Abstract
This study has revealed by taking nondimensional measures that the vibrational characteristics, basically the behaviour of stiffness, of helical gear pairs whose transverse and overlap contact ratios are invariant are identical. The feature is colligated correspondingly at the point on the contact ratio domain by the coordinate of their transverse and overlap contact ratio.
By the colligation, the charts have been proposed as named the performance diagram on vibration, which indicate the level of vibration of a pair by contour lines on the contact ratio domain, after the vibrations of helical gear pairs are calculated by a developed simulator.
The work has established the method of easy design and improvement for the lower vibration helical gear pair by a cursory glance at these proposed diagrams.
