DYNAMIC BEHAVIOR OF PLANETARY GEARBOX NEW CONCEPT

, 2013
Noise and vibration have a very negative influence on mechanical gearbox functionality. That is the reason why a lot of attention is given to these analyses. A new concept of planetary gearbox is presented in this paper. Both a two dimensional model, and three dimensional model has been developed. Based on known dynamical models of mechanical gearboxes,
