The application of additive technologies to manufacture working elements of a singlerotary screw compressor (VKO) at the stage of design and manufacturing is of topical problem. The clearances when a tooth clipper meshing with the central screw was optimized in order to reduce the leakage of compressible medium through the minimal permissible clearances. The methods were developed for 3Dmodeling of a rotor groove profile and a tooth clipper profile of a singlerotary screw compressor by calculation of coordinates of their surfaces using the Java language and SAPR “KOMPAS3D” design systems. The method developed for modeling working elements of a singlerotary screw compressor allows manufacturing a clipper with a tooth of circular shape that exactly follows the rotor groove profile. Ipso facto this improves energy and volume characteristics of a singlerotary compressor manufactured.
The work is dedicated to the centenary of Victor Mikhaylovich Brodyanskiy, Professor of MEI, Doctor of Science, Honoured Worker of Science. Closest colleagues share memories of working together and communicating with Viktor Mikhaylovich. Brief excerpts from his works of the last ten years in the development of concept and exergy methods are given.
