Selecting a method for reducing friction in rotary refrigeration compressors developed for import substitution

Abstract

The article discusses one of the methods for reducing friction, used for newly developed rotary
compressors as part of import substitution work. The experience of using rotary refrigeration
compressors is analyzed and the main factors determining refrigeration capacity are identified. Methods
used in aerospace engineering and power engineering to reduce friction and increase the service life of
mechanical elements and assemblies using metallic and non-metallic materials have been identified, and
the most promising materials and development trends have been analyzed. A fairly common method of
reducing friction, based on the weariness effect, is chosen for study. Based on already known results, a
technical solution based on the wear-free effect has been proposed to reduce friction of a refrigeration
compressor with a rolling rotor.
