All cross-influences between the machine elements of a complete gear system in operation must be taken into consideration for appropriate gearbox system design. These cross-influences depend on the elasticity of the machine elements, which leads to a complex deformation state.

For the system-level calculation, the power flow and deformations of the entire gearbox are calculated. All forces, displacements, etc. are automatically passed on to the individual machine elements. Thus, deformation cross-influences are considered for all further load carrying capacity calculations. 

For example, the load distribution of cylindrical gears is significantly influenced by the deformation behavior of the shaft-bearing systems and the casing.

Accurate knowledge of these constraints allows engineers to make well-informed decisions on the optimal design of transmission systems early in the development process.
