説明

This paper deals with the gear rattle of helical gear system. Introducing the mesh stiffness variation and the tooth profile error into the equation of motion of one pair of helical gear system, the effects of the mesh stiffness variation, tooth profile error, and torque variation on the rattle are studied by numerical analysis. As a result, the followings were made clear. (1) Higher-harmonic resonances occur because of the torque variation. In the region where the meshing frequency is nearly twice natural frequency, the amplitudes become large by the interaction of the parametric excitation of the mesh stiffness variation and the forced vibration caused by the tooth profile error. (2) There is a possibility that the gear rattle is improved by the tooth profile error, but the amplitude of displacement becomes large depending on the tooth profile error. (3) In the higher-harmonic resonance of the helical gears with tooth profile errors, gear rattle involves short interval impacts, different from the ones without tooth profile errors.
