A model of a high-speed, four-path, load-share gear transmission system is developed which includes the dynamics of bearings, gear teeth and elastomeric load-share gears. Rigid-body and lumped-parameter approximations are used in developing the model. The modified Newton-Euler formulation is used and its advantages over the conventional Newton-Euler formulation for high-speed transmission modeling are demonstrated. The model is used to study the effects of load-share gear configurations on dynamic transmission loads and system behavior during operation of the system. It is found that small asymmetries in the load-share gears can cause significantly elevated dynamic loads and moments to act on the main transmission shaft.
