Abstract

In the fields of air/gas compression, refrigeration, and chemical fluid transportation systems, single-screw compressors are widely used. A screw rotor and two gate rotors located at both sides are the main components of a single-screw compressor. Because of this simple construction, it has merits of low rotational speed of the rotor, efficient compression with low noise, low vibration, and long bearing life. However, it is difficult to design single-screw compressors. To accelerate the design and manufacturing of single-screw compressors, a design method for a gate rotor using coordinate transformation and numerical estimation by iteration of edge points is presented in this paper. The lines connecting the edge points can be used for CAD/CAM data for design and machining.
