All the available strength calculations for bevel gears take only tooth geometry in the middle of the tooth width into account. Consequently no difference can be expected in the evaluation of bevel gears that are produced with different processes (Klingelnberg, Gleason, etc.). Likewise, reduction of the calculation to an equivalent cylindrical gear configuration is uniform for all strength calculations. Due to these general restrictions the relevance of the calculations is less than that of the cylindrical gears. However the relevance is wholly adequate for dimensioning the macro-parameters (module, helix angle, addendum modification, etc.), and particularly for comparing variants.
