Abstract

This paper presents a comprehensive investigation of the design features, operational efficiency, and dynamic load resistance of a worm gear transmission incorporating a composite elastic element. The structural components of the proposed improved design and their interaction are examined in detail. Experimental results demonstrate that the new design offers significant advantages over conventional worm gears in terms of reduced contact stress, lower noise and vibration levels, and extended service life. The study provides theoretical and practical justification for implementing this design in textile and light industry machinery.
