Gear noise and vibration are troublesome problems in power transmission systems. Recent research has shown that
accuracy in three dimensionaltooth flank form, whichis usuallyrepresentedby toothform and tooth lead form, isan
important factors in noise and vibration.
In this paper theauthorsdiscuss investigationinto whatform accuracyof geartooth flank has agood correlationwith
gear vibration and noise, when the scattering of accuracy in tooth flank form cannot be avoided.
