Evaluation of the effectiveness of the surface modification of the working profile gears by composite coverings
It is shown that for a rational choice of the composition of the covering material, type and concentration of alloying elements, as well as the technological parameters of the process cladding by flexible instrument, composite covering helps to reduce noise level bevel gears, and also increases the resistance to the bully and jamming teeth. The most noticeable effect of improving vibroacoustic characteristics of wheels with cladded work profile in comparison with wheels without covering practically throughout the entire spectrum of frequencies ensure provides coverage Бр05С20Гр0,5ДМ0,5 from sintered bronze alloyed components of the solid lubricant. Acceptance tests of experimental batches of gear with a working profile modified specified covering, made in «Minsk plant of automatic lines for them. P.M. Masherov», showed a decrease of noise level in engagement in 3-3,3 dBA compared to the original gear.
