Abstract
In the past, the concepts involving secondary measures for the reduction of solid-borne noise emissions of gearings were for the most part aimed at reducing the noise emission rate of the toothed gears. Other secondary measures were not so much concerned with the gears themselves, but with other gearing components. A new approach, however, includes the use of rotating damping disks bolted to the toothed gears. The use of bolted components results in small shifts of the resonance frequencies, in nonlinear effects and finally in friction damping of vibration amplitudes due to energy dissipation. A mathematical model for calculating the damping behavior of rotating damping disks will be developed on the basis of the equations first used by Valanis [4] and will be verified by testing.
