Short summary
This paper investigates planetary gear reducers with double satellite gears. These reducers are present in present-day industrial robots, electric vehicles, etc. The paper deals with the dynamic behavior of the reducer as a whole system. The acceleration, velocities, and movements are solved for all elements based on the defined dynamic model. For a dynamic model definition, we used Lagrangian equations of the second kind. The results can be used in design, investigation, etc.
