Purpose of this work is the development of a lumped model of planetary gears, for the estimation of the forces on the gear teeth and for the investigation of the problem of contact losses and tooth wedging. Differently from previous works, which analyzed the behavior of gears with torque and assembly error, this model takes into consideration the effects of parallel offset between the input and outputs shafts on the load sharing factor. The mathematical model is implemented in Matlab© environment. The code estimates the mesh forces on each planet and it can determine the load on each planet. The operating conditions at which wedging is not present can be computed.
