The modification of tooth profile (MTP) is very often used for reducing the rotational vibration of a pair of gears for power transmission. But the current MTP cannot eliminate the vibration from a pair of gears completely, because the MTP is not obtained by exact theory. This paper develops the optimum modification of tooth profile (OMTP) of power transmission spur gears to make the rotational vibration equal zero. By minimizing the total equivalent exciting force (TEEF) of a pair of spur gears, the OMTP in the case of any contact ratio can be simply obtained. The magnitude and the shape of the OMTP change markedly with the contact ratio ε, in particular, the concave shape of the OMTP is obtained in the case of ε ≤ 1.1. The authors applied the OMTP to active spur gears, and found that the vibration calculated numerically by the exact nonlinear equation is zero. The slight effect of the variation of the contact ratio, the magnitude of OMTP and the external static load is also investigated.
