Abstract


This paper discusses the use of high-performance plastics in worm gear manufacturing, focusing on polyphenylsulfides (PPS), polyvinyl fluorides (PVDF), polyetherimides (PEI), polyethersulfone (PES), and polysulfones (PSU). These materials offer excellent mechanical, thermal, and electrical properties, including wear resistance, dimensional stability, and chemical resistance. The article evaluates the potential of these materials in the worm gear industry, highlighting their advantages over traditional materials like light weight, corrosion resistance, and mechanical performance. The research analyzes the characteristics of these materials and proposes ways to improve gear system performance. The study highlights the advantages of these materials in sectors like the chemical, pharmaceutical, and electrotechnical industries, emphasizing their potential to enhance efficiency and durability of mechanical systems.
