The article deals with the issue of experimental assessment of the dynamics of worm gears. The design of the methodology and the material and technical assurance of experimental tests to determine the impact of the use of various structural modifications on the dynamics of the worm gear are described. In the pilot part of the experiment, a gearbox was tested with an original design solution of bearing the worm wheel shaft in special damping inserts. The goal is to find ways to reduce the dynamic load of the most stressed components of the worm gear and increase their service life.
