The theoretical thickness modification coefficient, xsmn, determines the relative change of pinion and crown gear tooth thickness to each other. It is related to the mean normal module mmn. The theoretical thickness modification coefficient is used to compensate for the tooth root load capacity on the wheel and pinion.
