This paper proposes a simulator which can depict the rotational vibration of a spur gear having any types of tooth surface deviation including both tooth profile deviations and tooth helix deviations. The developed simulator is based on a single degree of freedom motion system constructed with equivalent mass, damping and mesh stiffness of a pair of gears. The mesh stiffness is calculated considering the effect of the tooth helix deviation which brings non uniform load distribution along the contact line of a tooth pair. The dynamic load tests have been performed to verify the simulator changing both helix slope deviation of driven gear and torque. The analytical results under each operating conditions are in good agreement with experimental results. Also, the damping ratio of the test gear system is evaluated as 0.03 with measured vibration responses, which is smaller than conventional expectation value of 0.07.
