile derived from this can effectively suppress the leakage between the working chambers, thereby improving the overall performance of the twisted-lobe Roots compressor

Abstract

The invention discloses an asymmetric elliptic twisted blade roots rotor, a compressor and an expander. A single-tooth shape B3B2AlA2A3 of a rotor molded line consists of an elliptic arc section A1A2,an elliptic arc section B1B2, an elliptic envelope line section B2B3 and an elliptic envelope line section A2A3 connected end to end in sequence; two rotors can realize correct engagement in the rotary engagement process; the long and short shaft lengths of the elliptic arc section A1A2 and the long and short shaft lengths of the elliptic arc section B1B2 have different values; a complete rotor molded line is formed by repeating the following operations by n times: the single-tooth shape B3B2AlA2A3 is connected with a tooth shape B3B2A1A2A3 end to end after rotation around a rotor molded lineorigin O1; and n is the tooth number of the molded line. The asymmetric elliptic twisted blade roots rotor can effectively inhibit leakage between working cavities to improve overall performance of the twisted blade roots compressor or expander.

Description

technical field [0001] The invention belongs to the field of mechanical engineering, and in particular relates to an asymmetric elliptical twisted-lobe Roots rotor, a compressor and an expander. Background technique [0002] Twisted-lobe Roots compressor is a volumetric rotary compressor, which can be used to obtain medium and low pressure fluid and transport fluid working medium, and has a wide range of applications in modern industry. It has inherited many advantages of rotary machinery, such as long life, reliable operation, small vibration, low noise, stable operation, no surge phenomenon, etc. At the same time, it has no wearing parts such as air valves, forced suction and exhaust, and simple processing. One of the main types of machinery such as battery system air compressors and vehicle superchargers. [0003] The core components of the twisted-lobe Roots compressor are two rotors. The selection of the rotor profile determines the structure of the rotor, which affect...
