Dynamic Model of Differential Closed Planetary Gearing and the Spectrum of its Eigenfrequencies

Resumo

Problems that arise in the construction of dynamic models of differential closed planetary gearing used in drilling technology are considered. The influence of the parameters of the system on the eigenfrequencies of the oscillations of the dynamic model is estimated by serial variation with step 0.5 of all the elastic-inertial parameters in the range 0.5–2.0 from their computed values.
