Study On The Design And Manufacture Basis And The Motion Characteristics Of The Single Screw Compressor

Single screw compressor(SSC) as the product of sophisticated technology in compressor field, is the one of the equipment which is mechanical and electrical integration of the latest technology. It has many merits, such as the compact structure, the ideal balance of power, the large of standalone capacity, no clearance volume, low noise, little vibration, and so on, which is widely used in air compression, military, petroleum, locomotives, refrigeration, chemical engineering, pharmaceutical, and so forth . CP-type single screw compressor had been studied in this paper, and the main research works are completed as following.The meshing characteristics of screw and gators of the single screw compressor were studied, and the left and right spiral groove surface equations of screw were obtained based on the space meshing theory. The meshing equations of inverse envelope of gators were established, and the tooth profiles of gators were also obtained.The geometry parameters of the single screw compressor were confirmed. The 3D solid models of the key parts of single screw compressor were established, and the virtual assembly of SSC was also completed in the UG system. Then, the kinematics simulation analysis of SSC was completed, and the conditions of the motion of SSC were obtained in the MSC-ADAMS system.The finite element modal analysis of the single screw compressor and the main parts of single screw compressor were completed, the natural frequency and vibration mode diagram of the screw, gators, and the single screw compressor were given in the ABAQUS system. The analysis results verified that the natural frequency of single screw compressor could meet the design requirement.The classification of the rapid prototyping and the principle of the rapid prototyping machine projet3Dsystem SD3000 were introduced. In projet3Dsystem SD3000, the machining of screw and gators were completed. The assembling of screw and gators were carried out, and the operating of screw and gators was flexible, verify the correctness of the theory analysis and modeling.
