method. The tooth shear and bending, root and rim, gear body displacements are calculated analytically. After that, the condition of the deformed gears under load is translated into the evaluation of the STE, considered as the delay of the working gears with respect to the theoretical and infinitely rigid bodies. Once this calculation is completed, the code turns the gears to the next angular position until a defined number of pitch angles is reached.
